INTRODUCTION COUNTY OF ORANGE OC PUBLlC WORKS I OC PLANNING PERMIT# REPORTS APPROVED )q unconditionally 0 Conditionally DATE: 5--23~Vc> ( !'- Wall Construction 1§. r/~ ~ Engineering GeokiQJSt 0 Civil Engineer a) This letter provides our geotechnical evaluation for the proposed pool/spa and retaining wall construction to be located in Newport Coast, County of Orange, California. No subsurface exploration was copducted during the course of preparing this report. we assume the stability. of the nearby slopes has been assessed and approved in conjunction with the development of the tract. b) As we understand, the planned improvements will include the construction of a new swimming pool within the rear (western) area of the lot. The depth of the pool will range from 3.5 to 5.5 feet. In a addition a new 5-foot high retaining wall is planned along a part of the north-lying ascending slope. The project scope will also include new hardscape and flatwork areas. The recommendations provided in this report are for the swimming pool/spa and retaining wall only. If requested, we will provide additional recommendations for the other improvements. c) Evaluation of the existing residence and other structures was beyond the scope of our services. The subgrade soils below the pool and the spa were not investigated and therefore the quality of the soils is not known. It is possible that the sub grade soils may impact the performance of the pool/spa. 3 Corporate Park, Suite 270, Irvine, California 92606 Office (949) 221-0900 Fax (949) 221-0091 e-mail: global@globaigeo.net Geoscape March 18,2014 Project 5800-81 Page 2 2. SITE CONDITIONS a) During the course of preparing this report, we have conducted a site reconnaissance of· the property, specifically in the vicinity of the proposed improvements. b) The subject parcel is developed with a two-story, wood-frame, single family residence on a relatively level pad. A rectangular shaped, 18-inch deep, concrete lined pond is present within the center part of the rear area of the lot. The pond is surrounded by concrete tile flatwork. The remainder of the rear yard area is covered by grass· and planters. c) Along the northern side of the property, a 4-foot high (3 feet retaining) concrete wall extends along the bottom of a 2-to 3-foot high slope which ascends up to the bottom of a 6.5-foot high free-standing concrete block property line wall. d) A 6-to 8-inch high concrete curb exists along the rear edge of the yard area. Beyond the curb is an -8~f()ot high, 2: l; (horizontal:vertical) slope which descends to the west-lying wrought iron property line fence. Beyond the fence <is~a:44~fci()t ~ high slope descending at a gradient 2:1 (horizontal:vertical). The slope is very well vegetated and appears to be well maintained. A 5-foot wide concrete terrace drain extends midway through the slope. d) With respect to the existing yard improvements, the concrete pond and flatwork appear to be generally in good condition and are free of any obvious distress. 3. COUNTY POLICY In late 2005 and early 2006, the County of Orange implemented a general policy relating to Expansion Index testing as they related to swimming pool and hardscape/flatwork · construction and has been generally accepted by the geotechnical and construction community since that time. The general nature of the policy suggested that, in the absence of any site-specific EJ or Soluble Sulphate testing and analysis, the geotechnical design recommendation must assume very high EI and Severe sulphate exposure. It is our professional opinion that, this policy is ·generally sound and should continue as unchanged as it is considered the most conservative for the varying soil conditions. 4. POOL AND SPA CONSTRUCTION a) From a geotechnical point of view, the proposed pool and spa construction is considered feasible, provided the reconlinendations are implemented during the design and the construction phase. -Geoscape March 18,2014 Project 5800-81 Page 3 b) A portion of the pool within 25 feet from the top of the slope should be designed · for structurally free-standing conditions. For the design of the pool, use an allowable bearing capacity of 1,500 lb/ft2 at 1-foot depth in accordance with the 2013 California Building Code. Use an equivalent fluid pressure of 100 lb/ft3 for the walls of the pool, supporting an expansive, level backfill. c) The sub grade soils may have sulphate contents greater than 0.2 percent. The sulphate exposure is considered Severe. The project structural engineer should be notified about the high sulphate content. d) For the shotcrete/concrete construction, the