species shall not be criteria for success. By the end of the third growing season, the percent of survival shall be 80% for all areas. If an azea contains more than 20% exotic species (non-native species) then the mitigation shall not be considered successful for that area. CONTiNGENCY PLAN If during any of the inspections, 20% of the plants are severely stressed, or it appears 20%v may not survive, additional plantings of the same species may be added to the planting area. If this situation persists into the next inspecdon, a meeting with Snohomish County, the consulting wetland biologist, and the property owner will be scheduled to decide upon contin;ency plans. Elements of the contingency plan may include, but will not be limited to: more ageressive weed control, mulchin�, replanting with larger plant material, different species, fertilization, soil amendments, and/or irri�ation. �'S��L�ITENA,�CE Prior to the initiation of this plan, a signed three-year maintenance agreement between the property owner and a landscape technician shall be made available to Snohomish County. Planting areas shall be maintained in the sprin� and summer of each year by the landscape technician for the three-year monitoring period. Maintenance shall include, but not be limited to the removal of competing grasses and non-native vegetation, and irrigation of planted matcrials as necessary. PERFOR�I�INCE BONDING A performance bond or assignment of funds will be provided to Snohomish County for the period of three years from the completion of the miti�ation project in the amount of 120% of the estimated cost for plant material, labor, monitoring, and maintenance. This bond shall be released at the end of three years, upon a"successful deternunation" for all portions of this restoration/enhancement project. The definitions of success shall be as described in the PROJECT MONI'I'ORING in this plan. NU�iBER OF l GALLON PLANTS 129 14 . � �°��o
