Wetland Maps

Wetland Layers

The Wetlands Program edits the wetland advisory layer and the Vermont Significant Wetlands Inventory (VSWI).  The VSWI displays wetlands which are Class I or II and protected by the Vermont Wetland Rules.  Edits to the VSWI mapped polygons are noticed on the Environmental Notice Bulletin (ENB).  Wetland additions to the VSWI are added once a wetland determination of classification is made.  Wetland determinations are noticed for 30 days on the ENB and final decisions are posted there as well.  You may sign up for email notification of any VSWI edits or additions in your area through the ENB.  The wetland advisory layer is a informational layer of wetland locations which have not been formally assessed for significance.  Updates to the advisory layer occur quarterly on the Wetlands Inventory Map and ANR Atlas quarterly and are not noticed on the ENB.

The VSWI maps are intended to denote approximate wetland locations and boundaries. They should not be relied upon to provide precise information regarding the location or configuration of wetlands (see Section 3.2 of the Vermont Wetland Rules). Additionally, not all wetlands are mapped, and wetlands not mapped on the VSWI may still be considered significant. Only a qualified wetland scientist may determine the absence or presence of a wetland and its boundaries. 

The Secretary shall revise the VSWI maps to reflect wetland determinations issued by the Secretary pursuant to 10 V.S.A. § 914 and by the Panel pursuant to 10 V.S.A. § 915. The Secretary may also adjust the boundaries of wetlands shown on the VSWI maps to more accurately depict the location of a wetland, as determined by aerial photos, field visits, field delineations and other relevant information.

Wetlands Inventory Map

The Wetlands Inventory Map is a web-based mapping tool designed to help the public research wetland locations and features. Users may navigate to an area of interest, locate potential wetlands and other features, and create printer-friendly maps. The tool shows mapped wetland boundaries from the Vermont Significant Wetlands Inventory (VSWI), as well as wetland indicators including hydric soils, flood hazard zones, standing water, and vernal pools. Other features of special consideration when planning wetland-related projects are perennial surface waters (lakes & streams), rare, threatened and endangered (RTE) species and natural communities, impaired waters, and ground and surface water protection areas.
