Hudson, NH Environmental Rules: Stormwater Management (2026)

6 alongside the New Hampshire Stormwater Manual. Section 290-3 requires an applicant to submit a Stormwater Management and Erosion Control Plan (SMECP) to the Planning Board and Town Engineer whenever a proposed development, redevelopment or subdivision crosses any one of several thresholds: a cumulative disturbed area exceeding 20,000 square feet, work within an applicable wetlands buffer or adjacent wetlands, or any disturbance within a defined 'critical area,' meaning land within 50 feet of a stream, bog or water body, disturbed areas over 2,000 square feet in highly erodible soils, or disturbances longer than 25 feet on slopes steeper than 10% (§ 290-2).

The regulation sets post-construction and construction-phase standards (§§ 290-5, 290-6), requires inspection and maintenance plans (§ 290-9), and where its standard conflicts with another Town, state or federal rule, the more restrictive standard controls under RSA 676:14 (§ 290-1D). Enforcement runs through the Town Engineer, who issues a written Notice of Violation and Cease and Desist Order by certified mail when site conditions breach the regulation or an approved plan, and who can escalate to Superior Court injunctive relief or a revoked subdivision, site plan or building permit approval if the owner doesn't correct the violation within the stated time frame (§ 290-12).
