On a drizzly Thursday in April, dozens gathered beside a weedy San Jose shoreline to break ground on four miles of new levee and 2,900 acres of restored habitats, a future buffer from the rising Bay.
With rains overwhelming local drains in late October, the visible construction progress over the summer on Orange Memorial Park, a regional stormwater capture facility in South San Francisco, seems timely.
To help keep Highway 37 open despite heavy storms and rising tides, planners are assessing a wide range of options from elevating the road to rerouting it. But zeroing in on the right redesign may be trickier than anticipated. New research shows that, with sea level rise, protections for this troubled North Bay road can worsen flooding and economic damages as far away as the South Bay. The good news is that this work can also identify Highway 37 redesigns that avoid these catastrophic impacts.
What do rock walls across Delta water channels, brown lawns, bans on hoses, and red flag fire warnings have in common? California’s deepening drought. Up in the Delta, the state is once again piling up rocks in False River to prevent salty ocean tides from intruding too far inland, and too close to intakes for the state’s water supply pumps (there’s no enough pushback from snowmelt and river outflow this year to keep things fresh!) Meanwhile, many water districts around the Bay Area have already called on their customers to reduce their water use by 10-25%, with Marin going first in April.
