The Flood Insurance Rate Map (FIRM) for a community depicts the floodplain, the area which has been determined to be subject to a 1% (100-year) or greater chance of flooding in any given year. The floodway is the portion of the floodplain that includes the channel of a river or other watercourse and the adjacent land area that must be reserved in order to discharge the base flood without cumulatively increasing the water-surface elevation by more than a designated height. The FIRM is used to help the community with floodplain management.
Shasta County is applying for a Letter of Map Revision (LOMR) from the Federal Emergency Management Agency (DHS-FEMA) on behalf of Jesse Pyorre to revise FIRM number 06089C, panels 1580J, 1590H, and 1595H for Shasta County along Cow Creek, Little Cow Creek, Oak Run Creek, and Clover Creek. Jesse Pyorre is proposing to revise FIRM to reflect corrected channel data.
The Shasta County Department of Public Works, in accordance with National Flood Insurance Program regulation 65.7(b)(1), hereby gives notice of the County's intent to revise the flood hazard information, generally located between Highway 44 and the confluence with Old Cow Creek. Specifically, the flood hazard information shall be revised along Cow Creek from approximately 900 feet upstream of Highway 44 to approximately 2,300 feet downstream of the confluence with Old Cow Creek, and along Little Cow Creek from approximately 1,130 feet upstream of the confluence with Cow Creek to approximately 150 feet upstream of Old 44 Drive, and along Old Run Creek from the confluence with Cow Creek to approximately 1,900 feet downstream of Old 44 Drive, and along Clover Creek from the confluence with Cow Creek to approximately 1,250 feet upstream of the confluence with Cow Creek.
As a result of the revision, the floodway shall widen and narrow, the 1% annual chance water-surface elevations shall increase and decrease, and the 1% annual chance floodplain shall widen and narrow within the area of revision.
Maps and detailed analysis of the revision can be reviewed at the Shasta County Department of Public Works at 1855 Placer Street Redding, CA 96001. Interested persons may call William Miller, Supervising Engineer, at (530) 225-5661 for additional information from 8:00 a.m. to 5:00 p.m. Monday through Friday.
