Figure 4 portrays the timeline associated with the implementafion of the Plan. 3.5.1 Detailed Monitoring Over a five yeaz period following wetland construction, vegetation, water levels and wildlife use will be monitored and provide data to judge degree to which individual components of the overall miugation plan meet the desired requirements. DocumeQtauon of the success of proposed planfings, establislunent of"volunteer" plants and observations of siltaaon will be provided by the monitoring progracn, allowing City of Everett staff and the monitoring biologist to determine the need for implementing conangency actions. A fixed baseline (Figure 4) will be established along the easterly margin of the created wetland on the northeast side of Wetland E. The ends of the baseline and angle point will be established by installa6on of steel rebaz encased in plastic pipe. At each of two random locauons along the baseline, a monitoring transect Gne will be extended at a proscribed angle to the baseline and extend across the created scrub-shrub and emergent wetland zones, through the e�cisting wetland and to the creared zone(s) on the opposite sides of the mitigation azea, if applicable. Along each of the rivo monitoring transects, two randomized permanent data plot locauons in each of the wetland zones and one reference location in the existing weUand will be established by installadon of sreel rebar encrsed in plas6c pipe. Wetland Uegetation. Data collection will be performed at each created and enhanced weUand data plot location, estimaung cover class percent cover, where applicable for tree, shrub and herb layers. At each of these locations, the following additional information will be taker.: • Survival/Mortality counts - noting signs of stress (presence of dead material or disease); � As detetmined at the end of[he annual moniroring event Z Tree and sluub cover only .
