SEEDING NOTES
1. SEED MIXTURE SHALL COMPLY WITH TABLE D.2.1.2.13 AND APPLICATION PER
D.2.1.2.6.
2. SEED BEDS PLANTED BETWEEN MAY 1 AND OCTOBER 31 WILL REQUIRE
IRRIGATION AND OTHER MAINTENANCE AS NECESSARY TO FOSTER AND
PROTECT THE ROOT STRUCTURE.
3. FOR SEED BEDS PLANTED BETWEEN OCTOBER 31 AND APRIL 30, ARMORING OF
THE SEED BED WILL BE NECESSARY. (E.G., GEOTEXTILES, JUTE MAT, CLEAR
PLASTIC COVERING)
4. BEFORE SEEDING, INSTALL NEEDED SURFACE RUNOFF CONTROL MEASURES
SUCH AS GRADIENT TERRACES, INTERCEPTOR DIKES, SWALES, LEVEL
SPREADERS AND SEDIMENT BASINS.
5. THE SEEDBED SHALL BE FIRM WITH A FAIRLY FINE SURFACE. FOLLOWING
SURFACE ROUGHENING, PERFORM ALL OPERATIONS ACROSS OR AT RIGHT
ANGLES TO THE SLOPE.
6. FERTILIZERS ARE TO BE USED ACCORDING TO SUPPLIERS RECOMMENDATIONS.
AMOUNTS USED SHOULD BE MINIMIZED, ESPECIALLY ADJACENT TO WATER
BODIES AND WETLANDS.
7. EROSION CONTROL SEEDING SHALL NOT BE USED IN AREAS SUBJECT TO WEAR
BY CONSTRUCTION TRAFFIC.
8. EROSION CONTROL SEEDING MAY BE USED IN ALL AREAS OF 5% OR LESS
SLOPE. IN AREAS BETWEEN 5 AND 10% SLOPE, EROSION CONTROL SEEDING
MAY BE USED FOR A MAXIMUM HORIZONTAL DISTANCE OF 100 FEET. USE MULCH
OR NETTING OR OTHER TREATMENTS FOR STEEPER AND LONGER SLOPES.
INSPECTION SEQUENCE

A RATE PER TABLE D.2.1.2.A.
2. MULCHES SHALL BE APPLIED IN ALL AREAS WITH EXPOSED SLOPES GREATER
THAN 2:1.
3. MULCHING SHALL BE USED IMMEDIATELY AFTER SEEDING OR IN AREAS WHICH
CANNOT BE SEEDED BECAUSE OF THE SEASON.
4. ALL AREAS NEEDING MULCH SHALL BE COVERED BY NOVEMBER 1.
SOIL STOCKPILE NOTES
1. STOCKPILES SHALL BE STABILIZED (WITH PLASTIC COVERING OR OTHER
APPROVED DEVICE) DAILY BETWEEN OCTOBER 1 TO APRIL 30.
2. IN ANY SEASON, SEDIMENT LEACHING FROM STOCK PILES MUST BE

AS STRUCTURAL FILL OR SLOPE SHALL, AT PROJECT COMPLETION, DEMONSTRATE
It
THE FOLLOWING:
(Y)

• A TOPSOIL LAYER WITH A MINIMUM ORGANIC MATTER CONTENT OF TEN
PERCENT DRY WEIGHT IN PLANTING BEDS, AND 5% ORGANIC MATTER
CONTENT IN TURF AREAS, AND A PH FROM 6.0 TO 8.0 OR MATCHING THE PH OF
r
THE ORIGINAL UNDISTURBED SOIL.
V
• THE TOPSOIL LAYER SHALL HAVE A MINIMUM DEPTH OF EIGHT INCHES EXCEPT
WHERE TREE ROOTS LIMIT THE DEPTH OF INCORPORATION OF AMENDMENTS
NEEDED TO MEET THE CRITERIA. SUBSOILS BELOW THE TOPSOIL LAYER
SHOULD BE SCARIFIED 4 TO 12 INCHES WITH SOME INCORPORATION OF THE
UPPER MATERIAL TO AVOID STRATIFIED LAYERS, WHERE FEASIBLE.
AFTER PLANTING, MULCH PLANTING BEDS WITH 2 INCHES OF ORGANIC MATERIALS.
QUALITY OF COMPOST AND OTHER MATERIALS USED TO MEET THE ORGANIC
CONTENT REQUIREMENTS:
• THE ORGANIC CONTENT FOR "PRE -APPROVED" AMENDMENT RATES CAN BE

MET ONLY USING COMPOST MEETING THE COMPOST SPECIFICATION FOR
BIORETENTION (SEE SECTION C2.6 OF THE COR SURFACE WATER DESIGN
C)
MANUAL), WITH THE EXCEPTION THAT THE COMPOST MAY HAVE UP TO 35
Q
PERCENT BIOSOLIDS OR MANURE. THE COMPOST MUST HAVE AN ORGANIC
O
MATTER CONTENT OF 40 PERCENT TO 65 PERCENT, AND A CARBON TO
6
NITROGEN RATIO BELOW 25:1. THE CARBON TO NITROGEN RATIO MAY BE AS
N
HIGH AS 35:1 FOR PLANTINGS COMPOSED ENTIRELY OF PLANTS NATIVE TO
Q
THE PUGET SOUND LOWLANDS REGION.
J
• CALCULATED AMENDMENT RATES MAY BE MET THROUGH USE OF COMPOSTED
MATERIALS AS DEFINED ABOVE; OR OTHER ORGANIC MATERIALS AMENDED TO
MEET THE CARBON TO NITROGEN RATIO REQUIREMENTS, AND NOT
EXCEEDING THE CONTAINMENT LIMITS IDENTIFIED IN TABLE 220-B, TESTING
PARAMETERS, IN WAC 173-350-220.
THE RESULTING SOIL IS CONDUCIVE TO THE TYPE OF VEGETATION TO BE
ESTABLISHED.
