(Road Funds) (District II) [CDD-CP# 06-37] Project No. 0672-6U2535 DATE: May 22, 2007 PAGE: 2 of 2 FISCAL IMPACT: There is no impact to the County General Fund. This project is funded by Road Funds. REASONS FOR RECOMMENDATIONS AND BACKGROUND: The project consists of constructing a 50 foot long, 60"RCP culvert underneath Carquinez Scenic Drive (approximately 50 feet west of the intersection of McEwen Road and Carquinez Drive) to replace an existing culvert crossing that has become silted in. Currently the present culvert (an 8'X8' box culvert) has silted in due to an excessive amount of silt and debris that has entered the culvert from upstream(including illegally dumped debris). The current culvert will be abandoned, because of the significant environmental impacts that desilting would cause. The new culvert will be placed on top of the present box culvert to correct the grade of the drainage and will be placed approximately 12 feet below the existing crown of the road. It will be necessary to remove eleven trees: 5 Bays (Umbellularia Californica), 4 Pacific Willows (Salix Lasiandra) and 1 Coast Live Oak(Quercus Argrfolia), some brush and a Pacific Willow tree stump. However, the project area is densely vegetated and removal of these trees is not expected to alter the scenic quality of the surrounding area. A dewatering system may be necessary during construction and any flowing water will be diverted around the project site. The system will be designed to ensure that flow downstream of the construction is maintained at all times during construction if necessary. Any wildlife encountered will be lawfully relocated downstream. The project is located in West County and will not result in the removal of any scenic resource. CONSEQUENCES OF NEGATIVE ACTION: Delay in approving the project will result in a delay of design and construction. i CONTRA PUBLIC WORKS DEPARTMENT COSTA INITIAL STUDY COUNTY OF ENVIRONMENTAL SIGNIFICANCE PROJECT# 0672-6U-2535 CP# 06-37 PROJECT NAME: Carquinez Scenic Drive Culvert Project PREPARED BY: Kimani Birden V?
