American Institute of Architects (AIA)
Similar to APA’s CPAT, AIA’s Center for Communities by Design is the hub for pro-bono work.
The Regional and Urban Design Committee (RUDC) of the AIA aims to improve the quality of the regional and urban environment by promoting excellence in design, planning, and public policy in the built environment.
American Society of Landscape Architects (ASLA)
The Historic Preservation Professional Practice Network of the ASLA serves as a forum for landscape architects and their allied professionals to exchange knowledge and information in historic landscape preservation. Serving two primary functions, the network works to disseminate information to landscape architects working in historic preservation and to enhance communication among allied professionals and others interested in historic preservation.
The National Trust for Historic Preservation is a nonprofit that works to protect historic places. The National Trust works, in part, through its subsidiaries and affiliates, which include an investment corporation and an insurance agency.
Preservation Resources via the National Association of Preservation Commissions
The National Association of Preservation Commissions is a nonprofit founded to provide a forum for preservation commissions to discuss mutual problems and serve as a national voice for the particular needs of commissions.
