After moving to Chatsworth 34 years ago, Diana and Phil barely had the boxes unpacked when she laced her shoes and jumped into community projects. Diana attended meetings with her rolling crate filled with binders, notes, and reports piled high. At community presentations and meetings her scientific mind was in high gear whether asking important questions or challenging a statement she felt wasn't based on facts. She coupled her astute mind with her compassionate feelings for women, children, and the environment. Diana's spirit touched many and we are all fortunate for Diana's giving us so much of herself to make our world a better place to live.

 In memory of Diana Dixon-Davis by Teena Takata, SSMPA President:

I always think of Diana, first, as Passionate - 

Unwavering; absolute courage in all her opinions, and always willing to express her position; it didn't matter, ever, if it was the popular position or the less-favored position. There was no question what Diana's position on any matter was.

A tireless worker for the community, she spent an incredible number of hours working for the SSMPA, the PTA, the Chatsworth Neighborhood Council, the SSFL CAG, the Chatsworth Community Coordinating Council, and always treasured the local state park the community helped create with its activism. She loved sharing origami with the children and working with them, and also spent many hours behind the scenes, helping groups out as treasurer and using her educational background in demographics from Berkeley as appropriate to evaluate various community issues, for the great benefit of the community.

We are sure Phil, her children, and other family members will sorely miss her. But the community also has lost an incredible advocate for open space and educating young members of our community to appreciate the outdoors and their education.

Rest in peace Diana, we will be missing you.

 The July 15th, 2014 meeting of the Los Angeles County Board of Supervisors was adjourned in memory of Diana Dixon-Davis at the requests of Supervisor Antonovich and Supervisor Yaroslavsky.

From  NASA's Comparative Analysis  of

Background versus Risk-based Cleanup Scenarios

for the Soils at Santa Susana Field Laboratory

"The more aggressive cleanup of the site that would occur under the background cleanup (more soil removal, more trucks entering the site, more emissions, more road miles, more soil to dispose of in landfills, etc.) could result in an increase in traffic accidents and spills and more habitat modification, as well as disturbance of wildlife and more impacts to archeological resources, all of which might result in reduced net benefits when compared to the risk‐based cleanup scenario." p. 5-1  

SSMPA calls for SSFL Cleanup target date to be pushed back. 


SSMPA's mission is to preserve and protect the Simi Hills, Santa Susana Mountains, and regional open space.
