Re: Second Peer Review – 31526 Valido Road, Laguna Beach, California Dear Ms. Steven:
GPA Consulting (GPA) previously prepared a peer review of historic resource assessment reports for the property located at 31526 Valido Road in Laguna Beach, California. The initial assessment, prepared by Historic Resources Group (HRG) on behalf of the City, concluded that the property qualifies for listing in the California Register of Historical Resources (CRHR) under Criterion 1 due to its association with early homesteading and the Homestead Act of 1862. In response, the applicant retained Chronicle Heritage, which prepared a separate historic resource assessment concluding that the property does not qualify for listing due to insufficient integrity, particularly with respect to setting.
Due to these conflicting conclusions, the City engaged GPA to provide an independent, third-party peer review to evaluate whether the conclusions presented in the HRG report were adequately supported by the facts. GPA completed this initial peer review in July 2025, based on the following documents:
• Historic Resources Assessment, 31526 Valido Road, Laguna Beach (Historic Resources Group, February 12, 2025)
• Historic Assessment Supplemental Memorandum (Historic Resources Group, June 3, 2025) • Historic Resource Assessment of 31526 Valido Road, Laguna Beach 92651 (Chronicle Heritage, April 2025)
Subsequent to GPA’s initial peer review, the applicant’s request to demolish the existing residence and construct a new single-family dwelling was approved by the Design Review Board on September 25, 2025. That decision was appealed to the Laguna Beach City Council. In response to the appeal, additional materials were prepared and submitted to the City, including:
• Historic Resource Technical Memorandum (Environmental Science Associates [ESA], January 27, 2026)
• Response to Comments on Historic Resource Assessment (Historic Resources Group, March 23, 2026) In light of this expanded record, the City has requested that GPA conduct a second peer review of the newly submitted materials and prepare a memorandum with recommendations to City staff in advance of the appeal hearing. As part of this scope of work, GPA has reviewed the above-listed documents, in addition to public comments submitted in response to the proposed project, including correspondence from Ann Christoph, Landscape Architect, dated September 19, 2024, and correspondence from Greg O’Loughlin, President of the South Laguna Civic Association, dated July 24, 2022, which provide historical information and perspectives regarding the subject property. GPA’s review also incorporates the previously evaluated reports prepared by HRG and Chronicle Heritage.
Attachment 23

GPA’s role in this process is to provide an objective, non-biased evaluation of the adequacy of each report, with particular focus on the methodology, accuracy, completeness, and evidentiary support for the conclusions presented. GPA has not conducted a new historic resource assessment, site visit, or independent research.
Rather, this peer review is limited to an evaluation of the existing record to determine which conclusions are most appropriately supported by substantial evidence in light of applicable professional standards, including guidance set forth in National Register Bulletin 15 and the California Environmental Quality Act (CEQA).
Summary of Environmental Science Associates (ESA) Technical Memorandum Environmental Science Associates (ESA) prepared a Historic Resource Technical Memorandum dated January 27, 2026, at the request of the property owner in response to the appeal of the Design Review Board’s approval of the proposed project. The memorandum includes a review of previously prepared historic resource assessments, including those by Historic Resources Group (HRG), Chronicle Heritage, and GPA’s prior peer review, as well as supplemental research utilizing archival sources such as historical aerials, property records, and regional historical documentation. ESA also conducted a site visit of the subject property on October 29, 2025. The evaluation was prepared by a qualified architectural historian in accordance with the Secretary of the Interior’s Professional Qualification Standards and applicable federal, state, and local regulatory frameworks, including the National Register of Historic Places (NRHP), the CRHR, and the City of Laguna Beach Historic Preservation Ordinance.
ESA concludes that the subject property does not meet the eligibility criteria for listing in the California Register of Historical Resources (CRHR) or the National Register of Historic Places (NRHP) and therefore does not qualify as a historical resource under CEQA. This conclusion is consistent with GPA’s prior peer review and is based on the determination that, while the property is associated with early homesteading activity, it does not rise to the level of significance required under applicable criteria. ESA further finds that the property does not retain sufficient integrity to convey its historical significance, particularly in light of changes to the surrounding context.
The memorandum also notes that the physical condition of the structure is poor and that rehabilitation for continued residential use would likely require substantial alterations that could affect remaining characterdefining features. While ESA acknowledges that the property may have some local historical interest as an early residence associated with rural development in South Laguna, it concludes that this does not meet the threshold for eligibility under the CRHR or NRHP criteria.
