Nominations are sought for the Cambridge Preservation Awards program coming in May to honor historical preservation projects started and finished with the past calendar year. Residents and property owners, neighbors and visitors, architects and contractors are invited to nominate projects that contribute to the preservation of Cambridge’s historic character and its built environment. Projects can involve restoration, rehabilitation, adaptive use, neighborhood conservation, landscape preservation, archaeology or preservation education, and may involve private homes, institutional buildings or commercial and industrial properties.

“This is an excellent opportunity to give credit to property owners and community members who exemplify good stewardship and promote the broader benefits of historic preservation,” Cambridge Historical Commission officials said in a press release.

Such projects have been celebrated by the commission annually since 1997.

Nomination forms and information on the preservation recognition program are available at commission offices at 831 Massachusetts Ave.; on its website; or by calling (617) 349-4683. Nominations must be submitted by noon Feb. 22.
