Green Bay, WI Environmental Rules: Stormwater Management (2026)

The stormwater article in Chapter 16 applies under § 16-80 to land disturbance meeting set thresholds, plus any activity the city finds likely to overload downstream drainage; state agency projects are excluded. Before work starts, § 16-82(a) requires a permit from the Director of Public Works. The application package under § 16-82(b)(1) must include a stormwater management plan meeting § 16-83, a maintenance plan and recorded maintenance agreement meeting § 16-84, any needed easements, engineered facility plans, professional engineer certification, a nonrefundable administration fee, any fee-in-lieu payment under § 16-81, and performance security if the Director requires one.

The Director has 30 business days from a complete submittal to approve or disapprove under § 16-82(c)(1); missing that deadline is treated as a disapproval, letting the applicant revise the plan or appeal. Where security is required, it cannot exceed the estimated construction cost of the stormwater practices plus 15 percent, and it is not released until a professional engineer certifies as-built compliance under § 16-82(d). Permit holders must notify the Director at least two business days before starting work and within five business days of finishing, and completed practices must pass a final inspection before the permit closes out. A denied applicant, or anyone facing enforcement action, can appeal to the Improvement and Service Committee under § 16-86.
