Informational Meetings for Proposed Updates to Wisconsin's Wetland Indicator Layer

The first step land owners, developers and builders need to take before picking up a shovel or calling in the bulldozers is determining whether a proposed project site is located within a wetland. A new upgrade to the Department of Natural Resource’s interactive wetland indicator map found at dnr.wi.gov will make it easier to determine if a project has the potential to impact wetlands.

“The advantage of this new upgrade is to target potential wetlands on a land owner’s property to avoid any inadvertent wetlands disturbance during development and avoid unnecessary wetland delineation costs,” says Amanda Minks, DNR Waterway and Wetland Policy Coordinator.

Minks said the DNR has been working with the National Resource Conservation Service to integrate updated soil information, field reporting and digital topography tools to its current map, which is referred to as the pink layer, so that the agency can provide users with the most comprehensive tool possible.

If wetland impacts are possible, state law requires a wetland delineation to confirm wetland impacts and determine the amount of the potential impact. The newly upgraded tool will allow users to target areas at a more refined scale, which can help avoid or minimize wetland impacts and determine the appropriate regulatory process for projects.

To preview the updated system to potential users, the department is hosting two hour-long informational meetings on Tuesday, March 6, 2018, 10:00 a.m., at the Green Bay Service Center, and Friday, March 9, 2018, 2 p.m., in room G09 at the DNR Central Office, 101 S. Webster, in Madison.

“We want to give our potential users an opportunity to experience the changes before we release the final upgrade to the public in late spring this year so they will better understand the changes and how to use the layer,” Minks said.
