Based on the survey provided by the City of Fort Collins Survey Departrnent, a final site visit, and discussions with the City Project Manager, we certify that the project is in substantial conformance with the approved plans and drainage report with the following exception: Two sections of 15 inch stone pipe were installed under the PV&L Canal as part of a new outfall for The Ridge Subdivision's pond. Due to depth constraints at the Canal crossing and the existing tie-in elevation at STMH 1, the pipes were designed to be installed at 0.20%. One section of pipe between STMH. 1 and STMH 2 was laid virtually flat as shown on sheet 1 of 1. However, due to the head of The Ridge's pond, we anticipate that this pipe will function adequately. The attached documents show as built elevations for the corridor including storm sewer pipe, storm sewer structures, and swale grades. The attached Record Drawings reflect the entire corridor improvements even though these were shown on various construction plans and constructed in phases by different contractors. Please review this information and give me a call if you have any questions. Sincerely, Robert Almirall, P.E. cc: Mark Laken — City Project Manager 1218 W. ASH, STE.
