5) U.S.D.A. Natural Resources Conservation Services Soil Service Report soil type: The U.S.D.A., Soil Conservation Services Soil Survey of the Island of Hawaii classifies the soil of the subject property as Keaukaha extremely rocky muck with 6 to 20 percent slopes (rKFD). The Keaukaha series consists ofwell-drained, thin organic soils over pahoehoe lava bedrock. Permeability is rapid, mnoff is slow, and the erosion hazazd.is slight. 6) Land Study Bureau soil rating: The subject property is designated,as an urban azea and was not given a soil rating. 7) Existing drainage ways or improvements: There are no existing drainage ways or improvements in the vicinity of the subject property. 8) Air/noise/water quality: The air quality of the subject property is primarily affected by pollutants derived from the volcanic emissions from the ongoing Kilauea eruption. Other sources of air pollution affecting the project site include exhaust emissions from neighboring streets and the airport. In general, however, the ambient air quality of the project area meets all federal and state standards as evidenced by its designation as an "attainment" area by the State Department of Health, Clean Air Branch. Existing noise levels in the vicinity of the subject property aze influenced by vehiculaz traffic on neighboring streets as well aircraft noise from the Hilo International Airport. Noise level readings taken on property fronting on Kanoelehua Ave. for the Draft Environmental Assessment, Hilo International Airport Project No. AH1011-03 by Y. Ebisu & Associates in September 2001, indicated noise levels less than 60 DNL. These noise readings should reflect higher noise levels than the subject property due to closer proximity to the airport runway and on a major thoroughfaze. Nevertheless these noise levels are considered to be "moderate exposures" by federal standards and well within guidelines for- commercial, industrial and other non-noise sensitive land uses. The closest water body to the project azea is the Waiakea Pond, approximately 2,000 feet west of the project site. As such, the proposed change of zone is not anticipated to have any impact on water quality. 9) Existing archaeological, cultural or historic sites on National Register or Hawaii Register: Due to the development and use of the subject property for single family residential purposes since 1929, it is highly unlikely that any archaeological, cultural or historic sites are present on the property. A letter dated September 4, 2008, from the State Historic Preservation Division confirnis that no historic properties will be affected by this project because previous grubbing/grading and residential development/urbanization has altered the land. 10) Existing floraUfaunal resources (any native or exotic plants; any listed or candidate for endangered species): The entire pazcel has been previously graded and developed for single family residential use since 1929. There is no habitat that would appear valuable for native terrestrial or aquatic species.
