The study was performed in accordance with the scope of work in our Proposal No. P -13 -163 to SDG, Incorporated, dated January 31, 2013. Based on our recent experience for the project which included a design geotechnical engineering study and environmental hazardous materials services, we understand that the existing reservoirs will be replaced with two underground tanks with a capacity of 20 million gallons. Several municipal owned and maintained streets will be used as truck haul traffic routes associated with removal of the demolition materials from the site, the removal and replacement of existing earth embankments and construction materials to be delivered to the site for the new tanks. This Pavement Condition Assessment study was performed to help determine the potential impacts to the municipal streets as a result of the Project's truck haul routes. An initial Pavement Condition Assessment was performed prior to the start of construction and associated haul traffic to determine and document the condition of the pavement sections. A second Pavement Condition Assessment will be performed at the end of the haul traffic to determine the condition of the streets and the repair strategies needed to bring the pavement back to a condition as if Project truck traffic never used the roadways during the construction period. The Pavement Condition Assessment was performed for the following streets: Street Name From To W. 20th Avenue KiRling Street Quail Street Quail Street 20` Avenue One Block South W. 29 Avenue Gray St Sheridan Blvd. W. 30' Avenue Fenton Street Harlan Street W. 32" Avenue Harlan Street Sheridan Blvd. Fenton Street W. 29 Avenue W. 3 01h Avenue Harlan Street W. 30` Avenue W. 32" Avenue The project street alignments fall under the jurisdiction of the City of Wheat Ridge with the exception of West 20` Avenue and Quail Street which are in the limits of the City of Lakewood. Also, both directional travel lanes and associated parking stalls /shoulder areas have been evaluated for the project. Kumar & Associates, Inc. rA This report has been prepared to summarize the data obtained during this study and to present our conclusions and recommendations based on the proposed use of the roadways. ROADWAY CONSTRUCTION HISTORY As part of the background research for the Pavement Condition Assessment study, we requested from the City of Wheat Ridge and the City of Lakewood all documentation related to the roadway history. Some of the information requested included topographic surveys, roadway plans and profile, utility locations, pavement thickness, overlay history, and existing pavement condition survey information. The City of Lakewood indicated that none of the requested information was available. The City of Wheat Ridge provided limited documentation of each roadway segment within their City limits. Within the project limits, the City of Wheat Ridge's documentation included approximate pavement surface areas. approximate pavement thickness, construction date and subsequent maintenance type and date performed to the roadways. The documentation provided to us by the City of Wheat Ridge is provided in Appendix B of this report. METHODOLOGY The Pavement Condition Index assessment utilized procedures outlined in ASTM D 6433 to determine a pavement condition rating. The pavement condition rating consists of a Pavement Condition Index (PCI), which is based on a scale of 0 to 100. The PCI measures the structural integrity and surface condition. The scale and ratings associated with the PCI are shown on Figs. 2 through 8. The PCI is determined by measuring pavement distress. The first step in the study was to identify each roadway within the actual network of the roadway system. A roadway may be divided into separate rehabilitative sections based on different construction history, different pavement sections, and /or different traffic loadings. The roadways in the study area had only one section since each roadway was generally constructed during one construction period and were constructed of a similar pavement type. Each section was subdivided into sample units. The sample unit sizes were 100 feet in length by the width of the roadway. Each roadway had a differing number of sample units depending upon the actual roadway length. All of the sample units in each roadway segment were visually inspected. A sample unit was visually observed to determine the types of distress, and then each type of severity of distress was physically measured. After all of the sample units were visually characterized, the data was reduced using the ASTM prescribed equations and charts to weight Kumar & Associates, Inc. 3 each type of distress and to normalize the values to fit into the PCI rating system. The values obtained from each roadway segment are graphically plotted on Figs. 2 through 8. PAVEMENT SECTION SUMMARY A summary of the PCI values for each segment of each roadway is provided in Appendix A. Descriptive summaries of each roadway follows: West 20 'h Avenue West 20` Avenue is located within the city limits of the City of Lakewood. We were informed that there was no information available with regards to the pavement construction and maintenance history. The roadway was paved with asphalt pavement and had portions with concrete curb and gutter as well as portions with unpaved shoulders and roadside ditches. The asphalt pavement surface ranged from 34 to 40 feet wide and was striped as a two lane roadway between Quail Street and Miller Street. The roadway between Miller Street and Kipling Street was striped as a two lane roadway with wider areas of pavement that were used to facilitate turning movements. A plan sheet showing the roadway alignment and the PCI for each segment in the alignment is presented on Fig. 2. The average weighted PCI calculated for West 20` Avenue was 75. Most of the weighted PCI values for each segment along the roadway alignment generally varied from 66 to 86; however, a segment exhibiting a PCI value of 32 was noted just west of Oak Street. The segment west of Oak Street received a low rating primarily due to minor rutting noted in the segment. The PCI value also dropped to 60 near the intersection with Kipling Street. The lower value at Kipling Street was also the result of some rutting noted near the intersection. A plan sheet showing locations and types of distresses observed during the assessment is provided on Fig. 9. The figure provides photographs of specific areas of distress and is not intended to provide a complete photographic log of the roadway segment. A summary of the each distress type and severity for the roadway is presented in Appendix A. Quail Street Quail Street is located within the city limits of the City of Lakewood. We were informed that there was no information available with regards to the pavement construction and maintenance history. The roadway was paved with asphalt pavement and had portions with concrete curb and gutter as well as portions with unpaved shoulders and roadside ditches. The asphalt pavement surface ranged from 25 to 30 feet wide and was not striped. Kumar & Associates, Inc. 4 A plan sheet showing the roadway alignment and the PCI for each segment in the alignment is presented on Fig. 3. The average weighted PCI calculated for Quail Street was 73. The weighted PCI values for each segment along the roadway alignment varied from 69 to 78. A plan sheet showing locations and types of distresses observed during the assessment is provided on Fig. 10. The figure provides photographs of specific areas of distress and is not intended to provide a complete photographic log of the roadway segment. A summary of the each distress type and severity for the roadway is presented in Appendix A. West 29 `h Avenue West 29 Avenue is located within the city limits of the City of Wheat Ridge. We were informed that there was limited information available with regards to the pavement construction and maintenance history. The information that we were provided is shown in the Appendix B of this report. Specifically, the information indicates that the roadway was initially constructed in 1921. A complete reconstruction was performed between Fenton Street and Gray Street in 1990 and a complete reconstruction was performed between Sheridan Boulevard and Fenton Street in 2000. An approximate 2 -inch asphalt mill was performed in 2011 for the segment between Gray Street and Fenton Street and an overlay was constructed for the same segment in 2012. Crack sealing occurred in 2005 and 2009 for the segment between Sheridan Boulevard and Fenton Street, and in 2001, 2005 and 2007 for the segment west of Fenton Street.. The roadway was paved with asphalt pavement and had portions with concrete curb and gutter as well as portions with unpaved shoulders and roadside ditches. The asphalt pavement surface ranged from 25 to 36 feet wide and was striped as a two lane roadway. The roadway near Sheridan Boulevard was striped to accommodate two through lanes of traffic and a turn lane from eastbound 29 Avenue to northbound Sheridan Boulevard. A plan sheet showing the roadway alignment and the PCI for each segment in the alignment is presented on Fig. 4. The average weighted PCI calculated for West 29` Avenue was 73. The weighted PCI values for each segment along the roadway alignment generally varied from 68 to 87. A segment exhibiting a PCI value of 31 was noted just west of Fenton Street. The segment west of Fenton Street received a low rating primarily due to a large volume of low severity edge cracking, low severity longitudinal and transverse cracking, and low severity patching. The PCI Kumar & Associates, Inc. 5 value also dropped to 30 near the intersection with Sheridan Boulevard. The lower value at Sheridan Boulevard was largely the result of low to high severity rutting near the intersection. A plan sheet showing locations and types of distresses observed during the assessment is provided on Fig. 11. The figure provides photographs of specific areas of distress and is not intended to provide a complete photographic log of the roadway segment. A summary of the each distress type and severity for the roadway is presented in Appendix A. West 30 1h - Avenue West 30 Avenue is located within the city limits of the City of Wheat Ridge. We were informed that there was limited information available with regards to the pavement construction and maintenance history. The information that we were provided is shown in the Appendix B of this report. Specifically, the information indicates that the roadway was initially constructed in 1921. A complete reconstruction was performed in 1986. It appears that routine maintenance was performed for the entire roadway segment in the form of crack sealing and slurry sealing between 1995 and 2007, slurry seal in 1995 and 2007 with crack sealing in 2001 and 2005. The roadway was paved with asphalt pavement and had concrete curb and gutter along the entire alignment. The asphalt pavement surface was about 40 feet wide. A plan sheet showing the roadway alignment and the PCI for each segment in the alignment is presented on Fig. 5. The average weighted PCI calculated for West 30 Avenue was 76. The weighted PCI values for each segment along the roadway alignment generally varied from 66 to 90. In general, the roadway received relatively high ratings due to the slurry seal and crack sealing activities performed in 2007. A plan sheet showing locations and types of distresses observed during the assessment is provided on Fig. 12. The figure provides photographs of specific areas of distress and is not intended to provide a complete photographic log of the roadway segment. A summary of the each distress type and severity for the roadway is presented in Appendix A. West 32 2d Avenue West 32 Avenue is located within the city limits of the City of Wheat Ridge. We were informed that there was limited information available with regards to the pavement construction and maintenance history. The information that we were provided is shown in the Appendix B of this report. Specifically, the information indicates that the roadway was initially constructed in 1921. A complete reconstruction was performed in 1997. It appears that routine Kumar & Associates, Inc. 0 maintenance was performed for the entire roadway segment in the form of crack sealing in 2001. 2005, 2010 and 2011. The roadway was paved with asphalt pavement and had concrete curb and gutter along the entire alignment within the project limits. The asphalt pavement surface ranged from 28 to 30.5 feet wide and was striped as a two lane roadway. The roadway between near Sheridan Boulevard was striped to accommodate two through lanes of traffic and a turn lane from eastbound 32 " Avenue to northbound Sheridan Boulevard. A plan sheet showing the roadway alignment and the PCI for each segment in the alignment is presented on Fig. 6. The average weighted PCI calculated for West 32 " Avenue was 82. The weighted PCI values for each segment along the roadway alignment generally varied from 75 to 93. A segment exhibiting a PCI value of 16 was noted just west of Sheridan Boulevard. The lower value at Sheridan Boulevard was largely the result of low to high severity rutting near the intersection. A plan sheet showing locations and types of distresses observed during the assessment is provided on Fig. 13. The figure provides photographs of specific areas of distress and is not intended to provide a complete photographic log of the roadway segment. A summary of the each distress type and severity for the roadway is presented in Appendix A. Fenton Street Fenton Street is located within the city limits of the City of Wheat Ridge. We were informed that there was limited information available with regards to the pavement construction and maintenance history. The information that we were provided is shown in the Appendix B of this report. Specifically, the information indicates that the roadway was initially constructed in 1921. An approximate 2 -inch asphalt overlay was constructed on the roadway in 1979. It appears that routine maintenance was performed for the roadway segment in the form of crack sealing and slurry sealing between 1995 and 2005, . a slurry seal in 1995 and crack sealing in 2001 and 2005. The roadway was paved with asphalt pavement and had concrete curb and gutter along the entire roadway alignment. The asphalt pavement surface was 31.5 feet wide and was partially striped as a two lane roadway near the intersection of West 29 Avenue. Kumar & Associates, Inc. 7 A plan sheet showing the roadway alignment and the PCI for each segment in the alignment is presented on Fig. 7. The average weighted PCI calculated for Fenton Street was 39. The weighted PCI values for each segment along the roadway alignment generally varied from 17 to 71. The roadway had higher PCI values (44 to 71) near the intersection of West 30` Avenue and deteriorated to lower PCI values (17 to 40) near West 29` Avenue. The low PCI values are generally the result of load related distresses in the form of low to high severity alligator cracking and potholes. A plan sheet showing locations and types of distresses observed during the assessment is provided on Fig. 14. The figure provides photographs of specific areas of distress and is not intended to provide a complete photographic log of the roadway segment. A summary of the each distress type and severity for the roadway is presented in Appendix A. Harlan Street Harlan Street is located within the city limits of the City of Wheat Ridge. We were informed that there was limited information available with regards to the pavement construction and maintenance history. The information that we were provided is shown in the Appendix B of this report. Specifically, the information indicates that the roadway was initially constructed in 1955. It appears that routine maintenance was performed for the entire roadway segment in the form of crack sealing and slurry sealing between 1989 and 2007, slurry seals in 1996 and 2007 with crack sealing in 2001 and 2005. The roadway was paved with asphalt pavement and had concrete curb and gutter along the entire alignment. The asphalt pavement surface ranged from about 24 to 25 feet wide. A plan sheet showing the roadway alignment and the PCI for each segment in the alignment is presented on Fig. 8. The average weighted PCI calculated for Harlan Street was 81. The weighted PCI values for each segment along the roadway alignment generally varied from 64 to 92. In general, the roadway received relatively high ratings due to the maintenance activities performed on the pavement surface and the apparent low traffic volumes. A plan sheet showing locations and types of distresses observed during the assessment is provided on Fig. 15. The figure provides photographs of specific areas of distress and is not intended to provide a complete photographic log of the roadway segment. A summary of the each distress type and severity for the roadway is presented in Appendix A. Kumar & Associates, Inc. 0 CONCLUSIONS AND CONSIDERATIONS Generally the roadways addressed in this pavement condition assessment were in Fair to Good condition, although there are areas already damaged that will likely deteriorate quickly with the anticipated construction traffic. Specifically, the areas at major intersections such as 20 Avenue at Kipling and Oak Street, 29 Avenue at Fenton Street and Sheridan Boulevard, and 32 Avenue at Sheridan Boulevard. Fenton Street is also currently exhibiting significant load related distresses and will likely further deteriorate quickly with the application of construction traffic. We do not have accurate pavement section thickness data for the roadways. so it is difficult to estimate the performance of the roadway pavements with regards to the increased load applications of construction traffic. Based upon review of the data, field observations, and the assumed roadway classifications we anticipate that 20 Avenue, 32 Avenue and 29 Avenue from Fenton Street to Sheridan Boulevard should perform well with a minimal increase in the rate of deterioration of the pavement structure. The confidence level in the remaining roadways is less due to their assumed residential roadway classifications. We anticipate that Quail Street, Fenton Street, 30" Avenue, and Harlan Street may experience significant increases in deterioration. We are not able to accurately estimate the level of deterioration the roadways will experience; however, repairs during construction and after construction will likely be required to Quail Street, Fenton Street. 30" Avenue, and Harlan Street as well as at the intersections described above. Areas of Acute Distress We believe that most of the roadways addressed in this report, with the exception of the residential roadways identified above, will generally withstand the anticipated construction traffic while providing a reasonable pavement surface for the traveling public. However, we did note areas in the residential roadway alignments that are already damaged. Harlan Street about 200 to 300 feet north of West 30 Avenue has several damaged areas of pavement along the west side of the roadway. We estimate the areas to be in the range of about 1,000 to 1,500 square feet. Most of Fenton Street is questionable for adequate structural capacity based on its current distress and overall condition. Specifically, Fenton Street beginning at the intersection with West 29 Avenue extending north approximately 150 feet is exhibiting moderate to high severity Kumar & Associates, Inc. X , load related distresses such as alligator cracking. Other areas along Fenton Street also appear to be showing indications of distress that could accelerate the deterioration of the pavement surface with increased traffic loadings. At the time of the study, the combination curb, gutter and sidewalk along the east side at the southern end of the alignment was being removed and replaced. We assume that the 2- to 3 -foot patch that will be constructed adjacent to the new concrete will be inspected by the City so that adequate compaction of the subgrade and asphalt pavement is achieved. We estimate the more distressed areas to be approximately 2,000 to 2,500 square feet. Monitoring of the roadway segment should occur during the construction period.

This is by no means a final list but more of a starting point, It would be nice to have all items discusse in one meeting but if necessary we could have multiple meetings as required to get the correct COWR staff involved in the specific discussion item(s).

The demolition of the existing west basin is scheduled to begin in early March with construction of new tanks to follow. Total duration of the project is estimated to be four years. Western Summit Constructors is the construction manager for this project. Western Summit has retained Behrens & Associates Environmental Noise Control, a professional noise & vibration consultant who has developed specifications for the allowable noise & vibration limits during construction. These specifications have been designed to limit the amount of vibration so that no damage to adjacent properties is anticipated. Vibration monitors will be installed to monitor the actual vibration levels during construction. Please contact Matt Cott with BAENC at 970-535-9000 if you should have any questions. You may also call Western Surrunit Constructors Ashland Tank Reservoir information line at 303-325-0588 or send us an email (A-shiandLii)westemsumniit.cc)iii), Thanks in advance for your cooperation.

I understand the area to the west of the drive is an easement which provides driveway access for the residence at 5831 W 29 Avenue, The solution recommended • our staff is to relocate your driveway to the far east side of the parking area, as far away from Gray Street as possible. This will allow you to install landscaping on the east side of the existing easement which will fulfill the intent of an enhanced landscape buffer between the Denver Water and residential properties. I have roughly illustrated that solution in the attached plan. The change should be reflected in the plans submitted for the building permit. Please feel free to be in touch with any further questions. 1071 M I m. City of lT CONFIDENTIALITY NOTICE: This e-mail contains business-confidential information.

