Based on our review we provide this update to our previously prepared geotechnical letter/report. As implied, we understand thatthe project will now include a San Diego Regional Drawing Masonry Retaining Wall measuring less than six feet in retained height. As such, a geotechnical report is not generally considered necessary for the project. However, based on our review of the referenced plans, the plans are in accordance with appropriate geotechnical considerations for the site and have been signed and stamped by the undersigned for geotechnical purposes. In addition, from our geotechnical standpoint, the wall construction does not require structural inspection during construction; however, we recommend that CTE/UES review the wall foundation excavations to confirm appropriate conditions for concrete placement during construction. We appreciate the opportunity to be of service on this project. Should you have additional questions or comments, please do not hesitate to contact our office.

(CTE) has completed a geotechnical evaluap2n and is providing preliminary conclusions and recommendations for the proposed approximately~foot tall retaining wall at the above referenced site. Based on our evaluation, the proposed retaining wall will be suitable and stable for construction at the site, provided the design of the wall, by a qualified professional, utilizes the preliminary recommendations provided herein. 1.0 Site and Work Description The site consists of a previously graded building pad that supports an existing single-story, single- family residence. The previously graded building pad utilized an approximately 2: I (horizontal: vertical) slope to transition from the building pad to the street below. The proposed retaining wall will generally be used to replace the slope. 2.0 Laboratory Testing Laboratory tests were conducted on a selected soil samples for classification purposes, and to evaluate physical properties and engineering characteristics. Laboratory tests included: Modified Proctor and Remolded Direct Shear. The test results are attached herewith. 3.0 General CTE concludes that the proposed improvements on the site are feasible from a geotechnical standpoint, provided the preliminary recommendations in this report are incorporated into the design and construction of the project. Recommendations for the proposed earthwork and improvements are included in the following sections and Appendix D. However, recommendations in the text of this report supersede those presented in Appendix D should conflicts exist. These preliminary 1441 Montiel Road, Suite 115 I Escondido, CA92026 I Ph (760) 746-4955 I Fax (760) 746-9806 I www.cte-inc.net Proposed Noel Residence Retaining Wall 2715 Greenock Court Carlsbad, California January 31, 2020 Page 2 CTE Job No. 10-I5347G recommendations should either be confirmed as appropriate or updated following required excavations, demolition of existing improvements, and observations during site preparation. 3.1 Site Preparation Prior to grading, areas to receive distress sensitive improvements should be cleared of existing debris and deleterious materials. Objectionable materials, such as construction or demolition debris and vegetation not suitable for structural backfill should be properly disposed of off-site. We anticipate it will be suitable to excavate to the proposed wall foundation depths, wet down, and compact the surface of the exposed materials. As such, significant overexcavation is not anticipated. However, such conditions must be confirmed during construction. If loose or otherwise unsuitable materials are encountered at the base of overexcavations, additional excavation to the depth of suitable material may be necessary. A geotechnical representative from CTE should observe the exposed ground surface prior to placement of other compacted fill or improvements, to verify the competency of exposed subgrade materials. After approval by this office, the exposed subgrades, where or if they are to receive fill, should be scarified a minimum of eight inches, moisture conditioned, and properly compacted prior to fill placement. 3.2 Site Excavation Based on CTE's observations, shallow excavations at the site should generally be feasible using well-maintained heavy-duty construction equipment run by experienced operators. 3.3 Fill Placement and Compaction Areas to receive fills or backfill should be scarified approximately eight inches, moisture conditioned, and properly compacted. Fill and backfill should be compacted to a minimum relative compaction of 90 percent at above optimum moisture content, as evaluated by ASTM D I 557. The optimum lift thickness for fill soil depends on the type of compaction equipment used. Generally, backfill should be placed in uniform, horizontal lifts not exceeding eight inches in loose thickness. Fill placement and compaction should be conducted in conformance with local ordinances, and should be observed and tested by a CTE geotechnical representative. \\ESC_SERVER\Projects\l 0-15347G\Ltr_Ret Wall Recs.doc Proposed Noel Residence Retaining Wall 2715 Greenock Court Carlsbad, California Page 3 January 31 , 2020 CTE Job No. 1 0-l 5347G 3.4 Fill Materials Properly moisture conditioned very low to low expansion potential soils derived from the on-site materials are considered suitable for reuse on the site as compacted fill. If used, these materials should be screened of organics and materials generally greater than three inches in maximum dimension. Irreducible materials greater than three inches in maximum dimension should not be generally used in shallow fills (within three feet of proposed grades). Imported fill beneath structures and flatwork should have an Expansion Index of20 or less (ASTM D 4829). Imported fill soils for use in structural or slope areas should be evaluated by the soils engineer a minimum of two weeks before being imported to the site. 3.5 Temporary Construction Slopes The following recommended slopes should be relatively stable against deep-seated failure, but may experience localized sloughing. On-site soils are considered Type B soils with a recommended maximum slope ratio of 1: l. Actual field conditions and soil type designations must be verified by a "competent person" while excavations exist, according to Cal-OSHA regulations. In addition, the above sloping recommendations do not allow for surcharge loading at the top of slopes by vehicular traffic, equipment or materials. Appropriate surcharge setbacks must be maintained from the top of all unshared slopes. 3.6 Preliminary Retaining Wall Design Recommendations The following recommendations are for preliminary design purposes only. I. Allowable footing bearing pressure, at minimum depth of 12 inches below lowest adjacent subgrade elevation: 3,000 psf, plus an additional 250 psf for each additional six inches of embedment up to a maximum value of 3,500 psf. 2. Footings should have a minimum 7.5 feet distance to daylight from adjacent descending slopes. 3. Passive Soi I Pressure: 300 psf per foot of depth, with a maximum value of 3,000 psf. 4. Coefficient of Soil Friction: 0.30 5. Active and At-Rest (if needed) soil pressures should be as shown in Table 3.6. 6. If needed, a design seismic coefficient of 0.33 can be used for simple wall design. 7. The structural engineer should provide all footing and wall detailing and specifications. 8. A typical but adequate backdrain system should be installed for walls, as necessary and per the structural engineer or architect. \\ESC _ S ERVER\Projects\l 0-1534 7G\Ltr _ Ret Wall Recs.doc Proposed Noel Residence Retaining Wall 2715 Greenock Court Carlsbad, California January 31 , 2020 Page 4 CTE Job No. I 0-153470 TABLE3.6 EQUlV ALENT FLUlD UNIT WEIGHTS (Gh) (pounds per cubic foot) SLOPE BACKFILL WALL TYPE LEVEL BACKFILL 2: I (HORlZONTAL: VERTICAL) CANTlLEVER WALL 35 55 (YIELDING) RESTRArNED WALL 55 65 3.7 Seismic Design Criteria The seismic ground motion values listed in the table below were derived in accordance with the ASCE 7-16 Standard. This was accomplished by establishing the Site Class based on the soil properties at the site. Site coefficients and parameters were calculated using the U.S. Seismic Design Maps application. These values are intended for the design of structures to resist the effects of earthquake ground motions for the site coordinates 33.15960639° latitude and -117.30118606° longitude, as underlain by soils corresponding to site Class C. \\ESC_SERVER\Projects\10-15347G\Ltr_Ret Wall Recs.doc Proposed Noel Residence Retaining Wall 2715 Greenock Court Carlsbad, California January 31 , 2020 Page 5 CTE Job No. 10-15347G TABLE3.7 SEISMIC GROUND MOTION VALUES (CODE-BASED) 2019 CBC AND ASCE 7-16 PARAMETER VALUE 2019 CBC/ASCE 7-16 REFERENCE Site Class C ASCE 16, Chapter 20 Mapped Spectral Response 1.076 Figure 1613.2.1 (I) Acceleration Parameter, Ss Mapped Spectral Response 0.415 Figure 16 13.2.1 (2) Acceleration Parameter, S 1 Seismic Coefficient, Fa l Table 16 13.2.3 (l) Seismic Coefficient, Fv 1.385 Table 1613.2.3 (2) MCE