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 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 AS WELL AS ANY DEVIATIONS FROM THE APPROVED VERSION OF THIS PLAN. IN ADDITION, THE AS -BUILT SHALL CONTAIN BASELINE MONITORING DATA AND PHOTOGRAPHS OF EACH PLANTING AREA PER THE FOLLOWING: • BASELINE VEGETATION SAMPLING SHALL BE COMPLETED WITHIN EACH PLANTING AREA.

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 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.
