Rancho Cañada Floodplain Restoration Project Construction Management (Phases 2 and 3)

Description

The Rancho Cañada Floodplain Restoration Project (Project) is located on the former Rancho Cañada Golf Club property in the Rancho Cañada unit of the Palo Corona Regional Park, Monterey County, California, along the Carmel River. The project site is approximately 185 acres in size and spans both banks of the Carmel River. The Monterey Peninsula Regional Park District (MPRPD, Owner) maintains the former Rancho Cañada Golf Club clubhouse on the property as its offices, and the facility also functions as a visitor’s center and trailhead for the public’s access to the remainder of the 4,350-acre Palo Corona Regional Park to the south. Immediately downstream of MPRPD’s property is the remainder of the former Rancho Cañada Golf Club property, which is now the 60-acre Rancho Cañada Village (RCV) property, a proposed residential development.The Project is focused on restoring a 1-mile section of Carmel River so that natural geomorphic processes will reconnect the river with historic floodplain habitat and create a mosaic of self-sustaining riparian habitat types and instream complexity to benefit juvenile and adult steelhead and other aquatic riparian species. The project area currently serves as a public park and certain amenities/infrastructure are critical for it to continue to function this way.To accomplish the overall goal of the project, the project will remove riprap wherever it is not protecting key infrastructure, recreate historical channel and floodplain features, widen the channel to increase habitat, and add alcoves for backwater habitats. Approximately 40-acres of connected floodplains will be created. These new floodplains will be revegetated with native plants and will require an irrigation system to be constructed, maintained, and disposed of at the end of the planting establishment period. The irrigation system will include replacement of the driving range well pump. Existing lar
