A skate plaza and a play area could be built alongside one of Lincoln's best-known historic landmarks.
If approved, more than £350,000 could be spent on building the attractions next to the Grade II listed Grandstand in Carholme Road.
The Kiln skate facility, which is planned for land on the north west side of the building, will include a memorial to city skateboarder Karl Cody. And the play area, on the south east side, could be themed around its location on the West Common and next to a former Roman fort and race course.
Skateboarders, roller bladers and BMX and scooter riders will all be able to use The Kiln, which will be between 800 and 1,100sq metres.
The facility was named after Roman remains that sit below the proposed site.Both ideas have been developed by the City of Lincoln Council.
Antony Angus, recreational services team leader at the authority, said: "I'm really confident it's going to be popular and really well received.
"The design is fantastic and we're sure it will hit the mark. With the nearby tennis courts, common, golf club and hopefully a skate plaza and play area, the area will be a magnet for families."
The £200,000 plaza designs feature low ramps and grind rails to allow for more ground-based tricks, catering for a wider range of abilities than large half pipes.
Designs are yet to be drawn up for the play area, but £152,000 is available thanks to a Section 106 agreement signed when houses were built on the former e2v site in Carholme Road. The 5,000sq metre play area will include areas for children aged up to 19.
Features that can be used by people with disabilities will be included in both facilities.
The concepts were presented to the Commons Advisory Panel on Wednesday, October 10.
Further public consultations will take place before planning applications are submitted.
John Shipton, 63, who lives off Long Leys Road and is a member of the Commons Advisory Panel, said: "The concept is brilliant and I think the panel would be in support of it as long as security measures are in place. Other skate parks have attracted graffiti and we don't want that turning to vandalism and spreading to the Grandstand and play area."
The Kiln will be funded by grants, City of Lincoln Council funds, the authority's partners and money raised by Karl Cody's friends.
Cash was collected to build a facility in memory of the 22-year-old after he was killed in a 2002 moped crash in Burton Road. Skater Karl Barkworth, 28, who owns the Grindhaus skate store in St Martins Lane, is set to give the council 750-signature petition pushing for a new facility.
He said: "It's exactly where we were hoping a park could be put. It's what we have been wanting for 15 years. It's all about respect in the skate community, so to do it as a memorial is fantastic."
A previous proposal for a skate facility at Yarborough Leisure Centre was scrapped after it was decided the plot was too small.
