impacted by enterococcus. Samples near the entrance to the beach park and pavilion were found to have the highest enterococcus levels, which exceeded the limit for recreation waters. The shallow marine cove fronting the beach park was predicted to have the highest bacteria levels due to its proximity to the existing leach field. However, samples from this location were found to have the lowest enterococcus levels, well below the limits allowed for recreational waters. Additionally,a dye test was conducted and originated at the comfort station's septic tank and no dye was observed in the adjacent marine waters through the investigation period. The study concluded that the IWS appears to be adequate for low to normal usage periods, however it may be undersized for the estimated weekend use. The study further provided options to the Department of Parks and Recreation on other possible wastewater systems. Based on the water quality investigation, dye test and the IWS capacity for normal day-to-day flows, keeping the existing IWS was recommended. Additionally, further investigation was recommended during high usage periods and increasing the frequency of pumping was also recommended. Both will help to determine if the existing IWS is functioning properly during high usage periods and determine an approximate high usage population. At this time the Department of Parks and Recreation will provide a holding tank for toilet waste while continuing to use the existing IWS for sink water. Based on the preceding, the Planning Director is recommending a condition of approval requiring the applicant to more frequently routinely pump the existing septic system (once every three months to once a month during high usage periods) and provide a holding tank for toilet waste while continuing to use the existing IWS for sink water. There were no professional surveys conducted of the floral or faunal resources for the subject property, however the applicant does not believe that any rare or endangered floral or faunal resources are likely to be found within the subject property due to the long- developed use of the subject property for park activities. According to the State Department of Land and Natural Resources, Division of Forestry and Wildlife (DOFAW) there are several state-listed species that could occur at or in the vicinity of the subject property including the Hawaiian Hoary Bat(`Ope`ape`a), Hawaiian Duck(Koloa Maoli), Hawaiian Coot (`Alae ke`oke`o), Hawaiian Goose (Nene), Hawaiian Sea Turtle (Honu), Hawaiian Monk Seal (Ilio holo i ka), Hawaiian Hawk (`Io), Blackburn's Sphinx Moth, Hawksbill 7
