I <br /> �iy�'y I <br /> H y The conclusion of the consultants was that the native soils � <br /> g �n within the development area are suitable for the proposed , <br /> �d y construction, and specific foundation recommendations were <br /> �� � presented. <br /> y o � d. Are there surface indications or history of unstable soils in <br /> " the immediate vicinity? If so, describe. <br /> None are known to either the applicant or contact person. <br /> Alderwood soils are not considered to be prone to instability, <br /> especially on slopes not exceeding 10 percent, a's with the <br /> subject property. <br /> e. Describe the purpose, type, and approximate quantities of any � <br /> filling or 9rading proposed. Indicate source of fill . <br /> Grading plans have been prepared For review, along with <br /> engineering and site development plans. Initial plans call for <br /> cut and fill on the site, with an estimated exportation of up <br /> � to 20,000 cubic yards of material . Due to the cost of exporta- <br /> i + tion, some changes to the plans may occur which utilizz all the <br /> �.�� excavated materials on site and result in no exportation. Where <br /> planned structures or roadways overly areas of deeper topsoil , <br /> previous woody fill areas or described wetlands, such locations <br /> I (�.� will be excavated and replaced with suitable structural fill <br /> �,1 excavated from other areas on the site. Excavated unsuitable , <br /> i material will either be retained on-site for use in landscapin9 <br /> i or will be removed from the site. ! <br /> i �.,�oO f. Could erosion occur as a result of clearing, construction, nr ! <br /> i .. <br /> use? If so, generally describe. <br /> Site filling and grading on any site will expose soils, thereby <br /> ���� creating a temporary increase in erosion potential . A temporary <br /> „ erosion and siltation control plan will be prepared and <br /> necessary controls will be installed prior to any grading <br /> ,� activity on the proposed project site, in accordance with City , <br /> ( � � of Everett requireinents. Depending on specific local site and <br /> "� " construction conditions, typical temporary measures employed <br /> during construction could include placement of straw bale <br /> barriers across drainage channels, placement of riprap and use <br /> ����� �7 of silt fences and siltation/detention ponds to control runoff. ' <br /> � Following construction, permanent erosion/sedimentation control , <br /> ,,, measures will include oil/grease separation and detenCion ponds , <br /> to reduce and remove particulates and li9hter-than-water <br /> fractions and biofiltration in a grass-lined swale in the south <br /> site margin. � <br /> I <br /> 5 I. <br /> , i <br /> I <br /> , I�' <br />
