City to replace roof and correct ventilation after dorm air-quality assessment finds mold linked to moisture

City officials told the council on Aug. 11 that an independent air-quality assessment of a dormitory annex found no evidence of so-called “black mold” but did detect routine indoor/outdoor mold types and elevated moisture in one bedroom. The assessment concluded excessive moisture — not toxic mold — is the root cause. The city outlined planned corrective steps: replace the roof and siding, install a moisture‑resistant wrap before re-siding, route bathroom vents properly through the roof, and consider installing a dehumidifier. After structural fixes are completed, the city will hire a certified contractor to clean and mitigate the areas identified in the assessment. Why it matters: City officials said the work is intended to address the moisture source and reduce occupant exposure. Council members asked whether the city’s insurance would cover repair costs; administration reported that the insurer declined coverage, citing moisture rather than a covered sudden event and the absence of highly toxic mold types in the assessment. Details: The safety director introduced the department’s report and turned the update to Chief Chasco, who summarized the air-quality testing. He said one bedroom showed higher moisture than other parts of the building and that planned repairs include improved venting and a moisture barrier installed under new siding. The administration will obtain quotes for structural repairs and for certification-level cleaning and mitigation once repairs are complete. Next steps: The administration will proceed to put the repairs out for bid or schedule work through the city’s service department and will provide further information on funding and timing at a future meeting. Council members requested that staff confirm the insurer’s denial in writing and return with cost estimates and a firm timeline for repairs and remediation.
