Cornerstone environmental consultants presented a Phase 2 cultural resource study on Nov. 19 for 418 South LaRue, a property the report treats as contributing to the Flagstaff Southside Historic District. The commission voted to accept the study and approved additional mitigation measures, with requested edits to the report and outreach to local community organizations.

Sam Hemsley of Cornerstone summarized the work: field visits, archival research, measured drawings, photographs and multiple LiDAR scans. Cornerstone recommended the primary bungalow (constructed c.1939 per city records) is significant under City of Flagstaff criteria A (previous determination), B (ethnic heritage/social history) and D (architecture) and eligible under National Register criterion A for its association with social and ethnic‑heritage themes in the Southside. The wooden auxiliary structure on the property was documented as degraded but may contribute to the site's significance for ethnic heritage.

As mitigation for demolition and redevelopment, Cornerstone proposed additional measured drawings and high‑resolution LiDAR and to assemble the documentation into an interactive 3‑D model for public access. Sam Hemsley said the firm would archive scans and provide the model to the City of Flagstaff for hosting and public interaction.

Commissioners asked for editorial corrections (photo captions and name formats), recommended adding Basque as a distinct community alongside references to Hispanic residents where appropriate, and suggested Cornerstone consult Southside neighborhood groups and local repositories (for example, NAU's collections) about archiving and oral‑history ties. One commissioner raised concerns about lead paint and asbestos precautions during eventual demolition; staff confirmed hazardous‑materials remediation and demo permitting will be handled through the appropriate city processes and code requirements.

Motion and vote: Commissioner Amy Horn moved to approve the Phase 2 report and the additional LiDAR documentation and to accept the interactive 3‑D mitigation measure; the motion required report edits and community consultation and authorized the heritage preservation officer to review minor edits administratively. The motion was seconded and commissioners voted in favor.

Next steps: Cornerstone will update the report with the requested edits, pursue outreach to Southside organizations and deliver the final scans and model to the city for archiving and public access. Hazardous‑materials remediation and the demolition permit remain separate processes administered through city permit channels.
