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 RESTORATION 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 RESTORATION AREA. FOLLOWING PLANT INSTALLATION, PERMANENT COMPLIANCE MONITORING PLOTS OR TRANSECTS SHALL BE ESTABLISHED TO DOCUMENT BASELINE VEGETATION CHARACTERISTICS WITHIN EACH RESTORATION 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 RESTORATION 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 RESTORATION AREA FOR PURPOSES OF EVALUATING THE CURRENT YEAR'S PERFORMANCE STANDARDS. AT THE TIME OF EACH MONITORING ASSESSMENT, THE FOLLOWING INFORMATION SHALL BE COLLECTED Wi T HIN EACH; RESTORATION 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 RESTORATION AREA.

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 RESTORATIOV AREA SHALL BE MAINTAINED AT REGULAR INTERVALS DURING THE COMPLIANCE MONITORING PERIOD TO PROMOTE THE SUCCESSFUL ESTABLISHMENT A`qD VIGOROUS GROWTH OF THE INSTALLED PLANT STOCK.
