Waste management in the Omaha metropolitan area:

Landfills in the Omaha area:

Heflinger Park in Omaha is a good example of an old landfill that was on the periphery of the city, but has now been encircled by growth of the city westward. The old trenches that the garbage was put in continue to subside, and the road and parking lot show cracks associated with the differential compaction. The road has been repaired many times. On the south side of the landfill, next to a housing development are some methane venting pipes, and drainage control. Heron Haven, a partially restored wetland, is just across the road to the NW.

The above image is a 1999 USGS airphoto of Heflinger Park downloaded from the Terraserver website. North is to the top. One can see the four baseball diamonds, which are centered on the park, and the light colored parking lot to the east. One can also see the neighborhood to the south, which lies at a lower elevation than the landfill. The northern edge of the neighborhood is the southern margin of the landfill. Note the stream on the north side. Perhaps most notable is how relatively inconspicuous this old landfill is.

Douglas County Landfill

1999 USGS airphoto of Douglas County landfill NW of Bennington. The east-west road toward the bottom is Route 36. Note that the landfill is located on top of a drainage divide so that the streams on one side flow into the Elkhorn and the ones on the other into the Missouri. The beginning of the hill that marks the landfill is evident. The landfill has grown considerably since this was taken. Note that the section roads (1 mile segments) allow you to have an idea of scale. The surrounding area is mainly used for agricultural purposes. The geologic substrate here is loess.

Old landfill near Mormon Bridge.

This is a 1999 USGS air photo of an old landfill that can be seen when driving into Iowa across the Mormon Bridge. In the center of the photo you can note an area that is different than the surrounding flood plain. It is covered with a different type of vegetation and is not used for agriculture. You can also note how the diffuse stripes that reflect the position of old channel margins are truncated (covered) by this landfill area. If you drive by it is an area that is noticeably above the rest of the flood plain. Here, they could not dig much below the surface because they would have encountered the groundwater table at a shallow level. So instead they built above the landfill surface. I know little else about this landfill. Natural questions to ask include the following. When did it operate? Does it have liners? Is the site being monitored? Why did they chose this site?

Sarpy County Landfill

The above image is a USGS airphoto from 1999 of the Sarpy County Landfill, that is just west of Route 50, near Springfield. The distance between the roads is a section, or one mile. As might be expected, this landfill is smaller than the Douglas County one. North is towards the top. Again the surrounding area is used for agriculture. An excavation pit and a mound of garbage or both evident. The geologic substrate here is loess.
