CAMDEN — A new design for the seawall separating the Megunticook River and Camden Harbor from Harbor Park has been talked about by a group of Camden Public Library Trustees and town government officials.

The seawall begins at the end of a massive stone wall that contains the dam sluiceway, then takes a turn and wraps around the base of Harbor Park.

The group met for a second time Aug. 25, at the request of town officials who are seeking input from library trustees about possible changes to the seawall and Harbor Park, in connection with the removal of the Montgomery Dam.

Library trustees have previously announced they will not endorse plans for the dam, but only proposed changes affecting Harbor Park.

Trustees and town officials walked through the park and discussed the area from the boundary at the Montgomery Dam to the boundary with the American Boathouse, according to Trustee Silvio Calabi.

Calabi said the group went over topics very thoroughly. Some things they learned about consequences of the dam and leaving or removing it should be of considerable interest to people of the town, Calabi said.

“At the end of the meeting we recommended to the town officials that they hold similar on-site sessions open to the public,” he said.

The library’s charge is to maintain and preserve Harbor Park, he explained. The trustees will have to look at changes to Harbor Park “in light of Mary Curtis Bok’s wishes, her covenant and the deed for the park,” he said.

But this does not mean leaving the present state of the park untouched, he said.

“The park is under threat from rising sea level,” he said. The prediction of 18 inches of sea level rise by 2050, which is now what State agencies are using, will have a significant impact on Harbor Park, he said.

“We’ve all seen the seawall covered by water,” he said. He explained that when water covers the wall and washes out again it takes some of the fill out and causes the wall to degrade. This situation will worsen, and calls for an evolution of the sea wall design, he explained, adding this has not yet been thoroughly discussed by the full board of trustees.

The group also talked about work planned by the Maine Department of Transportation to replace the Main Street Bridge over the Megunticook River in early 2024. Calabi said there is recognition that this will include opening the area under the bridge to improve flood run off. He said the group agrees decisions about Harbor Park and plans for Montgomery Dam should be firmed up before that construction.

Trustees are expecting from town officials a more detailed design for what the dam, harbor park and mouth of the river could look like. “We’ve told the Select Board that sooner is better,” he said.
