Stream Conservation Area Ordinance(SCAO)

Marin County moves forward with a new Stream Conservation Area Ordinance (SCAO). The County calendared: Sept 7 release of draft ordinance and begin public comments; October 25 Planning Commission hearing; December 7 Board of Supervisors hearing.

SGVStewards leadership is participating in meetings with Marin County staff and a professional facilitator hired by the County. We are reviewing a tentative non-public draft of the proposed ordinance and other materials.

We are particularly concerned about fire prevention and defensible space around homes. One goal should be maintaining our mature oak trees and redwoods, while thinning fire-prone shrubs and separating tree canopies that spread wildlfire.

We are also exploring government assistance for the various reports and certifications that the new ordinance will require for ordinary home repairs and improvements.
