With our first major winter storm, it is a good day to talk about flooding. This is not a problem limited to Marin, but is a possibility wherever people live near water. Where I grew up, in Trenton, New Jersey, the major streams had been buried and diverted since the 18^th century. When the rain was heavy and the Delaware River filled, buildings flooded.

In Marin, heavy rains and runoff into our creeks can cause flooding in nearby neighborhoods. If the bay tides are high, the streams drain slower and flooding can be more severe. There have been only a few years of flooding in Marin. The Marin Sheriff’s Department has a short history. 1982 was probably the worst year, with 2005-06 next in severity.

I lived on the Arroyo Holon Creek (Baltimore Canyon) in Larkspur in 1982 when we had much rain and high tides. The house was on a beautiful sunny lot with redwoods and oaks and a bridge across the creek. Close to midnight, the water came up to my front doorstep, flooding the garden and basement. My electrical sump pump in the crawl space could not keep up, and then the power went out. Winds that often accompany winter rains had taken out a power line. The furnace was under the house. One cold night!
