As Dartmouth residents wait in line to get their beach stickers they may notice a letter from the Parks and Recreation Board provided along with it.

On Monday the department opened its doors at 9 a.m. to begin selling stickers. However, along with a beach sticker this year residents will also receive a noter from the Parks Board explaining their continued efforts to keep Round Hill Beach clean and accessible to the community.

The letter states normal beach maintenance has been halted after a group calling itself “Advocates for Coastal Resource Protection” sent a note to state officials complaining about the machinery used to rake the beach of hazardous materials. Now, lifeguards will search the beach before it opens and remove any dangerous materials.

At a March 26 meeting the board discussed using prisoners to clean the beach, but the details on whether it can happen are still being worked out, according to Parks Director Tim Lancaster. Lancaster said the board doesn’t want to get anyone’s hopes up with the idea when nothing has been settled on.

Lancaster meet with state officials, Senator Mark Montigny (D-New Bedford) and Representative Chris Markey (D-Dartmouth) on May 7 to discuss the next step in resolving the issue, although no update was received.

Beach stickers are on sale Monday through Friday from 9 a.m. to 4 p.m. at the Parks Board office at Town Hall. Town Hall is located at 400 Slocum Road.
