HIRAYAMA:Yes, metal building. The outside is going to be metal, metal siding, metal building. SIRACUSA:Okay, thank you. GRAHAM:All right. Thank you. Do we have any other questions from the Commissioners? Mr. Fuke, could I ask you a drainage-related questions? FUKE:Sure. GRAHAM:I know in the previous application we had today we were dealing with drainage concerns and all. And I know that one of your conditions here is that, and one of our general situations is that any development-generated runoff should be disposed of on property. Since the elevation here is relatively low, relative to sea level and all, I was just wondering if you couldgiveusanideaofhowyoullactuallyaccomplishthat,youknow,onthegrounddisposing of the runoff, and if theres any way that the County Department of Public Works could ever actually, can verify that its successful, whats done and all. FUKE:Sure. Generally like theres going to be like two separate drainage report requirements. One is going to relate to the site itself. Cause if this rezoning goes through and he submits his plans for a building permit, in conjunction with the submittal of the building permit application he has to submit civil drawings that show how the on-site drainage will be disposed of. And, generally, in situations like that, and this situation here, the on-site generated runoff will be handled through a system of drywells. The drywells would have to be reviewed and approved by not only Public Works Department but the State Department of Health under the Underground Injection Control System. The other sets of construction plans that hes going to have to prepare would be the construction plans as required by your staffs recommendation, construction plans for your curb, gutter, sidewalk section along Manono Street. And so when you have your curb, gutter, sidewalk section, theres also going to have to be provisions for accommodating the drainage system and probably they will have to install a system of drywells, you know, like within the road frontage to accommodate the additional water in that area. So both plans would have to be prepared, have to be reviewed and approved by the County, and subsequent permits by the Department of Health under the Underground Injection Control Permit System would have to be issued. GRAHAM:Okay. And then maybe like kind of like on the ground since youre 20 feet roughly above sea level of something like that, so probably if you drill down 20 feet you would actually kind of hit a water table or something. And so what youre effectively doing is taking any extra runoff and getting it down below the level of the surface, and somehow it will dissipate laterally or into the water table enough to keep up whatever rains coming down or something. Is that the idea? FUKE: Correct, yeah. And so like through UIC and as well as the MPDS permit they both govern water quality as well. So if, for example, the proposed zoning wouldnt allow it, but say if you have an Industrial zoning and you have like an auto body fender shop or something that may cause like gasoline spill or something like that, then your catchment system would also have to be different to be able to protect the groundwater in that area. 7EXHIBIT B
