The eighth annual Preservation Awards will be presented by the New Canaan Preservation Alliance at a reception on May 3 at the New Canaan Country Club. Selected by a jury of preservationists and board members of the Alliance, the winners will be presented certificates of honor. There are three categories of winners: the Committee's Award for Preserving a Sense of Place, the Trustees' Award for Rehabilitation and the President's Award for Preservation. The reception will begin at 4 p.m. Historian, architectural consultant and author Rachel Carley will then give a brief overview of her research for the Alliance, funded by a grant from the State Historic Preservation Office, with funds from the Community Investment Act. Carley has been studying the properties surrounding the downtown area and analyzing the development and subdivisions of the town from its earliest days through its suburbanization in the 1920s. Presentation of awards will follow her talk. This year, there are five awards, for residences ranging from an 18th century saltbox to a 1954 Tech Built house. A sixth award, for community service, will be presented to a New Canaan resident who has made a recent significant contribution to the preservation of the town's heritage. Reservations are requested on the NCPA website, www.newcanaanpreservatioinalliance.org or by calling the president, Rose Scott Long, at 966-7671. Admission is free.
