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:
Channel Bank Repairs
Tree trimming and removal
Access road grading
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.
