Title

Forester Creek Improvement Project (CIP99-21)

Description

CDFG is intending to execute a Lake and Streambed Alteration Agreement number 1600-2003-5090-R5 pursuant to Section 1602 of the Fish and Game Code to the project applicant, City of Santee. The applicant proposes to alter the stream to modify the extreme downstream portion of Forester Creek as it runs through Santee from Prospect Avenue to north of Mission Gorge Road in order to achieve 100-year flood protection. The basic components of the project consist of: a widened channel revegetated with freshwater marsh in the middle and willow scrub on the sides; an extension of Olive Lane southward from Via Zapador to Prospect Avenue; a new bridge over Forester Creek on the extension of Olive Lane; a bicycle path along the south bank of the new channel, and a bicyclist rest stop where the existing creek bows to the south; an extension of Mission Gorge Road bridge and widening of the channel underneath the bridge and downstream to the existing energy dissipation structure; and raised channel banks along both sides of the widened creek to prevent water overflows. Downstream of Mission Gorge Road Bridge, approximately the southern third of the existing concrete-lined channel would be acceptable channel slopes. In addition, sewer lines, a water main, San Diego Gas and Electric gas mains, and SBC Communications facilities will be relocated. The northern 2/3s of the existing concrete-lined channel and the existing splitter wall would remain in place. The channel would be widened to a total of 250 feet, and the widened channel bottom would be protected from erosion by installing open stabilization material. The existing energy dissipation structure would be widened to extend across the new channel. From Mission Gorge Road to Prospect Avenue, the widened channel will consist of an earthen and revegetated cross section except under bridges. Under Mission Gorge Road Bridge, the existing grouted rip rap would be replaced across the new widened bottom of the channel with a smooth concrete lining to protect existing shallow utilities. The SR 52 bridge to be constructed by Caltrans will have rip rap side slope protection and the channel bottom will remain earthern. The Olive Lane bridge will have open stabilization on the channel sides and bottom for scour protection of the bridge piers. Energy dissipation facilities will be constructed at the upstream end of the unlined channel to slow water entering from the concrete-lined portion of the channel originating in El Cajon. The project is located in Forester Creek from Prospect Avenue to north of Mission Gorge Road in the City of Santee, San Diego County.
