Proponents of the Cedar River site and the west of the Piazza site for a downtown Renton library each will mount their final efforts to campaign for votes on Proposition 1 this weekend.

Citizens for the Cedar River Library will be campaigning up until 8 p.m. on election night, according to Stuart Avery, spokesperson for the group.

Through the weekend leading up to Aug. 7, members from the Cedar River camp will be placing signs, canvassing door to door and distributing literature.

Avery expects that there will be eight to 20 people involved in this effort, but said, “Like most campaigns there are also people in the community going about spreading the word completely on their own without direction from our committee.”

He was encouraged by the number of people who visited the group’s booth at Renton River Days last weekend and said he got a lot of positive responses and good questions from people.

Avery turns his concern now to just getting people to vote in the upcoming primary election.

With a lot of unknown or new candidates on the ballot he was concerned about Renton residents just not voting and missing the spending measures, including the library site selection vote.

“We’re focusing a lot of energy right now on making sure people send in their ballots,” Avery said. “We’re trying to educate people that they need to get these in.”

People for the Piazza Park Library also had a booth at Renton River Days. They also experienced a lot of curious people interested in the library site selection.

“We had some people that had already voted and a larger number of people still trying to get the facts,” said Laurie Beden, co-chair of the group. “There has been a lot of misinformation given out, much confusion on the issue itself and they were very glad to get a clearer picture of how this all came about and  the pros and cons to the two locations.”

People for the Piazza Park Library will also be out campaigning over the weekend and in the waning hours up until the election. Members plan to go “door bell with literature that will help people make the clear choice to choose to site the library west of the Piazza,” said Beden.

Whether voting for the Cedar River location or the west of the Piazza site, all ballots have to be postmarked by 8 p.m., Aug. 7.

It has been a tumultuous road for Renton libraries since the 2010 election that resulted in the annexation to the King County Library System.

In 2010, the vote was close with a difference of only 53 votes between annexation and staying separate from KCLS.

With the Cedar River grassroots effort essentially vocal and visible all year in their campaigning to preserve the Cedar River site, that location could be tough to beat in this election.

Meanwhile, the state Public Disclosure Commission still has nothing to report on complaints filed against KCLS. A number of Renton residents cried foul when the system sent out a letter early July explaining the different costs of the two locations.

The PDC is expected to decide whether to move forward with a formal investigation in another week or so.
