WASHINGTON STATE CODE
THE SUPREME COURT OF WASHINGTON ISSUED A RULING ON DECEMBER 29,
2016 REGARDING THE "VESTING" OF STORMWATER REGULATIONS. THIS RULING
UPHOLDS THE DEPARTMENT OF ECOLOGY'S REGULATIONS FOR APPLICATION
AND CONSTRUCTION DATES FOR PROJECTS WITH STORMWATER
REQUIREMENTS.
THE CITY OF EDMONDS HAS RECEIVED CLARIFICATION FROM THE
DEPARTMENT OF ECOLOGY ON WHAT THIS RULING MEANS FOR
DEVELOPMENT APPLICATIONS SUBMITTED PRIOR TO LOCAL STORMWATER
CODES BEING ADOPTED. THE STORMWATER CODES IN EFFECT AT THE TIME
THE APPLICATION FOR A PLAT/SUBDIVISION IS SUBMITTED APPLY TO ALL
SUBSEQUENT BUILDING PERMITS IF STORMWATER IS BEING ADDRESSED AT
THE SUBDIVISION/PLAT LEVEL. IF THE SUBDIVISION INCLUDED RESTRICTIONS
OR REQUIREMENTS FOR THE INDIVIDUAL LOTS, (E.G. MAXIMUM IMPERVIOUS
SURFACE, LID BMP'S), THOSE REQUIREMENTS SHOULD BE RECORDED FOR
EACH LOT AND MUST BE ENFORCED WHEN THE INDIVIDUAL LOT IS
DEVELOPED.
UNDER THE MUNICIPAL STORMWATER PERMITS THE ONLY PLACE THAT THE
RECENT SUPREME COURT DECISION COMES INTO PLAY IS IF THE DEVELOPER
DOES NOT START CONSTRUCTION ON THE PLAT/SUBDIVISION UNTIL AFTER
JANUARY 1, 2022.
FOR THE PURPOSES OF THE MUNICIPAL STORMWATER PERMITS BOTH
"APPLICATION" AND "START CONSTRUCTION" ARE DEFINED IN THE PERMITS.
APPLICATION MEANS AT A MINIMUM, A COMPLETE PROJECT DESCRIPTION,
SITE PLAN, AND IF APPLICABLE SEPA CHECKLIST.
START OF CONSTRUCTION MEANS AT A MINIMUM, THE SITE WORK
ASSOCIATED WITH AND DIRECTLY RELATED TO THE APPROVED PROJECT HAS
BEGUN. FOR EXAMPLE: GRADING THE PROJECT SITE TO FINAL GRADE OR
UTILITY INSTALLATION.
LANGUAGE SHALL BE INCLUDED ON THE FACE OF THE RECORDING
DOCUMENTS FOR THE PLAT/SUBDIVISION THAT STATES THE STORMWATER
CODES IN EFFECT AT THE TIME OF APPLICATION FOR THE PLAT/SUBDIVISION
SHALL APPLY, AS LONG AS CONSTRUCTION ON THE PLAT/SUBDIVISION
STARTS PRIOR TO JANUARY 1, 2022. IF CONSTRUCTION DOES NOT BEGIN
PRIOR TO THIS DATE, THE STORMWATER SYSTEM FOR THE PLAT/SUBDIVISION
SHALL BE REDESIGNED TO COMPLY WITH CURRENT CODES.

PREVENTATIVE MEASURES TO MINIMIZE WIND TRANSPORT
OF SOIL SHALL BE IMPLEMENTED WHEN A TRAFFIC HAZARD
MAY BE CREATED OR WHEN THERE IS THE POTENTIAL FOR
SEDIMENT TO BE TRANSPORTED BY WIND. WATER IS THE
MOST COMMON DUST CONTROL USED IN THE AREA. WHEN
USING WATER FOR DUST CONTROL, THE EXPOSED SOILS
SHALL BE SPRAYED UNTIL WET, BUT RUNOFF SHALL NOT
BE GENERATED BY SPRAYING. EXPOSED AREAS SHALL BE
RE -SPRAYED AS NEEDED. OIL SHALL NOT BE USED FOR
DUST CONTROL.
SOIL MANAGEMENT PLAN
RETAIN, IN AN UNDISTURBED STATE, THE DUFF LAYER AND NATIVE TOPSOIL TO THE
MAXIMUM EXTENT PRACTICABLE. IN ANY AREAS REQUIRING GRADING REMOVE AND
STOCKPILE THE DUFF LAYER AND TOPSOIL ON SITE IN A DESIGNATED, CONTROLLED
AREA, NOT ADJACENT TO PUBLIC RESOURCES AND CRITICAL AREAS, TO BE
REAPPLIED TO OTHER PORTIONS OF THE SITE WHERE FEASIBLE.
