The plat still is still in need of some minor modifications before Mylar®, so I would suggest that they send us one more PDF to review prior to plotting. Please note the Final Drainage Report/Plan and Civil Construction Plans are approvable. I've already been in contact with Jerry Davidson, P.E. regarding getting me the signed & sealed documents and PDF (hardcopies are needed for the BPA plan sets), but he will be out of town until the 18th so he can't get them to me before that. But we should be fine as far as timing and Building Permit sign -off goes. Jerry is aware of the outstanding items for the plat and that it will still need to routed for signatures, etc. when it's in an approvable condition prior to recordation (which has to occur prior to BPA sign -off).

The new clinic will be a marvelous addition (expansion?) to the services available for the City of Wheat Ridge and metropolitan area. You do have options for temporary signage announcing your new home. Construction signs — typically announce the proposed new use and contractor(s) doing the work — They are freestanding, cannot exceed 32 square feet in size and 7' in height, setback 5' from property lines. These are usually put up once construction starts. No permit is required and you are allowed one per street front (43`d Avenue and 44th Avenue). Temporary banners are also allowed — These would probably work for your "coming soon" announcement — they are allowed to be put on building walls but cannot be attached to fences or landscaping. The size allowance is % square foot of signage for every linear foot of wall to which the banner is attached — in a nut shell, if the linear footage of the wall is 50', then a 25 square foot banner could be erected on it. Again, no permit is required and you are allowed one per street front (43`d and 44th Avenue). Let me know if you have any questions — I look forward to construction starting for the project.

Dear Mr. Davidson, I have completed the third review of the above referenced documents received by Public Works on March 7, 2016, for the proposed commercial development at the property located at 10163 W. 43`d Avenue, and I have the following comments: PLANNING & ZONING: Site Development Plan: 1. All previous Public Works comments have been addressed; the SDP is approvable from a PW standpoint. CIVIL ENGINEERING: Final Drainage Report (Discussion): 1. Please provide the overall area of the project under the Introduction (Site Description) section. 2. Under the Historic Drainage System, Sub -Basin and Site Drainage section it needs to be clarified that this drainage information is for Lots 1 & 2, Onyx Park Sub only and does not include any drainage info for the northerly portion of the project, being Lot 1 of Kelly Sub Filing No. 1. Furthermore, the drainage from the northerly portion needs to be analyzed and the historic info provided in this section of the narrative. 3. The following comments pertain to Section 4 C. Detention: a. Please modify the first paragraph. Per the City's Site Drainage Requirements, no flood attenuation detention is required due to the subject property lying immediately adjacent to Clear Creek, a major drainageway. Relief from the detention requirement has nothing to do with the floodplain, please revise this statement. b. The City highly discourages pumps and has not approved such a design in more than 20 years. Please note that if a design incorporating a pump system will be proposed, also www.ci.wheatridge.co.us Public Works Engineering March 11, 2016 Page 2 discuss in detail the design for a complete back-up system which shall include a generator. c. Discuss how the percolation tests were performed, e.g., number of tests holes, depth of the holes, depth of the local water table, etc. Also include all test data in the Appendix. d. Need to include a statement that a minimum of one (1) foot of freeboard has been provided in the design, and include the WSEL,00 and top of wall elevations to support the statement. e. For the New Sand Filter WQ facility, discuss: Ji. If the Facility will employ Full Infiltration, Partial Infiltration, or No -Infiltration, as defined by the UDFCD, and ii. The use of an underdrain and its connection, and also the placement of a clean- out. f. It is stated that the time to drain the EURV will be 8.64 hours. Please provide the anticipated drain time for the 100 -year event. g. Please note the following: If the percolation test data is sufficient and water table is deep, maybe the proposed infiltration basin can handle the volume for the 100 -year event. If this is the case you do not need to include the EURV; just use the 100 -year volume for the basin. The City will then review this design as if it were an underground facility (using those criteria), and the release rate will be the bottom area of the pond multiplied by the average percolation rate. This is the primary reason we require a minimum of 2, and preferably 3, perc tests completed (to obtain the average rate) within the area of the pond. Refer to the info under Average Percolation Rate and the associated Notes on page 5 of the Site Drainage Requirements. 4. Under Section 4 Conclusions: a. This section needs to be renumbered to Section 5 (Section 4 is the Proposed (Developed) Drainage System section). b. The Conclusion should include a comparison of the historical runoff rates from the site (including from the northerly area) versus the developed release from the site. If the new basin on the north end is able to handle the 100 -year volume, the runoff from the northerly portion of the site will be reduced to near zero. This information should be conveyed to the reader as hard evidence that this design will greatly enhance the drainage conditions. 5. Please provide a wet seal and signature on the Report, and deliver one hardcopy along with one PDF of the revised, signed & sealed Report for approval. Final Drainage Report (Appendix): 1. Need to include historic runoff calculations for the northerly portion of the project (Lot 1, Kelley Sub). This information can then be compared with the developed (detained) runoff in the narrative as an example of how this design is beneficial to the existing City storm sewer system. 2. For Basin B please include the UDFCD worksheet for the "Stage -Storage Sizing for Detention Basins". You can directly enter the storage requirement for the major storm + WQCV event from the Full Spectrum worksheet. 3. Include the percolation test data along with any (site specific) geotechnical information. In order to be approvable, any design utilizing infiltration must have percolation tests performed at each specific location. A minimum of 2 (and preferably 3) tests shall be required at each proposed detention/sand filter location. www.ci.wheatridge.com s 10163 W43rdAve_WhealRidgeAnimalHospital-Review-3.Itr.docx Public Works Engineering March 11, 2016 Page 3 Final Drainage Plan: 1. Identify the pipe coming from the inlet on the west side of the north entrance drive and the outfall to the "New EURV Detention Facility". 2. Provide the grade and elevations for both the emergency overflow weir and sidewalk chase (at FL). 3. Please provide the following elevations for the "New EURV Detention Facility": a. The bottom of the New EURV pond. b. WSELIoo. c. The top of wall elevation. 4. Need to include a Historic Drainage Map depicting the existing conditions for the ENTIRE project site. 5. Please note the following: a. No drainage facilities shall be constructed or grading associated with drainage facilities shall occur within two (2) feet of any property boundary line. b. All drainage facilities shall be fully encompassed by a "STORMWATER DETENTION EASEMENT" to be clearly identified on all plan sheets. c. Include the following Note on the Drainage Plan: "THE STORM DRAINAGE FACILITIES WITHIN THE AREA HEREIN SHOWN AS "STORM SEWER EASEMENT" SHALL BE CONSTRUCTED AND MAINTAINED BY THE OWNER AND SUBSEQUENT OWNERS, HEIRS, SUCCESSORS AND ASSIGNS. IN THE EVENT THAT SUCH CONSTRUCTION AND MAINTENANCE IS NOT PERFORMED BY SAID OWNER, THE CITY OF WHEAT RIDGE SHALL HAVE THE RIGHT TO ENTER SUCH AREA AND PERFORM NECESSARY WORK, THE COST OF WHICH SAID OWNER, HEIRS, SUCCESSORS, AND ASSIGNS AGREES TO PAY. NO BUILDING OR STRUCTURE WILL BE CONSTRUCTED IN THE DETENTION AREA AND NO CHANGES OR ALTERATIONS AFFECTING THE HYDRAULIC CHARACTERISTICS OF THE DETENTION AREA WILL BE MADE WITHOUT THE APPROVAL OF THE DIRECTOR OF PUBLIC WORKS." 6. What's the dark line represent on the existing detention facility on the easterly side? How does stormwater enter this facility, is there a curb -cut? If so, please identify on this Plan. 7. Describe how does stormwater enters the existing water quality facility on the south (e.g., curb - cut, etc.). 8. Provide the top and bottom elevations for the existing water quality facility on the south. 9. Please identify the "New Sand Filter WQ Facility". If a curb -cut is proposed to allow flow from the parking lot into the facility is proposed, please identify this or these on the Drainage Plan sheet. 10. Please include details on this Plan sheet for both the New Sand Filter WQ Facility and for the proposed underdrain for the Sand Filter. (Include an additional Detail Sheet as necessary). Note: Please include a clean-out for the underdrain. 11. Include on this Plan to -scale cross-sections A -A through C -C at the locations shown herein. 12. Please provide a wet seal and signature on a hardcopy of the Plan, and deliver the hardcopy along with one PDF of the revised, signed & sealed Plan for approval.

