Sec. 6-22.211.   Allowed Zones.
   Natural Resource Zones. Timber processing, as defined by the County Zoning Ordinance, is allowed by-right in the Timber Mountain (TM) and Timber Production (TPZ) zones. The provisions of this section do not apply to log storage yards in these zones.
   Industrial Zones. Timber processing, as defined by the County Zoning Ordinance is allowed by-right in the Heavy Industrial (HI) zone, and with a conditional use permit in the General Industrial (GI) zone. The provisions of this section do not apply to log storage yards in these zones.
   Zones Requiring an Administrative Permit. Temporary log storage yards are allowed subject to approval of a temporary administrative permit and compliance with the standards set forth below in the following zones:
   Agriculture (AG) Zones, limited to those Agricultural zones classified as Grazing or Other lands by the California Department of Conservation's Farmland Mapping Program. Parcels shall be located near state highways or truck haul routes that access the LNU Complex Fire area and outside of urban or congested areas.
   Standards. All temporary log storage yards shall meet the following standards:
   Application for Temporary Administrative Permit. The property owner or the property owner's authorized agent shall obtain a temporary administrative permit for the effective period. Written consent of the property owner is required in all cases.
   Site Plan Required. A detailed site plan meeting general architectural or engineering standards, legible and drawn to scale that shows all the proposed activities that will occur on-site, as well as the approximate location of each activity, shall be provided with the application for a temporary administrative permit. Partial site plans for a portion of a property may be submitted as long as a vicinity map for the entire property showing frontage streets, other uses and a cross reference of the area of the partial site plan is provided. All site plans shall show and label contours at maximum vertical intervals of five (5) feet; areas of proposed grading and fill; the width of access roads to and around parking, log piles and other piles, and buildings; and turnaround areas for fire and emergency services. Any change in the type of activity that will occur on-site or the location of any activity requires the owner or operator to apply for a new temporary administrative permit.
   Siting Criteria. To the extent practicable, temporary log storage yards shall be located on flat areas of the site that are already disturbed and in such a manner to decrease impacts to uses on surrounding properties.
   Approved Access. Temporary log storage yards shall have access onto a public road. If the public road is a county road, the approach shall be made with an encroachment permit approved by the Division of Public Works.

A biological report shall be furnished to the Department of Development Services demonstrating that the site does not contain wetlands and/or endangered or protected plants and animal species. A temporary log storage yard shall not expand without providing a site plan and a biological report to cover the expanded area.
   Fire Department/CAL-Fire Standards. Temporary log storage yards and the associated activities performed with them pose the risk of fire if fire suppression measures are not taken. The activities include working with and storing flammable materials in areas that have little to no water on-site and that are subject to fire. The County is setting the fire standards it believes are appropriate, but there are also state standards set out in California Fire Code Chapter 28 with respect to all log storage yards and incidental wood products stored there. Fire officials shall enforce the most stringent standards. Per California Public Resource Code, Section 4428, each site shall have a sealed box of tools that shall be located, within the operating area, at a point accessible in the event of fire. This fire toolbox shall contain: one (1) backpack pump-type fire extinguisher filled with water, two (2) axes, two (2) McLeod fire tools, and a sufficient number of shovels so that each employee at the operation can be equipped to fight fire.

   All piles shall be separated from all other piles by one hundred (100) feet and shall include on-site roads, driveways, and aisles as discussed above.
   All piles shall be monitored by a means approved by the fire marshal to measure temperatures. Internal pile temperatures shall be monitored and recorded weekly. A plan by the permittee for restricting and mitigating excessive temperatures shall be submitted with the application for the temporary administrative permit for review and approval by fire officials.
   Regular inspections of the temporary log storage yard by trained fire personnel shall be allowed and facilitated by the facility operator.
   Cutting activities shall comply with California Fire Code Chapter 35.
   Yolo County, Environmental Health Division Standards.
   Depending on the activities performed on-site, the temporary log storage yard may be determined to be a solid waste facility. The facility operator must provide access to the facility and provide for review of the activities occurring at the facility to the Local Enforcement Agency, County Environmental Health, to determine if there exists a requirement to register for a permit status as a solid waste facility in accordance with Title 14 of the California Code of Regulations.
   For sanitation purposes there shall be a minimum of one (1) portable toilet and one (1) handwash station at the facility for employee use. The portable toilet shall be routinely serviced by a licensed service provider.
