Vermont Signficant Wetland Inventory Maps

USE OF THE VERMONT SIGNIFICANT WETLAND INVENTORY MAPS

***** UPDATE: Vermont updated its Wetland Protection and Water Resource Management Rules with the passage of bills H.447 (Act 031) in 2009 and H.763 (Act 110) in 2010. The passage of these bills establishes January 1, 2010 as the effective date for “proposed VSWI” wetlands to be regulated as Class 2 wetlands. To view materials related to this petition, click here. With the passage of the new Vermont Wetland Rules, effective September 15, 2010, regulatory jurisdiction will be asserted for wetlands that have significant function and value even if they do not appear on the VSWI map.

This Vermont Significant Wetland Inventory (VSWI) Map should not be relied upon to provide precise information regarding the location or configuration of significant wetlands. This map is intended only to denote the approximate location and configuration of significant wetlands. The actual boundaries of the wetlands depicted on this map must be determined in the field by Agency of Natural Resources (ANR) staff. Wetlands that have significant function and value that are not located on the maps may still be under the jurisdiction of the Rules. It is important to note that the Vermont Wetland Rules protect all Class I and Class II wetlands shown on this VSWI Map as well as all wetlands contiguous to such mapped wetlands. In other words, any wetland that touches or shares a boundary with a mapped wetland is also protected by the Rules, regardless of whether it appears on the VSWI maps. If a non-mapped wetland is adjacent to a mapped wetland, it is considered contiguous and is protected by the Rules. Also, if a wetland meets the presumptions listed in Section 4.6 of the Rules, it is presumed to be signficant and therefore protected. Wetland boundary determinations and determinations of whether a non-mapped wetland is contiguous or signficant are made by Vermont Wetlands Section upon request.

It is also important to note that the Vermont Wetland Rules apply to buffer zones contiguous to these wetlands (100 feet for Class One wetlands, 50 feet for Class Two wetlands, unless otherwise established by the Agency). Therefore, any activity in a Class I or Class II wetland, or their associated buffer zones, other than allowed uses specified in §6.2 of the Wetland Rules, requires a Wetland Permit from the Agency of Natural Resources (Vermont Wetland Rules, §6.2 and 9). According to §8.5 of the Vermont Wetland Rules, a permit can only be issued if it is determined that the use will have no undue adverse impact on protected functions, unless such impacts are mitigated. Mitigation measures include avoidance and minimization of wetland impacts. If there is any question as to whether a permit may be required for any particular project, it is always best to err on the side of caution by contacting the Vermont Wetlands Section to ask for a jurisdictional determination.

The Agency of Natural Resources Environmental Interest Locator is a map viewer that displays Agency of Natural Resources spatial data, which includes the Vermont Significant Wetland Inventory data layer. Use the USGS and NAIP Orthophotography layers in the imagery file to help you navigate to your site location, or find an address or environmental feature using the "Find Location" tool that loads with the map. Data layers are scale dependent and some layers will not become visible until you zoom in closer to your area of interest. This helps the map from becoming too cluttered with information. Switch to the layers view to toggle other Agency of Natural Resources data layers. Use the "Create PDF" tab to export a PDF document and for printing purposes. For further information on how to use the mapping application, click the Tutorial link on the disclaimer page.
