Rigid Pipe NOTES:
1. Pipe compaction limits shown on this plan are for pipe
construction in an embankment. For pipe construction
in a trench, the horizontal limits of the pipe compaction
zone shall be the walls of the trench.
2. All steel and aluminum pipe and pipe -arches shall be
installed in accordance with design A.
3. Concrete pipe with elliptical reinforcement shall be
installed in accordance with design A.
4. Concrete pipe, plain or with circular reinforcement, shall
be installed with design A.
5. O.D. is equal to the outside diameter of a pipe or the
outside span of pipe -arch. The dimensions shown as
O.D. with 3' maximum shall be O.D. until O.D. equals

Flexible Pipe NOTES:
1. Provide uniform support under barrels.
2. Hand tamp under haunches.
3. Compact bedding material to 95% max. density; directly
over pipe, hand tamp only.
4. See "Excavation and Preparation of Trench" in sanitary
sewers section of the standard WSDOT/APWA
specifications for trench width "W" and trenching
Options. The pipe zone will be the actual trench width.
The minimum concrete width shall be 11 I.D. = 18".
5. Trench backfill shall conform to "Backfilling Sewer
Trenches" in the sanitary sewers section of the
WSDOT/APWA standard specifications, except that
rocks or lumps larger than 1" per foot of pipe diameter
shall not be used in the backfill material.
6. See "Bedding Material for Flexible Pipe" in aggregates
section of the WSDOT/APWA standard speciflceflons
for the material specifications.

1.2. MAY BE USED ANYWHERE AT THE APPLICANT'S DISCRETION TO PROTECT DRAINAGE SYSTEM.
1.3. THE CONTRIBUTING DRAINAGE AREA MOST NOT BE LARGER THAN 1 ACRE.
2. DESIGN AND INSTALLATION SPECIFICATIONS
2.1. FILTER FABRIC IS ONLY ALLOWED WERE PONDING WILL NOT BE A TRAFFIC CONCERN AND WHERE SLOPE EROSION WILL NOT RESULT IF THE
CURB IS OVERTOPPED BY PONDED WATER.
2.2. THE PLACEMENT OF A FILTER FABRIC UNDER GRATES IS GENERALLY PROHIBITED AND THE USE OF FILTER FABRIC OVER GRATES IS STRICTLY
LIMITED AND DISCOURAGED.
3. MAINTENANCE STANDARDS
3.1. ANY ACCUMULATED SEDIMENT ON OR AROUND INLET PROTECTION SHALL BE REMOVED IMMEDIATELY. SEDIMENT SHALL NOT BE REMOVED

NOTES
1. CONDITION OF USE
1.1. SILT FENCE MAY BE USED DOWNSLOPE OF ALL DISTURBED AREAS.
1.2. SILT FENCE IS NOT INTENDED TO TREAT CONCENTRATED FLOWS, NOR IS INTENDED TO TREAT SUBSTANTIAL AMOUNTS OF OVERLAND FLOW.
ANY CONCENTRATED FLOW MOST BE CONVEYED THROUGH THE DRAINAGE SYSTEM TO A SEDIMENT TRAP OR POND.

2.2. STANDARD STRENGTH FABRIC REQUIRES WIRE BACKING TO INCREASE THE STRENGTH OF THE FENCE. WIRE BACKING OR CLOSER POST
SPACING MAY BE REQUIRED FOR EXTRA STRENGTH FABRIC IF FIELD PERFORMANCE WARRANTS A STRONGER FENCE.
2.3. WHERE THE FENCE IS INSTALLED, THE SLOPE SHALL NOT BE STEEPER THAN 2H:1 V
2.4. IF A TYPICAL SILT FENCE IS USED, THE STANDARD 4X4 TRENCH MAY NOT BE REDUCED AS LONG AS THE BOTTOM 8 INCHES OF THE SILT FENCE
S WELL BURIED AND SECURE IN A TRENCH THAT STABILIZES THE FENCE AND DOES NOT ALLOW WATER TO BYPASS OR UNDERMINE THE SILT
FENCE.
3. MAINTENANCE STANDARDS
3.1. ANY DAMAGE SHALL BE REPAIR IMMEDIATELY.
3.2. IF CONCENTRATED FLOES ARE EVIDENT UPHILL OD THE FENCE, THEY MUST BE INTERCEPTED AND CONVEYED TO A SEDIMENT TRAP OR POND.
3.3. T IS IMPORTANT TO CHECK THE UPHILL SIDE OF THE FENCE FOR SIGNS OF THE FENCE CLOGGING AND ACTING AS A BARRIER TO FLOW AND
THEN CAUSING CHANNELIZATION OF FLOWS PARALLEL TO THE FENCE. IF THIS OCCURS, REPLACE THE FENCE OR REMOVED THE TRAP
SEDIMENT.
3A SEDIMENT MOST BE REMOVED WHEN SEDIMENT IS 6 INCHES HIGH.
3.5. IF THE FILTER FABRIC (GEOTE)CTILE) HAS DETERIORATED DUE TO ULTRAVIOLET BREAKDOWN, IT SHALL BE REPLACED.
