About SMP

Johnson County Stormwater Management Program

The Johnson County Stormwater Management Program (SMP) is a department of the County government that partners with the 20 cities in Johnson County as well as other cities, counties and agencies in the Kansas City metropolitan region on stormwater management related issues.

Stormwater management issues addressed by the SMP include:

  • Provide 75 percent of funding for study, design and construction of stormwater improvements in Johnson County communities.
  • Update and maintain Countywide floodplain mapping
  • Manage grant funded projects intended to mitigate flooding conditions and improve the water quality of stormwater runoff.
  • Provide technical support to the cities on stormwater management related issues.
  • Provide public education and outreach associated with stormwater management.
  • Coordinate and collaborate with communities, counties and local, regional, state and federal agencies in the Kansas City Metropolitan region on stormwater management related issues.

SMP aims to provide the level of service and standard of care Johnson County property and business owners expect and deserve.

The SMP works directly with cities to fund design and construction projects. If you believe you have a flooding problem in your neighborhood, contact your city.


Who Does What In Stormwater Management?

The Johnson County Stormwater Management Program partners with Johnson County cities to fund the planning, design and construction of projects to alleviate flooding and improve water quality issues from the broad countywide level of the watershed. If you feel you have a flooding condition or a water quality issue in your neighborhood or know of one in your community, please contact your city.

The real “front line” of stormwater management occurs at the city level, where staff and the public interact to make the choices that best serve their community.

Cities manage localized flooding, erosion and water quality issues. City staff and elected officials determine projects needed in their communities.

The SMP provides cities with 75 percent of finding for eligible projects, using a countywide sales tax.


About Water Quality

What is stormwater and why is it important?

Stormwater is water that accumulates on land as a result of storms, and can include runoff from urban areas such as roads and roofs. Stormwater from rain or melting snow replenishes our sources of drinking water – lakes, streams and groundwater. The cleanliness of our stormwater is vital to our quality of life and to the quality of our drinking and recreational waters.

Everyone in Johnson County -- including you -- has an important role to play in keeping our stormwater – and ultimately all our local water resources -- free of harmful pollutants and help Johnson County remain a sustainable community with a plentiful and safe water supply.

The Storm Drainage System and How It Works

The storm drainage system comprises many storm drains, pipes and channels. Storm drains are openings in streets or curbs that are sometimes covered with metal grates. The storm drains allow rain and melting snow to move from the streets into a network of manmade pipes and natural channels. When water flows across yards, streets and other surfaces, it picks up contaminants and carries the runoff untreated to a natural body of water. Dumping wastes into a storm drain or on the ground directly affects the environment, damaging potential sources of drinking water and recreational waters and endangering wildlife and habitat.

Potential Hazards

Stormwater washes natural and man-made materials into the storm drains where it flows untreated into our streams, rivers, lakes and groundwater. These materials are nothing you would want to drink or splash in:

  • Oil
  • Grease
  • Tire residue
  • Anti-freeze
  • Petroleum products
  • Litter
  • Fertilizer
  • Weed killer from yards
  • Grass clippings
  • Leaves and other yard waste
  • Animal wastes
  • Cigarette butts
  • Cleaning supplies
  • Paint
  • Solvents
  • Sediment (from construction sites)
  • Other microorganisms

Effects of Stormwater Pollution

Even a simple spring shower can compromise the quality of our waters. Something as common as pet waste, or every day activities, such as washing your car or fertilizing your lawn, can pollute waterways.

Stormwater pollution may:

  • Lead to increased risk of disease and harm to individuals, particularly children, who come into contact with the water
  • Degrade the quality of water we use for drinking, irrigation, recreation and industry
  • Damage the natural ecosystems of rivers, streams, lakes and wetlands
  • Clog storm drains with sediment and trash and require more maintenance
  • Threaten the survival of plants and animals


Advisory Council

Stormwater Management Advisory Council

The Board of County Commissioners adopted Board Resolution No. 76-90—creating the Johnson County Stormwater Management Advisory Council (SMAC). SMAC is an advisory group composed of one appointed representative for each of Johnson County 's 20 cities as well as non-voting members from the four surrounding counties, Kansas City , MO , and the Mid-America Regional Council. SMAC primarily operates as an advisory body to the Board of County Commissioners and performs the following functions:

  • Review recommendations of the Stormwater Management Program
  • Make recommendations to the Board of County Commissioners

In addition, SMAC provides the mechanism to complete the following efforts:

  • Ensure the stormwater funds collected through the 0.1 percent sales tax levy are consistently applied using the same rational basis without concern for jurisdictional and political boundaries.
  • Use the stormwater funds collected through the 0.1 percent sales tax levy to correct the more severe flooding problems throughout the County with cost-effective solutions.
  • Provide a think-tank to consider new and innovative ways to properly manage stormwater

SMAC operates under and is governed by Board of County Commissioner approved By-laws.

