Home My WebLink AboutPBG-11-01F4 FROM: Lauren Mikulak \111 DATE: July 2, 2012 Case No. PBG- I 1 -0 1 is being closed due to inactivity. After review of the first submittal, the applicant met with staff on October 6, 2011 to discuss alternate site designs. A second submittal was never received. The applicant was notified via letter that the case would be closed due to inactivity, and no communication was received. This memo shall serve as closure to Case No. PBG-1 1-01. City cat Wheat Ridge Municipal Building 7500 W. 29 Ave. Wheat Ridge. CO 80033-8001 P. 303.235,2846 F: 303.235.2857 June 8, 2012 Mr. Alex Brewer 13620 W. 30"' Place Golden, CO 80401 It To date, the land use application Case No. PSG- 1.1 -01 has been inactive for a period of eight months. Typically, after a stagnant period of 90 days a land use application is withdrawn, and the process is abandoned. Please note that if no communication is received by June 29, 2012 1 will assume that you are no longer pursuing your application and it will be considered withdrawn. Please feel free to be in touch with any questions or concerns. I can be reached by phone at (303) 235-2845 or by email at lmikulak@ci.wbeatridge.co.us. www.d.wheatridge.co.us Mike Rudd (Rudd & Associates Architects) Specific Site Location: 12275 W. 1-70 Frontage Road North Existing Zoning: Light Industrial (1) Existing Comp. Plan: Mixed Use Employment / T.O.D. Site Applicant/Owner Preliminary Proposal: The applicant, Alex Brewer, is proposing an amended site plan that includes an expansion of the existing building. A proposal was first discussed at a pre-application meeting on June 2. At that time, the proposed site plan included two primary structures an expanded office/warehouse building, and Will a neighborhood meeting need to be held prior to application submittal? No, a neighborhood meeting will not be required as part of the proposed development. Planning comments: The discussion focused primarily on the new site plan with a single primary structure and the problem solving related to utilities and drainage. Most requirements—those related to zoning, landscape, setbacks, fences, and access -- remain the same as were discussed at the first pre-application meeting. The following items supplement the June 2" discussion and relate to the amended site plan. Parking Most of the property is currently covered in loose gravel. As discussed in the June pre-application meeting, all areas that will be subject to wheeled traffic (for access or parking) must be surfaced with concrete, asphalt or pavers and striped to designate parking stalls. The amount of required off-street parking is based on land use. For an office/warehouse use, the off- street parking requirement is I space per 600 square feet of warehouse plus I space per 300 square feet of office. The site is large enough to meet the parking requirements. Most parking may be accommodated along the eastern property line. The parking stalls along the southern property line may be moved to allow a larger landscape/detention area. Building Division comments: The building code requires public utility connections for any addition increasing the floor area by 50% or more. The proposed addition increases the building by over 200%. This means that even though a single building is now proposed for the site, the applicant is still required to connect to public infrastructure for water and sewer. This requirement may be appealed to the Building Code Advisory Board. The Chief Building Official, will provide a written determination regarding the utility requirements. An applicant then provides a written narrative and appeal request. A meeting with the Building Code Advisory Board is scheduled on an as-needed basis. Please contact Chief Building Official John Schumacher with any further questions. The applicant may use a combination of facility types including porous landscaping, porous pavers. or other innovative designs. For questions related to site drainage requirements, please contact Dave Bros man, Development Review Engineer, Access As was the stated in the previous pre-application meeting, City Code requires that curb cuts be no closer than 25 feet from a property line. If the existing curb cut is moved or improved, a right-of-way construction pert may be required and a contractor must have a Municipal Contractor License. The permit and license are both available through the City's Public Works Department. Process—Building Permit The applicant's amended request requires only a building permit. In addition to construction documents, the building permit application will need to include a site plan, landscape plan, building elevations, and the necessary civil documents required by Public Works. A photometric plan is also required if outdoor lighting is proposed. The fire district will also review the building permit and site plan. They should be consulted during the design phase, especially in regard to emergency access. Phone Numbers 9 September 21, 2010 CIVIL ENGINEERING M= 1.

