We have reviewed the report as requested In your letter of 17 July 1973. The
report provides a comprehensive, but general, analysis of the environmental resources
within this area. Our comments pertain only to drainage problems that may arise
from the project.
1. The project area is within the boundaries of the San Diego County Flood
Control District. Therefore storm drainage systems should meet the standards
of the District and be approved by the District.
2. The hydrologic analysis of storm runoff appears to be low. Since the site
contains 60 acres and there is offsite drainage area contributing to flows,
we presume that even with a low, future density of 0-2 dwellings par acre
we can anticipate a runoff greater than stated.
3. The soil strata of sandy loam on a 7 per cent slope would appear to have a
high potential for erosion, rather than a slight potential, particularly if
grading.continues during the storm season. However the effects could be
mitigated by requiring erosion control measures to be implemented if grading
is allowed during the storm season.
k. The statement on increased runoff (page 20) appears to be inappropriate.
Intense storms will increase the runoff not "vary from near zero."
5. The statement (on page 30) diverting drainage from its natural path into
Canyon de las Encinas would constitute a legal problem on surface waters.
The diversion would have to be approved by all downstream property owners
affected by the diversion.
