What's Happening Now

Low Impact Development (LID)

Low Impact Development practices such as rain gardens, vegetated roadside and medial strips, impervious surface area reduction, and rain barrels slow down storm runoff, improve storm water quality and can reduce flooding from small storms we see each year and complement efforts at reducing the damage from infrequent, large scale flooding. For more information on the County's LID requirements and recommendations, please see the LID manual here.

Scroll down to the bottom of our Landowner Resource page on this website for great information on rainwater catchment, infiltration, water conservation, and more.

History of Corte Madera Creek

On Tuesday evening, April 19, 2011, the Flood Zone 9 Advisory Board sponsored a presentation on the History of Corte Madera Creek by Ms. Laurel Collins, a fluvial geomorphologist and a Marin native. In an interesting and clever presentation, Ms. Collins used historic maps overlaying modern maps and newspaper articles from the mid-1800s to show the evolution of the creek system we call Corte Madera Creek.

Creek Bank Erosion

Erosion is usually the cause of most creek bank failures. Finding the cause of the erosion is essential to developing an effective solution. Erosion is caused by water from three possible sources. Check out this information on our MCSTOPPP web page.
