The Lewiston Planning Board on Monday night approved a new housing plan for the former Martel School in a 5-2 vote.

Avesta Housing Development Officer Catherine Elliott said Tuesday that Lewiston Housing Authority will own and manage the project and have retained Avesta to oversee and consult on the development process.

The $10.4 million project will develop 44 senior housing units, renovating the 1922 building and constructing a new three-story wing, according to the application.
