Project Description: The Road Reconstruction project on South Geddes Street further exemplifies the continued partnership between Onondaga County and the City of Syracuse. This project is another example of the City’s Department of Public Works partnering with Onondaga County to include green infrastructure in their road reconstruction program. This application, within CSO 014, reduces pollution to Harbor Brook and Onondaga Lake.
The project uses three underground infiltration trenches between Delaware Street and Shonnard Street, to manage the runoff from South Geddes Street and parts of Merriman Avenue and Shonnard Street. By capturing this additional side-street runoff, the project is highly efficient, capturing nearly 2 million gallons annually. The infiltration trenches are designed to maximize the stormwater capture for the benefit of the environment. High flows from large rain events (above one inch over two hours) flow back into the existing combined sewer system for safety. The streetscape does not look different after the completed work, as the trenches are completely underground with no visible features at the surface. This project manages a total of 109,900 square feet of impervious drainage area, equating to approximately 1,981,500 gallons of stormwater runoff annually, in CSO 014. Construction was completed in summer of 2018.
