Answer
I do not know enough about the soils in that part of Calif. to answer this question. And it sounds like some one needs to look at your situation on the ground so I suggest you contact the Calif. State Forestry agency and ask one of their Forstrs to come out and assist you --this is a free service in most states. Here is a web link to the directory of Foresters with the Calif. State agency. They are listed by County so you can select the Forester nearest you.  http://www.fire.ca.gov/php/rsrc-mgt_content/downloads/20005_06ForestAdvisorlist....
