As part of its preservation advocacy work, the Chestnut Hill Conservancy maintains a Historic District Advisory Committee (HDAC) composed of preservation, architecture, planning and development professionals. The HDAC addresses issues raised during the community’s design review process reviewing projects that are related to historic structures, properties, and open space for their effect on the character of the Chestnut Hill National Register Historic District. The boundaries of this District roughly correlate to the 19118 zip code in the City of Philadelphia. The HDAC has been the Chestnut Hill Conservancy’s agent as a Recognized Community Organization since 2015.
The Conservancy evaluates variance requests based on the Secretary of the Interior’s Standards for Treatment of Historic Properties, and Philadelphia’s Zoning Board of Adjustment’s (ZBA’s) criteria for zoning variances, as described in this link to the ZBA Application for Appeal.