ALL AREAS SUBJECT TO CLEARING AND GRADING THAT HAVE NOT BEEN COVERED
BY IMPERVIOUS SURFACE SHALL DEMONSTRATE THE FOLLOWING:
1) A TOPSOIL LAYER WITH A MINIMUM ORGANIC MATTER CONTENT OF 5%
ORGANIC MATTER AND A PH FROM 6.0 TO 8.0 OR MATCHING PH OF THE
UNDISTURBED SOIL. 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.
2) USE COMPOST AND OTHER MATERIALS SHALL MEET WAC 173-350-100
SOIL QUALITY DESIGN CAN BE MET BY USING ONE OF THE METHODS LISTED BELOW.
OPTION 1: LEAVE UNDISTURBED NATIVE VEGETATION AND SOIL, AND PROTECT FORM
COMPACTION DURING CONSTRUCTION
OPTION 2: AMEND EXISTING SITE TOPSOIL OR SUBSOIL EITHER AT DEFAULT
"PRE -APPROVED" RATES, OR AT CUSTOM CALCULATED RATES BASED ON TESTS OF
THE SOIL AND AMENDED.
OPTION 3: STOCKPILE EXISTING TOP DURING GRADING, AND REPLACE IT PRIOR TO
PLANTING. STOCKPILED TOPSOIL MUST ALSO BE AMENDED IF NEEDED TO MEET THE
ORGANIC MATTER OR DEPTH REQUIREMENTS, EITHER AT A DEFAULT
"PRE -APPROVED" RATE OR AT A CUSTOM CALCULATED RATE.
OPTION 4: IMPORT TOPSOIL MIX OF SUFFICIENT ORGANIC CONTENT AND DEPTH TO
MEET REQUIREMENTS.
SEE SOIL AMENDMENT QUALITY NOTE ON THIS SHEET FOR AMENDED GUIDELINES
REFER TO BMP T5.13 IN THE WESTERN WASHINGTON STORMWATER MANUAL FOR
FURTHER DIRECTION.

BMP: CONCRETE HANDLING
(REFERENCE 2005 WASHINGTON STATE DOE STORMWATER MANUAL)
PURPOSE: CONCRETE WORK CAN GENERATE PROCESS WATER AND
SLURRY THAT CONTAIN FINE PARTICLES AND HIGH pH,
BOTH OF WHICH CAN VIOLATE WATER QUALITY
STANDARDS IN THE RECEIVING WATER. THIS BMP IS
INTENDED TO MINIMIZE AND ELIMINATE CONCRETE
PROCESS WATER AND SLURRY FROM ENTERING
WATERS OF THE STATE.
DESIGN: CONCRETE TRUCK CHUTES, PUMPS AND INTERNALS
SHALL BE WASHED OUT ONLY INTO FORMED AREAS
AWAITING INSTALLATION OF CONCRETE OR ASPHALT.
(CONCRETE TRUCK CHUTES, PUMPS, ETC. SHALL NOT
BE WASHED IN SUBGRADE AREAS OF PROPOSED
POROUS ASPHALT/INFILTRATION)
WHEN NO FORMED AREAS ARE AVAILABLE, CONTAIN
WASHWATER AND LEFTOVER PRODUCT IN A LINED
CONTAINER. DISPOSE OF WASHWATER IN A MANNER
THAT DOES NOT VIOLATE GROUNDWATER OR
SURFACE WATER QUALITY STANDARDS.
UNUSED CONCRETE REMAINING IN THE TRUCK AND
PUMP SHALL BE RETURNED TO THE ORIGINATING
BATCH PLANT FOR RECYCLING.
HAND TOOLS SHALL BE WASHED OFF ONLY INTO
FORMED AREAS AWAITING INSTALLATION OF
CONCRETE OR ASPHALT.
EQUIPMENT THAT CANNOT BE EASILY MOVED, SUCH
AS CONCRETE PAVERS, SHALL BE WASHED IN AREAS
THAT DO NOT DIRECTLY DRAIN TO A NATURAL OR
CONSTRUCTED STORMWATER CONVEYANCES.
WASHDOWN FROM AREAS SUCH AS CONCRETE
AGGREGATE DRIVEWAYS SHALL NOT DRAIN DIRECTLY