compressive strength should be 4,500 lb/in2 and water/cement ratio of 0.45 should be used, in addition to using Type V cement. e) A representative sample of the sub grade soils may be collected and tested to determine the sulphate exposure at the conclusion of the excavation. If the sulphate content is less than 0.1 percent, the compressive strength of the shotcrete/concrete may be reduced. f) Based upon the pool plans, we understand that the western (slope-side) edge of the spa excavation, will be located between 3 feet horizontally away from the top of the descending slope, whereas the eastern edge of the pool will be located 1 0 feet from the top of the slope. g) i) One of the goals of conducting a pre-excavation, geotechnical evaluation report is to identify potential geologic hazards or subsurface soil conditions which may be a detrimental to the planned improvements. The evaluation is partially based upon observation of existing site conditions, and our experience with similar types of construction within the general proximity of the site. ii) Detailed analysis of the existing slope stability was beyond the scope of our work. However, structures and hardscape improvements located near the top of descending slopes will often undergo a process of slope creep or lateral fill extension (lot stretching). Slope creep is defined as, very slow, nearly imperceptible rates of downslope movement, occurring from alternating wetting and drying of the fill soils, typically along the outer 5 to 20 feet of the slope surface. iii) Many factors are involved in the magnitude of slope creep effects. They include; • The overall slope height; • The quality of the fill compaction; • Type of fill soils; • Amount of surface irrigation, and surface and subsurface drainage. Geoscape March 18, 2014 Project 5800-81 Page4 h) iv) With respect to the water infiltration into the surface soils, exposed along the creep-prone slopes, the degree of water infiltration and subsequent creep effects may be controlled by surface drainage, runoff, and slope maintenance .. v) vi) i) Because slope creep and lateral fill extension will likely remain active throughout the life of the structure, we strongly recommend that for the pool, construction, a deepened keyway be incorporated into the design and construction. The deepened keyway should be included along the eastern (slope-side) edge of the excavation: deepened such that the horizontal setback from the bottom of the ke~ay: is measured 20 feet.fr-9rn.tb.~..fac_e_ofJhe descending slope. The keyway should have a.minimum width of 18 inches. We estimate the depth of the keyway will be approximately ITfeetalong the spa and the shallow portion ofthe pool, tapering to o:he foot·in the pool's deep end. For the keyway design, use an active pressure of 45 lb/fe, a passive resistance of250 lb/ft3and a coefficient of friction of0.3. It is critical for the performance of the pool that the underlying subsurface materials exposed in the bottom of the excavation be of similar material type (either bedrock or fill) and be consistent in thickness, and be sufficiently dense to support the gunite shell without the risk of settlement. ii) We anticipate that the pool excavation Will expose fill. No overexcavation is deemed necessary, provided that the exposed subgrade is deemed suitable. iii) However, if a bedrock/fill transition or unsuitable soils are encountered, we recommend that the entire swimming pool be overexcavated to a minimum depth of 1.5 feet, subject to review during the excavation process. The resulting excavation should be backfilled with engineered fill, compacted to 90 percent relative compaction. Onsite soils generated during the overexcavation process may not be suitable for re-use as compacted fill due to its anticipated excessive moisture content, subject to review during the excavation process. As an alternative to a compacted soil backfill, the backfill material may consist of %-inch crushed rock or. gravel. Pea gravel backfill is :hot specifically recommended. i) If any signs of groundwater seepage occur, then installation of a hydrostatic relief valve may be necessary. Determination of a hydrostatic valve will be made· following the excavation of the pool. j) At this time, we do not believe that the excavation will require shoring, subject to review during the excavation process. Geoscape March 18, 2014 Project 5800-81 Page 5 k) The pool excavation will be observed by a geotechnical engineer or an engineering geologist. Any adverse conditions exposed during the excavation Will be evaluated by us and mitigating recommendations, if required, will be provided with due consideration given to the exposed geologic conditions including bedding, height of the excavation etc. If the excavation of the pool is planned during winter months, it should insured that exposed temporary cuts for the excavation are covered sufficiently with plastic and secured with sand bags to prevent surficial erosion and possible failure. 