CDPS Permit & Stormwater Management Plan: This site in general is greater than one acre in size and the area of disturbance will meet or exceed one (1) acre, so a Stormwater Management Plan (SWMP) associated with the required State CDPS Permit shall be submitted to the City of Wheat Ridge for review and approval. The SWMP must be approved by the City prior to issuance of any Demolition, Grading, or Building Permits. The CDPS Permit is generally obtained from the Colorado Department of Public Health and Environment by the contractor at time of Building Permit Application. A copy of the CDPS must accompany the final submittal of the SWMP. Please contact Bill LaRow, Stormwater Program Manager at 303.235.2871 for further information). It is highly recommended that the SWMP be submitted as soon as possible to avoid delays in the issuance of required Permits. 7. Drainage Certification/ Stormwater Maintenance Agreement and O & M Plan: Please note the following items required prior to the issuance of the Certificate of Occupancy: a. Drainage Certification: A Drainage Certification Letter from the Engineer -of -Record stating that all drainage related items were constructed per the approved civil engineering documents. The Certification Letter shall be accompanied by As -Built plans in support of the statements made in the Letter as required by the Municipal Code of Laws. b. Stormwater Maintenance Agreement and O & M Plan: 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 stormwater quality facilities including, but not limited to, above -ground or underground detention facilities, porous landscape detention areas, porous pavement, centrifuge type devices such as a Rinker Stormcepter®, hydrodynamic separation systems such as a Contech Vortechs®, or for any other approved post -construction BMP, a Stormwater Maintenance Agreement accompanied by an Operations and Maintenance (O & M) Schedule/Log shall be required prior to issuance of the Certificate of Occupancy. The O & M Schedule/Log must be kept current and will be inspected on a regular basis by City staff to ensure compliance with City of Wheat Ridge Municipal Code requirements. Please note that there are three (3) separate and distinct stormwater post BMPs on this site, and as such the O & M shall reflect maintenance requirements for ALL three of these. 8. Fees in Lieu of Construction: Public Improvements meeting the current standard six (6) foot detached sidewalk with a six (6) foot amenity zone are required for all new development and redevelopment projects along commercial corridors such as W. 44th Avenue. The existing Public improvements along the West 44th Avenue frontage of the subject property do not meet the current standards. As such, the current standard improvements shall be required to be either constructed with this project or fees may be taken in lieu of construction. Since the design for the eastbound approach to the Kipling Street intersection is not yet complete, the Public Works Department recommends fees be taken in lieu of construction. Fees in the amount of $4,597 are required for the detached 6' sidewalk only (existing curbing will remain). The fees will be due prior to prior to the recordation of the approved Final Plat. 9.

Keep in mind that the drainage report is not approvable yet however, and until it is approved there is always the possibility that the geometry of the northerly pond could change. They made some wrong assumptions when they did the perc tests, so I'm going to make them redo them. They will be going much deeper than they originally did (by about 6'), which may cause them to find the water table. If that should happen they will need to raise the pond bottom, which in turn will cause the facility to enlarge. This is the geometry change I refer to. But I wanted to let you know that otherwise they've addressed all previous PW comments if you want to keep them moving forward. (I wasn't sure how much the site could change before we have to pull the plug on the SDP moving forward, so I wanted to warn you about the possible change to the pond). 0 David F.

Fees in Lieu of Construction: Public Improvements meeting the current standard six (6) foot detached sidewalk with a six (6) foot amenity zone are required for all new development and redevelopment projects along commercial corridors such as W. 44t1i Avenue. The existing Public improvements along the West 44`h Avenue frontage of the subject property do not meet the current standards. As such, the current standard improvements shall be required to be either constructed with this project or fees may be taken in lieu of construction. Since the design for the eastbound approach to the Kipling Street intersection is not yet complete, the Public Works Department recommends fees be taken in lieu of construction. Fees in the amount of $4,597.00 are required for the detached 6' sidewalk only (existing curbing will remain). The fees will be due prior to prior to the recordation of the approved Final Plat. www.ci.whentridge.co. u s 10163 W43,dAve_WheatRidgeAnima[Hospital - Review-2.1indocx Public Works Engineering December 29, 2015 Page 4 Information pertaining to the Public Works development requirements, Site Drainage Requirements, the City's Street Construction Standards & Details in AutoCAD® DWG format, ROW maps, and City -based coordinate and land surveying information (i.e., Current City Datum), is all available on the Public Works, Development Review page of the City of Wheat Ridge website at: www.ci.wheatridge.coms The above comments are as of the date reviewed and may not reflect all comments from other departments or reviewing agencies.

