The Final Phase - Completing the Norwaldo Neighborhood Green Inftrastructure Project

In Indianapolis, Indiana a developed neighborhood was seeing localized flooding during smaller rain events. When the neighborhood was built in the 1960's, almost no storm water infrastructure was built as the neighborhood was established. HNTB Corporation was selected to help the Indianapolis Department of Public Works(DPW) solve the neighborhood's drainage issues. At the start of the project, the goal was to improve the neighborhood drainage, introduce green infrastructure where feasible and provide a lasting solution. This presentation will focus on how the project came together, starting with the planning phases of the project. The presentation will focus on the collaborative effort to develop multiple alternatives and work with stakeholder groups to develop a preliminary solutions. As the presentation continues, we will discuss how we transitioned from planning to design. As we shift to the design portion, we will continue to focus on the collaborative process developed to ensure that all stakeholders were happy with the final product. As we start the design portion of the project, we will talk about the community involvement, design issues encountered, and schedule that resulted in the final product. While working through the design, the DPW reinforced its desire to include green infrastructure where feasible. We will step through the design process of including permeable pavers, rain gardens and other aspects of green infrastructure into the project along with the calculations involved to ensure that Indianapolis Standards were met. We will also discuss the areas where green infrastructure was not feasible and talk about why those options were not feasible. In the last phase of the presentation, we will discuss issues that came up during construction of the project and how those issues were resolved during construction. We will focus again on how the team worked collaboratively to ensure a final product. We will talk about some of the challenges faced and highlight how the project was finished. We will walk through how the project team was able to accomplish the initial goals of the project and provide a long-lasting, sustainable solution to the neighborhood's flooding problems.
