County Growth Zones The four County Growth Zones generally identify different levels of development primarily based upon their ability to be served with sanitary sewer infrastructure, largely established by the 2016 South Sarpy County Sanitary Sewer Study, prepared by HDR, Inc. However, other criteria were also considered in establishing varying intensities of development: proximity to major transportation routes, existing land use densities, environmental sensitivity, agricultural utilization, etc. Utilizing the characteristics of these and other important factors, each of the different policy areas will be applied to relevant portions of Sarpy County. The result of the concept will be a broad based policy statement designed to encourage growth and development into specific areas of Sarpy County based upon a well-designed management approach. The County Growth Zones defined for Sarpy County are: Conservation Zone Urban Reserve Zone Urban Development Zone Rural Development Zone
