G.    Setbacks. The tops and toes of cut and fill slopes shall be set back from property boundaries according to the State Department of Natural Resources standards for safety of adjacent properties, and to prevent water runoff or erosion of slopes and to provide adequate reclamation slopes per subsection (J) of this section.

H.    Maximum Permissible Noise Levels. Maximum permissible noise levels shall be according to the provisions of the Kitsap County noise ordinance.

I.    Hours of Operation. Hours of operation, unless otherwise authorized by the director, shall be between 7:00 a.m. and 6:00 p.m.

J.    Slope. When reclaimed, no slope of cut and fill surfaces shall be steeper than is safe for the intended use, and shall not exceed one and one-half horizontal to one vertical for unconsolidated material such as gravel, and one-fourth horizontal to one vertical for consolidated material, unless otherwise approved by the director.

K.    Erosion Control. All disturbed areas, including faces of cut and fill slopes, shall be prepared and maintained to control erosion. This control may consist of plantings sufficient to stabilize the slope (as approved by the director).

L.    Drainage. Provisions shall be made to:

1.    Prevent any surface water or seepage from damaging the cut face of any excavations or the sloping face of a hill.

2.    Drain any surface waters that are or might be concentrated as a result of a fill or excavation to a natural watercourse, or by other means approved by the department of public works director.

M.    Bench/Terrace. Benches shall be back-sloped, and shall be established at not more than forty-foot vertical intervals, to control surface drainage and debris. Swales or ditches on benches shall have a maximum gradient of five percent.

N.    Access Roads Maintenance. Access roads to mining and quarrying sites shall be maintained and located to the satisfaction of the director of public works, to minimize problems of dust, mud, and traffic circulation.

O.    Overburden. Overburden shall only be removed to accommodate aggregate removal operations and related activities of this section.

17.170.065 Transition of uses from mineral resource and removal of the mineral resource overlay.

As an option to the requirements of Section 17.170.060 to reclaim a property(s) and extinguish a Washington State Department of Natural Resources (DNR) surface mining permit, the county may accept, review and approve development permits for uses consistent with the property(s) underlying zone. If a permit meets all applicable zoning, building, storm water, fire and other county codes, such permits shall be forwarded to the DNR to be reviewed as a reclamation plan. Upon receipt by the county of DNR confirmation of the closing of the surface mining permit for the property(s), the county shall include the property(s) in the next scheduled Comprehensive Plan amendment cycle. At this time, the county shall rescind the Mineral Resource Comprehensive Plan designation and zoning classification, reverting the property(s) back to their underlying zone and compatible designation.

17.170.070 Special provisions.

All plats, short plats, development permits and building permits issued for land development activities on or within five hundred feet of designated mineral resource lands, shall contain the following notice:

The subject property is within or near land in which resource activities are permitted and encouraged, including a variety of activities which may not be compatible with residential use for certain periods of limited duration. In addition to other activities, these may include noise, dust, smoke, visual impacts and odors resulting from harvesting, planting, surface mining, quarrying, application of fertilizers, herbicides and associated reclamation and management activities. When performed in accordance with state and federal law, these resource activities are not subject to legal action as a nuisance.
