Green
A green St. Louis region will protect and enhance its natural systems while improving the performance of its water supply, stormwater, and wastewater infrastructure. Green strategies create networks for natural habitat, recreation, access to nature, flood mitigation, and water and air quality improvement.
Residents in communities across the region desire clean air, water, and access to open space and parks for recreation and enjoyment. They also expressed concern about flooding, soil erosion, and the increasing costs of sewer services. The Regional Water Infrastructure Assessment and Pilot Study process also show that water resource needs and costs will increase significantly in the coming decades as sewer districts and cities in the region replace obsolete infrastructure and improve water quality.
A healthy and well-functioning natural environment is critical to a strong economy and citizen quality of life. Investments in parks and green spaces can benefit communities. OneSTL partners will pursue strategies and policies for blue and green infrastructure investments that will save money for both governments and citizens while also providing enhanced water quality and reduced flood risk.
