GOMES:Very good, very well, yes, you did.
<br />SPRINGER:So I wonder in a situation like Hilo, which hundred year floods every
<br />couple years, if this formula is in a sensibility is properly applied to circumstances such as this.
<br />YUEN:I have a concern about this, not so much on a -, I hate to do things on an
<br />individual basis on this lot, on a lot by lot basis, but the very fact that -, you see these floodways?
<br />They are established based on historical precedent, that this is where -, this is the extent of the
<br />active floodway based on rainfall we've had in Hilo in the past. And it's not, they're not
<br />engineered in the sense that somebody has really done a detailed study, it's mostly done, you
<br />know, from the standpoint that this is what happened last time and so this is where we're
<br />mapping that it's going to happen next time. As you, as we develop and develop subdivisions
<br />and develop roads and make these more impermeable surfaces, we are creating a condition
<br />where when you get beyond the ten year event, then more water is going to run off into the
<br />floodways and potentially increase the severity, not that the rainfall increases for the hundred
<br />year event but the amount, the area that becomes a floodway during a hundred year event may
<br />increase. And I have to say I don't know that we really are dealing with this. So it's a concern.
<br />It's not something that I would advocate doing, you know, we don't deal with it on this
<br />application, but it's something that is, that we have to think about as a community.
<br />FUJIKAWA:Okay.
<br />SPRINGER:I have a concern then if there is increased commercial activity there
<br />resulting in a decrease of, a net decrease in permeable area, that you've got this cumulative effect
<br />and I'm wondering if that's taken into consideration when calculating for 24-inch pipes being
<br />sufficient to remove water from a newly resurfaced area or not.
<br />YUEN:Well, I can't, obviously, from my questions, I don't have a lot of details
<br />about what happened on this particular piece of property. As a general concern or a general
<br />question, yes, cumulatively as we develop as a community in Hilo or in Kona, what has
<br />historically been floodways may not handle the water that goes through them. I mean, is this
<br />little, is this commercial lot going to be, make a big difference? Probably not. So we need to
<br />deal with this lot and the drainage specifically on this lot. There is this bigger issue that I think
<br />you're asking about.
<br />SPRINGER:Okay. One more question on this. If not on this little lot, how do we
<br />address this so that the cumulative effect of all these little lots is to the greater benefit of the
<br />community rather than detriment?
<br />YUEN:I think in the long term we need to look at the floodways and see if they
<br />are adequate. What we've been trying to do on the zoning level is keep people out of the
<br />floodways as much as possible, and out of the floodway fringes and out of the flood plains, and
<br />so we have, if you look at the previous application for the Waiakea Uka Subdivision, we have
<br />our standard, we have a standard condition in zoning that there be no construction within the
<br />flood plain. Actually, you know, without that, the Flood Code does allow construction within
<br />the flood plain. You just have to elevate a little bit. And that's another issue because okay, are
<br />25
