Grand Forks, ND Environmental Rules: Stormwater Management (2026)

The Land Development Code channels every land-disturbing project through the city engineer's office before dirt moves. Under § 15-0903, no subdivision or plat can be approved, and no building permit issued, until a stormwater management plan or waiver has been obtained; land-disturbing activity itself is barred until the plan or permit is in place. Applicants file two sets of drawings plus a hydrologic and hydraulic analysis under § 15-0904, pay a council-set processing fee, and wait for the city engineer to approve, approve with conditions, or deny; complex or controversial plans go to the city council for public comment.

Approval expires one year after issuance unless construction has started, though the engineer may grant one extension of up to another year on written request, acknowledged within fifteen days and decided within thirty. Section 15-0905 sets the technical bar: post-development peak flow at the two-, ten- and hundred-year design storms cannot exceed pre-development peak flow without the city engineer's written approval or an approved off-site facility, and all computations must carry a state-registered professional engineer's seal. The rules extend beyond the city limits into Grand Forks's extraterritorial jurisdiction, and section 15-0901 states that where this article conflicts with an erosion control, floodplain, or other adopted regulation, the more restrictive standard governs.

The city engineer retains inspection rights over any public or private stormwater system at any time and can require drainage easements as a condition of approval.
