led to only six-inch change in shoreline erosion. I think that's normal beach process that's going to have to play itself out. Mr. Pieri. PIERL The area above the pahoehoe shelf itself may have only had that foot or two-foot or six inches or whatever erosion in the past 40 years. You can notice that by the fact that the palm trees are still there. The south end that we are concerned about, for 35 years there was some huge boulders that sat in front of that area. The state mandated that those boulders be removed. Those boulders protected that area just as the boulders that remained. Because they were on the county side of the property line, we weren't required to remove those. But those boulders protect the beach. The boulders that were on the end and the concrete overpourI must say there was a concrete overpour there behind the boulders protected the south end of the property for all that time. The other thing is is there were two sections of low rock walls in the northern half of where the proposed structure is to be. Those walls also protected from erosion for 30-plus years until tsunami of 2011 dislodged one of them and then took it out on the shelf, and it had to be removed. The other one remained in place, again,which was only about a 16-foot section, but remained in place until the state required it be removed for a shoreline certification. So reason that there hasn't been that erosion, or that there's only been six inches of erosion, is because we haven't, you know, because it was protected prior to that, and since then we haven't had any of those major, except for Hurricane Barbara, August of 2019, we haven't had any major occurrences that will wash the material away, but,you know, with sea level rise (indiscernible— echo) that's going to happen. VITOUSEK: So, I hear you there, I hear you there. All of that is information that should be included in the erosion study that would justify the need for shoreline hardening, because the erosion study that was provided to us indicates that there is no erosion happening, and that the shoreline is stable, and that there is no need in my opinion to harden the shoreline. A further erosion study would also indicate whether there has been cross-shore drift from south wells pushing that sand up into the project area because, you know, and you may not see it, but this area of sand in front of the Kona Reef is one of the bigger sand deposits in Kona. If you look at the Google Earth, you'll know what I'm talking about; there are not a lot of areas of sand deposits on the Kona coast, and this is one of them, and it needs to be protected. The sand deposit identified underneath the imported fill is equally important in maintaining beach processes. So, you know, with that, I would like to entertain a motion from any of the commissioners so that we can move forward to discussion. Commissioner Van Pernis. VAN PERNIS: First, I'd like to remind Mr. Roy that the lawn is an improvement just like the buildings are, and if this affects that improvement, it's legitimate. Secondly, I would like to, before making a motion,point out as a former Kailua Village Design Commissioner, this building is, or this project is, essentially commercial within that area, and all the other, or there are many other commercial areas, there are walls. I am going to make a motion to defer this matter generally, not to a specific date, generally until the Planning Department, through the commission, and the applicant have had adequate opportunity to provide all the updated information necessary for recommendation. I don't think the application is complete and current, and I think the Planning Department has said that there is 22 EXHIBIT A