I. REQUEST The applicant has prepared application binders for reference by City Council which include information pertinent to this request (Exhibit 1, Application binder). Throughout this report, there will be references to the different components of the request which are arranged by tabs in the application binder. There are also several other exhibits attached separately which will also be referenced in the report. The site is zoned Residential -One (R -1), a zone district that provides for high quality, safe, quiet, stable, and low- density residential neighborhoods, and prohibits activities of any nature which are incompatible with the low- density residential character. Quasi - governmental uses are permitted in the R -1 zone district, but quasi - governmental uses with outside storage require a Special Use Permit (SUP). The Special Use Permit is also required based on the scope of the excavation and fill operations for construction. The SUP and variance requests are being processed simultaneously. The variances will be addressed separately from the Special Use Permit (Application Binder — Tab A, Letter of Intent). Section 26 -114. (Special uses) of the Zoning and Development code defines the purpose of special uses as follows: "Special uses are discretionary uses which, if properly designed, developed, operated and maintained, may be approved for any specific location within a zone district wherein the special use is enumerated. The primary issues to be addressed are those related to justification of need and special design and operational considerations which mitigate potential detrimental impacts of a special use on surrounding land uses, the street system, or public services or facilities. In order to protect the public interest, a special use may be approved, approved with modifications or denied." This request started as an administrative application considered by the Community Development Director but because written concerns /objections were received during the administrative noticing period, it is being forwarded to City Council for a public hearing (Exhibit 2, correspondence received). II. PROPERTY DESCRIPTION /HISTORY The property is zoned Residential -One (R -1) and is almost entirely surrounded by residential neighborhoods. To the north and west are properties zoned Residential -Three (R -3). To the south is a single - family neighborhood zoned Residential -One C (R -1C). Across Fenton are properties zoned R -3, R -3A, and Commercial -One (C -1); these lots include the Wheat Ridge Manor Nursing Home, a gas station, and an auto repair shop. To the southwest across W. 29 Avenue are properties outside the boundary of the City of Wheat Ridge in the City of Edgewater. The site contains Denver Water's Ashland Facility which includes two underground reservoirs with a combined storage capacity of 41 million gallons of water (19 million and 22 million, respectively). The site has been home to a treated water facility since the late 1800's. A series of upgrades have occurred over the last 100 years, including the installation of a precast concrete roofing system in the 1970s. This roofing system exists today and covers a majority of the site. SUP -12 -03 /Ashland Reservoir 2 The elevation of W. 30 Avenue is nearly 20 feet higher than W. 29 Avenue. Steep berms run along the south and west property lines, and a retaining wall has been constructed along Fenton to accommodate the topography of the site. A small well house is located on the south side of the property. A chain link fence surrounds the entire property, and the primary vehicular access point is from W. 30 Avenue. The Ashland Facility is one of only a few reservoirs in the north end of the region. Ashland is primarily fed by Denver Water's Moffat Treatment Plant at W. 20 Avenue and Quail Street. There is no pump station on the subject property and the water is transported by gravity flow east to Denver. The property is currently nonconforming relative to structure setbacks, building coverage, landscaped coverage and fencing with barbed wire along the top. A site plan showing the existing conditions is included under Tab E (Application Binder - Tab E, Sheet 2 of 21, existing site plan). III. CASE ANALYSIS Site Plan The applicant, Denver Water, is proposing to demolish the existing reservoirs and construct two concrete water tanks that are 256 feet in diameter. Each tank will accommodate 10 million gallons of water; they will be 28 -30 feet deep, but only one to two feet will be visible above grade. The existing facility is deteriorating and has reached the end of its useful life. In addition, the existing reservoirs provide excessive storage capacity, which when combined with degradation has created water quality concerns. The replacement project is expected to begin construction in October 2012 and take approximately three years to complete. In addition to replacing and downsizing the reservoirs, the redesign will reduce the amount of impervious surface and address the aesthetics of the facility. The basins will consume the northern two - thirds of the site and the southern portion will be landscaped to more gradually accommodate the change in elevation. A detention pond will be located at grade at the intersection of W. 29 Avenue and Fenton with a small pull -off parking area for maintenance visits. An unmanned water quality facility is planned to be located on the northern portion of the site in proximity to 30 Avenue. The existing chain link fence is proposed to be replaced with a more decorative eight -foot high wrought -iron fence (Application Binder, Tab E, Sheet 3 of 21, proposed site plan). Primary vehicular access to the water tanks will still come from W. 30 Avenue, and a driving path will encircle the two basins. Following the replacement of the basins, Denver Water also seeks to upgrade piping and drain lines within surrounding rights -of -way, including Gray Street, Fenton Street, and W. 29 Avenue to Sheridan. Landscaping Section 26 -502 of the zoning code establishes landscape standards for nonresidential development. The proposed site plan shows that roughly 55% of the site will be covered with live landscaping which exceeds the 25% minimum coverage for non - residential construction. The site plan also meets the requirement for numbers of trees and shrubs required. An eight -foot high wrought -iron fence will SUP -12 -03 /Ashland Reservoir 3 surround the property. It has been suggested that the fence be upgraded with brick columns; however, Denver Water views this as a safety concern (Exhibit 3, Austin letter). Well house /monitoring station There is an existing well house /monitoring station on the southern side of the property. It is octagonal in shape with a river rock foundation, brick construction with windows /glazing on each of the eight facades and a red shingled roof. With 256 square feet of area, it appears to have been built sometime in the early 20 century. This structure is proposed to be demolished as part of the project. A new structure is proposed for the northern portion of the site. With 380 square feet of area, it is denoted on sheet three of the site plan as a water quality building. The area of the structure includes valve vaults which comprise a total of 870 square feet. This proposed structure facade can be viewed on sheet 11 of the site plan package. It is proposed to be split -faced and smooth-faced concrete block with a shed -style roof. High windows are proposed at the offset roofline facing east (Application binder — Tab E, Sheet 11 of 21, building elevations). Staff concludes that the proposed new structure is functionally designed with no interesting attributes. Although it is a relatively small building in an unusual context (public utility structure), the monitoring station is required to meet the standards of the Architectural and Site Design Manual (ASDM). As designed, it is inconsistent with the ASDM in the following areas: facade articulation, materials used and transparency /glazing. It is interesting to note that the existing well house with varied materials, attractive design details, windows and historic appearance is in conformance with the ASDM. Staff is recommending as a condition of the motion that the new structure be redesigned to emulate the existing well house in shape and materials to provide a reference to the historical significance of the property. An alternative would be to rebuild the existing structure somewhere else on the property, even if it is not functional. View of well- house from W. 30 Avenue SUP -12 -03 /Ashland Reservoir 4 Public improvements installation Denver Water will • responsible for installation of new six-foot wide detached sidewalks and six-foot tree lawns with street trees along both Fenton and 30 th Avenue. West 29 th Avenue currently veers slightingly south as it approaches the Fenton Street intersection. A small portion of right-of-way will be dedicated and the street reconstructed in this area to straighten it out which will include installation of new curb, gutter and detached sidewalk with street trees planted at 35-foot intervals. Hauling routes There are several primary construction operations during the project which will impact adjacent streets. Due to concern from impact on surrounding public streets, the haul operation routes have been confined as much as possible to state highways; avoiding streets owned by Wheat Ridge, Edgewater and Lakewood. SUP- 12-031AshIand Reservoir 5 frontages, (29 Fenton and 30 the 30 -foot setback is required on all three sides. The applicant is requesting a setback variance from Fenton of 4 foot, 3 inches relative to the east tank location. Fence height The maximum fence height in the City's zone districts is six feet.. The existing fence is a six -foot chain -link with barbed wire on the top, lending a prison -like appearance. The applicant is requesting an eight -foot high fence for security purposes with upgraded fence materials (wrought iron). Staff is recommending the brick or masonry columns be interspersed every 100' similar to the fence around the Moffat Treatment Plant at 20 and Oak. Denver Water views these columns as safety hazards. Detail of perimeter fence at Moffatt Water Treatment plant at 20 Oak Residential Screening Section 26 -502 (Landscaping) of the zoning and development code requires residential buffering by either a six -foot high solid fence or landscaped hedge or a 15 -foot wide strip of landscaping with one shrub or tree for every two linear feet. Adjacent residential development abuts the development site on the south and western sides. Both of these residential areas are substantially lower with slopes between the homes and the top of the subject property. While there is at least 15 feet of landscaping adjacent to the residential neighbors, the slopes eliminate the option of tree and shrub installation. For security purposes, a solid fence does not meet the standards for Denver Water properties. Staff concludes that the change of grade provides adequate buffering for adjacent residential properties. Staff recommends that additional plantings be shown on the western side of the access drive from W. 29 Avenue. Construction hours Section 26 -623 of the zoning and development code regulates excavation and deposit control operations. One of the performance standards which fill operations must comply with are hours of operation from 7 AM to 5 PM on weekdays. Operations are restricted from occurring on Saturdays, Sundays and holidays. SUP -12 -03 /Ashland Reservoir 7 There are several times during the construction period when these hours need to be extended to complete critical pours of the roof slabs and floor decks for each tank. This could include work after hours and on weekends. Variance criteria In order to approve a variance, City Council must determine that the majority of the criteria for review listed in Section 26- 115.C.4 of the City Code have been met. Staff provides the following review and analysis of the variance criteria (Application binder — Tab C, Applicant's responses to variance criteria). 1. The property in question would not yield a reasonable return in use, service, or income if permitted to be used only under the conditions allowed by regulation for the district in which it is located. The reservoir could either remain as a deteriorating structure or be rebuilt. The proposed variances are primarily due to the unusual nature of the structure being built and the site characteristics. According to Denver Water, the reservoir is a critical component of water service to the Denver metro area which may mean that there may not be viable alternatives other than rebuilding the facility. The variances requested are based on the site configuration, functionality and safety of the operation and construction requirements. Staff finds that this criterion has been met. 2. The variance would not alter the essential character of the locality. The issues of variances on their own will not alter the character of the locality and may not be discernible to the public eye. This is an area where most of the home construction occurred from the 1920's through the 1950's. A cursory review of case history in the area since incorporation indicates that there have been numerous variances granted in the past including front, side and rear setback variances, fence height variances, lot area variances and lot coverage variances. There are also properties in the immediate area which are nonconforming relative to use and parking. Staff finds that this criterion has been met. 3. The applicant is proposing a substantial investment in the property with this application, which would not be possible without the variance. This project represents substantial capital investment in the property which may not be cost effective or may require substantial redesign without the variances. Denver Water is the primary water provider in the metropolitan area; uninterrupted water service is expected by the citizenry and property owners. The proposed reconstruction will ensure continued provision of this service. Staff finds this criterion has been met. 4. The particular physical surrounding, shape or topographical condition of the specific property involved results in a particular and unique hardship (upon the owner) as SUP -12 -03 /Ashland Reservoir 8 distinguished from a mere inconvenience if the strict letter of the regulations were carried out. • Staff finds this criterion has been met. 5. The alleged difficulty or hardship has not been created by any person presently having an interest in the property. All structures deteriorate through time. The existing structure has been in place since the early 1900's. While upgrades and modifications have occurred ► on an off throughout the years, the threat of structural failure, while not eminent, is a fact that cannot be ignored. Reconstruction of the reservoir which is at the end of its useful life is being proactive rather than reactive. Staff finds this criterion has been met. 7. The unusual circumstances or conditions necessitating the variance request are present in the neighborhood and are not unique to the property. SUP- 12-0314shland Reservoir 9 8. Granting of the variance would result in a reasonable accommodation of a person with disabilities. Approval of the subject variances would not result in a reasonable accommodation of a person with disabilities. Staff finds that this criterion is not applicable. 9. The application is in substantial compliance with the applicable standards set forth in t Architectural and Site Design ManuaL I Many of the proposed improvements on the site are consistent with the goals identified in tile ASDM. Those would be increased pedestrian connectivity and upgraded landscaping. However, the proposed monitoring station is unattractive, is inconsistent with several building design standards and does not reflect the historical significance of the property. Staff finds that this criterion has not been met. 1. The special use will not have a detrimental effect upon the general health, welfare, safety and convenience of persons residing or working in the neighborhood. The convenience of the neighborhood will be disrupted with the construction which will take three years to complete. However, the public benefits of construction and the health, safety and welfare of the public outweigh the neighborhood inconvenience. Proper care must be taken by the applicant during construction to minimize negative impacts operations. Staff concludes that this criterion has been met. 2. The special use will not create or contribute to blight in the neighborhood by virtue of physical or operational characteristics. SUP- 12-03IAshland Reservoir 10 3. The special use will not create adverse impacts greater than allowed under existing zoning for the property. During construction there will be impacts to the adjacent neighborhoods. Once construction is completed, there will be little impact from the public utility use. Staff concludes that this criterion has been met. 4. The special use will not result in undue traffic congestion or traffic hazards, or unsafe parking, loading, service of internal traffic conflicts to the detriment of persons whether on or off the site. Parking accommodations for most employees will occur off-site which will reduce impact to the adjacent neighborhood streets. The approved haul routes focus primarily on state highways outside of the Wheat Ridge City limit lines. Construction trailer siting will be located on the northern portion of the site maintaining clear access on 30"' Avenue. Care must be taken by the contractor to maintain free access on other adjacent streets. The reservoir is a long-standing presence in the neighborhood and is generally a low traffic generator. Once the facility reconstruction is completed, there will be very minimal traffic generated by the site. Stqffconcludes that this criterion has been met. 5. The property is appropriately designed, including setbacks, heights, parking, bulk, buffering, screening and landscaping, so as to be in harmony and compatible with the character of the surrounding areas and neighborhood, especially with adjacent properties. Once completed, the property should have a positive impact on the neighborhood due to th increase in landscaped coverage, plant materials and reduction in impervious surface. Whil it is considered a public utility, which could be considered inconsistent with a residential neighborhood, the landscape treatments, including berms, mitigate the visual impact. I 6. The special use will not overburden the capacities of the existing streets, utilities, parks, schools and other public facilities and services. SUP -1 - t131AshIand Reservoir I I 7. There is a history of compliance by the applicant and/or property owner with Code requirements and prior conditions, if any, regarding the subject property. No history was found regarding code requirements or violation of prior conditions of approval on the subject property. Stiff concludes that this criterion has been met. 8. The application is in substantial compliance with the applicable standards set forth in the Architectural and Site Design Manual. Many of the proposed improvements on the site are consistent with the goals identified in the ASDM. Those would be increased pedestrian connectivity and upgraded landscaping. However, the proposed monitoring station is unattractive, is inconsistent with several building design standards and does not reflect the historical significance of the property. Staff finds that this criterion has not been met. ammulm A meeting for neighborhood input required by the SUP application was held on February 21, 2012. A summary of the meeting and attendance sheets are attached (Exhibit 4 and 5, neighborhood meeting re.cap and sign-up sheets). mm Referrals were sent to impacted agencies with responses below. City of Edgewater: Commented on potential traffic impacts and interruption of water serve. Applicant has met with Edgewater to discuss haul routes and roadway condition; documentation will be required. Xcel Energy: Owns and operates existing natural gas and electric distribution facilities in the project area which must be accommodated. Wheat Ridge Sanitation District: An existing sanitary sewer line on site must be abandoned. Piping plan upgrades have been added to the plan. Wheat Ridge Fire Protection District: Has requested advanced notice of any road closures during construction. An additional fire hydrant will be required at the northeast comer of Ingalls Street and W. 291b Avenue.

Wheat Ridge Public Works: Has reviewed drainage report and traffic mitigation plans. Has worked with applicant on the proposed IGA. Contacted but not responding: AT &T Broadband, Wheat Ridge Water District, Qwest Communications, CDOT and Wheat Ridge Building Division. MI Staff concludes that there are unique circumstances due to the quasi-public use and unusual site characteristics. The fact that the property is entrenched in a low-density residential neighborhood makes it particularly important that proposed traffic and construction impacts be mitigated. Staff concludes that once the structure is completed, there will be very little traffic generated by the site and there should be a substantial improvement in the aesthetics of the property. 7 negative impacts as posslbl For these reasons, staff is recommending approval of both the variances and the Special Use Pen recommended conditions listed in the Council Action Forrn.

That is still being worked out- they are. considering have parking at the Moffat station at 20' and Quail with shuttles running back andforth to the site. What will be the impact on the City's streets? All contractors working on the pro jecat must be licensed and bonded. Also, the City will enter into an IGA with Denver Water outlining construction resp There will be pre and post- construction inspections to ensure the streets are brought up to pre-construction conditions, I Will the project be phased? No. Why is the capacity of the tanks being reduced from 40 million gallons down to 20 million gallons? 20 million gallons ofcapacity is all they need at Ashland due to improvements elsewhere in the water delivery system, If the reservoirs are oversized and contain too much water there can be resultant water quality issues. There have been no water quality issues at Ashland due to active management by Denver Water to control the volume ofwater stored in the reservoirs. What will be the hours of operation for construction activity? Typically, 7 AM through 5 PM Monday through Friday. They may askfor extended hours based ♦ certain triggerpoints in the construction process such as during large concrete pours Jbr thefloor and lid. How will noise be mitigated? Most noise will occur during the demolition period. The demo on the first tank is expected to take about seven weeks. Once that is complete the work will take place below grade in the "hole ". Although Denver Water doesn't typically notify the neighbors regarding when the most noise will occur, there will be information on the construction schedule on Denver Water's website. How will storm drainage from the site be addressed? During the construction process silt fences and hay bales will be used to help control run-off. A new detention pond is being constructed at the southeast corner of the properly to serve as permanent detentionfior the site. Will Denver Water maintain the landscaping? Yes.

Dahl, City Attorney �SEAL� By: Robert J. Mahoney, Director of Engineering Legal Division W 111M a AMS-11 I MLIV V X EKKIA1 ki I By: James Lochhead, CEO/ Manager mo By: Auditor I City of Wheat Ridge - City Council September 10, 2012 Public Hearing — Ashland Tanks Background Information • History • Existing Site and Basins • Proposed Site Plan • Improvements Included in Project • Reduction in tank storage capacity from 40 million gallons to 20 million gallons, with a resulting reduction in the exposed tank roof area to approximately 60% of the existing exposed roof area. • Restoration of site grades closer to surrounding areas with resulting reduction in the size of exposed site retaining wall from approximately 1865 square feet to 270 square feet. • Install landscaping berms along the north side of the property for screening. • Replacement of the existing chain link fence with a more appealing ornamental metal security fence. • Dedication of property along W. 29` Ave. from Denver Water to City of Wheat Ridge to allow for their future re- alignment of W. 29 Ave. • Improve the site triangles at the Fenton St. intersections with W. 29` Ave. and W. 30`" Ave. • Right -of -way improvements along W.29"' Ave., W. 30`x Ave. and Fenton Street frontages with detached sidewalks and landscap outside the site perimeter fence. • Align the north entrance off of W. 30` Ave. with Gray St. • Increase in the amount of landscaped area on the site from less than 25% to approximately 50% and provide other landscaping improvements throughout the interior of the site. • Drainage improvements to the site including on -site detention. • Conveyance of Denver Water 42 -inch diameter Conduit No. 23 in W. 29` Ave. to City of Wheat Ridge for use as a storm sewer. • Photo Simulations • Construction Sequence to Maintain Facility Operations — Requires 4 -Year Project • Restricted Site for Construction — Requires Off -site Storage of Materials • Provisions Included to Minimize Impacts of Construction • Construction trailers south of curb -line along W. 30` Ave. with management and inspection parking along property on the south side of W. 30` Ave. • Minimize volume of on -site parking for construction personnel by arranging for additional off -site parking. • Protective barriers at south construction access • Established haul routes for truck traffic per City of Wheat Ridge requested routes. • Maintain south and west side berms where possible for portions of construction period in order to minimize noise, dust, etc. When berm areas need to be removed, install fencing with screening to minimize sound and dust. • Advance notice of construction operations and communication outreach with neighbors and the City of Wheat Ridge. Responses to Public Comments • Wheat Ridge Manor Care Center — 2920 Fenton Street o Ease of access to property during construction ➢ Construction personnel parking will not be allowed along Fenton Street. ➢ Use of Fenton Street by trucks will only be allowed on the four major concrete placement days for the floor and roof slabs of the tanks. Advance notifications will be given and signage provided. ➢ Construction work on Fenton will be limited to right -of -way improvements and abandoning of Conduit below street. ➢ Pipeline work at intersection of W. 29` Ave. and Fenton St. will require advance notifications and signage. • Ability for uninterrupted 24 -hour access for Emergency Responders ➢ Only street shut -downs will be for separate pipeline work at W. 29`' Ave., W. 30` Ave. and Fenton St. and advance notifications of specific detours will be given to City, neighborhood and Fire Department, and signage will be provided. • Disruption of services ➢ Disruptions of services are not anticipated. Where necessary, contractor will coordinate with the City of Wheat Ridge, who currently provides these services. • A pleasant living environment for the residents — concern for dust, noise, trash, debris and large volumes of truck traffic in the area ➢ Dust, noise, trash and debris will be minimized due to the fact that most of the construction activity will be below street grades in the tank excavation. Best management practices will also be used to control these items. ➢ The truck traffic will use designated haul routes which only include Fenton St. on the four main concrete placement dates. Advance notice and signage will be provided. • Projected 4 -year duration of project — timetable available? ➢ A summary of the project schedule is included in the SUP application. A more detailed projection of the schedule is available for review. Updates of the schedule will be provided during regular project meetings on site during construction. • Grout curtain for dealing with leaking gasoline tanks A grout curtain is a type of underground seepage cut -off wall, which may not be needed, depending on the volume of groundwater. • Pipeline work at W. 30` Ave. and Fenton St., south on Fenton St., east on W. 29` Ave. and construction of storm sewer improvements south on Gray St. Pipeline work will require advance notifications and signage. • Off -site storage of materials ➢ Excavated materials will be trucked to and from the YMCA site on W. 20` Ave. following designated truck haul routes. ➢ Construction materials will be trucked to the site generally as needed and will be staged on site. • On -site processing of demolished concrete ➢ Demolished concrete will not be processed on site. • Improved parking along west side of Fenton Street ➢ The west side of Fenton Street will be constructed in accordance with the standard City of Wheat Ridge street section requirements. 2 William "Bud" Starker — Wheat Ridge City Council • Desires brick piers along fence ➢ Brick piers will not be added due to concerns over security based on the possibility of climbing over or hiding behind these elements and the need for clear site lines along the fence for security cameras. The proposed ornamental metal security fence is the current standard security fence used by Denver Water in the interest of security, safety and protection of the public health. The new ornamental metal security fence will be a significant aesthetic improvement over the existing chain link fence. • Desires a perimeter concrete curb and gutter to confine the asphalt area at the south side of the property and protect the edge of the asphalt ➢ This asphalt area is not intended to be a parking lot, as will only be used as a turnaround a few times a year primarily for sediment removal and dechlorination trucks over the manholes along the tank drain line. • Largo Condo Association — 2890 Harlan Street • Any effect on 28 and Harlan Street ➢ Effects expected to be minimal due to the truck haul routes being directed to the east on W. 29 t11 Ave. However, there will likely be some construction noise and truck traffic will enter and exit from the construction access at W. 29 Ave. and Gray St. • Are there any plans to replace gas lines around W. 28 Ave. and Harlan St.? ➢ Gas line replacements around W.28 Ave. and Harlan St. are not part of this project, but may be a separate XCEL project. David Kueter and Dawn Kral - Kueter - 5837 West 29 "' Ave. o Concerns over noise, dust, truck traffic, and damage to property. Support leaving the existing hill on the south side of the property in place during reconstruction as a buffer. ➢ The existing berm on the south side of the property will be kept for the initial west basin demolition portion of the reconstruction, but then will need to be removed for access and staging of materials. When 'the berm area needs to be removed, fencing with screening will be installed to minimize sound and dust. ➢ The work area will be limited to areas north of the property line and the work will be controlled by best management practices. ➢ Pre - construction documentation of adjacent properties will be undertaken and vibrations monitored. There will only be post - construction documentation undertaken if the vibration measurements exceed threshold levels for concern. • Support limiting the work on the site to specific hours of the day, and restricting operations on weekends ➢ The City's restriction of weekday work hours to between 7:00 AM and 5:00 PM will be followed, with the exception of short preparation periods for the following weekend work. Weekend work will be limited to four periods where preparations for and installations of the large tank concrete slab placements will take place and to periods where make -up work becomes necessary.

