DESIGN DEVELOPMENT
Project Goals 1. Protect Public Health • Protect sewer crossing and manhole from stream forces • Protect private property from erosion and flooding • Treat stormwater from existing industrial outfalls 2. Restore Johnson Creek • Enhance stream process, reconnect floodplains and increase stream complexity within project area • Improve fish and macro invertebrate habitat • Add high flow refuge and improve fish passage 3. Protect Natural Areas • Remove nonnative vegetation & enhance the riparian corridor 4. Create a Community Resource • Integrate park and natural area developments together • Provide community educational opportunities

Summer 2016 – BES Monitoring
DSL Years 1 and 2 Monitoring by BES
DSL Years 1 and 2 Monitoring by BES Instream Habitat Assessment Summary Overall, the Luther Road habitat restoration project should be deemed a success . The condition of habitat in the reach prior to the project was poor, but it is now on a trajectory toward very high quality . The abundance and distribution of pool habitat in the reach is a major asset. Three backwater pools were mapped this year. These habitats are highly valuable year-round, as they provide low energy areas for fish to feed and rest. Greater quantities of wood within the pools will provide the needed cover habitat while creating the hydraulic energy necessary to moves sediment out of the pools and maintain pool depth.
Geomorphic Monitoring
Geomorphic Monitoring Sediment Mass Balance The mass balance analysis produced a net fill in the project area of 1,135 cubic yards of sediment. This material, which represents approximately 20% of the total volume of aggraded material in the project area, must have come from upstream reaches. Key Adaptive Management Areas 1. Protection of the sewer Interceptor crossing, 2. Grade control at the upstream end of Reach C to protect against the potential for headcut migration, and 3. Right bank stabilization along the avulsed channel to protect the overlook structure.