CQLOIVl Prepared for: Alex Brewer 13620 W 30' PI Golden, CO 80401 Prepared by: Henry Hollender, P.E. HVS Engineering, Inc. 9201 W. 58 Ave. Lakewood, CO, 80226 September 2, 2011 ' t1 " If" A. Site Location The Brewer Development is located on the north side of West 48 Avenue, which is also known as the 1-70 frontage road, approximately 500 feet east of Ward Road at 12275 West 48 Avenue in Wheat Ridge, Jefferson County, Colorado, (See Vicinity Map in the Appendix.) The property is bordered on the north by industrial development and to the east and west by commercial property. Open space is located across West 48th Avenue south of the property. B. Site Description The lot is 0.92 acre in size. Currently, there is one existing 3,000 SF commercial building on the lot. Much of the southern portion of the site is paved with approximately 6,100 SF of asphalt and most of the rest of the site is gravel surfaced. There are existing concrete pads totaling about 675 SF on the north and south side of the existing building. The lot generally drains from north to south on a 2% grade, sheet flowing over existing sidewalk into the gutter on the north side of West 48 Avenue. This gutter drains into a curb inlet, located in a sump near the southwest comer of the building. This inlet drains into an existing 18" pipe that drains to a manhole into a 48" pipe that is part of an existing storm drainage/irrigation system under the control of Juchem Ditch. Very little stormwater drains off or onto the site from adjacent properties to the north, east or west. C. Proposed Project Description A 3,800 SF addition to the front and east side existing building and a new 6,000 SF building behind the existing building are proposed. The existing lot around the buildings will be graded and just under 20,000 SF of new asphalt pavement and approximately 8,100 of landscaped area will be placed. D. Flood Hazard and Drainage Studies Relevant to Site The site is not located in any local or federally designated flood hazard area. H. HYDROLOGY A. Major Basin The site is located in the Clear Creek Basin, although drainage to Clear Creek is cut off by several irrigation ditches and ponds. The major basin is urban development with mixed uses and topography. B. Sub-Basin and Site Drainage There are two basins on the site considered on this project. Basin A consists of the northwestern 0.53 acres of the site that drains to a grass swale that will be constructed to drain that portion of the site. Basin B consists of 0.38 acres that drains to a water quality pond that will be constructed in the front of the site. 0.1 acres in the fringes of the site sheet flow off -site. A third basin, consisting of the area that drains to the 18" pipe drained by the inlet near the southwest comer of the site identified as Design Point I (DP -1), is also considered in this report. This basin is analyzed to make sure that the downstream drainage system will not be adversely impacted by the proposed construction. The rational method is used to detemline flows from the minor (5-year) and major (I00 -year) storms in Basins A and B, the entire site (both the historical and proposed) and to DP-1. The 2-year flow is also calculated for Basin A to use in the design of the grass swale. Urban Drainage spreadsheets are used to compute these flows. These spreadsheets require the area, percent imperviousness, MRCS Hydrologic Soil Group, storm return period, one-hour precipitation for that period, and flow path information necessary to compute time of concentration for each Basin. The drainage areas for Basins A and B and the entire site are delineated on the Drainage Plan, which is Sheet I of 3 in the rear pocket of this report. The drainage area for DP -1 is delineated on Sheet 3 of 3 in the rear pocket of this report. The property located immediately to the west of the site is not included in the drainage area for DP -1, because a detention pond was constructed on that site. Instead, 5-year and 100-year flows from that site were obtained from the Final Drainage Report for E.O.C. prepared on May 15, 1998 by Jehn and Associates, Inc. for Ojala & Company and added to the flows calculated for the rest of the basin draining to DP -1. For Basins A and B and entire site calculations, the percent imperviousness used in the spreadsheets is based on actual values of the proposed development (or, for the historical flows, existing condition) using Urban Drainage and Flood Control District (UDFCD) recommended values of 100% imperviousness for pavement 90% imperviousness for roofs, and 40% imperviousness for gravel. For DP -1, the UDFCD recommended value of 80% imperviousness for light industrial development is used. This percent imperviousness is more than either the existing or proposed condition on the Brewer site and is assumed to be a conservative value for the entire basin. Soils on the site are identified in the Web Soil Survey for the Golden Area