Explanation
1. BACKGROUND: This project is being completed as part of the City’s Blueprint Columbus program. This project will design various types of green infrastructure (GI) for construction throughout the neighborhood which will provide a higher water quality within the region by treating the surface runoff before it discharges to the waterways. The project will also rehabilitate the existing sanitary sewer laterals and install or redirect new roof downspouts so as to reduce inflow and infiltration (I&I) within the sanitary sewer system which will result in fewer water in basements (WIBs), reduced sanitary sewer flows and decreased sanitary sewer overflows (SSOs). This contract renewal will provide the funding necessary to conduct additional public meetings and outreach, complete the designs of the GI and private property work as well as the assembly of the bid documents for each of the phases.
