Peters said he will ask the city of Tulsa to assume funding responsibility for county projects that primarily benefit the city. That includes $35 million for Expo Square, about $12 million for LaFortune, Chandler and O’Brien parks, and $18 million for roads and bridges.

County officials say the improvements to Expo Square are necessary to retain major attractions such as the U.S. Arabian and Half-Arabian Horse Show. Peters said that event brings $26 million to the area each year, and most of its benefits are to the city of Tulsa.

If the city agrees to the county’s proposal, Peters said, the county will offer a roughly $75 million package, costing 0.05 percent over 13 years, for projects outside the city of Tulsa.

That may be a big “if.” The proposal comes as the city is finalizing its tax package, which would include shifting about 40 percent of the 0.6 percent “Vision” tax rate from a temporary capital improvements levy to a permanent public safety tax to support police and fire.

There is some concern, however, that separate proposals that combine to lift the total tax rate even a small amount could cause both to fail.
