1. Regional Microclimate Dynamics & Severe Storm Exposure in Eagle Storm Damage
Eagle's geographic position between the Boise River basin and the rugged Boise Foothills creates unique microclimate dynamics. Properties on elevated foothill parcels experience severe downslope winds that swirl around complex multi-level roof hips and valleys. During winter inversions, heavy snowdrifts accumulate behind masonry chimneys exceeding 30 to 48 inches in width. When warming afternoon sun melts these snowdrifts, water pools behind inadequately flashed chimneys and seeps beneath clay or concrete tiles, soaking wood roof batten systems and ceiling drywall below.
