Collins Storm Water Utility 235 Mathews Street Ft. Collins, Colorado 80524 RE: Drainage Analysis for Mountain - Oak Neighborhood, Old Town Basin, Fort Collins, Colorado Dear Mr. Schlueter: We have completed a drainage analysis for Mountain - Oak Neighborhood situated in the Old Town Drainage Basin, Ft. Collins, Colorado. It is our understanding that the proposed development plan consists of the following: 1. Removal of two (2) out structures. 2. Construction of a 4-car garage behind the existing residence/office located at 420 West Oak Street. 3. One new residence on the remaining open lot in the block. 4. An addition on to an existing residence/office at 420 West Oak Street. 5. An access drive parking area for the proposed garage constructed using checker blocks. The purpose of the checker blocks is to provide more pervious surface in the drive/parking lot than a typical paved lot would provide. The blocks also provide a more aesthetically pleasing parking lot which will help to improve the residential atmosphere of the neighborhood. Our calculations have shown that there is negligible increase in runoff from the block due to the proposed improvements. Due to the size of the contributing area studied (2.2 acres), the runoff both historical and developed is minimal and would have absolutely no impact on the Old Town Basin. Detention facilities would not be justified for this situation. If you have questions, ple Since , ll ,G2 Brian W. Shear, P.E.
