SCT 312022 Report No. 8
Attention: Mr. Walt Wood
SUBJECT: Tanglewood Subdivision, Carlsbad, California.
Gentlemen:
In accordance with the conversation between Mr. Walt Wood and the under-
signed, we herewith submit the following comments.. The recommendations
previously submitted by Southern California Testing Laboratory, Inc. re-
garding the preparation of foundation soils and foundation reinforcement
for structures constructed within the existing fault zone have been com-
plied with in those building pads and foundations constructed within the
model area. The recommendations were as follows:
The natural soils exposed within 3 feet of finished grade have been
removed and recompacted to 90 percent of maximum dry density. Fur-
ther, all foundations which will encroach on an area 15 feet wide
along the fault trace will be reinforced with two No. 4 bars placed
3 inches above the base of the foundation and two No. 4 bars placed
3 inches below finish floor.
