Property Summary

Moderate Compound Flood Exposure index. Groundwater flooding is the primary exposure factor for this property. Moderate infiltration potential — standard systems such as drywells and French drains are viable. Estimated groundwater depth of about 7' 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 buried historic streams and ponds — groundwater levels may rise rapidly during rain events independent of the resting water table depth; subsurface investigation is recommended before any infiltration work.
