Application by Jeketrina Mysin: a six-unit condominium. The applicant property TMK: 750200660000,9,934 sq ft Zone: RM -1.5 We protest the major changes in site plans at such short notice. It is impossible to digest and respond to a 40-page addendum with less than two weeks before the Commissioners meeting. However,given what we understand to be the current proposition we have comment on actual on-site conditions,specifically related to deep excavation for an underground garage and swimming pool. SITE CONDITIONS Average soil depths in the PuaPua'a 2 Ahupua'a range from 50 to 100 centimeters(18.5"—37"). On the subject property below that is a sheet of almost solid basalt.The below-grade lava shelf extends across the entire southern face of the land protrusion currently identified as"Alii Point"and includes the adjacent lots to the south and west. (see Illustration 1) In addition to the underlying basalt layer there are multiple above grade lava domes on all three properties.The subject property adjacent to AIaKaLa includes a large lava dome that varies from grade to more than four feet high of solid basalt,which straddles our common property boundary(see illus. 2).Additionally,there is a lava dome on the north approximately 1/3 of the lot that protrudes an average of three feet above grade. PROPOSED EXCAVATION The below grade parking garage/building foundations will have to be excavated to a depth greater than 2.75 meters(9')encompassing the entire footprint of the building. Additionally,there will be a driveway ramp ranging from grade at AIN dr.to basement level. The swimming pool with a depth of seven feet lies in the far southwest corner of the lot,with a zero lot line setback.The pool is directly under the four plus foot high solid basalt dome that straddles our common boundary(see illus. 3). In addition,there will,of necessity, be trenches to accommodate electric,water supply,sewage,and surface runoff,which will crisscross the site, including under the basement and pool,to an unknown additional depth. DIRECT IMPACT The southwest corner of the lot's common boundary lava dome is planned to be excavated on the property line to level the site and dig down an additional seven feet to accommodate the swimming pool-spa combination. Literally inches on our side of the lot line is an electric supply power pole.The site has been inspected by a HELCO engineering representative,who stated that the planned excavation WILL cause the pole to fall. In addition,the pool/spa is required by code to be no closer than five feet from an electric power transmission source.Also adjacent to the lot line is a fifty-year-old Bougainvillea tree that is prized by our owners,and must remain undisturbed. INDIRECT IMPACT The excavation of basalt will require an excavator and rock hammer. I'm sure you all have experienced the noise created by breaking basalt during excavation procedures.The author(George Smith)was on-site engineering representative for Bowers&Kubota for the installation of two large fuel tanks at Ellison Onizuka Intl.Airport(see
