The only realistic approach to reducing Red Zone pollution in San Diego is focusing support for electrification of the diesel and gas transport sector. Heavy industry within embedded neighborhoods are not good candidates for LEZ. Pink Zone could be LEZed as they overlay our local freeways... but we still need to solve for those unsupported "last few miles" to the transport corridors. (Bicycles/skateboards are not options for us older/risk adverse folks.)
