Storm Drainage

The storm drainage system in the community has been mapped. Most of the drainage water infiltrates the ground or ends up in the lakes. Flooding does not constitute a major problem in Mountain Lakes as it is a headwater area. Excessive rain storms will flood a number of basements. Run off problems have been identified in several areas and are being addressed with installation of additional catch basins and lateral connections. Ten detention or retention areas have been built in the Borough as part of residential and commercial developments. As a headwater area, the community should continue to take responsibility to provide zero increase in surface-water run off in connection with major developments for the benefit of the downstream communities. In addition, the Borough’s Surface Water Management regulations should provide for mitigation of pollution in storm water of such developments. The Borough also follows New Jersey Surface Water Management regulations, aggressively maintaining catch basins and lateral connections, replacing when necessary.
