DESCRIPTION
This is Phase 3 Restoration Design of the Valley Creek Restoration project. Phase 3 included the restoration design of a channelized and culverted portion of Valley Creek into a lengthened, remeandered channel combined with fishway passage structures installed within reduced remaining culverted length. This Round 10 SRFB project completed the design and permitting components of Phase 3, such that the project can be promptly initiated when capital funding is secured. This design project took the conceptual (30%) design to 100% construction-ready plans that includes complete permitting document. This design work answered questions such as stormwater segregation and handling and fishway grating design.
The concept of fishway inserts was modified to use baffles inserted into the culvert at regular intervals rather than using 4 individual inserted structures.
Phase 3 Objectives: Fish habitat and passage, biological processes, riparian restoration, wetland and floodplain enhancement, channel conditions.
Phase 3 Design Objectives: 100% design drawing package, including specs. and completion of all permitting and project reviews
