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.

Mosquito-borne Illnesses

Some mosquitoes carry diseases that infect people when they bite us. The diseases can vary by species – there are different kinds of mosquito – and by region.

In Contra Costa County, the only disease that mosquitoes are known to give humans is West Nile Virus.

The best way to avoid mosquito-borne illnesses is to avoid bites.

  • Use insect repellant
  • Cover up – wear long-sleeved shirts and pants, especially at dawn and dusk
  • Use screens on windows or doors when it gets warm, or just use air conditioning

Contra Costa residents can also help to reduce the local mosquito population.

  • Keep mosquitoes from breeding in your home or garden
  • Report neglected (green) swimming pools, ponds or troughs of stagnant water
  • Get help if you notice unusual mosquito activity

The Mosquito & Vector Control District offers free services and advice about mosquitoes at or 925-771-6196.
