<br />, , <br />" <br /> <br />'~' <br /> <br />.' <br /> <br />. <br /> <br />.. <br /> <br />MR. CHRISTOFFERSEN: (Changed Tape) . . . four or five <br />acres of land draining at that point. The rule of thumb is one <br />cubic foot per second per acre. Another ~ule of thumb is two <br />cubic feet per second for the storm sewer. It appears to me <br />that at least half way up the road we would need some storm <br />sewer. At least up to this point right here, for some pick-up, <br />because we have approximately four c.f.s. - two c.f.s. (in- <br />audible). Obviously, for the purpose of the report, we put in <br />the storm sewer - the maximum amount that would be required <br />rather than the minimum amount. Obviously, if later on we find <br />out that we need more storm sewer and we didn't have it in the <br />hearing cost, we'd have to have another hearing. So we put the <br />cost in on top and work away from that if we can. It's my <br />opinion that storm sewers should go at least half way up, if <br />not three-quarters of the way up that hill, to pick up some of <br />that water draining down to the park. We can't solve the <br />drainage of that little low area of the park and recommend that <br />we (inaudible) right into that low area (inaudible) so it <br />doesn't overflow into the street. It's better to pick it up <br />a little bit at a time rather than all at once. <br /> <br />MAYOR WOODBURN: Don, would you reaffirm or clarify that <br />the pond level will not be changed, either way, whether the <br />water sheets down the road or whether it has been picked up <br />by storm drainage. <br /> <br />MR. CHRISTOFFERSEN: If the road grades could be set to <br />where they're below the pond level - I'm not sure whether it <br />would hold water for a great deal of time or not, I'm not that <br />familiar with it - but it shows up on the contour, map as a <br />low, isolated area that holds water, at least during a rain <br />storm. I don't know if it holds' it all the time or not. If <br />the water could be allowed to run across the curb without <br />ponding, then I think we need the storm sewer at least half to <br />three-quarters of the way up the road. However, if there is <br />a pond - if it does hold water - I would say we would be <br />working with the bottom of the current low level - to drain <br />that and keep it at a normal level. If there is water in' <br />there and it stands there the whole year round.- if it's <br />cat-tail, marshy land and the City wishes to keep it as such - <br />I would just recommend keeping it at its normal level, to <br />where it would remain as such. If it's a piece of land that <br />can be filled in and leaves the low level without disturbing <br />the trees or any heavy vegetation, I would say that could also <br />be done without appreciably damaging the property. Either <br />way, I think you could make it work. <br /> <br />MAYOR WOODBURN: So it can be developed without any <br />change in vegetation or trees, from what is presently there? <br /> <br />MR. CHRISTOFFERSEN: That's my feeling. I think it may <br />require a storm sewer to the park. <br /> <br />MAYOR WOODBURN: But it can be done and that's what we <br />wanted to clarify. To me, it's kind of unfortunate that this <br />has become - this feasibility study has become inexplicably <br /> <br />33 <br />
