      (1)   The property owner shall submit a stocking survey report to the County Assessor and the Assessor shall verify that the minimum stocking requirements have been met by the time required by Department of Forestry rules. The Assessor shall inform the Department of Forestry in cases where the property owner has not submitted a stocking survey report or where the survey report indicate that minimum stocking requirements have not been met;
      (2)   Upon notification by the Assessor, the Department of Forestry shall determine whether the tract meets minimum stocking requirements of the Forest Practices Act, being O.R.S. 527.610 through 527.810.

      (3)   The applicant shall provide evidence to the city that the domestic water supply is from a source authorized in accordance with the Water Resources Department’s administrative rules for the appropriation of ground water or surface water and not from a Class II stream as defined in the Forest Practices Rules, O.A.R. 629, 2003 Edition. For purposes of this division (E)(3), evidence of a domestic water supply means verification from a water purveyor that the use described in the application will be served by the purveyor under the purveyor’s rights to appropriate water.
   (F)   Siting and fire protection standards for buildings. The following siting and fire protection standards shall apply to all new buildings:

         (d)   On slopes greater than 40%, 150 feet beyond the primary firebreak.
      (6)   All chimneys shall be equipped with a spark arrester;
      (7)   If a building is to be located on a parcel that is within a fire protection district, the applicant shall provide evidence that the applicant has asked to be included in such district;
      (8)   If a building is to be located on a lot or parcel that is not within a fire protection district, the applicant shall either:
         (a)   Provide evidence that residential fire protection is provided to the property by contract and that such contracted service is comparable to that generally provided by fire protection districts in the rural areas of the county; or
         (b)   On site fire protection means are provided. Such means shall consist of:
            1.   Fire sprinkling system or systems;
            2.   On-site water storage and pumping equipment. Such a water supply shall consist of a swimming pool, pond, lake, or similar body of water that at all times contains at least 4,000 gallons or a stream with a minimum flow of one CFS. Road access shall be provided to within 15 feet of the water’s edge for fire fighting equipment and shall provide a turnaround for fire fighting equipment; or
            3.   Other methods which provide at least a comparable level of protection to that contained in division (F)(8)(b)1. and 2. above, and which are reasonable given site conditions.
      (9)   No building shall exceed a height of 30 feet except for fire towers.
   (G)   Fire safety design standards for roads. The following standards apply to all roads and driveways which access uses permitted under divisions (A) and (B) above, except for private roads accessing only commercial forest uses.

      (6)   Road grade.
         (a)   Road grades shall not exceed 12%, except that a maximum of 15% may be permitted on pitches less than 200 feet long.
         (b)   Variations from these standards may be granted by the fire service having responsibility for the area when topographic conditions make these standards impractical and where the local fire protection district states that their fire fighting equipment can negotiate the proposed road grades.
