California's state wildlife and transportation departments signed a credit agreement on an innovative pilot project to create advanced mitigation credits for wildlife highway crossings. The mitigation crediting system developed for the Laurel Curve Wildlife Habitat Connectivity Project on Highway 17 in Santa Cruz County can be used to transition into a statewide program being developed through the new Regional Conservation Investments Strategies Program.
Using the Laurel Curve project as a pilot, the California Department of Fish and Wildlife (CDFW) and the California Department of Transportation (Caltrans) developed a model compensatory mitigation crediting system.
An agreement between CDFW and Caltrans creates credits that can be used to mitigate for impacts to wildlife movement for future transportation projects within a geographical area defined as the Service Area, and determines the price of each credit. Mitigation credits are calculated using a first-of-its-kind methodology which takes into account the length of highway to be improved in lane miles or the project footprint in acres and the total cost of the project. When appropriate, Caltrans may sell or transfer the credits within Caltrans or to other transportation agencies with projects in the Service Area, thereby freeing funds for additional infrastructure projects.
"Highway 17 bisects undeveloped, wildlife-rich land in the Santa Cruz Mountains, and for the safety of deer, mountain lion, and motorists, too, we need to connect this habitat with a safe corridor. CDFW, Caltrans and the new transportation package have come together to solve this problem.".
Senate Bill 1, the transportation funding package, includes $30 million for advanced mitigation strategies for projects similar to the creative Highway 17 project.
"Not only will this improve wildlife habitat connectivity and highway safety, but will also allow us to expedite future transportation projects using the mitigation credits made available."
CDFW and Caltrans worked closely with the California Transportation Commission (CTC) to formulate the credit agreement. Caltrans, CDFW, the Land Trust of Santa Cruz County, Pathways for Wildlife, the U.C. Santa Cruz Puma Study and the Santa Cruz County Transportation Commission all worked together to develop a solution for the wildlife crossing at Laurel Curve.
Caltrans has built similar wildlife crossings on highways 1, 68, 101, 152 and 280.