Although ESA determines that the property is not a historical resource under CEQA, the memorandum recommends several measures to document and interpret the site’s history, including preparation of Historic American Buildings Survey (HABS)-level documentation, installation of an interpretive historical marker, potential relocation of the original portion of the residence for interpretive purposes, and, if relocation is not feasible, the salvage and donation of character-defining materials. These recommendations are presented as measures to preserve historical information rather than as support for eligibility.
Summary of Historic Resources Group (HRG) Response to GPA Peer Review Historic Resources Group (HRG) prepared a Response to Peer Review Memorandum dated March 23, 2026, in response to GPA’s July 2025 peer review of the historic resource assessments for the property at 31526 Valido Road. The memorandum is focused on addressing GPA’s conclusion that insufficient evidence was presented to support eligibility of the subject property for listing in the CRHR or the NRHP. HRG does not dispute GPA’s findings regarding methodology or research adequacy, but instead challenges GPA’s interpretation of the evidence, particularly with respect to historic context, rarity, comparative analysis, and integrity.
In response, HRG presents additional research intended to strengthen its original conclusion that the property is eligible under CRHR Criterion 1 and NRHP Criterion A at the local level. HRG expands its historic context to include “Homesteading in Orange County,” providing broader regional background on land ownership patterns, settlement limitations, and the relative scarcity of successful homesteads due to the dominance of large private landholdings and railroad-controlled lands. Based on this expanded research, HRG asserts that the Egan Homestead is a rare resource, potentially representing the only surviving homestead residence in Orange County 645
that retains integrity and association with its original use. HRG also responds to prior concerns regarding the lack of comparative analysis by arguing that comparable properties no longer exist or have been significantly altered or relocated and therefore do not retain sufficient integrity for meaningful comparison.
HRG further addresses the issue of integrity, acknowledging that the property has experienced a loss of historic setting but maintaining that sufficient integrity remains in other aspects, including location, design, materials, workmanship, feeling, and association. The response emphasizes that a property does not need to retain all seven aspects of integrity to be eligible and cites guidance supporting a flexible and context-driven evaluation of integrity. HRG also introduces the argument that adjacent preserved open space, including the Laguna Greenbelt and surrounding wilderness areas, provides a visual and environmental context that continues to convey aspects of the property’s historic setting despite surrounding residential development. In addition, HRG expands its discussion of the Homestead Act, emphasizing its long-term role in shaping settlement patterns in the American West and reinforcing the relevance of the property’s period of significance within this broader historical framework.
Based on this expanded analysis, HRG maintains that the subject property meets the eligibility criteria for listing in the CRHR and NRHP at the local level, asserting that its rarity, historical associations, and retained integrity collectively support its significance as a representative example of early homesteading in the region.
Summary of Public Comments
GPA reviewed public correspondence submitted to the City regarding the subject property, including letters from members of the public and local organizations.
A letter dated September 19, 2024, from Ann Christoph, a landscape architect, asserts that the residence was constructed in association with the Egan family’s 1910 homestead and characterizes the property as the oldest house in South Laguna and potentially the last remaining homestead residence in Laguna Beach. The letter expresses concern that the property’s potential historic significance was not clearly identified in project materials and supports further consideration of its historic status.
Additionally, correspondence dated July 24, 2022, from Greg O’Loughlin, President of the South Laguna Civic Association, describes the property as a historically significant homestead associated with early settlement patterns in South Laguna. The letter references the Egan family’s 40-acre homestead claim, early agricultural use of the site, and the property’s association with broader patterns of homesteading in the area. The correspondence asserts that the property may qualify as a historic resource and advocates for its preservation.
Peer Review Analysis – Environmental Science Associates (ESA) Environmental Science Associates’ (ESA) Historic Resource Technical Memorandum (January 27, 2026) provides a clear and professionally consistent evaluation of the subject property in accordance with applicable federal and state criteria and CEQA guidelines. ESA demonstrates a sound understanding of the distinction between historical association and historical significance and appropriately applies this framework in concluding that the property does not meet the eligibility threshold under Criterion A/1. The memorandum is generally consistent with GPA’s prior peer review, reinforcing the conclusion that association with early homesteading activity, without a clear demonstration of importance within a defined historic context, is insufficient to establish significance. ESA also appropriately recognizes that while the property may have local historical interest, this does not rise to the level required for listing in the CRHR or NRHP.
ESA’s conclusions regarding integrity are also generally consistent with prior findings, particularly with respect to the diminished integrity of setting and the resulting impact on the property’s ability to convey its historical associations. While ESA does not present a detailed, aspect-by-aspect integrity analysis, its conclusions align with the interpretation that the loss of the surrounding agricultural context limits the property’s ability to communicate its significance under Criterion A. The memorandum also introduces consideration of the current physical condition of the structure, noting that substantial rehabilitation would likely be required, which could 646
further affect remaining character-defining features. Although this observation is not determinative of eligibility, it provides relevant context regarding the property’s integrity and long-term preservation potential.
However, ESA’s analysis is largely confirmatory in nature and relies heavily on previously prepared reports rather than substantially expanding the evidentiary record. The memorandum does not include a robust comparative analysis of similar homestead properties within Orange County or the broader region, which would strengthen its conclusions regarding the property’s relative significance. Additionally, ESA does not directly engage with HRG’s argument that the property’s rarity may elevate its significance, leaving this key issue largely unaddressed. A more explicit evaluation of rarity in relation to established significance thresholds, as well as a more detailed articulation of the integrity analysis, would improve the overall defensibility of the conclusions.
Overall, ESA’s memorandum provides a well-reasoned and professionally grounded evaluation that supports the conclusion that the property does not meet eligibility criteria for listing in the CRHR or NRHP. While the analysis would benefit from additional depth in certain areas, it is consistent with accepted standards and reinforces the distinction between historical association and demonstrated historical significance.
Peer Review Analysis – Historic Resources Group (HRG) Response HRG’s Response to Peer Review Memorandum (March 23, 2026) provides a more detailed and focused argument in support of the property’s eligibility and directly addresses several issues raised in GPA’s prior peer review. The response strengthens the original analysis by expanding the historic context to include “Homesteading in Orange County,” offering additional background on regional settlement patterns, land availability, and the relative rarity of successful homesteads. HRG also presents new research intended to support its position that the subject property may represent a rare surviving example of a homestead residence in Orange County and attempts to address prior concerns regarding the lack of comparative analysis by asserting that few, if any, comparable properties remain that retain sufficient integrity. In addition, HRG appropriately reiterates that a property need not retain all seven aspects of integrity to be eligible for listing and emphasizes that the subject property retains integrity of location, design, materials, workmanship, feeling, and association.
The response further introduces the argument that adjacent preserved open space contributes to the property’s ability to convey aspects of its historic setting.
While HRG’s response represents a meaningful expansion of the original analysis and demonstrates a good-faith effort to address prior comments, several key issues remain insufficiently resolved. Although the argument for rarity is more fully developed, the response does not clearly establish that rarity alone rises to the level of historical significance as required under National Register Bulletin 15. The analysis does not demonstrate that the property is among the most important or illustrative examples of the identified historic context, and the comparative framework remains largely inferential, relying on the absence of comparable properties rather than a documented evaluation of similar resources within a defined geographic and thematic scope.
Additionally, while HRG acknowledges the diminished integrity of setting, the response does not fully resolve whether the loss of the surrounding agricultural context materially affects the property’s ability to convey its significance under Criterion A/1. The assertion that adjacent preserved open space provides a sufficient environmental context is noted; however, the analysis does not clearly demonstrate that this open space reflects the property’s historic agricultural use, as opposed to a broader natural landscape that is not directly tied to the property’s period of significance. Similarly, although the expanded regional context provides useful background, the response does not clearly establish how the subject property stands out within this broader context in a manner that meets the threshold for significance. As in the original report, key conclusions regarding integrity and significance remain interpretive and do not fully resolve the differing interpretations identified in prior reviews.
Overall, HRG’s response provides additional context and supporting information that is relevant to the evaluation of the property and strengthens certain aspects of the original argument. However, the response does not fully address the core issues identified in GPA’s prior peer review, particularly with respect to the relationship between 647
rarity and significance, the adequacy of comparative analysis, and the impact of diminished integrity of setting on the property’s ability to convey significance under applicable criteria.
