CA INTRODUCTION This report presents the design parameters, design methodology, and calculations performed to design four segmental block retaining walls using Allan Block Classic units for Lake Residence, 2707 Blue Water Drive, Corona Del Mar, California. PROPOSED WALL DESCRIPTION Per the grading plan (Toal), four Allan Block walls are proposed for the subject property. The walls are labelled as Allan Block Wall #I to 44 for reference in this report. The total maximum height of the walls is 8.56ft. DESIGN METHODOLOGY The computer code AB Walls 3D Version 21 developed by Allan Block Corporation is used for the design of the wall. The computer code is based on the methods presented in National Concrete Masonry Association guidelines (NCMA 2010). The NCMA method of design of segmental block walls uses Coulomb Earth Pressure theory. AB Walls 3D program is customized for use with Allan Block and allows specifying choice of block types and geogrids reinforcement. The seismic internal stability of the Allan block segmental walls was explored using AB Walls 3D, which incorporates pseudo -static rigid body approach that adopts the Mononobe-Okabe method to calculate dynamic forces (NCMA 3rd Edition). An acceleration coefficient of 0.40g is used in the seismic analysis. The analysis was performed for different heights and surcharge conditions, as applicable. The results of the analysis are included as Appendix A. DESIGN PARAMETERS Soils Parameters Based on the recommendations provided in the geotechnical report (Coast) the following soils parameters are used for the design of the wall: Wall Parameters BLOCKS: 12 -inch deep Allan Block Classic Units weighing approximately 75 lbs each. SURCHARGE: Level backfill with surcharge. BATTER: 6 degrees to vertical. EMBEDMENT: 6" minimum for level grade or 48" minimum for downslope in front of wall. GEOGRIDS: Design is based on Mirafi Miragrid 3XT manufactured by TenCate. Other types of grids may be used upon approval by the engineer. The design of the retaining wall assumes no build up of hydrostatic pressures within the reinforced fill zone of the wall. Therefore, construction of an effective subdrain system behind the reinforced soil zone is critical to the performance of the wall. Any back -cut drain required shall be determined by the project geotechnical engineer and shall be installed per the direction of the project geotechnical engineer. ABI Engineering Consultants, Inc.

ABI Project No. 21302 Allan Block Wall Design 2707 Blue Water Dr., Corona Del Mar, CA ANALYSIS The wall design is based on the following factor of safety (FS) for stability analysis of the wall. The factors of safety are for static loading conditions are indicated below and are based on the current standard of practice. Static Analysis FSsii&g =1.50, FSBea,mg = 2.00, FS0wrh rmng = 2.00, and FSPwi-opt = 1.50 Seismic Analysis FSsudmg =I. 13, FSBearing = 1.50, FSOw,=fng =1.50, and FSPa-nit = 1.13 The summary calculations present the data and results for each section of the wall. RECOMMENDATIONS The wall shall be constructed per the details and geogrid reinforcement schedule based on the design calculations provided in this report, typical section, reinforcement schedule, and construction notes presented on drawings. The Allan Block walls shall be constructed per the manufacturer's recommended procedures. No substitution shall be allowed for blocks type or for the unit fill required within the units and behind the blocks. The foundation, retained, and backfill soils shall have the minimum shear strength properties as used for design in this report. All backfill shall be placed in loose lifts not exceeding 8 inches, moisture conditioned, and compacted to a minimum of 90% of the maximum dry density determined by Modified Proctor compaction test (ASTM D1557). The compaction tests shall be performed on backfill soils for meeting the minimum densities recommended. Any changes to foundation, retained and backfill soil properties and loading conditions on the wall should be brought to our attention. The temporary excavation back -cut, grading, ground improvement, fill settlement control, and sub -drain, and surface -drainage system for the Allan Block walls shall be per the Project Soils and Civil Engineer's recommendations.
