THE NEW AMERICA'S TEAM
That wall is like 3 to 4 feet but the hill side is about 2 ft. Remember that every area and regions are different, the diagram would be correct if the earth was flat and all ground are equal. It's not thats why you have geos on every project. All earth react different. The field was actually raised with a soul Cement base. So now the fans will be closer to the game play and the field will drain into the new drainage system installed around the stadium. Now what I question is how the hell they get the water up the hill. I have never seen a pump but then again I have never ventured into the room sitting next to the down ramp. Im would think it's electrical but it could be a outdated pump thats being replaced.
Two things, if you zoom in on Founder's image below, the wall is approximately 1 to 1.5-ft. higher than the top step/landing of the stadium steps in the right corner. There are 6 steps total. A standard step is approximately 8-inches high. 6 X 8 = 48-inches or 4-ft. Therefore, the top step is approximately 4-ft. high from ground level. If you add 1 to 1.5-ft to 4-ft., the wall would be approximately 5 to 5.5-ft. Also, unless it's an optical illusion, the construction crew behind the goal post must be an all midget crew.
And for your pump question, a lot of pumps are submersible pumps, which means they would be placed in some wet-well below ground elevation. Therefore, you would not be able to see the pumps unless you remove some manhole cover and look down into the wet-well. Due to limited space, I've actually designed a set of submersible pumps placed in the middle of a road in Kenner, LA. The last image below show two manhole covers at street level for the wet-well of the submersible pumps and the value box that I designed, with a little white Toyota parked on top of them. The only thing a person would see are the LOCKED manhole covers at street level. Now the brick building to the right in Founder's picture could quite possibly be the pump house. The four vent hoods on top of the building could be ventilation for four pumps. If that is the case, I assume the pump control panel is program to equally alternate the operation time of each pump, so that one pump doesn't get overworked. Also, multiple pumps can operate at the same time in case one or two pumps can't keep up or can't discharge enough water fast enough.
