The Lid I-5 team will be among a number of organizations attending the Washington State Convention Center’s December open house, making its case for adding a feasibility study to the public benefits package the WSCC needs to provide to construct its addition.

The WSCC Addition will be located between Ninth and Boren avenues and from Howell to Pine streets, assuming Olive Way space as well as the end of Terry Avenue. Terry Avenue is one of three vacations that are being asked for by project managers with the southern end of the street intended to be underground to keep the street open.

The convention center not only has to cover costs associated with these vacations, it has to propose a public benefits package.

Shortly after WSCC announced plans for its addition, which would double the convention center’s footprint, the Lid I-5 campaign was formed.

While placing a lid over I-5 likely wouldn’t occur until the interstate is slated for renovations, the Lid I-5 group is advocating for a feasibility study to determine how a lid could eventually be implemented.

Lid I-5 representative Scott Bonjukian told the Pike/Pine Urban Neighborhood Council last week that study is estimated to cost between $500,000 and $1 million.

Many other organizations will attend the WSCC Addition open house 5-7 p.m. Wednesday, Dec. 7, in Room 2AB of the WSCC, 705 Pike St. More information is at www.wsccaddition.com/community/public-benefits

While affordable housing is not recognized as an allowable action in the public benefits package, Capitol Hill Housing and other affordable housing organizations will also attend the open house.

Lid I-5 members will be at the Broadway Farmers Market 11 a.m. to 3 p.m. Sunday, Dec. 3, to discuss their efforts. The group also recently launched a new website. Find more information at www.lidi5.com

Lid I-5 is sponsored by the Seattle Parks Foundation. Its partners include Freeway Park Association, First Hill Improvement Association, Capitol Hill Housing, Central Seattle Greenways, Melrose Promenade and state Rep. Brady Walkinshaw.
