Urge Local Leaders to Support Cleaner Heating and Cooling
Cities and counties across California have a clear opportunity to improve air quality, fight climate change, and save residents money by adopting building code provisions that encourage or require new air conditioner replacements to be capable of both cooling and heating. These policies -- often called AC-to-Heat Pump reach codes -- ensure that when an air conditioner is replaced, or installed for the first time, in a single-family home, duplex, townhome, or commercial buildings with rooftop packaged units, it is a two-way air conditioner, also known as a heat pump. Right now, you can urge your city to make sure the next air conditioner installed in homes is a heat pump, a system that cools and heats efficiently.

POST Purchases Ranch Above Coyote Valley, Linking Nearly 50,000 Acres of Protected Land
Congratulations to Peninsula Open Space Trust (POST) for their purchase of Mead Ranch, securing nearly 2,000 acres in the Coyote Valley area! Coyote Valley has long been a conservation priority area for the Loma Prieta Chapter, and hence for our statewide 30x30 campaign, so we do all we can to support efforts to protect open space in and around Coyote Valley.
"The Santa Clara Valley Bird Alliance, the Sierra Club Loma Prieta Chapter and the American Bird Conservancy support adoption of the Draft Bird-Friendly Design Ordinance adding Section 18.40.280 to the Palo Alto Municipal Code as proposed in Attachment A.

Heritage Oaks Memorial Park Draft Supplemental Environmental Impact Report
"The Santa Clara Valley Bird Alliance and the Sierra Club Loma Prieta Chapter are environmental organizations with deep commitment to the natural landscapes, wildlife, and environmental resources of Santa Clara County. We submit the following comments on the Heritage Oaks Memorial Park Draft Supplemental Environmental Impact Report (DSEIR). Our comments are in addition to comments already submitted by our representatives via email and orally."
"The Sierra Club Loma Prieta Chapter supports the adoption of the staff recommended reach codes including Two-Way AC, FlexPath, and Electric Readiness policies. Our communities are already directly experiencing the impacts of the climate crisis, and the time for bold action is now. Two-Way AC policies encourage residents and businesses to replace broken air conditioners with electric heat pumps. [...] FlexPath policies for single family homes encourage residents to install energy efficiency measures, such installing electric appliances or solar panels, during additions or alterations affecting 1,000 square feet or more. [...] Similarly, Electric Readiness policies also encourage single family residents to install electric ready circuits or conduits when they are conducting an alteration that would make electric readiness convenient."

A massive threat looms over one of our most cherished natural treasures. San Bruno Mountain is not just any mountain, it is a sanctuary for endangered butterflies, a haven for rare plants, and a refuge of unparalleled ecological significance. The proposed project threatens to unravel the delicate balance of this natural treasure, and we urge you to take action to protect it.
The City of Brisbane is considering a plan to build a massive 1.3 million-square-foot warehouse, 100 feet tall, right in the heart of San Bruno Mountain, at the historic Guadalupe Quarry.
This industrial facility would bring hundreds of workers (1,500!) and an incredible amount of traffic through our city and into the heart of sensitive habitat. Sign the petition today.
