This parcel was previously disturbed as part of the construction associated with 40 Eagle Ridge Way. Currently there is a stormwater management plan for 40 Eagle Ridge Way approved by the West Orange Planning Board. That plan does not consider the disturbance at 42 Eagle Ridge Way. Should this plan not be approved the Storm Water Management Plan for 40 Eagle Ridge Way must be revised.
