Transfer of Density Flow Rights
Town of Smithtown Transfer of Density Flow Rights Program
Background:
Long Island sits atop three aquifers that are the sole sources of drinking water for the island. To protect our drinking water from contamination, Suffolk County regulates the amount of wastewater (water from your bathroom, kitchen, laundry room, etc.) that can be discharged on properties. In this area of the County, owners have the right to generate 300 gallons of wastewater per day (gpd) per ½-acre. However, some owners would like to use their properties more intensively, and others, less intensively. In such cases, the County allows owners to transfer rights from one property to another. In 2010 the Town adopted a code to administer this program for the County. The objectives of the program are:
A. Preservation of open space and environmentally sensitive land,
B. Protection of groundwater from contamination, and
C. Preservation and enhancement of the Town's three historic central business districts.
For more information on the program, please review the answers to our Frequently Asked Questions. If you do not find the answer to your question in the FAQs, please call the Planning Department at (631) 360-7540. You can also refer to the Transfer of Density Flow Rights ordinance (§323 of the Town Code).
