[CDD CP#06-35] (Contra Costa Flood Control and Water Conservation District Permit Fees) (District III) Flood Control Permit 615-06 (EF0600615) DATE: July 11, 2006 PAGE: 2 of 2 FISCAL IMPACT: The project and associated issuance of the Flood Control Permit will not have an impact on the County General Funds. Funding is 100% Contra Costa Flood Control and Water Conservation District Permit Fees. REASONS FOR RECOMMENDATIONS AND BACKGROUND: The Contra Costa County Flood Control and Water Conservation District(District)is cooperating with the Natural Heritage Institute(NHI)and American Rivers to improve fish passage along Marsh Creek and provide anadromous salmonids access upstream of the drop structure where potential suitable spawning habitat exists,while maintaining the normal operation of the flood control channel. The project consists of small habitat restoration, enhancement, maintenance, and protection for fish, plants, or wildlife. The project will not result in the removal of any scenic resource. Approval of the CEQA.is necessary in order for the District to issue a Flood Control permit to authorize the work and for NHI to submit application packages to the regulatory agencies in support of the cooperative project. CONSEQUENCES OF NEGATIVE ACTION: Delay in approving the project may delay the issuance of necessary flood control permits and real property transactions for the construction of the fish passage project.

What changes to the project-wouId-mitigate the identified impacts: N/A USGS Quad Sheet: Brentwood Base Map Sheet#: J-26 & K-26 Parcel #: N/A GENERAL CONSIDERATIONS: 1. Location: The project is located on Marsh Creek Channel between Delta Road and Sunset Road, in the Brentwood area. (Figs. 1 & 2) 2. Project Description: The purpose of the project is to enhance the existing drop structure on the Marsh Creek Channel in order to facilitate spawning, by installing a fish ladder to allow for fish passage upstream. The District is cooperating with Natural Heritage Institute (NHI) and American Rivers to improve fish passage along Marsh Creek and provide anadromous salmonids access to the upper reaches of the creek where suitable spawning habitat exists, while maintaining the normal operation of the flood control channel. The lower reach of Marsh Creek Channel has been previously re-aligned and channelized to maximize flow conveyance. In order to dissipate the energy of flows, a 5.5 foot drop was installed, which is maintained and operated by the Contra Costa County Flood Control and Water Conservation District (District). The project will include minor modifications to the existing structure including, removing and saw- cutting portions of existing concrete and grouted rock riprap, adjusting the existing rock weir to direct low flows, constructing a fish ladder on the existing drop structure that will be approximately 100 feet in length, with 5 interval steps, gaining 1 foot in elevation at each step until it reaches the top of the drop structure, replacing riprap bank protection, minor conform, and grading of the existing channel. tt: G:\GrpData\EngSvc\ENVIRO\Flood Control\Marsh Crk Drop Structure Rehab (fish ladder)\CEQA\Initial Study(Cat Ex-33);doc Updated: 11/2/04 Page 1 of 2 Marsh Creek Drop Structure Modification-Fish Ladder Passage WL3-FS0500054/ CP#06-35 3x2 During construction, the contractor may have to implement a dewatering system. The design of the system will be at the discretion of the contractor, but will be reviewed by the District and the California Department of Fish and Game. Environmentally Sensitive Area (ESA) fencing will be installed to clearly define the project limits and impact area. Standard Best Management Practices (BMPs) will be implemented such as locating stockpiles outside of the streamzone, fueling and maintaining equipment at designated staging areas, and maintaining a clean worksite. Any exposed soil will be seeded with a mix of native grasses upon completion.of the project. The work will be conducted during the dry season when no salmonid species are present in the creek. No tree removal will be necessary. Real property transactions and utility relocations may be necessary in support of this project. 3.
