Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into an engineering agreement with Gresham Smith & Partners / OH Inc. for the Blueprint Linden, Hudson McGuffey Area project. The City has embarked upon its approved Wet-Weather Management Plan (WWMP). Currently, that plan is almost entirely comprised of a series of treatment plant capacity upgrades, storage tanks, tunnels, and other piping system augmentations; collectively known as “gray” infrastructure. After approval of the WWMP, the use of more renewable, sustainable, and environmentally friendly systems, commonly referred to as “green” infrastructure, has been recognized and implemented in many communities as a potential solution to many of the elements associated with consent order requirements.
Recently, the City received approval from Ohio EPA to delay many elements of the WWMP so the City can investigate whether it can meet the WWMP goals and future stormwater regulations with green infrastructure and I&I control on public and private property rather than with gray infrastructure. The technical name for this solution is known as the Integrated Solution (IS). In the City, the name has been further defined this as “Blueprint Columbus”.
The scope of work for this project is to perform all the requisite investigation, evaluation, formulation and design work to produce fully independent construction documents for the remediation of inflow and infiltration (I/I), green infrastructure (GI) technologies and other related activities and/or documents necessary for project completion of re-purposing of Columbus Land Redevelopment Office (Land Bank), abandoned, and vacant parcels for the implementation of Green Infrastructure (GI), with the long term goal to mitigate Saitary Sewer Overflows (SSO), water-in-basement occurrences (WIBs) and street and yard flooding.
The project will mitigate incidents of Sanitary Sewer Overflows to the 10-year level of servic...
