The City of Kansas City Missouri has 35 watersheds within its boundaries, with Line Creek being a rapidly developing watershed making it a high priority.  The City has begun to identify possible improvements for the 6 sub-basins within the Line Creek watershed and the following have been identified as high priorities due to significant flooding and stream bank erosion.

East Fork Regional Detention Basin – The Line Creek Master Plan Study has revealed that there are 48 flooding locations (East Fork Sub-watershed) downstream of a possible site for a regional detention basin.  A dry regional detention basin is being considered and could significantly reduce peak flows and mitigate the existing flooding problems downstream of the basin location. 

Old Maids – The Line Creek Master Plan Study has also identified several flooding locations in the Old Maids sub-watershed.  The proposed regional detention basin will provide temporary storage of runoff and lower the peak flows at the downstream end of the sub-watershed.  The significant flow reduction provided by the regional detention facility will prevent flooding downstream from the basin and reduce the need for additional improvements.  The proposed dry regional detention basin will have a storage area of 7.0 acres and as storage volume of 43 acre-feet.  The drainage basins reduce peak flows for the 100-year storm event by 37%.
