RE: DRAINAGE MEMORANDUM FOR ODELL - NORTH PROJECT
FORT COLLINS, COLORADO
NE PROJECT #: 368-005
Dear Staff:
Northern Engineering Services is pleased to submit this Drainage Memorandum for the Odell North Project
application for your review. The site occupies the lot from the North side of Odell Brewing Company to
Buckingham Street. The subject site is located in the Northeast quarter of Section 12, Township 7 North, Range
69 of the 6th P.M. Fort Collins, Larimer County, Colorado. The site is bounded to the west by 3rd Street, to the
north by Buckingham Street, to the east by Colorado Iron & Metal Inc., and to the south by the Odell Brewing
Company.
This Drainage Memorandum has been prepared in accordance with the Fort Collins Stormwater Criteria Manual
(FCSCM) and Urban Drainage and Flood Control District Criteria Manual (UDFCDCM).
The intent of this project is to remove the large quantities of beet waste currently occupying the lot at depths of
up to 15’ below grade (based on geotechnical investigation performed by CTL|Thompson, Inc.), then re-grade
the lot in a manner that maintains historic drainage patterns with minimal use of imported fill material in
preparation for future expansion of the Odell Brewery parking lot and affordable housing projects. The current
topography is a flattened mound that tends to drain Southward and channels into a swale with an area inlet for
drainage. A re-grading of the lot will prioritize directing runoff to existing stormwater appurtenances in a more
efficient and direct manner.
Current site conditions consist entirely of permeable ground surfaces, with a combination of gravel and native
vegetation. Upon completion of the re-grading, the disturbed areas will be reseeded with native vegetation and
historic drainage pattens will be maintained.
If you have any questions, please feel free to contact me at your earliest convenience.
Sincerely,
NORTHERN ENGINEERING SERVICES, INC.
