2016 Strategic Plan

Johnson County’s Urban Services Division engaged Black & Veatch Corporation (Black & Veatch) to lead the development of a comprehensive update of the SMP Strategic Business Plan. A Steering Committee was established and provided the Black & Veatch team with essential information, input and guidance throughout the updating process. A cross section of stakeholders comprised the Steering Committee, including staff and elected officials from smaller and larger cities as well as officials from the County Commissioner, County Manager’s office and Johnson County Public Works & Infrastructure department. The DRAFT report is available at the links below. 

Implementation Sub-Committees

The following sub-committees have been formed to assist with developing the necessary policies and procedures to implement the strategies set forth in the 2016 Strategic Plan.  The sub-committees began meeting in February 2017 and will continue to meet for 18 months. 

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 rain or snow that "runs off" across the land instead of seeping into the ground. Runoff is increased from survaces which do not absorb water such as roads, parking lots, and roofs. The storm drains along streets and curbs allow rain and melting snow to move from the streets into a network of manmade pipes and natural channels ending up in our streams and lakes. Stormwater is not treated before it ends up in a stream, lake, or river. Stormwater replenishes our sources of drinking water – lakes, streams and groundwater. Clean 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 Stormwater Pollutants

  • Automotive fluids
  • Litter, including cigarette butts
  • Fertilizer and weed killer from yards
  • Grass clippings, leaves and other yard waste
  • Pet waste
  • Soap, paint, cleaning supplies and other household chemicals
  • Sediment from exposed ground

Stormwater pollution can:

  • Increase the risk of illness and harm to individuals, particularly children, and pets who come into contact with the water
  • Degrade the quality of water we use for drinking, irrigation, recreation and industry; which could cause increased treatment costs
  • Damage the natural ecosystems of our waterways and damage the plant and animal habitat
  • Clog storm drains with sediment and trash and require more maintenance and cause street flooding


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:;00 

  • 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.

Flood 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 non-perishable food, drinking water, a flashlight, and basic medical supplies. Find a complete list of a basic disaster supplies kit at www.ready.gov/kit.
  • If your basement has the potential for flooding, store your kit on a shelf and 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.
  • Never drive through a flooded road, always "Turn around, Don't Drown". 
  • 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.

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 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 update 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 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 of one percent 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 $200 million of stormwater study, design and construction projects have been, or are currently being completed through the SMP and the cities.
  • For the 200-plus projects, approximately $150 million has been paid for by the 1/10th of one percent 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.

Annual Budget

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


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.


Policies and Procedures

The Stormwater Management Program operates and functions as defined in the Board of County Commissioner approved Program Policies and Administrative Procedures. These policies and procedures are reviewed on a regular basis and revised as necessary to meet the changing needs of the cities and the changing requirements for stormwater management.


Pool Water Disposal

Residential Pool Water Disposal Guidelines

Swimming pool and hot tub water contains many chemcials, including large amounts of chlorine, that are harmful to streams and lakes. Treated pool water is especially harmful to the aquatic life in these waterbodys. If water drained from pools is allowed to enter the storm drain system directly, it can harm fish and other aquatic life. Any water drained to the street or a storm drain flows directly to streams and lakes without treatment, therefore, the guidelines for properly disposing pool water must be followed. 

Releasing chlorinated pool water or backwash filter waste into a stream or storm drainage system is prohibited by City, County, and State regulations. Follow the steps below to safely and legally discharge pool water.

Traditional chlorine pools

Step 1: Discontinue the addition of chlorine 5 to 7 days before you plan to drain the water. This will allow the chlorine to dissipate naturally.

Step 2: Test the chlorine level and the pH of the water. If the residual chlorine level is less than 0.1 ppm (mg/L) and the pH is between 7 and 8, the water is safe to drain. 

Step 3. Drain the water. Direct the water in a way that does not cause it to flow onto a neighbor's property, cause nuisance conditions, or erosion problems. It is preferred that you discharge the water to a grassy area on your property and not allow the water to leave the property. 

Salt water pools

Sanitizing pool water using a chlorine generator is becoming increasingly popular in Johnson County. These systems use dissolved salt (NaCl) in the water and the use of electrolysis to create the chlorine needed to sanitize the water. Pool water treated this way requires slightly different for guidelines for disposal because the residual salt concentrations are too large (usually 3,000 ppm (mg/L)) to discharge to the storm drain system or streams. The State of Kansas acute aquatic life water quality standard for chloride is 860 ppm.  

Step 1: Discontinue the addition of salt. This will stop the generation of chlorine and allow the chlorine in the pool water to dissipate. 

Step 2: Test the chlorine level and the pH of the water. If the residual chlorine level is less than 0.1 ppm (mg/L) and the pH is between 7 and 8, the water is safe to drain. 

Step 3: Drain the water to a grassy area, it cannot be drained to the street or storm drain. When draining to a grassy area on your property take care to not allow the water to flow to trees or landscape beds. Do not allow the water to leave the property from which it originated. All pool water discharge and rinse water must soak into the ground. Typical lawns in Johnson County can tolerate the residual salt contect in the water if you spread the flow out to different areas and water (with tap water) the affected area throughly (1-2 inches) to flush the residual salt through the soil. 

Additional information

Water from backwash filter systems are not allowed in the storm sewer system. It is preferred that this water is directed to the sanitary system through a drain in your home, however, you may discharge the water on your lawn only if all of the water soaks into the ground and no water is allowed to leave your property. Used pool filters should be placed in your trash. 

Contact your city for additional information or questions.

Stormwater Management

Flood Mitigation to Achieving Multiple Stormwater Management Goals

Get the water off the streets! That was the rallying cry for stormwater management for most of the 20th Century. Stormwater control was relegated to a supporting role in county and municipal street departments. While drinking water and sewer systems were operated as revenue generating enterprise funds, funding for stormwater generally remained as part of the overall street maintenance budget. Consequently, comprehensive planning for storm sewers was given a low priority and new construction in one area often lead to increased flooding downstream.

The significance of the problem made major news in the Kansas City Metro area on September 12, 1977 when 16 inches of rain drove Brush Creek, which flows through Praire Village and Mission Hills and into Kansas City, Missouri, over its banks. Northeast Johnson County communities experienced major flooding and one person lost their life on the Kansas side of the state line. Even more extensive damage occured on the Missouri side where 25 people died and nearly $100 million worth of property damage was sustained. For the next 13 years, Johnson County and its 20 incorporated cities continued to try and address their flooding problems independently of one another, but with no dedicated funding source, little progress was made.

Recognizing the problems inherent with limited funding and the need for a more regional approach to effectively managing stormwater, the Kansas State Legislature passed legislation in 1988 that granted Counties the power to levy a retail sales tax up to 1/10th of one percent for the purposes of paying for the cost of stormwater management and flood control improvements. In 1990, the Johnson County Board of County Commissioners adopted Resolution No. 38-90 which implemented the tax and created the Stormwater Management Program (SMP). The Stormwater Management Program administers the funds collected through this tax on behalf of the cities and provides other types of stormwater planning assistance within Johnson County. To-date the SMP has helped cities fund over $200 million of stormwater improvement projects with Johnson County cities.
