1.0 GENERAL LOCATION AND DESCRIPTION
This document is the Preliminary Drainage Report for Kum & Go #0951 (the “SITE”). The
purpose of this report is to identify onsite and offsite drainage patterns, storm sewer, inlet
locations, and areas tributary to the site with the goal of safely routing developed storm
water runoff to adequate outfall facilities.
The proposed project is located within at 949 E Prospect Road, being a portion of the
northwest quarter of Section 24, Township 7 North, Range 69 west of the 6th P.M., City of
Fort Collins, County of Larimer, State of Colorado. The proposed site is bordered on the
north by Prospect Road, on the east by Lemay Avenue, and on the west and south by
residential houses.
Currently the site consists of a convenience store with two fuel pumps, three single story
houses, two garages, a storage shed, and a concrete retaining wall. Development of the
site will require demolition of the existing structures, as well as the convenience’s store
fuel pumps and concrete retaining wall. The proposed area of improvements is 1.46 acres
while the proposed Kum & Go property is to be 0.91 acres. The remainder 0.55 acres is
to be for improvements to the adjacent right-of-way along Lemay Avenue and Prospect
Road.
Based on the NRCS soil survey, the entirety of the soil present on the site is classified as
Hydrologic Group C. The site generally slopes away from each of the existing structures.
There are curb inlets located adjacent to the property along E Prospect Road and S Lemay
Avenue.
Changes to the site grading are proposed to ensure proper drainage around the proposed
building and parking lot. These changes will include installation of curb, gutter, concrete
paving, storm sewer infrastructure, and an underground detention facility.
Per FEMA Map Panel 08069C0983H, dated May 2nd, 2012, the majority of the site is within
Zone X, Area of Minimal Flood Hazard. The southern property line and western curb and
gutter of Lemay Avenue are within Zone AE, with small portions crossing into the subject
property.
The proposed building and canopy will both be within Zone X.
Please cite compliance with Chapter 10 of City Municipal Code.
Also mention that a Floodplain Use permit will be obtained prior to start of construction
for work in the floodplain.
