A. The Neighborhood Conservation Combining District
The City of Austin Neighborhood Conservation Combining District (NCCD)
(Ordinance No. 020131-20) already regulates the modification and construction
of buildings and other structures in Hyde Park. It also provides for standards that
affect fences, driveways, accessory buildings, garages, maximum building
coverage, maximum impervious cover, maximum height, setbacks, and building
facades, among other things. In no case shall the standards established by the
NCCD be invalidated by any additional standards; they may, however, be
narrowed by additional standards in order to ensure compatibility with the historic
patterns of the Hyde Park neighborhood, an issue which is not addressed by the
NCCD.
B. The Secretary of the Interior’s Standards for the Treatment of
Historic Properties
This Preservation Plan adopts The Secretary of the Interior’s Standards for the
Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating,
Restoring & Reconstructing Historic Buildings (by Kay D. Weeks and Anne E.
Grimmer, 1995, U.S. Department of the Interior). This document provides
detailed descriptions and instructions for preservation, rehabilitation, restoration,
and reconstruction of historic structures.
Basic standards for rehabilitation were developed in 1976 and are as follows:
A property shall be used for its historic purpose or be placed in a new use that
requires minimal change to the defining characteristics of the building and its
site and environment.
The historic character of a property shall be retained and preserved. The
removal of historic materials or alteration of features and spaces that
characterize a property shall be avoided.
Each property shall be recognized as a physical record of its time, place, and
use. Changes that create a false sense of historical development, such as
adding conjectural features or architectural elements from other buildings,
shall not be undertaken.
Most properties change over time; those changes that have acquired historic
significance in their own right shall be retained and preserved.
Distinctive features, finishes, and construction techniques or examples of
craftsmanship that characterize a historic property shall be preserved.
Deteriorated historic features, finishes, and construction techniques or
examples of craftsmanship that characterize a historic property shall be
preserved.
Chemical or physical treatments such as sandblasting that cause damage to
historic materials shall not be used. The surface cleaning of structures, if
appropriate, shall be undertaken using the gentlest means possible.
Significant archeological resources affected by a project shall be protected
and preserved. If such resources must be disturbed, mitigation measures
shall be undertaken.
