Home My WebLink AboutFREY STREET COTTAGES SUBDIVISION - FDP - 17-06/A - CORRESPONDENCE - (6)the invert of the pond. Grading should show final grading and determine if wing walls are needed for the outlet structure. Number: 103 Created: 3/30/2007 [3/30/07] The detention pond should have a 2% slope along the bottom of the pond or include a drainage pan with a .5% slope. In past experiences, flat pond bottoms are not graded exact and end up holding water. The City has received many complaint calls when detention ponds do not drain properly and hold water, especially with West Nile virus. Department: Stormwater-Water-Wastewater Issue Contact: Roger Buffington Topic: Water/WW Number: 57 Created: 9/8/2006 [3/27/071 Potholing of the water main was completed. There is marginally enough separation between the intake and the existing water main. Include the blown -up detail showing the separation on the plan so that the contractor and the inspector are aware of the expectations during construction. [2/12/07] (Repeat comment... again) [1/2/07] (Repeat comment) [9/8/06] Move area inlet in Frey to provide 5 feet (minimum) separation from the existing water main. Be sure and return all of your redlined plans when you re -submit. If you have any questions regarding these issues or any other issues related to this project, please feel free to call me at (970) 221-6750. Sincerely, Anne Aspen City Planner Page 4 [2/13/07] PFA has no further comments or concerns. Department: Stormwater-Water-Wastewater Issue Contact: Glen Schlueter Topic: Stormwater Number: 99 Created: 2/23/2007 [2/23/07] Red lines were not returned for the Feb. submittal. A drainage report was requested last week but was not submitted to Stormwater so the Engineering copy was reviewed. There was no mention of verification of the outfall depth and no discussion of why the cross pan was removed allowing water off of LaPorte to drain onto Frey. This change requires changes to the drainage anaylsis. I had a phone conversation with Jerry from Stewart and Associates when we requested the drainage report. He thought Wes had made �T the comment to remove the cross pan at Laporte. Wes didn't make that comment so we are�P' not sure how Jerry thought that. He told me that he saw a redline comment so I guess wed`\, J need to see the redlines. �c9 i Department: Stormwater-Water-Wastewater Issue Contact: Wes Lamarque Topic: Stormwater Number: 44 Created: 7/28/2006 0 [3/28/07] Reminder Comment.

[2/23/071 [1/5/07] Please use the current revised water quality outlet structure detail. An electronic copy can be emailed to you. Number: 79 Created: 1 /5/2007 [3/28/07] The area inlets need to be centered with the flowline on each side of Frey Street. CDOT Type 13 Area Inlets (Plan No. M-604-13) will work for this design and be acceptable by the City. The only modification to this detail is to include a bicycle safe grate instead of the standard one. Please specify a bicycle safe grate including manufacturer and identification number and include all details in the plan set. After looking in the report, the grate is specified. Please include the new inlet detail and the grate shown in the report in the utility plan set. [2/23/07] [1/5/07] Please coordinate with the Stormwater Department on the detail for the area inlets. Electronic Inlet details can be emailed as well. Number: 101 Created: 3/29/2007 [3/29/07] The water quality orifice calculations in the report are for extended detention, but with the use of a riser pipe, not an orifice plate. Please use the table in Volume 3 of the Urban Drainage manual that is for extended detention with the use of an orifice plate. Number: 102 Created: 3/30/2007 [3/30/07] The grading plan show a lower pond invert than what is in the report and on the outlet structure detail. The invert should be at 42.5. Also, the outlet structure is not set at Page 3 s� Department: Engineering Issue Contact: Randy Maizland Topic: Engineering r Number: 85 Created: 1 /8/2007 [2/6/07] Drainage report does not address flows coming off of Laporte going into the new d� proposed inlet on Frey. [1/8/07] If Laporte drainage is intended to be conveyed to Frey and into the proposed inlet, have the inlets and storm drain been sized to carry these flows ? Please provide hydrology calc's to verify this. Number: 86 Created: 1 /8/2007 [2/6/07] Intersection has changed to a T intersection without a pan. Still need to show all spot elevations and dimensions per LCUASS 7-28. You can show this on the current plan ori' provide a separate intersection detail showing all of the required elevation, dimension and slope information. [1/8/07] Please provide radii and all spot elevations per LCUASS Figure 7-27 at the intersection of Frey & LaPorte. Number: 88 Created: 1 /8/2007 [2/6/07] Repeat comment. [1/8/07] Show and label the approximate limits of street cut to construct Frey where it ties into Laporte. Please add the City standard street cut note to the Frey Street Plan. Note is attached to the redlines. Number: 90 Created: 2/5/2007 [2/5/07] Please refer to sheet 6, street design for Frey Street - The City has determined that the elevations on Laporte will be slightly lower when the street is reconstructed in the near future. A design elevation of 5047.79 was provided to you prior to the last submittal which is the future elevation at the westerly PC on the southwest corner. You will need to design and build to that future elevation for the drainage to work properly once Laporte is reconstructed by the City. Please revise the plan to show this elevation and how the new curb and gutter will tie back into the existing curb and gutter on Laporte. Number: 91 Created: 2/6/2007 [2/6/07] Please call out the new proposed H.C. ramps with LCUASS standard drawing 1606 on the street plan for Frey Street.

How will theremoval of such trees be done so that the protected trees will not be damaged? [2/2/07] Address protection of significant existing trees where other trees will be removed. Several trees to be removed are very close to trees to remain. Need to identify proection measures specifically for such trees. [1/2/07] Describe tree protection methods in areas where other trees are to be removed. Need to ensure that removing one tree does not damage another tree. Department: Current Planning Issue Contact: Anne Aspen Topic: Site Exhibit Number: 96 Created: 2/13/2007 [2/13/07] Maximum height in the NCL zone is 2 stories, not 30 feet. A story is defined in the �� Land Use Code as no more than 12.5 feet, so the maximum height in feet would be 25 feet. V0V0(*%- .� C Department: Current Planning Issue Contact: Dana Leavitt Topic: Utility Plans ` Number: 100 Created:3/19/2007 [3/19/07] Add the protected trees to the grading plan. There appears to be significant amounts of grading aroundthe majority of protected trees. Tree specification standards limit cut and fill to 4" or less around protected trees. If this is unattainable, set up meeting with Tim Buchanan and Dana Leavitt to discuss further mitigation measures. ,,0 X Page 1 a0` (/ C k \� �Nsr ��
