Yard Waste Management

Yard Waste Management Frequently Asked Questions

Is it OK to dispose of leaves on stream banks? There are leaves there already and I've heard it helps to stabilize the stream bank. No-- It is true that there are trees and other vegetation next to streams and leaves from those trees fall into and around the stream, but as with many things in life, too much can be a bad thing. The natural system is equipped to break down and process the leaf litter that is there naturally, but dumping leaves in or near a stream overwhelms the system. Too much decomposing organic waste adds excess nutrients into our streams and lakes that can lead to unsightly algae blooms which also can be harmful to pets and humans. As algae dies, it uses oxygen in the water, which causes depletion in oxygen in the water for aquatic life and can cause fish kills. 

Is it OK to put leaves in the storm drain? No-- it is illegal to dump anything, other than clean water, into the storm drain. Not only is it bad for water quality because stormwater is not treated, it can cause clogs in storm water catch basins which could result in localized street flooding. And this causes increased maintenance costs for your city, which could result in higher taxes for you. 

Will mulch mowing leaves cause thatch in my lawn? I'm worried because have several mature trees in my yard. No-- research from Michigan State University Hancock Turfgrass Research Center has shown that you can mulch up to 6 inches of leaves into your lawn. To do this effectively, it is best to stay ahead of the leaves and not try to mulch 6 inches at once, but mulch frequently throughout the fall season. Also, make sure and have your mower blade sharpened before the fall season to ensure effective mulching. Research has shown that core aeration and fertilizing your lawn with a fertilizer that has a high nitrogen (N) and low phosphorus (P) content will help break down the leaves into a useable resource for your healthy lawn. (When purchasing fertilizer, check the Nitrogen (N), Phosphorus (P), and Potassium (K) contents. Lawns in Johnson County generally do not need additional phosphorus.) 

Additionally, thatch is not caused by mulching leaves or grass clippings into your lawn. Thatch is caused by many factors which include, frequent and shallow watering, excessive use of nitrogen fertilizer and pesticides, compacted and poorly aerated soils, and infrequent, high mowing. 

Is it OK to blow or rake my leaves into the street-- doesn't the city pick them up? Most cities in Johnson County do not offer a leaf removal service. The street sweepers you may see on your street are there to pick up the leaves that fall on the street and ONLY those leaves that fall on the street. They are not equipped to remove a large amount of leaves, such as those raked intentionally from a yard, The cities of Westwood, Westwood Hills, and Roeland Park do offer a city-wide leaf pick up service, but only on specific days. Contact your city for details. The cities of Fairway and Mission Hills have negotiated on behalf of their residents with a third-party contractor to provide a fee-based leaf-collection service. Most other cities in Johnson County have weekly curbside yard waste collection, but require leaves to be in paper bags or in a container clearly marked as yard waste. 


Water Quality

Regulations for preventing stormwater pollution

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 the National Pollutant Discharge Elimination (NPDES) permit for the Multiple Separate Storm Sewer System (MS4) and are issued by the Kansas Department of Health and Environment (KDHE) to multiple cities and Johnson County. All permit holders are required to prepare a Stormwater Management Plan describing how they will address required program elements, including best management practices, a schedule of activities and the entity responsible for implementation. The six program elements included in the NPDES MS4 permits are listed below:

  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. 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.

  3. 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.

  4. 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.

  5. 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.

  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.


Johnson County, Kansas Permit and Stormwater Management Plan

The Kansas Department of Health and Environment issued a NPDES permit to Johnson County, Kansas in 2014 to regulate discharges into the multiple storm sewer system owned by the County. This permit only covers stormwater discharges into the storm sewer system in the unincorporated area of the County. Most cities in Johnson County also hold NPDES permits with KDHE and are responsible for regulating stormwater discharges within city limits. The permit requires that Johnson County develop a Stormwater Management Plan that outlines how the minimum control measures listed above will be addressed. The permit and stormwater management plan for Johnson County are available at the links below. Comments regarding the County's MS4 program and plan can be submitted, in writing, to the Johnson County Public Works Department, 1800 West Old Highway 56, Olathe, KS 66061.

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 occurred 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.

Pool Water Disposal

Residential Pool Water Disposal Guidelines

Swimming pool and hot tub water contains many chemicals, including large amounts of chlorine, that are harmful to streams and lakes. Treated pool water is especially harmful to the aquatic life in these waterbodies. 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 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 content in the water if you spread the flow out to different areas and water (with tap water) the affected area thoroughly (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.



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.


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.


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.





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:

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.


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.



All meetings are held at Johnson County Public Works, 1800 W. Old Highway 56, Olathe, KS 66061.



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 surfaces 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 local water resources free of harmful pollutants.  By playing your part you are helping 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 of 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 untreated runoff 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 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, requiring more maintenance and potentially cause streets to flood

​How Can I Help?

We're so glad you asked! You can be a stormwater steward. That means in simple, every day activities, like bagging your pet’s waste or taking your car to a commercial wash, can help keep harmful pollutants out of our waterways. Here is a list of every day activities you can do to help prevent stormwater pollution in our communities.

  • Use fewer lawn chemicals and don't water right away. Try using compost instead of chemical fertilizer. Don't water after applying lawn chemicals and don't apply them before a heavy rainfall is predicted.
  • Clean up after your pets. Carry disposable bags while walking your dog so you can pick up and dispose of pet waste in the trash. In your own yard, pick up pet waste, bag it and put it in the trash. Leaving it in the grass sends unsafe bacteria into the storm drains when it rains.
  • Recycle used oil. Find an oil recycling center near your home or work to properly dispose of used oil. Johnson County has more than 30 used-oil recycling sites, such as gas stations, automotive supply stores and lubrication service centers. For a list of sites, go to www.recyclespot.org
  • Sweep driveways and sidewalks rather than washing them off with the hose. Remove grass clippings, dirt and other debris and dispose of it properly.
  • Use a commercial car wash to minimize the effects on the environment. If you wash your car at home, do it on the grass. Use biodegradable, phosphate-free, water-based cleaners only. Use a spray nozzle to save water.
  • Properly dispose of trash and yard waste. Contact your city hall for your community's instructions for proper trash and yard waste disposal.
  • Use household products as directed. Properly store and dispose of all hazardous household products at a hazardous waste permitted facility.
  • Shop smart. Purchase and use nontoxic, biodegradable, recycled and recyclable products whenever possible.
  • Reduce Stormwater Runoff from Your Home. Consider installing a Rain Garden -- learn more about it here.


About SMP

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 funding for eligible projects, using a countywide sales tax.


You can help your city by identifying and reporting potential sources of stormwater pollution. To report stormwater pollution in your area, call the Stormwater Hotline at 913-715-6900 or fill out this online form.

If reporting pollution after business hours, please call the Johnson County Environmental Department 24-Hour Response Service at 913-715-6900. If you witness discharges of hazardous materials-- dial 911 to contact the fire department.
