Water collected in�o 1he underground drain line systems should be tigt►Uined to <br /> discharge into a nearby storm sewer. <br /> BUILDING SETBACK <br /> The purpose of building setback from the top or toe or an overly steep portion of a slope is to <br /> establish a safe buffcr such that if a slopc failure should occur ihe stability of the shvcture can be <br /> maintained and damagcs to the structure minimized. To maintain its stability, the new house to <br /> be wnstructed on the sitc should be sufficiently setback from the crest of slope 40% or stceper. <br /> If the nbove recommendations for site stabilization are fully implemented and observed during <br /> conshvction, it is our recommendation that the house may be set back at least 15 feet from the <br /> top of steep slope bordering thc west side of the site. Als��, the fr,ut�ng foundations of the house <br /> should be embedded at least 12 inches into the undedying,very-dense, fresh lill soils. <br /> CLOSURE <br /> We are pleased to be of servicc to you on this project.
