REQUESTED COMMISSION ACTION:
The applicant requests a Floodplain Use by Special Exception to modify the Slaughterhouse Gulch floodplain delineation located at the intersection of S. Delaware Street and W. Powers Avenue by placing fill.
BACKGROUND:
The Slaughterhouse Gulch is a Federal Emergency Management Agency (FEMA) floodplain in the subject area, as depicted on the Flood Insurance Rate Map (FIRM) for Arapahoe County, Colorado. The 100-year floodplain is located in the streets and on residential properties, without a defined channel. A 60-inch storm sewer pipe conveys a portion of the floodwaters. Homes are located in the floodplain. The proposed grading activity will place fill to elevate the property in the northeast corner of S. Delaware Street and W. Powers Avenue above and out the floodplain. The project will require a Conditional Letter of Map Revision (CLOMR) from FEMA before construction, in addition to a Letter of Map Revision (LOMR) after construction is completed.
STAFF ANALYSIS:
Staff finds that the application meets the requirements of Littleton Municipal Code Title 10, Chapter 6 (floodplain regulations). Staff has evaluated the hydraulic model prepared by the applicant and found it to be representative of the existing conditions and proposed fill activity. The project will not increase risk to public health, safety, and general welfare, and will minimize public and private losses due to flooding.
