B. Prevention of Hazards. No facility shall present a hazard to surrounding residents or properties.
C. Drainage and Water Supply. No landfill may modify or prevent the flow of major natural drainage ways within the jurisdiction of the City of Denison.

D. Minimum Separation from Residential Uses. No non-putrescible landfill may be established within 300 feet of a developed residential or public use. No landfill involving the disposal of putrescible or septic wastes shall be established within one-fourth mile of any residential, public, or commercial zoning district; or any State of Federal Highway.

2. Wind Energy Conservation Systems (WECS).
A. The distance from all lot lines or any building or power line to any tower support base of a WECS shall be equal to the sum of the tower height and the diameter of the rotor. A reduction of this requirement may be granted as part of a Special Use Permit approval if the Zoning Board of Adjustment, after recommendation by the Planning Commission, finds that the reduction is consistent with public health, safety, and welfare.
B. The distance between the tower support bases of any two WECS shall be the minimum of five rotor lengths, determined by the size of the largest rotor. A reduction of this requirement may be granted as part of a Special Use Permit approval if the City Council, after recommendation by the Planning Commission, finds that the reduction does not impede the operation of either WECS.
C. Any tower or rotor shall maintain a distance of at least 100 horizontal feet from any structure, power line, or antenna located on another property.
D. The WECS operation shall not interfere with radio, television, computer, or other electronic operations on adjacent properties.
E. A fence eight feet high with a locking gate shall be placed around any WECS tower base; or the tower climbing apparatus shall begin no lower than twelve feet above ground.
F. The height of the WECS may exceed the height restrictions of the base district by up to 50%. The bottom tip of any rotor must be at least 10 feet above any area accessible to pedestrians.
