The drainage department staff is responsible for administration of the Phase II National Pollution Discharge Elimination System (NPDES) Stormwater Program in the unincorporated areas of Lucas County including 8 named townships: Jerusalem, Washington, Sylvania, Springfield, Spencer, Swanton, Monclova and Waterville. One aspect of the program is the plan review and construction inspection of Stormwater Pollution Prevention Plans (SWP3s) for new subdivision and site developments in the Phase II area. This program is designed to limit erosion and storm water runoff from construction sites and keep Lucas County in compliance with the NPDES Phase II regulations.


SWP3 Plan Review Requirements
Construction activities disturbing one or more acres of total land, or will disturb less than one acre of land but are part of a larger common plan of development or sale that will ultimately disturb one or more acres of land must submit a SWP3 for approval by the Lucas County Engineer’s Office.

The SWP3 must be submitted to the Lucas County Engineer’s Office with a completed SWP3 Review Submittal Cover Sheet and all of the required documentation per the document. See PDF documents below:
