Environmental Protection New York 4 Minutes Read ยท published March 08, 2026 Flag of New York

Overview

This guide summarizes local permit requirements for sewer connections, stormwater controls, construction dewatering and related site work in Greenburgh, New York. The Town of Greenburgh Building Department and Department of Public Works administer local permits and inspections; state stormwater permits (SPDES) and enforcement are handled by the New York State Department of Environmental Conservation when applicable. For local permitting procedures consult the Town of Greenburgh official pages Town of Greenburgh Building Department[1] and for state SPDES requirements consult the NYSDEC guidance NYSDEC - Stormwater Program[2].

Contact the Building Department early to confirm whether a sewer or stormwater permit is required.

When a Permit Is Required

Typical triggers for a sewer or stormwater permit in Greenburgh include connection or alteration of a sanitary sewer lateral, construction that disturbs land requiring stormwater management, new impervious surface over the local threshold, significant grading, or discharges to municipal storm sewers. Larger projects may also require NYSDEC SPDES coverage or county-level approvals.

Application Process

Applications usually require engineering plans, erosion and sediment control details, a drainage analysis, and contractor insurance information. Submit plans to the Building Department and, when applicable, to the Department of Public Works for municipal right-of-way work.

Applications & Forms

  • Permit application form for sewer connections: see the Town of Greenburgh Building Department for the current form and submittal instructions; specific form name/number not specified on the cited page.[1]
  • Stormwater control plan requirements: NYSDEC posts SPDES permit guidance and construction stormwater general permits on its site; specific local checklist not specified on the cited page.[2]

Plan Review, Inspections & Approvals

After submission the Building Department reviews plans for compliance with the Town Code and local standards. The Department of Public Works inspects any work in town streets or on municipal infrastructure. If a SPDES permit is required for stormwater discharges, NYSDEC must be notified per state rules and may conduct inspections.

Keep erosion control measures active until vegetation is established to avoid stop-work orders.

Penalties & Enforcement

Enforcement for sewer and stormwater violations may involve local fines, work stoppage orders, remediation orders, and referral to state enforcement where SPDES violations occur. Detailed penalty figures and escalation steps are not listed on the Town of Greenburgh pages and therefore are not specified on the cited page; NYSDEC enforcement policies apply to SPDES violations and are available on the DEC site but specific monetary ranges are not reproduced here from that page.[1][2]

  • Fine amounts: not specified on the cited Town and DEC pages.[1]
  • Escalation: first, repeat and continuing offences may trigger higher administrative fines or court action; specific escalation ranges are not specified on the cited pages.[2]
  • Non-monetary sanctions: stop-work orders, remediation orders, suspension of permits, equipment seizure or referral to courts for injunctive relief.
  • Enforcers and complaint pathway: Town of Greenburgh Building Department and Department of Public Works handle local complaints; county and NYSDEC handle stormwater/SPDES enforcement. For county stormwater program contact Westchester County Environmental Planning and Stormwater units for municipal coordination.Westchester County Stormwater & Environmental Programs[3]
  • Appeals and review: appeals typically follow local administrative appeal procedures through the Town; specific time limits for appeals are not specified on the cited Town pages.
If you receive a violation notice, note any appeal deadline listed on the notice and act promptly.

Applications & Forms

  • Where to file: submit sewer-connection and stormwater permit applications to the Town of Greenburgh Building Department; details and submission address are on the Town site but specific fee schedules or form numbers are not specified on the cited page.[1]
  • Fees and deposits: fee schedules vary by application type and project scope; specific fees are not specified on the cited Town page.

Common Violations

  • Unauthorized sewer connection or work in the public right-of-way.
  • Failure to implement or maintain erosion and sediment controls during construction.
  • Discharging construction dewatering or contaminated runoff to storm drains without permits.

How-To

  1. Confirm whether your project triggers a sewer or stormwater permit by contacting the Town of Greenburgh Building Department and reviewing NYSDEC SPDES guidance.
  2. Hire a licensed engineer to prepare plans including stormwater management and erosion control details.
  3. Complete and submit permit applications, required plans, insurance certificates and any fee to the Building Department; obtain any DPW approvals for work in streets.
  4. Secure NYSDEC SPDES coverage if the project meets state thresholds and file required notices or SWPPP where applicable.
  5. Schedule inspections with the Town and maintain erosion controls until final stabilization; comply promptly with any remediation orders.
  6. If you receive enforcement, review the notice for appeal instructions and timelines and consider applying for a variance or permit modification if justified.
