Clearing Near Wetlands, Streams, and Shorelands

A map line is not a work boundary, and every agency involved says so in its own words. In Vermont, most mapped wetlands are Class II and carry a 50-foot buffer, and removing vegetation inside the wetland or that buffer needs a Vermont Wetland Permit unless it is an Allowed Use under Section 6 of the rules. In New York, DEC regulates freshwater wetlands over 12.4 acres plus a 100-foot adjacent area, with the threshold dropping to 7.4 acres on 1 January 2028, and DEC states plainly that its maps are not a final determination.

It sets out wetland trigger and buffer or adjacent area and authority across 5 rows, covering vermont, vermont shoreland, new york and more. It is on this page so the comparison can be read directly rather than reconstructed from prose.

Screen the parcel on the state mapping tool — as a question list, not an answer. That comes first because everything after it depends on the answer, and reversing the order is what makes this scope expensive.

1. Screen the parcel on the state mapping tool — as a question list, not an answer. 2. Request the jurisdictional review or field delineation the project needs. 3. Mark the determined boundary on the ground and photograph the marks. 4. Establish stable upland access and staging outside the line. 5. Keep mulch, soil, fuelling and machine tracks upland of it. 6. Stabilise anything disturbed before the next rain.

Stabilise anything disturbed before the next rain. It gets skipped because by that point the visible problem is solved, and the cost of skipping it does not appear until the following season.

Using a mapped boundary as the work limit. Close behind it: Assuming a dry summer means not a wetland. Fuelling or servicing a machine near the line. Assuming a Vermont answer applies in New York or New Hampshire.

Because a planning guide to mapping, buffers, permits, erosion, and qualified review — and none of those variables can be answered by a number. A range is arithmetic on assumptions; this page is the list of assumptions worth checking first.

No. Nothing here is a permit determination, a wetland delineation, a boundary opinion or a safety finding — including "screen the parcel on the state mapping tool — as a question list, not an answer", which is guidance about what to establish, not a statement that it has been established. The property owner is the applicant for every approval on clearing near wetlands, streams, and shorelands, and the authorities behind the 4 rules cited on this page are the ones whose answers count.

The 4 rules cited on this page each carry the authority it came from and the date it was checked against that authority's own published material. The "Wetland and shoreland jurisdiction, by state" table is dated the same way. Rules change — the check date is printed so you can see how old the answer is rather than having to guess, and on clearing near wetlands, streams, and shorelands the figures most likely to move are the ones with a scheduled change already announced.

A 50-foot buffer zone runs contiguous to the boundary of every Class II wetland, and most mapped wetlands in Vermont are Class II. Removing vegetation, filling, dredging, ditching, draining or grading inside the wetland or that buffer needs a Vermont Wetland Permit unless it is an Allowed Use under Section 6 of the rules. Clearing vegetation is explicitly named in the regulated activities, so a mulching pass into a buffer is a permit question even though nothing is being built. On clearing near wetlands, streams, and shorelands specifically this bears on step 2 of the sequence on this page — request the jurisdictional review or field delineation the project needs — because that is where the boundary between what you may do and what you may not gets fixed.

A Freshwater Wetlands Permit is required to drain, dredge, excavate, fill, pollute or erect structures in a regulated wetland or within the 100-foot adjacent area around it. DEC currently regulates freshwater wetlands over 12.4 acres (5 hectares). The size threshold drops to 7.4 acres on 1 January 2028, which will bring wetlands that are outside jurisdiction today inside it. DEC also states that its maps are a screening tool, not a final determination — a mapped absence is not permission.

Inside the jurisdictional areas described in RSA 482-A and the Env-Wt administrative rules, a wetlands permit may be required to excavate, fill, dredge, remove material or construct structures. New Hampshire approvals are separate from Vermont ones. A contractor working across the river holds no standing in either state's process; the landowner is the applicant.

The Shoreland Water Quality Protection Act establishes protected shoreland within 250 feet of the reference line of public waters, measured horizontally. All fourth-order and greater streams and rivers are covered as well as lakes and ponds. Vegetation removal, excavation, fill and development inside that band are regulated. Wetlands and shoreland are two separate permits that can overlap. Impacts already covered by a wetlands permit do not need a separate shoreland permit for those same impacts, but any impact inside the protected shoreland that the wetlands permit does not cover still does.
