Amherst Floodplain and Wetland Ordinances

Amherst, New York regulates development in floodplains and wetlands through local planning and building review to reduce property damage and protect waterways. This guide summarizes who enforces those rules, how to check whether a property lies in a regulated area, the permit and variance pathways, common violations, and practical steps to apply or report concerns. Where possible the guide cites official Amherst and New York State sources for current rules and contacts.^[1]

Scope and Key Rules

The Town of Amherst bases local floodplain management on mapped flood hazard areas and coordinates with state and federal programs. Wetlands protections are administered under state law with local review for development impacts that relate to town permits. For state-regulated freshwater wetlands and associated permits, see the New York State Department of Environmental Conservation guidance.^[2]

Permits, Maps, and How Regulations Apply

• Floodplain development permit - required where a proposed project intersects a mapped flood hazard area.
• Building permit - standard building permit review includes floodplain elevation and foundation requirements when applicable.
• Flood Insurance Rate Maps (FIRMs) - federal maps used to identify Special Flood Hazard Areas for local review.
• State wetland permit - projects affecting NYS-regulated freshwater wetlands require DEC review in addition to town permits.

Penalties & Enforcement

Enforcement is managed at the town level by planning, building, or code enforcement staff; state enforcement applies for regulated wetlands. Specific monetary fines and daily penalties for violations are not specified on the cited town pages; the town enforces compliance through stop-work orders, revocation or withholding of permits, and referral to enforcement proceedings when necessary.^[1]

• Monetary fines: not specified on the cited page.
• Escalation: first offence, repeat, or continuing offence ranges are not specified on the cited page; the town may issue stop-work orders and civil penalties.
• Non-monetary sanctions: stop-work orders, demolition or removal orders, permit denial or revocation, and court actions.
• Enforcer: Town of Amherst Planning/Building or Code Enforcement offices; state-level wetlands enforcement by NYS DEC.

• Defences/discretion: permits, variances, or documented mitigation plans may be considered; reasonable excuse language or specific defenses are not specified on the cited page.

Applications & Forms

The town publishes building and permitting application forms and instructions through the Planning and Building departments; specific form numbers and fee schedules vary by permit type and are posted on the official town pages. If a state freshwater wetland permit is required, submit applications to NYS DEC per their instructions.^[1]

Common Violations and Typical Outcomes

• Unpermitted filling or grading in mapped floodplain leading to stop-work and restoration orders.
• Construction without required floodproofing or elevation certificates, often triggering corrective permits and inspections.
• Disturbance of state-regulated wetlands without DEC authorization, which can result in state enforcement and restoration requirements.

Action Steps - Apply, Appeal, Report

• Confirm floodplain status: consult FEMA FIRMs and town floodplain maps as part of pre-application review.
• Submit required building and floodplain permit applications to the Town of Amherst Planning/Building office.
• Provide elevation certificates, engineering studies, or mitigation plans when requested by the review staff.
• Report suspected illegal fill, unpermitted work, or wetland disturbance to Town Code Enforcement or NYS DEC regional offices.