The Fruitdale Sanitation District has no objections with the proposed rezoning and specific development plan conditional on the items identified herein are fully addressed. The following are general requirements for sanitary sewer service. The subject lot is entirely within the service and boundary area of the Fruitdale Sanitation District. Treatment of sewage generated within the Fruitdale Sanitation District is provided by Metro Wastewater Reclamation District. Existing District Sanitary Sewer Mainline(s) Fruitdale Sanitation District has the following sanitary sewer mains adjacent to the proposed property: • 18 -inch mainline running north to south, west of the referenced property within an easement. It appears the property may be serviced by gravity flow; however, the homeowner/developer is responsible for determining depths of the existing sanitary sewer main to verify if gravity flow is feasible or if a private individual sewage ejector (lift station) is required. The issuance of a sewer tap permit by the District does not in any way guarantee that the property can be served by gravity flow. Certified design documentation indicating the amount of flow that the animal hospital will contribute to the sanitary system is required to initially evaluate if the existing sanitary sewer system has sufficient downstream capacity. Depending on values of anticipated flow, the Owner/Developer may be required to evaluate downstream sanitary mainline capacity to show the anticipated peak flows can be accommodated by the existing main. Please note that Metro Wastewater Reclamation District's Rules and Regulations must be complied with at all times, especially refer to Section 6 "Pretreatment/Industrial Waste Control". As has been seen with several established hospital facilities, often deleterious matter is disposed of through the sanitary system. A separator (external to the building) of sufficient size to mitigate clogging of the service and mainline may be required in addition to pre-treatment requirements. Costs The amount of the sanitary sewer tap fees will be based on the water meter tap size for the proposed development. When the certified water tap size(s) is received, a tap fee document can be produced indicating tap fees required for connection to the sanitary sewer collection system, including any credits that may be available. In addition, engineering review fees may be required to be deposited in advance by the developer to the District. MARTIN/MARTIN, INC. 12499 WEST COLFAX AVENUE LAKEWOOD, COLORADO 80215 MAIN 303.431.6100 MARTINMARTIN.COM Fruitdale Sanitation District —10163 W. 43rd Ave. — WZ-15- 09 November 3, 2015 All costs involved are to be deposited in advance— engineering, reviews, design, construction, observation and inspections — are the responsibility of the Owner/Developer at the then current rate fee structure. Please be aware that proper tap and development fees are required to be paid prior to connection to the District main. A minimum 72 -hour notice prior to construction is required following District receipt of all fees. These fee amounts can be paid directly to the District Office prior to connection, payable to Fruitdale Sanitation District, which also collects Metro Wastewater's "connection fees'. Any questions regarding this document, please contact us at (303) 431-6100.

Dear Mr. Davidson, I have completed the first review of the above referenced documents received on October 28, 2015, for the proposed commercial development at the property located at 10163 W. 43'd Avenue, and I have the following comments: PLANNING & ZONING: Site Development Plan: 1. On Sheet #2, Site Plan, please note the following: a. All drainage facilities shall be fully encompassed by a "STORMWATER DETENTION EASEMENT". As such, all three of the existing & proposed facilities need to include easements clearly identified on this Site Plan. b. Include a Note containing the following language: "THE STORM DRAINAGE FACILITIES WITHIN THE AREA HEREIN SHOWN AS "STORM SEWER EASEMENT" SHALL BE CONSTRUCTED AND MAINTAINED BY THE OWNER AND SUBSEQUENT OWNERS, HEIRS, SUCCESSORS AND ASSIGNS. IN THE EVENT THAT SUCH CONSTRUCTION AND MAINTENANCE IS NOT PERFORMED BY SAID OWNER, THE CITY OF WHEAT RIDGE SHALL HAVE THE RIGHT TO ENTER SUCH AREA AND PERFORM NECESSARY WORK, THE COST OF WHICH SAID OWNER, HEIRS, SUCCESSORS, AND ASSIGNS AGREES TO PAY. NO BUILDING OR STRUCTURE WILL BE CONSTRUCTED IN THE DETENTION AREA AND NO CHANGES OR ALTERATIONS AFFECTING THE HYDRAULIC CHARACTERISTICS OF THE DETENTION AREA WILL BE MADE WITHOUT THE APPROVAL OF THE DIRECTOR OF PUBLIC WORKS.". 2. The street tree on the far northeast should be moved to the west about 15'. The Drainage Plan shows a drainage (chase) section for the emergency overflow of the detention pond running nearly through the middle of the tree at the proposed location. 3. Please be advised that a maintenance access for the pond will be required, and that in all likelihood it will be located at the west end of the pond (being the only logical location). www.ci.wheatridge.co.us Public Works Engineering November 13, 2015 Page 2 CIVIL ENGINEERING: Final Drainage Report (Discussion): 1. Please provide the overall area of the project under the Introduction (Site Description) section. 2. Under the Historic Drainage System, Sub -Basin and Site Drainage section it needs to be clarified that this drainage information is for Lots I & 2, Onyx Park Sub only and does not include any drainage info for the northerly portion of the project, being Lot I of Kelly Sub Filing No. 1. Furthermore, the drainage from the northerly portion needs to be analyzed and the historic info provided in this section of the narrative. 