Planning board backs zoning updates to allow solar carports and three renewable categories with conditions

The Lincoln Planning Board voted to recommend zoning amendments that revise how renewable energy installations are classified and regulated, adding specific categories for utility-scale, roof-mounted accessory, and minor ground-mounted systems and setting application standards for special-use review.

"So what we're proposing here is, to kind of split out the the renewable energy into 3 categories," Stephanie, a planning staff member, said while outlining the draft changes. The proposal would: (1) return utility-scale renewable energy facilities to special-use status in ML and MG industrial districts as principal uses; (2) permit roof-mounted accessory solar across applicable zones; and (3) treat minor ground-mounted renewable systems as special-use permits, with a proposed limitation that residential ground mounts be sized to produce no more than 25% of the primary use’s energy demand.

Nut graf: The board aimed to accommodate rooftop leasing and commercial installations while limiting potential neighborhood impacts from large ground-mounted arrays on residential lots. The Technical Review Committee suggested the 25% limit to ensure ground-mounted systems on residential parcels serve on-site demand rather than become de facto commercial generation sites.

Board members and the applicant’s attorney discussed practical details likely to arise in permit review. Attorney Michael Minow, who represents a prospective applicant proposing solar carports on an industrial lot in the Salesville Mill Complex, raised concerns about the ordinance’s 15-foot height limit for carports; he suggested a higher allowance for canopy-style carports intended to accommodate box trucks. Board members generally favored retaining the 15-foot standard and suggested variance requests for exceptions rather than changing the rule broadly.

The draft also retains standard decommissioning financial-security language for larger projects; Minow asked that decommissioning bonds not apply to canopy/carport systems where the solar developer typically operates under long-term leases. Board members acknowledged both the need to protect the town from orphaned infrastructure and the argument that small canopy systems present less decommissioning risk. The planning staff noted decommissioning estimates would typically rely on projected removal and recycling costs and could include escalation factors.

Other points discussed included the proposed 25% production cap (staff agreed it should apply only to residential ground mounts) and that rooftop leasing or carport installations in industrial zones could be treated differently from residential ground-mounted systems. The board also discussed that state-level interconnection rules and utility crediting may impose additional limits beyond local zoning.

After discussion, Member Riley moved and Member Almond seconded a motion to send a positive recommendation to the Town Council with the discussed changes. The chair declared, "The ayes have it."

Ending: The planning board forwarded the revised renewable-energy language to the Town Council; the recommendations emphasize special-use review for ground-mounted systems, keep rooftop accessory solar broadly permitted, and leave technical permits, interconnection, and fire/building compliance to state and permitting authorities.
