S April 10, 2020 Page 7 Established performance standards for the Project will be compared to the monitoring results to judge and document the success of the Project. If there are significant problems with achieving the performance standards,the applicant shall develop a corrective action plan. Corrective actions may include, but are not limited to, regrading or stabilizing areas of erosion; plant installations; and plant substitutions of type, size,quantity, and location. On-site maintenance and remedial action will be implemented immediately upon completion of the monitoring event (unless otherwise specifically indicated in the following list).Typical maintenance activities will include, but are not limited to, the following: • During Years 1 and 2, replace all dead plant material to achieve a minimum of 90%survival. • Replace dead plants with the same species or a substitute species that meets the goals and objectives of the mitigation plan. • Replant area after reason for failure has been identified and corrected (e.g., moisture regime, poor plant stock,disease,shade/sun conditions,or wildlife damage). • Remove trash and other debris. • Prune woody plants as necessary to meet the mitigation plan's goals and objectives (e.g.,thinning and removing dead or diseased portions of trees and shrubs). • Any major changes to topography due to severe flood events will be documented, and a corrective action will be discussed with USACE and the City of Everett. Corrective actions will range from recontouring to re-establish grade to a contingency that may include a change in plans to adaptively manage flooding. Contingency Plans Contingency plans describe what actions can be taken to correct site deficiencies.Specific contingency actions relative to interim performance standards are identified in Table 2. Goals, objectives,and performance standards create a baseline that is used to measure whether the site is performing as proposed and to determine whether a contingency plan is necessary.All contingencies cannot be anticipated.Any contingency plan will be flexible so that modifications can be made if portions of the final design do not produce the desired results. Problems or potential problems will be evaluated by a qualified wetland ecologist,a restoration engineer,and the applicant.Specific contingency actions will be developed,agreed to by consensus with USACE and the City of Everett, and implemented based on all scientifically and economically feasible recommendations. Contingency actions include, but are not limited to,the following: • Plant species alteration • Recontouring The applicant will implement contingency plans on an as-needed basis.Contingency plans will be developed for review and approval by USACE and the City of Everett, as appropriate. In addition, implemented contingency plans and their effects will be described in the next monitoring report.
