Property Summary
High Compound Flood Exposure index.Stormwater flooding is the primary exposure factor for this property.Low infiltration potential — conveyance and management strategies may be more appropriate. Estimated groundwater depth of about 4' indicates a persistently shallow water table with elevated seepage potential into below-grade spaces. Property drains to the BB-029 combined sewer outfall. Site overlaps a buried historic stream — groundwater levels may rise rapidly during rain events independent of the resting water table depth; subsurface investigation is recommended before any infiltration work.
