Inspection Requirements for Wisconsin
Construction projects that disturb one or more acres—or smaller sites that are part of a larger common plan—commonly require stormwater permit coverage in Wisconsin. Eligibility, exemptions, local approvals, and project-specific conditions vary, so confirm coverage under the WPDES Construction Site Storm Water Runoff General Permit before construction begins.
Operational Insight
This schedule combines recurring and event-driven duties. Record rainfall or discharge events independently from the weekly calendar and document why each event did or did not trigger an inspection.
Specific State Nuance
Erosion Control and Storm Water Management plans must be separate documents.
