“Flood Depth Hazard Maps”

image_pdfimage_print

Maps are broken down into 4 parts.

(1) is “Action Level”, where we begin to see effects of flooding and prepare to take action (Ie: flood buster pumps, flood gates).

(2) is “Minor Level”, where we see minor flooding in our low lying areas.

(3) is “Moderate Level”, where more streets that aren’t typically covered get flooding.

(4) is “Major Level”, where flood water reaches depths that begin to damage property and vehicles.
