<DIV STYLE="text-align:Left;font-size:12pt"><DIV><DIV><P STYLE="margin:0 0 0 0;"><SPAN>The Wetland Advisory Layer is a supplemental wetland mapping layer. It does not carry the same regulatory weight as the Vermont Significant Wetland Inventory (VSWI) maps, but may provide better information on the size and configuration of wetlands in the landscape. There are multiple sources for the advisory layer, but this layer is not uniform across the state due to its origins.</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN STYLE="font-weight:bold;">Regulatory Meaning:</SPAN><SPAN> Where the advisory layer touches or overlaps with a VSWI layer, it is likely protected by the Vermont Wetland Rules (VWR). If the wetland meets the presumption of significance listed in Section 4.6 of the Vermont Wetland Rules, it would also be considered a Class II wetland. Any work in a Class I or II wetland or its jurisdictional buffer, including filling, dredging, draining, ditching, cutting woody vegetation, may require a permit from the Vermont Wetlands Program. Both Class I and Class II wetlands appear on the VSWI maps. Class II wetlands have a 50-foot buffer which is protected, and Class I wetlands have a 100-foot regulatory buffer. These buffers are measured from the edge of a delineated boundary (field verified) from the wetland.</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN /><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN STYLE="font-weight:bold;">Origin: </SPAN><SPAN>Wetland Advisory maps are a combination of wetland mapping created by towns, from Wetland Program site visits, or by advanced state mapping efforts. Where base maps originate from aerial photography, those imagery is more recent than National Wetland Inventory derived VSWI maps. Some advisory layers use LiDAR and have also had field verification, such as the pilot project that mapped the Missisquoi River Basin in 2019.</SPAN></P></DIV></DIV></DIV> |
