At the start of 2026, the Johnson County Post is looking ahead to some of the major development projects that we are keeping an eye on this year, including those that have already begun work or are anticipated to start in the next 12 months.
This story focuses on projects in Spring Hill.
Housing developments across town
Several housing developments are underway in Spring Hill, including:
- The Wiswell Farms neighborhood, located northeast of Kansas Highway 7 and 199th Street. The project is a Reinvestment Housing Incentive District, which allows the developers to recover infrastructure costs from property tax gains created by new development. Construction on the development started in 2024, and more than 100 homes have been sold since.
- The Hidden Hills neighborhood development is under construction along 207th Street, east of Woodland Road. The 115-lot development is in phase one of its construction, including 44 houses — several of which have already been sold. More homes will be move-in ready this spring.
- The Garrett Ranch neighborhood, which is under construction across from Spring Hill High School along Ridgeview Road. The project is in phase one of construction, which includes 50 single-family houses and two ponds. Eventually, the neighborhood will have 113 single-family homes and 255 townhomes.
- The Fox Hollow development at 207th Street and Ridgeview Road is set to include 352 homes. Construction started in late 2025. Design plans include a pool, covered pavilion and a playground.
199th Street roadway improvements
The city began work on a new 199th Street just north of the existing road, from Ridgeview Road to Renner Road. Work began in December on the 1.21 miles of new road, which will have new gutters, inlets, stormwater drains, curbs, sidewalks and the addition of a walking trail.
The project is a part of the city’s efforts to support growth, improve infrastructure and beautify the community.
New wastewater treatment plant
In late 2025, the city began the design phase on a new wastewater treatment facility. The current facility, located on Woodland Road between 223rd Street and 231st Street, is unable to meet the needs of the community as it continues to grow, city documents show.
The new facility will be located at the northwest corner of 239th Street and Woodland Road. Its capacity will start with 5 million gallons per day — compared to the current facility’s four-cell lagoons at a capacity of 0.13 million gallons per day. The new wastewater treatment plant will also have the capacity to expand to 30 million gallons per day as the city grows.
