Cornerstone Litigation

On April 7, 2017, Advocates for the Environment filed a lawsuit on behalf of a local citizen's group against the City of Agoura Hills, challenging its approval of the Cornerstone Project near the intersection of Agoura Road and Cornell Road in the City of Agoura Hills. The petition is online.

Cornerstone Project

An out-of-state developer wants to construct 35 dwelling units and almost 70,000 square feet of commercial space and over 100,000 square feet of parking lot on a parcel at the corner of Agoura Road and Cornell Road in the City of Agoura Hills. The land is currently vegetated with native sage scrub and coastal oak wildlands. The site, which Los Angeles County designated as part of a Significant Ecological Area before it was annexed into Agoura Hills, hosts 59 oak trees. Twenty-nine of these would be removed for the project, and the remainder would be encroached upon to the point where their long-term survival is questionable.

The City of Agoura Hills gave final approval to the project on March 8, 2017, and Advocates for the Environment filed a lawsuit against the project on April 7, 2017, representing a local citizen's group named Save the Agoura Cornell Knoll (STACK).

Violations of CEQA

The City of Agoura Hills prepared only a CEQA Mitigated Negative Declaration (MND) for the project, although it will have several potentially significant environmental effects. Under the California Environmental Quality Act (CEQA), the presence of these significant effects means a full Environmental Impact Report (EIR) is required.

Potentially significant environmental effects include:

Mitigation measures are vague, deferred, unenforceable, or ineffective, another CEQA violation.

Planning and Zoning Law Violations

California state law requires projects to be consistent with local land-use plans, including the general plan and any relevant specific plans, but the Cornerstone Project is inconsistent with the local plans in several important ways, including the following:
