2.) Renohill-Buick-Lithe Association: Sloping to steep, loamy

soils that have a loamy to clayey subsoiI; moderately deep and deep

over shale or sandstone; on uplands.

This is the predominant soil a~sociation In the Big Ilry Creek

Basin and includes most of the central part of the study area. These

soils arc slowly to moderately permeable with a generally high swelling

potential. Runoff is moderate to rapid with slight to moderate erosion.

This soil association IS composed mainly of Reno!Jill Soils (loam 5"

surface layer;cl ay loam subsoil wi th ,;hale at 26" depths overlain "i th

lime deposits), Buick Soils (loam 6" surface layer \Vith a sanely clay

loam subsoil-lime at 12" depth), Lithe Soi ls (silty clay ]oan~ genera]]y

limy 3" surface layer, 13" layer clay or sil ty cl ['y subso:\l and cl ayey

sh:Jle at about 39" depth) and other llllnor soi 15,

3.) I-iunn-Bresser-Ascalon Associ atione;: deep, nearly level and

undulating; loamy soils that have a clayey to loamy subsoil; developed

In outwash; on uplands and terraces.

This soil association occurs In the area of South Broad"ay Avenue

within the Big Dry Creek Basin.

(jn level areas-about 3" loam surface layer; clay loam, 1 ight clay to

s:1nc1y clay loam subsoil to a 19" depth with lime at 23" depth-ponding

occurs where the subsoil is a dense c:l:,y), Bresser Soils, (on knobs

and roll ing areas-ilbout 5" sandy IO:lln "urfac:c layer, sandy lOilm to

sandy clay loam subsoil to obout 28" depth that lS vcry hard \\'ben dry);

Ascalon Soils (similar to Bresser Soil" abuve l1ith a grilyer subsoil and

lime at about 17" depth) and other minor sojls.
