Engineering Division


Effective January 1, 2017, the fee schedules for the Department of Planning & Development were updated. For many years the fees have remained unchanged despite continually increasing expenses. The updated fee schedules are comparable to that of other Suffolk County municipalities. Some fees are increasing, while others remain the same or have been reduced. You can find the new fee schedule on each Division’s webpage.

Any application filed with the Planning Division that obtains Planning Board and/or Town Board required approvals, and files with Building or Engineering Divisions prior to April 1, 2017, the 2016 fee schedule will apply. Applications and plans submitted that are not substantively complete, the application will not be grandfathered under the 2016 fee schedule.
