H. Water and Coastal Resources The subject site is located over a mile from the coastline. As such, coastal impacts resulting from discharge of drainage systems from the site should not be significant. Being a non-coastal property, no coastal access will be affected, As there is no sewer line in this area, individual wastewater system meeting with the approval and requirements of the State Department of Health — more than likely septic — will be installed by the respective lot owners. Thus, this should further reduce potential adverse groundwater or nearshore water impacts resulting from this project. Further as noted earlier, prior to the installation or use of any drywells on the site to address on-site drainage concerns, the appropriate UIC permit from the State will be taken. At that time, impacts to water and coastal resources will be carefully examined. Noise, Air Quality, and Dust The existing background ambient noise level in this area is wind, foliage, birds, and the like. However, the significant manmade noise is influenced by the traffic associated along the Mamalahoa Highway. The traffic noise level, during the AM peak, could approach 55 Ldn. To mitigate this noise to the project, the applicant may provide appropriate landscaping —without compromising sight distance- along that portion of the proposed lots adjacent to the Highway. There will also be short-term noise impacts during the construction phase. To mitigate this impact, the development of this project— particularly the site work -will be limited to daylight hours and on weekdays. Contractors will also be required to comply with established State Department of Health guidelines and standards relating to noise and emission controls. The proposed development should not generate any direct air quality impacts. As the project itself is not expected to have uses that generate adverse air pollutants. the only discernible air quality impact would be associated with vehicular traffic to and from the site. While the added traffic will have an impact to the ambient air quality, the impact should not be significant. This is due in part to the higher EPA standards for vehicular air emissions and the prevailing tradewinds. 9