Floodplain Management


The Stormwater Management Program (SMP) contracted for seven watershed studies between 1998 and 2002. These studies were part of a county-wide effort to provide the following information:

  1. identify existing and potential future flooding problems;
  2. develop planning level solutions to mitigate flooding problems;
  3. generate new 1% chance (100 year) floodplain maps based on current conditions and fully urbanized conditions; and
  4. develop the data required by the Federal Emergency Management Agency (FEMA) to create updated FEMA regulatory 1% chance floodplain maps.

Through this effort, the SMP and the cities have created a tool that will assist in providing a public service to help protect the health, welfare and safety of Johnson County residents and visitors.

Additional Information

The floodplain mapping is complete and was adopted by FEMA on August 3, 2009. Johnson County floodplain mapping information can be found at the following locations:

If you have questions about the floodplain information or want additional information, contact the floodplain administrator for your community.


Funding and Budget


Dedicated sales tax

Since the Kansas Legislature approved a 1/10th-cent sales tax for the purpose of funding stormwater management efforts, Johnson County 's Stormwater Management Program (SMP) has provided 75 percent of funding for eligible projects in cities.

  • To date, nearly $100 million of stormwater study, design and construction projects have been, or are currently being completed through the SMP and the cities.
  • For the 150-plus projects, approximately $75 million has been paid for by the 1/10th-cent sales tax.
  • On average, SMP spends more than 90 percent of the total budget annually to study, design and construct stormwater projects and to fund county and regional stormwater quantity and quality related projects. Improvements include widening open channels and replacing culverts and bridges, protecting the natural stream corridor and enhancing water quality.
  • The SMP and the cities have spent more than $9 million with an additional $3 million of state and federal assistance to buy out and remove flood-prone homes in the last 10 years.

Annual Budget

Program expenditures as approved by the Johnson County Board of County Commissioners


History and Goals

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.

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 and runoff issues throughout the region.


Business Plan

In 2002, the SMP completed a comprehensive review of it's existing polices, project management, and program direction to ensure continued success in the future.  The results and recommendations of this process can be found in the Business Plan documents below.

Summary Report

Full Assessment Report


Localized Flooding

Water in basement, home, business

For help with flooding issues in buildings and structures, please contact your city.

If you cannot determine the source of the water entering your home, contact your city hall or a plumber.

Water in yard, drives, drainage areas

If you have water pooling in your yard for long periods of time, contact your city to determine if this is a city responsibility issue or a homeowner issue.

Water standing in the streets for long periods of time, clogged/blocked inlets, culverts and bridges?

Contact your city and inform them of the situation.

Water in car, truck, vehicles

Restoring cars and vehicles that have been partially or completely submerged under water requires professional attention. Check with your dealer or look in the telephone directory for automobile service and repair firms.

Please visit our page on flood safety.


Localized Flooding Emergencies and Safety


If you are experiencing a life threatening situation, call 911. Otherwise contact your city to request help.

Flood Safety

Before a flood:

  • Prepare an emergency kit that includes a flashlight, basic medical supplies, drinking water, etc….
  • If your basement has the potential for flooding, elevate boxes and other items off the floor.

During a flood:

  • Do not walk or drive through moving water. Although appearing harmless, water only 7 inches deep can move rapidly and with great force, posing a significant threat.
  • Stay away from downed power and electrical lines.
  • Stay away from streams during storms as water can rise rapidly and without warning.
  • Keep children away from creeks or storm drains during and after a storm.