3. The following comments pertain to Section 4 C. Detention: a. Please modify the first paragraph. Per the City's Site Drainage Requirements, no flood attenuation detention is required due to the subject property lying immediately adjacent to Clear Creek, a major drainageway. Relief from the detention requirement has nothing to do with the floodplain, please revise this statement. b. The City highly discourages pumps and has not approved such a design in more than 20 years. Please note that if a design incorporating a pump system will be proposed, also discuss in detail the design for a complete back-up system which shall include a generator. c. Discuss how the percolation tests were performed, e.g., number of tests holes, depth of the holes, depth of the local water table, etc. Also include all test data in the Appendix. d. Need to include a statement that a minimum of one (1) foot of freeboard has been provided in the design, and include the WSEL1oo and top of wall elevations to support the statement. e. For the New Sand Filter WQ facility, discuss: i. If the Facility will employ Full Infiltration, Partial Infiltration, or No -Infiltration, as defined by the UDFCD, and ii. The use of an underdrain and its connection, and also the placement of a clean- out. f. It is stated that the time to drain the EURV will be 8.64 hours. Please provide the anticipated drain time for the 100 -year event. g. Please note the following: If the percolation test data is sufficient and water table is deep, maybe the proposed infiltration basin can handle the volume for the 100 -year event. If this is the case you do not need to include the EURV; just use the 100 -year volume for the basin. The City will then review this design as if it were an underground facility (using those criteria), and the release rate will be the bottom area of the pond multiplied by the average percolation rate. This is the primary reason we require a minimum of 2, and preferably 3, perc tests completed (to obtain the average rate) within the area of the pond. Refer to the info under Average Percolation Rate and the associated Notes on page 5 of the Site Drainage Requirements. 4. Under Section 4 Conclusions: a. This section needs to be renumbered to Section 5 (Section 4 is the Proposed (Developed) Drainage System section). b. The Conclusion should include a comparison of the historical runoff rates from the site (including from the northerly area) versus the developed release from the site. If the new basin on the north end is able to handle the 100 -year volume, the runoff from the www.d.wheatridge.co.us 10163 W43rdAve_WheatRidgeAnimalHospital - Review-Lhr.docx Public Works Engineering November 13, 2015 Page 3 northerly portion of the site will be reduced to near zero. This information should be conveyed to the reader as hard evidence that this design will greatly enhance the drainage conditions. 5. Please provide a wet seal and signature on the Report, and deliver one hardcopy along with one PDF of the revised, signed & sealed Report for approval. Final Drainage Report (Appendix): 1. Need to include historic runoff calculations for the northerly portion of the project (Lot 1, Kelley Sub). This information can then be compared with the developed (detained) runoff in the narrative as an example of how this design is beneficial to the existing City storm sewer system. 2. For Basin B please include the UDFCD worksheet for the "Stage -Storage Sizing for Detention Basins". You can directly enter the storage requirement for the major storm + WQCV event from the Full Spectrum worksheet. 3. Include the percolation test data along with any (site specific) geotechnical information. In order to be approvable, any design utilizing infiltration must have percolation tests performed at each specific location. A minimum of 2 (and preferably 3) tests shall be required at each proposed detention/sand filter location. Final Drainage Plan: I . Identify the pipe coming from the inlet on the west side of the north entrance drive and the outfall to the "New EURV Detention Facility". 2. Provide the grade and elevations for both the emergency overflow weir and sidewalk chase (at 170- 3. Please provide the following elevations for the "New EURV Detention Facility": a. The bottom of the New EURV pond. b. WSEL1oo• c. The top of wall elevation. 4. Need to include a Historic Drainage Map depicting the existing conditions for the ENTIRE project site. 5. Please note the following: a. No drainage facilities shall be constructed or grading associated with drainage facilities shall occur within two (2) feet of any property boundary line. b. All drainage facilities shall be fully encompassed by a "STORMWATER DETENTION EASEMENT" to be clearly identified on all plan sheets. c. Include the following Note on the Drainage Plan: "THE STORM DRAINAGE FACILITIES WITHIN THE AREA HEREIN SHOWN AS "STORM SEWER EASEMENT" SHALL BE CONSTRUCTED AND MAINTAINED BY THE OWNER AND SUBSEQUENT OWNERS, HEIRS, SUCCESSORS AND ASSIGNS. IN THE EVENT THAT SUCH CONSTRUCTION AND MAINTENANCE IS NOT PERFORMED BY SAID OWNER, THE CITY OF WHEAT RIDGE SHALL HAVE THE RIGHT TO ENTER SUCH AREA AND PERFORM NECESSARY WORK, THE COST OF WHICH SAID OWNER, HEIRS, SUCCESSORS, AND ASSIGNS AGREES TO PAY. NO BUILDING OR STRUCTURE WILL BE CONSTRUCTED IN THE DETENTION AREA AND NO CHANGES OR ALTERATIONS AFFECTING THE HYDRAULIC www.d.whestriftc.co.us 10163 W43rdAve_WheatRidgeAnima[Hospital - Review-Htr.docx Public Works Engineering November 13, 2015 Page 4 CHARACTERISTICS OF THE DETENTION AREA WILL BE MADE WITHOUT THE APPROVAL OF THE DIRECTOR OF PUBLIC WORKS." 6. What's the dark line represent on the existing detention facility on the easterly side? How does stormwater enter this facility, is there a curb -cut? If so, please identify on this Plan. 7. Describe how does stormwater enters the existing water quality facility on the south (e.g., curb - cut, etc.). 8. Provide the top and bottom elevations for the existing water quality facility on the south. 9. Please identify the "New Sand Filter WQ Facility". If a curb -cut is proposed to allow flow from the parking lot into the facility is proposed, please identify this or these on the Drainage Plan sheet. 10. Please include details on this Plan sheet for both the New Sand Filter WQ Facility and for the proposed underdrain for the Sand Filter. (Include an additional Detail Sheet as necessary). Note: Please include a clean-out for the underdrain. 11. Include on this Plan to -scale cross-sections A -A through C -C at the locations shown herein. 12.