At that time, open air reservoirs with earthen bottoms were located at the Site. In the 1910s and early 1920s, concrete floors and wood roofs were added to the reservoirs. In the mid 1960s and early 1970s, the wood roof was replaced with a precast concrete roofing system, Despite routine maintenance and significant repairs, the existing tanks have experienced leaks, and some of the precast roof sections have cracked. The tanks at this site have reached beyond the end of their useful life and continued repair to the existing structure is impractical.

The project is set to begin in Oc- tober and will be complete in the spring of 2oi5, according to Den- ver Water media relations special- ist Stacy Chesney. The two reservoirs, built in the 189os, have reached maximum use- fulness. Denver Water considers any continued repair impractical. Because a special -use permit from the city of Wheat Ridge is re- quired, a public hearing was held Feb. 21. According to Wheat Ridge Com- munity Development Director Ken Johnstone, between 20 and 30 residents attended the meeting. Denver Water community rela- tions specialist Joe Sloan said resi- dents asked about construction im- pact and the length of the project. He said, "It will take longer than most projects because we have to stage it for one tank at a time while the other tank remains in opera- tion." The new tanks will have a small- er footprint and the site will have a different appearance. There will be a larger landscaped area and the existing chain -link fence will be removed and replaced with a black, 8 -foot high ornamental steel fence. For information and to see the drawings and future landscape plans, go to www.denverwater .org/ashland. The first step will be to tear down one basin and build a new circular tank in its place. The first tank replacement is expected to be complete by February 2o14. Then the second tank will be torn down and a new one built. The two tanks can't be demolished at the same time because the water stored at the site is needed for customers and for fire protection. Since Denver Water is a public utility, the cost of the projects — $36 million — is funded by custom- ers paying for water rates and new tap fees. The biggest challenge for con- struction is the fact that it takes place in a residential area. Streets that will suffer the greatest disrup- tion are likely to be where pipes need to be installed in the roadway at 3oth Avenue and Fenton Streets. "We want to be good neighbors and are committed to working with the community to make sure the work is carried out as smooth- ly as possible," said Chesney. Wheat Ridge Manor Nursing Home is across the street. Chesney said, "We are discuss- ing with the contractor the best way to ensure access." When the reservoirs were built, open -air reservoirs with earthen bottoms were located at the site. In the igios and early 1920s, concrete floors and wood roofs were added. In the mid -196os and early 1970s, the wood roof was replaced with a precast concrete roofing system. Additionally, as improvements have been made to Denver Wa- ter's delivery system, it has been determined the existing 41 million gallons of storage at the site can be reduced to 20 million gallons.

Lindsay Pit Repairs to water tanks "a big deal" Denver Water's $120 million project is designed to fix eight huge underground reservoirs. By Bruce Finley The Denver Post LONE TRas» An armada of blue mix- ing trucks hooked up with orange pumping tubes Monday morning and spewed 1,300 cubic feet of wet, gray concrete into a huge hole in this thirsty suburb — lining a 10 million - gallon res- ervoir to be buried underground. It is the first of eight projects in a $ilo million rehabilitation of metro - area plumbing. Denver Water maintains at least 30 of these underground reservoirs, some holding as much as 25 million gallons, with the system storing 350 million gal- lons overall. The hidden tanks are a crucial part of making sure that clean water comes out when when 1.3 million Denver Wa- ter customers turn on their faucets — even if a pipeline ruptures or a water plant has to shut down. Paying the $12O million for the fixes over the next decade is expected to boost water bills, which already are in- creasing by about 5.5 percent a year. Denver Water officials said there is no way around the re- plumbing be- cause inspectors who went inside emp- tied reservoirs found enough cracks and infiltration to warrant repairs. "It's a big deal. We have to do it. This is the least intrusive we can get," said Denver Water's engineering director Robert Mahoney. "This eliminates the risk of us not getting our water." Next, the big trucks will move be- yond the suburbs at the southern edge WATER)) 36 Workers smooth the concrete for the base slab at Denver Water's Basin No. z, a 10 million - gallon underground res- ervoir in Lone Tree. Denver Water maintains at least 30 of these underground tanks. Kathryn Scott Osler, The Denver Post WATER: 135 trucks used in first tank repair A fleet of mix trucks spewed 1,300 cubic yards of concrete Monday for the base slab of Denver Water's new 10 million -gal- Ion reservoir in Lone Tree. The project is scheduled for completion in June.

Plan: Neighborhood Existing Site Conditions: The property is located on six (6) acres north of W. 29' Avenue, east of Fenton Street, and South of W. 30` ° ' Avenue, The parcel does not have an assigned street address. The property is zoned Residential -One. (R -1) and is almost entirely surrounded by residential neighborhoods. To the north and west are properties zoned Residential-Three (R-3). To the south is a single - fancily neighborhood zoned Residential-One C (R-IC). Across Fenton are properties zoned R-3, R-3A, and Con (C-1); these lots include the Wheat Ridge Manor Nursing Home, a gas station, and an auto repair shop. To the southwest across W. 29"' Avenue are properties outside the boundary of the City of Wheat Ridge in the City of Edgewater. The site contains Denver Water's Ashland Facility which includes two (2) underground reservoirs with a combined storage capacity of 41 million gallons of water (19 million and 22 million, respectively). The site has been home to a treated water facility since the late 1800's. A series of upgrades have occurred over the last 100 years, including the installation of a precast concrete roofing system in the 1970s. This roofing system exists today and covers much of the site. The elevation of W. 30 Avenue is nearly 20 feet higher than W, 29"' Avenue. Steep berms run along the south and west property lines, and a retaining , wall has been constructed along Fenton to address the topography of the site. A small well house is located on the south side of the property. A chain link fence surrounds the entire property, and the primary vehicular access point is fi - orn W. 30"' Avenue, The Ashland Facility is one of only as few reservoirs in the north end of the region. Ashland is primarily fed by Denver Water's Moffat Treatment Plant at W. 20"' Avenue and Quail Street. There is no pump station on the subject property; the water is transported by gravity flow cast to Denver, Applicant/Owner Preliminary Proposal: The applicant, Denver Water, is proposing to demolish the existing reservoirs and construct two concrete water tanks that are 256 feet in diameter. Each tank will accommodate 10 million gallons of water, they will be 28-30 feet deep, but only 1-2 feet will be visible above grade. The existing facility is deteriorating and has reached the end Of its useful life. In addition, the existing reservoirs provide excessive storage capacity, which combined with degradation has created water quality concerns. The replacement project is expected to begin construction in October 2012 and take approximately three (3) years to complete. In addition to replacing and downsizing the reservoirs, the redesign will reduce the amount of impervious surface, The basins will consume the northern two-thirds of the site and the southern portion will be landscaped to more gradually accon the change in elevation. A detention pond will be located at grade at the intersection of W. 29"' Avenue and Fenton. A parking area and unmanned water quality facility are also planned to be located on the W. 29"' Avenue frontage. The existing chain link fence is proposed to be replaced with a more decorative 8-foot high wrought-iron fence. Vehicular access to the water tanks will still come Iron W. 30"' Avenue, and a driving path will encircle the two basins. 'rhe project team is evaluating the feasibility of providing a hydropower facility on site somewhere along the north side of the property. Following the replacement oil - the basins, Denver Water also seeks to upgrade piping and drain lines within surrounding rights-of-way, including Gray Street, Fenton Street, and W. 29"' Avenue to Sheridan, kVill a neighborhood tnecting need to be held prior to application submittal? Yes. as neighborhood meeting will be required prior to submitting an application for a Special Use Permit. Planning comments: The following items were discussed based on the applicant's proposed development Special U'se Perinit fhe site is zoned Residential-One (R- I ), a zone district that provides for high quality, safe, quiet and stable low-density residential neighborhoods, and prohibits activities of any nature which are incornpatible with the low-density residential character, Qu asi -govern rnental uses are perri'litted in the R- I zone district, but quasi-governmental uses With outside storage require a Special Use permit. The Denver Water facility is considered as quasi-governmental use; but the water storage requires an SUP. A Special Use Permit is also required based On the scope of the excavation and fill operations, Per Municipal Code Section 26-623, any dumping, landfill, and/or extraction operation that exceeds I 20,000 cubic yards is allowed only by Special Use Permit. A Major Grading / ill Permit is issued upon and in conformance with the SUP, please see Public Works' comment section below. The two SUP requests can be processed simultaneously. 'rhe SUP process is described below, Consti-itetion LQgistics The City of Wheat Ridge does not regulate decibel levels specifically for construction prQJects. Section 16-103 of the City ("ode addresses "Unreasonable noise; Disturbing the Peace." This ordinance generally prohibits noise that is loud enough to bother others between the hours of 11:00 p.m. and 7:00 a.m. The performance standards associated with the Major Grading/Fill Permit include restrictions on hours of operations. Activities are permitted from 7:00 a.m. to 5:00 pm. and are prohibited on weekends and holidays. Restricted hours of operation for construction will likely be a condition of the Special Use Permit. CUITently, staffis unlikely to support an on-site concrete processing facility because of the associated noise and dust. This could be reconsidered if on-site processing will result in usable fill material and a significantly reduced number of truck trips, Staff anticipates neighborhood resistance to on-site processing, Cite CoilneilStlldy session Staff recommends that the applicant present this project at the August 2 "`r City Council Study Session. Plans may be conceptual in nature, but should include a general introduction to the scope, rationale, timeline, and impacts associated with the project. The council members of the City of Wheat Ridge have historically had close relationships with constituents, and it will be important to keep council members infra - med from an early stage. Staff has considered the applicant's wide fonnat images, and would prefer renderings that use images #829,#935,#J029,and#l040. If possible, image #1029 maybe more informative if taken from as point closer to the intersection of W. 29"' Avenue and Fenton, Development Stantim-ds The following development standards apply to non-residential uses in residential zone districts. Based on preliminary review of the site plan, the applicant may not be able to fully comply with all standards, The zoning code standards and references are listed below. As the applicant develops the site plan, variances may be discussed with staff, all variance requests will be processed with the SUP as needed. ['4n - king , & 1-laving Section 26- 501.E. of the zoning code requires areas subject to wheeled traffic for access, parking, or storage to be properly graded for drainage and surfaced with concrete, asphalt , or- brick pavers. The code does not include as variance from this requirement; the applicant may be able to request a waiver from City Council. Ifa waiver is considered, staff will likely recommend a minimum of 25 feet frorn the edge of street pavement into the site be hard Surfilced. I Section 26-5(')I,E.6 requires as 6-foot landscape buffer between parking areas and adjacent low- or medium- density residential uses. This will apply to the parking area on the south side of the site. Similarly, screening is required f"(,)r parking or loading areas between as structure and the right-of-way. P'encina &Landscalfing Staff requests that tencing is kept to a minimurn and landscaping is located between the street and fence wherever possible. Ali 8-foot high fence will require as variance front the 6-foot height nlaxinlurn for fences. This request will be incorporated into the SUP request and processed as a single application. A conceptual landscape plan will be required with the application for the Special Use Permit; a final landscape plan will accompany the building Permit application, The landscape plan should consider the following, per Section 26-502.1 .3: • Landscaping shall not be less than twenty percent of the gross lot area. • Private street trees are required for every 30 feet of street frontage, ornamentals are permitted • One (1) tree and ten (1(f) shrubs are required for every one thousand (1,000) square feet of required landscape area. • Nonresidential uses oil residentially zoned property require a minimum ten-foot landscape buffer adjacent to public streets abutting front or side yards. • All nonresidential uses located adjacent to residentially zoned areas or agriculturally zoned areas shall provide a screened or landscaped buffer area consisting of either or both of the following: (1) A six-toot high solid fence or landscaped hedge with a mature height of six (6) feet or (2) A strip of land at least fifteen ( 1 5) feet wide planted with as variety of'vegetatioll and a mininlurn density of one (1) shrub or tree per every two (2) linear feet of buffer area ad to the residential or agricultural zoned property.

Building Division coinments: The building division was not present at the meeting, but has the following comments: R The use tax rate in Wheat Ridge is equal to 3% and is usually assessed when the building permit is issued. Use tax is typically pre-paid in lieu of paying local sales tax oil construction materials at the time of purchase. Every person who obtains a permit must pay use tax oil materials used regardless of their tax exempt status, per Section 22-68 of the Municipal Code. Building permit fees are based on project valuation, and use tax is typically based on 3 1% of'60%) of tile project valuation. For questions related to use tax, please contact the 'fax and Licensing Division (303 For question related to project valuation, please contact the Building Division (303-235-2855), Public Works comments: Public Works was present at the meeting and has the following continents: Haid Routes Haul routes will need to be a continued point ot'discussion with the Public Works Department. West 29"' Avenue is a collector street, and is scheduled to be repaved between the subject property and Wadsworth prior to the replacement prO.Ject. For this reason, this section of roadway west of the site will not be permitted to be used as a haul route; haul routes will need to go cast. Public Works will consider use of Fenton Street at the applicant's request. Use of the old Ford Site for staging or storage will not be supported by staff. The paved and unpaved parcels at the southwest intersection of Wadsworth and W. 38"' Avenue, are together considered one of the City's highest priorities for redevelopment. 'rhe city is actively working with property owners and potential developers who have expressed an interest in assembling and/or developing the area. R�( glit I)cdic ation 'file pro will require a right-of-way dedication at the south end of the site along W. 29"' Avenue. ,ject The resulting right-of-way width will need to be 61 feet wide to accommodate a standard street section with sidewalk and arrienity zone. "I"he dedication rriay be conveyed by deed. Staff prefers realignment option two, whereby improvements on 29"' Avenue are symmetrical. flublic IIIIJ)rovetnents As Part of the basin replacement project, public improvements around the site Should include a detached sidewalk and tree lawn on Fenton Street and W. 30"' Avenue. West 29"' Avenue is a collector street, so the Streetscape Design Manual (SDM, attached) applies to this portion or roadway. Please refer to tile street sections distributed at the inceting and to Chapter 3 of the SDM for design standards and guidelines. Restoration of other surrounding streets due to darnage or pipe replacement will need to be further discussed with the Public Works Department. The City's goal is to achieve full street sections in this neighborhood. PIcase note that per Section 26-502, all property owners in the City are responsible for maintenance of landscaping within tile, portion of the public right-of-way between the back of the curb or street pavement and adjacent private property. The vehicular entrance off W. 30"' Avenue will need to be moved. Two options include: A) to the west, to align with Gray Street, or M B) to the cast, to be located mid-block, ,41c or Graz fing/"ill Permit Dumping, landfill and/or extraction operations which exceed twenty thousand (20,000) Cubic yards is allowed only by Special Use Permit (see process above). A Major Grading/Fill Permit may be issued upon and in conformance with a Special Use Permit.

Denver Water Ashland Reservoir Replacement Project Ladies and Gentlemen: Denver Water is pleased to submit this letter regarding the Ashland Reservoir Replacement Project. This is an important project for Denver Water and its customers in the surrounding community. This letter includes a brief description of the site and the project. lZman; t . S A * 0 U The reservoirs at this site have reached beyond the end of their useful life and continued repair of the existing structures is impractical, Additionally, it has been determined that the existing 41 million gallons (MG) of storage is too large and can be reduced to 20 MG. Too much storage in a reservoir can also cause water quality concerns because it sits too long. CwOSERVE' The primary component of this project is the demolition of the existing reservoirs and construction of two 256 foot diameter concrete water tanks. See attachment for proposed tank layout. Additional project components are listed below: Successful completion of this project will require that a number of challenges be dealt with. Many of these challenges stem from the age of the reservoirs, proximity to residents, and lack of construction and staging areas, A list of items to consider is presented below: 151M �31 • Other Ls�urrourjdin i!9S—LQ&C o D nve , M U a yj��L! Ljog, Impact to traffic depending on routes chosen for hauling of material to and from the site, • Resident5l NursjDg_flome surrou _q_ttg� �te '4fl-(k Q o Visual impact of improvements. ,-- Construction impact -- noise, dust, trash, safety, * Impact to traffic, parking or access to their homes. * 24 hour access by emergency vehicles to Nursing Honne, Up to date information on the project during construction The use of a grout curtain to provide a barrier between contaminated groundwater and the tank excavation will be considered, This could solve the problem of pulling contaminated groundwater onto the Ashland site however; contaminated soil and groundwater may still be encountered with any off-site transmission main improvements. �Xisti,ng.-In, Sealants in the floor/wall interface and around the perimeter of the columns have tested positive for asbestos. These sealants will be quantified and required handling and disposal requirements will be prepared, MUM The design, public comment and permitting period is scheduled to last approximately 17 months beginning in April, 2011. Construction for this project is estimated at 36 months beginning in Fall of 2012, We appreciate your consideration and look forward to meeting with you to discuss this important project.

The revised SUP sections should replace and supersede sections in the original SUP submittal dated April 10, 2012 and sections in the first resubmittal dated July 5, 2012. Per discussions with COWR staff, the comments related to the Land Survey Plat and the Right - of -Way Deed will be addressed at a later time after Denver Water Board approval. These items will be submitted separately. The drainage report has been revised per the COWR comments. The changes include corrections to the orifice diameter and revisions to the Summary Runoff table in Appendix A. Due to new survey data, received after the first resubmittal of the SUP, the "Modification to Existing Storm Sewer" section (pages 9 and 10 of the drainage report) has been revised from the first resubmittal. The associated drawing in Appendix F was also revised to reflect the changes. Section M in the SUP submittal document has been revised to encompass the comments made by COWR in relation to traffic mitigation. The changes to Section M include revised exhibits showing the use of the W. 301h Ave. right-of-way for the trailer area, revised exhibits for haul routes and a revised Ashland Truck Traffic spreadsheet. One CD-ROM with the revised SUP Application is also included.

Hendricks(15)westernsummit com; martin.garcia(a)denverwater org; genesCaDsdgdenver.com; BGoetz(abtstinfrastructure.com Subject: Denver Water Ashland Reservoir Tank Replacements Western Summit (WSCI) is planning to begin submittal of the necessary permits for the above referenced project soon. I would like to verify the City of Wheat Ridge permit process per our discussion yesterday. A few questions occurred to me since our conversation which I have highlighted in yellow. CDPHE PERMITS WSCI has already applied to CDPHE for the CDPS (remediation activities discharging to surface water COG315) and the Land Development APEN/Application for Construction Permit. We expect both of those permits to be issued within the next few weeks. Belfor Environmental (as a licensed asbestos abatement contractor) has applied for and received the CDPHE Asbestos Notice for the west tank. This notice will be transferred to the successful abatement contractor. WSCI will make the CDPHE Demolition Notification Application after the final air clearance has been received. A separate asbestos notice & final air clearance will be necessary for the east tank in approximately two years as asbestos abatement of that tank cannot occur until the new west tank is complete and in service. The stormwater discharge permit (COR03) has not been applied for yet. CDOT PERMITS WSCI or the applicable subcontractor will apply for the ROW Permit required for Conduit 23 work at 29`h & Sheridan. COWR PERMITS No permit applications can be made until the Special Use Permit & Intergovernmental Agreements are approved. Any business entity (whe--r contractors or subcontractors) must have a COWR license. Electrical contractors must have a COWR registration. WSCI has applied for a COWR license. Asbestos The COWR does not require a permit for the asbestos abatement. In order to apply for the demolition permit, a copy of the final air clearance report must be included with the permit application. (This is the same requirement for CDPHE's demolition notification application). Currently the asbestos abatement work is scheduled to be completed by November 21, 2012. Final air clearance should be received by the end of November 2012. Demolition work is scheduled to begin in March 2013. Demolition There is no separate application for the demolition permit (it is the same application as for the building permit). There is a flat fee of $50 for a demolition permit. A demolition permit will not be issued without the asbestos air clearance, CDPS storm water permit & storm water management plan (SWMP). Since the city will need to review & approve the permit & plan before issuing the demolition permit, can you give me an estimated duration required for that review process? A separate demolition permit must be obtained from the Wheat Ridge Fire Protection District. WSCI is in contact with WRFPD regarding this permit. Building 1. A building permit will not be issued without the CDPS storm water permit & SWMP. 2. The demolition permit can be combined with the building permit. 3. A building permit is not required for the construction trailers. 4. No grading permit is required. S. A separate building permit must be obtained from the Wheat Ridge Fire Protection District. 6. Since the city will need to review & approve the plans before issuing the building permit, can you give me an estimated duration required for that review process? ROW Use/Construction A ROW use permit is required for the construction trailers (an oversize/overweight permit may also be required). A ROW use permit is not required for the Conduit 1/17 interconnect vault. Each occurrence of work within the ROW requires a ROW Construction permit. Each permit requires an estimate for that work and a bond in the amount of 125% of that estimate. Miscellaneous 1. No connections are anticipated to Wheat Ridge Water District facilities. Therefore, no plans have been submitted to them & no permit is required. 2. A connection will be made to Wheat Ridge Sanitation District. Plans have been submitted to them and a permit is required. 3. A connection will be made to Wheat Ridge Storm Drain. Is this connection covered by the ROW Construction permit, the building permit or is something else required? Thanks very much for your help.

