News Summary
Shawnee has announced a temporary closure of Monticello Road at 60th Street to conduct emergency stormwater pipe repairs from August 4 to August 8. The repairs are necessary due to the deterioration of underground infrastructure, with concerns over sinkholes near Mill Valley High School. A large stormwater pipe is being replaced with reinforced concrete to prevent future incidents. The city has allocated around $2 million for this and ongoing infrastructure improvements, ensuring safety for residents and students during the upcoming school year.
Shawnee Announces Temporary Closure of Monticello Road for Stormwater Repairs
The city of Shawnee will temporarily close a section of Monticello Road at 60th Street from August 4 to August 8 to conduct emergency stormwater pipe repairs. The move aims to address urgent infrastructure issues before a more extensive, full closure planned for September.
Immediate Repairs Due to Sinkhole Risks and System Deterioration
The emergency repair efforts are prompted by the presence of roadway plates covering damage near Mill Valley High School, a sign of ongoing issues with underground stormwater infrastructure. City officials have emphasized that the repairs are critical and cannot be postponed, citing concerns that deteriorating pipes and recent heavy rainfall increase the risk of additional sinkholes forming.
A sinkhole approximately 10 feet deep has already been reported on the high school campus, caused by a failed underground stormwater pipe. This pipe, a large corrugated metal arch installed in 1999, has reached the end of its 20-30 year lifespan and is deteriorating rapidly.
Background on the Damage and Infrastructure Challenges
The city’s stormwater system includes numerous pipes, many composed of corrugated metal, which are prone to corrosion and failure over time. Currently, about half of Shawnee’s stormwater pipes are of this type. The failed pipe near Mill Valley High School specifically measures 69 inches by 96 inches.
The city has identified that these aging pipes are responsible for ongoing issues including the recent sinkhole and surface damage to the roadway. To prevent complete failure and ensure safety, Shawnee plans to replace these with reinforced concrete pipes, expected to last up to 100 years—significantly longer than the existing infrastructure.
Funding and Project Details
The repairs are financed through a bond issue approved by local voters in 2023 via the Parks and Pipes sales tax. The city council approved a budget of roughly $2 million for the project, which covers both the immediate emergency repairs and planned replacements.
The project involves installing a reinforced concrete box and applying a geopolymer lining to the pipes, which alone costs approximately $995,000. These materials are chosen for their durability and longevity, aiming to reinforce the stormwater system against future failures.
Timeline and Impact on Community
The emergency repairs are set to be completed within approximately four months, with the goal of finishing before the start of the upcoming school year. The work will include temporary roadway closures, with detours along Shawnee Mission Parkway, Woodland Drive, and Johnson Drive, clearly marked for motorists.
Neighbors near Mill Valley High School — which is located in the De Soto School District — have expressed hope that repairs will proceed swiftly to ensure safe access for students and staff as classes begin soon. Fortunately, Mill Valley High School operations are expected to continue unaffected during the repair process.
Additional Information and Safety Measures
The city’s Public Works Department oversees the project, which is designed not only to repair the current damage but also to prevent further deterioration of Monticello Road. The upgrades will help avoid a major emergency closure in the future.
No injuries have been reported due to the sinkhole or related issues, and the school district has expressed satisfaction with the city’s repair plans.
Future Infrastructure Improvements
This emergency project is part of a broader initiative to improve Shawnee’s stormwater infrastructure. The city plans to gradually replace older corrugated metal pipes with more durable options as part of ongoing maintenance efforts, reducing the risk of similar incidents moving forward.
City officials underscore that the repairs are vital to maintaining safe roadway conditions, protecting public safety, and extending the lifespan of urban infrastructure. With work scheduled to commence immediately upon approval, residents and commuters are advised to stay informed about detours and timeline updates.
