New Bedford's Environmental Rules: The Rules That Matter

Every city handles environmental rules a little differently. In New Bedford, Massachusetts, there are 5 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Flood Zones

New Bedford's Floodplain Overlay District covers every FEMA-mapped special flood hazard area in the city and requires a permit for any development within it, from new buildings to fences, sheds and grading. Development must also comply with the state building code and DEP wetlands regulations.

Key details: District basis: FEMA Bristol County FIRM dated 7/6/2021. Permit required for: Nearly all development, including sheds/fences. Floodplain administrator: Inspector of Buildings. Zone VE new construction: Must sit landward of mean high tide. State code overlay: 780 CMR floodplain/coastal hazard provisions apply.

Developing in the Floodplain Overlay District without the required permits, or violating the encroachment and dune-alteration prohibitions, is a zoning violation. Section 5130 sets the penalty at $300 per offense, with each day of noncompliance a separate offense, and the Inspector of Buildings, as floodplain administrator, enforces compliance under Section 5120 alongside the Conservation Commission's wetlands jurisdiction.

This is one of the stricter rules in New Bedford's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Vehicle Idling Restrictions

New Bedford outlaws letting any parked motor vehicle idle for more than ten consecutive minutes. Emergency vehicles responding to calls, utility crews working on utility facilities, traffic jams beyond a driver's control, and refrigeration units on delivery trucks are the only exceptions, and the registered owner is presumed responsible whenever a parked vehicle is caught idling.

Key details: Idling limit: 10 consecutive minutes, parked. Exceptions: Emergency, utility, traffic jam, refrigeration. Owner liability: Prima facie evidence, § 23-27(c). Penalty section: § 17-18(j), Chapter 17. Governing section: § 23-27.

Idling a parked vehicle past the ten-minute mark is the violation itself; officers do not need to see the driver return to write the ticket, since a parked, idling vehicle is prima facie evidence against its registered owner. The fine is set by Section 17-18(j) of Chapter 17, New Bedford's general penalty and enforcement chapter, rather than by Section 23-27 itself.

Flood Elevation Requirements

In New Bedford's unnumbered A flood zones, subdivisions or developments larger than 50 lots or 5 acres, whichever is less, must supply base flood elevation data. Along undesignated floodways, the best available federal, state or local data is used to bar any encroachment that would raise flood levels.

Key details: BFE data trigger: Subdivisions/developments over 50 lots or 5 acres. Applies in: Unnumbered A zones (no FEMA-set BFE). Floodway encroachment standard: Best available federal/state/local data. Zone A elevation basis: Building department's own data review. AO/AH zones: Require drainage paths around structures.

Developing a qualifying subdivision or large project in an unnumbered A zone without supplying base flood elevation data, or encroaching on a floodway in violation of the best-available-data standard, is a zoning violation. Section 5130 sets the penalty at $300 per offense, with each day of noncompliance a separate offense, enforced by the Inspector of Buildings as floodplain administrator.

Stormwater Management

New Bedford bars anyone from altering land within the city without first obtaining a stormwater management permit (SMP) under Code of Ordinances § 16-134(a). The commissioner of the Department of Public Infrastructure serves as the city's stormwater authority, reviewing applications for new development, redevelopment, and linear projects like footpaths under the city's stormwater rules and regulations.

Key details: Permit requirement: SMP required before altering land (§ 16-134(a)). Stormwater authority: Commissioner of Public Infrastructure (§ 16-132(a)). Exemptions: Small roofs, accessories, existing landscaping (§ 16-134(b)). Fine: Up to $300 per violation per day (§ 16-139). Adopted: November 4, 2015.

Altering land without an SMP, or violating a permit's conditions, exposes the responsible party to civil enforcement including an injunction, plus criminal fines up to $300 per violation per day, or noncriminal citations up to $300 per violation per day under M.G.L.A. c. 40, § 21D and c. 40U, all under § 16-139. The Department of Public Infrastructure and its agents may enter private land to inspect and sample for compliance.

This is not one of those rules that cities tend to ignore. New Bedford actively enforces its stormwater management requirements.

Erosion Control

New Bedford requires phased developments that must file a Development Impact Statement to describe exactly how construction will control erosion and sedimentation, naming methods such as sediment basins, mulching, matting, temporary vegetation, and covered soil stockpiles, and requires all site-plan-reviewed projects to minimize erosion generally.

Key details: DIS erosion methods named: Sediment basins, mulching, matting, temp vegetation, stockpile covering. DIS trigger: Phased development, at SPGA's discretion. Broader erosion standard: Site Plan Review, § 5471(i). DIS prepared by: Registered engineer/landscape architect/surveyor team. Approval lapse period: 3 years without substantial use.

No building permit issues without an approved site plan (Section 5450), and Section 5457 bars any deviation from an approved plan, including its erosion-control measures, without a Planning Board-approved modification. Site plan approvals, and the erosion-control commitments tied to them, lapse after three years without substantial use, forcing a new application under Section 5480.

The rules around erosion control in New Bedford lean permissive, but that does not mean anything goes.
