Green Valley Creek High Flow Channel Project

Green Valley Creek High Flow Channel Project

Green Valley Creek flooding of Green Valley Rd and adjacent property has increased in magnitude, frequency, and duration from recent accumulation of sediment. The purpose of this project is to lessen recurrent flooding of Green Valley Rd by improving storm flow capacity within the section of Green Valley Creek at the Green Valley Rd crossing. The project would include understory vegetation clearing, placement of temporary fill for an access ramp, excavating and maintaining channels for a period of five years, and re-vegetation of the project area with native plants. Although there would be temporary disturbance to wildlife and their habitats, there would be long-term benefits including increased aquatic habitat, riparian restoration, fewer strandings due to flooding, and reduced degradation of habitats downstream from sedimentation.
