ROCKLAND — The road serving the Midcoast Habitat for Humanity housing development on Talbot Avenue is under construction.

The project received final approval from the Rockland Planning Board on May 17.

Habitat plans to build 13 residences on the 10.6-acre lot. The first phase will be the six 500-square-foot homes to be managed by the Knox County Homeless Coalition. The second phase will be two duplexes, also to be managed by the Homeless Coalition. The two-bedroom units will be 900 square feet and the three-bedroom units 1,100 square feet.

The final phase would be the three Habitat homes of 900 square feet.

Most of the lot will remain undeveloped.

The organization will need to get approval from the wastewater plant director before it can connect into the city’s sewer system. Habitat Executive Director Tia Anderson said earlier this year the organization has the money to pay for separating the stormwater and sewer lines in the adjacent neighborhood. The cost is estimated at $200,000. She said the city was looking to apply for a grant to help pay for that separation.
