Dear Mr. and Mrs. Brown:
In reference to the city of Carlsbad subject letter, Item 1, regarding surface drainage
directed along the narrow side yard area, the following conclusions and
recommendations are presented.
CONCLUSIONS AND RECOMMENDATIONS
1) Infiltration of water adjacent to foundations and retaining walls can potentially
adversely affect conventional footings and create "damp" conditions in
subterranean structures. The following recommendations are intended to reduce
these concems.

2) The six (6) foot wide northem side yard area will slope to the west at a grade of
about three (3) percent. The upper 12 inches of the subgrade deposits in the side
yard area should be scarified and compacted to a minimum of 95 percent of the
laboratory maximum dry density.
3) A portion of the residence adjacent to the side yard area will be supported on
conventional footings. These footings should be deepened an additional six (6)
inches.
4) Positive drainage should be maintained along the side yard area.
If you have any questions, please do not hesitate to contact us at (858) 755-8622. This
opportunity to be of service is appreciated.
