Are there any exceptions to the restrictions within the Karst/Sensitive Environmental Feature setbacks?
On a lot existing on February 17, 2010, where there is no feasible alternative outside of the Karst/Sensitive Environmental Feature setback, a principal residential structure and/or drainfield for such structure can be located in a setback area if a geophysical study and/or drainfield is provided, such structure and/or drainfield is located as far from the Karst/Sensitive Environmental Feature as is feasible, and the geophysical study shows that subsidence does not pose a serious risk to public health or safety or to the residents of the structure. However, no accessory structures shall be permitted to locate within the setback area.
