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
