From the Cambridge Historical Commission, July 5, 2017: Members and alternate members are sought to fill vacancies on the Avon Hill Neighborhood Conservation District Commission, Half Crown-Marsh NCD Commission and Mid-Cambridge NCD Commission. The deadline for submitting applications is Aug. 14.

Neighborhood Conservation Districts were established by city law beginning in 1983. The designation recognizes the particular design qualities of distinctive neighborhoods and encourages their protection and maintenance for the benefit of the city. The three NCD commissions in Cambridge each include five members and three alternates, supported by the professional staff of the Historical Commission.

Most members must be residents of the neighborhoods. (Information and maps of the Avon Hill, Half Crown-Marsh, and Mid-Cambridge NCDs are available at cambridgema.gov/DistrictMaps.) Applicants should have an interest in architecture, local history or neighborhood preservation; be committed to protecting the historic resources and built environment of the city; and be able to meet monthly. Appointments to the commission are made by the city manager with regard to a diversity of viewpoints. Minority candidates are particularly encouraged to apply.

People interested in being considered should apply by using the city’s online application system at cambridgema.gov/apply. A cover letter and résumé or summary of applicable experience can be submitted during the online application process. Paper applications are available in the City Manager’s Office at City Hall, 795 Massachusetts Ave., Central Square.
