​“This is truly the best possible outcome,” said Sierra Club’s counsel Josh Chatten-Brown. “And the pivotal factor was the successful litigation by the Sierra Club and its partners, compelling the sellers to become willing participants in the permanent preservation of Proctor Valley’s crucial habitat for endangered and threatened wildlife.”
​
Proctor Valley is vital to the survival of endangered species such as the California gnatcatcher, San Diego fairy shrimp, Otay tarplant, San Diego button celery, golden eagle, and Quino checkerspot butterfly, among others.

​Represented by Chatten-Brown Law Group, PQ-NE Action Group entered into a settlement agreement with Lennar Homes to settle litigation concerning the Junipers, a housing project in Rancho Peñasquitos.  Construction on the project was halted in February 2023 after the Superior Court ruled in favor PQ-NE Action Group, finding violations of CEQA in the project’s environmental review.
