Document Description
Flood channel maintenance along Adobe Creek in Petaluma. Work in the Sartori Reach will include demolition of an existing grouted rock check structure and replacement with a rock step pool structure; installation of planted rock rip-rap for bank stabilization at a slip-out along about 40 feet of stream frontage; excavation of about 700 cubic yards of accumulated; and vegetation management throughout the reach. Vegetation management will include selective removal, thinning, and pruning of vegetation within the stream channel, and will focus on invasives such as blackberry and on trees, primarily arroyo willow, growing in the channel bottom and blocking the flow. A goal of vegetation management will be encourage the development of overstory vegetation to shade the stream. Work in the McDowell Reach primarily involves removal of sediment from the existing sediment detention basin near the McDowell Boulevard Bridge in an area approximately 250 feet long and 80 feet wide. Work will be done with a long-reach excavator operating from the top of bank. Vegetation management along the entire McDowell Reach will be as described for the Sartori Reach. The California Department of Fish and Game is executing a Lake and Streambed Alteration Agreement number 1600-2006-0331-3 pursuant to Section 1602 of the Fish and Game Code to the project operator, Sonoma County Water Agency.
