The technical name for this solution is known as the Integrated Solution (IS). In the City, the name has been further defined 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 the Columbus Land Redevelopment Office (Land Bank), abandoned, and vacant parcels for the implementation of Green Infrastructure (GI) with the long term goal to mitigate DSR activations, water-in-basement occurrences (WIBs) and street and yard flooding.
