MONITORING PLAN:
PLAN GOALS, OBJECTIVES, AND PERFORMANCE STANDARDS:
PLAN GOALS, OBJECTIVES, AND PERFORMANCE STANDARDS ARE OUTLINED IN TABLE 1 (THIS SHEET). THE
GOALS AND OBJECTIVES OF THIS PLAN ARE CONSIDERED ACHIEVED WHEN THE PERFORMANCE STANDARDS
ARE SATISFIED.
MONITORING PLAN (DURATION: 5 YEARS):
AS‐BUILT
SCHEDULE: IMMEDIATELY FOLLOWING CONSTRUCTION
FOLLOWING COMPLETION OF THE WORK SHOWN ON THIS PLAN, A QUALIFIED PROFESSIONAL SHALL
PREPARE AN AS‐BUILT OF THE WORK COVERED BY THIS PLAN. THE AS‐BUILT SHALL SUMMARIZE THE
COMPLETED WORK AS WELL AS ANY DEVIATIONS FROM THE APPROVED VERSION OF THIS PLAN.
IN ADDITION TO THE AS‐BUILT, BASELINE MONITORING DATA SHALL BE COLLECTED AND PERMANENT
PHOTO POINTS SHALL BE ESTABLISHED TO PHOTOGRAPHICALLY DOCUMENT REPRESENTATIVE CONDITIONS
WITHIN THE WORK AREAS SHOWN ON THIS PLAN. BASELINE MONITORING DATA COLLECTED AND REPORTED
AS PART OF THE AS‐BUILT SHALL BE CONSISTENT WITH THAT DESCRIBED FOR ANNUAL MONITORING.
THE AS‐BUILT AND BASELINE MONITORING DATA SHALL BE SUBMITTED TO THE CITY OF FEDERAL WAY NO
LATER THAN 30 DAYS FROM THE DATE THAT THE WORK SHOWN ON THIS PLAN HAS BEEN COMPLETED.
ANNUAL MONITORING
FOLLOWING ACCEPTANCE OF THE AS‐BUILT, ANNUAL MONITORING SHALL BE COMPLETED FOR A PERIOD OF
FIVE (5) YEARS. MONITORING SHALL BE COMPLETED BY A QUALIFIED PROFESSIONAL AND SHALL COMPRISE
A DETAILED SITE ASSESSMENT PER THE ABOVE SCHEDULE WITH REPORTING TO THE CITY OF FEDERAL WAY
NO LATER THAN 30 DAYS FOLLOWING EACH MONITORING ASSESSMENT.
THE PURPOSE OF ANNUAL MONITORING IS TO EVALUATE CONDITIONS WITHIN THE WORK AREAS SHOWN
ON THIS PLAN PER THE CURRENT YEAR'S PERFORMANCE STANDARDS. THE FOLLOWING INFORMATION
SHALL BE COLLECTED AND ASSESSED RELATIVE TO THE PERFORMANCE STANDARDS ESTABLISHED FOR THE
PROJECT:
THE PERCENT SURVIVAL OF INSTALLED PLANT STOCK (YEAR 1 THROUGH YEAR 2 ONLY). A DIRECT COUNT
INVENTORY AND ASSESSMENT OF ALL INSTALLED PLANTS SHALL BE USED TO EVALUATE PERCENT
SURVIVAL. THE RATIONALE FOR POOR CONDITIONS, IF PRESENT, WILL BE DETERMINED TO THE EXTENT
FEASIBLE.
THE PERCENT COVERAGE PROVIDED BY INSTALLED PLANT SPECIES (ALL YEARS). INSTALLED PLANT STOCK
PERCENT COVERAGE SHALL BE ASSESSED USING APPROPRIATELY SIZED SAMPLE PLOTS OR LINE INTERCEPT
TRANSECTS.
THE PERCENT COVERAGE PROVIDED BY NOXIOUS WEEDS (ALL YEARS). INSTALLED PLANT STOCK PERCENT
COVERAGE SHALL BE ASSESSED USING APPROPRIATELY SIZED SAMPLE PLOTS OR LINE INTERCEPT
TRANSECTS.
PHOTOGRAPHS OF THE WORK AREAS SHOWN ON THIS PLAN SHALL BE TAKEN FROM THE PERMANENT
PHOTO POINTS ESTABLISHED DURING THE AS‐BUILT.
