Stantec CENTERVILLE SURFACE WATER MANAGEMENT PLAN 1.0 EXECUTIVE SUMMARY The City of Centerville, located within the Rice Creek Watershed District (RCWD), is a rapidly growing community of 2.6 square miles. Currently, about 80% of the City is developed. Although complete development in the comprehensive plan is proposed to be staged over the next 20 years, development pressure will likely result in the rapid development of the remainder of the City. Because of the impending development that will occur in Centerville, the management priorities of the City have focused on issues surrounding development, such as installation of proper detention facilities, erosion and sediment control of new construction sites, providing adequate storm sewer capacity, and meeting water quality requirements. The RCWD has in the past regulated new developments occurring in Centerville through the District's permit program. However, at this time, the City recognizes that several issues surrounding new development and water resource management are best implemented by the City, as the local entity with the most to gain or lose with several of these issues.
