The Board of Supervisors finds and declares the following:
Particulate matter and other air-borne materials have been shown to have an adverse impact on public health, including asthma and other respiratory illnesses; and
Particulate matter and other air-borne materials may have negative impacts on the environment, particularly in ecologically sensitive areas; and,
Vehicles transporting uncovered dirt and other aggregate materials may facilitate the release of particulate matter into the environment;
Vehicles that transport dirt and other aggregate materials often drive through residential and ecologically sensitive areas; and,
Covering loads of aggregate material during transit within the City would prevent the entrainment of particulate matter into the environment; and,
Under this Chapter, the City and County of San Francisco wishes to exercise its power to make economic decisions involving its own funds as a participant in the marketplace and to conduct its own business as a municipal corporation to ensure that its activities do not increase the amount of particulate matter present in residential and other ecologically sensitive areas. The City enacts this Chapter to require City Departments and City contractors to cover their loads when transporting dirt and other aggregate materials in the City.
This Chapter applies the Precautionary Principle to the determination of best management practices when transporting aggregate materials for City construction projects to minimize negative impacts on air quality and human health.