Denver Water 1600 West 12`h Avenue Denver, CO 80204-3412 Dear Mr. Garcia: Wheat Ridge, CO 80033-8001 P: 303.235.2846 F: 303.235.2857 This letter is in regard to your first resubmittal for approval of a Special Use Permit with variances to allow reconstruction of the Denver Water Ashland Reservoir facility in an R-1 zone at 2901 Fenton Street. I have reviewed the first resubmittal and have the following comments: I . All previous planning comments have been addressed. 2. The consolidation plat included in the resubmittal package dated July 5, 2012 has not been previously discussed. In order to formally acknowledge this part of the land entitlement package, please submit a separate land use application for the consolidation plat with a fee of $300. See the attached checklist which itemizes the required technical submitted items. The consolidation plat will be processed administratively. Your resubmittal was sent out for referral and the following are comments received: Wheat Ridge Fire Protection: District: See attached correspondence from Kelly Brooks to Adam Monchak dated July 19, 2012. Wheat Ridge Public Works: See attached comments from Dave Brossman dated August 2, 2011. This case is currently undergoing administrative noticing whereby the comment period ends at 5:00 PM on August 6, 2012. If no legitimate objections are received, the application can be approved administratively by the Director of Community Development. If legitimate objections are received or if it is determined that the SUP criteria have not been met, this case will be scheduled for public hearing in front of City Council. The date being targeted if that should happen is August 27, 2012 at 7 P.M. In preparation for the public hearing, I will need an electronic copy of the legal description in Word format no later than August 8. This can be emailed directly to me at mreckert(&,ci.wheatridge.co.us. In addition, the property will have to be posted for the August 27 public hearing by August 13.

Monchak, P.E. TST Infrastructure, LLC. 61 Inverness Drive East, Suite 100 Englewood, CO 80112 303.799.5197 Wheat Ridge, CO 80033-8001 P: 303.235.2861 F: 303.235.2857 Re: Second Review Comments of the ROW Deed for W. 29"' Ave., Final Drainage Report/Plan, Site Plans, and Special Use Permit Application for the Ashland Reservoir Tank Replacement Project located at 2901 Fenton Street. Dear Mr. Monchak, I have completed the second review of the above referenced documents received on July 6, 2012, and I have the following comments: LAND SURVEYING Land Survey Plat: 1. I suggest this plat be renamed "Ashland Consolidation". This better describes what is being accomplished by this document and will help the Jefferson County Clerk & Recorder's office process it properly (it will be processed as a Consolidation as opposed to a Land Survey, which for future archival searches will be important). 2. In addition, if the intent is to consolidate the current two individual parcels into one as stated in Note 1, you will need to be sure to clearly show the boundary lines as "LOT LINES HEREBY REMOVED BY THIS PLAT". Otherwise the parcels will remain separate and distinct and the County will not recognize it as a single parcel. Right -of -Way Deed: 1. Exhibit A: The City of Wheat Ridge uses a modified, ground-based form of the NAD83/92 State Plane coordinate system. The Basis of Bearings will need to be modified to read "NAD 83/92" or "NAD 83 HARN" on the second page of Exhibit A (please refer to the redlined Exhibit). 2. With this letter I've include a Warranty Deed in Word document format for the Right -of -Way dedication along West 291h Avenue. I have completed everything on the deed except for the name and title of the Denver Water representative and the Notary Public name and address. I highlighted these items so that they can easily be seen and completed. CIVIL ENGINEERING DRAINAGE Final Drainage Report (Discussion): 1. All previous comments have been addressed; the discussion portion of the Report is approvable. www.d.wheatridge.co.us Public Works Engineering July 27, 2012 Page 2 Final Drainage Report (Appendices C - E): 1. In Appendix D, on Worksheet Y, the orifice plate drill holes are stated to be 0.875" (or 7/811), while the detail on the Drainage Plan shows the orifices as being 13/16" in diameter; please be sure these correspond to one another. Final Drainage Plan (Appendix A): 1. The report states (on Worksheet Y) that the WQ orifice drill holes are 7/8" diameter, while the detail (Section G) on Sheet 3 of the Stormwater details shows them to be 13/16" in diameter. Please be sure these correspond to one another. 2. The contributing sub -basins for design points N and O appear to be switched on the Summary Runoff Table. CONSTRUCTION TRAFFIC Traffic Mitigation: (per Russ Higgins, Field Services Supervisor) 1. All Traffic control plans will need approved by Public Works prior to any work. 2. 30°i Ave. between Sheridan and Fenton cannot be used as any type of haul or delivery route for the project. 3. The use 30"' Ave. between Harlan and Fenton will be noted in the IGA. 4. Haul Route 1 Option C needs revised as the City will not allow any construction traffic on 32nd Ave. from Wadsworth to Sheridan (except as noted on Route 3 Option C for 5 days only). The return route needs to remain on 20t1' Ave. to Sheridan north to 29°i and west to the site. The other option is to go north on Wadsworth to 44°i Ave. east to Sheridan and south to 29th. (38"' Ave. cannot be used as a haul route.) 1. Haul Route 2 Option C is OK. 2. Haul Route 3 Option A is OK. 3. Haul Route 3 Option C needs to be modified — Loaded Redimix trucks should enter from 29°i Ave. to Fenton north to 30"' - Empty Redimix trucks shall exit west on 30th north on Harlan and west on 32nd Ave. This route is only allowed for a maximum of 5 days to accommodate the deck and slab pours utilizing a concrete pump truck on 30th Ave. 4. The city will require extensive use of variable message boards to notify the traveling public of upcoming closures, detours and traffic impacts on various streets. Environmental Mitigation: 1. The City will review a Stormwater Management Plan when it becomes available. www.ci.wheatridge.co.us Ashland Reservoir -2901 Fenton St_ROW Deed -FDR -SUP review2.ltr.docx Public Works Engineering July 27, 2012 Page 3 OTHER REOUIREMENTS: 1.

TST Infrastructure, LLC 61 Inverness Dr East, Suite 100 Englewood, CO 80112 RE: SUP -12-03 /Ashland Reservoir Mr. Monchak, I provided comments in response to the City of Wheat Ridge Community Development Referral on behalf of the Wheat Ridge Fire Protection District. Comment #4 required a fire hydrant be added on W 291" Avenue: 4. One additional fire hydrant will be required along 291h Avenue in order to meet water supply distance requirements. Any required hydrant(s) shall be in place prior to new construction on the project site. A fire hydrant located in the immediate vicinity of the intersection of 291" Avenue and Ingalls Street, as proposed, would meet the water supply distribution requirements of the Fire District and would satisfy comment #4 of the Community Development Referral comments.

