HomeMy WebLinkAboutRIGDEN FARM, PIONEER CHARTER SCHOOL - SITE PLAN ADVISORY REVIEW - 56-98U - CORRESPONDENCE - REVISIONSPioneer Charter School August 20, 2003 Page 4 of 4 Number: 9 Enhanced crosswalks are now shown for the bike trail crossing of Kansas and Minnesota Drives. Department: Water Wastewater Number: 19 Proposed water and sewer facilities are now labeled as requested. Number: 20 Easement documentation will be provided prior to final plan approval. Number: 21 The water main shown on the previous submittal has been removed. Number: 22 The sanitary cleanouts have been labeled as traffic rated and a detail added. Number: 23 Rim and invert elevations have been added for the proposed manhole and a detail added. Number: 50 The 8-inch water line off of Minnesota is now labeled to be abandoned at the main and a street patching note has been added. The new water service is shown 5 feet north of the existing 8-inch line in order to minimize the width of street cut required and to avoid the existing street light further north along Minnesota. I trust that all comments have been adequately addressed. However, if you should have any questions regarding these responses or the revised Utility Plans, please do not hesitate to call. Sincerely, Interwest Consulting Group Robert Almirall, P.E. C:\co\pr\03\Pioneer\corres\082003 comment letter Pioneer Charter School August 20, 2003 Page 3 of 4 Number: 45 Excerpts from the Rigden Farm Filing One and Six Reports have been attached to the letter report for this project. These show the original stage -storage table for the onsite pond and the anticipated imperviousness for the site basins. Number: 47 It is intended that a pedestrian bridge from Big R Manufacturers in Greeley, Colorado will be utilized for this site. The bridge and abutment details have not been completed and will be included with the final plan submittal. If available prior to re -submittal, I will forward a copy to the Stormwater Department for review. Number: 46 1. An erosion control report with Performance Standards, Efficiency and surety calculations has been submitted. 2. The Drainage and Erosion Control Plan now shows the BMP measures proposed, including a legend. 3. A note regarding the timing of seeding disturbed areas has been added to the Erosion Control Plan and corrected in the Erosion Control Report. 4. The Larimer County erosion control notes have been removed and replaced with the City of Fort Collins standard notes. Due to space limitations these notes have been added to the General Notes sheet and cross referenced on the Erosion Control Plan. 5. A note has been added to the General Note sheet requiring that future phases of the project will require a separate plan submittal and review. A detailed EC plan for future phases will be submitted at that time. 6. During construction of Ridgen Farm Filing One the lower end of the pond was over excavated for a sediment basin. That condition will remain during construction of this site to facilitate sediment control. The plans also call for a standard culvert inlet protection to be installed at the flared end section to further protect downstream properties. Department: Transportation Planning Number: 6 A cross section has been added to the Utility Plans reflecting the bike and parking lane striping. See comment Number 48 above. Number: 7 Traffic Operations will be contacted to determine the appropriate signage for limiting on -street parking in those two locations. Number: 8 An additional handicap ramp has been added as requested. C:\co\pr\03\Pioneer\corres\082003 comment letter Pioneer Charter School August 20, 2003 Page 2 of 4 determined that these markings were not the responsibility of the original developer, they surely should be shared by the current and previous developers adjacent to these same roadways. Number: 15 With the change to an asphalt parking lot, curb and gutter has been added to the south and east perimeter of the parking lot to direct the runoff to a concentrated release point. Small basin lines have been added to the drawings to reflect the area of sheet flow now being directed toward the driveway entrances. These areas are within the guidelines set forth by the City Engineer and the LCUASS. All concentrated flow is conveyed under the sidewalk via a sidewalk chase system. Number: 16 We apologize for any confusion related to the line types. The plans have been revised to reflect a bolder line weight for the proposed contours. Number: 29 A utility abandonment is now required and the appropriate street cut note has been added to the plans. Department: Natural Resources Number: 49 The note requested has been added to the Drainage and Erosion Control Plan for clarification to the School Contractor. However, this riprap was designed and proposed with the Rigden Farm Filing One project and a reference to that effect has been added to the plan. Department: Stormwater Utility Number: 40 A note has been added to the Utility Plans that the drainage facility is to be privately maintained. Number: 41 We apologize for the oversight. The requested backup data is now attached to the letter report. Number: 42 Detailed spot elevations for construction are now added to the new asphalt parking lot. Curb and gutter has been added to the south and east perimeter of the lot which directs the runoff to a low point on the southern edge. A 2-foot concrete pan and sidewalk chase have been added to direct the flow to the flowline of Custer Drive. Number: 43 A basin summary table has been added to the Drainage and Erosion Control Plan. Number: 44 A sidewalk chase detail has been added to the detail sheet. C:\co\pr\03\Pioneer\corres\082003 comment letter August 20, 2003 Mr. Troy Jones City of Fort Collins 281 College Avenue Fort Collins, CO 80522 INTERWEST = CONSULTING G R O U P RE: Pioneer Charter School - Rigden Farm loth Filing Response Letter for First Submittal Comments Dear Troy: Please find below a response to the city's Staff Project Review comments dated August 6, 2003. I have not repeated the formal comments here but have referenced all responses to the appropriate comment number. The comment/responses below are specifically for items related to the Utility Plans. Additional comments relative to the Site Plan, Landscape Plan or Traffic Study are not included with this document. Department: Engineering Number: 13 All references to `Gravel Pave' have been removed from the drawings. The parking lot is now shown to be constructed entirely of asphalt. Number: 14 Spot elevations and flow arrows have been added to the drawings for the asphalt parking lot. Number: 17 A 20-foot public access easement is now shown around the regional bike trail. The trail has been realigned along Kansas Drive to intersect with the street curb cut opening at the intersection. Minor modifications to the width of this easement may be required pursuant to discussions with Marc Virata to ensure that those future parking stalls do not encroach into the public access easement. Number: 18 The requested note has been added as Project Note 1 on the General Notes sheet. Number: 48 The requested note has been added as Project Note 2 on the General Notes sheet. Pursuant to my conversations with Marc Virata, it does not seem fair that this development would be solely responsible for the full width pavement markings along Kansas, Limon and Minnesota.
