Residents and players clashed at public comment over noise and enforcement at the Heritage Park pickleball courts. Town Manager Collins defended staff actions after an unauthorized rally, reiterated park-hour enforcement, and announced a requirement for a quieter approved ball with an extension to allow players time to acquire it.

The board agreed to add and recommend a warrant article to reduce the Community Preservation Act (CPA) surcharge from 2% to 1% (and a related 1% to WIF); CPC chair Arden Russell and many residents urged the board to oppose any reduction, citing lost state match and fewer clean-water and historic preservation projects.

A heated public-comment segment focused on noise from Mashpee's eight pickleball courts. Residents and acoustic consultants urged mitigation and questioned a July 20 rule requiring a specific quieter ball; the town manager cited 16 formal complaints and potential nuisance litigation as reasons for the directive.

Engineering consultant GHD asked the board to authorize two SRF project evaluation form submissions for the Mashpee Wakeby watershed wastewater system and the Mashpee Roquoit Bay WRRF and collection system phase 3; the board approved the submittals.

Following numerous complaints from businesses about traffic, blocked access and staging, the Mashpee Select Board denied a MassDOT construction‑schedule extension for Route 28/151, and urged town staff to press the state and coordinate with local businesses before fall work resumes.

Residents urged a ban on personal watercraft at a Mashpee forum, citing safety, noise and environmental concerns; state and town officials said land-side management, enforcement resources and the land‑management agreement will guide any change and that no decision was made tonight.

The board approved awarding the HVAC and fire‑suppression contract for Quashion Intermediate School to Track Builders of North Attleboro for $10,757,150, a project funded by a previously approved town meeting allocation.

DPW and consulting staff summarized Mashpee's MS4 stormwater compliance work and detailed three retrofit projects—Mashpee Wakeby boat ramp, Santuet Pond Landing, and Adequate Park—reporting the first two as nearly complete and forecasting measurable phosphorus reductions.

Town planner asked the Select Board for a letter supporting a Community One‑Stop grant request of up to $500,000 to fund a traffic and design study of the Route 28 corridor; the board voted to provide the letter and emphasized the study would fund design work, not construction.