Section B: In the letter of request, please be more specific regarding the variation from permitted construction days and hours. This should relate back to the anticipated construction schedule and the four construction Vim ilestones"when work days and hours will exceed the City's standard. The Letter of Intent and Purpose has been modified to be more specific regarding the variation from permitted construction days and hours and will reference the anticipated construction schedule in Section E and the Street Impacts and Truck Traffic summary sheets in Section M. The dates of the large concrete placements has been listed as approximate time periods at this time due to the fact that these placements cannot be scheduled until the work progresses to a point closer to these placements. As the dates of these placements are scheduled, city staff and property owners adjacent to the site can be updated with a more accurate date for each placement. ,,Z. Section C: In the responses to the SUP evaluation criteria, #3., expand discussion about the construction impacts and how these will be mitigated. The response to #3 of the SUP Evaluation Criteria has been revised to include discussion about the construction impacts (as well as the permanent impacts) and how they will be mitigated. Reference will also be made to the Special Use Mitigation and Ashland Tanks Street Impacts summary sheets in Section M. Section C: In the responses to the SUP evaluation criteria, #4, discuss construction parking. The response to #4 of the SUP Evaluation Criteria has been revised to include discussion about construction parking. Reference will also be made to the Special Use Mitigation, 301h Avenue Construction Trailers and Ashland Tanks Street Impacts summary sheets in Section M. Section C: In the responses to the SUP evaluation criteria, #6, discuss construction traffic and proposed mitigation. The response to #6 of the SUP Evaluation Criteria has been revised to include discussion about construction traffic. Reference will also be made to the Special Use Page 1 of 20 Mitigation, the Ashland Tanks Street Impacts, and the Ashland Tanks Truck Traffic summary sheets in Section M. l5: Section D: In the responses to the variance evaluation criteria, A, be more specific regarding the need for variance from permitted construction days and hours. The response to Item A of the Variance Evaluation Criteria has been revised to be more specific regarding the need for variance from permitted construction days and hours. Reference will also be made to the anticipated construction schedule in Section E, and the Ashland Tanks Street Impacts and the Ashland Tanks Truck Traffic summary %sheets in Section M. W Section D: In the responses to the variance evaluation criteria, D, address the grades relative to the surrounding properties and challenges as a result (topographic conditions). A response to Item D of the Variance Evaluation Criteria has been added to address the grades relative to the surrounding properties and challenges as a result. ,?/Section D: In the responses to the variance evaluation criteria, E, please address hardship. A response to Item E of the Variance Evaluation Criteria has been added to address grades hardship discussed in item E. �. Section E, please modify the construction activities to highlight the four critical construction points that require the longer days and hours. In the summary schedule, the program being used is not set up to highlight only a few of the individual construction tasks. The large concrete slab placements are included, along with many other tasks, within the Tank 2 and Tank 1 Construction items. See Item 1 above regarding the need to schedule these dates when the construction work gets closer to preparations for these large concrete placements. The Special Use Mitigation, Ashland Tanks Street Impacts and Truck Traffic summary sheets all reference these concrete placements. 9. Section M: In the Traffic Impact Table, are the bolded dates, the four critical construction points? Please clarify with notes. No, the bold dates are milestone dates, but the four critical concrete placements has been added to the Ashland Tanks Street Impacts table with approximate dates following each "Begin Construction" milestone. The Ashland Tanks Truck Traffic summary sheet also references these concrete placements. See Item 1 above regarding the need to schedule these dates when the construction work gets closer to preparations for these large concrete placements. Page 2 of 20 PLAN SET SHEET 1 (DECLARATION SHEET) 1. A site plan for SUP approval is not typically recorded. If you do want to record it, the following modifications will be required: Add a legal description, modify the Jefferson County Clerk and Recorder's certificate to their standard signature/recording block, and designate who will be signing as the property owner with proper notary attestation block. Denver Water has determined the Site Plan Review Set will not be recorded at this time. The title blocks on the declaration sheet associated with recording the site plan has been removed. 2. Modify the City Council signature block to read as follows: Approved this day of , , by the City of Wheat Ridge City Council". The City Council signature block has been revised to match the wording above. 3. Add a case history box with the following case number: SUP -12- 03. Case Number has been added. 4. The final photometric plans need to be incorporated into the review plan set. The sheet numbers need to be numbered accordingly with the first sheet being 1 of 12 (or whatever this total sheet numbers will be). The renderings will not be recorded. The photometric plans have been incorporated into the review plan set and renumbered accordingly. It is noted that the renderings will not be in the review plan set and have been separated. SHEET 2 (EXISTING SITE PLAN) 1. Renumber the sheet number accordingly. Renumbering has been completed. SHEET 3 (PROPOSED SITE PLAN) 1. Renumber the sheet number accordingly. Renumbering has been completed. 2. In the drawing, on the southern portion of Fenton Street, there is a meander in the sidewalk. What is this obstruction? Please identify. The sidewalk meander is due to an overhead electric (OHE) power pole. Per COWR comments all sidewalk meanders have been removed. 3. In the development standards chart, indicate number of parking spaces for Page 3 of 20 service vehicles on the southern pull -in from W. 29"' Avenue. No parking spaces will be provided. This access is to perform maintenance as required on the facilities at the southern end of the site (Drainage Facilities, and manholes on the tank drain line.) There are two manholes that will periodically need to be serviced by a truck with a large trailer. The area at the south end of the site will provide adequate area for the truck to maneuver the trailer into place and turn around to exit the site without backing out on to West 29"' Avenue. SHEET 4 (LANDSCAPING PLAN) 1. Renumber the sheet number accordingly. Renumbering has been completed. 2. The number of street trees required at a 1/35' ratio appears adequate in number and for species with one exception. On the drawing at the northwest corner of the property, six American Compact Cranberry bushes (ACC) are shown. These are shrubs and need to be replaced with acceptable street trees. Northwest trees are Purple -Leaf Mayday trees, typo has been corrected 3. The number of additional trees and shrubs required is inadequate. Per Section 26-502 of the zoning and development code, one additional tree and ten shrubs are required for every 1000 square feet of required landscaped area. My calculations indicate that only 42 additional trees are provided where 72 are required. The required shrub count is for 720 shrubs where 541 shrubs are provided. Please modify the landscape plan (all sheets) to meet these minimums. Trees has been added to the plan to meet the required 72 within our property line. Total for 90% submittal= 72. Karl Foerster grasses were acceptable to CO WR toward the shrub count. Total for 90% submittal=738(720 required). 4. Add the following note: All landscaped areas shall be served by a fully automatic, zoned irrigation system. Irrigation note has been added. 5. Add the following note: Proposed native grass seed mix variety and application shall be approved by the City of Wheat Ridge. Native seed mix has been put on the drawing. Seed Specification will be supplied to COWR for review. PHOTOMETRIC PLAN SET The photometric plan set will eventually need to be incorporated into the plan review set for public hearing and recording. The renderings will not be recorded. Page 4 of 20 Photometric drawings have been included in the plan set. The interim construction site lighting along West 29th and 30th Avenues is not in conformance with the City's standards for exterior lighting. Although this is considered interim construction lighting, the three year timeframe for project completion will have tremendous impacts on the adjacent low density neighborhood. Therefore, staff will not support the interim lighting plan as submitted. Denver Water will not have any lighting on 291h Ave. The light shown on 301`' Ave is needed for access to the site and security. Additionally, this light is needed for safety to help southbound drivers on Gray St. realize that Gray St. ends at W 30th Ave and doesn't confuse the site entrance with a continuation of the road. This light will not shine above the horizontal plane. 3. The final site lighting along West 291h and 301h Avenues is not in conformance with the City's standards for exterior lighting. See the previous response (Item #2). OTHER ITEMS: 1. Staff highly recommends that the perimeter fencing be upgraded to include brick pillars evenly spaced at 100' intervals adjacent to street rights-of-way. DW has determined that the fence posts has been revised to include an ornamental top to improve the aesthetics of the fence. DW has also provided a letter stating the concerns with the brick pillars. The letter is attached. 2. As construction parking will not be allowed in the West 301h Avenue right-of-way, Staff would suggest that area churches be contacted to see if they would allow construction parking. There are two churches in the immediate vicinity at 6475 W. 29th Avenue and 630 W. 291h Avenue. Another suggestion would be to build a temporary lot on the vacant property located just to the southwest of the reservoir. This property is located in the City of Edgewater. The proposed use for West 30th Avenue has been revised and is reflected in the exhibit for West 30th Avenue Use under tab M of the SUP submittal package. Page 5 of 20 Comments from City of Edgewater, Comments made by Brea Pafford; May 3, 2012 Overall Comments: 1. What is the anticipated impact traffic on Sheridan, 26th & 20th? If it is a large impact, is there any way to mitigate it? See spreadsheet "Ashland Tanks Truck Traffic" and proposed haul routes #1C, 2C, 3A & 3C. These are the routes determined in meetings with the City of Wheat Ridge, with a couple of modifications in order to obtain right turns for trucks. The City of Wheat Ridge has indicated that documentation of roadway conditions prior to the project in order to be able to assess damages caused by construction traffic is desired. DW and City of Edgewater have met to discuss the project and review these routes and City of Edgewater has also indicated that roadway condition documentation prior to the project in order be able to assess damages caused by construction traffic would be the preferred method. It is the intent to not document Sheridan Blvd. and Wadsworth Blvd., since these are State Highways that should be designed for these types of truck traffic. 2. Will there be any interruption of service to Edgewater? No service interruptions are anticipated. If this changes, the outages will be scheduled with Edgewater. 3. Will Edgewater public works need to be involved with the project? Currently we do not anticipate that Edgewater public works will need to be involved with the project. If plan review or another items comes up that requires Edgewater public works to be involved this will be scheduled with Edgewater. Comments from City of Wheat Ridge Police Department Comments made by Kevin Armstrong; April 18 2012 Note: Police Department sees no concern with the request. No comments given. Page 6 of 20 Comments from City of Wheat Ridge Sanitation District Comments made by Bill Willis; April 23 2012 Overall Comments: The proposed site plan does not indicate what is being proposed for the onsite private sanitary sewer line shown on the existing site plan sheet (extension for connection to new facilities, abandonment, etc.). If this existing sanitary sewer line is to be abandoned, it should be disconnected at the mainline. A note has been added to the site plan. The sanitary sewer line is currently abandoned in place. Provisions will be added to the construction drawings to disconnect the sanitary sewer from the main line. It does not appear any replacement/ installation of the inlet or outlet lines planned for the new water tank reservoir will affect the existing sanitary sewer mainlines in the repair area. However, if this is not the case, please be aware if any vertical clearance requirement cannot be met, accepted practices such as encasement and insulation between utilities shall be provided. If any vertical clearance between the sanitary sewer and a crossing of the inlet or outlet lines are closer that the CDPHE requirements, the encasement will be provided as part of the project scope. The yard piping plans have also been included in the site plan review document to show the location of the proposed pipelines. 3. Please provide a submittal for piping upgrades (inlets/outlets) if elevation, size or alignment plan to be modified. Piping plan sheets have been added to the review plan set to show the alignment of the inlet and outlet piping and the addition of the sanitary sewer at the north end of the site, which will connect to the sanitary sewer in West 30"' Avenue. 4. 291' Street Realignment- If any adjustments to manhole rims are necessary during the realignment/work to occur at West 29"' Avenue and Gray Street intersection, these adjustments should be included as part of the contractor's scope. Any adjustments to manhole rims will be included with the West 29t" Avenue Realignment project. Page 7 of 20 Comments from City of Wheat Ridge Public Works Comments made by David Brossman• April 27 2012 Land Surveying -Right -of -Way Deed The City of Wheat Ridge requires all plats and dedications to include tie(s) to section or quarter- comers on only (aliquot comers are not acceptable for use in section ties). To complete the section -tie in the Legal Description, please provide the distance from the Point of Commencement (Center Quarter -Comer, Section 25) to the southwest comer of the northwest quarter of the southeast quarter (center - south sixteenth comer) of Section 25. The Legal Description has been revised to include the section comer. 2. Include the above-mentioned distance on the graphical portion of the Exhibit A. The Legal Description has been revised to include the section corner with distance included in the exhibit. 3. Modified Type 3A ADA ramps are required at W. 29th Ave. & Fenton St. and W. 30th Ave. & Fenton St. Depending on how the required ramps fit a small comer of ROW may need to be deeded to the City for future maintenance of the ramps (please refer to comment 1 for the Site Plan). The ROW has been adjusted as required after the ADA ramps were included in the Site Plan. Civil Engineering -Final Drainage Report (Discussion): Under II. B of the Historic Drainage System section of the Report, please discuss the historical sub- basins, their respective areas, discharge points, and Q 5 & Q100 for each sub -basin. The discussion seems to indicate at least 3 sub -basins. This information can then be utilized in the Conclusion section to compare with the proposed design in support of statements made that the proposed design does in fact improve the site drainage conditions and lowers the impacts to downstream stormsystems and properties. Discussion of the historic drainage system has been added to the this section 2. Under Section III. B. Runoff: a. Provide information regarding the sub -basin design point locations and release rates for the minor and major events at each DP. Information for each sub -basin design point release rates has been added. b. Discuss the flow proposed for release from sub -basin 2 into W. 30th Avenue, and demonstrate the capacity of the existing storm Page 8 of 20 sewer and inlet is sufficient to handle the additional runoff. Please note that from the City's GIS the area that appears to drain into the existing W. 30tt' Avenue storm sewer is at least 1.388 acres. Discussion has been added to this section and the area has been revised to the 1.388 acres. c. It appears that sub -basin 10 flows directly onto W. 29th Avenue. The impact of this flow needs to be discussed. It also appears that most of the paved area in this sub -basin is above the water elevation in the EDB, so an inlet and pipe could be added that would convey the runoff to the EDB. The flow onto West 29"' Avenue has been discussed and an inlet and pipe for the paved area has been added. d. Rather than having statements that "anticipate" various results, a table comparing the existing and proposed flows at the various discharge locations should be included. A table comparing the existing and proposed flows has been added. Under Section III. C. Detention: a. The discharge rates for the WQCV should be based on the 40 -hr release rate. We allow the 24 -hr rate for very small sites. The minor and major storm release rates should be based on Table SO -1, not on the WQ drain times. The WQCV discharge rates has been revised to use the 40 -hr release rate and table SO -1 has been used for the minor and major storm release rates. b. It is stated that the EDB spillway will be located on the west side and sized for the "tank overflow scenario". It appears in the event of a catastrophic "tank overflow" event the water flow down Gray Street, crossing W. 26th Avenue and into the City of Edgewater. In light of this "scenario", please discuss the downstream impacts under this scenario and provide calculations for Gray Street and a couple of cross-sections depicting the anticipated flow depth at those locations under the "tank overflow" condition. All flows should be stated in "cfs" for ease of comparison. Gray Street capacity calculations and anticipated flow depth cross sections have been added. Discussion will be added to this section about downstream impacts. c. Looking at the contours downstream of the proposed overflow spillway, it appears that there may be potential liability for Denver Water under the "tank overflow" scenario, and as such the City of Wheat Ridge strongly recommends Denver Water provide this Page 9 of 20 design to the City of Edgewater for their approval. The overflow scenario has been evaluated to consider the surrounding community. The most effect method has been used to convey the water in the event of an overflow while still attempting to minimize the impacts to the surrounding community. City of Edgewater will be provided a copy of the drainage report for review. 4. Under Section III. F. Open Channel Flow, Please describe where the channel running along the easterly edge of sub -basin 9 flows to (i.e., into the detention facility, to Fenton St., etc). The channel flows to the EDB. Clarification has been added to this section. 5. Under Conclusions: a. Section A. Impact of Improvements. While it is acknowledged that the proposed design reduces the overall site imperviousness, please provide a comparison between the historical conditions and Q's with the proposed design and values. The existing and proposed flow table has been added to compare the values. b. Discuss the benefits of the present design over the existing conditions and the impacts to downstream properties and storm systems. Discussion of the proposed design has been added to this section. c. Section B. Compliance with Applicable Criteria. In the third sentence of the third paragraph it is stated that "The estimated depth at the 6 inch curb ... will be 5.16 inches." Later on flow spread and velocity is also discussed. Please define what roadway(s) this paragraph is referring to (this project is bounded by three roadways, with existing 6" vertical curbing along two of them). This is referring to the West 301h Avenue. Clarification has been added to this section. d. A comparison between the historic runoff quantities versus the proposed developed runoff Q's should be included in this section. The discussion has been added to compare the values. Final Drainage Report (Appendices C - E): 1. Worksheet A needs to be divided into the various sub -basins for the existing conditions. The existing site has been divided into sub -basins and worksheet A has been revised. Page 10 of 20 2. On Worksheet L, the following corrections should be made: a. The initial/overland time is based on sheet flow conditions. The maximum length is 300 feet in urban watersheds. As soon as the flow is concentrated in Swale, gutters, etc. then the travel time should be used. The overland time has been revised and the travel time has been adjusted accordingly. b. The minimum Tc for urban watersheds is 5 minutes. The equation used in the Tc check is the maximum T, that should be used, not the minimum. The time of concentration has been revised to a minimum of 5 minutes and the time of concentration check equation has been revised to use the maximum. 3. On Worksheets M and N, the routing of the flows through the storm sewer system has not been done properly. The flow routing has been revised so that the flow is totaled. as is flow through the storm sewer system. 4. On Worksheet N, the Q,00 and contributing areas do not match the Summary Runoff Table found under the Proposed Drainage System on the Proposed Stormwater Site Plan. The values from the Proposed Drainage System has been updated on the Site Plan after the revisions from item 3 above have been completed. 5. On Worksheet 0, the following corrections should be made: a. Only the tributary area for the EDB should be used to size the WQCV and the detention volumes. The areas have been revised to remove the areas that are not tributary to the EDB. b. As noted earlier, only the 40 -hr release rate calculations should be used. 40 -hr release rates have been used and the calculation has been revised accordingly. c. As noted earlier, the minor and major storm release rates should be based on Table SO -1. Table SO -1 has been used for the major and minor storm release rates. 6. On Worksheet P, Figure EDB -3 should be used to size the WQ orifices. As discussed at the drainage report meeting, with COWR staff. table OS - Page 11 of 20 I (from UDFCD Manual) was used to size the orifices and either equation EDB -3 or the table OS -1 has been used to resize the orifices when the new release rates are used. 7. On Worksheet Q, the minimum T, of 5 minutes should be used. The time of concentration has been revised to a minimum of 5 minutes. 8. On Worksheet R, the area used to calculate the runoff of W. 30th Avenue north of Sub -Basin 2 appears to be too small. By inspection of the surrounding area using the City's GIS, the basin area of this storm system is around 1.388 acres. Please re-evaluate using an area closer to what the actual basin is. The area has been revised to the 1.388 acres. The associated calculations has been revised to verify the existing storm sewer capacity. Final Drainage Plan (Appendix A): 1. Need to include a Historical Drainage Plan depicting the sub -basin information for the existing conditions. An existing site plan with the defined sub -basins has been added to the drainage drawings. 2. The contributing areas shown in the Summary Runoff Table do not match the information on Worksheet N in the Report Appendix. The values from the Proposed Drainage System has been updated on the Site Plan. 3. Design points should be included for sub -basins 1, 2, and 10 that are not conveyed to the EDB so that the flows can be compared to existing conditions. Design points for the sub -basins have been added. 4. Please rename the Proposed Stormwater Site Plan to "Final Drainage Plan". Drawing title has been revised. 5. The report states that the WQ holes are 7/8" diameter while the detail shows 13/16" The diameter has been revised in the detail and the report to reflect the revised diameters. MISCELLANEOUS COMMENTS 1. It appears that Conduit #23 may not be available to the City until the 2"d Quarter of 2015. If the City accepts the conduit then we would be Page 12 of 20 very interested in getting it much earlier than that date. This item will be covered in the IGA between DW and COWR. We propose to remove this item from the SUP. 2. The drain line for the tanks could possibly be connected to Conduit #23 if the City accepts the conduit as a drainage pipe. This would eliminate the need for the drain line construction on Gray Street. The tank drain line to be constructed on Gray Street requires a lower elevation than Conduit #23. Therefore. hydraulically the drain cannot be connected to Conduit #23. CONSTRUCTION TRAFFIC -Traffic Mitigation: 1. 30th Avenue is City ROW and cannot be used as a staging site or employee parking. All construction traffic must enter and exit the site on 29th Avenue only. The revised exhibit showing the proposed use for West 30"' Avenue is included under tab M of the SUP. All construction traffic will enter and exit the site on West 29t' Avenue only. With the information provided, street closures and detours will not be allowed. The contractor must maintain two-way traffic on 29th Avenue at all times. Flagging can be used to accommodate single lane closures on the other streets. All excavations must be filled and capped with asphalt each night or steel plates can be used to cover the excavations overnight. Street closures will be required to complete the project. Throughout the project duration there will be different street closures that will be coordinated with COWR. As the specific closure dates are approached the contractor will submit the required traffic control plans and specifics related to each closure for COWR approval. The excavation protection for overnight will be outlined in the additional information provided. 3. Construction material will not be allowed to be stockpiled in City ROW. Stockpiles will be maintained either on site at the tank construction site or at the Moffat YMCA park in Lakewood. Environmental Mitigation: 1. The City will review a Stormwater Management Plan when it becomes available. The Stormwater Management Plan. Maintenance Agreement and 0 and M Plan will be submitted to the COWR prior to final inspection of the project. Miscellaneous Mitigation: Page 13 of 20 in order to avoid an unsignalled left turn at 29"' and Sheridan, it would be preferable to return via a left turn at Wadsworth. then right turns at 32"", Sheridan & 29"'. Ashland Tanks Haul Route #2 (Demo and Fill To and From 1-70): 1. Option C, all traffic directed east on 29`" Avenue to Sheridan Boulevard, is the only option acceptable to the City. Haul Routes have been revised to have all traffic routed east of the site on West 29"' Avenue. Ashland Tanks Haul Route #3 (Ready Mix To and From 1-70): 1. None of the options shown are acceptable. All traffic must be directed east on 29th Avenue to Sheridan Boulevard. Haul Routes have been revised to have 2/3 of the traffic routed east of the site on West 29`" Avenue. Access to W 30"' Ave will still be required during the concrete pour days; therefore, the haul route 3C will need to be used for approximately 1/3 of the trucks on the pour days. PLANNING & ZONING Site Plan Review Sheets: Site Plan: 1. Modified Type 3A ADA ramps are required at the W. 29th Ave. & Fenton Street and W. 30th Ave. & Fenton Street intersections. Please show these ADA ramps on the Site Plan to verify they will fit the current proposed design. If the ramps do not fit the current design, a small corner of ROW may need to be deeded to the City to allow for future maintenance of the ramps. Please refer to the redlined Site Plan and attached Modified Type 3A ADA Ramp detail. (I will send you an AutoCAD DWG file of the ramps so you can insert them into your drawings). The ADA ramps have been added to the site plan drawings. 2. Need to add a City -standard mid -block ADA ramp at the northwest corner of the project (south side of W. 30th Avenue at Harlan Street). The ADA ramp has been added to the site plan drawings. 3. It appears the contours along the southerly side of the proposed tanks are altered to account for some landscaping. Since there is a separate sheet showing the proposed landscaping, please modify this so the contours are correctly shown on the Site Plan. The lines showing the flattened planting areas have been removed and only shown on Page 15 of 20 the landscaping drawings. 4. There is an area along Fenton Street where the sidewalk makes a slight jog to the west. Please describe why this jog is necessary, or modify the drawing and straighten the sidewalk. The sidewalk meander is due to an overhead electric (OHE) power pole. Per COWR comments all meanders in the sidewalk have been removed. 1. Subdivision Improvement Agreement Prior to the issuance of any Building or Right -of -Way Construction Permits or commencement of any construction activities, a Subdivision Improvement Agreement (SIA) will need be executed by the project owner/developer. The project owner/developer will need to contact Meredith Reckert, Senior Planner at 303-235-2848 to obtain a copy of the SIA. Please note that the SIA references the (approved) engineer's itemized cost estimate for the public improvements (see item 3 below). The SIA must be recorded at the Jefferson County Clerk & Recorder's Office prior to issuance of any Building or Right -of -Way Construction Permits. Per discussions with COWR, this item is not required. 2. Public Improvements Cost Estimate & Guarantee Prior to the issuance of any Building or Right -of -Way Construction Permits, or commencement of any construction activities, an itemized engineer's cost estimate will need to be submitted for review and approval. Upon acceptance of this estimate, an Irrevocable Letter of Credit (ILOC) reflecting the total costs of the approved cost estimate plus 25% (125% of the total estimate) shall be submitted by the owner / developer for review and approval at the time of SIA submittal. The ILOC shall remain in force for the entire duration of the project, and the City reserves the right to request the ILOC be renewed if deemed necessary. A photocopy of both the itemized cost estimate and ILOC will be attached to the SIA and recorded at the county. Per discussions with COWR, the Irrevocable Letter of Credit will not be required. The cost estimate will be submitted prior to the permits being issued. 3. Right -of -Way Construction Permits)/Licensing a. ROW Permits. Prior to any construction within the public right-of-way (ROW), the necessary Right -of -Way Construction Permit(s) and respective licensing will need to be submitted for processing by the City. Right -of -Way Construction Permits are issued by the City only after approval of all required technical documents, including but not limited to, the Final Drainage Report & Plan, Final Plat, Final Development Plan, Traffic Impact Study, Storm Sewer Plans, Street Construction Plans, Grading & Erosion Control Plan, Traffic Control Plan, and easement or ROW dedications. Page 16 of 20 b. Licensing. All work within the public Right -of -Way shall only be performed by a municipally -licensed contractor. ROW permits will be secured and appropriate licensing will be submitted in accordance with the COWR requirements. The general contractor will be in contact with COWR to get the ROW permits after all technical documents have been received and approved by COWR. 4. 2 -Year Warranty Period for Public Improvements Upon completion of all public improvements and Final Acceptance has been granted by the City Inspector, the original Irrevocable Letter of Credit shall be surrendered. At that time a 2 -year warranty period for the completed and approved public improvements shall commence. If at any time during said 2 -year Warranty Period the City Inspector deems that the constructed public improvements are in such condition as to require repairs or replacement, the Developer shall complete such work upon request. Upon commencement of the 2 -year Warranty Period, a 2nd Letter of Credit in the amount of 25% of the original itemized engineer's cost estimate shall be submitted to the City of Wheat Ridge and be dated as to expire on the 2 -year anniversary of the Warranty Period commencement date. The City shall retain said Letter of Credit for the entire 2 -year Warranty Period. Upon completion of the 2 -year Warranty Period, the 2nd Letter of Credit shall be surrendered by the City of Wheat Ridge. Per discussions between DW and CO WR the 2"`' Letter of Credit will not be required. The warranty period will be provided by the contractor who performs the work as required by the ROW permit. 5. Public Improvement Restoration/Debris Tracking It will be the responsibility of the contractor for the project to repair any damage to the existing public improvements along W. 30th Avenue, Fenton Street, W. 29th Avenue, or any other surrounding Wheat Ridge roadway damaged as a direct result of related construction traffic. Also, the contractor will be responsible for maintaining all affected roadways on a regular basis such that they remain free of construction debris and tracking from construction traffic accessing the site. This item will be covered in the IGA between DW and COWR. The specifics of road maintenance and repair requirements will be covered in the IGA. 6. Drainage Certification w/ As -Built Plans required prior to C.O. Upon completion of the drainage improvements, the Engineer -of -Record Mr. Adam T. Monchak, P.E., shall provide to the City of Wheat Ridge a written, signed and sealed Drainage Certification Letter stating that the overall site grading was completed per the approved Grading and Drainage Plans, all drainage facilities were constructed per the approved construction plans and shall function as defined in the approved Final Drainage Report/Plan, and that the site has been accurately surveyed to Page 17 of 20 confirm that the grading and construction of all drainage facilities was completed in accordance with these documents. The Drainage Certification Letter shall be submitted to the City for review and approval, and shall be accompanied with As -Built Plans on the Current City Datum for all constructed drainage facilities prior to issuance of the Certificate of Completion. Three (3) copies of the "As -Built" Plans are to be submitted as follows: a. One (1) hardcopy is to be signed & sealed on 24" X 36" bond paper, and b. Two (2) electronic files are to be delivered on DVD/CD-ROM as follows: One (1) file in AutoCAD 2009 DWG format and one (1) file PDF format. Denver Water will provide the certified surveying and TST Infrastructure, LLC. (Mr. Adam T. Monchak, P.E.) will provide a Certification Letter upon completion of the drainage improvements. The submittal will be per the requirement listed. 7. Stormwater Maintenance Agreement and O & M Plan Required All post -construction Best Management Practices (BMP's) for water quality must be maintained and inspected by the property owner(s) per Section 20-34 of the City of Wheat Ridge Municipal Code of Laws. For above -ground detention facilities with outlet structures, underground detention facilities, porous landscape detention areas, porous pavement, and centrifuge type devices such as a Rinker Stormcepter®, a Stormwater Maintenance Agreement accompanied by an Operations and Maintenance (O & M) Plan will be required prior to issuance of the Certificate of Occupancy. The O & M Plan shall be kept current and will be inspected on a regular basis by City staff to ensure compliance with the State and local requirements. The O & M Schedule/Log is typically assembled by the Engineer -of -Record, must be kept current by the property owner, and will be inspected on a regular basis by City staff to ensure compliance with City of Wheat Ridge Municipal Code requirements. Contact Bill LaRow, Stormwater Program Manager at 303.235.2871 for additional information. The Stormwater Management Plan, Maintenance Agreement and O and M Plan will be submitted to the COWR prior to final inspection of the project. Information Information pertaining to the Public Works development requirements, land surveying, platting, and ROW information, as well as the City's Standard Street Construction, and Stormwater/ Erosion Control Details are available on the City of Wheat Ridge website at: www.ci.wheatridge.co.us Page 18 of 20 Comments from City of Wheat Ridge Fire Protection District Comments made by Kelly Brooks; April 26 2012 The 2006 International Fire Code and 2006 IFC amendments adopted by the City of Wheat Ridge shall be met for new construction unless otherwise approved by the Division of Fire Prevention. In addition, the requirements of Chapter 14 of the 2006 IFC (Fire Safety During Construction and Demolition) and NFPA 241 (Standard for Safeguarding Construction, Alteration and Demolition Operations) shall apply. The IFC will be met for the construction project. 2. The applicant should be made aware that the proposed project may require one or more of the following Fire Department permits: Fire District Demolition permit Fire District building permit Per discussions with Kelly Brooks at WRFPD both of the permits will be required and the contractor will obtain the permits through WRFPD. 3. During the extended construction process, the Fire District requests that it be notified 24 hrs in advance of any proposed road closures in the vicinity of the construction site that would prevent Fire Department access to any building, property, or right-of-way within the Fire District. In addition, the Fire District requests that it be notified 24 hrs in advance of any proposed water supply interruptions in the vicinity of the construction site. Notification will be provide to the COWR Fire Protection District for outages and water supply interruptions. 4. One additional fire hydrant will be along 29 cnAvenue in order to meet water supply distance requirements. Any required hydrant(s) shall be in place prior to new construction on the project site. One additional Hydrant will be added at the NE corner of Ingalls Street and West 29"' Avenue. 5. Access from the public R.O.W. to the fire hydrants located along the north property line (2 locations inside the property fence) shall be maintained or an alternate water supply accessible to the fire department shall be established. Per discussions with Kelly Brooks at the WRFPD the existing hydrant at the NE corner of Fenton Street and West 30"' Avenue will provide adequate fire protection.

