The City of Dixon owns and operates a stormwater drainage system that incorporates storm drain inlets and piping, several detention ponds, and serves eight drainage basins within the Dixon General Plan boundary. This system collects stormwater and drainage runoff, detains the said water runoff, and discharges into the Dixon Resource Conservation District ditch system south of the City limits. This ditch system, in turn, drains into Hass Slough and navigable waterways to the south.
The City stormwater drainage collection system is a separate piping system independent from the sanitary sewer collection system. The stormwater system, per State requirements, is intended to collect rainwater runoff only.
New development and redevelopment projects are required to comply with the State's General Permit regarding stormwater runoff. The city uses the Permit, City Engineering Standards, and California Stormwater Quality Association's Best Management Practices Handbook for reviewing projects for compliance with the permit.
Flooding conditions: if citizens of Dixon or unincorporated areas are in need of sand and sandbags for flooding conditions they can pick up the sandbags at the Dixon Fire Department located at 205 Ford Way. Sand for City residents is located at the old Ace Hardware Site (N. Jackson at West A). Sand for County residents is located at the end of Industrial Way.
