3.0 FINDINGS
3.1 Site History and Current Use
The grounds for the Everton Electronic Scoring Site were historically used for growing corn, but
the productivity of the land was quickly reduced. When the land was acquired by Denton Yearns
in 1963 it became grazing pasture for cattle (USAF 1993b). The leased property is now used for
the Electronic Scoring Site. On June 18, 1996 this property was placed under the civilian control
of Lockheed Martin who employs 25 to 30 personnel (Brumett 1998, Sumey 1998). The land use
at the Mini-MUTE sites has historically been agricultural land for grazing, which continues on
most of the adjoining properties. All the sites were rural and surrounded by either productive or
nonproductive agricultural land.
3.2 Environmental Setting
The Everton Electronic Scoring Site is located in an area used primarily for agriculture. The
facility has a gravel parking lot and drive from State Highway 206. Areas of maintained lawn are
present to the south, east, and west. Lawn species include red fescue (Festuca rubra) and
Bermuda grass (Cynodon dactylon). The site contains several species of trees (Quercus falcata
and Ulmus alata) and a few of the larger trees create shade for the employee break area, south of
the facility (USAF 1993a). An unused Mini-MUTE radar unit sits in the lawn, south of the
facility. The topography of the site was relatively flat and the site elevation was 1,120 feet above
ground level (AGL) (USGS 1975). The dominant soil type found at the Everton Electronic
Scoring Site is Noark very cherty silt loam with 3 to 8 percent slopes. This soil, formed from
residuum from cherty limestone, is deep, well drained, and moderately permeable (USDA 1981).
The building is heated and cooled electrically, with power supplied by Arkansas Power and
Lighting. Fire protection is provided by the City of Valley Springs and police protection is
provided by Boone County (Brumett 1998, Sumey 1998, Record 1998).
The Mini-MUTE sites have variable environmental settings. Mini-MUTE site 4MM1 is situated
in an area surrounded by grazing land. The vegetation present at the site is primarily native
grasses and weedy species. The topography is relatively flat and a small drainage swale is
located in the northeast section of the property. The site elevation is approximately 1,200 feet
AGL (USGS 1966). Some backfilling has been performed to create a level surface for the radar
pad. The fill is grated from the surrounding area and no outside material used (Dillard 1998).
The dominant soil type found at the site is Sidon silt loam wit 3 to 8 percent slopes. This soil is
