Summary
San Mateo specifically regulates leaf blower operation under Chapter 10.80 in addition to the general noise ordinance. Leaf blowers must comply with both the noise standards in Chapter 7.30 and the specific provisions of Chapter 10.80. Operation is limited to construction-permitted hours.
Existing law imposes various limitations on the emissions of air contaminants for the control of air pollution from vehicular and nonvehicular sources. [...] This bill would require the state board, by July 1, 2022, consistent with federal law, to adopt cost-effective and technologically feasible regulations to prohibit engine exhaust and evaporative emissions from new small off-road engines, as defined by the state board. The bill would require the state board to identify and, to the extent feasible, make available funding for commercial rebates or similar incentive funding for the transition of commercial gasoline-powered landscaping equipment to zero-emission equivalents.
