RE: Otter Products Building — 252 East Mountain Avenue
Glen,
City of Ft. Collins ved Plans
Approved By A.
Date I -Is- 0-7
This is letter is in regard to the Otter Products Building on West Mountain Avenue adjacent to the
Food Co-op, more specifically, the drainage analysis for the site. The lot is approximately 0.13 acres,
with an existing building and asphalt parking lot, the entire site is currently 100% impervious. The
site is located within the Old Town Drainage Basin; drainage from the site enters the Oak Street
Outfall system via curb inlets on Mountain Avenue and Walnut Street; water quality treatment is
currently accomplished with the Udall Ponds.
Proposed for the site is a 4-story mixed -use building that occupies the entirety of the lot, demolishing
the existing building and parking lot. Roof drains are to convey water into the existing storm outfall
system without draining over the sidewalk. The developed flows from this site will be the same as the
current flows, as the new site layout is also 100% impervious.
In essence, the redevelopment of this lot will not have a significant impact on the current drainage
flows and patterns within the Old Town Drainage Basin. Please reference the Utility Plans for spot
grades and finish floor elevations.
Please feel free to call with any questions you may have regarding this analysis.
