Flooding occurs along the stream banks of the South Fork of Muck Creek, which bisects the Northern portion of our property. This area consists of our Wetland Mitigation area and was specifically designed to incorporate the floodwaters. In fact, LRI lowered the elevation in several areas to increase flood storage on-site with the intent to help the flooding that occurs off-site down stream.

Secondly, the flooding that occurs on-site originates from two causes, one is in coming water from north of 304th St. and the other is due to a culvert that is undersized under SR 161 (Meridian). The undersized culvert acts like a dam until such time enough water is held on-site to overtop the roadway. The elevation of Meridian is 632.0 and the elevation of our service road is 655.0. Therefore, Meridian would have to have 23 feet of standing water on it before the stormwaters would be at such a height to breech our service road that surrounds our landfill. The FEMA registered 100 and 500 year flood elevations of this area allows a total of 2.6 feet at it's highest elevation to stand on Meridian. That is substantially different from the 23 feet needed to flood the landfill.

Finally, is the fact that water stands on this site due to the low permeability of the soils. The water is held on the surface which creates wetlands and an optimal landfill location. The soils are so tight they don't perk which in turn is a great natural protective barrier for the uppermost aquifer 45-50 feet below grade. So, in addition to the state-of-the-art engineered liner system this landfill is sited on a natural protective layer of at least 45 feet.
