demonstrated to be similar in both cost and performance. Because the Overflow Control Program represents the largest infrastructure investment in Kansas City's history, city officials are committed to using this investment to encourage future neighborhood investments. In an effort to leverage this investment for the betterment of local neighborhoods, Kansas City has allocated more than $68 million for the installation of green infrastructure projects. This investment is already proving to be successful, both in the reduction of combined sewer overflows and in strengthening the local community. In 2012, the completion of Kansas City's nationally recognized green infrastructure pilot project showcased the community and environmental benefits of incorporating green infrastructure solutions for the on-site control of rainwater. The purpose of the pilot project was to test a wide range of infrastructure and streetscape improvements to reduce combined sewer overflows within a 100-acre area pilot project area. Before receiving EPA approval to replace gray infrastructure with green solutions, Kansas City had planned for the installation of two large storage tanks. Measured in cost-per-gallon, this gray infrastructure solution had represented one of the more costly improvements in the early years of the program. In 2013, Kansas City filed a report with the EPA confirming that the green solutions in the completed 100-acre pilot project area are successfully performing on-par with more traditional gray infrastructure solutions — but with the added benefit of revitalizing a community. The completed pilot project area achieved a total constructed storage volume of 360,320 gallons thanks in part to the installation of more than 130 best management practices (BMPs) such as rain gardens, permeable pavers, and porous sidewalks. Construction for the remaining 644 acres of green infrastructure improvements will be conducted this year. "The green infrastructure solutions included as part of Kansas City's Overflow Control Program are transforming neighborhoods and serving as a catalyst for city and community partnerships," said Shively. "Kansas City's plan to replace gray infrastructure with green solutions was born from data and strategic planning, and it is made possible through strong partnerships with the local community." Contagious Commitment This investment and the proven success of the city's green infrastructure pilot project have instigated a citywide commitment to sustainability. In 2014, Kansas City's mayor pro tempore became one of the first elected officials in the nation to achieve accreditation as an Envision Sustainability Professional, and the program has served as a guide for sustainable practices throughout all city departments. Kansas City Water Services is leading the city's sustainable initiative by incorporating the Envision principles into project planning for the Overflow Control Program and into the long-term plan for the utility. Additionally, collaboration among various city departments has enabled the strategic allocation of city resources that will further enhance the community investment in green infrastructure solutions. Stakeholders representing the city's Parks and Recreation, Public Works, Neighborhoods and Housing Services, and Planning and Development departments convene on a monthly basis to discuss ways that resources and services in the green infrastructure project area can be improved. This collaboration has already resulted in streetscape improvements, enhanced trash services, and the reallocation of vacant properties. In addition to pooling municipal resources to enhance the city's existing green infrastructure investment, this group has worked to assist community leaders to request public funding for enhancements to neighborhood curbs and sidewalks which will provide safe connections for pedestrians and bicyclists in the community. 14 wateronline.com ■ Water Innovations Kansas City's pilot project has proven that green solutions, such as street curb extensions, are equally effective as gray infrastructure projects.
