SHALL HAVE FREE -FLOWING, POSITIVE DRAINAGE TO AN APPROVED
STORMWATER CONVEYANCE SYSTEM OR TO AN APPROVED OUTFALL
LOCATION.
B. OUTLETS ON EACH LOT SHALL BE LOCATED WITH A FIVE-FOOT
HIGH, 2 X 4 STAKE MARKED "STORM". THE STUB -OUT SHALL EXTEND
ABOVE SURFACE LEVEL, BE VISIBLE AND BE SECURED TO THE STAKE.
C. PIPE MATERIAL SHALL CONFORM TO UNDERDRAIN SPECIFICATIONS
DESCRIBED IN KCRS 7.04 AND, IF NONMETALLIC, THE PIPE SHALL
