Oak Park

Stormwater lines in a Lenexa neighborhood had not been upgraded since the 1970’s. Some had rusted through and needed to be replaced, so they could perform optimally. The city wanted to add a new system that could handle the increase in capacity needed and keep residents’ homes from flooding.

Our team was selected to design the project and oversee the construction. For the first phase, we reviewed storm sewer CCTV inspections to determine the condition of the existing pipes and discover which pipes could be lined versus which needed full replacement. We also performed a preliminary hydraulic analysis and distributed flooding questionnaires to identify any issues that needed to be resolved.

For the second phase of the project, our team began by surveying the site. Drawing on our preliminary study and the survey results, we developed the stormwater design. The project also included new sidewalks, curb, gutter, lighting relocation, and utility coordination.

Some of the pipe was located in backyards, which meant extensive coordination with local residents and restoring properties to their previous conditions. By having engineering and construction observation services in-house, we could quickly resolve any issues that arose in the field. It also meant our construction engineering group had a clear understanding of the scope and the city’s goals before they stepped onto the site.
