Nassau County 239-f Reviews
Pursuant to New York State General Municipal Law § 239-f, certain building permit, subdivision, and site plan applications must be referred to the Nassau County Department of Public Works (NCDPW) for review before the Village of Bayville can issue an approval. This county-level review ensures that local development does not negatively impact county-owned roads, drainage systems, or infrastructure, while maintaining traffic and pedestrian safety.
If your project requires a 239-f review, you must complete the appropriate NCDPW 239-f Referral Application (Residential or Commercial) along with a 239-f Initial Submission Checklist. The checklist and civil site plan package must be signed and sealed by a New York State licensed professional engineer or architect.

Nassau County Fire Prevention Ordinance
The Nassau County Fire Prevention Ordinance establishes uniform safety regulations designed to protect life and property from fire and explosion hazards across the county. Working alongside New York State building codes, this ordinance dictates the specific requirements for installing, testing, and maintaining essential life-safety equipment, including fire alarms, automatic sprinkler systems, and commercial kitchen hood suppression units. It also strictly regulates the safe storage and handling of flammable liquids, hazardous materials, and combustible substances. Enforced by the Nassau County Fire Marshal’s Office, these regulations ensure that commercial businesses, public assemblies, and multi-tenant structures maintain clear evacuation routes and fully functional fire protection systems to safeguard the community.
NYSDEC & USACE Joint Application for Tidal Wetlands
In the Village of Bayville, many coastal and waterfront properties fall under the jurisdiction of state and federal environmental agencies. If your proposed project involves construction, excavation, dredging, or the placement of fill within a tidal wetland or its regulated adjacent area (up to 300 feet inland from the wetland boundary), you are required to submit a Joint Application for Permit.
This unified application streamlines the environmental review process by allowing you to apply for necessary permits from multiple agencies at once, including:
- New York State Department of Environmental Conservation (NYSDEC)
- U.S. Army Corps of Engineers (USACE)
- New York State Department of State (DOS) (for Coastal Consistency)
- New York State Office of General Services (OGS)
Common Regulated Activities: A Joint Application is typically required for bulkheads, seawalls, docks, piers, floats, and beach nourishment. It is also required for upland residential construction within the 300-foot adjacent area, including new home construction, swimming pools, decks, garages, and septic systems.
Important Note: Obtaining a NYSDEC or USACE permit does not exempt you from local zoning and building codes. Village of Bayville building permits must still be secured prior to the start of any construction.

Nassau County Dept. of Health On-Site Sewage Disposal (1983 Manual)
Because the Village of Bayville is an unsewered community, properties rely on private on-site sewage disposal systems (septic tanks and cesspools) and stormwater retention systems (drywells). The design, sizing, installation, and modification of these systems are strictly regulated by the Nassau County Department of Health (NCDOH) in accordance with their 1983 On-Site Sewage Disposal Manual.
All proposed wastewater systems must comply with the 1983 Manual’s standards for daily flow calculations, soil percolation rates, groundwater separation, and strict setback distances from property lines, foundations, and tidal wetlands. Site plans and system designs must be prepared, signed, and sealed by a New York State licensed professional engineer or architect.
