It took three years, the threat of a legal battle and a lengthy mediation process, but the developer of a contentious housing development proposed at the Bay Pointe Club received the Planning Board's blessing to move forward.

“Can I get an amen?” Planning Board Chair George Barrett asked Monday night after members unanimously OK’d the plans.

Rhode Island-based Stonestreet Corporation proposed the project in 2014, two years after purchasing Bay Pointe for $1.4 million. However, it met opposition from the Planning Board as members expressed concern over sewer capacity and housing density. Stonestreet then filed legal action against the board in Land Court. Instead of going to trial, Stonestreet and the Planning Board agreed to mediation.

Those sessions took place behind closed doors, overseen by Concord-based Attorney Mark Bobrowski, and resulted in the new proposal, which Fay and his legal team unveiled last month.

Approval came after developer Timothy Fay, president of Stonestreet Corporation, agreed to two major concessions for the project.

First, residences in the 84-unit housing project will be tied into a sewer system that feeds into one central pump. Initially, Stonestreet proposed using individual “grinder” pumps for each residence. That style of pump grinds household wastewater into a slurry before sending it to a central sewer system or septic tank.

The second concession changed plans from what would have been a higher density project to one with more space for future residents. Both changes were made after board members expressed concerns over those issues, said Barrett.

Monday marked the second time the board met with the developer since opening a public hearing on the new plans six months ago. Barrett said the hearing had been continued for so long due to engineering plans not being finalized and that scheduling conflicts also delayed the process.

Barrett said Monday’s meeting and the previous one, held July 24, offered board members an opportunity to “fine tune” the agreement.

Monday’s approval allows Stonestreet to begin construction on Phase 1 of the project. That phase includes the construction of 28 units. Planning Board approval is still required for Phases 2 and 3 of the project to build the remaining units. Planning Board and Stonestreet officials did not provide an estimate for when construction might begin.

Barrett noted that Stonestreet is still subject to a 21-day appeal period during which time the board’s decision may be challenged.
