ROCKLAND — What’s coming down along the city’s south end waterfront — and what will go up in its place — has some neighbors concerned and calling for more disclosure.

MBNA New England announced earlier this year it would purchase the Douglas Dynamics property to become the site of its newest office, where 1,000 people will be employed. The property included about 10 houses and several industrial buildings where Fisher plows were manufactured. Douglas has moved to a new building about a mile away from the downtown.

That MBNA planned to build new offices on the property is no surprise. But the company has not yet revealed what form those buildings will take, and whether all the structures — including some which neighbors believe are historically valuable — will come down.

When the purchase of the property was first announced, MBNA officials promised to issue a comprehensive plan for the development of the property by mid-summer. But the active demolition work begun last week has prompted questions, and launched more than a few rumors.

Lizzie Dickerson, who works at the Good Tern Food Co-op across the street from the new MBNA property, is circulating a letter calling for people to attend Monday night’s City Council meeting to ask to be involved in the planing process.

“Right now, in our city, anyone can demolish property without submitting a plan,” Dickerson wrote. “It’s one thing when it’s the average homeowner pulling down an old garage. It’s quite another thing when a major corporation pulls down an entire neighborhood.”

MBNA spokesman David Spartin said Thursday the plan for the property is still being developed and will be made available when it is completed.

Dickerson claims many of the homes may qualify for registration with the National Historic Trust.

The so-called Snow mansion, a Greek Revival house that faces the water, as well as houses at 201 South Main St. and 17 Water St. are houses that were owned by Douglas Dynamics and conveyed to MBNA in the purchase. These three are “historically significant,” Dickerson said Earle Shettleworth of the Maine Historic Preservation Commission told her.

Dickerson has also been in contact with representatives of the National Historic Preservation Trust, and Maine Preservation, a group based in Portland.

MBNA has assisted the occupants of the houses, many of whom were on week-to-week leases, with relocating, Spartin said.

Shane Flynn, who runs the company’s operations in the Northeast, said Friday there are no firm plans for the property. Reports that the Snow house would be moved are unfounded, he said, because no decision has been made.

Rumors that MBNA was seeking to purchase town-owned land along the waterfront, and was asking to close off a street, are also untrue, Spartin said.

Becky Dow of the city’s code enforcement office said Friday demolition is permitted as long as utilities are properly disconnected. No plans for replacement buildings are required.

The MBNA property falls into three different zones, she said, and office buildings are permitted on the bulk of the land.

But Dickerson believes the size and scope of what MBNA plans — employing 1,000 people — should trigger more municipal oversight at this juncture.

“I think our city government should be taking a much more active role in this,” she said.
