Title

Alamo Creek Bank Stabilization and Flood Management Pilot Project

Description

The main purpose of this Project is to implement an ecologically uplifting approach to flood management that will reduce erosion, restore aquatic and riparian habitat, and promote public recreation. This project will also serve as a pilot project for wider use throughout Zone 7's system. The Project includes combinations of habitat uplift and bank stabilization features, collectively referred to as ‘modules.’ Module designs will direct flows to the center of the channel and away from the banks and revegetate the banks with native plant species. The Project will reduce bank erosion caused by high turbulence and flows down Alamo Creek, thereby enhancing flood protection by maintaining the flood control channel. Reduced toe scour and bank erosion will also reduce fine sediment inputs to the creek and improve downstream water quality. The Project goals are: 1. Erosion Reduction a. Decrease risk of catastrophic bank failure b. Reduce toe erosion and degrading water quality downstream 2. Aquatic & Riparian Habitat Restoration a. Restore native planting within channel b. Preserve channel grades for better migratory fish access 3. Public Recreation a. Uplift the aesthetics of the creek channel b. Promote public engagement with restored channel
