The City of Springfield and Springfield Utility Board (SUB) work together to make sure Springfield's drinking water is safe and high quality. One way to do this is through the Drinking Water Protection (DWP) Overlay District, which is a type of zoning district. The City and SUB propose a Zoning Map Amendment to apply the Drinking Water Protection Overlay District to property recently added to the Springfield urban growth boundary (UGB). The Zoning Map Amendment would establish the drinking water protection requirements of the Springfield Development Code (Section 3.3-200) in these UGB expansion areas. The UGB expansion areas are generally located in: (1) North Gateway in northwest Springfield; (2) Mill Race in south Springfield; and (3) Willamalane Park Properties along north Springfield (see Vicinity Map). To find if a specific property is within the area covered by the DWP Overlay District, use the interactive location map and select "Natural_Features_Hazards" on the layer list (click on an icon that looks like three stacked squares), click on the arrow next to it to expand the list, and then select "Wells".
