CONS ]RUCTION NOTES
1. THE MATTING SHOULD BE A MINIMUM OF 4' WIDE EXTENDING 6" OVER THE LIP AND BURIED 6" DEEP IN A
VERTICAL TRENCH OVER THE LOWER EDGE. THE UPPER EDGE SHOULD BUTT AGAINST SMOOTHLY CUT SOD
AND BE SECURELY HELD IN PLACE WITH CLOSELY SPACED HEAVY DUTY WIRE STAPLES AT LEAST 12" LONG.
2. ENSURE THAT THE SPREADER UP IS LEVEL FOR UNIFORM SPREADING OF STORM RUNOFF.
3. CONSTRUCT THE LEVEL SPREADER ON UNDISTURBED SOIL (NOT ON FILL).
4, . CONSTRUCT A 20' TRANSITION SECTION FROM -THE DIVERSION CHANNEL TO BLEND SMOOTHLY TO THE
WIDTH AND DEPTH OF THE SPREADER. THE GRADE OF THE SPREADER SHOULD BE 0
5. DISPERSE RUNOFF FROM THE SPREADER ACROSS A PROPERLY STABILIZED SLOPE NOT TO EXCEED 10
MAKE SURE THE SLOPE IS SUFFICIENTLY SMOOTH TO KEEP FLOW FROM CONCENTRATING.
6. IMMEDIATELY AFTER ITS CONSTRUCTION; APPROPRIATELY SEED AND MULCH THE ENTIRE DISTURBED AREA
7. INSPECT LEVEL SPREADER AFTER EVERY RAINFALL UNTIL VEGETATION IS ESTABLISHED. AND PROMPTLY
MAKE NEEDED REPAIRS. AFTER THE AREA HAS BEEN STABILIZED, MAKE PERIODIC INSPECTIONS AND KEEP
VEGETATION IN A HEALTHY. VIGOROUS CONDITION.

2, The water then flows to the Erfiltration basin through a weir at
elevation 9.3 until the elevation of the water reaches the storage volune of
1B18 cf and an elevation of 9.9.
3, Then water then flows over the by-pass weir at elevation 93 with a max

1. Water enters the splitter box via a 12' CAP from drop inlet east of
the entrance road.
2. The water then flows to the infiltration basin through a weir at
elevation L83 until the elevation of the water reaches the storage volume of
227 cf and an elevationof 7.2. This exceeds the required storage of
174 cf.
3. Then water then flows over the by-pass weir at elevation 7.2 with a max.
