7581ots mostly 20,000 square feet or less in size innmediately mauka of Highway 130, <br />the DHHL Maku'u Makai parcels consisting of approximately 500 acres primarily <br />mauka of Beach Road and SE of Hawaiian Paradise Park, amd the DHHL 100-acre <br />Keonepoko Nui parcel makki of Hwy 130. This restriction would also impact the State's <br />Keonepoko Farm Lots north of Kahakai Blvd. This proposal in the CDP would <br />significantly increase the cost of building a home in these areas because the owner could <br />not use a cesspool or a typical septic system, which has a holding tank and a leach Feld. <br />The owner would need some type ofself-contained mini treatment plant. It is very <br />unlikely that a centralized wastewater treatment system will be developed in this area, <br />and this type of system is also very costly. <br />The necessity of such requirements to protect drinking water is questionable. Current <br />DOH rules do not allow new cesspools and septic systems within a 1000' radius of wells <br />used for public drinking water. DWS has several wells, however, dating from before <br />these DOH rules, which are surrounded by homes on cesspools, such as a well near <br />Gilbert Carvalho Parkin Hilo. The water in these wells is regularly tested and has not <br />Shawn any microbial contamination. <br />It is possible to create a similar aquifer protection area that would protect the source of <br />water for the current DWS wells be#ween the Ainaloa subdivision and Pahoa, and more <br />wells that might be drilled in this general area, without causing problems for <br />homebuilders on DHHL land. The DWS wells are located just mauka of Hwy. 130. <br />Irrunediately mauka of these wells is a 5,127-acre State parcel that is part of the Puna <br />Forest Reserve, and Wao Kele O Puna, owned by OHA. Under current plans, both <br />would remain as nahiral areas. The Planning Director therefore recommends amending <br />§2.3.3.d. to read as follows: <br />By agency agreements and control of zoning and building <br />permits, ensure that a corridor of the Puna watershed at <br />Least two miles wade ~J}::cc~ including the Wao Ke.Ie O Puna <br />forest area and~~e-Qe~ean ~e t-h~a~~re~a~ State Lands <br />mauka of Highway 130 between the Ainaloa subdivision and <br />' Pahoa is protected from uses that might contaminate <br />-7- <br />
