There are many locations throughout the City of East Peoria where erosion and sedimentation create problems for surface transportation. The project goal is to collect accurate data on storm sewer outfalls to help access the degree to which the City's storm sewer infrastructure contributes to the erosion and siltation issue. The analysis will factor in other contributors, such as topography, filling operations, normal sheet drainage, or poor property management. There are areas in the city where storm sewer pipes become plugged with siltation, causing stormwater and silt to flow over the streets and flood the roadways. Some of these locations have speed limits of 40mph and surprise traffic with water and debris in the roadway. In some cases, it is known the siltation is coming from private property. In other cases, it is natural siltation, but the degree to which the city outfalls are contributing to the problem is unknown. The City's contribution to this issue will be assessed by expanding our inventory and knowledge of the storm sewer infrastructure. The ultimate goal is to develop a plan to mitigate the siltation and flooding along streets to improve roadway safety.
