Note that the scope of services authorized and provided herein is Umited to a sfi-uctural design of the proposed Verdura Retaining Wall system. SRD did not provide any on-site geoteclmical services such as subsurface investigations or identification/testing of soil materials that may be used in or near the proposed Verdura 40 Retaining wall. Information presented herein is based on data provided in the reference documents. If the conditions differ from those presented in the referenced documents, the engineering design and analyses provided by SRD may no longer be valid and additional engineering and analysis services may be required. Conditions noted above include, but are not limited to slope configurations, wall system type, wall/slope heights, soil materials and structure loadings. In addition, it should be noted that SRD is the wall designer and not the geotechnical engineer-of-record. VERDURA 40 RETAINING WALL General - The site consists of a various proposed Verdura retaining walls and configurations (Walls A through G) that are located throughout the site. The proposed walls A and B are in a double terrace configuration and run along the southwestem portion of the site adjacent to Black Skimmer Drive and Dove Lane. These walls support a proposed ascending 2:1 slope that extends up to the building pad area, and a third wall (Wall F). Wall F is located at the top of slope and supports a proposed flat grade including the pool area. Wall C is located on the southeast side of the site and supports the grade transition between the building pad elevation and the proposed soundwall location. Wall D is located along the North East side of the site along El Camino Real and supports a proposed ascending 2:1 slope and has a level toe condition. Wall E is located on the north end of the site and supports a proposed ascending 2:1 slope above and has a level toe condition. Wall G is located on the northem side of Black Skimmer Drive and supports the roadway. The toe of wall G is proposed adjacent to an existing drainage swale. Geotechnical Design Parameters - The geotechnical parameters provided for use in design of the Verdura Retaining walls were provided by Geocon Inc. (the geotechnical engineer for the project) which is noted as Referenced Document #1. Seisniic Design Parameters - . 15g Wall Components - The Verdura Retaining walls are to be constmcted using Verdura 40 blocks, Mirafi geogrids and other accessory products as required for constmction by the wall building contractor, and described in "Part 2 - Products" of the "Specifications" of the attached constmction drawings (Sheet 22). Wall Design - The Verdura 40 Retaining Walls proposed for this site have been designed for both static and pseudo-static conditions using computer program MSEW (Mechanically Stabilized Earth Wall) developed by AD AMA Engineering, Inc. MSEW incorporates nationally recognized methodologies in design of mechanically stabilized earth stmctures such as those adopted by the Federal Highway Mr. Matthew Jansen Verdura 40 Wall Design La Costa Village Townhomes Friday, November 18, 2011 Administration (FHWA) and National Concrete Masonry Association (NCMA). The design calculations are provided in Appendix 2 of this report and preceded by a summary page of the critical factors of safety. Our analysis is based on the AASHTO Design Method. Summary: Wall A - Double Terrace • H=13.3' w/ a proposed ascending 2:1 slope above Wall A - Triple Terrace • H=13.3' w/ a surcharge loading from wall F Wall B - Triple Terrace • H=14.3' w/ a surcharge loading from wall F Wall B - Beyond the triple terrace configuration • H=12' w/ a proposed 2:1 ascending slope above WallC WallD WallE WallF WallG • H=5.3' w/ fiat top and toe condition • H=10' w/ a flat toe condition and a proposed 2:1 ascending slope above • H=14.7 w/ a flat toe condition and a proposed 2:1 ascending slope above • H=16' w/ a proposed descending 2:1 slope at the toe and flat top condition • H=7.4' w/ a flat to variable sloping toe condition and a flat top condition Toe embedment - Toe embedment (embedment of the wall base into the foundation soils) is typically provided to minimize the potential for erosion undermining of the wall base, enhance bearing capacity and enhance sliding resistance of the basal reinforcement layers. Embedment of the wall is accounted for in the calculations as part of the "total wall height". The embedment has no impact on the wall calculations (i.e. design methodology conservatively ignores passive earth pressures from soils in front of the wall and hence has no effect on the intemal or extemal stability of the wall system/components). Toe embedment used in design exceeds the ininimum guidelines as set forth by NCMA and FHWA (H/7 [sloping toe condition], where "H" is the walls exposed height). For descending slopes we have used a minimum depth of 7' to daylight. This should be verified in