After a flood:

  • If the path is dry, turn off the electricity at the main breaker box or fuse box – if you have to step in water to do so, call an electrician.
  • Don't use wet appliances or motors until they have been taken apart, cleaned and dried.
  • Watch your step inside and outside: surfaces may be slippery and covered with debris.
  • Use a flashlight to inspect for damage.
  • Because it is difficult to identify if water in a basement is stormwater or from the sanitary sewer, treat all surfaces and furnishings as if they are unhealthy.
  • Protect yourself with good personal hygiene: wear rubber boots and gloves; wash hands with soap and water; protect open sores or wounds from contact with the water.
  • Disinfect and clean everything that got wet. If in doubt, throw it out.
  • Visit Johnson County Wastewater for specific guidelines for cleaning up after a sewer backup.
  • Find out if a "Boil Water" order is in effect for drinking water.

NPDES Information


Below is information collected or produced by the Stormwater Management Program to assist NPDES communities with meeting NPDES regulations.

Stormwater Management Plan

The stormwater management plan outlines activities that the Stormwater Management Program will perform on behalf of Johnson County NPDES Phase 2 Stormwater permit holders. Each permitted city has been provided this plan.

Johnson County Stormwater Public Awareness Survey

In 2006 the Stormwater Management Program conducted a countywide survey in an effort to measure the impact that stormwater and water quality education efforts in the region are having on the public's overall awareness and behavior. Results from the 2006 stormwater public awareness survey provides a benchmark for objectively evaluating education initiatives over time. A follow up survey was conducted in July 2009. Results from the 2009 survey will help the Stormwater Management Program and municipalities in the County assess the effectiveness of education initiatives undertaken in the last three years.

2009 Survey Instrument and Results:

Year 4 Annual Report – Covers activities from October 1, 2007 to September 30, 2008:

Year 5 Annual Report – Covers activities from October 1, 2008 to September 30, 2009:


NPDES Procedures


The U.S. Clean Water Act (CWA) requires water quality standards to be established and enforced by federal and state law. The CWA prohibits the discharge of pollutants from identifiable sources – such as a storm drain – into surface waters without a special permit.

The permit is called National Pollutant Discharge Elimination system (NPDES) and was issued by the Kansas Department of Health and Environment (KDHE) to multiple cities and Johnson County in 2004. All permit holders are required to prepare a Stormwater Management Plan describing how they will address required program elements for the Years 2005-2009, including best management practices, a schedule of activities and the entity responsible for implementation.

Model Stormwater Management Program Plan

To assist cities and the county with complying with NPDES regulations, Johnson County Stormwater Management Program has developed a model stormwater management plan. The public can obtain a copy of the model plan by visiting Johnson County Infrastructure and Transportation Offices at 1800 West 56 Highway, Olathe, Kansas, during regular business hours or can request a copy by calling 913-715-8333.

The plan outlines activities that the Stormwater Management Program will perform on behalf of Johnson County NPDES Stormwater permit holders. Each permitted city has been provided this model plan.

The purpose of the plan is to reduce water quality impacts from stormwater runoff to the maximum extent practicable by addressing six minimum control measures.

Minimum Control Measures:

  1. Public Education and Outreach
    Public education and outreach ensures greater support and compliance for the program. This measure relies on forming partnerships, using educational materials and strategies and reaching diverse audiences.
  2. Illicit Discharge Detection and Elimination
    This measure focuses on decreasing pollutant levels from illicit discharges – illegal pollution – that can significantly degrade water quality and threaten aquatic, wildlife and human health. The measure includes locating problem areas, finding the sources, removing/correcting illegal connections to the storm drainage system and documenting actions taken.
  3. Post-Construction Runoff Control
    Runoff from areas undergoing development/redevelopment has been shown to significantly affect bodies of water. This measure will help prevent damage to aquatic life and property while using the most cost-effective approach to stormwater quality management.
  4. Public Participation/Involvement
    An active and involved community is vital to the success of a stormwater management program. Public input is needed in the development and implementation of the program.
  5. Construction Site Runoff Control
    Polluted stormwater runoff from construction sites often flows to the storm sewer system and ultimately is discharged into local rivers and streams. The introduction of silt and pollutants from construction sites can harm the physical, chemical and biological components of a community's water ways.
  6. Pollution Prevention/Good Housekeeping
    Municipalities conduct many activities that can pose a threat to water quality if practices and procedures are not in place to prevent pollutants from entering the stormwater system.

For fact sheets about each of the six minimum control measures, visit the EPA Web site at http://cfpub.epa.gov/npdes/stormwater/.
