§ 18.20.420. Conditional uses.

A.

1.

There shall be a special two-hundred-foot riparian zone on each side of the Hydaburg River in which there shall be timber harvest by selective logging practices only, and the construction of logging roads will be prohibited.

2.

There shall be no timber harvesting or removal or construction of logging roads on land where the slope exceeds thirty-four degrees or seventy percent.

3.

All logs shall be yarded using a high-lead or similar cable yarding system. No log shall be yarded through waters of the watershed area. Tractor yarding is prohibited.

4.

Water crossings by logging roads will be prohibited. Rechanneling of the watercourse and channeling through a culvert are prohibited.

5.

All cutover areas shall be replanted before the second winter after logging, unless natural revegetation will be sufficient to prevent erosion of sediment into the waters.

6.

There shall be no application of fertilizer, herbicides, insecticides or other toxic substances.

7.

All fuel storage, trucks and other motorized equipment, except stationary yarders, shall be stored and maintained at an operating base established by the landowner or logging contractor outside the watershed boundaries. All fueling, lubricating and other maintenance, except for emergency repairs, shall be conducted at this operating base.

8.

The provisions of the Alaska Forest Practices Act of 1979, AS 41.17.0, et. seq., and the regulations promulgated thereunder shall be strictly complied with as minimum standard of water quality protection.

9.

A water quality monitoring program will be conducted by the landowner or logging contractor, the city and the Department of Environmental Conservation.

10.

Any operational activity causing impact to the aquatic system that is deemed potentially significant to the water quality will stop until the potential problem is remedied and adequate protective safeguards are put into place.

11.

There shall be a cleanup of all activities with removal of all foreign materials and waste out of the watershed area periodically and after work activities are completed.

12.

Timber harvest and removal, and forest management shall be planned around seasons to minimize potential impacts to surface run-off, sedimentations and erosion into the Hydaburg River.

B.

Minerals exploration and development are allowable conditional uses in the Hydaburg River watershed subject to the following:

1.

There shall be a special four-hundred-foot riparian zone on each side of the Hydaburg River in which minerals exploration and development are prohibited.

2.

Preliminary exploration activities shall be limited to airborne geophysics, chip sampling, limited soil and rock sampling, geochemical sampling, ground geophysics and other prospecting activities that do not require any ground vehicles or other equipment that cannot be transported in and out of the watershed by standard helicopter methods.

3.

Advanced minerals exploration shall be limited to trenching and/or core drilling activities that do not require any ground vehicles that cannot be transported in and out of the watershed by standard helicopter methods.

4.

Ingress and egress to facilitate bulk sampling, mine development and minerals extraction shall be accessed by utilizing existing road development to a transportation corridor outside the watershed.

5.

A water quality monitoring program will be conducted by the subsurface rights owner or developer, the city and the Department of Environmental Conservation.

6.

Any operational activity causing impact to the aquatic system is deemed potentially significant to the water quality and will stop until the problem is remedied and adequate protective safeguards are put into place.

7.

Storage of fuels, drilling solution or other potential pollutants within the watershed is prohibited.

8.

All equipment maintenance and worker camp facilities shall be located outside the watershed.

9.

There shall be a cleanup of all activities with removal of all foreign materials and waste out of the watershed area periodically and after work activities are completed.

10.

Mineral exploration and development shall be planned around seasons to minimize potential impacts to surface run-off, sedimentation and erosion into the Hydaburg River.

C.

Roads and logging roads are allowable, conditional uses in the Hydaburg River watershed subject to the following conditions:

1.

Roads and logging roads will be minimized.

2.

All roads and logging roads shall be designed to minimize erosion, slope failure and sedimentation.

3.

Surface drainage must be designed and constructed to avoid run-off from directly entering the Hydaburg River and impacting water quality.

4.

Public access to the Hydaburg River watershed above the municipal water intake shall be discouraged through design and physical barriers.

5.

Construction and maintenance shall be planned around seasons to minimize potential impacts to surface run-off, sedimentation and erosion into the Hydaburg River.

6.

There shall be no transportation corridor through the Hydaburg River watershed other than Forest Highway 13.

7.

Only one water crossing of the Hydaburg River will be allowed above the existing "in town" road crossing, that crossing will be for Forest Highway 13 part of the bridge, fill or abutment in the waters of the Hydaburg River.

8.

Any operational activity causing impact to the aquatic system that is defined potentially significant to the water quality will stop until the potential problem is remedied and adequate protective safeguards are put in place.

9.

A water quality monitoring program will be conducted by the landowner or contractor, the city and the Department of Environmental Conservation.

10.

There shall be a clean-up of all activities with removal of all foreign materials and waste out of the watershed area periodically and after the work activities are completed.

11.

All fuel storage, trucks and other motorized equipment shall be stored and maintained at an operating base established by the landowner or logging contractor outside the watershed boundaries. All fueling, lubricating and other maintenance, except for emergency base.

12.

Except as provided in subdivision 7 of this subsection, there shall be a special four-hundred-foot riparian zone on each side of the Hydaburg River in which roads and logging roads are prohibited.

D.

Residential development is an allowable conditional use in the Hydaburg River watershed subject to the following conditions:

1.

There shall be a special four-hundred-foot riparian zone on each side of the Hydaburg River in which residential development is prohibited.

2.

Lot shall be no less than one acre per residential unit.

3.

All residential units shall be connected to the city's sewers at the owner's expense.

4.

All stormwater run-off from roofs, roads and yards shall be collected and diverted to a point down stream from the city water supply intake point.

E.

Other commercial or industrial uses not referred to in this section are prohibited.
