FML, Inc. STS Project 93589 August g st 28, 1985 RECOMMEDATIONS i GENERAL ' Based on the Site Planprovided by Pope Associates, P ociates, Inc. it appears that most of the proposed townhomes will be located on the ' half of the site, in the area of natural soils. eastern plexes are to be located near the north end of Two of the four - Because the earthwork and site the fill area. j� preparations for foundation con- struction, utility placement and bituminous �1 pavement design are considerably different for the filled and natural soil areas, specific recommendations for site preparation will be addressed separately for these two areas. NATURAL SOIL AREAS 1.1 1. Earthwork We reco mmend that any surficial topsoil and/or the organic root mat be stripped from the building and pavement development f ar estimate treat this w' eas. We ill require stripping to a depth of approxi- mately 6 inches over most of the area. Existing trees and bus should be cleared and rubbed bushes 9 to remove system. We recommend that P11 strippingo e the majority of the root �] an experienced S:'a Engineer or operations be observed by Technician to observe the organic root mat and determine the suitabilitythe removal of j soils for placement of fill or foundations. °f underlying Borings within the natural soil area indicate that the w surf � soils are relatively loose ica.al Y se as determined by Standard Penetration testing. These loose soils extend to a depth of approximately � PP ately 1.5 to 4 ft below the ground surface at the boring locations. The low Standard Penetration blow counts encountered in these surfici soils indicate that in their a1 present condition these materials are not suitable for support of building foundations. We recommend that building foundations be based at a depth below this zo ne of
