RE:
HYDROLOGY EVALUATION FOR THE KELLAs RESIDENCE
SINGLE FAMILY GRADING PLAN - LONE JACK ROAD, OLIVENHAIN
A.P.N. 264-090-36
Gentlemen:
Please allow this letter to serve as an informal hydrology report
for the subject residential grading plan. Based on a field
survey, direct observations and the attached hydrology map, the
drainage basin for this site is basically the site itself, or
approximately 1.0 acres. Assuming urban drainage design, it is
conservatively estimated that the 100 year storm for this site is
approximately 2.0 CFS.
The grading plan proposes to cut down the top of the knoll at the
eastern portion of the lot and fill the west portion with the
cut material for a future horse corral or tennis court. The site
drainage will be handled by a combination of sheet flow and a
couple of area drains. Ul timately, the drainage will flow to-
wards its current location, i.e., Lone Jack Road.
Based on our observations, the attached hydrology map and the
proposed grading plan, we respectively request your acceptance of
our hydrology evaluation for this project. Should you have any
questions or comments, please feel free to contact this office or
respon, as such, with plan check comments.
