(A) Purpose and intent. The Watershed District is intended to preserve and protect the potable water reserves available to the city. The major responsibility in the management of watershed areas is the control of those factors which could contaminate or pollute the water. Agricultural, residential, commercial, industrial, or other urban land uses are incompatible with the concept of watershed conservation.
(B) Uses permitted. In the Watershed District, no building or structure or land shall be used, and no building or structure shall be erected which is arranged, intended, or designated to be used for other than one or more of the following uses:
(1) Water reservoirs;
(2) Water treatment plants;
(3) Water pumping stations;
(4) Water wells;
(5) Snow and water gauging stations;
(6) Flood control and drainage structures;
(7) Hydroelectric generation facilities; and
(8) Other similar uses not listed above which meet the “Purpose and Intent” provisions of this section of the ordinance and would be no more objectionable than those uses listed above. The Director of Planning shall make a “Planning Determination” in this matter subject to appeal to the Planning Commission (See § 8.12.220(A)(2)).
(C) Permitted accessory uses and structures. Small wind energy system and accessory uses and structures customarily incidental and subordinate to the location, function, and operation of permitted uses and structures.
(D) Conditional uses and structures. In the Watershed District, other uses and their accessory uses may be permitted, subject to securing a Conditional Use approval in each case as provided for in this chapter (See § 8.12.200). In determining whether to grant a Conditional Use, the Planning Commission shall:
(1) Examine the petitioner's proposal for its impact on ground and surface water supplies and stream pollution, the effects of land development on surface water runoff and erosion, and the alteration of natural drainage patterns;
(2) Solicit the technical advice of affected and knowledgeable public agencies, including but not limited to the City Department of Public Utilities, the U.S. Soil Conservation Service, the U.S. Geological Survey, the U.S. Corps of Engineers, the Alaska Department of Environmental Conservation, the U.S. Bureau of Land Management, and the Alaska Department of Natural Resources, and any other affected entity; and
(3) Impose any conditions which it deems reasonable for attainment of the objectives of this district.
In addition, the Commission may require the petitioner to submit engineering and other technical studies that will show the impact of proposed development on the hydrology of the affected area within the Watershed District.
(E) Minimum lot size. 10,000 square feet.
(F) Minimum lot width at front lot line. 70 feet.
(G) Minimum yard requirements.
(1) Front yard. 25 feet.
(2) Side yard. 15 feet, except where a property adjoins a residential district or a corner lot faces a right-of-way there shall be a 20-foot side yard.
(3) Rear yard. 25 feet.
(H) Maximum lot coverage. 50%.
(I) Maximum height of structures. None.
(J) Special provisions. The following special provisions apply to all land uses within the Watershed District:
(1) Any use is prohibited which causes or may reasonably be expected to cause excessive noise, vibration, odor, smoke, dust, or other particulate matter, humidity, heat, or glare at or beyond any lot line of the lot on which it is located. “Excessive” is defined for these purposes as a degree exceeding that generated by uses permitted in the district in their customary manner of operation, or to a degree injurious to the public health, safety, welfare, or convenience;
(2) The storage of flammable materials, hazardous materials, or toxic waste on-site shall be allowed only in strict compliance with federal, state, and local laws and regulations;
(3) Materials shall be stored and grounds shall be maintained in a manner such as will assure access by fire equipment; and
(4) Materials shall be stored and grounds shall be maintained in a manner which will not attract or aid the propagation of insects or rodents or otherwise create a health hazard.
