As expected, Salt Lake County commissioners have approved a hike in greens fees at the three county-owned golf courses, matching recent increases at the six Salt Lake City public courses.

But in an attempt to compromise with angry golfers opposed to the hike, commissioners delayed a final decision on a proposed additional trail fee for golfers driving their own carts on county courses.County greens fees are now at $6 for nine holes and $12 for 18 holes, up from last year's $5 and $10, respectively. The price of cart rental went to $7 for nine holes and $14 for 18 holes, an increase from $6 and $12 rentals in 1988.

In addition, the cost of annual adult passes allowing unlimited weekday play at the Mick Riley, Meadowbrook and Mountain View courses went from $350 to $450, while the prices of junior and senior annual passes were doubled, from $175 to $350. Those compare to $500 and $400 respectively for city course annual passes.

Those protesting the hikes charged commissioners were making golf "a rich man's game," and urged them to "stop picking on the golfers."

The fee hikes are needed to avoid a projected $340,000 operating deficit for county golf courses by the end of 1989, said county Parks and Recreation director Glen Lu.
