- Lower Shoal Creek & Birmingham Bottoms Watershed Studies
Burns & McDonnell performed studies of the Lower Shoal Creek and Birmingham Bottoms watersheds for the Water Services Department of Kansas City, Mo. While the two watersheds share a common border, they are vastly different.
The Lower Shoal Creek watershed contains the transition from the upland areas to the floodplain of the Missouri River. This watershed is characterized by relatively steep stream banks caused by the down cutting of streambeds through the transition area. This watershed is partially developed with mostly residential housing. Lower Shoal Creek empties into the Missouri River floodplain along the northern edge of the Birmingham Bottoms area.
The Birmingham Bottoms watershed is in the protected area of the federal levee system and offers little physical relief. The development in this area consists of a burgeoning rail and freight terminal industry and agricultural pursuits.
Study efforts for the 22-square-mile study included data gathering, surveying, hydrologic and hydraulic modeling, public participation and completion of a prioritized capital improvement plan (CIP). Base flood elevations were determined for the 100-year event and floodways were established on the major tributaries. The hydrologic analysis and modeling of the enclosed systems were conducted using XP-SWMM, and the floodplain analysis was done using HEC-RAS.
The Lower Shoal Creek watershed study produced a capital improvements plan with nine distinct projects. Projects recommended routine maintanence, replacement of infrastructure, regional detention and preservation of green space. The capital improvements plan estimated $1.6 for all nine projects.
The Birmingham Bottoms watershed study recommend six projects having and aggregate $11.2 million of improvements. Improvements included replacement of infrastructure and regional detention.
