HomeMy WebLinkAboutPEDERSEN AUTO PLAZA EXPANSION - MAJOR AMENDMENT - 26-97A - CORRESPONDENCE - (3)Comment # 8: Include the following detail in the utilityplan set: typical water/sewer services, meter pit, sand/oil interceptor, manhole adjustment and waterline bedding. The requested details have been shown per your request. Comment # 9: Maintain the required landscape/utility separation distances on the landscape plans. Done - Issue Contact: Roger Buffington Comment # 13: Any connections to the 18-inch sanitary sewer must be made at a manhole. All sewer connections are now shown to connect directly into the existing manhole onsite. ZONING - Issue Contact: Gary Lopez Comment #I. Will the parking be adequate? The body shop alone could have 46 vehicle spaces for customers/staff (not including display/storage of inventory). Recent violation of storing inventory off the site prompts this question. The site is utilized for maximum efficiency of parking for the intended use - we are not aware of any violations! Comment #2: Will trash/rubbish be stored within the building? No trash enclosures shown. Please refer to General Note #3. Comment #3: Detached building, will that be built now? No elevations shown. If built later, minor amendment required for footprint and elevations at that time. Please refer to General Note #6. I believe we have addressed all concerns known to us.

Pedxings on site should match pattern and color from first phase. Note has been added to site plan that crosswalks are to match existing NATURAL RESOURCES - Issue Contact: Doug Moore Comment # 12: Single Trash Hauler - We request that a single trash hauler be used for both Existing Business and the Proposed Business Expansion. The existing trash enclosure at the existing facility will serve the entire project, including the proposed future detached building. WATERIWASTEWATER - Issue Contact: Jeff Hill Comment # 4: Water and sewer services must remain perpendicular to the mains when possible. Where connecting to a main, all utility services are shown as perpendicular Comment # 5: Place curb stop and meter pit adjacent to the street. The curb stop and meter pit have been revised as requested. Comment # 6: Field locate, show and label all existing water/sewer mains, services and their associated appurtenances. Refer to the utility plan for further clarification of existing services, mains, etc. Comment # 7: Our records indicate that there are 2 existing cathodic protection test stations within thisproject vicinity. Show and label these on the plans and include a note to protect in place. Also include a note to coordinate any relocation or adjustment with the City utilities at 221-6700. The two cathodic protection test stations are now noted as requested.

Also, please provide documentation that the new 100 year water surface elevations will be within the current drainage easements. This can be done with an exhibit in the report showing the existing WSEL, new WSEL and current drainage easements. A telephone conversation with Wes Lamarque of the City of Fort Collins Stormwater Department on August 16, 2001 confirmed that the ponding being proposed with the Pedersen Auto Plaza Expansion lies within existing drainage easements and/or extents of ponding as dictated by construction drawings designed by Stewart & Associates, and approved by the City of Fort Collins. Furthermore, the addition of the horizontal orifice plates will be done in such as manner so that no temporary construction easements will be needed. He also verified that permission was not required from the off -site property owners due to the precedence of ponding already being approved for those properties. He did suggest that a letter be written to the affected property owners as a courtesy to remind them of the existing drainage easements and/or approved extents of ponding, and to inform of the activities that will take place with the Pedersen Auto Plaza Expansion. A copy of these letters will also be provided to the City, but neither written permission nor approval is required from the off -site property owners. An exhibit has been provided to easily show that the ponding being proposed with this project is consistent with what has already been approved and/or recorded. Comment # 27: Please look into the possibility of adding the WQCV to the quantity detention. Please see redline comment on page 4 of report. The release rate and storage volume of Detention Pond A have been modified slightly so that the pond provides the required detention storage volume on top of the required water quality capture volume. This has been done to accommodate the event where a 100-year storm closely follows a storm that has already filled the water quality capture volume. In order to achieve this, the 1-foot minimum freeboard requirement needs to be violated, and the City will need to grant a variance to this requirement. Comment # 28: Please see additional redline comments in the plans and report. See redline plans for additional responses to comments. (written in green) Page 8 of 10 LOCKWOOD ARCHITECTS, 217 Jefferson, Fort Collins, Colorado 80524. phone: 970.493.1023 fax: 970.493.6765 throughout the drainage report and construction drawings. In addition, the emergency overflow path for Detention Pond A is now labeled on the Drainage Plan. Comment #22: In Basin P-mod, the spillway is designed to carry the 100 year flow to the detention pond, while the storm sewer is designed to carry the 10 year flow. This is acceptable, however it is required to have the swale carry the 100 year flow times 1.33 for freeboard. The overtopping elevation is around 49.8 just northwest of the proposed building. Please show that the 100 year flow X 1.33 can pass without flooding the new proposed building, which has a F.F. elevation of 40.50. This should be just a matter of documentation in the report. The calculations for Weir Section B have been revised in the drainage report to show that the 100-year