The City of Tehachapi sponsers a key feature: The Double Arch Culvert

Flood control and erosion mitigation is our primary concern along Antelope Run. Currently, even a 10% event would flood Highway 202. rendering it impassable. A 100-year flood would devastate the area. The City of Tehachapi has already removed the undersized culverts at the Valley Blvd. Route 202 crossing and installing a bridge built above two large box structures equipped to handle the 3,000c.f.s that a 1% event would bring.

With DWR funds we will also be able to diffuse the water upstream with a series of drop structures combined with brush layering and geo-textile fabric installation along the banks. The structures will flatten the slope and reduce flow speed, mitigating erosion. Selected shrubs will be native to the area and contain binding roots that help stabilize stream banks. The drop structures will be built from native rock and designed to mimic naturally occurring geologic formations. In addition, approximately 2,000 cubic yards of earth will be imported and used to offset erosion effects. Stream debris clearance is another important piece of our flood control and erosion mitigation efforts. The Tehachapi Resource Conservation District (TRCD) will administer an Adopt-a-Stream program with awarded grant monies. This program will utilize volunteers from the community to join forces and remove debris that is dumped into Antelope Run. There will be an educational arm of this program, as well, that raises awareness about illegal dumping and encourages citizens to consider the survival of surrounding ecosystems rather than indulge in destructive dumping practices.
