GROUP NO. V
(RESTRICTED SOIL)
(a) Light to dark colored, moderate to poorly drained soils in alluvium on flood plains, water table high most of year and subject to flooding.
(b) Severely limited for home site, questionable ground bearing for foundation.
LIMITATIONS
Building any structure is not permitted in a designated 100-year flood plain. The elevation of the 100-year flood plain must be provided and certified by a State of Ohio registered professional engineer. The owner must provide a certified foundation design drawing by a State of Ohio registered professional engineer for building foundations outside of the 100-year flood plain for groups (a) and (b) above. To build on strip mine soil sub grade (b), bearing capacity tests and recommendations for type foundations are required, and shall be provided by State of Ohio registered professional engineer.
