SUEDA:So, well, not at this time. However, we will abide by this; and what it would be is the series of drywell that we’ll be providing on the site. And I think we still have this so-called Clean Water Act that we need to abide by. So whatever the governmental agencies require, at the time, will be completed and done to dispose of any surface water in this parking lot. GRAHAM:I’m just thinking that we are also the governmental agency and it’s sort of our responsibility, too, to keep the water clean. So, Chris, do you have any thoughts on this? And I’m sure you can understand what my concern is, and I just don’t like to pass the responsibility on for something this size this close to the ocean as if it’ll all just be taken care of downstream in time here. YUEN:Well, you mean, are you concerned about nutrients from surface water that gets into the groundwater? Because the normal conditions of the development would require that they have drywells that take the runoff water and put it into a drywell about 20 foot deep; and then it’s rock, and that’s what would happen.You wouldn’t have to take care of every single, the Public Works requirement is for the 10-year, one-hour storm, which is roughly a two-inch an hour rainfall, which is a considerable rain. And that is a condition of the SMA permit. It’s also something that the Public Works Department would make them do as a matter of normal course, even outside the SMA, when they submit their civil drawings for this development of the site. ALAMEDA:Mr. Graham? GRAHAM:Yeah. My concern is that, like I think Public Works is going to make sure you do the drywells in such a way that all the water is going to get in the drywells, like what you’re saying, instead of runoff to adjacent properties. However, this is a parking lot for your cars. There could be oil, gasoline, whatever else comes from cars. So that can all go in the drywell; and that’s all in the drywell very close to the ocean.So it’s not going to get the normal long-distance filtering as it works its way to the ocean that you would get on something more mauka. I know in past cases, not recently, but from a couple of years ago, there were some issues about some kind of filtering done on the drywell to be sure nothing got in there that didn’t belong. I’m also concerned that if a lot of water goes in the drywell here, how might it affect the flow of the other water going mauka-makai coming around. You know, I don’t have the right questions to ask. I just want to let you know about my concerns. And, you know, I don’t feel like I want to oppose the project because of this, but, you know, my sense is the homework has not been done adequately for me to feel like I can pass the buck. ALAMEDA:Okay. YUEN:Yeah. Well. Let me just make a couple of comments on that. I did see a study fairly recently that show that the amount of nutrients from parking lot runoff is quite low. There’s nearly nothing in parking lot runoff that causes nutrients.Oil is not soluble in water and, hence, does not tend to be carried with water. You’ll see when there’s a hard rain on an oily surface, you’ll see some water, some oil on the surface of that water, but it’s not typically carried with water the same way that a dissolved mineral like calcium would be carried with it. Finally, there are some things that if there are problems they are so much broader than the application that we have in front of us, that I’d hate to deal with it on the level of the application. Because if this is a problem, then the roads are all problems, the parking lots are all problems. Alii Drive is EXHIBIT C 6
