HomeMy WebLinkAboutHARMONY SAFEWAY MARKETPLACE PUD - PRELIMINARY - 33-94A - CORRESPONDENCE - RESPONSE TO STAFF REVIEW COMMENTS (3)We also offer the following responses to comments from Kerrie Ashbeck The site will be revised to provide additional turn lanes into the site. This will effect how we grade the open channel parallel to Harmony Road. Our preliminary shows the grading for this channel starting approximately 20' feet from the proposed flowline of the new turn lane. This should be adequate room to provide room for other utilities (not including the new City Main). We are aware however that this turn lane will need to be accounted for. We can extend the culvert under the entry drive onto Harmony Road, providing more room for the meander of the sidewalks/bikepaths. Should there arise other conflicts with the new road alignments, there exists the possibility of piping those portions of the open channel to provide additional room. Please feel free to call if you have any questions regarding this letter, or have any other questions regarding this project. Sincerely, Roger A. Curtiss P.E. cc: Dennis Wyatt, Wyatt and Associates Linda Ripley, Ripley and Associates Kerrie Ashbeck, City of Fort Collins Basil Harridan, City of Fort Collins Roger Buffington, City of Fort Collins by UDFCD. We are also investigating a new pre-treatment structure recently developed by Carder Concrete called Stormceptor. This pre-treatment structure has been used with good results. A representative from Carder Concrete is available and willing to provide the City with a full presentation of the features of this structure. Parallel alternate systems can also be incorporated into final design. We look forward to working with Parks and Recreation to develop a workable system. Item No. 14 - We agree. We can specify on the final construction documents that prior to construction, the contractor will be required to have a coordination meeting with the City Erosion Control inspector to insure the intents of the final Erosion control plan are complied with. Item No. 15 - The client is aware of these improvements. we have had contact with basil Hamdan. Per his direction, we understand that the existing culverts will need to be repaired, and cleaned. This work will be coordinated with the appropriate Ditch co. representative. Item No. 16 - Additional, comments per Stormwater Utility. Items 1, 2, 3, and 4 - These comments bring up concerns that the Stormwater Utility has with the existing master plan for Golden Meadows. Northern Engineering shares these concerns as well. NES has discussed this with Stormwater, and have agreed that more support documentation will.need to be developed at time of final design. Our client does not feel it would be his sole responsibility to provide a completely revised k Master Plan for this region when one exists and has been approved and accepted by the City. They do however agree that they will participate in their fair share of a Master Plan update for this development. This supporting documentation will be provided with final design. In addition, we offer the following response to the Plans set review by Roger Buffington. They offered an alternative routing schematic in the southeast corner of the site. This is a good idea, and we will be incorporating this alternate routing into our final design. Again, we will coordinate the location. of the new City transmission main into our final plans, and locate our improvements accordingly. There is some flexibility in the locations of our necessary drainage facilities, and in previous discussions with Dean Saye w/ Water Utilities, they took into account the existing drainage system in their design of this main. Roger brought forth some questions about service pit locations, fire service lines, irrigation taps, existing service stubs and methods of' abandonments. These questions will be noted and addressed with final construction doCUmCntS. Northern Engineering Services, Inc. April 2, 1996 Mr. Ted Shepard Community Planning and Environmental Services City of Fort Collins PO Box 580 281 North College Avenue Fort Collins, Colorado 80522-0580 RE: Harmony Safeway Marketplace P.U.D. Preliminary Response to City Comments Dear Ted, This letter is in response to the comments regarding engineering issues Northern Engineering Services Inc. (NES) received regarding Harmony Safeway Marketplace P.U.D. Preliminary. Other items related to planning and landscaping will he addressed under separate cover by other consultants. Primarily, our response will he to comments posed by City Water and Wastewater, Stormwater, and Engineering. Response to comments from your letter dated February 8, 1996 to Linda Ripley Item No. 7 - US West concerns have been noted. We would like to arrange it Utility coordination meeting for this project prior to starting final design. We would like to define what "wider" might be. Item No. 8 - The site now has been resurveyed by Landstar Surveying. All existing structures will be shown. Again, a utility coordination meeting will help us with final design. Item No. 12 - We have had preliminary contact with the Water department concerning this main. Your comments indicated this will be used for detention and that is not the case. This area will contain an open channel which will convey stormwater downstream to the Golden Meadows regional detention facility. Cover restrictions will be observed. We will contact Roger Buffington prior to final design to get the most current locations and depths of this main. Should cover become a problem, that portion of the parallel open channel could be conveyed in a pipe system. Item No. 13 - Our client also has concerns about the quality of stormwater runoff leaving the site. We will pre -treat developed runoff according to best management practices as outlined 420 S.