the field for areas that retain above an existing slope. Also, wall G has recommendations for toe embedment due to the proximity of the adjacent stieam prepared by C & V Consulting, Inc (Appendix 1) WaU Backfill - Requirements for reinforced, retained, and foundation zone backfill materials are included in the specifications for this project. The reinforced zone materials should consist of engineered fill comprised of select on-site or imported soils accepted by the geotechnical engineer-of-record and having a minimum friction angle of 30 degrees shear strength when remolded to 90% of modified proctor density (ASTM D-1557). Additionally, the soil materials used in wall constmction should not exhibit a plasticity index (PI) greater than 20 or have % fines passing the 200 sieve > 35%. Soils within 6 inches of a reinforcing geosynthetic layer shall not contain particles larger than six inches. Mr. Matthew Jansen Verdura 40 Wall Design La Costa Village Townhomes Friday, November 18, 2011 Backfill Drainage - Retaining wall sub-drainage should be constmcted in accordance with the details shown on the accompanying constmction drawings and/or as directed by the geotechnical engineer of record. Surface Water Drainage - Drainage and channeling of surface water from above wall and from surrounding improvements should be directed to collection devices away from the retaining wall stmctures. Where possible, surface water should be collected in v-ditches, swales, or other coUection/chaimeling devices in order to contain and discharge water to either end of the wall or away from the stmctures. Berms, curbs, gutters, swales or other devices may be required to prevent excessive amount of concentrated mnoff from draining over the crest of the wall and creating erosion problems. In no case should large volumes of mnoff or concentrated fiows be allowed to cascade over the top of Verdura Walls, discharge into the backfill or infill soils from which the wall is constmcted or otherwise be allowed to saturate the stmctural fill of the wall. Improvements Above Walls - The uppermost geosynthetic reinforcements are designed to be at least 2 feet beneath the top of wall elevations. The 2-foot zone is typically considered a suitable depth in which landscaping can be installed. If deeper infrastmcture improvements are planned within the areas above the wall, there may be conflict with geosynthetic reinforcements. SRD should be contacted if infrastmcture utilities are planned for these areas and trench excavations encroach within the zone of geosynthetic reinforced soils. Additional analyses in order to assess the stability of the designed retaining wall may be required if this condition exists. Construction Details - Detailed specifications, relative to the constmction of the Verdura retaining wall system, are provided on the accompanying constmction drawings. The length, strength and spacing of geosynthetic reinforcements are depicted on a maximum height cross-section design. The minimum recommended geogrid lengths should be maintained throughout the specified lengths of the wall per the accompanying drawings. Geogrid spacing for all wall areas shall not be greater than 3 block courses except for top of wall areas as noted on the included plans. GLOBAL STABILITY ANALYSES - Global stability of soil slopes surcharged by retaining stmctures is typically independent of local stmctural design for the retaining stmcture and hence has not been conducted as part of the design included herein. The global stability of the slope and retaining stmcture combination is the responsibility of the geotechnical engineer-of-record (Geocon, Inc.) and should be provided under separate cover prior to initiation of constmction. In order to ensure that the geoteclmical engineer of record has reviewed the global stability of the proposed structures, we request that the geotechnical engineer of record provide a letter of review to SRD. The letter of review should provide confirmation that an assessment of the global stability for the slope and retaining wall combination was performed and that minimum required safety factors per the requirements of all appropriate reviewing agencies have been achieved. Mr. Matthew Jansen Verdura 40 Wall Design La Costa Village Townhomes Friday, November 18, 2011 GEOTECHNICAL ENGINEER-OF-RECORD It is the project geotechnical engineer-of-record's responsibility to review the enclosed design calculations, plans, and specifications in order to ensure that the assumptions made herein are consistent with their intentions. It should also be noted that it shall be the responsibiUty of the project geotechnical engineer-of-record to ensure that the soil and geologic stmcture on which the proposed Verdura retairung walls are founded are globally stable (i.e. stable with respect to potential failure surfaces that may occur behind and beneath the Verdura 40 retaining