Hamilton, NJ Environmental Rules: Erosion Control (2026)

Section 550-71, the general-principles section that opens Hamilton's zoning districts article, states flatly that no land area may be disturbed for development by any person, partnership, corporation, municipal corporation or other public agency in the Township unless a soil erosion and sedimentation control plan has first been approved by the United States Department of Agriculture Natural Resources Conservation Service. The applicant must hand proof of that federal approval to both the Township Engineer and the Township Planner before any clearing, grading or construction activity can begin, and every other development regulation in Chapter 550 still has to be satisfied on top of that approval.

The stormwater management standards at § 550-113 reinforce the same goal on the construction side: outfalls, flare-end sections, headwalls and erodible soils around detention basins must be adequately protected according to the Standards for Soil Erosion and Sediment Control in New Jersey, and outlet devices must be designed so discharge velocities do not cause additional erosion off-site. A separate site development stormwater plan is required under Chapter 577 for developments that disturb enough land to trigger the Township's stormwater ordinance, layering a second, more technical review on top of the NRCS sign-off.

Because approval has to come from a federal conservation agency rather than a municipal board, an applicant typically works through the Mercer County Soil Conservation District's certification process to get a plan NRCS will approve, then files that paperwork with engineering before a permit is issued.
