12 1 Commissioner Rich: I don't know if this question is for you or for our staff. How come the 2 septic system is reviewed by the State as opposed to Orange County? 3 4 Chad Abbott: It is because the system at this site —and we designed these as well — I don't 5 know that we designed this system, but the system at this site, there was no conventional septic 6 field big enough for the uses on this site when it was built as a school. So therefore, they took 7 in the State—that is by Orange County deferred to the State, for design and approval by a 8 consultant and the State approves an Alternate Septic System, is what it's called. And it's an 9 alternate septic system. It's not your conventional septic tank with drain lines. It's a spray field. 10 11 Commissioner Rich: Follow up? So as you get more students in here, and you're building 12 more and more, it says that you're going to need to have additional septic field capacity? 13 14 Chad Abbott: Possibly, yes. 15 16 Commissioner Rich: Do you have room to have the additional capacity for the septic fields? 17 18 Chad Abbott: The way that would work would be an additional design. You know, the reason 19 for these alternative systems is that you don't have soil that perks, in the first place. And so 20 there's —you can look at the campus- there is abundant room to design an alternate system, 21 such that it can be—the discharge of those systems, or the spray, or the drip of those systems 22 is, is predicated by the infiltration rate of the soil. So whatever—there is abundant land, in 23 whichever section, if needed to add on to the existing system, you know would just be, the 24 design would be per that section of land. It's not a matter of it could be designed, it can be. It's 25 just whether or not— if it doesn't perk, you know it just requires a little bit more area, which 26 there's abundant area on the site. If one of the buildings shown creates a volume of waste 27 water that can't be treated on site, then obviously they'd just wouldn't be able to build that 28 building. 29 30 Commissioner Rich: And is that also regulated by the State, as you grow? So you would 31 have to get the State to approve that? 32 33 Chad Abbott: I think, I think, yes, I think the building permits with the County somehow through 34 this approval — I'm not going to speak for them —but would be tracked. The occupancy of each 35 building —which then, you know—the waste water flow is based on number of students. So as 36 those students grow, obviously it'll hit a trigger, for which the old septic system is now 37 insufficient, and would require a new design, or upgrade. 38 39 Patrick Mallet: I'll just add to that. So, this is the master planner conceptual part of the 40 process. So we're looking at things in what I would call a cartoon fashion. After that point, they 41 continue to refine, and there's not a necessary sequence in terms of the building, so they can't 42 really define their septic field. But, yes, when they would go and submit for any one of the 43 buildings, they would have to submit site plans for that building or buildings and then part of the 44 check off process would be to insure that there's enough capacity, and if not, they would have to 45 expand the field. The other thing that I would note is that the area that they are currently using 46 is — it's probably not even a third of the area south of Millhouse. They have a large 47 undeveloped, or underdeveloped, portion of property on the south side of Millhouse. 48 49 Commissioner Rich: Thank you. I mean I guess my biggest concern is that the State is 50 approving it, and I just want to make sure that we're also keeping track of it. I'm sure you all
