History of SMP

In 1988, the Kansas Legislature authorized counties to adopt a 1/10th-cent sales tax for the purpose of funding stormwater projects. Johnson County was the only county to implement the tax. These funds, dedicated to stormwater management, allow Johnson County 's Stormwater Management Program (SMP) to create a yearly stormwater management plan and provide 75 percent of funding for eligible projects in Johnson County and the cities.

The Board of County Commissioners created the SMP and the Stormwater Management Advisory Council (SMAC) in the early 1990s. SMAC helps coordinate stormwater efforts and advises the County Commissioners on stormwater management related issues.

SMAC is comprised of voting and non-voting members. Voting members are comprised of a representative from each of the cities in Johnson County and Johnson County . Non-voting members are representatives from other communities in the Kansas City metropolitan area, local, regional, state and federal agencies, and interested people.

Current Goals Of The Program

The Johnson County Stormwater Management Program (SMP) is focused on:

  • Keeping the public informed and educated about stormwater and flooding
  • Studying and mapping floodplains
  • Encouraging emergency preparedness for flood events
  • Securing funding for stormwater projects
  • Helping city and county officials coordinate efforts to address stormwater quality and runoff issues throughout the region.
