SUBJECT: Construction of Retaining Walls Adjacent to Toe of Carlsbad Village Drive
Embankment (North Side), Pacific View Estates, Phase II, Units 1 and 3 ,
Carlsbad Tract #96-03, City of Carlsbad, California.
REFERENCE: Grading Plans (Sheets 1 through 5) for Pacific View Estates, Phase II, Units 2
and 3, Carlsbad Tract #96-03, Prepared by Dudek and Associates, Undated.
Gentlemen:
At your request, we reviewed the refere_nced grading plans pertaining to the proposed retaining
walls adjacent to the northern toe of the embankment supporting Carlsbad Village Drive. The
I
plans indicate that the walls are proposed within Lots 21, 22, 23 and 26 of the subject tract. The
maximum height of the wall proposed would be on the order of 8 feet. We understand, that the
proposed wall construction would require back cut into the subject toe portion of the embankment
supporting Carlsbad Village Drive.-However, the fill conditions at the proposed back cut location
are unknown at this time. Based on our previous study, we believe the embankment fill is
generally present in a medium dense state. On the basis of our limited study, and engineering
experience and judge~ent, we recommend test pits be excavated within the proposed wall back

cut areas prior to the construction of walls, or during the mass grading of the subject tract. At that
time field conditions will be evaluated and a geotechnical summary report will be prepared by this
office addressing the temporary stability of the embankment and recommendations regarding the
construction of the walls and its backfills.
If you have questions after reviewing the findings and recommendations contained in this report,
please do not hesitate 'to contact this office. This opportunity to be of professional service is
sincerely appreci_ated.