as Dacono variant gravelly clay loam, 0 to 3 percent slopes, which is in Hydrologic Soil Group C. One-hour precipitation values of V for the 2-year storm, 1.4" for the 5-year storm, and 2.7" for the 100-year storm were used. Flowpath information was obtained using topographic information on Sheet I of 3 for Basins A, B, and the overall site and on Sheet 3 of 3 for DP -1. Information for Reach 3 included in the flowpath calculations for the proposed condition of the entire site was estimated to approximate the drain time of the water quality pond calculated in Section III below. The calculated flows are as follows: BASIN 2-YEAR 5-YEAR 100-YEAR A 0.61 cfs 1.02 cfs 2.94 cfs B - 1.01 cfs 2.39 cfs Overall Site (Historical) - 1.68 cfs 4.82 cfs Overall Site (Proposed) - 1.03 cfs 2.63 cfs DP-I (Calculated) - 9.37 cfs 21.47 cfs From E.O.C. Pond - 0.1 cfs 0.6 cfs Total DP- I - 9.47 cfs 22.07 cfs The UDFCD "Calculation of Peak Runoff Using Rational Method" spreadsheets are included in the Appendix. A. Criteria Basin A is designed drain into a 300' long, 1% sloped Grass Swale that will be constructed in the northern and western portion of the site. Basin B is designed drain into a water quality pond that will be constructed in the southern portion of the site. Since the proposed flows from the site are less than the historical flows, detention of the site should not be required if it can be shown that the downstream system can handle the anticipated flows. B. Capacity of Downstream System The downstream system is controlled by an existing 18" pipe that drains from the inlet near the southwest comer of the site to the manhole junction with the 48" pipe that carries the flow from Juchem Ditch. The capacity of the existing 18" pipe that is the outlet of DP -1 was checked using the UDFCD Spreadsheet " Culvert Stage- Discharge Sizing" included in the Appendix. This spreadsheet indicates that the design storm (5-year) will result in a water surface elevation of 5460.32 at the inlet. Since the top of the inlet is at elevation 5463.2, the pipe should handle the anticipated design flow. The 100-year flow (22.07 cfs) exceeds the flow that will result in the water surface elevation of the top of inlet (16.63 cfs). The spreadsheet indicates that, at a flow volumes exceeding 17.42 cfs, the water surface elevation will overtop the curb elevation of 5463.7 and flow into the open space to the south. This is an existing situation that actually will be improved slightly by the reduced 100 -year flow from the site in the developed condition. C. Grass Swale Design A Grass Swale is proposed in the north and west portion of the site to provide the required water quality controls for Basin A. The Grass Swale is designed using the UDFCD spreadsheet "Design Procedure Form: Grass Swale (GS)" included in the 10� Appendix. The spreadsheet indicates that a Grass Swale with a I% longitudinal slope and 4: side slopes will flow at a velocity of 0.79 ft/sec and a depth of 0.44 ft. The spreadsheet further indicates that a grade control structure is not required, but recommends that an underdrain be used. A detail of the proposed Grass Swale is included on Sheet I of 3 of the Drainage Plans. D. Water Quality Pond As stated previously, it is proposed that detention not be provided for the site since the proposed flows are less than historical flows. The lower proposed flows are dependent on the increased time of concentration resulting from the limited detention provided in a water quality pond that is proposed to be constructed in the southern portion of the site. This pond is also required to provide water controls for Basin B. The Water Quality Pond is designed using the UDFCD Spreadsheet "Design Procedure Form: Extended Basin Design (EBD) included in the Appendix. The spreadsheet indicates that a design volume (1. WQCV) of 0.011 acre-feet, or 479 cubic feet, is required. The Water Quality Pond shown on the drainage plan has a bottom elevation of 5463 and a top elevation of 5465. The Pond Volume calculation also provided in the Appendix indicates that a pond volume to elevation 5464 is 481 cubic feet. This provides the required volume plus 1 -foot of freeboard. Overflow from the pond is provided through the paved entrance above elevation 5464.48. The spreadsheet indicates that a forebay is not necessary in the pond. The spreadsheet does recommend that a micropool be constructed in the pond with a minimum depth of 2.5 feet. The micropool, however, is not provided due to concerns regarding the standing water that would result from construction of such micropool. The spreadsheet also provides design information for the outlet structure that is reflected in the outlet structure details provided on Sheet 2 of 3 of the Drainage Plans. The spreadsheet does indicate that use of the recommended minimum orifice diameter of 3/8" will result in a drain time of 21.9 hours, which is less than the recommended 40-hour drain time. The lower drain time should be acceptable due to the low flow volumes anticipated. IV. CONCLUSIONS The proposed Brewer Development will reduce the 5-year and 100-year flows leaving the site. Detention of the site is not required because these flows will be reduced and the downstream system will handle the design (5-year) flow. Furthermore, the downstream 100-year flow will not cause damage to any existing or proposed development. Water Quality controls for the site will be provided by a Grass Swale and a Water Quality Pond. M -1 ANNO . w ca a z CALCULATION OF A PEAK RUNOFF USING RATIONAL METHOD 11.

