Attention Property Owners:

During the week beginning May 26th, representatives of Aqualis, the Borough's stormwater management contractor, will be conducting field work to collect stormwater asset data using high accuracy GPS units to complete work required under the New Jersey Department of Environmental Protection (NJDEP) Tier A MS4 Municipal Stormwater Program. Field workers may need to briefly enter your property to identify stormwater features in the course of this data collection work.
