DC Zoning Review
Historic Structures Working Group
DC Office of Planning
Meeting 1
March 13, 2008
Background:
Historical preservation procedure
The Zoning Regulations do not address
issues related to historic preservation in any
one chapter or zone district.
Historic preservation is enforced through
the Historic Preservation Review Board
(HPRB), aided by the technical expertise of
the Historic Preservation Office (HPO) within
the Office of Planning. The District has in
excess of 25,000 historic properties and 27
historic neighborhoods, and it is only these
properties that fall within the jurisdiction of
the HPRB.
The zoning for these properties, including
use, bulk regulations, and parking and
loading requirements, is controlled by the
Zoning Regulations. With the exception of
use, implementation of these zoning
provisions may be modified by the HPRB,
although not always in conformance with
the Zoning Regulations, requiring further
relief from the Board of Zoning Adjustment.
Purpose of the Historic
Structures Working Group
The goal of the Office of
Planning and the Zoning Review
Task Force is to make the Zoning
Regulations more “user friendly”
and preservation-oriented, as
needed, to ensure that the goals
and guidelines of the HPRB and
HPO are more easily attained.

Other Issues
“Buffer Zones” and Conservation
Districts
Buffer zones
Some jurisdictions have created “buffer zones” around historic
districts to protect the edges of those historic districts from
inappropriate intrusions such as cell phone towers and antennas,
or other visual intrusions.
Conservation Districts
Another tool used by some jurisdictions is the designation of
conservation districts. Conservation districts achieve preservation
ends at a neighborhood scale without some of the perceived
burdens of a traditional historic district. Conservation districts are
typically established in lieu of - rather than in addition to - historic
districts to protect special historic, architectural or cultural
character.