wall). Lastly, the geotechnical engineer of record will be responsible for ensuring that the soil, materials, and methods used in constmction of the Verdura Retaining wall are conducted in accordance with the specifications outlined herein. CONCLUSIONS Constmction of the above referenced Verdura Walls is feasible provided that the recommendations and associated details presented herein are followed. If you have any questions or require additional information, please contact the undersigned. Respectfully Submitted Niklas E. Jari^^&on, RCE 67744 Senior Eii^i: Distribi: (6) Addressee Attachments: Appendix 1 - Verdura Design Parameters Appendix 2 - Retaining Wall Design Calculations - Rear of Text Mr. Matthew Jansen Verdura 40 Wall Design La Costa Village Townhomes Friday, November 18,2011 Appendix 1 Geotechnical Design Parameters & Wall G recommendation (3 Pages) walls higher than 8 feet or other types of walls are planned, such as crib-type walls, Geocon Incorporated should be consulted for additional recommendations. 6.8 Geogrid-Reinforced Retaining Walls 6.8.1 We understand that Geogrid Reinforced Earth Walls may be used for the project. These walls consist of a reinforced earth zone cormected to modular block facing units. Typically, geogrid reinforcement is placed at specified levels of the wall, connected to the facing block units and extended behind the wall a specified distance. The type and strength of geogrid as well as the embedment depth and vertical spacing are determined based on the shear strength characteristics of the soils being reinforced and retained. 6.8.2 We recommend the following geotechnical parameters for design of the geosynthetic reinforced walls. Sufficient samples should of stockpile soils to be used as wall backfill should be obtained and tested to evaluate the suitability of the soil for use as wall backfill. TABLE 6.8 GEOTECHNiCAL PARAMETERS FOR GEOGRID REINFORCED WALLS Parameter Reinforced Zone Retained Zone Foundation Zone Angle of Intemal Friction 30 degrees 30 degrees 30 degrees Cohesion Opsf ICQ psf 100 psf Wet Unit Weight 130 pcf 130 pcf 130 pcf 6.8.3 An allowable soil bearing pressure of 2,000 psf should be used for foundation design and calculations for wall bearing. This bearing pressure assumes a minimum foundation width and depth of 12 inches. The allowable soil bearing pressure may be increased by 300 psf and 500 psf for each additional foot of foundation width and depth, respectively, up to a maximum allowable soil bearing pressure of 4,000 psf 6.8.4 The above soil parameters are based on direct shear strength tests performed durmg previous geotechnical investigations and represent some of the on-site materials. Geocon has no way of knowing whether these materials will actually be used for the wall during constmction. It is up to the wall designer to use his judgment in selection of design parameters. As such, once backfill materials have been selected and/or stockpiled, sufficient shear tests should be conducted on samples of the proposed backfill materials to verify they conform to actual design values. Results should be provided to the designer to Project No. 07193-32-03 18 April 25, 2011 Revised July 14, 2011 CONSULTING, INC. CIVIL ENGINEERING LAND PLANNING & SURVEYING November 17,2011 Mr. Nick Jansson, PE, LEED AP Vice President Soil Retention 2501 State Street Carlsbad, CA 92008 Dear Mr. Jansson: C&V Consulting, Inc. is proposing the construction ofa gravity retaining wall adjacent to an existing, natural drainage swale. The wall is being proposed in this location for environmental reasons: to reduce the project footprint and specifically, to protect the swale in quesfion in its natural state. This wall can be identified as wall G on the project improvement plans; it is approximately 48 feet long and its retained height is 2 feet. The wall will experience surcharge from a proposed street on the heel side ofthe wall; it is our assumption that a geogrid will be ufilized in the walls design and construction. The wall is proposed to be constructed within 3 feet ofthe flowllne ofthe existing swale at its closest point. The width ofthe swale varies along its length, and the side slope is on the order of 20 percent toward the proposed wall location at this crifical section. We recommend that: 1. The proposed wall be embedded 3 feet below the flowllne of the existing swale; please see wall profile attached. 2. The wall be embedded a minimum of 2 feet into competent sandstone material; and 3. Swale fiowline elevations and the exposure of competent sandstone material be verified in the field by the project surveyor and the project geotechnical engineer prior to wall construction. Swale flowllne elevations and depths of competent sandstone material shouid be compared to the design elevations ofthe bottom course ofthe all in order to ensure that the recommend embedment is attained during construction.
