Ankeny Stormwater Management Study and Master Plan

As part of RDG's comprehensive assessment of Ankeny’s stormwater management system, eighteen miles of stream corridors were examined by land, water and air. An extensive GIS analysis of the watershed conditions across the City and within its projected 2040 growth boundary was completed. RDG worked with the Iowa Flood Center to complete hydraulic modeling to evaluate existing and future conditions within key watersheds and around the community. The overarching goal was to recommend system improvements and evaluate policies to maintain a sustainable system of stormwater infrastructure for this community, which is expected to grow to nearly 90,000 residents over the next quarter-century.
