Background:
Indian Nation Council Boy Scouts of America (Boy Scouts) contacted the City requesting assistance with a drainage concern. The land has changed over the last 100 years. It was a strip mine in the 1950's. Since then, a portion has been reclaimed for beneficial use. The northeast portion is currently owned by Northeastern State University, NSU. NSU appears to have started reclaiming the land around 2002, according to aerial photographs. Prior to the strips mines Broken Arrow Creek was originally west of the Boy Scouts property. Currently Broken Arrow Creek has changed course and now flows through the pond on the Boy Scouts Pond. The date of the change in flow direction is unknown. However, the 1995 aerial shows the connection between Broken Arrow Creek and the Boy Scouts pond already established.
The outflow structure of the Boy Scouts pond is a low water crossing. A low water crossing is a structure that is designed to overtop before the 1% chance (100-Year) rainfall event. The structure is calculated to overtop by about 5 ft - 9 in during a 1% chance event. The Boy Scouts state the outlet structure does overtop several times a year. This overtopping has caused erosion concerns around the structure. The Boy Scouts have previously repaired some damage and are requesting assistance with the current conditions.
New Orleans St. is calculated to overtop by about 11 inches during the 1% event storm. City staff does not have records of New Orleans St. overtopping in the last 38 years.
This area is in a FEMA regulated floodplain and a blue line stream governed by the United States Army Corps of Engineers.
