Governments virtually everywhere move at a glacial pace. Even so, none of the projects high on the wish list of this bill are planned for Los Angeles. They're primarily about expanding dams and improving stormwater capture, the latter's big project being in the Sacramento Valley, hundreds of miles north of LA.
I'm not a government or public services apologist by any means, but these fires are a natural disaster. It's not the fire department's fault that 80-100 mph winds push fires through hills and canyons. They're fire fighters, not miracle workers.
The FD can't prevent residents from the mostly ineffective (but emotionally understandable) strategy of hosing down their properties when they see flames. Unfortunately that action further reduces water availability to FDs.
The Delta Smelt controversy, which I'm not well-versed about, is a northern California agrucultural and urban water issue, and has little to do with firefighting water in So Cal. It's roughly akin to someone in Charlotte, NC, saying if only more water were available in Pittsburgh, PA, then Charlotte wouldn't be dealing with drought conditions.
