Important new work that will help shape LA's approach to bringing more shade to neighborhoods as a legacy of the mega-event era.
Hot off the presses 🔥 We have a new report on how the City and County of L.A. can strengthen their responses to extreme heat. We look at ways to reimagine and remake the outdoor urban environment to reduce risks to vulnerable communities.

Great piece about why Zone Zero rulemaking is complicated for a state as big and diverse as CA. Thanks @nohaggerty.bsky.social for the clarity, and to the many (mostly) SoCal voices of reason including Max Moritz @ucanr.edu for improving the outcomes.

How Zone Zero, designed to protect California homes from wildfire, became plagued with controversy and delays
California needs new rules to help future wildfires from destroying homes and businesses. But Zone Zero regulations, a key tenet of the state's plans, have roiled homeowners.

Finally some good news for LA and Eastern Sierra ecology and communities we rely upon
A major shift in where L.A. gets water: The city will double the size of a project to transform wastewater into purified drinking water, producing enough for 500,000 people. The recycled water will allow L.A. to stop taking water from creeks that feed Mono Lake. www.latimes.com/environment/...
Los Angeles will nearly double recycled water for 500,000 residents