INTRODUCTION A. SITE LOCATION The Wheat Ridge Animal Hospital project is located at 10055 W 43rd Avenue, Wheat Ridge. Colorado. The site spans from W 43`d Avenue northward to W 44'h Avenue. It occupies the platted lots of Lots 1 and 2 Onyx Park Subdivision Amendment No. 1 and Lot 1 Kelly Subdivision Filing No. 1. Adjacent development west consists of office buildings. Development south of the site is also an office building and parking lot. To the north are strip retail buildings and commercial retail. To the east is vacant ground and a bar. B. SITE DESCRIPTION The site is currently developed with an office building on the southerly portion of the lot, and a tree trimming business on the northerly portion. The office building portion is primarily surfaced with asphalt pavement and perimeter landscaping. The tree business is surfaced with gravel and dirt. The southwest portion of the lot is currently used for outdoor storage and is surfaced with dirt. Site topography is generally flat. Over the northern portion of the lot, and sloping mildly east over the southern portion of the lot. There are no existing drainage facilities in the northern portion of the property. The southern portion is developed with existing deienilon and waits yuaiiiy icll liilJCJ aiui iy ii iC Cdbt di Iu bUU1I i Ni upciiy iii It;. T' is southern edge of the property lies within the 100 year floodplain of Clear Creek. An existing irrigation ditch runs from the west property line east, then directly south on the west side of the office building. Portions are in a lined channel while other portions are piped. Please provide the overall area of the project. C. PROPOSED PROJECT DESCRIPTION Proposed development of the site consists of renovation and expansion of the existing office building. The proposed footprint is 23,000 sf. Proposed use is a veterinary medical building. The balance of the site will be used for parking, landscape areas, and detention and water quality facilities. Overall site imperviousness is approximately 76.5%. D. FLOOD HAZARD AND DRAINAGE STUDIES RELEVANT TO SITE The site was previously studied in a report entitled "Final Drainage Report for Lot 1, Onyx Park Subdivision" prepared by MNA Inc. and approved by the City of Wheat Ridge on January 27, 2000. FINAL DRAINAGE REPORT WHEAT RIDGE ANIMAL HOSPITAL WHEAT RIDGE, COLORADO It needs to be clarified that this drainage information is for Lots I & 2, Onyx Park Sub only 3. HISTORIC DRAINAGE SYSTEM and does not include any drainage info for the northerly portion of the project, being Lot I of A. MAJOR BASIN Kelly Sub Filing No. I. Furthermore, the drainage from the northerly portion needs to be analyzed The site lies within the Clear approximately 300 feet south of and the historic info provided in this section of the the vicinity of the Wheat Ridg narrative. with mixed uses of commercial and residential developme ts. Topography slopes mildly to the southeast towards Clear Creek. B. SUB -BASIN AND SITE DRAINAGE Current runoff rates for the site are identified in MNA report. Basins D1, D2, OS -2, and OS -3 represent a large portion of a site. Combined 5 year runoff from these basins is 4.7 cfs. 100 year runoff from the aforementioned basins is 10.9 cfs. Basin OS -1 quantifies offsite runoff tributary to the site from the northwest. 5year runoff from OS -1 is 3.5 cfs while 100 year flows are 7.1 cfs. Area of basin OS -1 is 1.1 acres. Detention and water quality is provided for basin D1, and water quality only is provided for basin D2. Discharge from basin D1 is along the east property line while discharge from basin D2 is to storm sewer running south to Clear Creek. In the present condition, basin D1 provides water quality and detention for 0.9 acres. Basin D2 provides water quality for 0.5 acres. 4. PROPOSED (DEVELOPED) DRAINAGE SYSTEM A. CRITERIA Drainage design criteria uses the Wheat Ridge Storm Drainage Criteria and the Urban Drainage and Flood Control District Criteria. Runoff quantities are estimated using the Rational Method for the 5 year and 100 year storm frequencies. B. RUNOFF For the purpose of analysis, the site is divided into multiple sub -basins. Sub - basin characteristics are described as follows: Basin A is a 0.82 acre basin on the west side of the building. The basin consists of paved parking area and landscape. Runoff from this basin flows south to a new sand filter basin providing water quality treatment. In minor rainfall events, storm water will overtop the water quality basin and be collected in existing inlets on West 43rd Avenue. During major events, water will overflow in a similar manor FINAL DRAINAGE REPORT WHEAT RIDGE ANIMAL HOSPITAL WHEAT RIDGE, COLORADO into West 43rd Avenue and flow overland south into Clear Creek. 5 year runoff is 2.38 cfs. 100 year runoff is 5.45 cfs. Basin B1 is a 0.53 acre basin located northwest of the building main entry. The basin consists of paved parking area and landscape. Runoff from this basin is collected in an inlet and piped to a new EURV detention facility located at the northeast corner of the site. Overflow and discharge from this basin is to West 44t11 Avenue. 5 year runoff is 1.62 cfs. 100 year runoff is 3.78 cfs. Basin B2 is a 0.54 acre basin located on the northerly half of the site. The basin consists of paved parking area and landscape. Runoff from this basin is collected at the northeast corner of the site and delivered via curb chase to a new EURV detention facility located at the northeast corner of the site. Overflow and discharge from this basin is to West 44' Avenue. 5 year runoff is 1.57 cfs. 100 year runoff is 3.74 cfs. Basin C is a 0.54 acre basin located on the east side of the building. The basin consists of paved parking area and landscape. Additionally the basin includes an area designated for building addition. This area is treated as impervious coverage for calculation purpose although it will be landscaped in the interim condition. Runoff from this basin flows east to an existing detention and water quality facility located in a landscape island. Controlled outflow from this basin flows east onto adjacent property in the same manner as presently exists. Basin C corresponds to original Basin D1 in the MNA report. The MNA basin should not be confused with the new basin D1 defined in this report. MNA basin D1 was calculated as 0.9 acres. The detention and water quality basin associated with this basin was designed to accommodate the 0.9 acre basin. The comparative cize of hni¢in (7, of n r;4 acrP.q indicates a reduction in developed flow and reauired detention volume. As the detention facility will remain in its current configuration, excess volume should now be available. Prior 5 year runoff for MNA basin D1 was 2.3 cfs. 100 year runoff was 4.7 cfs. New run off for basin C is 1.67 cfs for the 5 year storm and 3.85 cfs for the 100 year storm. Basin D1 is a 0.53 acre basin which captures runoff from the roof of the structure. Runoff from this basin is to be piped to the south to an existing water quality basin along West 43rd Avenue. In the present condition, the roof was to drain to said water quality basin. However, it appears that the existing roof drain pipe was connected to the inlet in the existing water quality basin effectively bypassing water quality treatment. The new roof drain collection pipe system will surface discharge in the existing water quality facility to take full effect of the available water quality treatment. The water quality basin was designed to treat an area of 0.50 acres. Proposed tributary area is comparable at 0.53 acres. Minor storm events will be captured and piped to Clear Creek. During major events, water will overflow into West 43rd Avenue and flow overland south into Clear Creek. 5 year runoff is 1.93 cfs. 100 year runoff is 4.08 cfs. Discuss how the percolation tests were performed, e.g., number of tests holes, depth of the holes, depth of the local water table, etc. Also include all test data in the Appendix. Need to include a statement that a minimum of one (1) foot of freeboard has been provided in the design, and include the WSEL100 and top of wall elevations to support the statement.

