Caitlin Shanley Blog, Newsletter, Stormwater

When a storm event sweeps in across the Pah Rah Mountain Range in Northwestern Nevada, rain washes down from the 8,247’ summit and finds its way to the intersection of Prater Way and Vista Boulevard in the City of Sparks. The area soon floods and causes undo traffic problems for the community and its residents. Twenty-five years ago the problems were more severe. On New Year’s Day 1997 a massive rainfall swept through Northern Nevada and Northern California causing $700 million worth of damage. The Truckee River took out schools, businesses, and anything in its way as it surged across …

It’s no secret that in recent decades California’s climate has grown more extreme. Epic droughts, raging wildfires, and—when it does rain—heavier storms often inundate the state year round. While the impact and response to such newsworthy events is front and center, countless other weather related situations are playing out behind the scenes. In El Granada, California, just south of San Francisco, heavy rain events were overwhelming the Portola Pumping Station, leading to sanitary sewer overflows in the environmentally rich area in and around Half Moon Bay. The Sewer Authority Mid-Coastside (SAM), which serves the communities of Montara, Moss Beach, and …

When it comes to talking trash in California, it goes beyond just players messing with one another on and off court. Sometimes the trash talk happens in court. In the late 1990s the Los Angeles River was jammed with so much trash it was spilling into the Pacific Ocean. Leveraging the Total Maximum Daily Loads (TMDL) tool cited in the Clean Water Act, the California State Water Resources Control Board developed a Trash TMDL set at zero for the Los Angeles River Watershed. Backed by the Environmental Protection Agency, the TMDL could be applied countywide. Twenty-two cities sued to stop …
