Attention: Mr. Tim Carroll
Subject: Anchor Retaining Wall Structural Calculations
La Costa Town Square -Residential
City of Carlsbad, California
w.o. #491-000
Please find enclosed the structural wall calculations for the La Costa Town
Square -Residential retaining walls. The Anchor retaining wall was designed
using the SRWaIl4.0 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.

Soil design parameters are based upon the Geotechnical Investigation by
Southern California Soil & Testing, Inc. dated January 3,2012. 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.
