The buildings, Hayes, were actually built on solid ground whereas the athletic field was placed on top of what was once a pumice mine. There were actually a number of pumice mines at one time in the area, but I think this is the first time that they’ve tried to utilize the reclaimed property from one. The offer for the property was too good to pass up, and the future for that area looked enterprising. They gambled on the property and figured that “surely we won’t have a problem with an athletic field being placed on top of this stuff.” Pumice is like a bag of popcorn, and how popcorn doesn’t really mesh together. When the area got wet, all of the sand and fill material between the pumice basically washed downward thirty some feet to the solid rock. To excavate the area and replace with better material would be 9 to 12 million dollars. To do what’s called deep dynamic compaction where they drop a big heavy square weight would be 5.5 to 7 million, and vibro compaction would be 9 to 12 million – a higher tech way of compaction through vibration with water injection and sand infill. No matter how they look at it, the original price tag has skyrocketed. And what’s under your fields? Old cars and trucks? Graveyards? Oh yeah… lots of bad things that they may have covered up, eh?