CONTINGENCY PLAN:
SHOULD ANY MONITORING ASSESSMENT REVEAL THAT THE PERFORMANCE STANDARDS FOR THE
RESPECTIVE YEAR ARE NOT SATISFIED, THE PERMITTEE SHALL WORK WITH THE CITY OF FEDERAL WAY TO
DEVELOP A CONTINGENCY PLAN TO ADDRESS THE DEFICIENCY(IES). CONTINGENCY PLANS CAN INCLUDE,
BUT ARE NOT LIMITED TO, THE FOLLOWING ACTIONS:
1. ADDITIONAL PLANT INSTALLATION;
2. EROSION CONTROL;
3. HERBIVORY PROTECTION;
4. MODIFICATION TO THE IRRIGATION REGIME; AND/OR
5. PLANT SUBSTITUTIONS OF TYPE, SIZE, QUANTITY, AND LOCATION.
SUCH CONTINGENCY PLAN SHALL BE SUBMITTED TO THE CITY OF FEDERAL WAY BY JANUARY 31 OF ANY
YEAR WHEN DEFICIENCIES ARE DISCOVERED. UNLESS OTHERWISE APPROVED BY THE CITY OF FEDERAL WAY,
ACTIONS SPECIFIED ON AN APPROVED CONTINGENCY PLAN MUST BE COMPLETED WITHIN 60 DAYS. IF THE
FAILURE IS SUBSTANTIAL, THE CITY OF FEDERAL WAY MAY EXTEND THE COMPLIANCE MONITORING PERIOD
FOR THE ENHANCEMENT WORK.
MAINTENANCE PLAN:
THIS SECTION PROVIDES A GENERAL OVERVIEW OF THE MAINTENANCE PROGRAM NECESSARY TO ENSURE
THE PERFORMANCE STANDARDS ESTABLISHED FOR THIS PLAN ARE SATISFIED.
GENERAL MAINTENANCE
INSTALLED PLANTS SHALL BE MAINTAINED AT REGULAR INTERVALS DURING THE MONITORING PERIOD TO
PROMOTE SUCCESSFUL ESTABLISHMENT AND VIGOROUS GROWTH.
GENERAL MAINTENANCE SHALL INCLUDE:
WEEDING THE BASE OF EACH INSTALLED PLANT.
RE‐APPLYING BARK MULCH TO MAINTAIN A 6" MINIMUM APPLIED THICKNESS ‐ YEAR 1 ONLY.
THE PRUNING OF INSTALLED PLANTS TO REMOVE DEAD WOOD AND PROMOTE VIGOROUS PLANT
GROWTH AND PROPER FORM.
THE REPLACEMENT OF PLANTS IN DISTRESS AND/OR THAT ARE DISEASED.
THE REMOVAL OF TRASH, LITTER, AND/OR OTHER NON‐DECOMPOSING DEBRIS.
TEMPORARY IRRIGATION.
NOXIOUS WEED CONTROL
FOLLOWING PLANT INSTALLATION AND AT REGULAR INTERVALS DURING THE MONITORING PERIOD,
NOXIOUS WEED CONTROL SHALL OCCUR ON A SPOT TREATMENT BASIS WITHIN EACH WORK AREA. TARGET
NOXIOUS WEED SPECIES SHALL INCLUDE THE FOLLOWING: ALL CLASS "A", "B", AND "C" NOXIOUS WEEDS
(INCLUDING NON‐REGULATED "B" AND "C" NOXIOUS WEEDS) IDENTIFIED ON THE LATEST SNOHOMISH
COUNTY NOXIOUS WEED LIST. DURING NOXIOUS WEED CONTROL WORK, EXISTING NATIVE VEGETATION
SHALL BE PROTECTED FROM DAMAGE. ALL NOXIOUS WEED CONTROL CUTTINGS AND DEBRIS SHALL BE
REMOVED FROM THE SITE.
ENVIRONMENTAL GOALS & OBJECTIVES:
TO SUCCESSFULLY ESTABLISH A DENSE NATIVE PLANT
COMMUNITY COMPRISING TREES AND SHRUBS WITHIN
THE AREAS SHOWN ON THIS PLAN.
TO LIMIT NOXIOUS WEED SPECIES WITHIN THE AREAS
SHOWN ON THIS PLAN.

PERFORMANCE STANDARDS:
1.PLANT SURVIVAL:
100% SURVIVAL BY INSTALLED PLANT STOCK AFTER THE FIRST GROWING SEASON. THIS STANDARD CAN
BE ACHIEVED STRICTLY THROUGH SURVIVAL OR THROUGH A COMBINATION OF SURVIVAL AND PLANT
REPLACEMENT.
80% SURVIVAL BY INSTALLED PLANT STOCK AFTER THE SECOND GROWING SEASON.
2.NATIVE PLANT COVERAGE:
YEAR 3: 30%
YEAR 5: 60%
UP TO 20% OF THE NATIVE WOODY PLANT SPECIES COVERAGE DURING ANY YEAR MAY BE COMPRISED OF
DESIRABLE NATIVE COLONIZING SPECIES.
3. NATIVE PLANT DIVERSITY:
AFTER THE FIFTH GROWING SEASON, A MINIMUM OF FIVE DIFFERENT PLANT SPECIES WILL BE
ESTABLISHED WITHIN BUFFER AREAS.
LESS THAN 10% COVERAGE BY ALL CLASS "A", "B", AND "C" NOXIOUS WEEDS (INCLUDING NON‐REGULATED
"B" AND "C" NOXIOUS WEEDS) IDENTIFIED ON THE LATEST SNOHOMISH COUNTY NOXIOUS WEED LIST.
