North Bergen, NJ Environmental Rules: Stormwater Management (2026)

Stormwater management in Hudson County is complicated by legacy combined sewer systems, extreme impervious surface coverage (70%+ in Jersey City/Hoboken), and low elevation making much of the county flood-prone during Sandy-scale storms. NJ DEP Stormwater Management Rules N.J.A.C. 7:8 require stormwater plans for projects disturbing 1+ acres or increasing impervious surface by 0.25+ acres. Jersey City MS4 Stormwater Program operates under NJ DEP permit NJS0157686 and requires compliance with Minimum Control Measures covering public education, illicit discharge detection, construction site runoff, post-construction stormwater, and municipal operations. Hoboken MS4 program is nationally recognized for innovation following Hurricane Sandy — the Rebuild by Design Hudson River project has delivered major green infrastructure including ResilienCity Park, underground detention tanks, and street-level bioretention. Hoboken's SW quadrant (particularly near Washington and Newark Streets) remains a chronic flood area. Jersey City operates multiple Combined Sewer Overflow (CSO) outfalls into the Hudson and Hackensack Rivers which are being addressed under a NJ DEP Long Term Control Plan. Property owners must maintain post-construction stormwater facilities; maintenance failures trigger enforcement. Illicit discharge to storm drains (painting, grease, pool water, construction runoff) carries significant penalties. New construction must include green infrastructure where feasible.
