HomeMy WebLinkAboutPOUDRE SCHOOL DISTRICT, 2003 ELEMENTARY SCHOOL - SITE PLAN ADVISORY REVIEW - 5-02 - CORRESPONDENCE - REVISIONSMr. Ted Shepard May 29, 2002 Page 10 9. 050102: Sheet 6 — It appears that you need an easement for the riprap and drainage on the west side of Timberline as well as a temporary construction easement. Response: The interim drainage is designed to stay within the existing ROW. The soil riprap can be placed without leaving the ROW. The ultimate drainage design will be directed into inlets within the street and conveyed to existing storm systems. Therefore, the ultimate design stays within the ultimate ROW. 10. 050102: Sheet 7,8 — See redlines for correction to the Crosswalk Markings Note. If there is a study required, then it should be required now, not after the plans are approved. Response: The crosswalk note was corrected per the redlines. Thank you for your review and approval of these plans and responses. If you need further clarification on any of the above responses, please call me (419-1316) at your convenience. Sincerely, Nolte Associates, Inc. Thomas Ochwat, P.E. Senior Engineer NOLTE ASSOCIATES, INC. Mr. Ted Shepard May 29, 2002 Page 9 Response: Nolte Associates, Inc is making the variance request. The letter is included with this submittal. 37. Resolved. 38.

Label all curb return radii on plans. The radius on the NE corner of Timberline and Zephyr needs to be 25' according to table 8-2, LCUASS. Currently shown as a 30'.

A variance request must be submitted in accordance with LCUASS 1.9.2. Did not receive the variance request as noted in the response letter. NOLTE ASSOCIATES, INC. Mr. Ted Shepard May 29, 2002 Page 7 Response: The street capacity calculations have been provided in the drainage report and correspond to design point 400. The inlet has been designed to capture the 10-yr storm and is reflected in the drainage report. During the interim condition, flows will travel in historic patterns into the undeveloped basins 401 and runoff will be picked up in the parking lot inlet at D.P. 200. The Timberline Road Improvements show the existing culvert to be removed. The storm system in Zephyr Road is to be extended to the west of Timberline Road as part of the Timbers P.U.D. This is reflected in the plans. 103.- Please show the Timbers extended pipe on Zephyr and across Timberline to the West. Currently these plans do not show the pipe that is to be extended across Timberline as per the revised Timbers utility plan set. -The proposed 10-foot inlet on the east side of Timberline needs to be tied into the school's storm sewer system. Please indicate on the plans which of the two projects will build this inlet and the tie; will it be done by the road project or the school project? -Inlet design on the Timberline Road: the inlet on the east side of Timberline flow should be designed to carry the 10 year flow through the inlet, while in the 100 year, since Timberline is an arterial street the encroachment in the street should be such that it leaves at least one lane open in each direction. Please design the inlet on Timberline Road and the pipe to meet these design requirements. Response: The Timberline Road Improvements show the existing culvert to be removed. The storm system in Zephyr Road is to be extended to the west of Timberline Road as part of the Timbers P.U.D. This is reflected in the plans. The inlet will be built as part of the road improvements. The inlet has been designed to accept the 10-year runoff as well as the 100-year runoff. During the major storm the water spread is 21.24' that will encroach the remaining lane by 1.24'-leaving a lane width of approximately I V free of water. Timberline Road Improvement Plan (Responses provided by David Evans & Associates) 1. Resolved. 2. Resolved. 3. Resolved. 4. LCUASS 3.2.12 Legend of Symbols — each sheet shall include a legend that identifies the symbols pertaining to the sheet. The legend is missing on a few sheets. NOLTE ASSOCIATES, INC. Mr. Ted Shepard May 29, 2002 Page 6 Response: This ramp is to be used for emergency access and has been designed in accordance with 7-29a. 9. 050102: Show the soccer and baseball fields. Response: Noted and addressed. 10. 050102: Show all utilities. Our standards require this so that we can verify that you are meeting the separation requirements between the utilities and the trees, etc. Response: Noted and addressed. 11. 050102: The City of Fort Collins requires that the information I've asked for be clearly shown on the Site Plan and that they match the Utility and Landscape plans. Your in-house policy is understandable, however these comments will remain unresolved and the plans unapproved until the plans are brought into compliance. Response: Noted Stormwater 102. The plans for the Timberline Road Improvements show the existing culvert under Timberline to be extended and tied into the school's drainage system, while your plans show that the pipe is to be abandoned and removed. Please revise your plans to be consistent with the Timberline Road Improvements Plan. Response: The Timberline Road Improvements show the existing culvert to be removed. The storm system in Zephyr Road is to be extended to the west of Timberline Road as part of the Timbers P.U.D. This is reflected in the plans. 100. The section of pipe between SDI 200 and SDI 201 has very minimal cover; please increase cover on pipe to maintain a 1-foot minimum. Response: Noted 18. Please provide street capacity calculations for Timberline Road. -There is a low point on Timberline Road that is to the north of the proposed improvements. The plans call for a future 10' Type R inlet but there is no sizing that was done and the plans do not show what will happen to street flows in the interim condition. -The existing 18" CMP under Timberline is shown to be merely extended. The City does not allow CMP under the ROW, this pipe will need to be removed and replaced with and RCP culvert. It will need to be sized such that it would be able to handle historic 100-year flows. -No bends are allowed in the storm sewer without a manhole, please correct. Mr. Ted Shepard May 29, 2002 Page 5 policy is understandable, however these comments will remain unresolved and the plans unapproved until the plans are brought into compliance.
