what we do

Welcome to the 350 SV Los Altos City Team Page! We hope you will join us in our efforts to make Los Altos a more sustainable city. Together, we can unite our voices and demand that Los Altos city legislators recognize the climate crisis we are facing. At the moment, all energy is focused on the challenging task of passing all-electric building "Reach Codes" to end the use of fossil gas.
