Tulsa District Regulatory Permits for Public Comment

PURPOSE:  The purpose of these public notices are to inform you of a proposal for work in which you might be interested and to solicit your comments and information to better enable us to make a reasonable decision on factors affecting the public interest.

SECTION 10: The U.S. Army Corps of Engineers is directed by Congress through Section 10 of the Rivers and Harbors Act of 1899 (33 USC 403) to regulate all work or structures in or affecting the course, condition, or capacity of navigable waters of the United States.  The intent of this law is to protect the navigable capacity of waters important to interstate commerce.

SECTION 404: The U.S. Army Corps of Engineers is directed by Congress through Section 404 of the Clean Water Act (33 USC 1344) to regulate the discharges of dredged and fill material into all waters of the United States.  These waters include lakes, rivers, streams, mudflats, sandflats, sloughs, wet meadows, natural ponds, and wetlands adjacent to other waters.  The intent of the law is to protect these waters from the indiscriminate discharge of material capable of causing pollution and to restore and maintain their chemical, physical, and biological integrity.

Location:  The proposed project is located in the Southwest 1/4 of Section 7, Township 21 North, Range 14 East, in Owasso, Tulsa County, Oklahoma.  The project site can be found on the Collinsville, Oklahoma 7.5 Minute USGS Quadrangle map at Latitude 36.307585 North and Longitude 95.85943 West.

 Purpose:  The basic purpose of this work is to reduce flooding on-site and downstream as part of the 2005 Owasso Master Drainage Plan.  The project is not a water dependent activity.  The overall purpose of this work is to construct a stormwater detention facility within this specific drainage area that would reduce flooding in the unnamed tributary of Ranch Creek.

Description of Work:  The applicant proposes to place soil excavated from on-site within the above listed aquatic resources for the construction and grading of a stormwater detention facility on City of Owasso property.  The total earthen fill would equate to 8,210 cys within the above identified aquatic resources below their associated OHWM.

The proposed detention facility would be excavated, include construction of a perimeter berm, and incorporate both wet and dry area detention.  Normal and high flows from the unnamed tributary (FS-3) that currently transition along the southern property boundary would be redirected into the detention facility near the southeast basin corner.  The lower portion of the basin is designed as wet detention and the unnamed tributary would be allowed to enter and exit the basin unrestricted.  The lower portion of the basin would be excavated to retain approximately 2 feet of standing water.  Six reinforced concrete boxes would be constructed in the southwest corner of the basin and serve as the controlled outlet structure.  Flows from the basin would reenter the undisturbed downstream section of the rerouted unnamed tributary.  The upper portion of the proposed basin would be graded to drain and be used as dry detention to temporarily retain stormwater.  Recreational facilities such as soccer fields and day use areas are planned for development in the dry detention area of the basin.  Earth disturbance anticipated with basin construction would include excavation, berm construction, clearing, and shaping of the basin.
