Degraded Channel and Riparian Areas
Degraded Channel Structure and Complexity
Project consists of an Integrated Stormwater Treatment Facility designed for habitat and water quality benefits and in-stream enhancement . Includes:
• Diverting stormwater from industrial land uses to constructed channels, ponds, wetlands, and permeable berms for treatment (through detention, infiltration, & filtration)
• Grading areas adjacent to Carli Creek to create off-channel and floodplain habitat
• Removing non-native and invasive vegetation and planting native species
• Adding large woody debris and beaver-attraction structures to the Carli Creek channel
Estimated total cost includes land acquisition.
