To build a citywide streetcar network, Seattle is considering four possible new lines connecting neighborhoods to downtown.

After completion of the 1.3-mile streetcar line in South Lake Union last year, city officials now envision a streetcar system similar to the one in place before 1941.

"If the community is ready to make the commitment, they're buildable," said Grace Crunican, Seattle transportation director. "You can put it in place, start building and add to it as financing comes in."

Transportation officials will present their ideas today to the City Council.

The four proposed lines would run between Queen Anne and the Central Area, between Ballard and Fremont, between South Lake Union and the University District, and between Capitol Hill and First Hill.

Mayor Greg Nickels and the City Council have not yet committed funding to build new lines.

The South Lake Union streetcar opened in December after a year and a half of construction. Property owners along the route are paying half of the $52 million cost.