This is a request for approval of a planned building group to allow two primary structures on property at 12275 W. 1-70 Frontage Road North. The application was submitted on August 22, 201 At the time of application, it was acknowledged that a few submittal documents (namely, the preliminary drainage report and plan) were missing. While it is not typical protocol for staff to accept an incomplete application, we allowed you to file the application. After receiving a complete submittal, an application is sent on referral for a period of 15 days for review by outside agencies. Since the missing information is not expected to impact review by outside agencies, the referral period begins this week with a response deadline of September 8. After the review period ends, I will compile the responses and forward all comments to you. Please note that the Public Works Department cannot begin their 15 day review period until the drainage documents are received. In addition, if the drainage report results in significant changes to the site plan, a second referral period to outside agencies may be required. When the missing drainage documents are submitted, I will provide you with an updated timeline. After the referral periods are complete and all comments are addressed, the PBG can be approved. Once approved, the next steps will be to prepare a recordable document with the PBG plan and to submit the building permit application--these steps may occur simultaneously. A building permit may be issued once the approved PBG is recorded in the office of theJeft"erson County Clerk and Recorder. We are glad to be working with you on this project as it continues to move forward, If you would like to discuss this further, please feel free to contact me at 303-235-2845.

I The proposed building site is presently a vacant area • the North end • the property. The site is reasonably level with approximate slopes of 2.0% to the South/Southeast. The lot appears to be well drained with no erosion evident. I SUBSOIL CONDITIONS-.

We recommend the use of • continuous spread footing, due to the low expansion-consolidation potential of the analyzed soils. The foundation must be constructed at the location in which soils investigation was performed. Soil settlement resulting from the assumed structural loads is estimated to be one inch or less. Soil expansion at this site may be up to one inch in some areas. No foundation wall is to exceed twenty-five feet in length without utilizing buttresses or counterforts unless otherwise designed by the foundation engineer. Engineered steel reinforcements shall be required in the footings and foundation walls. This will give walls ♦ footing beams the strength to span • bridge over any loose • soft pockets • soil that may develop during construction. Owners shall be made aware of all contents of this report, and the fact that water accumulation around foundation elements is the primary cause • distressed foundations. Jobftl 1-2399 Detached Steel Building Page 4 of 9 To help prevent secondary damage that could be caused by slab movement, the following construction techniques are additional recommendations for the foundation construction. I SLAB ON GRADE CONSTRUCTION: I I When and where slabs-on-grade are chosen and the owners are willing to accept the risks associated with slab movement, the following recommendations are to be followed: • Slabs should be constructed as "free floating". Positive separations and/or isolation joints should be provided between slabs and all foundation walls, bearing members (columns), plumbing and utility lines. Isolation may be achieved with 1 /2 inch expansion material or by sleeving. Vertical movement • the slabs should not • restricted. b. Eliminate plumbing under slabs where feasible. Where such plumbing is unavoidable, it should be thoroughly pressure tested during construction. Job#] 1-2399 Detached Steel Building Page 5 of 9 5. If • forced air heating system is used and the furnace is located on the slab, we recommend provision of • collapsible connection between the furnace and the ductwork. In the event a hot water heating system is used, the piping should not be placed beneath the concrete slab. I BACK ILL AND SURFACE DRAINAGE: I The foundation and retaining walls must be well cured and well braced prior to backfilling.

