<br />BUILDING SITE DEVELOPMENT
<br />Endnote -- BUILDING SITE DEVELOPMENT
<br />This report shows the degree and kind of soil limitaCions ChaC affecC shallow excavations, dwellings with and without
<br />basements, small commercial buildings, local roads and streeCa, and lawns and landaca~ing. The limitations are
<br />r
<br />"S11ghC", "Moderate", or "Severe". The limit~tlons are considered "S11ghC" if soil properties and site features are
<br />generally favorable Por the indicated use and limitaion9 are minor and easily overcome; "Moderate" if Boil properties
<br />or site features are not favorable for the ine}iCated use and special planning, design, or mainCenance is needed Co
<br />overcome or minimize the limitations; and "Severe" if soil properties or site Features are eo unfavorable or eo
<br />difficult to overcome that apetial design, significant increases in construction costs, and possibly increased
<br />maintenance are required. Special feasibility studies may be required where Che soil limitations are severe.
<br />SHALLOW EXCAVATIONS are Crenchee or holes dug to a maximum depth of 5 or 6 feet for basements, graves, utility lines,
<br />open ditches, and other purposes. The ratings are based on sail propertiea,,site featiurea, and observed performance of
<br />Che soils. The ease o! digging, tilling, apd compacting is affected by the depth to bedrock, a cemeaCed pan, or a very
<br />firm dense Layer; atone coriCent; soil texture; and elope. The Clme of the year that excavations can be made ie
<br />affeoCed by the depth to a aeaeonal high water table and the auseepEibility of the soil to flooding. The resisCarice e!
<br />the excavatiori walla ar bAnds,to sloughing or saving is affected by soil Cexture and Cho depth t0 Che wafer Cable.
<br />DWELLINGS AND SMALL COI~M~lERCIAL HUILDINGB are aCXUCturea bu11C on shallow foundaCiona on undisCurbed sail- The load
<br />limiC is the same as r-hat for aiagle-family dwellings no higher than three stories. RaCixs3e are made !or small
<br />commercial buildings withouC basements, fox dwellings with baaemenCS, and for dwellings without basements. The ratings
<br />are based on soil properties, siCe feaCuree, and observed performance of Che soils. A high wafer Cable,. depth to bedrock
<br />or Ca a cemented pan, large stones, slope, and flooding affect the ease of excavaCioa and conaCruction. Landacapirig
<br />and grading Chat require cuts and fills of more Chan 5 or 6 feeC are rioC considered.
<br />LOCAL. RAADS AND STREETS have an all-weather surface and carry automobile and lighC truck traffic all year. They
<br />have a aubgrade of cut or till soil material, a base of gravel, crushed rock, or sCabilized evil mACerial, and a
<br />Elcxible os rigid surface. Cuts and !ills are generally properties, siCe features, and observed performance of the
<br />soils. Depth to bedrock ar Co a cemented pan, a high wafer table, flooding, large stones, and slope affect the ease of
<br />excavaCing and grading. Soil strength (ae inferred from Che engineering classification of Che soil), shrink-swell
<br />potential, frost action potential, and depth Co a high wafer table affect the traffic-supporting capacity.
<br />LAWNS AND LANDSCAPINC3 require soils on which Curf and arnamenCal frees and shrubs can be established and
<br />maintained. The ratings are based oa soil properties, site features, and observed perlormarice o! Che soils. Soil
<br />reaction, a high wafer Cable.: depth ee bedrock nr Cn a cemented pan, Che available wafer capacity in the upper as
<br />inchea,'and Che coriterit of ss~CSy sadl.um, and sullidic maCerialo affecC p1anC growth. Flooding, wetness, slope,
<br />stoniness, and Che amouaC of sand, clAy. or organic matCer is the surface layer alfeet Craflicability after vegetation
<br />is established.
