Dear Mr. Weidner:
At your request the engineering staff of the Grading
Division reviewed the grading plans, hydrology and the
field conditions of Tract 7561.
The primary concern was the finished elevation of the
lots along the easterly boundary of the tract, e.g, lots
1-21. Additional concerns that were expressed and also
investigated consisted of a "trough" or terrace along the
easterly boundary and a channel located outside of the
tract boundary along the southerly end of said tract.
The lot elevations that were your primary concern are too
far along in the construction cycle to be lowered. Lowering
the elevation of these lots would require extensive regrading
of the entire tract and would disrupt the established
drainage patterns for this development. Prior to approval
of the grading plan by this Division, the civil engineer
who designed this tract was required to submit a plan for
drainage, establish volumes of storm waters which would re-
quire disposal, and provide the necessary drainage devices
to make this a safe and stable development.
The "trough" or terrace along the easterly boundary with
tract 6969 (Troy Homes) will only be required to carry the
waters that fall directly on it and the slope immediately
above it. The drainage calculations from the design civil
engineer for tract 7561 indicates that this trough is more
than adequate in its present condition.

The channel along the southerly boundary is under the
jurisdiction of the Orange County Flood Control District and
meets all of the requirements for a trapezoidal channel.
This device will not adversely effect the proposed develop-
ment of tract 7561.
I concur with your suggestion, Don, that cross sections
through proposed and existing developments might help your
City Council and Planning Commission evaluate the effects of
future developments on existing ones prior to approval by
these bodies. In this particular case, it would have been
extremely helpful and would have allowed the design civil
engineers the opportunity to provide a more compatible
development.
If I can be of any further assistance, please feel free to
call.
Ver truly yours,
C. E. HOLLON
