~ . have it in, I'd rather have it in - show it tonight - and then take it out later if it's not needed. To make it to the point where it's not needed, we'd have to fill in the pond to bring it up to an elevation where it would run off similar to a lawn. COUNCILMAN JOHNSON: What was the elevation of the road again? MR. MARCEL EIBENSTEINER: 962.5. COUNCILMAN JOHNSON: Center of the road or curb? MR. EIBENSTEINER: Center of the road. And the pond is 962.2. COUNCILMAN JOHNSON: You indicated that it is not what you consider a good design. What's the problem? MR. CHRISTOFFERSEN: I wasn't concentrating on what he said the road elevation was. COUNCILMAN JOHNSON: 962.5 against 962.2. The road is 3/l0 of a foot above . . MR. CHRISTOFFERSEN: What happens - first of all, he's basing it on the contour map. They could be off a foot or so. If this pond is lower than what shows on the contour map, even the way it is right now - you're talking two inches, three inches, four inches of water - the water would pond right up to the road surface and then flow over the boulevard 'area and into the road. That situation is not a good situation for drainage - to have open water filling into a large area and then spilling over into the road and running down the street to catch basins down below. If it was a grassy area - for instance, the pond could be filled up to a maximum level if you don't have an outflow. If you have a heavy storm, then all that water - you'd get lOO% runoff in that pond because it can't hold any more water, and it would just run right out into the street and down the street, where if ~t was lawn or turf there, you'd have an opportunity to run it off ahead of time. It wouldn't be ponding there and during the same type of heavy storm, you still wouldn't get lOO% runoff. . MR. GEORGE KRUEE, 4258 Norma Avenue: In the discussion about the road level, and earlier you mentioned the trees - where do the trees come in? If you allow natural runoff, the pond is going to fill up to a level at which it starts to run off. Where are the trees going to be involved in this? Are they going to be under high water then? MR. CHRISTOFFERSEN: I really don't have the exact elevations on the trees. (Inaudible) that we use for deter- mining these elevations are very preliminary in nature now and it was taken off the aerial contour map. There were not any surveys made to determine contours at this time. 7
