Subject: Response to Los Angeles County Geologic Review
Sheet dated January 4, 1979 concerning Tract 34160,
Diamond Bar, Los Angeles County, California.
References: Rough Grade Soils Engineering and Geologic Report

Gentlemen:
In response to the subject geologic review sheet we offer the
following comments:
Slopes on Lots 20-23, 26-28, 32-34 and 45-46
The geologic structure shown on the slopes between Lots 20-21,
21-22, 22-23, 26-27, 27-28, 32-33, 33-34, and 45-46 was included
for completeness, however these slopes were removed during the
process of grading. The lots and slopes in question are now
composed entirely of fill as shown on the grading plans enclosed
with the referenced report.
A portion of the slopes between Lots 45-46 and the slopes at the
rear of Lot 46 exposes massive Puente formation sandstone and
topsoil and is considered stable as constructed.
Please contact us at your convenience if there are any questions
concerning this letter.
Respectfully submitted,
