Lancaster FAQ
Where is the nearest cooling center?
Call 211 or check ready.lacounty.gov when a heat alert is active. Most county libraries, senior centers, and parks community rooms participate. Many offer extended evening hours during multi-day heat events with free water and transport.
Does the county pay for tree planting on my street?
TreePeople and LA County Forestry Division partner on free street-tree plantings in Heat Equity Zones, including delivery, hole-digging, and 3-year establishment care. Outside those zones, owners typically arrange and pay for parkway plantings themselves.
Los Angeles FAQ
Where do I find a cooling center?
Call 211 LA County or check the Emergency Management Department website during heat advisories. Libraries, recreation centers, and senior centers serve as cooling sites with extended hours during declared events.
Can I get a free shade tree?
City Plants distributes free shade trees to LA residents and businesses with planting commitments. Apply online; staff confirm parkway eligibility and species selection per Bureau of Street Services Urban Forestry standards.
Are landlords required to provide AC?
Not currently. LA tenant-protection rules require habitability under LAMC §161, but no cooling mandate exists. AB-1648 and proposed local ordinances are under discussion for future maximum-temperature standards.
