It is further to certify that the attached technical data supports the fact that the proposed Woodward Blue Home Over-lot Grading Plan (Name of Development) will not impact the 100-year flood elevations, floodway elevations, or floodway widths on the Cache la Poudre River (Name of Stream) at published or unpublished cross-sections in the FEMA Flood Insurance Study or the City of Fort Collins Flood Study dated April 16, 2013 CLOMR (FEMA Case No. 13-08-0614R) (Study Dates) in the vicinity of the proposed development. Attached are the following documents that support my findings: 1. Explanation Letter (06-13-13) 2. Over-lot Grading Plan 3. FEMA CLOMR Approval Letter 4. 5. Signature: Name (printed): Bob Almirall Company Name: Interwest Consulting Grp Date: PE Stamp Woodward Blue Home Over-lot Grading Plan 1 No Rise Certification June 13, 2013 Mrs. Marsha Hilmes-Robinson Floodplain Administrator City of Fort Collins Stormwater 700 Wood Street Fort Collins, CO 80525 RE: Woodward Blue Home Over-lot Grading Plan – No Rise Certification Dear Marsha, The Woodward Blue Home development will be approved through the City of Fort Collins through three separate submittal processes. The first submittal will include the site demolition and over-lot grading of the site up to the existing Poudre River Trail that runs along the southern portion of the property. The second submittal will include the demolition and over-lot grading of the remaining property south of the existing trail as well as the trail removal and river bank stabilization work. The final submittal will include the utilities, site work, and building plans for the proposed Woodward Blue Home infrastructure. City Code states that development (including grading operations) in a floodplain must be preceded by a Floodplain Use Permit and, if the work is in a floodway, a No-Rise Certification. The Code also states that if the development in the floodway results in a change to base flood elevations, floodway or flood fringe boundaries, a Conditional Letter of Map Revision (CLOMR) must be approved by FEMA. The proposed Woodward Blue Home over-lot grading plan will impact the floodway and flood fringe boundaries. A CLOMR (FEMA case number 13-08- 0614R) has been prepared for the site by Anderson Consulting and it was approved by FEMA on April 16, 2013 (see attached FEMA approval letter). This No-Rise Certification and supporting documentation is provided to verify that proposed over-lot grading at the Woodward Blue Home site will not impact the CLMOR. The project will include removal of the existing golf course facilities associated with the previous Link-N-Greens golf course as well as over-lot grading north of the existing Poudre River Trail for the proposed Woodward Blue Home project. The entire perimeter of the site will be fenced off with 6’ chain link fence. When this fencing enters the floodway it will become break-away construction fence. Woodward Blue Home Over-lot Grading Plan 2 No Rise Certification Construction staging and storage of material for this project will occur in the central portion of the site and will be located out of the Effective 100-year floodplain. Stockpiling will occur outside the Effective Floodway boundary. Please see the Over-lot Grading Plan for designated construction staging and stockpiling areas as well as the location of the perimeter construction fencing. Following the completion of all three stages of construction (over-lot grading north of the existing trail, over-lot grading south of the existing trail and river bank stabilization, Woodward Blue Home infrastructure), a LOMR will be completed in addition to an as-built No-Rise Certification. The proposed project will meet all standards of Chapter 10 in the City of Fort Collins Municipal Code. I appreciate your time and consideration in reviewing this request. Please call me at 970-460-8487 if you have any questions. Sincerely, Robert Almirall, P.E.
