Communication 158 (2000) Bill 44 Page 2 According to the State Department of Health, Environmental Management Division, any development which exceeds 50 lots per parcel of record will require a central wastewater treatment plant. The preliminary subdivision layout for parcel 2 -5 -44:01 is tentative and can be revised as required to limit the number of lots to less than 50, with the disposal of wastewater through individual septic tank systems. The subject property is located in Zone "C" (areas of minimal flooding) as well as "Zone "A" (base flood elevations in a 100 year flood). The Department of Public Works requires the applicant to prepare a flood study, certified by a licensed civil engineer indicating the base (100 year) flood elevations within Flood Zone A. If the flood study reveals flood limits different from that of the FIRM, the applicant shall obtain a FEMA Condition Letter of Map Revision prior to construction plan approval. Upon completion of construction, a FEMA Letter of Map Revision shall be obtained prior to final subdivision approval. The applicant may consult with the Department of Public Works regarding a possible cost - sharing alternative to the flood study. A Drainage Master Plan was previously submitted for the proposed project and has since been modified by the Drainage Master Plan for the Puainako Street extension. Drainage casements will be created on individual lots to accommodate the project and to keep habitable structures out of flood hazard zones. The proposed project will be designed to incorporate natural slope and drainage patterns with no or minimal stream channel improvements required. Dry wells will be used to capture runoff' from the road and root's of houses so there will be no increase in runoff due to development. On -site retention will also be integrated into the subdivision to reduce potential for impacts to downstream properties. A five -acre lot has been set aside to serve as an amenity to the community and as a flood retention basin. The State Land Use designation is Agricultural. The LUPAG Map designation is Urban expansion, which allows for a mix of high density, medium density, low density, industrial and /or open designations in areas where new settlements may be desirable, but where the specific settlement pattern and mix of uses have not yet been determined. The Hilo Community Development Plan recommended that the area be maintained as A -1 a and A -20a, The ALISH system designates the subject property for Existing Urban Development. The Land Study Bureau designates the land as "E" or "Very Poor ". The U S Soil Survey classifies the soils as KaC and KaE, which consist of well - drained silty clay loams with rapid permeability, slow runoff and slight erosion hazard. Surrounding lands are zoned RS -10, A -la, A -10a, A -20a and CN -40 and include single family dwellings, small scale agricultural uses, and vacant land. In 1996, TMK 2 -4 -46: Por 7 (approximately 13.863 acres) was rezoned from A -I a to CN -40 for a commercial store, service station, and parking area. The area was also reclassified from the State Land Use Agricultural to Urban District. The Kaumana Estatcs Subdivision, zoned RS -15, is located approximately 600
