The Puente Hills Landfill Native Habitat Preservation Authority manages almost 4,000 acres of land in southern Los Angeles County. This landmass, combined with other publicly protected lands in the Puente-Chino Hills area, is a biodiversity hotspot for a number of flora and fauna, even though it is less than 30 minutes by car from downtown L.A. The land of the Habitat Authority is bisected by Harbor Boulevard, a 4-lane road that carries approximately 30,000 vehicles per day at speeds of up to 50 MPH (Gullo 2006). A study by researchers at California State University-Fullerton found that the incidence of road kill on Harbor Boulevard was very high relative to a larger study area (Elliott & Stapp 2007). Surveyed road kills have included coyotes, bobcats, and American badgers. A wildlife underpass was constructed in 2006 to mitigate wildlife mortality due to vehicles on the corridor.
The underpass received a $901,000 TE grant through the MTA award process and an additional $337,000 in TE funds from the statewide pool.
