Lot 25
Protecting a Missing Link in Mt. Diablo Creek
Size: 5 acres
Location: Marsh Creek- Morgan Territory area

Save Mount Diablo's Lot 25

After ten years of work we have just protected a significant missing link of Mt. Diablo Creek. Beginning in 2003 we worked with the City of Clayton on a development project: 24 lot Diablo Pointe. A remaining parcel,“Lot 25” is 5 acres including a section of creek. Its preservation is important and precedent setting in several ways.

During the development planning process, we focused on protection of the creek corridor, oak woodland and a canyon along the eastern boundary as well as buffers to the State Park on the east and south. The most significant precedent in the agreement with the developer was that a caretaker house along the creek was to be removed and the riparian corridor replanted.

Marsh Creek VIIOn Dec. 21, 2004 the redesigned Diablo Pointe project was approved. When the developer asked the State Park to accept Lot 25 in 2011, the Park rejected the offer due to budget cuts. We then worked with the developer and the City to transfer the property to Save Mount Diablo for preservation. We will take care of the property until the State Park is able to accept it and make it part of the Park.

The property has a high quality, incised rock bottom, 500 feet of Mt. Diablo Creek with intact riparian vegetation including maple, cottonwood, sycamore, oak, buckeye, and willow trees. It’s lovely and overgrown, shifting between pools of water and rocky ripples. The old house site and flat area along the creek are now studded with straight lines of plastic tubes protecting 150 live and valley oak trees planted to restore the corridor. Our volunteer stewards will care for the trees and do additional restoration.
