TEMPORARY NOTE: THE PURPOSE OF THIS DETAIL IS TO PR❑VIDE A DRAINAGE COLLECTION SYSTEM IN FILL AREAS THAT EXCEED 15 FEET OF HEIGHT.
HIGHWALL BERM 1. INSTALL THE DISCHARGE BARREL, ANTI-FLOTATION BASE, OUTLET PROTECTION, TRASH RACK AND THE FIRST MANHOLE SECTION,
800 (PHASE 2) 800 2. INSTALL BACKFILL OVER THE STORM DRAINAGE PIPE. THE HEIGHT OF THE FIRST LIFT IS A MINIMUM OF 10 FEET. THE TOP OF MANHOLE SHOULD ALWAYS
BE A MINIMUM OF 4 FEET BELOW THE EDGE OF THE EXTERIOR FILL SLOPE.
3. MAINTAIN A SUMP AROUND THE TOP OF THE MANHOLE TO HELP COLLECT SEDIMENT.
TEMPORARY TEMPORARY 4. USE TEMPORARY DIVERSIONS TO DIVERT RUNOFF TOWARDS THE MANHOLE. ONCE THE PLACEMENT OF FILL MAKES CONSTRUCTION OF TEMPORARY DIVERSIONS
HIGHWALL BERM HIGHWALL BERM WITH A 1% MINIMUM SLOPE DIFFICULT, RAISE THE FILL OVER THE DISCHARGE PIPE IN 8 FOOT HIGH LIFTS.
SLOPE BENCH PHASE 2 PHASE 3 5. REMOVE THE TRASH RACK AND INSTALL ANOTHER MANHOLE SECTION MANHOLE JOINTS SHOULD BE WRAPPED WITH A SEALANT PRIOR TO BACKFILLING AGAINST
SEE SLOPE DRAIN ( ) ( ) THE STRUCTURE.
PROPOSED 6. REINSTALL THE TRASH RACK AND PLACE COMPACTED FILL IN THE OLD SUMP,
DETAIL OVERBURDEN 7. CONTINUE TO PLACE FILL UPSTREAM OF THE RISER AND INSTALLING ADDITIONAL MANHOLE SECTIONS AS THE FILL HEIGHT INCREASES.
PHASE 2 PROPOSED PROPOSED 8. ONCE THE FILL HEIGHT HAS REACHED TO PROPOSED GRADE, REMOVE THE TRASH RACK AND INSTALL A MANHOLE TOP DESIGNED FOR A YARD INLET.
