The final plan for the Thames River Heritage Park will be presented to the public at a meeting at 7 p.m. Wednesday at Groton City Hall.

Alan Plattus, executive director of the Yale Urban Design Workshop, will give an overview of the plan and its recommendations. Members of the steering committee for the park will talk about implementation.

Penny Parsekian, chairwoman of the steering committee, said Friday that representatives of U.S. Sen. Christopher Murphy and Rep. Joe Courtney, D-2nd District, are planning to attend, along with officials from the state Department of Energy and Environmental Protection and the Department of Economic and Community Development.

Parsekian said she is hoping for a good turnout.

“This is our last chance to show state leadership that this is a well-supported idea,” she said.

The plan was written by the urban design workshop and recently was approved by the Board of Directors of the Avery-Copp House, the organization that fostered the formation of the steering committee two years ago.

The idea for the park, which dates back to the 1980s, is to tie independent historical attractions on the Groton and New London sides of the Thames River into a network connected by a water taxi, common signage, programming and coordinated events.

Anchor sites would be Fort Griswold and Fort Trumbull state parks, the proposed National Coast Guard Museum and the Submarine Force Museum. A dozen smaller sites also would be included.
