The Hot Springs Board of Directors approved an agreement Tuesday night that would provide $750,000 in federal funds to turn an old Park Avenue motel into affordable housing for artists. The city recommended Bellaire Apartments, 637 Park Ave., for the $750,000 National Park Service Paul Bruhn Historic Revitalization Grant. The boarded up and vacant building was one of seven applicants for funding from the program, which the city joined to help expand low- to moderate-income housing.