W1.62&6199 ..wder.». ,L, orT TO: Whom it May Concern FROM: Craig Austin, Manager of Safety & Security DATE: June 5, 2012 SUBJECT: Perimeter Security - Ashland Reservoir Dear Sir/Madame, As you are aware, Denver Water (DW) is in the final design stages of the Ashland Reservoir facility, which will be located at 2901 Fenton St. When complete, this facility will consist of two (2) 10 Million Gallon Potable Drinking Water Reservoirs and associated Water Quality Monitoring Station facilities. The facility will support the service of drinking water to the approximately 1.2 million drinking water customers in and around the City & County of Denver, and just as importantly, the facility will support Critical services such as firefighting, health care (hospitals and clinics), and other dependent and interdependent vital functions that would suffer negative impacts from a denial of water service from this facility. The Department of Homeland Security (DHS) has identified the drinking water sector as one of 17 National Critical Infrastructure/Key Resources (Cl/KRs). The decision to include the water sector is based on the fact that the drinking water sector is vulnerable to a variety of potential attacks, including contamination with deadly agents, and physical and cyber attacks. If these attacks were to occur, the result could be large numbers of illnesses or casualties or denial of service that would also affect public health and economic vitality. Therefore, as we went about designing the facility we wanted to be sure to include security concepts and features that provide the level of security commensurate with the importance of a facility of this nature. In doing so we followed the guidance provided in the DHS National Infrastructure Protection Plan, the DHS Water Sector Specific Plan, as well as industry -specific "Guidelines for the Physical Security at Water Utilities". With regards to security vulnerabilities, we also had the benefit of learning from risk assessments at many similar facilities to include those in DW's inventory. With all that being said, we wanted to address your specific request to have "brick pillars" integrated into the perimeter fencing for aesthetics purposes. While we agree that brick pillars do present an aesthetically pleasing appearance, they do not fit in with any of the primary purposes of a perimeter fence, especially as it applies to this type of facility. To the contrary, they would provide an attractive and easy method for an adversary to compromise the perimeter by scaling the pillar(s) using the hand and foot holds naturally provided in the structures. Additionally, they also provide areas (potentially 24) that cannot be observed from the inner perimeter. As such an adversary or some number of adversaries could use the area behind the pillars to provide cover of their activities or to hide or stage materials for later use. CONSERVE In 2004 DW installed new perimeter fence at two locations and included these structures in a portion of those perimeters. Subsequently, we've had several independent security risk assessments conducted at these facilities, and this aspect of the perimeter fence has been quickly and easily identified as a vulnerability that an adversary would likely take advantage of. Further, although DW has subsequently completed several new and/or existing fencing improvement projects we have not used this design feature, nor do we intend to, based primarily on the clear vulnerability it presents. In closing, we believe you will be equally pleased by the fence product included in the design. It is marketed as presenting an aesthetically pleasing appearance that fits well even in a residential setting as well as meeting the very important need of providing an effective security feature. As a neighbor we appreciate your input and look forward to working with you as we complete the design and begin construction. Please call or email if you have you have any questions. Respectfully, 1 Craig Austin Manager of Safety & Security Denver Water / City of Wheat yidge COMMUNITY DEVELOPMENT City of Wheat Ridge Municipal Building 7500 W. 29`h Ave. Wheat Ridge, CO 80033-8001 P: 303.235.2846 F: 303.235.2857 May 4, 2012 Martin Garcia, P.E. Denver Water 1600 West 12`x' Avenue Denver, CO 80204-3412 Dear Mr. Garcia: This letter is in regard to your request for approval of a Special Use Permit with variances to allow reconstruction of the Denver Water Ashland Reservoir facility in an R-1 zone at 2901 Fenton Street. I have reviewed the first submittal and have the following comments: APPLICATION BINDER I . Section B: In the letter of request, please be more specific regarding the variation from permitted construction days and hours. This should relate back to the anticipated construction schedule and the four construction "milestones" when work days and hours will exceed the City's standard. 2. Section C: In the responses to the SUP evaluation criteria, #3., expand discussion about the construction impacts and how these will be mitigated. 3. Section C: In the responses to the SUP evaluation criteria, #4, discuss construction parking. 4. Section C: In the responses to the SUP evaluation criteria, #6, discuss construction traffic and proposed mitigation. 5. Section D: In the responses to the variance evaluation criteria, A, be more specific regarding the need for variance from permitted construction days and hours. 6. Section D: In the responses to the variance evaluation criteria, D, address the grades relative to the surrounding properties and challenges as a result (topographic conditions). 7. Section D: In the responses to the variance evaluation criteria, E, please address hardship. 8. Section E, please modify the construction activities to highlight the four critical construction points that require the longer days and hours. 9. Section M: In the Traffic Impact Table, are the bolded dates, the four critical construction points? Please clarify with notes. PLAN SET SHEET 1 (DECLARATION SHEET) 1. A site plan for SUP approval is not typically recorded. If you do want to record it, the following modifications will be required: Add a legal description, modify the Jefferson County Clerk and Recorder's certificate to their standard signature/recording block, and designate who will be signing as the property owner with proper notary attestation block. 2. Modify the City Council signature block to read as follows: Approved this day of by the City of Wheat Ridge City Council". 3. Add a case history box with the following case number: SUP -12-03. 4. The final photometric plans need to be incorporated into the review plan set. The sheet numbers need to be numbered accordingly with the first sheet being l of 12 (or whatever this total sheet numbers will be). The renderings will not be recorded. www.ci.wheatridge.co.0 s SHEET 2 (EXISTING S11 r. PLAN) 1. Renumber the sheet number accordingly. SHEET 3 (PROPOSED SITE PLAN) I . Renumber the sheet number accordingly. 2. In the drawing, on the southern portion of Fenton Street, there is a meander in the sidewalk. What is this obstruction? Please identify. 3. In the development standards chart, indicate number of parking spaces for service vehicles on the southern pull -in from W. 29`h' Avenue. SHEET 4 (LANDSCAPING PLAN) 1. Renumber the sheet number accordingly. 2. The number of street trees required at a 1/35' ratio appears adequate in number and for species with one exception. On the drawing at the northwest corner of the property, six American Compact Cranberry bushes (ACC) are shown. These are shrubs and need to be replaced with acceptable street trees. 3. The number of additional trees and shrubs required is inadequate. Per Section 26-502 of the zoning and development code, one additional tree and ten shrubs are required for every 1000 square feet of required landscaped area. My calculations indicate that only 42 additional trees are provided where 72 are required. The required shrub count is for 720 shrubs where 541 shrubs are provided. Please modify the landscape plan (all sheets) to meet these minimums. 4. Add the following note: All landscaped areas shall be served by a fully automatic, zoned irrigation system. 5. Add the followingnote: Proposed native K�' e � @d p grass seed mix variety and application shall be app�e� by the City of Wheat Ridge. PHOTOMETRIC PLAN SET 1. The photometric plan set will eventually need to be incorporated into the plan review set for public hearing and recording. The renderings will not be recorded. 2. The interim construction site lighting along West 29`h and 30th Avenues is not in conformance with the City's standards for exterior lighting. Although this is considered interim construction lighting, the three year timeframe for project completion will have tremendous impacts on the adjacent low density neighborhood. Therefore, staff will not support the interim lighting plan as submitted. 3. The final site lighting along West 20 and 30`h Avenues is not in conformance with the City's standards for exterior lighting. OTHER ITEMS: 1. Staff highly recommends that the perimeter fencing be upgraded to include brick pillars evenly spaced at 100' intervals adjacent to street rights-of-way. 2. As construction parking will not be allowed in the West 301h Avenue right-of-way, Staff would suggest that area churches be contacted to see if they would allow construction parking. There are two churches in the immediate vicinity at 6475 W. 291h Avenue and 6310 W. 29th Avenue. Another suggestion would be to build a temporary lot on the vacant property located just to the southwest of the reservoir. This property is located in the City of Edgewater. Your request was sent out for referral and the following are comments received: City of Edgewater: See attached emailfrom om Brea Pafford dated May 3, 2012. Wheat Ridge Sanitation District.

Dear Ms. Monchak, I have completed the first review of the above referenced documents received on April 16, 2012, and I have the following comments: LAND SURVEYING Right -of -Way Deed: 1. The City of Wheat Ridge requires all plats and dedications to include tie(s) to section or quarter - corners on only (aliquot corners are not acceptable for use in section ties). To complete the section -tie in the Legal Description, please provide the distance from the Point of Commencement (Center Quarter -Corner, Section 25) to the southwest corner of the northwest quarter of the southeast quarter (center -south sixteenth corner) of Section 25. 2. Include the above-mentioned distance on the graphical portion of the Exhibit A. 3. Modified Type 3A ADA ramps are required at W. 29`h Ave. & Fenton St. and W. 30`h Ave. & Fenton St. Depending on how the required ramps fit a small corner of ROW may need to be deeded to the City for future maintenance of the ramps (please refer to comment 1 for the Site Plan). CIVIL ENGINEERING DRAINAGE Final Drainage Report (Discussion): 1. Under II. B of the Historic Drainage System section of the Report, please discuss the historical sub - basins, their respective areas, discharge points, and Q5 & Qtoo for each sub -basin. The discussion seems to indicate at least 3 sub -basins. This information can then be utilized in the Conclusion section to compare with the proposed design in support of statements made that the proposed design does in fact improve the site drainage conditions and lowers the impacts to downstream storm systems and properties. 2. Under Section III. B. Runoff: a. Provide information regarding the sub -basin design point locations and release rates for the minor and major events at each DP. b. Discuss the flow proposed for release from sub -basin 2 into W. 30`h Avenue, and demonstrate the capacity of the existing storm sewer and inlet is sufficient to handle the additional runoff. www.d.wheatridge.co.us Public Works Engineering April 27, 2012 Page 2 Please note that from the City's GIS the area that appears to drain into the existing W. 30,h Avenue storm sewer is at least 1.388 acres. c. It appears that sub -basin 10 flows directly onto W 29th Avenue. The impact of this flow needs to be discussed. It also appears that the most of the paved area in this sub -basin is above the water elevation in the EDB, so an inlet and pipe could be added that would convey the runoff to the EDB. d. Rather than having statements that "anticipate" various results, a table comparing the existing and proposed flows at the various discharge locations should be included. 3. Under Section III C. Detention : a. The discharge rates for the WQCV should be based on the 40 -hr release rate. We allow the 24 - hr rate for very small sites. The minor and major storm release rates should be based on Table SO -1, not on the WQ drain times. b. It is stated that the EDB spillway will be located on the west side and sized for the "tank overflow scenario". It appears in the event of a catastrophic "tank overflow" event the water flow down Gray Street, crossing W. 26th Avenue and into the City of Edgewater. In light of this "scenario", please discuss the downstream impacts under this scenario and provide calculations for Gray Street and a couple of cross-sections depicting the anticipated flow depth at those locations under the "tank overflow" condition. All flows should be stated in "cfs" for ease of comparison. c. Looking at the contours downstream of the proposed overflow spillway it appears that there may be potential liability for Denver Water under the "tank overflow" scenario, and as such the City of Wheat Ridge strongly recommends Denver Water provide this design to the City of Edgewater for their approval. 4. Under Section III F. Open Channel Flow, please describe where the channel running along the easterly edge of sub -basin 9 flows to (i.e., into the detention facility, to Fenton St., etc.). 5. Under Conclusions: a. Section A. Impact oflmprovements. While it is acknowledged that the proposed design reduces the overall site imperviousness, please provide a comparison between the historical conditions and Q's with the proposed design and values. b. Discuss the benefits of the present design over the existing conditions and the impacts to downstream properties and storm systems. c. Section B. Compliance with Applicable Criteria. In the third sentence of the third paragraph it is stated that "The estimated depth at the 6 inch curb ... will be 5.16 inches." Later on flow spread and velocity is also discussed. Please define what roadway(s) this paragraph is referring to (this project is bounded by three roadways, with existing 6" vertical curbing along two of them). d. A comparison between the historic runoff quantities versus the proposed developed runoff Q's should be included in this section. Final Drainage Report (Appendices C - E): 1. Worksheet A needs to be divided into the various sub -basins for the existing conditions. 2. On Worksheet L, the following corrections should be made: a. The initial/overland time is based on sheet flow conditions. The maximum length is 300 feet in urban watersheds. As soon as the flow is concentrated in swale, gutters, etc. then the travel time should be used. b. The minimum Tc for urban watersheds is 5 minutes. The equation used in the Tc check is the maximum Tc that should be used, not the minimum. 3. On Worksheets M and N, the routing of the flows through the storm sewer system has not been done properly. www.ci.wheatridge.com s Ashland Reservoir -2901 Fenton St—ROW Deed-FDR-SUP_reviewI Itr MAW.docx Public Works Engineering April 27, 2012 Page 3 4. On Worksheet N, the Qloo and contributing areas do not match the Summary Runoff Table found under the Proposed Drainage System on the Proposed Stormwater Site Plan. 5. On Worksheet O, the following corrections should be made: a. Only the tributary area for the EDB should be used to size the WQCV and the detention volumes. b. As noted earlier, only the 40 -hr release rate calculations should be used. c. As noted earlier, the minor and major storm release rates should be based on Table SO -1. 6. On Worksheet P, Figure EDB -3 should be used to size the WQ orifices. 7. On Worksheet Q, the minimum Tc of 5 minutes should be used. 8. On Worksheet R, the area used to calculate the runoff of W. 301h Avenue north of Sub -Basin 2 appears to be too small. By inspection of the surrounding area using the City's GIS, the basin area of this storm system is around 1.388 acres. Please re-evaluate using an area closer to what the actual basin is. Final Drainage Plan (Appendix A): I . Need to include a Historical Drainage Plan depicting the sub -basin information for the existing conditions. 2. The contributing areas shown in the Summary Runoff Table do not match the information on Worksheet N in the Report Appendix. 3. Design points should be included for sub -basins 1, 2, and 10 that are not conveyed to the EDB so that the flows can be compared to existing conditions. 4. Please rename the Proposed Stormwater Site Plan to "Final Drainage Plan". 5. The report states that the WQ holes are 7/8" diameter while the detail shows 13/16" MISCELLANEOUS COMMENTS 1. It appears that Conduit #23 may not be available to the City until the 2" d Quarter of 2015. If the City accepts the conduit then we would be very interested in getting it much earlier than that date. 2. The drain line for the tanks could possibly be connected to Conduit #23 if the City accepts the conduit as a drainage pipe. This would eliminate the need for the drain line construction on Gray Street.

Dear Ms. Monchak, I have completed the first review of the above referenced documents received on April 16, 2012, and I have the following comments: LAND SURVEYING Right -of -Way Deed: 1. The City of Wheat Ridge requires all plats and dedications to include tie(s) to section or quarter - corners on only (aliquot corners are not acceptable for use in section ties). To complete the section -tie in the Legal Description, please provide the distance from the Point of Commencement (Center Quarter -Corner, Section 25) to the southwest corner of the northwest quarter of the southeast quarter (center -south sixteenth corner) of Section 25. 2. Include the above-mentioned distance on the graphical portion of the Exhibit A. 3. Modified Type 3A ADA ramps are required at W. 291h Ave. & Fenton St. and W. 30`h Ave. & Fenton St. Depending on how the required ramps fit a small corner of ROW may need to be deeded to the City for future maintenance of the ramps (please refer to comment 1 for the Site Plan). CIVIL ENGINEERING DRAINAGE Final Drainage Report (Discussion): 1. Under II. B of the Historic Drainage System section of the Report, please discuss the historical sub - basins, their respective areas, discharge points, and Q5 & Q100 for each sub -basin. The discussion seems to indicate at least 3 sub -basins. This information can then be utilized in the Conclusion section to compare with the proposed design in support of statements made that the proposed design does in fact improve the site drainage conditions and lowers the impacts to downstream storm systems and properties. 2. Under Section III. B. Runoff: a. Provide information regarding the sub -basin design point locations and release rates for the minor and major events at each DP. b. Discuss the flow proposed for release from sub -basin 2 into W. 301h Avenue, and demonstrate the capacity of the existing storm sewer and inlet is sufficient to handle the additional runoff. www.ci.wheatridge.co.us Public Works Engineering April 27, 2012 Page 2 Please note that from the City's GIS the area that appears to drain into the existing W. 301h Avenue storm sewer is at least 1.388 acres. c. It appears that sub -basin 10 flows directly onto W 29t1i Avenue. The impact of this flow needs to be discussed. It also appears that the most of the paved area in this sub -basin is above the water elevation in the EDB, so an inlet and pipe could be added that would convey the runoff to the EDB. d. Rather than having statements that "anticipate" various results, a table comparing the existing and proposed flows at the various discharge locations should be included. 3. Under Section III C. Detention : a. The discharge rates for the WQCV should be based on the 40 -hr release rate. We allow the 24 - hr rate for very small sites. The minor and major storm release rates should be based on Table SO -1, not on the WQ drain times. b. It is stated that the EDB spillway will be located on the west side and sized for the "tank overflow scenario". It appears in the event of a catastrophic "tank overflow" event the water flow down Gray Street, crossing W. 26th Avenue and into the City of Edgewater. In light of this "scenario", please discuss the downstream impacts under this scenario and provide calculations for Gray Street and a couple of cross-sections depicting the anticipated flow depth at those locations under the "tank overflow" condition. All flows should be stated in "cfs" for ease of comparison. c. Looking at the contours downstream of the proposed overflow spillway it appears that there may be potential liability for Denver Water under the "tank overflow" scenario, and as such the City of Wheat Ridge strongly recommends Denver Water provide this design to the City of Edgewater for their approval. 4. Under Section III F. Open Channel Flow, please describe where the channel running along the easterly edge of sub -basin 9 flows to (i.e., into the detention facility, to Fenton St., etc.). 5. Under Conclusions: a. Section A. Impact of Improvements. While it is acknowledged .that the proposed design reduces the overall site imperviousness, please provide a comparison between the historical conditions and Q's with the proposed design and values. b. Discuss the benefits of the present design over the existing conditions and the impacts to downstream properties and storm systems. c. Section B. Compliance with Applicable Criteria. In the third sentence of the third paragraph it is stated that "The estimated depth at the 6 inch curb ... will be 5.16 inches." Later on flow spread and velocity is also discussed. Please define what roadway(s) this paragraph is referring to (this project is bounded by three roadways, with existing 6" vertical curbing along two of them). d. A comparison between the historic runoff quantities versus the proposed developed runoff Q's should be included in this section. Final Drainage Report (Appendices C - E): 1. Worksheet A needs to be divided into the various sub -basins for the existing conditions. 2. On Worksheet L, the following corrections should be made: a. The initial/overland time is based on sheet flow conditions. The maximum length is 300 feet in urban watersheds. As soon as the flow is concentrated in swale, gutters, etc. then the travel time should be used. b. The minimum Tc for urban watersheds is 5 minutes. The equation used in the Tc check is the maximum Tc that should be used, not the minimum. 3. On Worksheets M and N, the routing of the flows through the storm sewer system has not been done properly. www.ci.whentridge.co.us Ashland Reservoir -2901 Fenton St—ROW Deed-FDR-SUP_reviewI Itr MAW.docx Public Works Engineering April 27, 2012 Page 3 4. On Worksheet N, the Q100 and contributing areas do not match the Summary Runoff Table found under the Proposed Drainage System on the Proposed Stormwater Site Plan. 5. On Worksheet O, the following corrections should be made: a. Only the tributary area for the EDB should be used to size the WQCV and the detention volumes. b. As noted earlier, only the 40 -hr release rate calculations should be used. c. As noted earlier, the minor and major storm release rates should be based on Table SO -1. 6. On Worksheet P, Figure EDB -3 should be used to size the WQ orifices. 7. On Worksheet Q, the minimum Tc of 5 minutes should be used. 8. On Worksheet R, the area used to calculate the runoff of W. 301h Avenue north of Sub -Basin 2 appears to be too small. By inspection of the surrounding area using the City's GIS, the basin area of this storm system is around 1.388 acres. Please re-evaluate using an area closer to what the actual basin is. Final Drainage Plan (Appendix A): 1. Need to include a Historical Drainage Plan depicting the sub -basin information for the existing conditions. 2.

A neighborhood meeting will be held on: Tuesday, February 21, 2012 from 6:30 pm to 8:00 pm. The Sons of Italy Lodge, 5925 West 32nd Avenue (32nd Avenue between Harlan and Gray) The purpose of the meeting is to allow for neighborhood input, review proposed plans and speak with representatives from the City of Wheat Ridge and Denver Water about the proposed project. The current zoning on the property is R-1. A special use permit is being required by the City of Wheat Ridge to allow the reconstruction of the reservoir. The City of Wheat Ridge requires that prior to any application for Special Use Permits the applicant (Denver Water) must notify all residents and property owners within 600 feet and invite then to a Neighborhood Input Meeting. The meeting will be an opportunity for Denver Water staff to present plans to improve the safety and reliability of its Ashland Reservoir site by building two new underground water storage tanks. Neighbors will have an opportunity to ask questions and express their concerns and issues about the project. A Staff Planner from the City of Wheat Ridge will attend the meeting to discuss City policies and regulations and the process involved however, the Staff Planner will remain impartial regarding the viability of the project. This is not a public hearing rather an informational meeting with neighbors which offers an opportunity to discuss the project. A synopsis of the meeting will be entered as testimony; however it is the public hearing in front of City Council where decisions on the Special Use Permit are rendered. If you want input in the decision-making process, it is imperative you attend the public hearing. Neighbors may have the following concerns which Denver Water would like to discuss at the meeting: Project schedule Construction impacts such as dust and noise Traffic and street impacts Project designs which can enhance the neighborhood Storm drainage Suggestions from neighbors on the proposed plans Denver Water has a website with information on the project www.denverwater.org/ashland. If the permit is approved, the site will appear different from the existing site. The new tanks will have a smaller footprint, which will create a larger landscaped area. The existing chain link fence will be removed and will be replaced by a black, 8 -foot -high ornamental steel fence. If you have any questions, please call the Planning Division at 303-235-2846. If you are unable to attend the meeting, you may mail comments or concerns to: City of Wheat Ridge Community Development Department 7500 West 29th Avenue Wheat Ridge, CO 80033 Meredith Reckert From: Sloan, Joseph A. <Joseph.Sloan@denverwater.org> Sent: Tuesday, February 07, 2012 11:22 AM To: Meredith Reckert Cc: Garcia, Martin Subject: Notice goes out today Attachments: Ashland SUP Notice final.docx Hello Meredith The notice went out today.

