Lodi, CA Environmental Rules: Erosion Control (2026)

14, Lodi's stormwater management and discharge control ordinance, and subsection (B) is the construction-specific piece of it. It requires anyone performing construction activity in the city to prevent pollutants from reaching the stormwater conveyance system and to comply with the current California NPDES General Permit for construction activity, on top of the chapter itself. The standard applies to every project regardless of size that has soil disturbance or activity exposed to stormwater, and at minimum requires best management practices covering erosion and sediment control, soil stabilization, dewatering, source controls, pollution prevention and prohibited discharges.

Larger projects covered by the state's construction general permit must submit their WDID number and stormwater pollution prevention plan, or SWPPP, to the city before a construction permit is issued or improvement plans are approved; smaller projects under an acre that fall outside the state permit instead submit an erosion and sediment control plan, or ESCP, and the accompanying ESCP worksheet. Subsection (B)(3) backs this with inspections: because Lodi holds a Phase II MS4 NPDES permit, the city inspects construction sites with exposed soil disturbance using an inspector who is a qualified SWPPP practitioner or is supervised by one, and bills the inspection cost to the project owner.

Inspection frequency scales with the state's risk rating: projects with no coverage or an erosivity waiver get only a pre-disturbance and completion inspection, Risk 1 and 2 projects get monthly inspections in between, and Risk 3 projects get twice-monthly inspections until the project is finished. 110.
