Summary and background of the Legislation:

The proposed Council Bill authorizes three separate agreements between the City and the Washington State Department of Transportation (“WSDOT”) that will allow for City participation in the SR 99 Bored Tunnel Project. The Project replaces SR 99 from South Royal Brougham Street to Roy Street and consists of designing and constructing a four-lane tunnel from South King Street to Thomas Street, north and south tunnel portals and access streets, re-establishment of the City street grid in the vicinity of the portals, and associated utility relocations. The agreements authorize preliminary work on the Project. Further work on the Project may not be authorized until after WSDOT and the City Council have reviewed the final environmental impact statement and given notice to proceed.

The Project consists of the following features:

Tunnel:

A four-lane tunnel under the City from a south portal in the vicinity of Dearborn Street and Alaskan Way to a north portal in the vicinity of 6^th Avenue North and Harrison Street.
PROJECT work will include:

Approximately two miles of cut-and-cover and bored tunnel providing two travel lanes in each direction.
Tunnel portal structures and the shoring walls and excavation associated with portal construction.
Tunnel operations buildings at both the north and south portals to house tunnel egress, tunnel ventilation systems, and fire and life safety systems and controls.
Tunnel operations, intelligent transportation, and fire and life safety systems.
Monitoring of, and mitigation, for tunnel-induced Deformation, such as protecting utilities, and preparing structures for predicted tunnel-induced Deformation through engineered measures such as grouting and structural retrofit.
Repair of public and private property that may be damaged as a result of construction.

North Tunnel Access and Reconnection of the Surface Street Grid:

· SR 99 roadway and roadway structures connecting the tunnel to existing SR 99 in the vicinity of Aurora Avenue at Roy Street, associated on and off ramps, and City right of way in the vicinity of the north tunnel portal.

o Storm drains and other utilities in the new City street right-of way.

South Tunnel Access and Reconnection of the Surface Street Grid:

· Roadway and roadway structures connecting the tunnel south portal to SR 99 lanes being constructed as part of the Holgate to King Project in the vicinity of South Royal Brougham Way and improvements to City street right-of-way in the vicinity of the south tunnel portal.

· PROJECT work will include:

o Removal of the south-end SR 99 temporary roadway detour built as part of Holgate to King Project.

o Maintenance of utility service.

Utility Work:

Removal and replacement of existing City electrical, communications, water, drainage and wastewater facilities and other privately owned utilities that directly conflict with the north and south tunnel portals and tunnel portal excavations .
Utility services necessary for the operation of the tunnel and tunnel operations buildings
New Utility improvements.

The three agreements authorized by this Bill govern different elements of the relationship between the City and WSDOT as follows:

· Property, Environmental Remediation, Design Review, Permitting and Construction Coordination (to be signed by the Seattle Department of Transportation, “SDOT”).

· Seattle City Light Facilities Work (to be signed by Seattle City Light, “SCL”).

· Seattle Public Utilities Facilities Work (to be signed by Seattle Public Utilities, “SPU”).

Under the agreements, WSDOT is responsible for providing necessary funding for all project costs without reimbursement from the City of Seattle, with the exception of the relocation of SPU and SCL utilities that conflict with WSDOT’s North and South Portal construction. The City is responsible for paying for any betterments.
