    **Buffers in M-1 zoning shall increase from 50 to 75 feet when located adjacent to truck docks or outdoor storage areas. However, any development with an approved development plan, final plat or concept plan on file with the Department of Planning and Development prior June 1, 2001, which depicts a different buffer width shall be considered grandfathered .
    • For buffer width other than standard height structures the Board of Commissioners may increase the minimum buffer required as a condition for allowing additional height of development.
    • The Board of Commissioners may also establish or increase the minimum buffer as a condition of rezoning or as a condition to a Special Use Permit.
    • The Zoning Board of Appeals may increase the minimum buffer required as a condition to granting a Variance request.
    • Modifications in buffer width may be granted by the Board of Commissioners after receiving recommendations from the Planning and Development Director and Planning Commission and after a public hearing.
    • See Section 610-20.4.B - No structure shall be located less than 5 feet from any buffer