1) In general, due to the presence of the highly expansive underlying soils, the planned hardscape and flatwork will be highly susceptible to soil expansion effects such as cracking and heaving. Hardscape areas planned for this project should be designed in order to counteract the effects of the highly expansive soil conditions, slope creep and Lateral Fill Extension. Implementation of mitigating measures, can limit the amount of expansive soil affects on hardscape. m) The recommendations included in this report are intended to minimize the potential of distress caused by the underlying soils. However, it should be noted ·that certain amount of cracking, uplifting and tilting of may be unavoidable and should be anticipated during the lifetime of the proposed structures. 5. RETAINING WALL CONSTRUCTION 5.1 General a) It is our opinion that the site will be suitable for the proposed decks and retaining wall improvements, assuming that our recommendations are implemented during construction. b) We are of the opinion that the proposed footings may be supported on the new footings founded in the competent soils. c) We are also of the opinion that with due and reasonable precautions, the proposed construction will not endanger adjacent property nor will construction be affected adversely by adjoining property. d) The earthwork operations should be observed by a representative of a geotechnical engineer. e) The design recommendations in the report should be reviewed during the grading phase when soil conditions in the excavations become expos~. 5.2 Processing of On-Site Soils a) At this time, no overexcavation is required below the bottom of the footings, provided the footings are founded in the competent fill soils. Geoscape. March 18, 2014 Project 5800-81 Page 6 b) If any slab-on-grade is constructed, the existing disturbed sub grade soils should be' reworked for a depth of 8 to 10 inches. c) Wherever structural fills, if any, are to be placed, the upper 6 to 8 inches of the exposed sub grade should be scarified and reworked. d) Any loosening of reworked or native material, consequent to the passage of construction traffic, weathering, etc., should be made good prior to further construction. e) The depths of overexcavation, if any, should be reviewed by the Geotechnical Engineer during construction. Any surface or subsurface obstructions, or any variation of site materials or conditions encountered during grading should be brought immediately to the attention of the Geotechnical Engineer for proper exposure, removal or processing, as directed. f) No underground obstructions or facilities should remain in any structural areas. Depressions and/or cavities created as a result of the removal of obstructions should be backfilled properly with suitable materials, and compacted. 5.3 Material Selection (for any new fills) After the site has been stripped of any debris, excavated on-site soils are considered satisfactory for reuse in the construction of on-site fills. Concrete pieces greater than 4 inches in diameter should not be incorporated in compacted fill below slab-on-grade. 5.4 Compaction Requirements a) Reworking/compaction shall include moisture-conditioning/drying as needed to bring the soils to slightly above the optimum moisture content. All reworked soils and structural fills should be densified to achieve at least 90 percent relative compaction with reference to laboratory compaction standard. b) The optimum moisture content and maximum dry density should be determined in the laboratory in accordance with ASTM Test Designation D1557. c) Fill should be compacted in lifts not exceeding 8 inches (loose). 5.5 . Excavating Conditions a) Excavation of on-site materials may be accomplished with standard earthmoving or trenching equipment. Geoscape March 18,2014 Project 5800-81 Page 7 b) Dewatering is not anticipated. c) Portions· of the demolished structures, if any, should be removed entirely from within the structural areas. Care should be taken not to undermine the foundations to be left in place. 5.6 Expansivity Based on our observations, the expansion potential of the underlying material is considered to be medium. The slab (if any) and the footings should be designed in accordance with California Building Code. A subgrade soil sample should be collected and tested to determine the expansion potential. 