flow x 1.33 will safely pass without flooding the proposed finished floor. Comment # 23: Water Quality Outlet Structure: Please use City of Fort Collins standard outlet structure rather than drilling the orifice holes through the concrete. See USDCM, Vol. 3, Typical Structural BMP Details section, Figure 6-a. The structure has been designed in accordance with the Urban Storm Drainage Criteria Manual, Volume 3 — Best Management Practices updated in September of 1999. The proposed structure has been customized to be built into the walls of Detention Pond A. Details have been added to the construction drawings for the well -screen trash rack, which is consistent with what the City uses. The proposed water quality structure will operate like the one in Figure 6-a of the USDCM; however, it has been adjusted to be flush with the detention pond retaining walls. Comment # 25: Please consider tailwater affects for the existing storm sewer in Mason Street. There will definitely be some tailwater depth and even though there is no current documentation, a simple analysis can be done with the flow rates known for the ponds upstream draining into the pipe, and the flow to the retrofited inlet. An analysis was done at the modified inlet on the west side of Mason Street. This inlet has an existing 17.5" RCP coming out of it that conveys flow under Mason Street. The head required to convey the flows from proposed Storm Sewer Line C combined with the surface flows from Mason Street through the existing pipe was calculated. This elevation was then used as the starting point for the storm sewer modeling. As a result, the hydraulic grade lines of both Storm Sewer Line B and Line C have been raised. Page 7 of 10 LOCKWOOD ARCHITECTS, 217 Jefferson, Fort Collins, Colorado 80524. phone: 970,493.1023 fax: 970.493.6765 The proposed 7' high fence is now noted on the plans. Comment # 16: What does the detention pond handrail sit on? Are thereto be poured columns? The notes on the plans indicate that the retaining wall does not extend across this area and I assume it will not be bolted down to the dirt. Need more info here. The steel handrail will be secured to the top of the concrete retaining wall, via anchor bolts. See Grading Plan for clarification. Comment # 17: It appears that off -site drainage and construction easements will be needed with this project. A telephone conversation with Wes Lamarque of the City of Fort Collins Stormwater Department on August 16, 2001 confirmed that the ponding being proposed with the Pedersen Auto Plaza Expansion lies within existing drainage easements and/or extents of ponding as dictated by construction drawings designed by Stewart & Associates, and approved by the City of Fort Collins. Furthermore, the addition of the horizontal orifice plates will be done in such as manner so that no temporary construction easements will be needed. Comment # 18: Make changes to the ped ramp detail as shown. See revised details for changes to pedestrian ramp. Comment # 19: Provide detail 7-204 and 22-1. Details 7-20A and 22-1 are now included in the plan set. Comment # 20: See plans for additional comments. See redline plans for additional responses to comments. (written in green) STORMWATER UTILITY -Issue Contact: Wes Lamarque Comment # 21: Detention pond: The release rates for detention pond A differ between the report and plans. Please check calculations and revise. Also, cross section/spillway locations are shown in the pond area but are not clearly labeled. The release rates for Detention Pond A have been revised to be consistent Page 6 of 10 LOCKWOOD ARCHITECTS, 217 Jefferson, Fort Collins, Colorado 80524. phone: 970,493.1023 fax: 970,493.6765 vacated. Here is an example of a note on another plat that has been filed. THE EASEMENTS SHOWNONLOT 2 OFHIGHLAND A UTOSP. U.D. AND LOT 1 PEDERSEN A UTO PLAZA SUBDIVISION ARE TO BE VACATED WITH THIS PLAT AND REPLACED WITH EASEMENTS AS SHOWN HEREON. The requested note has been added to the plat. Comment # 8: Don't need the sight distance easement language, as there is not a sight distance easement on this plat. The sight distance easement note has been removed from the plat. Comment # 9: Label the street width and easement widths. The street width and easement widths now appear on the plat. Comment # 10: Make changes as shown or add information as needed to the general notes. The changes and additional information are reflected in the plat. Comment # 11: Indicate that the plat is to be included in this set after the cover sheet. The plat is now included in the overall utility plan set, as requested. Comment # 12: Do not indicate that work is to be done by others. The developer is responsible for all work shown on these plans. You can have agreements with someone else to do the work, but everything shown on the plans will need to be done with this project. The note, `By Others" has been removed from the utility plan. Comment # 13: Missing some sidewalks and crosswalks on the utility plans that are shown on the site plan. The engineering drawings have been updated to include the additional sidewalk and crosswalks, as requested. Comment # 14.