ENVIRONMENTAL CHECKLIST for the Fishermen’s Terminal Gateway, West Wall, and Seattle Ship Supply Improvement Project Port of Seattle SEPA File # 17-07 prepared for Port of Seattle September 8, 2017 EA Engineering, Science, and Technology, Inc., PBC Cultural Resource Consultants Transpo Group PREFACE The purpose of this Environmental Checklist is to identify and evaluate probable environmental impacts that could result from the Fishermen’s Terminal Gateway, West Wall, and Seattle Ship Supply Improvement Project and to identify measures to mitigate those impacts. “In 2015, the Port of Seattle initiated a planning process concerned with the upland assets of the Fishermen’s Terminal property. The objective was to determine how the uplands can best support the homeporting activity of the commercial fishing fleet. The evolving needs of the fleet were considered along with the aging structures on the uplands. A comprehensive stakeholder outreach program was part of the planning process. The Fishermen’s Terminal Gateway, West Wall, and Seattle Ship Supply Improvement Project would involve redevelopment of the Gateway site in up to 86,250 sq. ft. of marine sales and services, with accessory office and warehouse uses, the West Wall site in up to 48,200 sq. ft. of maritime flex-industrial and 33,000 sq. ft. of exterior open storage and the Seattle Ship Supply in up to 26,000 sq. ft. of workforce and maritime incubator uses. 1 The State Environmental Policy Act (SEPA) requires that all governmental agencies consider the environmental impacts of a proposal before the proposal is decided upon. This Environmental Checklist has been prepared in compliance with the SEPA Rules, effective April 4, 1984, as amended (Chapter 197-11), Washington Administrative Code; and Port of Seattle SEPA Resolution No. 3650. This document is intended to serve as SEPA review for site preparation work, building construction and operation of the proposed development comprising the Fishermen’s Terminal Gateway, West Wall, and Seattle Ship Supply Improvement Project. Analysis associated with the proposed project contained in this Environmental Checklist is based on plans for the project, which are on-file with the Port of Seattle. While not construction-level in detail, the schematic plans accurately represent the eventual size, location and configuration of the proposed structures and are considered adequate for analysis and disclosure of environmental impacts. This Environmental Checklist is organized into three major sections. Section A of the Checklist (starting on page 1) provides background information concerning the Proposed Action (e.g., purpose, proponent/contact person, project description, project location, etc.). Section B (beginning on page 9) contains the analysis of environmental impacts that could result from implementation of the proposed project, based on review of major environmental parameters. This section also identifies possible mitigation measures. Section C (page 43) contains the signature of the proponent, confirming the completeness of this Environmental Checklist. Relevant project analyses that served as a basis for this Environmental Checklist include: the Greenhouse Gas Emissions Worksheet (EA, 2017), Historic/Cultural Resources Analysis (CRC, 2017); and Transportation Impact Analysis (Transpo Group, 2017). These reports are on-file at the Port of Seattle, and are included as appendices to this SEPA Checklist. 1 Chapter 43.21C. RCW Table of Contents Page A.

The purpose of this checklist is to provide information to help identify impacts from the proposal (and to reduce or avoid impacts, if possible) and to help the Port of Seattle to make a SEPA threshold determination.
