r---_ � Seahorse Restaurant W-5583 �` 18 March 1988 Page 5 Although preliminary site grades were not available at the time of this writing, -•• we anticipate that finished-grades will be obtained by minor cuts and fills with maximum cut and fill depths up to 5 feet. We understand from conversations with Mr. Cole, that soils from the higher portions of the existing ground surfacf. will be utilized to fill low spots t;o provide a somewhat level finished grade across the site. We recommend that initial site preparation include the demolition of the existing beach resort structures and the removal of debris from the site. All , i existing buried utilities should be removed or abandoned. Localized excavations �, for utility removal and removal of basements and foundations in the building or parking areas should be backfilled with "structural fill" as outlined subsequently. Utilities or buried fuel or septic tanks should be abandoned or backfilled in � accordance with State and local guidelines. All building and pavment areas, sidewalks and areas to receive "structural fill", should be stripped of all brush, vegetation, topsoil and other deleterious materials. Based on our test pit explorations, we estimate the stripping effort will typically encounter about 1/2 to 1 foot of topsoil and sod. Deeper areas of organics encountered in the portion of the site to he developed, such as tree root balls, should be anticipated and should also be removed and the excavations backfilled with structural fill as outlined subsequently. We also recommend that any fill materials such as encountered in the vicinity of test pit TP-4, be removed I and the metal, glass and deleterious construction materials be wasted offsite. Other isolated pockets of man-made uncontrolled fill and/or soft sedimentary localized deposits associated with Silver Lake may be present across the site. � The suitability of exposed native soils for foundation or floor support or for the placement or "structural fill" should be evaluated prior to structural fill placement. We recommend that areas to receive structural fill be prerolled and compacted prior to the placement of "structural fill". We recommend that prerolling be performed with a roller or other suitable heavy equipment to a firm and non- yielding condition in order to achieve a minimum c�mpaction level of at least 90 percent of the modified Proctor maximum dry density (as determined by
