Summary

New development inside New Bedford's Kings Highway transit-oriented overlay district must meet Illuminating Engineering Society of North America design guidelines for outdoor lighting, providing needed safety illumination while reducing skyglow. The standard sits in the overlay district's design chapter, not a citywide fixture-shielding law.

4273B(iii). Lighting. Light levels shall meet or exceed the minimum design guidelines defined by the Illuminating Engineering Society of North America (IESNA) and shall provide the illumination necessary for safety and convenience while preventing glare and overspill onto adjoining properties and reducing the amount of skyglow.

Full Breakdown

), requires that light levels meet or exceed the Illuminating Engineering Society of North America's minimum design guidelines, provide the illumination needed for safety and convenience, and reduce skyglow. The identical clause reappears at Section 4273C(iii) for New Bedford's City Center TOD overlay, so the standard covers both transit-oriented districts but no others. As-of-right KH-TOD uses are subject to Site Plan Review under Section 5400 (Section 4232B), and the Planning Board may adopt further Design Standards and Guidelines under Section 4233B, so the IESNA benchmark is applied and checked during that review rather than through a separate lighting permit.

The ordinance text sets no specific lumen, color-temperature, or full-cutoff-fixture number; compliance is measured against the outside IESNA guideline itself. Outside the KH-TOD and City Center TOD boundaries, the Zoning Ordinance contains no general dark-sky or skyglow-reduction requirement.

Violations & Fines

Because the standard is a design requirement checked during Site Plan Review, non-compliance blocks approval rather than triggering a fine directly: the Planning Board can deny or condition site plan approval under Section 5470 until a lighting plan meets the IESNA benchmark, and under Section 5450 the Inspector of Buildings cannot issue a building permit without that approved site plan.

Frequently Asked Questions

Does New Bedford have a citywide dark-sky lighting ordinance?
No. The IESNA-based lighting standard in Section 4273B(iii) only binds new development inside the Kings Highway Transit-Oriented Development Overlay District, with an identical clause at Section 4273C(iii) for the City Center TOD overlay. Projects elsewhere are not held to that guideline in the general zoning code.
What lighting standard applies inside the KH-TOD overlay?
Section 4273B(iii) requires light levels to meet or exceed the Illuminating Engineering Society of North America's minimum design guidelines, providing needed safety illumination while preventing glare, overspill onto adjoining properties, and reducing skyglow. The Planning Board checks this during Site Plan Review before approving the project.
Who enforces the KH-TOD lighting standard?
The Planning Board reviews lighting plans as part of Site Plan Review under Section 5400, and the Director of Inspectional Services cannot issue a building permit for a KH-TOD project until the Planning Board has approved a site plan that meets Section 4273B's design standards.
