Abstract
The Department of Public Works in Harford County has requested road segments at risk
of erosion be identified for preventive maintenance application. The final deliverable for this
project will be a map, data, and report categorizing the risk levels along with a list of the most
at- risk road segments. A Hot Spot Analysis identifying areas with the greatest concentration of
at-risk road segments will also be included.
The project had several phases. First, county road sections that were not bridges and
that were close to streams (<25 feet) were selected and isolated. Second, the team calculated
and characterized the soil type, drainage area, and distance from the stream as erosion risk
indicators. Third, the team created an index that weights soil type, drainage area, and distance
to identify the highest risk road segments. The team then separated the identified road
segments into high, medium, and low risk categories and produced a list of the 347 road
segments most at-risk. After a hot-spot analysis to find areas of the county that contain clusters
of high-risk road segments, the team finished by reporting to the county the roads in need of
checks or repair.
