Black Earth Creek Watershed

Green Infrastructure Plan

Communities, businesses, and farms surrounding Black Earth Creek were hit hard by flooding in August 2018. Black Earth Creek is a high-quality cold-water trout stream just west of Madison, Wisconsin that flows through three villages, across farmland, and attracts recreationists for fishing, kayaking, and other activities.

Silvernail Geodesign is part of a team working with local partners and communities to identify where we can best locate green infrastructure practices, or landscape features to catch rainwater where it falls, to be most effective at improving flood resiliency and enhancing water quality.

What We Are Doing

We are designing scenarios using modeled flood risk maps in Esri Geoplanner to locate urban and rural green infrastructure features at key places around the watershed. We can interactively evaluate the scenarios against key performance metrics shown dynamically in dashboards within Geoplanner.

To foster collaboration and community engagement in the project, our team has built an ArcGIS Hub Initiative. Hub allows us to share maps, events, and other content, and invite community followers to provide feedback in the process. We will be adding the green infrastructure scenarios and their metrics, creating a living plan that grows as the project progresses and stakeholders participate.
