HomeMy WebLinkAboutCDOT POUDRE RIVER REST AREA - SITE PLAN ADVISORY REVIEW - 27-04 - CORRESPONDENCE - (3)12. The proposed changes to Prospect Road, lane widening and adding turn lanes, do not appear to be addressed at all in the modeling. Please add if necessary, or at least discuss in the report why these changes do not need to be modeled. 13. Does CDOT own property to the east of Boxelder Creek? Particularly, in the area showing a rise? 14. Since the proposed project schedule has been delayed, the FEMA Map Modernization project is now playing a part in how this project is reviewed. The bottom line is, the City needs to submit the new Boxelder floodplain mapping to FEMA by the end of September. Since this project will not be completed by then, we need to ensure what is proposed will ensure approval by FEMA. Based on conversations between CDOT (Pete Graham), the City (Susan Hayes) and FEMA (Dan Carlson) it was agreed that the hydraulic analysis of the site would be submitted to FEMA along with the City's mapping for the Map Modernization process. This would assure CDOT that their proposed changes to the floodplain are acceptable to FEMA and will be incorporated into the map upon completion of the project. Department: Transportation Planning Issue Contact: Mark Jackson Topic: Transportation Planning Number: 11 Created: 8/3/2004 [8/3/04] Per previous discussions with the CDOT/Stantec team, please add pedestrian connections from rest area, along frontage road to Prospect. We had talked about the importance of providing safe pedestrian facilities for rest area visitors to walk over to interstate commercial areas when developed. Is the plan still to construct the frontage road south of Prospect to match the cross section north of Prospect (e.g. bike lanes, c&g, sidewalk, etc.?) Show bike lane detail on site plan for frontage road. Number: 12 Created: 8/3/2004 [8/3/04] Please make certain adequate bike parking is installed at rest area. Department: Zoning Issue Contact: Peter Barnes Topic: zoning Number: 3 Created: 7/16/2004 [7/16/04] No comments Please 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, Cameron Gloss Current Planning Director Page 6 release rate that matches the historic flows from existing basin EX2, and not from the entire area draining into the ponds. The release rate would be the 2-year historic flow rate for basin EX2, or the 100-year historic flow rate for basin EX2 if previously mentioned conditions are met. Again, if it is proven that there is no negative impact to properties downstream, a release rate higher than the 100-year historic flow rate of basin EX2 and equal to the 100-year historic flow rate of the entire area draining into the ponds can be used. A meeting may want to be scheduled to further clarify this issue. Number: 26 Created: 8/6/2004 Further comments may follow once more information is submitted. Topic: Floodplain Number: 25 Created: 8/5/2004 1. The following comments are not complete since the modeling work of Stantec is not complete (per Dawn Gladwell). There may be additional comments after the full modeling report is submitted. 2. Please check the floodplain boundaries on the Site Plan. They don't appear to be correct. 3. Any fencing in the floodway will have to be break -away and cabled to prevent floating downstream. 4. Please add the floodplain/floodway to the Landscaping Plan and add a note stating any changes to landscaping in the floodway must be approved by Stormwater. 5. Make sure not only the grading, but also the landscaping material is modeled in the Modeling Report. Shrubs and evergreen trees can be a barrier to flow. 6. With the revision of the new city mapping to show the as -built topo for the Welcome Center, there is now a portion of the site that is outside the city floodplain but still in the effective FEMA floodplain. This will not be changed until the new mapping is adopted by FEMA, in approximately 18 months. The only way to change the map is to submit a map revision to FEMA. This will be addressed with the submittal in 14 below. 7. In the report, the building square footage is smaller than stated in the Planning Objectives document. Please ensure you are modeling the correct building. 8. On page 4 there is a reference to "future plans will include the Welcome Center." Please clarify if this means there will be a new building or the Welcome Center will be housed in the building shown on the plans. 9. The proposed garage must also meet floodplain regulations. To meet the floodplain regulations it can either be elevated or built at -grade with venting. Unfinished up to the regulatory flood elevation and all hazardous materials inside stored above the regulatory flood elevation. 10. On pages 6 and 12, please remove reference to the model being produced at the master plan level. This is not applicable to floodplain mapping. 11. Page 6, Corrected Effective: add reference to using the as -built topo for the Welcome Center in addition to the 1999 topo.

