It's a multi-million dollar project that will change the skyline of downtown Sioux Falls. The Uptown at Falls Park development was unveiled in August 2006, but three years later, the project is hitting some bumps in the redevelopment road.

For the last two months, the Wild Whoopie Bakery has been whipping up confections.

"Love this space, love the old buildings. It just seemed to fit," Wild Whoopie Bakery owner Tammy Wiertzema said.

But the bakery isn't in downtown Sioux Falls; it's Uptown.

"It's teaching people the Uptown part, you know at fourth and Main," Wiertzema said.

The Wild Whoopie Bakery is one of the newest members of the Uptown at Falls Park development, a $100 million project that involves a partnership between four Sioux Falls development companies, land contracts with the city and a ten-year plan.

"We've been making steady progress. As you can see, we have two buildings that are completed and done," Jennifer Fleming with the Uptown project said.

The Wild Whoopie Bakery is in one of two old buildings Uptown developers restored and refurbished as part of one of the first phases of the project. Developers were hoping to build two tall buildings, known as the Arches, near the completed buildings next, but a few snags are holding up those plans.

"Development is an on-going process and we are working with the city right now on some environmental issues on the land behind me for the Arches," Fleming said.

The land where the Arches are proposed to be built is still owned by the City of Sioux Falls, and the land can't be transferred to the developers of Uptown until contaminants are taken out of the soil. The bare ground used to be home to an old salvage yard and railroad grade, and that's why the soil is polluted.

"The next step is really figuring out where they go. Where those contaminated soils go in a way that's environmentally friendly," Fleming said.

Developers are working with local and state officials to resolve those issues, but building the Arches is also being held up by the ailing economy.

"We did have two tenants who decided to hold off a little bit due to the economy," Fleming said.

And because developers have run into a few challenges with the Uptown project, instead of building the Arches part of the development next, they are going to proceed with a different, and smaller phase, of the project until market conditions improve.

"They're looking at a smaller scale project on 3rd Avenue, and I think that will be the next bite that we will take into the project, and we'll kind of see where we go from there," Fleming said.

The 3rd Avenue building will be brand new and have 20,000 square feet of commercial space and residential loft apartments. While it wasn't a move that was in the plans, developers say it will keep the project moving forward.

"We know when we started this project it was going to be an on-going, lengthy process, ten plus years. And it's always driven by the market, so we're going to let the market and our partners kind of help us make the momentum and forward motion on this project," Fleming said.

Stores like the Wild Whoopie Bakery are starting to see that momentum pick up.

"People just love it when they come here and realize that there's this whole little town going on," Wiertzema said.

"We're all committed to this. We've all got dollars invested in this, and skin in the game so to speak, so we're committed to do Uptown and do it in a way that makes sense," Fleming said.

Even if it means taking a detour in the drive to make Uptown a reality.

Developers say both of the completed buildings are full, except for a few loft apartments that are still available to rent.
