GENERAL NOTES: STORMWATER RUNOFF RATES WERE DETERMINED USING
THE RATIONAL METHOD FOR SMALL WATERSHEDS. THE ORANGE COUNTY
MINIMUM DESIGN STANDARDS HAVE BEEN MET AND EXCEEDED IN THE
DESIGN SHOWN HEREON. STORMWATER ROUTING OF THE EXISTING POND
UTILIZED THE SCS METHOD IN REGARDS TO DETERMINING STORMWATER
VOLUME. THESE METHODS CONTEMPLATE THEORETICAL DESIGN STORMS
AND CANNOT MODEL ALL POSSIBLE STORM EVENTS IN NATURE.
STORM DRAINAGE PIPES SHOWN HEREON ARE THE DESIGN OF VETERAN
ENGINEERING ASSOCIATES, INC. ALL STORM DRAINAGE ORIGINATING WITHIN
THE STRUCTURE AND CONNECTING TO THE STORM PIPE SYSTEM SHOWN
HEREON ARE TO BE DESIGNED BY OTHERS.
