Scores of popular events in Perth and Kinross are likely to be hit by new charges.
Councillors are expected to approve proposals to introduce standard rates for hiring parks and open spaces.
Previously, all non-commercial events were allowed to use facilities free of charge, but this could change under these latest plans.
A report to go before members of Perth and Kinross Council’s environment committee revealed that approximately 86% of events held on parks and green spaces qualify for free hire.
From next month, however, they could be expected to pay a three-figure sum.
Smaller events, which have fewer than 100 people attending, will still be allowed to use the land free of charge, but anything larger will attract a fee of between £50 and £100.
In his report, waste services and community greenspace manager Bruce Reekie outlined the reasons for the new charging structure.
He said: “It is proposed to amend the charges for events on council parks and open space.
“It is also proposed to charge (at a lower rate) for charity/not-for-profit activities and also to confirm that charges apply for the period the site is being used, including days taken to set up and take down events.
“It is recognised that any revised proposed charges should not be set too high as this may discourage small community organisations and individuals from using our parks and green spaces for events. Nonetheless, commercial and non-commercial events do take a considerable amount of organisation from a council perspective.
“As an example, events can require a high amount of administration time, attendance at meetings, assistance with alternative options, and dealing with reinstatement of land once the event has taken place.”
Organisers of commercial events, including fun fairs, circuses and balloon flights, will have to pay £305 to use the Lesser South Inch, North Inch and South Inch in Perth, while all other parks and open spaces across Perth and Kinross will carry charges of £125 per day.
In addition, there will be a minimum refundable deposit of £500, which will be retained if there are incidences of fly-posting.
Changes have also been made to fees for football pitch bookings.
In place of the 28 different fee rates for football pitches managed by the Community Greenspace team, adult and junior teams will pay a flat rate per season or per game for either 11-a-side or 7-a-side games, with prices from £23 for an adult seven-a-side game in Perth, rising to £39.50 for 11-a-side teams.
Environment convener Alan Grant said: “The changes being proposed in this report are intended to provide consistency in our arrangements and ensure that the vibrant green space we have locally can be most effectively used.”
