Flood Control Maintenance


The Flood Control Maintenance Crew maintains approximately 75 miles of improved channels that are divided drainage zones throughout the County, including incorporated cities. These channels are constructed of earth, rip-rap, grouted rip-rap or concrete.

The crew also maintains smaller dedicated drainage facilities in the unincorporated parts of the County, also known as County-wide Drainage.

In addition to the channels we also maintain 4 dams, and approx. 35 detention basins and approx. 25 trash racks.

Routine maintenance for these facilities would include but not be limited to:

  • Ditch cleaning
  • Structure repairs
  • Channel Bank Repairs
  • Channel desilting
  • Fence repairs
  • Log-jam removal
  • Tree trimming and removal
  • Access road grading
  • Weed abatement

Vegetation Management

The Vegetation Management crew cuts, and/or removes vegetation growing in improved creeks and flood control facilities each year. Weeds are sprayed or cut to keep water flowing with minimal obstruction during storm events and to prevent grass fires on the Flood Control District's property during the hot dry summer months. Woody shrubs and trees are also pruned or removed to prevent damage during storm events.