Conclusion and Recommendations
Based on GPA’s review of the expanded record, including the Historic Resource Technical Memorandum prepared by Environmental Science Associates (ESA), the Response to Peer Review Memorandum prepared by Historic Resources Group (HRG), previously submitted historic resource assessments, and public comments, GPA finds that the evidence does not sufficiently support a conclusion that the subject property meets the eligibility criteria for listing in the CRHR or the NRHP.
Both ESA and HRG present arguments grounded in accepted professional standards; however, ESA’s conclusions are more consistently supported by the available evidence and more closely aligned with the evaluative framework set forth in National Register Bulletin 15 and related guidance. ESA appropriately distinguishes between historical association and demonstrated historical significance and concludes that, while the property is associated with early homesteading activity in South Laguna, this association alone is insufficient to establish eligibility without a clear showing that the property is an important or representative example within a defined historic context.
HRG’s response provides a meaningful expansion of the original analysis, particularly with respect to the development of a broader historic context and the argument for rarity. However, while the additional research strengthens the narrative surrounding homesteading in Orange County, it does not conclusively demonstrate that the subject property rises to the level of significance required under applicable criteria. In particular, the relationship between rarity and significance remains insufficiently substantiated, and the comparative framework continues to rely on the absence of comparable properties rather than a demonstrated evaluation of relative importance within a defined context.
Additionally, while HRG maintains that the property retains sufficient integrity to convey its significance, the loss of the historic agricultural setting remains a critical factor in evaluating the property under Criterion A/1. The available evidence does not clearly demonstrate that the property retains the necessary physical and contextual characteristics to effectively convey its association with early homesteading in a manner that meets established thresholds for eligibility. For instance, Laguna Beach is known for its early cottage construction as second homes or as artists’ residences; the construction style, form, and techniques for properties constructed under this context is similar to the Egan property, but significant properties under this context would not require the setting to be intact to interpret its significance as an early beach cottage or its association with a particular artist.
However, for a property to convey its association under a broad context such as homesteading, the setting is critical to conveying that significance, especially in light of the fact that it was established as a rural agricultural property and not simply a second beach home. Without even a partial surrounding rural or agricultural setting, the Egan residence does not clearly convey its association with the Homestead Act any more than it could be confused as an early beach cottage. This is why the setting of this particular property is imperative in demonstrating its association with Homesteading. Regardless of the argument of a loss of integrity, the property was not clearly demonstrated to be significant within the context that it was identified. As stated in GPA’s previous review, this property would be better identified simply as one of the earliest examples of pioneering residences within the South Laguna area (without its tie to the Homestead Act) under the City’s local ordinance.
Accordingly, GPA concludes that the subject property does not meet the criteria for listing in the CRHR or NRHP and does not qualify as a historical resource under CEQA. While the property may possess local historical interest, particularly as an early residence associated with the development of South Laguna, the available evidence does not support a finding of historical significance at the level required for designation under state or federal criteria.
However, in light of the entire record, should the City wish to further explore potential recognition at the local level, additional evaluation under a more narrowly defined local context may be warranted, subject to applicable provisions of the City’s Historic Preservation Ordinance. 648
Notwithstanding the conclusions above, GPA notes that under the California Environmental Quality Act (CEQA), a resource need not be formally listed in, or determined eligible for, the California Register of Historical Resources to be treated as a historical resource for purposes of environmental review. Pursuant to CEQA Guidelines Section 15064.5(a)(4), a lead agency may determine that a property is a historical resource if it is supported by substantial evidence in light of the whole record, including professional evaluations and public input. In this case, while GPA finds that the available evidence does not support eligibility for listing in the California or National Registers, the record does include professional and public assertions that the property may have local historical importance as one of the earliest residences associated with the development of South Laguna. As such, the City, in its role as lead agency, retains the discretion to determine whether the property should be treated as a historical resource for purposes of CEQA.
If the City elects to treat the property as a historical resource, it may also consider the implementation of appropriate measures to reduce potential impacts, consistent with CEQA Guidelines Sections 15064.5(b) and 15126.4(b), which address the treatment of historical resources and the development of feasible mitigation measures. Such measures may include documentation, interpretation, or other preservation-oriented strategies, similar to those recommended by ESA. However, CEQA requires that mitigation measures be roughly proportional to the level of impact, and mitigation is only required where a project would result in a significant impact to a historical resource. Accordingly, any consideration of mitigation should be commensurate with the degree of significance attributed to the resource and the severity of the potential impact.
