Building near the water in Worcester, Massachusetts (wetlands rules)
Building, grading or clearing within 100 feet of any wetland, bank, lake, pond or stream in Worcester needs a permit from the Conservation Commission under the city's Wetlands Protection Ordinance. The city's regulations generally bar any new structure within 30 feet of a resource area and any grading or clearing within 15 feet, unless the Commission grants a specific allowance or waiver.
| Local jurisdiction (buffer zone) | Within 100 ft of wetlands, banks, lakes, ponds, rivers and streams, plus land under water and land subject to flooding [1] |
| No-structure setback | 30 ft from any resource area [4] |
| No-disturbance setback | 15 ft from any resource area (grading, filling, clearing) [5] |
| Approving body | Conservation Commission (permit after public hearing) [2] |
| Local NOI fee, single-family lot work | $75 (addition, pool, deck) [7] |
| Floodplain overlay | Floodplain development permit required for any development [8] |
Where the rules apply
The 30-foot and 15-foot setbacks and the fees come from the Conservation Commission's Wetlands Protection Regulations as last amended June 24, 2019, the version the city posts; they may have changed since. Worcester's Wetlands Protection Ordinance bars anyone from removing, dredging, building on or altering land within 100 feet of any freshwater wetland, marsh, wet meadow, bog, swamp or bank. The same goes for any lake, river, pond or stream, the land under them, and any land subject to flooding, unless the Conservation Commission permits it [1]. The regulations call this 100-foot band the buffer zone [3]. The ordinance also covers land within 100 feet of storm drain inlets that drain to water bodies, though most small projects there are exempt. That includes projects disturbing under 10,000 sq ft on slopes under 15%, and any project served by the combined sewer system.
Setbacks and clearing
In the buffer zone, the Commission presumes that removing vegetation (other than routine lawn and garden care), grading, filling, excavating and putting up permanent structures may harm the resource area [6]. The regulations generally ban any permanent or temporary structure within 30 feet of a resource area [4], and any grading, filling, excavation or vegetation removal within 15 feet [5]. The Commission can allow work closer than that if you show there's no reasonable alternative, the design keeps work away from the resource, and the site can be protected. Under the ordinance, "alter" includes building or adding to structures and clearing more than 10,000 sq ft of vegetation.
Getting approval
File an application (a Notice of Intent) with the Commission before any regulated work. Nothing may start until you have a permit and follow its conditions [2]. If you're unsure whether your project is covered, request a determination in writing. The Commission holds a public hearing, generally combined with its hearing under the state Wetlands Protection Act. It must start the hearing within 45 days of a complete filing and decide within 35 days after it closes. Local fees for a single-family lot are modest [7], and filing after work starts doubles the fee.
Floodplains
In the zoning Floodplain Overlay District, any development, including additions, fences and sheds, needs a floodplain development permit from the Director of Code Enforcement [8]. A building permit or Conservation Commission permit may substitute where applicable.
The ordinance doesn't separately address expanding nonconforming structures near water; ask the Commission.
Next steps
- Check whether your property is within 100 feet of a wetland, pond, lake, stream or bank, or in the floodplain overlay, using the City's maps, or ask the Conservation Commission staff in Planning & Regulatory Services (planning@worcesterma.gov, 508-799-1400).
- If unsure, file a Request for Determination of Applicability ($50 for the first acre plus a $25 advertising fee).
- For work in the buffer zone, hire an engineer or wetland scientist to prepare plans and file a Notice of Intent with the Conservation Commission; attend the public hearing.
- Get the Commission's permit (Order of Conditions) before applying for a building permit, and request a Certificate of Compliance when the work is done.

Massachusetts wetlands rules and the Conservation Commission
Massachusetts has no "shoreland zoning" like some states. Instead, the Wetlands Protection Act (M.G.L. c. 131, §40) and MassDEP's regulations (310 CMR 10.00) control work near water, and your local Conservation Commission enforces them.
What's protected:
- Wetlands, banks, beaches, dunes, marshes, land under ponds and streams, and 100-year floodplains.
- The riverfront area: 200 feet from a perennial river or stream, shrinking to 25 feet in certain dense urban areas.
- The buffer zone: land within 100 feet of a wetland, bank, beach or similar resource area. Most work here needs Conservation Commission review.
How approval works:
- Contact the Conservation Commission before starting any work in these areas. That includes additions, decks, sheds, driveways, regrading and clearing vegetation.
- If you're unsure whether the law applies, file a Request for Determination of Applicability (RDA).
- If the work will affect a resource area, file a Notice of Intent (NOI) with plans and a fee. A public hearing follows, and the commission issues an Order of Conditions approving (with conditions) or denying the project.
- Applicants, abutters, groups of 10 residents or MassDEP can appeal to MassDEP.
Local bylaws can be stricter. Many towns have their own wetlands bylaw with larger buffers or no-build zones, and the Conservation Commission enforces those too.