Joe Sloan i Community Relations Denver Water 1303-628-6320 http://www.denverwater.org January 4, 2012 Dear Neighbors of Ashland Reservoir: Denver Water plans to improve the safety and reliability of its Ashland Reservoir site by building two new underground water storage tanks. The design for the site is being developed and construction is scheduled to begin in fall 2012. Neighbors will notice more activity at the site as Denver Water staff members and contractors visit the site as part of the design process. Western Summit has been hired by Denver Water as the construction manager for the project. As part of a phased project, Western Summit will demolish one of the two existing tanks and build a new tank in its place. Once that tank is in service, the second tank will be demolished and another tank built in its place. The two tanks cannot be demolished at the same time because the water stored at the site is needed for customers and for fire protection. The entire project is scheduled to run through 2015. The contractor for the project will be required to follow work hours, as set forth by the City of Wheat Ridge. Denver Water staff has met with representatives from the City of Wheat Ridge to discuss the project. As the project proceeds, Denver Water and its contractors will continue to meet with city staff to discuss potential impacts, and mitigation plans, for the project. Large portions of the berms on the west and east sides of the site will be kept in place to reduce noise from demolition and construction. Part of the south berm will be removed initially for access to the site off of 29th Avenue. Additional sections of the south berm may be removed for use as a storage area for the project. Additional information, a site map and a photo simulation of the site are available at www.denverwater.org/ashland. Once completed, the site will appear different from the existing site. The new tanks will be circular and smaller than they are now. The new tanks will have a smaller footprint, which will create a larger landscaped area on the south side of the property. The existing chain link fence will be removed and will be replaced by a black, 8 -foot - high ornamental steel fence. The City of Wheat Ridge will require Denver Water to go through a Special Use Permit (SUP) process prior to finalization of the design of the site. There will be a pre -application neighbor- hood meeting required as part of the SUP process. If residents have questions about the SUP process, they can contact Meredith Reckert, at 303-235-2848 or mreckert@ci.wheatridge.co.us. Updates on the project will be posted at www.denverwatenorg/ashland. Please contact me if you have any questions or concerns.

Plan: Neighborhood Existing Site Conditions: The property is located on six (6) acres north of W. 29`h Avenue, east of Fenton Street, and south of W. 30`h Avenue. The parcel does not have an assigned street address. The property is zoned Residential -One (R-1) and is almost entirely surrounded by residential neighborhoods. To the north and west are properties zoned Residential -Three (R-3). To the south is a single-family neighborhood zoned Residential -One C (R -1C). Across Fenton are properties zoned R-3, R -3A, and Commercial -One (C-1); these lots include the Wheat Ridge Manor Nursing Home, a gas station, and an auto repair shop. To the southwest across W. 291h Avenue are properties outside the boundary of the City of Wheat Ridge in the City of Edgewater. The site contains Denver Water's Ashland Facility which includes two (2) underground reservoirs with a combined storage capacity of 41 million gallons of water (19 million and 22 million, respectively). The site has been home to a treated water facility since the late 1800's. A series of upgrades have occurred over the last 100 years, including the installation of a precast concrete roofing system in the 1970s. This roofing system exists today and covers much of the site. The elevation of W. 301h Avenue is nearly 20 feet higher than W. 291h Avenue. Steep berms run along the south and west property lines, and a retaining wall has been constructed along Fenton to address the topography of the site. A small well house is located on the south side of the property. A chain link fence surrounds the entire property, and the primary vehicular access point is from W. 30`h Avenue. The Ashland Facility is one of only a few reservoirs in the north end of the region. Ashland is primarily fed by Denver Water's Moffat Treatment Plant at W. 201h Avenue and Quail Street. There is no pump station on the subject property; the water is transported by gravity flow east to Denver. Applicant/Owner Preliminary Proposal: The applicant, Denver Water, is proposing to demolish the existing reservoirs and construct two concrete water tanks that are 256 feet in diameter. Each tank will accommodate 10 million gallons of water; they will be 28-30 feet deep, but only 1-2 feet will be visible above grade. The existing facility is deteriorating and has reached the end of its useful life. In addition, the existing reservoirs provide excessive storage capacity, which combined with degradation has created water quality concerns. The replacement project is expected to begin construction in October 2012 and take approximately three (3) years to complete. In addition to replacing and downsizing the reservoirs, the redesign will reduce the amount of impervious surface. The basins will consume the northern two-thirds of the site and the southern portion will be landscaped to more gradually accommodate the change in elevation. A detention pond will be located at grade at the intersection of W. 291h Avenue and Fenton. A parking area and unmanned water quality facility are also planned to be located on the W. 29`h Avenue frontage. The existing chain link fence is proposed to be replaced with a more decorative 8 -foot high wrought -iron fence. Vehicular access to the water tanks will still come from W. 30`h Avenue, and a driving path will encircle the two basins. The project team is evaluating the feasibility of providing a hydropower facility on site somewhere along the north side of the property. Following the replacement of the basins, Denver Water also seeks to upgrade piping and drain lines within surrounding rights-of-way, including Gray Street, Fenton Street, and W. 29`h Avenue to Sheridan. Will a neighborhood meeting need to be held prior to application submittal? Yes, a neighborhood meeting will be required prior to submitting an application for a Special Use Permit. Planning comments: The following items were discussed based on the applicant's proposed development: Special Use Permit The site is zoned Residential -One (R-1), a zone district that provides for high quality, safe, quiet and stable low-density residential neighborhoods, and prohibits activities of any nature which are incompatible with the low-density residential character. Quasi -governmental uses are permitted in the R-1 zone district, but quasi -governmental uses with outside storage require a Special Use Permit. The Denver Water facility is considered a quasi -governmental use; but the water storage requires an SUP. A Special Use Permit is also required based on the scope of the excavation and fill operations. Per Municipal Code Section 26-623, any dumping, landfill, and/or extraction operation that exceeds 2 20,000 cubic yards is allowed only by Special Use Permit. A Major Grading/Fill Permit is issued upon and in conformance with the SUP; please see Public Works' comment section below. The two SUP requests can be processed simultaneously. The SUP process is described below. Construction Logistics The City of Wheat Ridge does not regulate decibel levels specifically for construction projects. Section 16-103 of the City Code addresses "Unreasonable noise; Disturbing the Peace." This ordinance generally prohibits noise that is loud enough to bother others between the hours of 11:00 p.m. and 7:00 a.m. The performance standards associated with the Major Grading/Fill Permit include restrictions on hours of operations. Activities are permitted from 7:00 a.m. to 5:00 p.m. and are prohibited on weekends and holidays. Restricted hours of operation for construction will likely be a condition of the Special Use Permit. Currently, staff is unlikely to support an on-site concrete processing facility because of the associated noise and dust. This could be reconsidered if on-site processing will result in usable fill material and a significantly reduced number of truck trips. Staff anticipates neighborhood resistance to on-site processing. City Council Study Session Staff recommends that the applicant present this project at the August 22nd City Council Study Session. Plans may be conceptual in nature, but should include a general introduction to the scope, rationale, timeline, and impacts associated with the project. The council members of the City of Wheat Ridge have historically had close relationships with constituents, and it will be important to keep council members informed from an early stage. Renderings Staff has considered the applicant's wide format images, and would prefer renderings that use images #829, #935, #1029, and #1040. If possible, image #1029 maybe more informative if taken from a point closer to the intersection of W. 291h Avenue and Fenton. Development Standards The following development standards apply to non-residential uses in residential zone districts. Based on preliminary review of the site plan, the applicant may not be able to fully comply with all standards. The zoning code standards and references are listed below. As the applicant develops the site plan, variances may be discussed with staff, all variance requests will be processed with the SUP as needed. Parking & Paving Section 26-501.E.5 of the zoning code requires areas subject to wheeled traffic for access, parking, or storage to be properly graded for drainage and surfaced with concrete, asphalt or brick pavers. The code does not include a variance from this requirement; the applicant may be able to request a waiver from City Council. If a waiver is considered, staff will likely recommend a minimum of 25 feet from the edge of street pavement into the site be hard surfaced. Section 26-501.E.6 requires a 6 -foot landscape buffer between parking areas and adjacent low - or medium -density residential uses. This will apply to the parking area on the south side of the site. Similarly, screening is required for parking or loading areas between a structure and the right-of-way. Fencing & Landscaping Staff requests that fencing is kept to a minimum and landscaping is located between the street and fence wherever possible. An 8 -foot high fence will require a variance from the 6 -foot height maximum for fences. This request will be incorporated into the SUP request and processed as a single application. A conceptual landscape plan will be required with the application for the Special Use Permit; a final landscape plan will accompany the building permit application. The landscape plan should consider the following, per Section 26-502.D.3: • Landscaping shall not be less than twenty percent of the gross lot area. • Private street trees are required for every 30 feet of street frontage, ornamentals are permitted • One (1) tree and ten (10) shrubs are required for every one thousand (1,000) square feet of required landscape area. • Nonresidential uses on residentially zoned property require a minimum ten -foot landscape buffer adjacent to public streets abutting front or side yards. • All nonresidential uses located adjacent to residentially zoned areas or agriculturally zoned areas shall provide a screened or landscaped buffer area consisting of either or both of the following: (1) A six-foot high solid fence or landscaped hedge with a mature height of six (6) feet; or (2) A strip of land at least fifteen (15) feet wide planted with a variety of vegetation and a minimum density of one (1) shrub or tree per every two (2) linear feet of buffer area adjacent to the residential or agricultural zoned property. Again, any waiver or variance from the landscaping requirement may be considered by City Council in conjunction with the SUP. Setbacks For the purpose of determining setbacks, the lot lines shall be interpreted as indicated in the table. Minimum setbacks for the R -I district are in Section 26-205 of the zoning code; any side or rear yard which abuts a public street has an increased setback requirement. Special Use Permitting Process: The requests for water tank storage and a Major Grade/Fill Permit will require a Special Use Permit. The first step in the SUP process began with the pre -application meeting on July 28, 2011. 4 Setback ELORerty Line Front 30 feet South lot line (W. 291Avenue Rear 30 feet North lot line (W. 30th Avenue) Side 30 feet East lot line (Fenton Street) Side 15 feet West lot lines Special Use Permitting Process: The requests for water tank storage and a Major Grade/Fill Permit will require a Special Use Permit. The first step in the SUP process began with the pre -application meeting on July 28, 2011. 4 The second step required by the Community Development Department will be to conduct a neighborhood meeting. For this meeting, the applicant must notify all property owners within a 600 -foot radius of the property. Notification may be via mail or hand delivery to all physical and owner addresses. The applicant will supply all addresses. A sample notification letter will be provided and may be used as a template. The letter will need to be approved by a planner before it is mailed. Notification should include the tenants and owners of all properties along haul routes. The neighborhood meeting should be coordinated with the assigned staff member. A fee of $100 is required for staff to be present at this meeting. The meetings can be held at City Hall in the Council Chambers or at any location the applicant desires. All costs associated with meeting, its location, and mailings will be paid by the applicant. The meeting will be led by the applicant and should inform those who are in attendance what is being proposed. After the neighborhood meeting is held, the applicant may submit their application for the Special Use Permit. Submittal requirements for this project will include: • Site plan and elevations • Traffic management plan with haul routes • Public outreach strategy • Construction management plan and schedule • Drainage report • Conceptual landscape plan Upon the submittal of the application for the Special Use Permit, the application will be reviewed by the case manager and sent to outside agencies for review (e.g. utility districts, fire district, Xcel, etc.). This referral period is 15 days long and allows time for agencies to comment on the application. Modifications to the application may be required as a result of these comments. Once the review of the application is complete, the property must be posted for a minimum of 10 consecutive days. In addition to the sign, the Community Development Department will send written notification of the request to property owners within 300 feet. If no legitimate complaints regarding the request are received within the 10 -day period, the application for a Special Use Permit may be reviewed administratively. If a complaint is received by the Community Development Department or if the Community Development Director feels the criteria have not been met, then the request for the Special Use Permit will be decided upon at a public hearing before the City Council. If a hearing before City Council is required for any reason, the neighborhood will be notified and the property shall be posted for a 15 -day period. At the public hearing staff will present evidence to recommend the approval, approval with conditions, or denial of the Special Use Permit. The public will be allowed to present evidence or give testimony in support or in opposition of the project. The City Council will approve, approve with conditions, or deny the project based on the testimonies given by staff, applicant and the public. Architectural and Site Design Manual (ASDM) The Architectural and Site Design Manual (ASDM) does not apply in this case. Building Division comments: The building division was not present at the meeting, but has the following comments: The use tax rate in Wheat Ridge is equal to 3% and is usually assessed when the building permit is issued. Use tax is typically pre -paid in lieu of paying local sales tax on construction materials at the 5 time of purchase. Every person who obtains a permit must pay use tax on materials used regardless of their tax exempt status, per Section 22-68 of the Municipal Code. Building permit fees are based on project valuation, and use tax is typically based on 3% of 60% of the project valuation. For questions related to use tax, please contact the Tax and Licensing Division (303-235-2825). For question related to project valuation, please contact the Building Division (303-235-2855). Public Works comments: Public Works was present at the meeting and has the following comments: Haul Routes Haul routes will need to be a continued point of discussion with the Public Works Department. West 291h Avenue is a collector street, and is scheduled to be repaved between the subject property and Wadsworth prior to the replacement project. For this reason, this section of roadway west of the site will not be permitted to be used as a haul route; haul routes will need to go east. Public Works will consider use of Fenton Street at the applicant's request. Use of the old Ford Site for staging or storage will not be supported by staff. The paved and unpaved parcels at the southwest intersection of Wadsworth and W. 38`h Avenue, are together considered one of the City's highest priorities for redevelopment. The City is actively working with property owners and potential developers who have expressed an interest in assembling and/or developing the area. Right-of-way Dedication The project will require a right-of-way dedication at the south end of the site along W. 291h Avenue. The resulting right-of-way width will need to be 61 feet wide to accommodate a standard street section with sidewalk and amenity zone. The dedication may be conveyed by deed. Staff prefers realignment option two, whereby improvements on 291h Avenue are symmetrical. Public Improvements As part of the basin replacement project, public improvements around the site should include a detached sidewalk and tree lawn on Fenton Street and W. 30`h Avenue. West 291h Avenue is a collector street, so the Streetscape Design Manual (SDM) applies to this portion or roadway. Please refer to the street sections distributed at the meeting and to Chapter 3 of the SDM for design standards and guidelines. (SDM available for download: http://www.ci.wheatridge.co.us/index.asnx?NID=431) Restoration of other surrounding streets due to damage or pipe replacement will need to be further discussed with the Public Works Department. The City's goal is to achieve full street sections in this neighborhood. Please note that per Section 26-502, all property owners in the City are responsible for maintenance of landscaping within the portion of the public right-of-way between the back of the curb or street pavement and adjacent private property. Access The vehicular entrance off W. 301h Avenue will need to be moved. Two options include: A) to the west, to align with Gray Street, or B) to the east, to be located mid -block. 6 Major Grading/Fill Permit Dumping, landfill and/or extraction operations which exceed twenty thousand (20,000) cubic yards is allowed only by Special Use Permit (see process above). A Major Grading/Fill Permit may be issued upon and in conformance with a Special Use Permit. The applicant will be required to meet specific performance standards relate to haul routes, fencing, erosion control, drainage, bond, insurance, and hours of operation. Please see the attached permit application for more information.

