Impact Assessment of I-80 Redevelopment on City's LTCP
Boomi assisted the City of Paterson and Passaic Valley Sewerage Commission (PVSC) in developing a series of alternative analyses to support the regional long-term sewer control plan for the City of Paterson. This included planning and design of green and grey stormwater infrastructure improvements to help manage CSO issues within the city.
Project Owner
Passaic Valley Sewerage Commission (PVSC), New Jersey Department of Environmental Protection (NJ DEP), and City of Paterson, NJ
Project Location
Paterson, NJ
Project Context
The city of Paterson, NJ has a combined sewer system that causes an annual CSO volume of over 350 million gallons. The City of Paterson and Passaic Valley Sewerage Commission (PVSC) developed a regional Long Term Control Plan (LTCP) which includes a goal of a 20% CSO volume reduction.
Project Challenge
The LTCP includes 75 acres of green infrastructure that is expected to manage 2.5% of runoff from impervious surfaces. A potential expansion along interstate I-80 may also have impacts on drainage and flooding within the city.
Our Solution
Our team developed an existing conditions model in InfoWorks ICM to establish the CSO volume within each city sewershed. The team identified the CSO outfalls and sewersheds that contributed the highest overflow volumes and potential sites for GSI implementation. We also expanded the model to include high-resolution areas along interstate I-80 to evaluate impacts on drainage and flooding from the proposed highway expansion and made recommendations.
