Summary of New Stream Rules for Homeowners

Here are the new dates for Marin County's consideration of the proposed Stream Conservation Area Ordinance:

Monday November 8: Workshop with Planning Commission and Community.

We offer this summary of how the new stream rules proposed by Marin County may effect your property and house. We believe the ordinance and exhibits will burden families with costs and delays for ordinary home maintenance and improvements. The rules are confusing and will require homeowners to consult lawyers and pay experts for common projects.

In San Geronimo Valley, 4200 people live in a forest surrounded by dry grassland. The new stream rules discourage sensible vegetation management, and do not require compliance with state law and local fire agencies regarding defensible space and fire prevention.

The SGV Stewards and supporters are not professional developers building new mansions. We are the 2,000 families who live in existing homes, many built decades ago, on small lots close to creeks.

The new stream rules apply to only the San Geronimo Valley. Marin County does not burden any other area with these new costs and delays.


A. Where to read the new stream rules: This is a brief summary. You can read the exact language of the new rules by going to the Marin County website: www.marincounty.org/sca

Scroll down to "2021 SCA Ordinance Documents" Exhibit A is the Stream Conservation Area Ordinance (SCAO). Supporting Resource Materials include: Exhibit C on Site Assessment Exhibit D Standard Management Practices (SMP's)

B. Your comments are welcome: Please send your questions, objections, and recommendations to the public officials we list at the end of this email.

We hope you will participate in the Monday November 8 workshop for the community and the County Planning Commission. Watch your emails for exact time and details how to log onto the virtual meeting. The Planning Commission is scheduled to vote Monday December 13.

C. New Stream Rules: Do you want to: replace your wood deck, repair your roof shingles, or add 400 square feet to your home, or pave your dirt driveway, or build a tool shed, or install solar panels?
