This Project is a component of the Vineyard Springs Comprehensive Plan (VSCP) Drainage Master Plan (DMP). The Project is located on vacant land west of Wildhawk West Drive, south of Larry Gury Community Park, and north of Laguna Creek in the Vineyard Spring community of unincorporated Sacramento County.
During large storm events, water spills out of Laguna Creek and travels north across the land to Gerber Creek in what is known as the inter-basin transfer. This inter-basin transfer is a shallow floodplain with a depth of two feet (2’), represented by a Federal Emergency Management Agency (FEMA) Special Flood Hazard Area (SFHA) Zone AO. The DMP identifies this Project’s flood control basin as one of the major improvements needed to stop this inter-basin transfer. The Project improvements are the first step needed to remove the FEMA SFHA Zone AO floodplain, removing flood risk to the properties within the inter-basin transfer area, and ultimately allowing the affected area to be developed.
During large storm events, the proposed detention basin will temporarily store community stormwater runoff until it can be conveyed to Laguna Creek. Most of the time, the basin will be dry and available for use as soccer and play fields. Upon completion of the Project, Southgate Recreation & Park District (SRPD) will construct and maintain the soccer and play fields, irrigated turf, landscaping, trail lighting, and associated amenities.
The Project will construct a 15-acre multi-use detention basin requiring the excavation of approximately 117,000 cubic yards of soil. In compliance with the DMP, approximately 45,000 cubic yards will be placed immediately west of the basin on two private properties. The awarding contractor will off haul the remaining 72,000 cubic yards of soil to a permitted site. It is important to note that the off haul will involve the use of many dump trucks traveling on Carmencita Avenue throughout the day for several weeks.
The Project will also install an armored concrete weir, culverts, paved multi-use trail and utilities, fencing, and internal basin/field/trail utility infrastructure. SRPD will install the soccer/play field landscaping, and other associated public use facilities/amenities, within the basin and around the trail as a part of a separate project in the near future.
The Project is scheduled to go to the Board of Supervisors for approval to advertise for construction contractors on April 6, 2021. A second newsletter will be mailed out to provide an update after the project is awarded to a contractor. That newsletter will provide additional contact information for the construction phase of the project.
