System Management
Failed stormwater pipes can lead to large failures like sinkholes
A storm sewer system is a network of pipes, inlets, outlets, and other conveyance structures, both "gray" and "green," designed to collect stormwater runoff from our streets and homes. The system then conveys that runoff to surface waters like creeks, streams, rivers, lakes and ponds.
Unlike the wastewater systems that carry waste from our homes for treatment, stormwater runoff that is conveyed through storm sewers is not treated. Instead, it ends up in waterways untreated.
As Johnson County continues to grow and develop, it is important to remember that existing storm sewer system still needs to be maintained. It is essential for the Stormwater Management Program to assist cities with funding the inspection and replacement of their older, degraded storm sewer systems.
Strategic Asset Management Plan

The System Management Program within the Stormwater Management Program accounts for approximately 30% of the program budget. The program provides a 50% cost-share with cities for replacement of eligible storm sewer assets.
In 2016, the Strategic Asset Management Plan established the need, funding and procedures for improving the overall condition of stormwater systems in the county. The plan provides guidance for prioritizing storm sewer inspection and replacement through the following processes:
- Creating a countywide asset registry
- Developing criteria for calculating risk for prioritization
- Developing standards and policies
- Establishing funding and maintenance procedures
