Gorham planners Monday, after a quieter second public hearing, delayed an ordinance-change decision impacting an industrial development.

But the Gorham Planning Board is expected to vote this month on its recommendations to the town council for proposed amendments to the land-use code. Timing of the proposed changes – coming while the planning board is considering a request by Shaw Brothers Construction Inc. for a quarry and asphalt plant – is being criticized by opponents.

Some 50 people were on hand July 30 when planners also heard public comment. The board has scheduled another hearing for Monday, Aug. 20, before it votes. The board will meet in the municipal building, 75 South St., but a time hadn’t been announced by Tuesday.

Shaw Brothers Construction Inc. is proposing a multi-million-asphalt plant and quarry on 125 acres it purchased from Lachance Brick Co. The brick company retained a few acres and buildings to sell bricks. The site is zoned industrial. The asphalt plant and quarry would require permits from the Maine Department of Environmental Protection.

The town council sent a proposal in July to the planning board to amend ordinances for review and recommendation. Changes cover noise standards; allowing an abutter to waive noise standards, if exceeded; the angle of slopes on quarry sides; and quarry operating times. The town council likely will consider the ordinance amendments at its meeting on Tuesday, Sept. 4.

“Several council members asked staff to review the need to clean up the language on noise and slope issues and it became apparent that the language in our ordinance was intended to deal with gravel pits instead of a rock quarry,” Town Manager David Cole said last week. “I believe that Shaw Brothers asked for one change, which would allow them to move the location of the asphalt plant farther away from neighbors in order to reduce the potential impact to the neighbors. If my memory is correct, I believe the council generally agreed that reducing any potential impact on abutting neighbors would be beneficial,” Cole said.

In contrast to the first hearing, only three opponents to the proposed ordinance changes spoke. One, Jennifer Everett, Libby Avenue, said that changes now are inappropriate. “Just because (ordinance changes) have been done before doesn’t make it right,” Everett said.

In other action Monday, the planning board approved 5-0 (Tom Fickett abstained and Mark Stelmack absent) a mobile vending unit requested by Howard Ross to sell coffee, muffins and hot dogs at White Rock Outboard, Sebago Lake Road.

“I’ve never seen a hot dog stand make much noise,” Ross joked.

The planning board also granted preliminary approval to Olde Canal Business Park, proposed by Grondin Properties, LLC., off Mosher Road.

Plans call for a nine-lot commercial/industrial park on 56 acres zoned industrial. The property is served by public water, sewer and gas. Engineer Owens McCullough of Sebago Technics said Grondin has interested parties for lots. “One is ready to submit a site plan,” McCullough said.

McCullough expected approval from the Maine Department of Environmental Protection for the project within two weeks.