Recorded percolation rate was found to be 3 inches per hour. A safety factor of 20% was applied and a design rate of 2.5 inches per minute is used for design. Required flat surface area to achieve a 72 hour drain time is calculated at 260 sf.

Pi s are designed to carry the 100 year flow without surcharge. What is the anticipated drain time for the 100 -year? Please note the following: If the percolation test data is sufficient and water table is deep, maybe the proposed infiltration basin can handle the volume for the 100 -year event. If this is the case you do not need to include the EURV; just use the 100 -year volume for the basin. The City will then review this design as if it were an underground facility (using those criteria), and the release rate will be the bottom area of the pond multiplied by the average percolation rate. This is the primary reason we require a minimum of 2, and preferably 3, perc tests completed (to obtain the average rate) within the area of the pond. Refer to the info under Average Percolation Rate and the associated Notes on page 5 of the Site Drainage Requirements. 4. 5 This section needs to be renumbered to Section 5 (Section 4 is the Proposed (Developed) Drainage System FINAL DRAINAGE REPORT WHEAT RIDGE ANIMAL HOSPITAL WHEAT RIDGE, COLORADO CONCLUSIONS A. DISCUSS IMPACT OF IMPROVEMENT The developed Wheat Ridge Animal Hospital project will improve drainage conditions at the site. The new sand filter basin at basin A will improve water quality over that which presently exists. Runoff to the existing detention and water quality facility located on the east side of the site will be reduced lessening flows to the adjacent private property. Increased runoff from the northerly portion of the site will be mitigated with a new EURV FVII Spectrum detention facility. B. STATE COMPLIANCE WITH APPLICABLE Proposed improvements are in conformance Drainage critera.

