PLAN GOALS, OBJECTIVES, AND PERFORMANCE STANDARDS
PLAN GOALS, OBJECTIVES, AND PERFORMANCE STANDARDS ARE OUTLINED IN
THE TABLE BELOW. THE GOALS AND OBJECTIVES OF THIS PLAN ARE CONSIDERED
ACHIEVED WHEN THE PERFORMANCE STANDARDS ARE SATISFIED.
COMPLIANCE MONITORING PLAN
AS‐BUILT
FOLLOWING COMPLETION OF THE ENHANCEMENT WORK SHOWN ON THIS
PLAN, A QUALIFIED PROFESSIONAL SHALL PREPARE AN AS‐BUILT OF THE
COMPLETED WORK. THE AS‐BUILT SHALL SUMMARIZE THE COMPLETED WORK
AND ANY DEVIATIONS FROM THE APPROVED VERSION OF THIS PLAN. IN
ADDITION, THE AS‐BUILT SHALL CONTAIN BASELINE MONITORING DATA AND
PHOTOGRAPHS OF EACH ENHANCEMENT AREA.
FOLLOWING PLANT INSTALLATION, PERMANENT COMPLIANCE MONITORING
PLOTS OR TRANSECTS SHALL BE ESTABLISHED TO DOCUMENT BASELINE
VEGETATION CHARACTERISTICS WITHIN EACH ENHANCEMENT AREA.
COMPLIANCE MONITORING PLOTS AND TRANSECTS SHALL BE SCALED
APPROPRIATELY TO ACCURATELY SAMPLE THE FOLLOWING: NATIVE WOODY
PLANT SPECIES (TREES AND SHRUBS) AND NOXIOUS WEED SPECIES. BASELINE
COMPLIANCE MONITORING DATA SHALL BE COLLECTED AT THE TIME OF THE
AS‐BUILT USING THE ESTABLISHED SAMPLE PLOTS OR TRANSECTS (SEE "ANNUAL
COMPLIANCE MONITORING" FOR FIELD DATA COLLECTION REQUIREMENTS).
PERMANENT PHOTO POINTS SHALL BE ESTABLISHED TO PHOTOGRAPHICALLY
DOCUMENT REPRESENTATIVE CONDITIONS WITHIN EACH ENHANCEMENT AREA.
BASELINE PHOTOGRAPHS SHALL BE TAKEN AT THE TIME OF THE AS‐BUILT.
THE AS‐BUILT AND BASELINE MONITORING DATA SHALL BE SUBMITTED TO THE
CITY OF RENTON NO LATER THAN 30 DAYS FROM THE DATE THAT THE WORK
SHOWN ON THIS PLAN HAS BEEN COMPLETED.
ANNUAL COMPLIANCE MONITORING
FOLLOWING ACCEPTANCE OF THE AS‐BUILT BY THE CITY OF RENTON, ANNUAL
COMPLIANCE MONITORING SHALL BE COMPLETED FOR A PERIOD OF FIVE (5)
YEARS. ANNUAL COMPLIANCE MONITORING SHALL BE COMPLETED BY A
QUALIFIED PROFESSIONAL AND SHALL COMPRISE A SITE INVESTIGATION AND
REPORTING PER THE FOLLOWING INTERVAL:
QUARTERLY DURING THE FIRST YEAR (YEAR 1) FOLLOWING PLANT
INSTALLATION; AND
IN AUGUST OR SEPTEMBER OF THE SECOND THROUGH FIFTH YEARS
(YEAR 2 THROUGH YEAR 5) FOLLOWING INITIAL PLANT INSTALLATION.
MONITORING REPORTS SHALL BE SUBMITTED TO THE CITY OF RENTON NO
LATER THAN 30 DAYS FOLLOWING EACH MONITORING ASSESSMENT.
MONITORING SHALL COMPRISE A QUANTITATIVE ASSESSMENT OF CONDITIONS
WITHIN EACH ENHANCEMENT AREA FOR PURPOSES OF EVALUATING THE
CURRENT YEAR'S PERFORMANCE STANDARDS. AT THE TIME OF EACH
MONITORING ASSESSMENT, THE FOLLOWING INFORMATION SHALL BE
COLLECTED WITHIN EACH ENHANCEMENT AREA AND ASSESSED RELATIVE TO
THE SUCCESS STANDARDS ESTABLISHED FOR THE PROJECT:
THE CONDITION OF INSTALLED PLANT STOCK INCLUDING
SURVIVORSHIP, HEALTH, AND VIGOR. THE RATIONALE FOR POOR
CONDITIONS, IF PRESENT, WILL BE DETERMINED.
THE SPECIES COMPOSITION OF AND AREAL COVERAGE PROVIDED BY
NATIVE WOODY PLANT SPECIES (TREES AND SHRUBS).
