Navigating Suffolk County’s Complex Wetlands Maze: How Professional Property Surveys Unlock Development Potential While Protecting Natural Resources
Suffolk County property owners face an increasingly complex web of environmental regulations that can make or break development plans. With NYSDEC estimates that one million acres of previously unregulated freshwater wetlands may now be under NYSDEC’s jurisdiction following recent regulatory changes, understanding wetlands restrictions has become more critical than ever. Professional property surveys serve as the essential roadmap for navigating these environmental challenges while maximizing your property’s potential.
The New Reality of Wetlands Regulations in Suffolk County
The regulatory landscape for wetlands in Suffolk County has undergone dramatic changes. On December 31, 2024, NYSDEC announced the adoption of final revisions to its freshwater wetlands regulations, 6 NYCRR Part 664. The revised regulations took effect on January 1, 2025. These regulations implement amendments that the New York State Legislature enacted in 2022 to Article 24 of the Environmental Conservation Law (ECL)—the State’s Freshwater Wetlands Act (FWA)—which greatly expanded NYSDEC’s jurisdiction over freshwater wetlands in the state.
Under the new regulations, freshwater wetlands of any size if they are of “Unusual Importance,” which NYSDEC may designate based on any one of eleven expansive factors described below. Among other criteria, the “Unusual Importance” designation now gives NYSDEC jurisdiction over all freshwater wetlands in or adjacent to urban areas, and over some wetlands located within 2.48 miles of urban areas. This expansion means that many Suffolk County properties previously thought to be free from wetlands regulations may now require permits for development activities.
Why Property Surveys Are Essential for Wetlands Compliance
The most significant change affecting property owners is that as of January 1, 2025, the NYS Freshwater Wetlands Maps no longer define the extent of NYSDEC’s regulatory jurisdiction. Instead, property owners must now apply to NYSDEC for a jurisdictional determination to ascertain (a) whether their land contains either State-regulated freshwater wetlands or State-regulated adjacent areas (a “parcel jurisdictional determination”) and/or (b) whether a proposed activity on a parcel subject to NYSDEC freshwater wetlands regulation requires a permit (a “project jurisdictional determination”).
Professional property surveys become crucial because they help to determine the exact boundaries or location of wetlands in your property, provide a clear idea about what is present in your property, and help you take care of the legal and environmental requirements related to development within the area. Without accurate survey data, property owners risk costly delays, permit violations, or complete project shutdowns.
Local Suffolk County Requirements Add Another Layer
Suffolk County municipalities have their own wetlands regulations that often exceed state requirements. For example, permits shall delineate a specific buffer zone from the wetlands boundary for activities regulated by this chapter. The approving authority shall, where practicable, impose a minimum buffer zone of 100 feet for turf, fertilizers, pesticides, herbicides, fungicides or similar treatments, landscaping or other clearing or disturbance of natural vegetation, 125 feet for structures, and 150 feet for wastewater disposal and/or sanitary systems.
These local requirements make professional surveys even more critical, as they must accurately map not just wetlands boundaries but also the required buffer zones. The closest point from any wetland should be clearly marked depicting setbacks in liner feet. The existing and proposed edge of clearing shall also be shown on the survey.

The Survey Process for Wetlands Assessment
Professional wetlands surveys involve multiple steps to ensure compliance with all applicable regulations. For a simple wetlands delineation, a trained specialist will gather and document the wetland boundaries based on land-use maps, aerial photographs, topographic maps, soil surveys, and any other pertinent information. Additional information about the potential impact of the project may be needed for approval.
The survey must identify three critical diagnostic factors: prevalence of hydrophytic vegetation (plants that live in water or saturated soil conditions) under normal circumstances, meaning vegetation that would exist if not farmed; predominance of hydric soil (soils that are impacted by ground or surface water to support hydrophytic vegetation) and; wetland hydrology (ground or surface water that inundates or saturates soils sufficiently to support a prevalence of hydrophytic vegetation).
Avoiding Costly Mistakes
The consequences of proceeding without proper wetlands assessment can be severe. Where development is permitted, the regulations include additional requirements for minimum lot sizes; runoff restrictions; setback requirements for buildings, septic systems, roadways, accessory structures, etc. Projects requiring variances, or that propose development inconsistent with the Development Restrictions of Section 661.6 will probably require significant modification to avoid, minimize or mitigate impacts in order to be approved.
Professional surveys help you get an idea about what types of mitigation practices are required for the wetlands on your property and help to reduce or eliminate any damage caused by development to the local aquatic environment in your property.
Planning for Success
The key to successful development in Suffolk County’s regulated environment is early planning with professional guidance. Applicants proposing complex, multi-residential, commercial or industrial projects are strongly encouraged to schedule a pre-application conference. This meeting with DEC allows the applicant to clarify project objectives and obtain DEC’s recommendations. Such feedback can improve the project environmentally and shorten the application procedure.