The Conclusion should include a comparison of the historical runoff rates from the site (including from the northerly area) versus the developed release from the site. If the new basin on the north end is able to handle the 100 -year volume, the runoff from the northerly portion of the site will be reduced to near zero. This information should be conveyed to the reader as hard evidence that this design will greatly enhance the drainage conditions.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (hftp://www.nres.usda.govtwps/portal/ nres/main/soils/healthn and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (http:// offices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil Scientist (hftp://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nres142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. E] Custom Soil Resource Report An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha - Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.

A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each property or quality. Soil Qualities and Features Soil qualities are behavior and performance attributes that are not directly measured, but are inferred from observations of dynamic conditions and from soil properties. Example soil qualities include natural drainage, and frost action. Soil features are attributes that are not directly part of the soil. Example soil features include slope and depth to restrictive layer. These features can greatly impact the use and management of the soil. Hydrologic Soil Group Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long - duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. 12 Custom Soil Resource Report Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas.

As shown on Figure 1, the site is located west of Kipling Street and south of W. 44"' Avenue. A 36,955 square foot animal hospital is proposed on three individual lots. One lot is an existing 21,700 square -foot office building and the other two lots include about 1.837 acres of light industrial use. Figure 2 shows the conceptual site plan. Table 1 shows the trip generation potential for both the previous and the proposed land use on the site based on both the formula and average rates from Trip Generation, 9"' Edition, 2012 by the Institute of Transportation Engineers (ITE). Using formula rates, the proposed development is projected to generate about 1,408 additional vehicle -trips on the average weekday, about 81 additional vehicle -trips during the morning peak -hour, and about 59 additional vehicle -trips during the afternoon peak -hour. Using average rates, the proposed development is projected to generate about 1,638 additional vehicle -trips on the average weekday, about 104 additional vehicle -trips during the morning peak -hour, and about 129 additional vehicle -trips during the afternoon peak -hour. Figure 3 shows the estimated directional distribution of the generated traffic with about 40 percent oriented to/from the north via Kipling Street, about 30 percent oriented to/from the south via Kipling Street, about 15 percent oriented to/from the west via W. 44" Avenue, and about 15 percent oriented to/from the east via W. 44' Avenue.

Dated this Z1 day of201 Wheat Ridge Animal Hospital —Studio DH Architecture 10/21/15 10055 W. 43`d Ave. Wheat Ridge, CO Request and Description of Proposal: We are requesting approval of our proposal of this Amendment to the existing Onyx Park Specific Development Plan at the address referred to above in Wheat Ridge, Colorado. We are including a new adjacent lot from the Kelly subdivision, currently zoned C-1. We propose to demolish the existing structure on the 44th Ave. fronted property to allow for new parking lot and entrance drive and add on to the existing building as shown in the SDP package. We are also expanding to the adjacent lot already within the subdivision to create much needed parking for the new development. The Specific Development Plan Amendment is consistent with the existing Specific Development Plan. The Specific Development Plan Amendment is consistent with the design intent or purpose of the existing Outline Development Plan. The proposed uses indicated are consistent with the allowed uses in the Outline Development Plan. The site is appropriately designed and is consistent with the development guidelines established in the Outline Development Plan. The applicant will provide upgrades as necessary to fulfill any inadequate infrastructure to serve the proposed facility. The proposed Specific Development Plan Amendment is in substantial compliance with the applicable standards set forth in the Architectural and Site Design Manual, Streetscape Design Manual and other applicable design standards of the City of Wheat Ridge. Wheat Ridge Animal Hospital has outgrown its current location and has no real possibilities to expand at the existing location. Therefore, they have purchased the former ME Engineers' office building and an adjacent lot to the north to expand their facility and better serve the community with emergency and after-hours animal care, to become an even better regional state -of -the art animal hospital. The existing building they are relocating to is a two-story office building located a half block west of Kipling on 43`d Ave. of 21,700 SF, much of which is a second story above parking on the ground level. We are proposing to fill in approximately two of the three bays of this parking area on the ground level (with much of the third bay becoming covered yet open dog exercise area) and add one and two story additions on the west and east sides of this north -south running building for a total building of approximately 35,000 SF. There will also be an MRI unit that is a separate modular unit on the back side of the building for ease of future replacement. A future small one story addition to house a Linear Accelerator and support is planned as well. A new main entrance from 44th Ave. is planned, with access from 43`d, and additional parking and landscaping is proposed for the undeveloped western lot and the new adjacent lot to the north (currently a landscaping business with small building that will be demolished). There will be emergency, routine, rehabilitation and specialized veterinary healthcare services provided here. With this relocation and expansion, the Wheat Ridge Animal Hospital will be one of the top animal hospitals in the country, a regional center for quality animal care. fProperty Information GENERAL INFORMATION Schedule: 419633 Parcel ID: 39-211-11-036 Status: Active Property Type: Commercial Property Address: 10163 W 43RD AVE WHEAT RIDGE CO 80033 Mailing Address: 03695 KIPLING ST WHEAT RIDGE CO 80033 Neighborhood: 232 - PROPERTY DESCRIPTION Subdivision Name: 568330 - ONYX PARK SUB Print Help OwnerName(s) VORTEX REAL ESTATE INVESTMENTS LLC Block Lot Key ISection Township Range Quarte Section Land Sgft 0001 21 3 69 NE 60634 Total 60634 Assessor Parcel Maps Associated with Schedule pmap39-211.pdf COMMERCIAL INVENTORY Building Number Year Built Quality IFlooriStructure Type 1 12001 Average 2 Office/Net Rent SALE HISTORY Graphic Parcel Map MapQuest Location UnitsiMain SgFtIBasement SgFtjLand A 1 118643 10 160634 Sale Date Sale Amount Deed Type Reception 04-24-1995 0 Plat F0044228 10-15-1999 240,000 Warranty Deed F0964495 02-02-2000 0 Warranty Deed F1013442 08-31-2015 3,240,000 Special Warranty Deed 2015092831 SMA ll�r Vf�1�IM1aV1\ 2015 Payable 2016 20 2015 Mill Levy Information Actual Value Land 363,400 Imp 1,454,000 Total 1,817,400 WHEAT RIDGE Assessed Value Land 105,386 Imp 421,660 Total 527,046 2014 Payable 2015 TBA URBAN DRAINAGE&FLOOD C SO PLAT Actual Value Land 350,000 Imp 1,400,000 Total 1,750,000 Assessed Value Land 101,500 Imp 406,000 Total 507,500 Treasurer Information View Mill Levy Detail For Year 20 2015 Mill Levy Information Tax District 3109 County TBA School TBA WHEAT RIDGE TBA ARVADA FIRE DIST TBA FRUITDALE SAN DIST TBA REGIONAL TRANSPORTATION DIST TBA URBAN DRAINAGE&FLOOD CONT DIST TBA URBAN DRAINAGE&FLOOD C SO PLAT TBA VALLEY WATER DIST TBA Total TBA 1 Property Information History GENERAL INFORMATION Schedule: 419634 Parcel ID: 39-211-11-037 Status: Active Property Type: Vacant Land Property Address: 10173 W 43RD AVE WHEAT RIDGE CO 80033 Mailing Address: 3695 KIPLING ST WHEAT RIDGE CO 80033 Neighborhood: 202 - PROPERTY DESCRIPTION Subdivision Name: 568330 - ONYX PARK SUB Print Help Owner Names) VORTEX REAL ESTATE INVESTMENTS LLC Block Lot Key Section Township Range QuarterSection Land Sqft 0002 21 3 69 NE 153760 Total 153760 Assessor Parcel Maps Associated with Schedule pmap39-211.1)df Graphic Parcel Map MapQuest Location SALE HISTORY Sale Date Sale Amount Deed Type iReception 04-24-1995 0 Plat F0044228 09-24-2008 425,000 Special Warranty Deed 2008090073 08-31-2015 3,240,000 Special Warranty Deed 2015092831 2015 Payable 2016 015 2014 2015 Mill Levy Information Actual Value Land 349,400 Total 349,400 School Assessed Value Land 101,326 Total 101,326 2014 Payable 2015 TBA REGIONAL TRANSPORTATION DIST Actual Value Land 241,900 Total 241,900 VALLEY WATER DIST Assessed Value Land 70,151 Total 70,151 Treasurer Information View Mill Levy Detail For Year2� 015 2014 2015 Mill Levy Information Tax District 3109 County TBA School TBA WHEAT RIDGE TBA ARVADA FIRE DIST TBA FRUITDALE SAN DIST TBA REGIONAL TRANSPORTATION DIST TBA URBAN DRAINAGE&FLOOD CONT DIST TBA URBAN DRAINAGE&FLOOD C SO PLAT TgA VALLEY WATER DIST TBA Total TBA PropertyHistory J Information ji Adh.;&= I GENERAL INFORMATION Schedule: 419633 Parcel ID: 39-211-11-036 Status: Active Property Type: Commercial Property Address: 10163 W 43RD AVE WHEAT RIDGE CO 80033 Mailing Address: 03695 KIPLING ST WHEAT RIDGE CO 80033 Neighborhood: 232 - PROPERTY DESCRIPTION Subdivision Name: 568330 - ONYX PARK SUB Print Help Owner Name(s) VORTEX REAL ESTATE INVESTMENTS LLC Block Lot Key Section Township lRange lQuarterSection Land Sqft 0001 21 3 69 INE 60634 Total 60634 Assessor Parcel Maps Associated with Schedule pmap39-211.pdf Graphic Parcel Map MapQuest Location COMMERCIAL INVENTORY Building Number Year Built Quality IFlooriStructure Type jUnitsjMain SgFt Basement SgFt Land Area 1 12001 jAverageJ2 Office/Net Rentablell 118643 10 60634 SALE HISTORY Sale Date Sale Amount Deed Type Reception 04-24-1995 0 Plat F0044228 10-15-1999 240,000 Warranty Deed F0964495 02-02-2000 0 Warranty Deed F1013442 08-31-2015 3,240,000 Special Warranty Deed 2015092831 .ISA .- VISI -4N 1 AWIM 2015 Payable 2016 20 I Tax District Actual Value Land 363,400 Imp 1,454,000 Total 1,817,400 ARVADA FIRE DIST Assessed Value Land 105,386 Imp 421,660 Total 527,046 2014 Payable 2015 TBA VALLEY WATER DIST Actual Value Land 350,000 Imp 1,400,000 Total 1,750,000 Assessed Value Land 101,500 Imp 406,000 Total 507,500 View Mill Levy Detail For Year 2015 Mill Levy Information 20 I Tax District 3109 County TBA School TBA WHEAT RIDGE TBA ARVADA FIRE DIST TBA FRUITDALE SAN DIST TBA REGIONAL TRANSPORTATION DIST TBA URBAN DRAINAGE&FLOOD CONT DIST TBA URBAN DRAINAGE&FLOOD C SO PLAT TBA VALLEY WATER DIST TBA Total TBA 15 2014 'ol .

