The City Council on Wednesday authorized the city manager to enter into a contract with Sangerville-based Gordon Contracting Inc. to rebuild the south-facing retaining wall at Hamlin Park. A site evaluation report earlier this year found that multiple granite blocks have been dislodged from the lower portion of the wall between Central and Hammond streets and that plant growth is widening gaps between the stones.
