Anchor Retaining Wall Structural Calculations for La Costa Town Square - Office City of Carlsbad, CA March 20, 2012 W.O. #484-000 Prepared by: Matthew M. Merritt, P.E Red One Engineering, Inc. 1295 Distribution Way Vista, Ca 92081 Prepared for: O’Day Consultants, Inc. 2710 Loker Avenue West, Suite 100 Carlsbad, Ca 92010 1'ed one engineering inc 1295 distribution way, vista, california 92081 phone 760.410.1665 facsimile 760.509.0078 matt@red1engineering.com March 20, 2012 W.O. #484-000 O’Day Consultants, Inc. 2710 Loker Avenue West, Suite 100 Carlsbad, CA 92010 Attention: Mr. Tim Carroll Subject: Anchor Retaining Wall Structural Calculations La Costa Town Square - Office City of Carlsbad, California Please find enclosed the structural wall calculations for the La Costa Town Square - Office retaining wall. The Anchor retaining wall was designed using the SRWall 4.0 design software developed by National Concrete Masonry Association. The retaining walls have been designed for internal and external wall stability only. The Geotechnical Engineer of Record shall confirm site global stability. The General contractor/developer shall coordinate the installation of all subterranean construction within the reinforced zone of the Anchor walls. Red One Engineering, Inc. shall be consulted prior to any excavation within the reinforced zone. All efforts shall be made to coordinate the installation of subterranean features during wall construction to limit future disturbance of the geogrid reinforcement. Anchor Retaining Wall Systems are active systems and may exhibit slight movement or creep over time as the geogrid reinforcement elongate to develop full tensile resistance. The owner should be aware that structures and pavement placed within the reinforced or retained zones of the wall may undergo movement that can lead to surface cracking. It is recommended that the compacted soil in the reinforced and retained zones be allowed to consolidate for a time up to 45 days to allow for the elongation of the geogrid reinforcement. This will allow for any slight movement or creep to occur before placement of structures or pavement on top of the fill and further mitigate the possibility of surface cracking. It is also recommended a maintenance program be implemented by the property owner to monitor and repair any cracking in the finished surface above the Anchor retaining wall to prevent water infiltration and hydrostatic pressures. 1'ed one engineering inc 1295 distribution way, vista, california 92081 phone 760.410.1665 facsimile 760.509.0078 matt@red1engineering.com Soil design parameters are based upon the Geotechnical Investigation by Southern California Soil & Testing, Inc. dated January 4, 2012. All soil design parameters shall be confirmed by the geotechnical engineer prior to the commencement of construction. The owner shall provide a special inspector, approved by the City of Carlsbad, to observe the wall installation to satisfy the special inspection requirements as noted on the Title Sheet and Notes of the Anchor Retaining Wall Plans. Please contact the undersigned with any questions regarding the Anchor Retaining Wall Structural Calculations or the Anchor Retaining Wall Plans. Sincerely, Red One Engineering, Inc. Matthew M.