However, if an analysis can show that releasing at the 100-year historic rate does not have a negative impact on the river and downstream property between the site and the river, this 100-year historic rate can be used. Number: 15 Created: 8/4/2004 Due to site flows draining from one detention pond to another, the conveyance between the ponds needs to be sized for the entire 100-year flow of the upstream basin or an Extran analysis needs to show the timing of the flows and tailwater conditions will work with this design. Extran would normally be required for sites larger than 20 acres. Number: 16 Created: 8/4/2004 The developed flows from existing subbasin EX3 that drain to the south field are draining into an area with no defined outfall. This is allowed without a drainage easement downstream only if the flow has not increased in peak discharge, increased in volume of flow, and changed in character or quality of flow. Due to the site design redirecting some of the flows in basin EX3 to Boxleder Creek, the above conditions are more likely possible. The report also needs to document what condition the existing outfall swale is in and if any improvements are necessary. The Natural Resource department will need to accept the runoff as shown. They may require an easement. Please contact Doug Moore @ 224-6143. Number: 23 Created: 8/5/2004 The report text has a lot of inconsistencies when compared to what is actually designed. Please update the text to what is actually being proposed. Number: 24 Created: 8/5/2004 The design is proposing to transfer flows from the Poudre Basin into the Boxelder Creek Basin. Due to this site being at the downstream end of the basins and the area in the Poudre Basin having no defined outfall, this design will be acceptable if proven that no negative impacts are created downstream in the Boxelder Creek Basin. A general rule when transferring or redirecting flows from one basin to another is that the detention ponds that release into Boxelder Creek would need to have a Page 4 A fire lane is required. The fire lane shall be visible by painting and signage, and maintained unobstructed. 1997 UFC 901.2.2.1; 901.3; 901.4.2; 902.2.1; FCLUC Number: 18 Created: 8/4/2004 [8/4/04] PREMISES IDENTIFICATION: Approved numerals or addresses shall be provided for all new and existing building in such a position as to be plainly visible and legible from the street or road fronting the property. 1997 UFC 901.4.4 A.

Date:08/06/2004 DALE STEIN 209 S. MELDRUM FT. COLLINS, CO 80521 Staff has reviewed your submittal for CDOT POUDRE RIVER REST AREA PDP - SITE PLAN ADVISORY REVIEW - TYPE II, and we offer the following comments: ISSUES: Department: Engineering Issue Contact: Katie Moore Topic: General Number: 6 Created: 8/3/2004 [8/3/04] Through documents provided by Stantec, in conjunction with analyzing additional documents with the City's Chief Surveyor, it appears that Prospect Road is within City Right -of -Way to a point approximately 410 feet east of the centerline of the frontage road intersection with Prospect. The frontage road is also City property, with an overlying access easement granted to CDOT. Since both of these roadways are City -owned, improvements to the roadways should be made to City standards. Please see the Larimer County Urban Area Street Standards for the applicable regulations. The frontage road is designated as a collector street on the City's Master Street Plan, and should be improved to collector standards (without parking) along the Rest Area property frontage. Design of the Frontage Road should be provided for the property frontage, plus preliminary offsite design for 500' per LCUASS. Please note that the City understands that the cross-section for Prospect will not include curb and gutter. Please provide more detailed plan and profile sheets for these street designs, and please show CDOT ROW/easements vs. City ROW/easements very clearly on these plans. Number: 7 Created: 8/3/2004 [8/3/04] Who will build, own, and maintain the traffic lights proposed? CDOT? Number: 8 Created: 8/3/2004 [8/3/04] It appears that there is a small structure on the south side of the Rest Area with a driveway that comes in from the south through a gate in the fence. This driveway appears to cross over City property in some fashion. Please show where this driveway goes. Is there an existing easement for it? If not, this is another easement (in addition to the 50' temporary construction easement along the northwest property line) that would need Council approval, and legals should be submitted for processing very soon. Number: 9 Created: 8/3/2004 [8/3/04] Please provide utility plans per LCUASS specs, with a standard cover sheet, city signature blocks, etc. Page 1
