Also, please see the response to comments provided by JR Engineering in their response letter. Mike Brake from JR Engineering has been in contact with the City to address these issues and the City has reviewed these plans prior to this resubmittal. Department: Transportation Planning Issue Contact: Tom Reiff Topic: General Number:33 Created:11/12/2003 [11/12/03] No further comments. So noted. Thank you. Department: Zoning Issue Contact: Jenny Nuckols Topic: ZONING Number:31 Created:11/4/2003 [11/4/03] No comment So noted. Thank you. The project is considered to be ready for a Planning and Zoning Board public hearing and it has been placed on the January 15, 2004 Board hearing agenda. The following items are needed by the dates indicated below: 1 8.5" x 11.0" reduced copy of each of the 3 sheets of the Overall Development Plans, by Wednesday, December 31s` 8 full-size paper copies (folded) of the 3 sheet set of Overall Development Plans, by Friday, January 2nd The aforementioned plans have been included in this resubmittal. The requested quantity of plans as per the routing sheet has also been included in this resubmittal. Also included in this submittal is a )peg file of the ODP for inclusion in the City's power point presentation. The applicant will submit a' complete power point presentation to staff on January 7, 2004. Please be sure and return all of the City staff red -lined plans when you submit the above documents. The redlined plans have been included in this resubmittal. Page 5 con@@ o urban design, inc. line is shown in its entirety. Please use the work maps to correctly site the Cooper Slough floodplain. Since there are two regulatory floodplains (City and FEMA) analysis for both conditions shall be required at time of design of any facility in the floodplain. Because a floodway is not mapped in the FEMA floodplain, the floodplain is considered "no -rise". This means that you can not cause a rise in the flood level off of your property without obtaining easements from affected property owners. Any changes that are made to the no -rise floodplain or in the recently adopted floodway (fill, plantings, construction of buildings, culverts, channels, bridges, bikepaths, etc.) will need to be modeled by a registered professional engineer to document no -rise. A $300 fee is required if hydraulic modeling is necessary. Please use the City's Floodplain Modeling Guidelines for the preparation of this analysis. Please include the benchmark number and elevation being used for the site. On Sheets 2 and 3 for the Overall Development Plan, what does "Future Extents of Amended Floodplain Per JR Engineering" mean? This is not discussed in the report. Please clarify. There needs to be sufficient notes pertaining to the floodplain and regulations on both the Overall Drainage Plan and Overall Development Plan sheets. Please add the following notes to the plans: Any residential structures in the floodplain must have the lowest floor including basement or crawl space elevated 18" above the most restrictive 100-year flood level. Any non-residential structures in the floodplain must either have the lowest floor including basement or crawl space elevated 18" above the most restrictive 100-year flood level or be floodproofed 18" above the 100-year flood level. Critical facilities are not allowed to be built in the most restrictive 100-year floodplain. Please see Chapter 10 of City Code for the definition of critical facilities. A floodplain use permit and $25 permit fee will be required for each structure that is built in the floodplain. To obtain a CO, an elevation certificate or floodproofing certificate will be required to be submitted and approved. A floodplain use permit and $25 permit fee will be required for any construction activity in the floodplain including construction of the detention ponds and any roads. All utilities within the most restrictive 100-year floodplain shall be designed to minimize or eliminate infiltration of floodwaters into the systems and discharge from the systems into floodwaters. In the report please discuss the erosion buffer limits and how they will affect the design of the bridge crossing and any other drainage features. At time of PDP please use the Floodplain Review Checklist to aid in the development of a complete submittal. Page 4 C 0 0�72@@P(A� urban design, inc. Topic: Floodplain Management Number:4 Created:9/9/2003 [11 /17/031 Interstate Lands ODP 11/11/03 Floodplain Management Comments Susan Hayes 1. The floodway for the revised Cooper Slough/Boxelder floodplain has been adopted and will be applied to this site as it develops. Please remove the reference to "proposed" floodway in the report. (Repeat comment for report.) Please see the response to comments provided by JR Engineering in their response letter. 2. Show both the current FEMA floodplains (including Cooper Slough) and the revised floodplain/floodway on the drawings. It's not clear on the ODP plan whether the floodway line is shown in its entirety. (Repeat comment.) Modify legend on the Overall Drainage Plan. Add Floodway to legend on Sheet 2 of the Overall Development Plan. Floodplain lines are still very difficult to see. A request has been put into the Engineer to provide a version of the Overall Drainage Plan with just the floodplain lines so we can review it before approval. Please see the response to comments provided by JR Engineering in their response letter. 3. Please use the FEMA work maps to correctly site the Cooper Slough floodplain. (Repeat comment.) It looks like the floodplain is still too far to the west and you have a proposed detention pond located in the correct location. The work maps are located at the Utilities office. Please contact Susan Hayes at 416-2233 to review them. Please see the response to comments provided by JR Engineering in their response letter. 4. Please check the benchmark number and elevation being used for the site. The one shown on the plan does not appear in the City's list, unless it's a new one. Please see the response to comments provided by JR Engineering in their response letter. 9/8/03 Floodplain Management Comments Susan Hayes The floodway for the revised Cooper Slough/Boxelder floodplain has been adopted and will be applied to this site as it develops. Please remove any reference to "proposed" floodway on the drawings and in the report. Show both the current FEMA floodplains (including Cooper Slough) and the revised floodplain/floodway on the drawings.

Topic: Traffic Number:35 Created:11/25/2003 [11/25/03] The proposed point of access on the Frontage Road nearest East Prospect Road must be removed from the ODP. The access point has been removed from the plans as requested. Topic: Utilities Number:34 Created:11/25/2003 [11/25/03] Mike Scheid of the East Larimer County Water District indicated that red -lined remarks were made on the included utility plan. Please see the response to comments provided by JR Engineering in their response letter. Department: Engineering Issue Contact: Marc Virata Topic: General Number:32 Created:11/10/2003 [11/10/03] The ODP now shows an additional access point onto the Frontage Road immediately north of Prospect Road that was not previously known. The access point is not supported by Engineering and should be removed. Provided this access point is removed, all previous comments appear to be addressed and Engineering considers the project ready for a public hearing. The access point has been removed from the plans as requested. Department: Stormwater Utility Issue Contact: Basil Harridan Topic: Detention Pond Sizing Number:11 Created:9/12/2003 [11 /17/03] Please note that these requirements will need to be met at the PDP stage. It seems that the detention ponds were sized using the rational method. At PDP SWMM modeling will be required, this could have a significant impact on the size of these ponds. The report proposes to release drainage waters from the detention ponds at rates matching the 10 and 100 year storms. It is recommended by the master plan that a 2 year release be done. The matching of the hydrograph in the 10 year storm and the 100 year storm as proposed would only be acceptable if it can be demonstrated at PDP stage that no adverse conditions are caused by such a release.