Plan: Neighborhoods Existing Site Conditions/History: The property is located at 10163-10173 W. 43'd Avenue, between 44`h Avenue and 43`d Avenue, west of Kipling Street. The property is currently zoned Planned Commercial Development (PCD), as is the property to the west. The remaining adjacent property, on three sides, is zoned C-1 (Commercial -One). The immediate surrounding area is either currently developed in commercial and office uses, or is vacant and planned for commercial use. The property was platted as Lot 1 and Lot 2 of the Onyx Park Subdivision in 1995. An Outline Development Plan (ODP) for the property was also approved in 1995. Lot 1 currently has on it a two-story office building that is roughly 22,185 square feet in size. The second story of the structure cantilevers over surface parking for the structure. Lot 2 is currently serves as an unpaved parking lot and outside storage. In total, Lot I and Lot 2 comprise 114,394 square feet of land or 2.64 acres. Lot 1 and Lot 2 have 390'of frontage along W. 43rd Avenue. Lot 2 has an appendage that extends north to W. 44`h Avenue, which provides thirty-five feet (35') of frontage along W. 44`h Avenue. Currently the only access for Lot 1 is off W. 43rd Avenue and the only access for Lot 2 is off of W. 44`h Avenue. The access off W. 44`h Avenue is shared with the A Tip Top Tree Company at 10140 W. 40 Avenue through a shared access easement that runs the entire 35' access frontage along W. 44`h Avenue. Lot 2 is also subject to a 15' foot irrigation easement that serves the Oulette Irrigation Ditch. Applicant/Owner Preliminary Proposal: The applicant is proposing to relocate the Wheat Ridge Animal Hospital to the subject site. The applicant intends to occupy the entire building on Lot I and add an additional 9,015 square feet to the building. This addition will take place under the cantilevered portion of the building's second story. The building will have two entrances which will separate the two primary functions of the business. The emergency care entrance will be at the north end of the structure and regular veterinarian patients will enter at the south end. Currently there is no paved connection between Lot 1 and Lot 2. The applicant is proposing to connect Lot 1 and Lot 2 via two drives, a one-way drive to the north of the building and a two- way drive to the south of the building. Lot 2 will be solely used as client and staff parking, in total 105 new parking stalls will be added to the site. The applicant has proposed to add an additional access along W. 43rd Avenue along the western property line. Between the two access drives along W. 43rd Avenue the applicant is proposing to extend the existing site detention. Will a neighborhood meeting need to be held prior to application submittal? No, a neighborhood meeting is not required for a Specific Development Plan and consolidation plat application. Planning comments: The following items were discussed based on the applicant's proposal: Zoning The site was rezoned to Planned Commercial Development (PCD) in 1995. The PCD zone district is site specific and defines specific development standards that apply to the site. Allowable land uses on Lot 1 are all included in the Commercial -One (C-1) district. The proposed use of the lot for an Animal Veterinary Hospital and Clinics is consistent with the permitted principal uses in the C -I district; so long as no outdoor runs or pens are incorporated in the design. 2 Parking/Surfacing By City Code, all non-residential properties that are subject to wheeled traffic for access, parking, sales or storage, shall be properly graded for drainage and shall be surfaced with concrete, asphalt or brick pavers. Improvements to Lot 2 will need to be designed to accommodate drainage landscaping and pedestrian connections. City staff is requesting that when the appendage for Lot 2 is paved north to 44`h Avenue, an attached sidewalk be provided to accommodate pedestrian traffic north to 44`h Avenue. Signage The applicant didn't provide any signage for review. The City allows freestanding signs based on the total footprint of the building. Freestanding signs must be appurtenant to public streets and cannot be located off -premise. The applicant proposes a 22,815 sq. ft. building footprint which will allow up to 135 square feet of freestanding sign area. Freestanding signs are allowed with a maximum height of fifteen feet (15'). The applicant is limited by code to 1 wall sign per street frontage but can utilize window or door signs so long as the signs do not obstruct more than 25% of the door or window area. Wall signage permitted is allowed as 1 square foot of signage for every linear foot of the side of the building, to which it is affixed. For more information on signage, please refer to Section 26-710 of the City Municipal Code. Landscaping Pursuant to the ODP document, a minimum of 10% landscaped coverage is required on the combined lots. A 10' wide landscaped buffer strip with street trees will be required along the frontage of Lot 2. Additional trees and shrubs will be required on the undeveloped lot as well. For more information on landscape requirements, please refer to Section 26-502 of the City Municipal Code. Public Works comments: The following items were discussed based on the applicant's proposal: Drainage Site drainage requirements are based on the area of disturbance created by new development. The more impervious surface (such as paved parking and buildings) that is added to the site, the greater the drainage requirements will be. In either scenario, drainage documents shall be signed and sealed by a Professional Engineer licensed in the State of Colorado. The proposal falls into the Major Re -Development category under the City of Wheat Ridge Site Drainage Requirements. Major Re -Developments typically require full flood attenuation with Water Quality (WQ) improvements. However, due to the availability of an outfall directly to Clear Creek, only WQ will need to be addressed. No flood attenuation will be retired if the proposed WQ facility is directly connected to the existing storm sewer in W. 43 Avenue. A Drainage Report shall be required with calculations for 100% Water Quality Capture Volume (WQCV) for the entire site. 3 The Drainage Plan shall indicate the proposed grading, existing and proposed drainage patterns, and the location of the water quality facility. When the Report & Plan are in an approvable condition, a hardcopy of both the Drainage Letter and Plan, signed and sealed by a CO licensed Professional Engineer shall be provided. A PDF scan of the signed/stamped documents shall accompany the hardcopies for Public Works approval. If the area of the disturbance will meet or exceed one (1) acre, then a Stormwater Management Plan (SWMP) associated with the required CDPS Permit shall be submitted to the City of Wheat An existing ditch crossing the property must be accommodated. The City's most recent contact for the Oulette Ditch Company is Dale Pierce who can be reached 303-549-2265. Building Division comments: A representative of the building division was not present. The City has adopted and currently enforces the 2012 Edition of the International Codes and the 2014 Edition of the National Electrical Code and enforces the 2009 -Al 17.1 ANSI Standard for Accessible and Usable Buildings in determining requirements related to building accessibility. Designs should conform to the requirements of these codes. Please refer to the Building Division's permit submittal checklist for additional information: http://www.ci.wheatridge.co.us/1068/Permit-Submittal- Information. Questions related to the requirements of the International Fire Code should be directed to the appropriate fire district in which the property is located. Specific Development Plan (SDP) Amendment/Lot Consolidation Process The first step in the process began with the pre -application meeting on May 7, 2015. After the pre -application meeting is held, a formal application may be submitted. The zone change and Outline Development (ODP) were approved in 1995. The most recent amendment to the Final Development Plan (FDP) was approved in 2006. Amendments to the planned development documents are required when an applicant wishes to develop or redevelop a property in a way that varies from the originally approved documents. Proposed changes that affect the character of a development, the underlying development standards, or the permitted land uses often require an amendment to the approved Outline Development Plan. A Specific Development Plan may vary from the approved ODP so long as the variations are within the parameters of the ODP. The proposed amendment to an approved SDP can be reviewed administratively if the modification is consistent with the original character of the development, uses and development standards. It is anticipated that this SDP modification can be approved administratively. Because the proposed development involves two lots from the Onyx Park subdivision, a lot - consolidation process will be required but will be an administrative review as well as the SDP process. In both cases, when the application is submitted, a staff planner will be assigned to handle the case. This person is the project manager for the case and will be the contact at the City throughout the entire entitlement process. F11 The case manager will review the submittal application for content. If all submittal requirements have been met, the proposal will be referred to outside service agencies (Xcel Energy, water district, fire district, etc.) and other City agencies (Public Works, Economic Development, etc.) for their review and comment, generally for a period of 15 days. After all comments have been received, the case manager will forward those to the applicant. Modifications to the SDP and plat documents may be required as a result of these comments. Once all comments have been addressed to the case manager's satisfaction, findings will be prepared by the case manager for the Community Development Director's review. Once approved a blackline photographic mylar will be submitted to the Community Development Department with appropriate recording fees for recording with the Jefferson County Clerk and Recorder's Office. A building permit will be required to be reviewed and approved prior to any site construction. Utility Providers The City of Wheat Ridge is not a full-service city. The utility and service providers for this property include: • Valley Water, phone: 303-424-2844 • Clear Creek Valley Sanitation: 303-424-4194 Fruitdale Sanitation: 303-424-7252 • Arvada Fire District #1: 303-424-3012 All land use applications will be sent on referral to these agencies for comment; however staff encourages potential applicants to contact service districts ahead of time. This may help to understand any design or infrastructure requirements and potential costs associated with the proposed project. Please be aware that the above comments are for general information purposes only. Staff cannot predict the outcome of any land use development application. A favorable response from staff does not obligate any decision-making body (Community Development Director, Public Works Director, Planning Commission and/or City Council) to a desired outcome. Staff will provide the best advice available given existing regulations, current policy, political climate and information submitted.
