a) In addition to the minimum shoreline setback established by Planning Dept. Rule 11, the building setback should include a lateral safety buffer distance of 40' from the minimum shoreline setback, plus the distance equal to the average elevation of the cliff within the subject parcel, or, b) In addition to the minimum shoreline setback established by Planning Dept. Rule 11, the building setback should include a lateral safety buffer distance equal to the anticipated 100 years of erosion as determined by a coastal erosion study. This study, including a cliff stability analysis and/or a geological analysis, shall be conducted by a licensed civil engineer. This policy shall only apply to properties that are located within the Special Management Area and abutting the shoreline. For lots with sea cliffs over 40' with an average lot depth of two hundred feet or less, the shoreline setback line shall be determined by Planning Department Rule 11. The County of Hawai'i's current working definition of "top of cliff" is as follows: The "top of the pali" (top edge of the sea cliff) is defined to be the highest elevation along the seaward boundary of a property where the relative change in the slope of the terrain towards the sea is in excess of twice the general slope towards the sea of the terrain along this highest elevation and that the terrain: (1) has a general slope seaward of not more than 10%; (2) is reasonably safe for pedestrian access to and along its length; and (3) does not show evidence of being periodically exposed to natural elements, including, but not limited to, high surf, wind and rain, to the extent that the ground is essentially devoid of naturally occurring vegetation. Policy 20 To further protect coastal resources in the Special Management Area, review SMA boundaries in the Hamakua Planning Area and initiate appropriate amendments,- Consider mendments, Consider proximity to coastline and assess vulnerabilities to coastal changes,- Consider hanges, Consider including within the SMA boundaries appropriate near -shore riparian corridors. Consider SMA boundary amendments to further protect known recreational, historic, open space, ecosystem, beach, near -shore riparian, and/or marine resources as well as scenic views toward the coastline from the highway. Policy 25 Amend the Zoning Code Section 25-2-71 to require Plan Approval for commercial open area recreational uses in the "Important Agriculture Land" and "Extensive Agriculture" designations. Policy 27 Revise Planning Commission Rule 6, and/or to the Special Permit Application form (for Special Permits in the Agricultural District) to include clarity on the potential impacts to be evaluated in the application process and to clearly articulate the types of mitigating conditions that may be required. (HRS 205-6(c) and Planning Commission Rules 6-3(b)(5)(G), 6-7, & 6-8). 16 Hamakua CDP Guidance to Agencies
