National Environmental Policy Act (NEPA)
NEPA is a law that requires federal decision-makers to consider how their actions, such as the use of federal funds, land or permits, may effect the environment. NEPA also requires that decisions include public input, through scoping and review of NEPA documents.
State Environmental Policy Act (SEPA)
Similar to NEPA, SEPA is a state policy that requires state and local agencies to consider the likely environmental consequences of governmental decisions. These decisions may be related to issuing permits for private projects, constructing public facilities, or adopting regulations, policies or plans.
Environmental Assessment (EA)
In accordance with NEPA, an EA is used to analyze the environmental effects of a proposed activity when the significance of those effects is uncertain. Depending on the EA findings, an environmental impact statement (EIS) or a Finding of No Significant Impact (FONSI) will subsequently be prepared.
Determination of NonSignificance (DNS)
In accordance with SEPA, a DNS is used to document a proposal that is not likely to have significant adverse environmental effects.
Finding of No Significant Impact (FONSI)
In accordance with NEPA, a Finding of No Significant Impact (FONSI) is prepared when no significant impacts are determined during the EA process.

Construction
Design-Bid-Build Method
Design-bid-build is the traditional construction method WSDOT uses for most of its transportation projects. In design-bid-build, the project is designed to 100 percent and then advertised; the contract is awarded to the lowest bidder.
Design-Build Method
In a design-build construction method, WSDOT awards a contract to a construction/design team based on cost and technical qualifications. The selected contractor is responsible for completing the design and constructing the project.
Design-Builder
The firm, partnership, joint venture or organization that contracts with the Washington State Department of Transportation to provide design, construction and quality control services for the project.
Proposers
Firms, partnerships, joint venture and organizations furnishing proposals in response to a WSDOT request.
Request for Qualifications (RFQ)
The formal request by WSDOT of design-build proposer qualifications consisting of, among other things, experience, capabilities and past performance.
Request for Proposal (RFP)
An RFP is a formal request to Design-Builders to submit a construction proposal and price.

General
Alaskan Way Viaduct and Seawall Replacement Program
The Alaskan Way Viaduct and Seawall Replacement Program is composed of the Moving Forward projects, located in the north and south ends of the viaduct, and the central waterfront project.
The Moving Forward projects will repair or replace about half of the seismically vulnerable viaduct. They are necessary to improve public safety and keep traffic moving no matter what replaces the viaduct's central waterfront section. The Moving Forward projects are:
The central waterfront project will be decided through a collaborative process managed by the State of Washington, King County, and the City of Seattle.
Channelization Plan
Design drawings showing lane configurations and traffic movements.
Memorandum of Agreement
A Memorandum of Agreement (MOA) is a document written between parties to cooperatively work together on an agreed upon project or meet an agreed upon objective. The purpose of an MOA is to have a written understanding of the agreement between parties.
