Climate committee endorses harbor support letter after debate over stormwater and energy measures

The Climate Resiliency Committee voted unanimously to endorse a draft letter of support for the harbor improvement project after a lengthy discussion about stormwater mitigation, energy choices and funding.

Committee members heard a presentation from project staff and the engineering team about site conditions and stormwater treatment that the presenter said meets MassDEP stormwater standards. The project team told the committee that a $1,500,000 grant from the Seaport Economic Council and a proposed reallocation of existing waterway fees would fund the work; the presenter said a December bid price of roughly $6,000,000 is likely to rise and the original estimate was about $8,000,000.

Why it matters: committee members said the harbor is currently shunting most runoff directly to the water, and they framed the endorsement as a way to secure permitting and grant timelines while reserving further scrutiny of the project’s sustainability and resiliency features before town meeting. The committee added brief language to the letter noting the project "presents a resiliency and hazard mitigation opportunity" and that it addresses the town’s urgent stormwater runoff problem.

Tom Andrade, the project engineer, described the stormwater system planned for the site. "It treats everything up to the 25 year storm," Andrade said, explaining the design uses deep-sump catch basins, oil separators and underground leaching chambers embedded in stone to capture sediment and hydrocarbons before infiltration. He said the design recharges up to and in many respects above the town’s 25-year treatment standard and is designed to meet MassDEP criteria.

Committee members pressed for data. One member asked for the stormwater performance and maintenance plan; Andrade said the stormwater report was filed, approved by the conservation commission and is available for review. Another member asked how often catch basins would be pumped; Andrade said DPW typically inspects and pumps basins on a roughly three- to four-year cycle and that operations-and-maintenance tasks are included in the project plan.

Several members raised concerns about energy and long-term resiliency. Committee member Christine said the project "is not a climate-forward project" because the design includes a natural gas connection for a garage and lacks EV charging and full renewable systems. Others urged supporting the project now, arguing the stormwater improvements and flood-hardening measures are urgent and that future phases could address carbon footprint and renewable energy. The chair and other members proposed, and the committee adopted, language welcoming future resilience and energy improvements.

On the funding and policy side, the harbormaster explained the proposed waterways capital improvement fund would be created through a reallocation of revenue percentages rather than moving existing principal from the dredge fund. The harbormaster said the dredge fund held about $1,400,000 before this year’s dredging and that dredging this year cost about $240,000.

Before the endorsement vote, members discussed the risk that altering the grant-funded design (for example, substituting less paving) could jeopardize the Seaport Economic Council or other grant awards. Tom noted that framing the RFP with alternates or substitutions (for example heat pumps, solar or battery options) could allow contractors to propose energy upgrades without reissuing the base procurement.

The committee also discussed other grant avenues — FEMA, NOAA coastal resilience, CWSRF and EPA programs — and the potential to pursue Green Communities and other energy grants for later phases. Committee members asked staff to circulate the stormwater and mitigation documentation and to work with town administration on grant strategy.

The committee adopted the amended letter by roll call. The chair moved to endorse the letter; a member seconded the motion; the committee approved it unanimously. Following the vote the presenter agreed to make the agreed amendment and circulate the letter for signature.

What’s next: committee members asked to receive the stormwater report and the latest hazard mitigation plan draft before the next meeting so they can review performance numbers and discuss outreach and grant submissions. The committee scheduled follow-up among staff for grant coordination and suggested the town could include alternate energy language in the procurement to allow later energy retrofits.

Representative quote: "The committee feels that this is an excellent step in addressing the most urgent problem of stormwater runoff," a committee member said during discussion.

The meeting adjourned after approval of minutes and routine administrative items.
