Hull completed a subsurface exploration and evaluation of the geotechnical conditions of the proposed 2,400-foot long control levee that will protect a new residential development in the Village of South Bloomfield, Ohio.
The intent of the Class I Levee was to address flooding associated with the overflow from the adjacent Scioto River to the west.
A slope stability analysis was performed pursuant to OAC Rule 1501:21-5-04(A) and the U.S. Army Corps of Engineers Levee Design Manual in critical areas along the levee that were considered most vulnerable to slope failure. The underseepage and substratum hydrostatic pressures beneath the levee embankment were also considered due to the presence of the granular (pervious) stratum underlying the levee.
The work was prepared in conformance with the Final Design Report requirements of Chapter 1501:21-5-04 of the OAC Rules for levees (effective December 9, 1999). It was recognized by Hull that the OAC Rules were being updated during the work, however, through discussions with ODNR was able to complete the project without complications of the rule change.