• Need to indicate that the streetpatch is to be in accordance with City standards with exact limits to be determined by the City inspector. The limits of the street patch have been revised, in addition to adding the note requested. Comment # 1 S: Label the 7 foot high fence on the utility plans. Page 5 of 10 LOCKWOOD ARCHITECTS, 217 Jefferson, Fort Collins, Colorado 80524. phone: 970.493.1023 fax: 970.493.6765 Con ENGINEERING - Issue Contact: Sheri Wamhoff Comment # 1: Need to provide a detail of the textured and painted x-walks that are shown on the site plan. A note has been added to the site plan that the textured and painted crosswalks are to match the existing crosswalks. Comment # 2: Use detail 7-29B for the driveway cut. Identify t = 8 inches min, identify the radius and width of the drive as well as on this detail. The drive radii should be 20 feet per 8.2.9.A. Table 8-2. Provide this detail. Detail 7-29B has been added to the detail sheet, as requested. Additionally, the drive radii is 20 feet. Comment # 3: Showing two lots and labeling as such, but have a note that the lot line goes away with the plat. Where is the division between the two lots then? Just one lot. (See label on plat) Comment # 4: Need to show the retaining walls on the Site and Landscape Plans. Also need to show where the steel handrail is to be located. Done Comment # 5: The drainage easements are not correctly shown on the Site and Landscape Plans. Done Comment # 6: The building envelope can not extend over the easements. The proposed 10' utility easement has been notched to accommodate the proposed building, as previously agreed to by Jeff Hill, per coordination with him, prior to the previous submittal. Comment # 7: Make changes to the plat language as shown. Note #2 on the plat. Doesn't make sense as written. 1 am guessing that the intent of this note is that the easements shown on the prior plats should be Page 4 of 10 LOCKWOOD ARCHITECTS, 217 Jefferson, Fort Collins, Colorado 80524. phone: 970.493,1023 fax: 970.493.6765 variance that Detention Pond A does not have a full one -foot of freeboard. Comment # 40: Stormwater has indicated that the proposed water quality outlet structure is not consistent with what the City uses. The proposed water quality structure is indeed consistent with the structures currently being used by the City of Fort Collins. The structure has been designed in accordance with the Urban Storm Drainage Criteria Manual, Volume 3— Best Management Practices updated in September of 1999. The proposed structure has been customized to be built into the walls of Detention Pond A. Details have been added to the construction drawings for the well -screen trash rack, which is consistent with what the City uses. Comment # 41: Stormwater has indicated that letters of intent from the affected property owners for the necessary of -site improvements must be provided to the City. A telephone conversation with Wes Lamarque of the City of Fort Collins Stormwater Department on August 16, 2001 confirmed that permission was not required from the off -site property owners due to the precedence of ponding already being approved for those properties. He did suggest that a letter be written to the affected property owners as a courtesy to remind them of the existing drainage easements and/or approved extents of ponding, and to inform of the activities that will take place with the Pedersen Auto Plaza Expansion. A copy of these letters will also be provided to the City, but neither written permission nor approval is required from the off -site property owners. Comment # 42: Will the expansion of this facility generate new employees? Yes - It is estimated that between 10 to 16 new jobs would be created. Comment # 43: The landscaping to be used for screening of parking and vehicle display areas along Mason Street is either too short (less than 30') or does not extend far enough to provide 70% screening (see the red -lined Landscape Plan). Additional plant material has been placed for proper screening. The plant material proposed is consistent with the existing Landscape concept to the south. Comment # 44: Please contact the City's Transportation Planning Department to discuss the timing for construction of the previously approved trail access from Mason Street to the Mason Street Multi -modal Corridor (soon to be under construction). Page 3 of 10 LOCKWOOD ARCHITECTS, 217 Jefferson, Fort Collins, Colorado 80524. phone: 970.493.1023 fax: 970.493.6765 Comment # 34: Engineering does not really want the textured and painted pedestrian crossing in the Mason Street right-of-way. However, Transportation Planning would like this to remain to match the existing crosswalk on the original site. It is intended for the proposed new crossing to match the existing crossing to the south. City Staff needs to resolve their own conflict and advise us accordingly. Comment # 35: The retaining walls for the detention pond should be shown on the Site and Landscape Plans. Done Comment # 36: Engineering has asked why there is a steel retaining handrail? The retaining wall in this area is greater than 30". Comment # 37: Engineering has indicated that the building envelope extends into an easement. This is not permitted. The proposed 10' utility easement has been notched to accommodate the building, as previously agreed to by Jeff Hill, per coordination with him, prior to previous submittal. Comment # 38: Off -site drainage and construction easements are needed. They must be provided, reviewed, and accepted by the City prior to scheduling this item for public hearing. A telephone conversation with Wes Lamarque of the City of Fort Collins Stormwater Department on August 16, 2001 confirmed that the ponding being proposed with the Pedersen Auto Plaza Expansion lies within existing drainage easements and/or extents of ponding as dictated by construction drawings designed by Stewart & Associates, and approved by the City of Fort Collins. Furthermore, the addition of the horizontal orifice plates will be done in such as manner so that no temporary construction easements will be needed. Comment # 39: Stormwater has indicated that the detention pond needs freeboard. A variance is being requested for the City's detention pond freeboard requirement. This variance request appears in the written text of the drainage report. The variance is needed in order to provide the entire detention volume on top of the water quality capture volume. According to redline comments by Wes Lamarque of the City's Stormwater Department that appear in the drainage report, the City has accepted the Page 2 of 10 LOCKWOOD ARCHITECTS, 217 Jefferson, Fort Collins, Colorado 80524. phone: 970.493.1023 fax: 970.493.6765 23 August 20011 Planning & Zoning Board c% Planning Dept. 281 N.
