Guidelines for Historic Assessments
A historic assessment is a survey and evaluation that is used to determine the significance of a historic resource. The assessment contains a physical description of the historic resource as well as an evaluation of the property within its historic context.
Housing and Community Development Planning Services (HCD) will require an applicant to hire a qualified historic consultant who meets the Secretary of the Interior’s Professional Qualifications for Historian and/or Architectural Historian to prepare a Phase One Assessment when a project has the potential to adversely affect a building, site, object or structure over 50 years old. The assessment will determine if a resource is historically significant by using criteria from:
- National Register of Historic Places
- California Register of Historic Resources
- Monterey County’s Register of Historic Resources
The assessment should analyze the history and description of the property for each set of criteria to determine if it is eligible for listing on the above registers. As applicable, the assessment must evaluate the parcel’s potential to contribute to a historic district. A district is composed of a significant concentration of sites of buildings that convey a visual sense of the overall historic environment or an arrangement of historically or functionally related properties. Conclusions should be based on an objective analysis of the information presented in the assessment.
If it is determined that a resource is eligible for listing on one or more of the above registers, then a Phase Two Assessment is triggered.
A Phase Two Assessment will determine how a project will affect the significance of a resource. The Phase Two Assessment shall provide potential mitigation measures if applicable, for consideration by the County, to reduce impacts to a level of insignificance.
If the impact cannot be mitigated, a clear statement that the proposal will cause a significant impact to the resource which cannot be mitigated shall be included. Both the Phase One and Phase Two Assessments must be prepared by a qualified historic consultant. If a property is listed or has been determined eligible for listing on the National, California or Local Registers, then a Phase One assessment is not required and a Phase Two Assessment is automatically triggered for proposed development.
Uses of a Historic Assessment
A project that has been determined to conform to the Secretary of the Interior’s Standards for the Treatment of Historic Properties can generally be considered a project that will not cause a significant impact (14CCR § 15126.4(b)(1). In most cases if a project meets the Secretary of the Interior’s Standards for the Treatment of Historic Properties it can be considered categorically exempt from CEQA (14 CCR § 15331).
If a project does not conform to the Secretary of the Interior’s Treatment of Historic Properties HCD will use a historic assessment as a resource to complete an Initial Study (“IS”). The IS will determine whether a project will have a significant effect on a historic resource as required by the California Environmental Quality Act (“CEQA”), government Code Section 15300.2(f). A project will have a significant effect on a historic resource if it demolishes, or substantially alters a resource listed or eligible for listing on the National Register, California Register or Monterey County Register. If a project will not have a significant effect on the environment, the HCD will prepare a Negative Declaration for consideration and approval by the appropriate hearing body. If a project will have a significant effect on the environment, mitigation measures may be implemented to reduce the impacts to the resource to a level that is considered less than significant. HCD will then prepare a Mitigated Negative Declaration for consideration and approval by the appropriate hearing body. In the event that impacts are so great that mitigation measures cannot be implemented to reduce the impact to a less than significant level, HCD will require the preparation of an Environmental Impact Report (“EIR”).
