CCRPC MRGP

Municipal Roads General Permit Quantifying roadway erosion issues through data driven analysis Stormwater runoff increases erosion, which can negatively impact water quality in Vermont. Through the results of the Clean Water Act, a new permit issued by VT ANR called the Municipal Roads General Permit (MRGP) will be required for all towns in Vermont. This permit sets roadway erosion standards, and by bringing all municipal roads up to these standards, we can achieve significant reductions in stormwater-related erosion from municipal roads, both paved and unpaved. The Data Road Erosion Inventory click me! Evaluation of Results Upon completion of the Road Erosion Inventory (REI), the CCRPC evaluated, or 'scored' all segments. This process looks at all of the discrete variables observed during the field inspection to determine whether a given road segment Fully Meets, Partially Meets, or Does Not Meet MRGP road erosion standards. The initial results are below. A Deeper Dive Rather than providing simplified maps and access to the data itself, CCPRC staff have created an interactive dashboard to explore the data on a more detailed level.  On the right is a dashboard for all of Chittenden County.  Below are dashboards built for individual municipalities. Planning and Implementation Although the Municipal Roads General Permit is a 20 year permit, there are intermediate goals towns will need to meet. In roughly five year intervals, municipalities will need to bring a certain percentage of their segments up to standard. Through the inventory, scoring, and analysis of Chittenden County's REI data, the CCRPC have helped towns in their planning efforts to prioritize project locations that have a greater impact on water quality. Consultants on retainer are providing scoping level solutions for these identified areas and are positioning towns for competitive grant programs with quality reports. The CCRPC is trying to help Chittenden County municipalities get ahead of the game through assistance with various state and federal funding mechanisms. This occurs not only in the planning/scoping of projects as shown on the right, but in acquiring grants for physical construction. Better Data, Better Decisions An example of South Burlington's Stormwater infrastructure (green) and connected segments (red/pink) Across Chittenden County, 3,375 curbed segments "drain" to 758 hydrologically connected outfalls. Only 501 of these outfalls have been inventoried as there are questions as to whether they serve municipal storm systems (instead of private or state roads). This information needs a more robust GIS analysis which will rely on the comprehensiveness and accuracy of a given municipalities' stormwater data. Work in Progress CCRPC will continue to use this platform to inform public officials for better decision making. In the future we hope to expand on exploring this data at a more town specific level. please check back for future updates!
