After years of work and arguments, Port Jefferson’s controversial village development plan has become final.

The board of trustees unanimously adopted the comprehensive plan at a meeting on Monday, but Trustee Bruce Miller said in an interview the following morning that he plans to retroactively change his vote at the next board meeting.

Miller said he got “bogged down” during the board’s discussion about its agenda items, and didn’t mean to vote in favor of adopting the plan.

The comprehensive plan is a guideline for future development in Port Jefferson Village, largely focusing on the waterfront commercial area downtown and the short but troubled uptown corridor that runs between North Country Road and the Long Island Rail Road tracks. It aims, for instance, to revitalize upper Port by making it more pedestrian-friendly and bringing in more apartments. Downtown, the plan includes adding recreational and green space near the water and widening Main Street.

Residents and former members of the Comprehensive Plan Advisory Committee, with the support of Miller, have long sparred with the administration over the plan, citing fears that it would add too much density to what they want to be a quaint village, snarl traffic even further on busy roads and bring in more cars than there is space to park them.

Miller echoed those concerns on Tuesday, and said he also opposes adopting the plan for procedural reasons — he said he hasn’t yet seen a findings statement, which is a document certifying that the village met the requirements of the State Environmental Quality Review Act in its study of the plan’s environmental impact.

The village board approved that findings statement at Monday’s meeting.

Still, there have been voices of support for the plan, including from the other four board members and from other residents. And recent approval from the Suffolk County Planning Commission was the final stamp the village needed before adopting it.

While the commission issued a list of recommendations relating to the plan’s impact on traffic, density, taxes and parking, the village sent a response letter in which it disagreed that more study was required on most of those items. To the Planning Commission’s suggestion, for example, that the village conduct “an analysis of the impacts of increased rental housing” in Port Jefferson, the village responded in May that “it is unclear how the type of ownership status of housing units alone would impact community character, and the suggestion that because a property is a rental property that it would then have a negative impact on the community is unfounded.”

The village’s response also noted that the apartments would likely serve single adults and couples without children, which is “the same demographic that … Long Island is seeking to retain, as the young contribute to our workforce and the [retirement-aged residents] continue to enjoy recreation and spend using their discretionary income.”

Suffolk County Planning Director Sarah Lansdale wrote in an email later last month that the village gave the issues “proper procedural review” and took “a hard look at the issues raised by the commission.”
