V. INFRASTRUCTURAL CONSIDERATIONS A. Water The subject site is already serviced by a County approved water meter. As the demand should be no different than a standard family which should use no more than a maximum average daily consumption of 400 gallons per day, no additional meter and/or water service is being requested for this proposed activity. B. Wastewater The existing dwelling is served by a septic system approved by the State Department of Health. This system was predicated upon the use of the existing 4-bedroom dwelling_ As such, whether for a B&B or a conventional 4-bedroom dwelling use, the wastewater demand should presumably be the same. C. Drainage According to the US Corps of Engineers Flood Insurance Rate Map (FIRM), the area of the requested use is situated within Zone X. Said designation refers to areas determined to be outside of the 500-year flood plain. The Applicant has not observed any significant runoff or erosion in the recent past on the subject site. As noted earlier, no physical ground improvements— aside from the normal maintenance and planting of additional landscaping typically associated with the residential use of the subject site are being proposed. However, if any improvements are made requiring significant drainage improvements, appropriate clearance from the County Department of Public Works will be secured prior to proceeding. D. Access and Traffic Implications Access to the project would be from the end of Nani Kailua Road, a County road with a 20-foot wide pavement and full shoulder improvements within a 50-foot wide right-of-way. Beyond that point and mauka of Hienaloli Road, Nani Kailua Road continues via a 50- foot wide road and utility easement to the gated Ka_ainapono Subdivision. The easement has a 20-foot wide road with full shoulder improvements, similar to the lower portion of Nani Kailua Drive. The 8
