On January 20, 2023, the Massachusetts Municipal Association announced the three winners of the MMA’s annual Kenneth Pickard Innovation Award during its 44th Annual Meeting & Trade Show. The award is named in honor of Kenneth Pickard, the executive secretary of the Massachusetts League of Cities and Towns from 1969 to 1973. 

Careful planning, community engagement shape Medfield State Hospital redevelopment
In 2014, the town of Medfield bought 128 acres of the old Medfield State Hospital property, and the purchase presented the community with both an opportunity and a challenge: What would be the best way to develop this property to benefit the community without detracting from Medfield’s overall character? Over the past decade, the town has undertaken an extensive planning process, studying the property, engaging a diverse group of stakeholders, and launching a robust community outreach program to determine the property’s future. When its efforts are complete, Medfield expects to have 334 new apartments (25% of which will be affordable), an arts and culture facility, and open space on the property, while preserving historic buildings and netting an estimated $700,000 annually in additional tax revenue for the town.

almost unanimously

The special town meeting (STM) on June 21, 2022 went quickly, and resulted in a virtually unanimous vote to proceed with the Land Disposition Agreement (LDA) with Trinity Financial to build 334 units of rental apartments (25% affordable) in the existing buildings at the former Medfield State Hospital site. Almost 700 residents were spread out between the gym, a tent in front of MHS, and a separate air conditioned area for seniors in the MHS library.

The Select Board and Trinity signed the LDA after the meeting. Next, Trinity will begin its permitting.

Update - March 30, 2022

On March 22, 20222, the Board of Selectmen voted to name an affiliate of Trinity Financial as the designated developer of the Medfield State Hospital and enter into a Provisional Designation Agreement with Trinity.  This designation, which is provisional, kicks off a period of additional due diligence for both parties ahead of a Special Town Meeting in June 2022, when voters will consider whether to approve a proposed sale of portions of the hospital campus.

During this period of due diligence, Trinity will have access to the Medfield State Hospital buildings and grounds for continued evaluation of existing conditions, to conduct environmental assessments and other studies, and to further develop its proposal for the campus. Trinity's consultants have been onsite everyday since March 29, 2022 conducting due diligence inside the existing buildings. They expect to be onsite through April 15. 

Simultaneously, the Medfield State Hospital Development Committee will initiate its next phase of evaluation of the proposal, including an updated analysis of impacts and benefits to the Medfield community. Trinity’s proposal is intended to fund all of the project’s infrastructure costs as part of the construction and according to Trinity’s projections is expected to generate over $700,000 per year in net tax revenues to the Town once complete.
