Preserve Lamorinda Open Space


The Moraga Town Council will soon decide whether to approve or deny this damaging project. On Wednesday, November 14, the Council will hold a public hearing at, 7:00 pm at Joaquin Moraga Intermediate School 1010 Camino Pablo. Town of Moraga Planning Staff is recommending its denial, citing multiple inconsistencies with the Moraga General Plan. (Read the staff report for the upcoming Town Council meeting here)

On October 18, 2018, the Moraga Planning Commission voted 4-2 to recommend the project’s denial to the Town Council. The Commission also unanimously recommended that the Council consider a smaller project at a density of 1 unit/5 acres, provided such a project could be made consistent with the General Plan and that access constraints could be resolved.

Please come to the hearing! A good turnout sends a strong signal to the Council that the community really cares about this issue. Even if you don’t wish to speak, please attend the hearing if you can. Emails/letters are also extremely helpful. For more information on project impacts and how to write a letter click here .


In Spring of 2013 the Town of Moraga circulated a Draft Environmental Impact Report (DEIR) for the proposed “Bollinger Valley” development on 186 acres of open space in Moraga adjacent to Las Trampas Regional Wilderness.

The Town received a large volume of comments from concerned residents as well as a detailed legal and technical analysis by PLOS. Since then, we’ve awaited a Final Environmental Impact Report (FEIR) which responds to those comments. It is now available for review here.

Based on information provided in the FEIR, the proposal currently consists of 85 houses. If built, this development would add over 800 daily car trips to Lamorinda’s roads, bulldoze an astonishing 1.8 million cubic yards of soil, and cut down more than 200 mature native trees. Access to the development would be via St. Mary’s Rd. to Bollinger Canyon Rd. to Valley Hill Dr. Valley Hill Dr. is currently a one-lane country road and would require widening, re-engineering, and significant tree cutting to accommodate the traffic.

Precious habitat for raptors and songbirds, foxes, coyotes, deer, and bobcats, as well as threatened species such as the California red-legged frog and Alameda whipsnake, would be destroyed by this project. Public views from East Bay Regional Park trails in and around the Las Trampas Regional Wilderness area would also be negatively impacted.

The Town Council must decide whether or not to approve this project. Please write to the Council to share your views. For more details on project impacts and letter writing information click here.
