Concord: Ash/Debris Cleanup Advisory


Last updated: April 24, 2018, 9:41 am

The large structure fire in Concord consisted primarily of construction materials (predominately wood). Residents should avoid direct contact and inhalation of ash/debris that was produced by the fire. Residents may use a mild soap and water to clean up ash/debris. To minimize dust generation, residents should consider lightly dampening ash/debris prior to commencing sweeping activities. Swept up ash/debris may be placed in a standard household trash receptacle. Any towels or cleaning materials should be rinsed in a sink that drains to a sanitation sewer. Residents should avoid washing or sweeping ash/debris into storm drains, as this will result in pollution accumulating in nearby creeks and rivers.

Land Use Permits for Development Projects Involving Hazardous Waste or Hazardous Materials Chapter


Contra Costa County's Industrial Safety Ordinance includes requirements for evaluating development projects that involve hazardous waste or hazardous materials (Article 84-63.2 of the County Ordinance Code). Development projects, as defined by the ordinance, that meet specified thresholds are required to perform a hazard score for the development project to determine if a land use permit will be required.
