Later Phase Eclipse Mill Project current USACE Wetland Delineation and regional supplement guidance (1987 manual and 2010 regional supplement). Information will also be collected as described in the Washington State Wetland Identification and Delineation Manual (Ecology publication #96-94) and consistent with the requirements of the CITY's Municipal Code Title 19.37 for critical areas. Data plots will also be collected in other areas that may have some wetland characteristics to verify presence/absence of wetlands. The wetland delineation flags and data plot flags will be marked on aerial photo maps and furnished for professional survey. Wetland rating forms will be completed using information gathered during the delineation visit. OHWM will be delineated following the guidelines identified in RCW 90.58 and WAC 173-22. Standard indicators outlined in Ecology's technical report, Determining the Ordinary High Water Mark for Shoreline Management Act Compliance in Washington State (Ecology 2016) will be used to delineate the OHWM. This task includes budget for two (2) CONSULTANT biologists to conduct OHWM surveys and wetland delineations over 2 days. This task also includes preparing an OHWM and Wetland Analysis Report to support permitting and critical areas compliance. The report will present the OHWM and wetland delineation results consistent with the previously mentioned guidance and manuals. The report will address the regulatory status of the wetlands according to the CITY and the Ecology rating system and include buffer width requirements and proposed buffer width modifications as applicable. Wetland rating and delineation forms will be prepared and attached to the report. The report will also include providing a list of recommended plants to be used for buffer enhancement to account for temporary and/or permanent wetland buffer impacts.