5.7 Sulphate Content The subgrade soils may have sulphate contents greater than 0.2 percent. The sulphate exposure is considered Severe. The project structural engineer should be notified about the high sulphate content. 5.8 Grading Control All grading and earthwork should be performed under the observation of a Geotechnical Engineer in order to achieve proper subgrade preparation, selection of satisfactory materials, placement and compaction of all structural fill. Sufficient notification prior to stripping and earthwork construction is essential to make certain that the work will be adequately observed and tested. 5.9 Surface Drainage In accordance with the building code, the ground adjacent to the foundation should be sloped away at gradient of 5 percent. If the ground adjacent to the residence is covered with impervious material, the area adjacent to the foundations may be sloped away at 2 percent gradient. 5.10 Slab-on-Grade (if any) The recommendations provided here assume that the subgrade soils have medium expansion potential. The soils should be tested to verify the expansion potential. a) · Concrete floor slabs may be founded on the reworked existing soils or compacted fill. b) The sub grade should be proof-rolled just prior to construction to provide a firm, unyielding surface. Geoscape. March 18,2014 Pr9ject 5800-81 Page 8 c) The slab-on-grade should be underlain by 4-inch thick SAND. A plastic vapor barrier ·is recommended. This sheeting should be placed at the midheight of the SAND. d) It is recommended that #4 bars on 16-inch center, bothways, or equivalent be provided as minimum reinforcement in slabs-on-grade. Joints should be provided and slabs· should be at least 4 inches thick. e) The FFL should be at least 6 inches above highest adjacent grade. f) The subgrade should be kept moist prior to the concrete pour. 5.11 Spread Foundations a) The proposed structures can be founded on shallow spread footings. The minimum criteria are· presented below. However, the design footing dimensions significantly exceed the minimum criteria. b) Dimensions/Embedment Depths Minimum Width Minimum Embedment Below Lowest Finished Surface Square Column Footings to 50 kip c) Allowable Bearing Capacity (Notes: Embedment Depth (ft) 1.5 I I (ft) - (ft) 1.5 Allowable Bearing Capacity (lb/ft2) 1,650 • The allowable bearing capacity may be increased by 20 percent for each additional foot increase in the depth or the width, to a maximum value of 3,500 lb/ft2; • These values may be increased by one-third in the case of short-duration loads, such as induced by wind or seismic forces; & Planter areas should not be sited adjacent to walls. In case planter areas are sited next to the walls the footings should be deepened by additional six inches; Geoscape , ~l March 18,2014 Project 5800-81 Page 9 • Footings adjacent to the slope should be sited such that horizontal distance from the lower outer edge of the footings to the competent slope shouldbe 113rct x the slope height; minimum 6 feet and need not exceed 40 feet; • Footing excavations should be observed by the Geotechnical Engineer to verify the footings are excavated in the competent soils and are in one type of soils; • Footing excavations should be kept moist prior to the concrete pour; • It should be insured that the embedment depths do not become reduced or adversely affected by erosion, softening, planting, digging, etc.) 5 .12 Lateral Pressures a) The following lateral pressures are recommended for the design of retaining structures. Pressure (lb/felft depth) Lateral Force Soil Profile Rigidly Supported Unrestrained Wall Wall Active Pressure Level 60 - Passive Resistance Level 250 - (igriore upper 1.5 ft.) - b) Friction coefficient: 0.3 (includes a Factor of Safety of 1.5). While combining friction with passive resistance, reduce passive by 113. c) These values apply to the existing soil, and to compacted backfill generated from in-situ material. Imported material should be evaluated separately. d) It is recommended that where feasible, imported granular backfill be utilized, for a width equal to approximately one-quarter the wall height, and not less than 1.5 feet. e) Backfill should be placed under engineering control. f) Subdrains comprised of 4-inch perforated (holes facing downwards) Schedule 40 or equivalent PVC pipe covered in a minimum of one cubic foot per linear foot of filter rock and wrapped in Mirafi 140N filter fabric should be provided behind retaining walls.