This is an important project for Denver Water and its customers in the surrounding community. This letter includes a brief description of the site and the project. Facility Histor The two reservoirs at Denver Water's Ashland Facility at 29`''' Avenue and Fenton Street were some of the first treated water reservoirs in the metro area and date back to the 1890's. When first constructed, these reservoirs were open to the air with an earthen bottom. In the 1910's and early 1920's the reservoirs were modified with the addition of a concrete floor and side slopes and a wooden roof. In the mid 1960's and early 1970's the wood roof was replaced with a precast concrete roofing system and has since been maintained in this configuration. See attachment for existing site plan. The aging concrete in the basins experience significant leakage through cracks which carries with it a potential for infiltration into the reservoir that could result in contamination and other related water quality concerns. Additionally, significant cracking and spalling of the precast roof members in the East Basin have left some internal prestressing cables exposed. The exposure of these prestressing roof cables will lead to accelerated corrosion, which in turn could lead to structural failures. A repair of deteriorated precast double -tee roof members was attempted in the 1990's but was unsuccessful. Reason for Reolacement The reservoirs at this site have reached beyond the end of their useful life and continued repair of the existing structures is impractical. Additionally, it has been determined that the existing 41 million gallons (MG) of storage is too large and can be reduced to 20 MG. Too much storage in a reservoir can also cause water quality concerns because it sits too long. ATTACHMENT 2 Proposed Improvements and Challenges The primary component of this project is the demolition h Seel ting reservoirs for proposed construction of two 256 foot diameter concrete water tanks. tank layout. Additional project components are listed below: • Replacement of a Filling Valve Vault at 301" Avenue and Fenton Street will move it from the public right-of-way onto the Ashland property. • Demolition of the Well -House structure and construction of a new water quality monitoring station (WQMS). The WQMS will provide for remote monitoring of conductivity, pH, chlorine, and turbidity. This new WQMS will be located on-site and may be either a vault or small building. • Replacement of off-site transmission piping dating back 1918 in the area surrounding the reservoir site (south on Fenton St. to 26"' � Avenue and east on 29`" Avenue to Sheridan Blvd). • Replacement of drainline piping in Gray Street south of 29t' Avenue. • Construction of Valve Vault at the intersection of 29`" Avenue and Depew Street. • Construction of storm sewer improvements to provide the required collection and detention of stormwater for the Ashland site and conveyance to the public storm sewer. • New security fence around the entire site. roads and other surface improvements. • Landscaping, berms, parking lot, service Successful completion of this project will require that a number of challenges be dealt with. Many of these challenges stem from the age of the reservoirs, proximity to residents, and lack of construction and staging areas. A list of items to consider is presented below: • Due to operational demands, one basin will need to remain in operation at all times during construction. Beginning with the demolition and construction of the West Tank is the most logical given the site constraints. This will limit the on-site storage to 10 MG during construction of the East Tank. • The reservoir height has been established to meet hydraulic and site constraints and considers both the visual impact to the surrounding community and the extent and impact of resulting off-site transmission main replacement. Significant public comment and concern is expected due to the magnitude of the project. Impact to surrounding neighbors includes construction noise, potential for dust and large volume of trucking. A public relations effort that educates the affected public on key issues prior to construction will be implemented. The lack of space at the site available for earthwork operations and construction staging will result in large volumes of trucking traffic to transport material off-site to stockpile excavated soil. Use of off-site property for stockpiling and storage will need to be located and coordinated with the respective jurisdictions. The selected site will require a pre -determined haul route approved by the City of Wheat Ridge. Use landscaped berms to reduce the visibility of the exposed roofs from adjacent property owners and neighbors. In addition to the reduction in visibility due to landscaped berms, the visibility will also be reduced significantly because the proposed tank roofs will be much smaller than the existing basin roofs. Potential historical documentation of Well -House prior to demolition. Significant amount of groundwater, both natural and from the existing east storage basin that will require dewatering operations. • Asbestos abatement and soil and groundwater contamination - See below under 'Environmental Concerns'. • Consider opportunity for on-site processing of demolished concrete. Items for consideration include the potential for reuse of the demolished concrete, potential noise and dust concerns, and the availability of space for such an operation. • Stability of the center berm during construction of the new west basin. • Study the feasibility of a potential hydropower station at this site. Due to the complexity of this project and the many issues where early contractor input is desirable, a Construction Manager at Risk (CMAR) approach will be used. The Construction Manager (CM) will act as a consultant during the design phase but as the equivalent of a general contractor during the construction phase. It is projected a CMAR will be on board prior by the Fall of 2011. This arrangement will allow for realistic discussions on construction concerns with the City of Wheat Ridge and other stakeholders far in advance of actual construction. Stakeholders Below is a list of stakeholders and their likely concerns: • City of Wheat Ridge o Concerns of its citizens - see below. c Restoration of any damaged street surface. o Handling of site runoff and sediment control during construction. o Wheat Ridge has a desire to straighten 29'" Avenue along the southern boundary of Ashland and push the ROW to the north to match the ROW boundary on the east side of Fenton Street. See attached document showing two potential straightening alternatives. Review of proposed stormwater collection system required for the site. o Construction traffic and haul routes. • Other surrounding municipalities (C&C of Denver, Mountain View Lakeside, Edgewater) o Impact to traffic depending on routes chosen for hauling of material to and from the site. • Colorado Department of Public Health and Environment (CDPHEJ c Conformance of the facility to CDPHE design standards. c Proper discharge of stormwater and groundwater including proper disposal of any contaminants found (see Environmental Concerns below). o Proper handling and disposal of any contaminants found in the soil (see Environmental Concerns below). c Proper handling and disposal of any contaminants found within the existing tank structure, e.g. sealants (see Environmental Concerns below). Proper air pollution reporting and permitting related to construction activities. Residents/Nursino Home surrounding the site c Visual impact of improvements. o Construction impact - noise, dust, trash, safety. c Impact to traffic, parking or access to their homes. 24 hour access by emergency vehicles to Nursing Home. Up to date information on the project during construction. Denver Water o Tank structures that will minimize or eliminate leakage and prevent infiltration of contaminants into the water distribution system for 50+ years into the future. Ability to easily operate the facility and adjoining transmission mains including remote operation. o Ability to remotely monitor water quality within the tank. Provide a secured site for this important facility. o Improve hydraulic capabilities. Delivery of this project on time and on budget. Environmental Concerns Petroleum Contamination Soil and groundwater petroleum contamination from the DSH Discount Food &Gas site located at 5795 West 29th Avenue is known to exist in the area around 29`h Avenue and Fenton Street. Concentrations of methyl tert-butyl ether (MTBE) well in excess of the Colorado Department of Labor and Employment, Division of Oil and Public Safety Risk - Based Screen Level (OPS RBSL) have been found. Additionally, one sample showed concentrations of benzene that was slightly higher than the OPS RBSL. This contaminated soil and groundwater will likely be encountered during replacement of off-site transmission mains to the east and south. Although the contamination is down gradient from the site, the removal of leaking water from the existing reservoirs and the dewatering required for the excavation of the new east reservoir could change the direction of the groundwater plume bringing contaminated water onto the site. A modified environmental site assessment (MESA) will be prepared to identify recognized environmental conditions (RECs) in connection with the Ashland Reservoir Facility and along the proposed conduit replacement corridors. A materials management plan describing the procedures to ensure appropriate handling and disposal of potentially contaminated soil and groundwater that may be encountered during the project will be prepared. The use of a grout curtain to provide a barrier between contaminated groundwater and the tank excavation will be considered. This could solve the problem of pulling contaminated groundwater onto the Ashland site however; contaminated soil and groundwater may still be encountered with any off-site transmission main improvements. Existing In -Tank Sealants Sealants in the floor/wall interface and around the perimeter of the columns have tested positive for asbestos. These sealants will be quantified and required handling and disposal requirements will be prepared. Preliminary Schedule The design, public comment and permitting period is scheduled to last approximately 17 months beginning in April, 2011. Construction for this project is estimated at 36 months beginning in Fall of 2012. We appreciate your consideration and look forward to meeting with you to discuss this important project. Should you have any questions, please contact me at matt. turney0denverwater oro or at 303-628-6523. Respectfully, Matt Turney, P.E. Denver Water Engineering - Programs and Projects i Attn: Mrs. Meredith Reckert City of Wheat Ridge Community Development 7500 W 291h Avenue Wheat Ridge, CO 80033 RE: Denver Water Ashland Reservoir Replacement Project Dear Mrs. Reckert: Denver Water has received the Pre -Application Meeting Summary completed by the Wheat Ridge Community Development Department dated July 28, 2011 for the Ashland Reservoir Replacement project. This document recounts Denver Water's description of the existing site conditions and the proposed improvements. The summary also describes the development review process and highlights certain development standards or public works standards that would typically apply to a project of this nature. Denver Water has reviewed the summary and offers the following comments: • As indicated in the meeting, the storage capacity of the Ashland treated water reservoirs will be significantly reduced (to approximately one-half of the existing volume), which will reduce the area of exposed tank roof on the site. This will also allow us to lower the site grades in the area just northwest of W. 29th Avenue and Fenton Street to closer to street grade. • Denver Water will include landscaping that will greatly improve the view of the site for those surrounding the property. We also plan to pull the fence off of the property line in some locations and increase the amount of landscaping on the exterior of the fence. • It was discussed in our last meeting that Denver Water may request a variance to the requirement that all driving surfaces be paved in some fashion. After some additional consideration, Denver Water now plans to include asphalt paved surfaces for areas subject to routine vehicular traffic. • It currently appears that Denver Water will not request the use of W. 29th Avenue to the west of Gray Street as a haul route. As offsite disposal and staging areas are identified we will propose haul routes for Wheat Ridge's consideration. • Fenton Street and W. 30th Avenue along the Denver Water property frontage will be improved with detached sidewalk and tree lawn in accordance with Wheat Ridge Public Works standards. The power lines along Fenton Street may affect the type of plantings used. A T 1 A CHMENT 3 We plan to restore damage to surrounding streets caused by'tonstruction activity. This will include damage caused by off-site pipeline installation and construction traffic in and out of the project site. Denver Water plans to inventory streets prior to construction to assess pre-existing conditions. At this time, Denver Water does not anticipate funding full street section improvements to areas not damaged by Denver Water activity. Current plans represent a 61 foot wide Right of Way (ROW) section for W. 291h • Avenue. This will require that an approximately 24 foot strip of Denver Water property along the W. 29th Avenue frontage become public ROW. Wheat Ridge has also expressed interest in having W. 29th Avenue at this location be realigned to straighten the centerline. Denver Water continues our position that we are only responsible for public ROW improvements along the adjacent property frontage. The straightening of W. 29' Avenue would require improvements outside of these limits. Denver Water would like to propose an agreement where each entity pays its share for design and constru'ctioD const uctioater � cloulike to see ld potentially `heat be carr ge take the lead on the design effort; however out as a part of the Ashland Reservoir Construction Contract. In regards to the on-site processing of demolished concrete, we share Wheat Ridge's concern in such an operation. We plan to continue to investigate the feasibility of this effort at this location however we will only present this option to Wheat Ridge if we feel the noise and dust can be controlled and there is a clear benefit to the community such as significant reduction in truck traffic in and out of the site. Per your comments, we plan to locate the north entrance off of W. 30th Avenue to align with Gray Street. Although we feel that we can comply with most of the development standards we • anticipate the following variance requests: o Denver Water will request a variance from the maximum 6 -foot height fence requirement to allow 8 -foot ornamental fencing. Water Utilities have been designated Critical Infrastructure and Key Resources (CIKR) by the U.S. Department of Homeland Security Presidential Directive (HSPD-7). As such, Denver Water has adopted enhanced -level security guidelines as it pertains to perimeter fencing at key facilities. It has become our standard to utilize 8 -foot fencing to further deter unauthorized access where amperingo could lead to disruption or contamination of the water supply. appropriate for aesthetic reasons, DfencerWater p oducthas also opted to installas opposed to standard the chain link more decorative ornamental fencing. o Denver Water will request a variance from the restriction of work hours between 7:00 a.m. to 5:00 p.m. dprohibiting � n weekends d holidays. Construction, for part, will be restricted to Monday however, we anticipate through Friday between 7:00 a.m. and 5:00 p.m., longer work hours and weekends, during both the large slab and deck concrete placements for each tank (4 occasions). This is due to the need to place and finish the slabs e the volumeof concrete necessary for the one l weekend may be required because above deSL jed pours may require one or me concrete plants dedicated to the placement. Denver Water would propose to set up viewing areas around the perimeter of the site for the public during these events. We also will need the ability to work on some Saturdays for make-up days due to weather. o Denver Water will request a variance to the 30 foot setback requirement along Fenton Street. This will apply for approximately 67 feet where the eastern tank edge will have a setback distance of between 26 and 30 feet (see attached setback exhibit). In this same area we are also proposing a small retaining wall that will be located approximately 2.5' off of the property line behind the fence. The primary driver for requesting the setback variance is to minimize the construction impacts to the residential units to the west of the Ashland site. The proposed location and spacing of the tanks will allow most of the existing west berm to stay in place, thus decreasing the construction impact to the residences to the west of the Ashland site. Additionally, the distance between the tanks is the minimum allowable to enable future maintenance of the tanks. Please note that the proposed setbacks for all other areas on all sides of the property will be much larger than the current setbacks to the existing larger tanks. In spite of the slightly reduced setback along Fenton at this location, the proposed site plan will dramatically improve the appearance of the site from Fenton by reducing the quantity of exposed retaining wall along the property line from 1567 square feet to 180 square feet. o Denver Water will request a variance to the requirement that non-residential uses located adjacent to residentially zoned areas or agriculturally zoned areas provide a screened or landscaped buffer area. Since the proposed and existing embankments will serve as an effective barrier to screen the view of the Denver Water facilities from the adjacent residential lots to the west and to the south we do not believe additional screening will be necessary. Currently a 30% design package is anticipated to be complete by late 2011. Additionally, we have recently selected Western Summit Constructors Inc. to serve as our Construction Manager to offer their expertise during the design phase. Their input will allow us to plan the project with more detail and communicate that plan to Wheat Ridge and those that will be affected by this project. Thank you for your attention to this project. We look forward to working with you to understand the concerns of Wheat Ridge and its' citizens and working to reduce the impact this project has on the community as much as possible. Please let me know if you have any questions or comments. Respectfully, Matt Turney, P.E. 2nver Water cngineering - Programs and Projects December 20, 2011 Dear Neighbors of Ashland Reservoir: Denver Water plans to improve the safety and reliability of its Ashland Reservoir site by building two new underground water storage tanks. The design for the site is being developed and construction is scheduled to begin in fall 2012. Neighbors will notice more activity at the site as Denver Water staff members and contractors visit the site as part of the design process. Western Summit has been hired by Denver Water as the construction manager for the project. As part of a phased project, Western Summit will demolish one of the two existing tanks and build a new tank in its place. Once that tank is in service, the second tank will be demolished and another tank built in its place. The two tanks cannot be demolished at the same time because the water stored at the site is needed for customers and for fire protection. The entire project is scheduled to run through 2015. The contractor for the project will be required to follow work hours, as set forth by the City of Wheat Ridge. Denver Water staff has met with representatives from the City of Wheat Ridge to discuss the project. As the project proceeds, Denver Water and its contractors will continue to meet with city staff to discuss potential impacts, and mitigation plans, for the project. Large portions of the berms on the west and east sides of the site will be kept in place to reduce noise from demolition and construction. Part of the south berm will be removed initially for access to the site off of 29thAvenue. Additional sections of the south berm may be removed for use as a storage area for the project. Additional information, a site map and a photo simulation of the site are available at www.denverwater.org/ashland. Once completed, the site will appear different from the existing site. The new tanks will be circular and smaller than they are now. The new tanks will have a smaller footprint, which will create a larger landscaped area on the south side of the property. The existing chain link fence will be removed and will be replaced by a black, 8 -foot - high ornamental steel fence. The City of Wheat Ridge will require Denver Water to go through a Special Use Permit (SUP) process prior to finalization of the design of the site. There will be a pre -application neighbor- hood meeting required as part of the SUP process. If residents have questions about the SUP process, they can contact Meredith Reckert, at 303-235-2848 or mreckert@ci.wheatridge.co.us. Updates on the project will be posted at www.denverwater.org/ashland. Please contact me if you have any questions or concerns.

Denver Water has reviewed the summary and offers the following comments: • As indicated in the meeting, the storage capacity of the Ashland treated water reservoirs will be significantly reduced (to approximately one-half of the existing volume), which will reduce the area of exposed tank roof on the site. This will also allow us to lower the site grades in the area just northwest of W. 29th Avenue and Fenton Street to closer to street grade. • Denver Water will include landscaping that will greatly improve the view of the site for those surrounding the property. We also plan to pull the fence off of the property line in some locations and increase the amount of landscaping on the exterior of the fence. • It was discussed in our last meeting that Denver Water may request a variance to the requirement that all driving surfaces be paved in some fashion. After some additional consideration, Denver Water now plans to include asphalt paved surfaces for areas subject to routine vehicular traffic. • It currently appears that Denver Water will not request the use of W. 29th Avenue to the west of Gray Street as a haul route. As offsite disposal and staging areas are identified we will propose haul routes for Wheat Ridge's consideration. • Fenton Street and W. 30th Avenue along the Denver Water property frontage will be improved with detached sidewalk and tree lawn in accordance with Wheat Ridge Public Works standards. The power lines along Fenton Street may affect the type of plantings used. C�JNSERVE We plan to restore damage to surrounding streets caused by construction activity. This will include damage caused by off-site pipeline installation and construction traffic in and out of the project site. Denver Water plans to inventory streets prior to construction to assess pre-existing conditions. At this time, Denver Water does not anticipate funding full street section improvements to areas not damaged by Denver Water activity. Current plans represent a 61 foot wide Right of Way (ROW) section for W. 29"' Avenue. This will require that an approximately 24 foot strip of Denver Water property along the W. 29`h Avenue frontage become public ROW. Wheat Ridge has also expressed interest in having W. 29th Avenue at this location be realigned to straighten the centerline. Denver Water continues our position that we are only responsible for public ROW improvements along the adjacent property frontage. The straightening of W. 29`h Avenue would require improvements outside of these limits. Denver Water would like to propose an agreement where each entity pays its share for design and construction. Denver Water would like to see Wheat Ridge take the lead on the design effort; however construction could potentially be carried out as a part of the Ashland Reservoir Construction Contract. In regards to the on-site processing of demolished concrete, we share Wheat Ridge's concern in such an operation. We plan to continue to investigate the feasibility of this effort at this location however we will only present this option to Wheat Ridge if we feel the noise and dust can be controlled and there is a clear benefit to the community such as significant reduction in truck traffic in and out of the site. Per your comments, we plan to locate the north entrance off of W. 30"' Avenue to align with Gray Street. Although we feel that we can comply with most of the development standards we anticipate the following variance requests: o Denver Water will request a variance from the maximum 6 -foot height fence requirement to allow 8 -foot ornamental fencing. Water Utilities have been designated Critical Infrastructure and Key Resources (CIKR) by the U.S. Department of Homeland Security Presidential Directive (HSPD-7). As such, Denver Water has adopted enhanced -level security guidelines as it pertains to perimeter fencing at key facilities. It has become our standard to utilize 8 -foot fencing to further deter unauthorized access where tampering could lead to disruption or contamination of the water supply. Where appropriate for aesthetic reasons, Denver Water has also opted to install the more decorative ornamental fence product as opposed to standard chain link fencing. o Denver Water will request a variance from the restriction of work hours between 7:00 a.m. to 5:00 p.m. and prohibiting work on weekends and holidays. Construction, for the most part, will be restricted to Monday through Friday between 7:00 a.m. and 5:00 p.m., however, we anticipate longer work hours and weekends, during both the large slab and deck concrete placements for each tank (4 occasions). This is due to the need to place and finish the slabs during one continuous work shift. Work on the weekend may be required because the volume of concrete necessary for the above described pours may require one or more concrete plants dedicated to the placement. Denver Water would propose to set up viewing areas around the perimeter of the site for the public during these events. We also will need the ability to work on some Saturdays for make-up days due to weather. o Denver Water will request a variance to the 30 foot setback requirement along Fenton Street. This will apply for approximately 67 feet where the eastern tank edge will have a setback distance of between 26 and 30 feet (see attached setback exhibit). In this same area we are also proposing a small retaining wall that will be located approximately 2.5' off of the property line behind the fence. The primary driver for requesting the setback variance is to minimize the construction impacts to the residential units to the west of the Ashland site. The proposed location and spacing of the tanks will allow most of the existing west berm to stay in place, thus decreasing the construction impact to the residences to the west of the Ashland site. Additionally, the distance between the tanks is the minimum allowable to enable future maintenance of the tanks. Please note that the proposed setbacks for all other areas on all sides of the property will be much larger than the current setbacks to the existing larger tanks. In spite of the slightly reduced setback along Fenton at this location, the proposed site plan will dramatically improve the appearance of the site from Fenton by reducing the quantity of exposed retaining wall along the property line from 1567 square feet to 180 square feet. o Denver Water will request a variance to the requirement that non-residential uses located adjacent to residentially zoned areas or agriculturally zoned areas provide a screened or landscaped buffer area. Since the proposed and existing embankments will serve as an effective barrier to screen the view of the Denver Water facilities from the adjacent residential lots to the west and to the south we do not believe additional screening will be necessary. Currently a 30% design package is anticipated to be complete by late 2011. Additionally, we have recently selected Western Summit Constructors Inc. to serve as our Construction Manager to offer their expertise during the design phase. Their input will allow us to plan the project with more detail and communicate that plan to Wheat Ridge and those that will be affected by this project. Thank you for your attention to this project. We look forward to working with you to understand the concerns of Wheat Ridge and its' citizens and working to reduce the impact this project has on the community as much as possible. Please let me know if you have any questions or comments. Respectfully, OZ5,c_� �� Matt Turney, P.E.

North of the park and east of the gardens Denver Water owns a three -acre site, on top of which the soccer fields are located: "Beneath this permeable grass and soil roofing, about two feet thick, lie twin underground storage reservoirs (Basins No. 1 and 3) holding tens of millions of gallons of treated or potable water supply --"finished water" in the language of water engineers. By mutual agreement between the City and County of Denver and its quasi -independent Board of Water Commissioners visitors may play on public lands above an artificial underground lake." Denver Water also owns the adjacent site to the east where a recycled water storage tank exists. A community garden was recently relocated to this property. See attached image. Happy Friday!

Page] of 2 Meredith Reckert From: Mark Westberg Sent: Tuesday, January 18, 2011 3:46 PM To: Meredith Reckert Cc: Steve Nguyen; Dave Brossman; Russ Higgins; Bill LaRow; Tim Paranto Subject: Asland Reservoir Reconstruction Mere Denver Water is proposing to do the following: 1. Completely remove the existing tanks, 41 million gallon capacity. 2. Construct two new circular tanks, 10 million gallon capacity each. 3. Replace water lines between tanks and pumping station at Sheridan. Lines are 16 feet deep. 4. Replace some water lines at 30th and Fenton. 5. Replace some of the drain line that crosses 29th and continues down Gray. 6. Start construction in Fall 2012, last 3 years. We might want to consider the following public improvements: 30 Avenue — Add a sidewalk w/ amenity zone on south side adjacent to DW facility. There is around 8' between their fence and the existing curb. However, their fence appears to encroach into our ROW by around T, so if the fence is moved to the property line, then plenty of room. ROW is more than adequate at 60'. Asphalt width is more than adequate at 40'. Fenton Street —This street is on our BlkePed map as a shared lane facility so typically would need X -sec L2P with 2 lanes, a shared bike/parking lane, amenity zone, and sidewalk. The existing pavement is 32' wide, so it is adequate, however; there are always cars parked along both sides of this street because of the assisted living facility on the east side, so might want to consider additional width for separate bike lanes or possibly a multi -use path instead of a sidewalk. The west side would be a good location for a multi -use path, since there are no driveways. There is 16' of ROW behind the curb, so adequate room for a 10' path and 6' amenity zone. 29th Avenue — This is a collector street that is currently substandard. The street also jogs south because of the slope at the south end of the DW facility. Since this slope can be removed, it would be advantageous to realign the street and build to X -sec C3 standards, 3 lanes with sidewalks and amenity zones. The existing ROW is 60', however; there is 65' of ROW to the east and west, so an additional 5' should be obtained. This allows full implementation of the C3 X -sec between Fenton and Gray Streets. Other comments: 1. Stormwater - Since this is a complete reconstruction, a detention pond with water quality will be required. There is a storm sewer in Gray Street that could accept the discharge. I mentioned that Full Spectrum would be okay. This would remove 6.5 acres from being undetained and untreated. 2. The other Stormwater — Since the site is well over 1 acre, a State Permit and SWMP will be required. 3. SUP for major grading — DW knows that this will be required. 4. Other land use process — We cautioned them that other land use processes may be require, typical timeframe of 6 to 9 months. They have not picked their consultants yet and would likely like to have a pre -Pre -App to discuss what will be required so that they can include everything in their scope of work for their consultants. 5. impacts — DW seemed very cognizant of the potential impacts, both during and after construction that this facility will have on the adjacent residential. 6. ROW Permits — We discussed ROW permit issues at length including Materials Use Tax, haul routes, damage to streets, etc. 1/18/2011 City of ]��Wh6atRidpFe LAND USE CASE PROCESSING APPLICATION Community Development Department 7500 West 291h Avenue • Wheat Ridge, CO 80033 • Phone (303) 235-2846 (Please print or type all information) Applicant Denver Water City Denver Owner Denver Water City Denver Address 1600 West 12th Ave State CO _Zip__8 0204 Address 1600 West 12th Ave State CO Zip 80204 Phone303-628-6000 Fax Phone 303-628-6000 Fax Contact Martin Garcia Address 1600 West 12th Ave Phone 303-628-6631 City Denver State CO Zip802O4 Fax (The person listed as contact will be contacted to answer questions regarding this application, provide additional information when necessary, post public hearing signs, will receive a copy of the staff report prior to Public Hearing, and shall be responsible for forwarding all verbal and written communication to applicant and owner.)
