Knowing when to replace aging corrugated metal pipe (CMP) can be an involved process that requires commitment and resources from cities managing infrastructure. There are obvious signs of CMP failure that are easier to identify once they occur, such as crushed, bowed, or deformed pipes or a rusted pipe bottom. But, staying on top of […]

Johnson County has been working on a strategic planning effort to update their Stormwater Management Program (SMP). Since 1990, the SMP has been very successful in helping Johnson County communities address local street and structure flooding issues. However, many larger flooding issues still remain, due to their high cost and the challenges that come with […]

wet detention basins

The complexity and benefit of stormwater basins varies to meet the specific design intent of a project. If reducing peak flow rates to existing conditions is the priority, a dry detention basin should be considered. If downstream channel stability is a concern, an extended detention basin should be considered. Or, if improved water quality is […]

section 203 preliminary feasibility assessment

The Prairie Band Potawatomi Nation (PBPN) has identified problems in creeks on their Reservation. These issues include streambank erosion, sedimentation, and poor water quality, and they impact wildlife habitat within and adjacent to these creeks. Under the authority of the Tribal Partnership Program, the tribe sought to partner with the United States Army Corps of Engineers […]

Although it’s been popular in other parts of the country for decades, using a watershed approach to stormwater management is a relatively new method in the Midwest. A watershed is simply an area bounded by an elevation divide that drains to a particular waterbody. Because watershed boundaries rarely follow jurisdictional lines, a watershed approach to […]

Harlan Lake Ecosystem Restoration

Maintaining or restoring healthy habitat for native plant and animal species is no easy feat. This task is something we tackle through our ecosystem restoration work. Our experience includes developing shoreline stabilization measures to reduce and direct in-lake sediment deposition currently impacting reservoirs in the region. These projects are expensive, and the key is to […]

sedimentation in Kansas reservoirs

Reservoirs built by the Federal Government in Kansas in the 1950’s and 60’s were designed to fill with sediment. However, many are filling faster than expected, due to excessive streambank erosion, lake shore erosion, and agricultural runoff. This sedimentation reduces in-lake storage, fills in shallow lake coves, and covers the lake bottom in a layer […]
