on top. You have the same distribution of piping that blows the air through a base of actually stone and above that is 3-4 feet of mulch material and then 6-9 inches of topsoil, and thus the short, shallow rooted plants. Same concept though, it essentially goes through the 3-5 year timeframe. Sassano: So what's visible is top soil? Carnahan: Correct. Top soil and whatever annuals they use. You have to realize that every 3-5 years it will have to be replaced. Sassano: But it's not like what you see is all going to turn black... because that's all. happening below... ? Carnahan: Correct. That layer is... Sassano: So you don't have kids running around and playing on top of stuff that's been collecting all of this.... Carnahan: No, it's all below. Littrell: This is a busy part of the park. People come by to watch tennis and sliding in the winter, so... Sassano: Is there just like a man hole... is there any kind of access to it? Carnahan: No. A pipe will come underground to it so it will be down 4-5 below, come across the road and underneath. It's like a buried pit irrigation system, it will be deeper than that, but you can think of it that way. Sassano: So the average person would have no idea what's underneath there? Carnahan: No, that's the beauty of it. Littrell: And the air is gently forced through there, it's not blown as though you're depending on the weight of things to hold it down. Klusczinski: The Chair recognizes Commissioner Riley. Riley: Two questions- ifyou're just blowing air gently through there, there shouldn't be any breakdowns of equipment or problems that you'd have to tear it up to repair it. Carnahan: No, there aren't- you won't have any moving parts or the need for access to the piping. The access would be up here, and as Carl said this is all being removed and you'd have a blower on to, essentially similar to what's there so any maintenance or access would be on top of the structure. Riley: Well that was my next question, the two pictures underneath that, will all of that equipment be visible or begone? Carnahan: All of that will be gone; however there will still be a blower on top to pull the air off. On top of the piping because it all collects in this structure. So you would, these tanks, all this piping would be removed, and this blower would be replaced with a different blower. Riley: So it would just be a small unit.... Carnahan: Depends on your definition of small. Klusczinski: Is it a quiet unit? Carnahan: It's similar to the sound that's coming off of here now, it's not a high pressure blower. It's more like a fan. I went by it today, and it's really not much different than what's there now. Klusczinski:.[ had an additional question and I don't know if this is for Pat or Carl, but the graph paper sketch shows tree plantings but I don't see any evidence of those in the garden illustration. Do you intend to put trees there, or...? Littrell: That's the existing trees; we're keeping the flower bed out from the drip so that we don't have root intrusion from those trees. Chase: So presently it's been exhausted through the structure in those pictures? Carnahan: Correct, it's being pushed through here and they're using an active chemical reaction as opposed to a biological reaction. Chase: Putting the new sewer system is that going to help or not change anything with the odors. Littrell: It potentially has the possibility of making it worse. We're taking storm water little by little out of the system which tends to dilute it. 4
