33	A large portion of Bouond Brook is protected by the flood reduction project. Pump station operations become critical, at this stage, for the continued protection of the borough.
30	Main Street is protected by flap valves/sluice gates. This level triggers the gate closures to protect Main Street.
28	Backyard and low areas are protected by levees and the flood wall. Without the levees or if there is a breach in the levees, minor flooding will occur.
