Exhibit A LL FY Deliverables 1. Draft APE Map (electronic file) 2. Draft and Final Cultural Resources Assessment Report with HPI forms (electronic files) 3. Geotechnical Boring Inadvertent Discovery Plan 4. Construction Inadvertent Discovery Plan (included as an appendix to the Draft and Final Cultural Resources Assessment Report) Subtask 702 — Natural Resources Field Assessment and Documentation Objective Conduct site visits to delineate and map Critical Areas and prepare natural resource documentation that characterizes Critical Areas in the project corridor and that describes anticipated project impacts pursuant to regulatory requirements. Consultant Services 1. Complete a desktop assessment of the project corridor, using available GIS resources, to determine the likelihood of a wetland, stream, or lake on-site or within 300 feet of the project corridor. 2. Desktop assessment will be followed by a site investigation to walk the project corridor in areas where the desktop assessment indicated the possibility of encountering aquatic critical areas and to document critical area presence and absence. Wetlands or streams found along the project corridor will be delineated and mapped and data forms completed to document findings. 3. Delineate and map the HTL and the OHWM, and characterize the shoreline of the Snohomish River. The HTL serves as the landward extent of jurisdiction over the project by the USACE and is not necessarily coincident with the OHWM. The OHWM determines jurisdiction over the project by the State Department of Fish and Wildlife and determines the limits of Shoreline Jurisdiction. 4. Prepare a Draft and Final Critical Area Delineation Report (compliant with Everett Municipal Code 19.37.070 and 19.37.073). This document provides information on the presence of delineated streams, wetlands, the shoreline, and their buffers, based on HDR's background data review and field delineations; discusses the proposed mitigation sequencing and project impacts to wetlands, shorelands, and Fish and Wildlife Habitat Conservation Areas; and discusses applicable City regulations and utility exemptions. 5. Produce a draft Project Mapbook that will be used to support the natural resources documentation and will show (as appropriate) critical areas and buffers, delineated wetland and stream features, parcel boundaries, jurisdictional boundaries, topographic contours, and other available data. The maps will also show project information including the location of conveyance improvements, the regional stormwater treatment facility, and the proposed stormwater outfall. 6. Prepare a Biological Assessment (BA) to evaluate the proposed project in terms of its potential impacts to any species listed or proposed for listing as threatened or endangered under Section 7 of the Endangered Species Act.
