Friends of South Salt Lake's annexation bid likely have Aug. 15 on their calendars circled with a big, black marker.

That's the deadline for tax-levying entities to file a formal protest of the proposed annexation with the Salt Lake County Commission.Get past that date, and it's a good bet South Salt Lake will almost double in size this fall. The proposed annexation is roughly a 2.5-square-mile area from 700 East to the Jordan River and from 3300 South to 3900 South.

So far, dissenting voices have been silent.

"We've received nothing to say there would be a protest," said Assistant to the Mayor Cindie Poulson.

Any protest would have to be filed by a tax-levying entity like a school district or neighboring city. Private citizens cannot participate in the protest unless at least 25 percent of the landowners in the proposed annexation area band together to form a coalition.

But a private property owner can ask for a court injunction to block the annexation (like the Hermes Associates ongoing case against Midvale's 1998 annexation of the Union area). A judge would then have to decide if the property owner would be unduly harmed.

South Salt Lake received 1,130 petition signatures in favor of the annexation, Poulson said.

Public comment on the annexation will be welcome before the city council's Sept. 16 meeting to finalize the matter. If all goes as planned, the proposed unincorporated areas could be annexed into South Salt Lake as early as Oct. 1, Poulson said.

Expect to see some changes in the city if the annexation is approved.

"There will definitely be some increases in the police and fire departments," Poulson said, adding it's unlikely there will be any immediate city administrative expansion.

The city attorney is also reviewing how the proposed annexation may change the profile of the city council. Currently, there are three at-large city council members and four representing geographic districts.
