The Downtown River Plaza project plans will be unveiled 5:30 p.m. Tuesday at The Bottle House, 202 S. Walnut, Ottawa, organizers said. Refreshments begin at 5 p.m. with the program at 5:30 p.m.

Gov. Jeff Colyer is slated to attend the meeting. Colyer is in Ottawa to recognize the Flint Hills Nature Trail, First and Walnut streets, becoming a part of the State of Kansas, Wildlife, Parks, and Tourism system of trails.

Other state and local officials are also expected to be in attendance, organizers said.

“We are so excited to share the great progress toward the vision the community developed 18 months ago,” David Lee, co-chairman of the Onward Ottawa group, said. “And to have Kansas Gov. Jeff Colyer present as well is an honor.”

The project has been a community partnership initiative led by Onward Ottawa. Substantial progress has been made in the campaign to enhance the downtown, organizers said.

The plan for the project — located on Walnut Street between First and Second streets — is to turn the area into a place where people can gather for events and entertainment, as well as the possible site of a farmer’s market.

It would include putting landscape in the green space, building pergolas, improving the parking lot and adding a covering for a pavilion market area.

Ottawa was recently awarded an attraction grant of $92,715 to develop projects that will increase tourism in Kansas.

The project’s location at the crossroads of the Prairie Spirit Rail Trail and the Flint Hills Nature Trail was key in the project’s selection, organizers said.
