History of Corte Madera Creek
On Tuesday evening, April 19th, 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.
