Project Summary

To explore how green infrastructure installations can function as part of climate resilient pedestrian transportation systems, the Minnesota Department of Transportation tasked Toole Design with developing a two-pronged plan.

From a policy perspective, we are analyzing and suggesting changes to MnDOT’s guiding documents, programs, and policies so they are aligned with the agency’s sustainability and climate resilience goals. This task will help move MnDOT toward better climate mitigation and adaptation practices for pedestrians while also providing consistent guidance across the agency.

On the other end of the spectrum, we are leading engagement-based tasks to gain buy-in from MnDOT District staff as well as the public. These include two tactical green infrastructure demonstration projects to illustrate the value and versatility of green infrastructure throughout the state. These pilot projects set a standard for future climate resilience projects by combatting impacts of heavy precipitation and flash floods, reducing air and water pollution, lowering heat island effects, and expanding pollinator habitats.

The plan uses clean and colorful graphic examples of climate-resilient infrastructure, including this diagram of a stormwater curb extension.
Another green infrastructure element recommended to MnDOT is a bioretention pond where native plants help treat runoff water before entering the basin.
Stormwater curb cut inlets control runoff during all seasons without extending into the pedestrian access.
