SAN DIEGO–The County’s Board of Supervisors voted unanimously to reduce greenhouse gases in the county by keeping a lot more construction debris from unincorporated communities out of local landfills.
The vote would change the county’s ordinances related to diverting construction and demolition materials and supports the County’s Climate Action Plan and its Strategic Plan to Reduce Waste.
The ordinance changes would keep more organic waste like wood and cardboard from rotting in local landfills and creating greenhouse gases including methane. They would also maximize local landfill space by keeping out an estimated 11 times more debris that can be recycled; and allow more demolished concrete and asphalt to be used for new construction.
The changes would apply to construction and grading in the county’s unincorporated communities and take effect on April 1.
The county’s existing ordinance applies to construction projects at least 40,000 square feet in size. The changed ordinance would apply to projects as large as 1,000 square feet. County public works officials estimate that the change would increase the amount of construction debris kept out of landfills from 4,000 tons a year to 44,000 tons a year.
The County’s Department of Public Works plans to post more information about the ordinance changes on its website.