Spectral Response 1.076 Section 1613.2.3 Acceleration Parameter, SMs MCE Spectral Response 0.575 Section I 6 I 3.2.3 Acceleration Parameter, SM1 Design Spectral Response 0.717 Section 1613.2.5(1) Acceleration, Parameter Sos Design Spectral Response 0.383 Section 1613.2.5 (2) Acceleration, Parameter Soi Peak Ground Acceleration 0.415 ASCE 16, Section 11.8.3 PGAM 3.8 Seismic Design The more detailed seismic design is required, the following can be used. Lateral pressures on cantilever retaining walls (yielding walls) over six feet high due to earthquake motions may be calculated based on work by Seed and Whitman ( 1970). The total lateral earth pressure against a properly drained and backfi lied cantilever retaining wall above the groundwater level can be expressed as: For non-yielding (or "restrained") walls, the total lateral earth pressure may be similarly calculated based on work by Wood (1973): Where P Alb = Static Active Earth Pressure = GhH2/2 \\ESC_SERVER\Projects\10-15347G\Ltr_Ret Wall Recs.doc Proposed Noel Residence Retaining Wall 2715 Greenock Court Carlsbad, California January 31, 2020 PK/b = Static Restrained Wall Earth Pressure = GhH2/2 ~p Ad b = Dynamic Active Earth Pressure Increment = (3/8) kh yH2 ~Pw b = Dynamic Restrained Earth Pressure Increment = kh yH2 b = unit length of wall (usually I foot) k11 = I /2* PGAm (PGAm given previously Table 6.8) Gh = Equivalent Fluid Unit Weight (given previously Table 6.9) H = Total Height of the retained soil y = Total Unit Weight of Soil ::::: 135 pounds per cubic foot Page 6 CTE Job No. I O-l 5347G *It is anticipated that the 1/2 reduction factor will be appropriate for proposed walls that are not substantially sensitive to movement during the design seismic event. Proposed walls that are more sensitive to such movement could utilize a 2/3 reduction factor. If any proposed walls require minimal to no movement during the design seismic event, no reduction factor to the peak ground acceleration should be used. The project structural engineer of record should determine the appropriate reduction factor to use (if any) based on the specific proposed wall characteristics. The static and increment of dynamic earth pressure in both cases may be applied with a line of action located at H/3 above the bottom of the wall (SEAOC, 2013). These values assume non-expansive backfill and free-draining conditions. Measures should be taken to prevent moisture buildup behind all retaining walls. Drainage measures should include free- draining backfill materials and sloped, perforated drains. These drains should discharge to an appropriate off-site location. Waterproofing should be as specified by the project architect. 3.9 Drainage Surface runoff should be collected and directed away from improvements by means of appropriate erosion-reducing devices and positive drainage should be established around the proposed improvements. Positive drainage should be directed away from improvements at a gradient of at least two percent for a distance of at least five feet. However, the project civil engineers should evaluate the on-site drainage and make necessary provisions to keep surface water from affecting the site. Generally, CTE recommends against allowing water to infiltrate building pads or adjacent to slopes. CTE understands that some agencies are encouraging the use of storm-water cleansing devices. Use of such devices tends to increase the possibility of adverse effects associated with high groundwater including slope instability. \\ESC_SERVER\Projects\10-15347G\Ltr_Ret Wall Recs.doc Proposed Noel Residence Retaining Wall 2715 Greenock Court Carlsbad, California January 31 , 2020 3.10 Slopes Page 7 CTE Job No. 10-15347G Based on anticipated soil strength characteristics slopes, if proposed, should be constructed at ratios of 2: I (horizontal: vertical) or flatter. These slope inclinations should exhibit factors of safety greater than 1.5. Although properly constructed slopes on this site should be grossly stable, the soils will be somewhat erodible. Therefore, runoff water should not be permitted to drain over the edges of slopes unless that water is confined to properly designed and constructed drainage facilities. Erosion-resistant vegetation should be maintained on the face of all slopes. Typically, soils along the top portion of a fill slope face will creep laterally. CTE recommends against building distress-sensitive hardscape improvements within five feet of slope crests, and against using thickened edges in this area.
