Building, Zoning, Engineering

The Borough Engineer is required to be a licensed professional engineer in the state of New Jersey. Appointed by the Mayor and Council, the engineer provides technical services to many other Borough Departments and to municipal boards such as the Planning Board. State law requires that municipal infrastructure improvements such as roads, sewers, culverts, etc., be designed by a licensed professional engineer. Some of the duties of the Borough Engineer include review and inspection of drywells and storm water systems, review of retaining wall designs, review of Planning Board and Zoning Board of Adjustment site plans, municipal infrastructure improvements, and review all zoning calculations sheets for compliance with state and local resolutions. Any additions to homes or other buildings must first be reviewed and approved by the Borough Engineer for Zoning Compliance prior to obtaining a construction permit. Meetings with the Borough Engineer can be arranged by calling Public Works.

 Click on the SDL Portal Icon above. Choose from 3 different dates and the first available date will be given to you. Please keep in mind that your first choice may not be available. First time users will need to create a username and password. 

Once you have created an account, you will be able to Navigate the site by searching  Address, Block, Lot and Permit Number.  While looking up property information, we have found the best way is by entering the least amount of information as possible. For example if looking up 1385 Route 22 West – Try simply entering 1385 Rou.
