Criteria for Alterations of Class 1 Historic Resources
Criterion 1: That the proposed alteration does not significantly impact or materially impair the character-
defining features of the historic resource as listed in the resolution for historic designation, or, where a
character-defining feature may be impacted, the proposed alteration minimizes that impact as much as
possible;
Criterion 2: That the proposed alteration will assist in restoring the historic resource to its original
appearance where applicable, or will substantially aid its preservation or enhancement as a historic
resource;
Criterion 3: That any additions to the historic resource are consistent with the massing, proportions,
materials, and finishes of the existing historic resource, and: (i) can be distinguished from the existing
historic resource as may be appropriate; or (ii) are indistinguishable from the historic resource as may be
appropriate, and where such alterations are clearly documented in the City’s archival file for the historic
resource as being non-original to the historic resource;
Criterion 4: That, in cases where Federal funds are to be utilized in financing the proposed alterations, the
alterations are consistent with the Standards for the Treatment of Historic Properties, as put forth by the
U.S. Secretary of the Interior.
Conclusion
The proposed scope of work does not materially impair or negatively impact the character-defining features of the
historic site. The proposed single-family home is adequately distanced from the new construction and the
maintenance of the historic ruin is the responsibility of the owner in accordance with the conditions for historic
designation. Staff finds that all required criteria for the Certificate of Appropriateness are met with the proposed
conditions of approval.
Recommendation
Staff recommends the HSPB approve the Certificate of Appropriateness with conditions:
1. Environmental monitors required during the grading phase of the project,
2. Provide a “long-term maintenance plan” for the historic resource,
3. Preservation/conservation treatment of existing ruins, and
4. Amend Mills Act Agreement.
Any significant changes to the proposal must be re-evaluated for compliance with the criteria for alteration.