THE SPECIES COMPOSITION OF AND AREAL COVERAGE PROVIDED BY
NOXIOUS WEED SPECIES.
A DIRECT COUNT INVENTORY AND ASSESSMENT OF ALL INSTALLED PLANT STOCK
SHALL BE USED TO EVALUATE PLANT STOCK CONDITIONS. SPECIES
COMPOSITION AND AREAL COVERAGE SHALL BE ASSESSED USING THE SAMPLE
PLOTS OR TRANSECTS ESTABLISHED DURING THE AS‐BUILT.
IN ADDITION TO FIELD DATA COLLECTION, PHOTOGRAPHS OF EACH
RESTORATION SHALL BE TAKEN FROM THE PERMANENT PHOTO POINTS
ESTABLISHED DURING THE AS‐BUILT.
CONTINGENCY PLAN
SHOULD ANY COMPLIANCE MONITORING ASSESSMENT REVEAL THAT THE
PERFORMANCE STANDARDS FOR THE RESPECTIVE YEAR ARE NOT SATISFIED, THE
PERMITTEE SHALL WORK WITH THE CITY OF RENTON 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 RENTON BY
JANUARY 31 OF ANY YEAR WHEN DEFICIENCIES ARE DISCOVERED. UNLESS
OTHERWISE APPROVED BY THE CITY OF RENTON, ACTIONS SPECIFIED ON AN
APPROVED CONTINGENCY PLAN MUST BE COMPLETED WITHIN 60 DAYS. IF THE
FAILURE IS SUBSTANTIAL, THE CITY OF RENTON MAY EXTEND THE COMPLIANCE
MONITORING PERIOD FOR THE RESTORATION WORK.
MAINTENANCE PLAN
THIS SECTION PROVIDES A GENERAL OVERVIEW OF THE MAINTENANCE PROGRAM
NECESSARY TO ENSURE THE PERFORMANCE STANDARDS ESTABLISHED FOR THIS
PLAN ARE ACHIEVED.
NOXIOUS WEED CONTROL
FOLLOWING PLANT INSTALLATION AND AT REGULAR INTERVALS DURING THE
COMPLIANCE MONITORING PERIOD, NOXIOUS WEED CONTROL SHALL OCCUR ON A
SPOT TREATMENT BASIS WITHIN EACH ENHANCEMENT 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 KING COUNTY NOXIOUS WEED LIST.
NOXIOUS WEED CONTROL WORK SHALL CONSIST OF THE CUTTING AND REMOVAL
FROM THE SITE OF ALL NOXIOUS WEED SPECIES STEMS, CANES, RUNNERS, SHOOTS,
SEED PODS, FRUITING BODIES, AND LEAVES PER THE FOLLOWING METHODS:
1. HAND PULLING.
2. MANUALLY CUTTING USING MACHETES, LOPPERS, AND/OR CLIPPERS.
SPOT TREATMENT SHALL OCCUR MONTHLY AND/OR AT A GREATER FREQUENCY, IF
NECESSARY, TO CONTROL NOXIOUS WEED SPECIES TO A MAXIMUM OF TEN (10)
PERCENT OR LESS COVERAGE WITHIN THE RESTORATION AREA.
DURING ALL NOXIOUS WEED CONTROL WORK, EXISTING OR PLANTING NATIVE
VEGETATION SHALL BE PROTECTED FROM DAMAGE.
GENERAL MAINTENANCE
EACH ENHANCEMENT AREA SHALL BE MAINTAINED AT REGULAR INTERVALS
DURING THE COMPLIANCE MONITORING PERIOD TO PROMOTE THE SUCCESSFUL
ESTABLISHMENT AND VIGOROUS GROWTH OF THE INSTALLED PLANT STOCK.
GENERAL MAINTENANCE SHALL INCLUDE:
1. WEEDING THE ENHANCEMENT AREA.
2. RE‐APPLYING BARK MULCH TO MAINTAIN A 3" MINIMUM APPLIED
THICKNESS ‐ YEAR 1 ONLY.
3. THE PRUNING OF INSTALLED PLANTS TO REMOVE DEAD WOOD AND
PROMOTE VIGOROUS PLANT GROWTH AND PROPER FORM.
4. THE REPLACEMENT OF PLANTS THAT APPEAR TO BE IN DISTRESS AND/OR
DISEASED.
5. THE REMOVAL OF TRASH, LITTER, AND/OR OTHER NON‐DECOMPOSING
DEBRIS.
GENERAL MAINTENANCE WORK SHALL OCCUR MONTHLY DURING THE GROWING
SEASON AND/OR AT A FREQUENCY OTHERWISE NECESSARY TO ENSURE THE
SUCCESSFUL ESTABLISHMENT AND VIGOROUS GROWTH OF THE INSTALLED PLANTS
AND/OR THE CONTROL OF NOXIOUS WEEDS.
