Fees at Fairfax County parks, recreation centers and golf courses will rise April 1 to cover a budget shortfall, the Park Authority board has decided.

The $1 increase in greens fees at county-run golf courses and the rise in daily, monthly and yearly admission charges at the eight recreation centers will bring in the most money, park officials said. The greens fee increase, for example, will provide the county with an anticipated $278,000 more a year.

Rec center fees will jump 50 cents a day, from $7.50 to $8. Monthly pass charges will increase $5 for individuals and $8 for families. A yearly pass will rise $36.50 for individuals and $68 for families. Discounts will still apply for county residents. The adjusted rec center fees -- the first increases in three years -- are expected to bring in more than $163,000 in additional revenue, park officials said.

Lower-than-expected revenue from fees prompted the increases. Park officials have speculated that the October sniper attacks and the snowier than usual winter kept people away from the parks. The Park Authority depends on fees for half its revenue, with the rest coming from the county government.

"This is a routine process that happens yearly," Park Authority spokeswoman Judy Pedersen said of the adjustments. She said the authority is facing higher costs and a long list of needed repairs.

Among other fees that are new or will increase: reserving a picnic area at Lake Fairfax, using gym space at the Audrey Moore and Lee District RECenters, launching a boat at Lake Fairfax and Burke Lake, renting a campsite during peak season at Lake Fairfax, riding horses at the Equestrian Center at Frying Pan Park, renting a county historic property for an event and skating at the new Wakefield Skate Park.
