Creating snow fence demonstrations with the UMN

Recent research as part of ongoing research between MnDOT and the University of Minnesota has highlighted the need for 1) demonstrations of blowing and drifting snow and blow ice snow fence control measures to show potential landowner-adopters of snow fences how they work and 2) how they affect agricultural operations and specifically how can interruptions in agricultural operations be minimized by snow fence designs... more »

Evaluate Effectiveness of Storm Ponds for Water Quality

Recent studies suggest storm water ponds may not offer the best long term treatment for water quality. Modeling of pond performance may not be accurate. Research is need to explore best management practices for stormwater treatment. State Aid Pre-screening meeting idea input: Are storm ponds still the best management practice for water quality application? Recent studies suggest storm ponds may not offer the best... more »

Vegetation management practices to enhance roadside pollinator habitat

Pollinators such as native bees, including the federally-endangered rusty-patch bumble bee (Bombus affinis), and Monarch butterflies are at risk due to the loss of native habitats from increasing development, intensive agricultural practices, and greater use of pesticides. Roadside habitats, in particular, have grown in importance as they can provide habitat and act as migratory corridors. The objective of this project... more »

Electronic NPDES Inspection and Performance Measurement Tools

The NPDES permit requires the owner and operator to inspect the entire site each week and after any rain fall greater than 0.5 inches in a 24 hour period. While the inspection report has a permit defined minimum criteria, the intent is a quality control and assurance tool for the owner/operator to correct deficiencies in a timely manner. This document creates something similar to a weekly punch list for scheduling the... more »

Stormwater Inlet Protection Device Determination of Performance

The NPDES permit requires inlet protection due to stormwater and construction operations. How to implement effective inlet protection remains a mystery if the intent is to 'protect' storm egress inlets while providing a flood prevention bypass and for all types of construction activities. Significant time and money are currently being expended in the purchase and installation of sediment and pollutant control inlets devices... more »

Assessing the Environmental and Aesthetic Impact of Litter in the Right of Way

As part of the development of MnDOT highway sponsorship program and the upcoming 30th anniversary in 2020 of the Adopt a Highway (AAH) Program, a research study is desired to determine the significance of various types of litter in MnDOT's right of way. The last formal analysis of the composition and frequency of litter in MnDOT's right of way was conducted in 1990. From an aesthetic and environmental standpoint, the... more »

Feasibility of Using Wetland Bank Program to Create Strategic Storage for Vulnerable Highway Infrastructure

Explore the feasibility of using MnDOT-BWSR joint wetland bank developments to create storage for highway assets vulnerable to flooding. If strategically located in the drainage area of vulnerable culverts or bridges, new wetland banks could reduce the risk of flooding without needing to replace or increase the size of existing infrastructure. This could help implement the SMTP strategy of "Support regional approaches... more »

Have Minnesota's Warmer Winters Increased the Number of Freeze Thaw Cycles?

It's been well documented that Minnesota's winters have gotten warmer over the last several decades. Our winters have warmed significantly faster than our summers. That trend is forecast to continue into the foreseeable future. It's possible that this warming has increased the length of time spent around 32F and increased the average number of freeze/thaw events. However, it's also possible that this warming has resulted... more »

Green Soil Decompaction using Tillage Radishes

Compacted soil causes poor turf establishment, low water infiltration rates, and increased short term erosion. Tillage Radishes are a cover crop that germinate and establish rapidly, have a long tap root, winter kill, and decompose rapidly. They return the soil nutrient to the soil and provide drainage paths through the soil as the root decomposes.
