Existing Evacuation Routes

---

 The main evacuation route for the Del Puerto Canyon area is Del Puerto Canyon Road (CA 130) which crosses into Santa Clara County and evacuation zones SCC-209 and SCC-208. This road, with two lanes and paved surface, is maintained by Stanislaus County within its own boundaries. It connects to Diablo Canyon Parkway near Interstate 5 and stretches about twenty-five miles westward across the mountains of the Coast Range until it intersects with Mines Road in Santa Clara County. From there, Mines Road offers access to the south toward San Jose or to the north, eventually reaching the city of Livermore. 

There is only one paved road leading out of the Diablo Grande community, Diablo Grande Parkway. This road, with two lanes and a paved surface, extends for 8.5 miles from the development, linking up with Del Puerto Canyon Road at Interstate 5, where it transitions into Sperry Road. As an alternative route, evacuees can take Diablo Grande Parkway for approximately 3.5 miles from the entrance gate to Oak Flat Road. Oak Flat Road then extends eastward for 2.6 miles before meeting Ward Road, which heads north toward the city of Patterson.
