Comprehensive Wastewater Management Plan — Phase 1 Operational

Mashpee's Water Resource Recovery Facility (WRRF) became operational in the summer of 2025, treating wastewater under Phase 1 of the town's long-term nitrogen management plan. Phase 1 property owners have received official connection notices. The project is designed to reduce nitrogen pollution threatening Popponesset Bay, Waquoit Bay, and the Mashpee-Wakeby Pond system.

Phase 2: In July 2023, the Sewer Commission and Select Board unanimously approved Phase 2 of the Watershed Nitrogen Management Plan. Planning for additional sewer collection zones and a cluster treatment system near Mashpee-Wakeby Pond is underway.

Resident impact: Homeowners in Phase 1 zones face connection fees, betterment assessments, and long-term sewer bills. Phase 2 will extend infrastructure obligations to additional neighborhoods.

$26 Million Wastewater Treatment System — Approved October 2025

In October 2025, Mashpee voters approved a controversial $26 million stand-alone wastewater treatment system to address pollution from aging septic systems. The proposed underground sewage treatment plant has drawn opposition from neighbors concerned about its impact on residential quality of life and property values, and debate about whether alternative septic technologies should have been considered.

Why it matters: The project commits the town to significant new infrastructure spending. Residents in affected areas will bear direct costs, and the decision shapes how Mashpee addresses nitrogen pollution for the next generation.

New Police Station — Approved May 2025

At the May 2025 Annual Town Meeting, Mashpee voters approved funding for a new police station on Hicks Drive. The existing station, with a two-story addition built in 1990, had not undergone significant renovation in over 30 years and suffered from poor air quality, mold, plumbing failures, flooding, and rodent infestation. The approval required a Proposition 2½ debt exclusion ballot question, which passed at the May 10 town election.

Why it matters: Public safety infrastructure directly affects the working conditions of first responders and the town's ability to serve residents. The project also represents a major capital commitment for taxpayers.

Mashpee Wampanoag Tribe — Land-in-Trust Secured

In April 2024, the U.S. Supreme Court declined to hear a challenge to the Mashpee Wampanoag Tribe's 321-acre land-in-trust designation, effectively ending years of litigation and confirming the reservation — roughly 150 acres in Mashpee and 170 acres in Taunton — as protected tribal land. Federal legislation introduced in January 2025 (S.236) would further authorize 99-year land leases on trust property.

Why it matters: The tribe's land status affects local planning, zoning, and the broader relationship between tribal sovereignty and municipal governance. The resolution provides long-sought stability for the Wampanoag community and clarity for town-level land-use decisions.

Select Board Turnover — May 2025 Election

The May 2025 town election brought two new members to the Mashpee Select Board: Tracy Kelley, a Wampanoag tribal member and executive director of the Wôpanâak Language Reclamation Project, who won a two-year seat; and Michael Richardson, who won a three-year seat. The election marked a notable moment for tribal representation in town government.

Why it matters: Select Board composition shapes the town's direction on budgeting, development, public safety, and the town-tribal relationship. New members bring fresh perspectives on longstanding issues.
