Southampton Village, NY Environmental Rules: Stormwater Management (2026)

Chapter 93 of the Southampton Village Code, adopted 10-26-2010 by L.L. No. 6-2010, applies to all land development activities. Section 93-3B designates the Village Building Inspector as the Stormwater Management Officer, and § 93-3C requires every land development activity to submit a SWPPP to that officer for review and approval. Section 93-5A goes further: no application for approval of a land development activity gets final approval, and no land development activity can be undertaken, until the officer has received, reviewed and approved the SWPPP. The officer can engage a registered professional engineer appointed or authorized by the Board of Trustees, or accept the certification of a qualified professional. Projects that also need Planning Board subdivision or site plan approval are reviewed under the same standards, and the officer forwards the approved SWPPP to the Planning Board under § 93-3D.

Section 93-4 exempts agricultural activity, silvicultural activity (landing areas and log haul roads stay covered), routine maintenance that disturbs less than five acres, cemetery graves, installation of fence, sign, telephone and electric poles and other posts, emergency activity to protect life, property or natural resources, home gardening, and landscaping and horticultural activities in connection with an existing structure.

Larger or more sensitive sites add postconstruction runoff controls under § 93-5B(2). Condition A covers runoff to a 303(d) impaired water or TMDL watershed, Condition B covers disturbance of five or more acres, and Condition C covers disturbance between one acre and five acres, exclusive of single-family residences and agricultural properties. Section 93-6 makes the New York State Stormwater Management Design Manual an official guide and bars any increase in turbidity that results in substantial visible contrast to natural conditions in surface waters. After construction, § 93-7D requires a maintenance agreement recorded in the office of the County Clerk as a deed restriction before final plan approval.

For single-family land development that disturbs less than five acres and does not meet Condition A, the initial SWPPP review fee under § 93-11C(1) is $2,000. Other reviews recover the reasonable professional costs incurred by the Village, and the officer can require a $2,000 deposit.
