Projects:
March Run Gabion Replacement Project
The Marsh Run Gabion Replacement Project was identified as one of fifteen projects in our Stormwater Action Plan developed in 2020. This project included the removal and replacement of the existing gabion basket streambank stabilization for an estimated length of 180 linear feet. The wire structure of the lower baskets has scoured, failed and no longer adequately supports the upper baskets.
Indiana Borough applied for LSA funding in 2022 and was awarded the funds in 2023. The project included the removal and replacement of an existing gabion basket streambank stabilization along portions of Marsh Run downstream of Washington Street to restore its stability and functionality The replacement stabilized the streambanks, enhancing the flow capacity of the channel, and significantly reducing the potential for erosion in the project area. This improvement will help to reduce future stream restoration and sedimentation removal costs, will preserve property values for the affected parcels, and will help reduce residential flooding.
On-going Projects:
Marsh Run Streambank Stabilization Project
The Marsh Run Streambank Stabilization Project was identified as three more of the fifteen projects in our Stormwater Action Plan developed in 2020. As they are all located along the same waterway, we were able to apply for funding for multiple project sites. We applied to the Growing Greener Grant Program in 2023 and were awarded funding in 2024. This three-part project will address the following sites:
Project 1: Streambank Stabilization -- Coulter to Poplar Avenue: Targets Marsh Run at Coulter and Poplar Avenues and focuses on stream realignment and stabilization of the west stream bank for a length of 160 feet. The stream will be realigned to correct the severe erosion and bank cut occurring along the west bank. The proposed method of stabilization is installation of an Envirolok Wall system along the west stream bank. This will alleviate urban runoff by mitigating erosion and sedimentation, thus directly addressing one of the impairment sources. Stream realignment will improve the flow and help to control water temperature, offering a solution for the identified impairment cause of thermal modifications.
Project 2: Streambank Stabilization – Willow Avenue to 7th Street: Stabilizes the eroded and undercut streambank along Marsh Run from Willow Avenue to 7th Street for a total length of approximately 230 feet. By planting an estimated 500 live stakes complemented with a protective blanket, we further combat erosion and sedimentation. Live stakes aid in natural streambank reinforcement and provides shade that assists in maintaining a balanced water temperature.
Project 3: 5th Street Bridge Approach Channel Stabilization -- Targets the sediment deposit and bank erosion along Marsh Run just upstream of the 5th Street Bridge. The sediment deposit, which restricts flow and exacerbates flooding in nearby residential areas, will be removed from the stream and the west streambank will be stabilized using an Envirolok Wall system for a length of 110 feet. Our approach will improve the stream alignment for more efficient flow into the bridge and stabilize the streambanks against erosion. This will enhance water flow efficiency, reduce flood risk, and manage urban runoff impacts.
In all, these three projects holistically address the identified impairment sources and causes, contributing to the restoration and long-term health of Marsh Run. Not only do they aim to improve water quality and the local ecosystem, but they also strive to protect our community from flood risks associated with urban runoff.
