1   Lot size requirements in unsewered areas are also subject to provisions in the A District. Lot width for the CR and SC Districts applies to both the ordinary high water mark line and at the building line.
2   In the S District, where development exists on both sides of a proposed building site, building setbacks may be altered to more closely conform to adjacent building setbacks.
3   For the CR and CS Districts, buildings used primarily for agricultural purposes may exceed 35 feet. No other exceptions to the height provision are allowed.
4   Where feasible and practical, all roads and parking areas shall meet the setback requirements established for structures in § 152.500. Natural vegetation or other natural materials shall be required in order to screen parking areas when viewed from the water.
 
   (B)   Substandard lot. Any lot of record filed in the office of the County Recorder on the effective date of this chapter amendment which does not meet the area requirements of this subchapter may be allowed as a building site subject to approval of a shoreland impact plan and provided as follows.
      (1)   The lot meets all standards of the applicable zoning use district.
      (2)   The lot is in separate ownership from abutting lands.
      (3)   Except for lot area, all other sanitary and dimensional requirements of these districts are complied with insofar as practical (70% width and setback requirements).
      (4)   If in a group of two or more contiguous lots under a single ownership in the CS District, any individual lot does not meet the minimum lot width requirements of this section, the individual lot cannot be considered as a separate parcel of land for purposes of sale or development, but must be combined with adjacent lots under the same ownership so that the combination of lots will equal one or more parcels of land each meeting the lot width requirement of this section, or to the greatest extent practicable.
   (C)   Placement of structures.
      (1)   Placement of structures shall comply with the provisions of the Floodplain District.
      (2)   In the CS District, no structure shall be placed on any slope greater than 13% unless:
         (a)   Sewage treatment system facilities can be installed so as to comply with the sanitary provisions of this subchapter;
         (b)   Structures must be adequately screened;
         (c)   It must be proven that any potential or actual erosion or sedimentation problems do not exist and that adequate measures shall be taken to prevent them;
         (d)   Where bearing capacity is in doubt, soil boring samples must be taken; and
         (e)   Consideration must be given to color and architectural design (including roof slope and orientation), subject to the approval of the Planning Commission.
      (3)   In the CS District, the density of dwelling units shall not exceed one dwelling unit per lot.
   (D)   Nonconforming structures. All structures in existence prior to the effective date of this section which are permitted uses within the CS District, but do not meet the minimum lot area, setbacks or other dimensional requirements of this section shall be allowed to continue subject to the following conditions and exceptions.
      (1)   Any structure alteration or addition to a nonconforming structure which will increase the nonconforming dimensions shall not be allowed.
      (2)   Nonconforming signs shall be gradually eliminated over a period of time not to exceed five years from the effective date of this section.
