Tell Your Supervisors--Vote NO on Stream Ordinance

San Geronimo Valley homeowners ask: Can we stop the stream ordinance demanded by SPAWN? Can we protect our homes? Will County officials listen to our concerns?

Actions you can take now:

1. By Wednesday July 13, send your personal emails to County 
DRodoni@marincounty.org BOS@marincounty.org TLai@marincounty.org KDrumm@marincounty.org

Subject line should refer to July 19 BOS meeting and San Geronimo Stream Ordinance.
 Ask all 5 Supervisors to vote NO on the stream ordinance.
Describe your home (but do not give your street address). How long have you lived in the Valley? What are your concerns about rules applied to your house? County officials will read specific complaints from individual homeowners, but pay less attention to standard form mass mailers.

2.  Tuesday July 19 attend Supervisors meeting on Zoom or in person.  Each person has the right to speak for 2 minutes. It is better to speak in person, if you have time to car pool to Civic Center. Find Zoom instructions at  https://www.marincounty.org/depts/bs/meeting-archive

3.  Visit San Geronimo Valley Stewards website and read the ordinance summary.  www.sgvstewards.com    

  • On October 11, 2022 the stream rules will take effect and govern your property:
  • • All development will be restricted for 100 feet on both sides of any stream, including ephemeral flows that appear only during rain.  
  • • County will require $2,000 to $3,000 in permit fees and environmental reviews.

Don't Give Fire the Final Vote

This article is submitted by Jim Barnes, a Director of San Geronimo Valley Stewards. Jim is a lifelong resident of San Geronimo Valley, with 30 years experience flying air tanker planes over fires in California and the western U.S.

On July 19, Marin Board of Supervisors will vote on the new stream ordinance for San Geronimo Valley. SPAWN demands the ordinance as settlement of its lawsuit to protect salmon.  SPAWN rules would violate common sense management of our fire prone landscape and end in tragedy.