Meredith Reckert, Senior Planner Lauren Mikulak, Planner I Dave Brossman, Development Review Engineer Specific Site Location: 12275 W. f-70 Frontage Road North (W. 48"' Avenue) Existing Zoning: Light Industrial (1) Existing Conip. Plan: Mixed Use Employment / T.O.D. Site Planning comments: The subject property does not currently conform to many of the City's development standards. In general, staff is pleased with the applicant's proposed upgrades and improvements that bring the site into conformity. The following iterns were discussed based on the applicant's proposed use and site design: Zoning The site is zoned Light Industrial (1) which provides for a variety of commercial and light industrial uses. The applicant's proposed office, warehouse, and storage uses are all allowed under the property's current zoning. No zone change is required. Parking Most of the property is currently covered in loose gravel. As part of development, all areas that will be subject to wheeled traffic (for access or parking) must be surfaced with concrete, asphalt or pavers and striped to designate parking stalls. N The amount of required off-street parking is based on land use. For an office/warehouse use, the off - street parking requirement is I space per 600 square feet of warehouse and I space per 300 square feet of office. Storage uses are not specifically listed in the schedule of required off-street parking, in which case the Director of Community Development will approve a parking plan based on similar uses. 1- A six (6) foot fence is permitted along the perimeter of the site, except within the front 50 feet of the property. A gate that restricts access the rear storage structure is permitted. In addition, the applicant may install barbed wire on top of a six-foot fence. Barbed wire is not counted toward the height of a fence. It may be up to two (2) feet in height and should point inwards towards the property. Process—Planned Building Group The applicant's request requires approval of a Planned Building Group (PBG) before any additional structures are constructed on the site. The first step in the process began with the pre-application meeting on June 2, 2011. The primary purpose of a PBG is to allow flexibility and diversification in the location of structures and the design of a lot by permitting more than one (1) primary structure on a parcel. The design of the site should promote better overall utilization of the site by promoting improved circulation and access, more efficient layout of parking, and a better overall landscape and architectural design for the site, After a complete 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 No= Building Division comments: The building division was not present at the meeting, but has expressed that the project will need to comply with the 2006 International Building Code. It does not appear that restrooms or sprinklers will be required in the rear storage building. Please contact Chief Building Official John Schumacher for questions related to the phasing of construction, building codes, perrnitting, or certificates of occupancy. Public Works comments: Drainage Site drainage requirements are based on the increase of impervious area on site—this includes the proposed additions, new structure, and bard surfaced parking areas. Because this area will exceed El 10,000 square feet, the applicant will need to meet all flood attenuation and water quality requirements for the entire site. Storm water detention is required for the whole site, but the applicant may use a combination of facility types including porous landscaping, , porous pavers, or other innovative designs. The site naturally drains to the southeast, but the slope is minimal and with minor grading the detention facilities could be moved to the southwest comer. An inlet is located in the right-of-way near the southwest comer of the site. An engineer will be able to determine the capacity of the inlet and prepare the required drainage report. Soils information and percolation test data for any proposed infiltration areas shall be included in the drainage report. For questions related to site drainage requirements, please refer to the information distributed at the meeting or contact Dave Brossman, Development Review Engineer. Access City Code requires that curb cuts be no closer than 25 feet from a property line. If the existing curb cut is moved or improved, a right-of-way construction permit may be required and a contractor must have a Municipal Contractor License. The permit and license are both available through the City's Public Works Department.
