Re: Grading Plan No. 9073-G
1231 Orpheus Avenue, Leucadia

JN02-001B
To Whom It May Concern,
On 12/30/05 we surveyed the graded site for the above referenced project and found the grading
to be completed in general conformance with the approved grading plan as shown on the attached
portion of the grading plan. We took approximately 50 survey shots at various locations on the
graded portion of the site that confirmed the following:
1) The grades on the pad portion of the site generally conformed to the proposed contours
shown on the plan;
2) The "restored slope" was constructed at a maximum steepness of 1.5 : 1;
3) The drainage dispersion constructed to retain and disperse drainage at the low point of
the pad portion of the site was constructed at the location and grades shown on the
plan.
Refer to the Report of Certification of Compacted Fill Ground prepared by North County Compaction
Engineering, Inc dated December 6, 2004 for detailed compaction testing results.
It appears as though the reconstructed slope has been planted as recommended in the soils report.
Please feel free t II if there an estions regarding the completed grading.

Directions for APPP=00111:
(1) From precipitation maps determine 6 hr and 24 hr amounts
for the selected frequency. These maps are included in the:
County Hydrology Manual (10, 50, and 100 yr maps included
in the Design and Procedure Manuel). 'that it is within
(2) Adjust 6 hr precipitation (if necessary)
the range of 45% to 65% of the 24 hr prat Prfation (not
applicapleto Desert).
(3) Plot 6 hr precipitation on the tight side of the chart.
(4) Draw a line through the point parallel to the plotted lines.
(5) This line is the intensity-duration curve for the location
