Fertilizing your lawn? Don’t guess – Soil Test!
Mow Right and Keep Grass on Site!
If grass clippings enter storm drains, they are carried to creeks and streams causing algae growth and water pollution. Follow these easy steps to protect water while keeping a healthy lawn!
- Follow the 1/3 rule - Never remove more than 1/3 of the leaf blade when mowing
- Raise mowing heights to the highest recommended height during stressful periods
- Sharpen blades after every 10hrs of use
- Avoid mowing within 48hrs of pesticide application
- Leave grass clippings on the lawn to grass cycle nutrients. Grass clippings left on the lawn can contribute up to 30% of a lawn's nitrogen requirements for the year!
- Always sweep or blow grass clippings back into lawn to keep them out of streets and creeks!
If yard waste enters storm drains, it flows untreated to creeks and streams. Too much yard waste creates more food for plants. In water, this plant food increases algae growth. High levels of algae growth decreases oxygen in the water. Without oxygen fish can't survive and recreational activities may decrease.
What is the NWA Urban Stormwater Education Program?
Seventeen Northwest Arkansas cities, Benton and Washington counties, and the University of Arkansas-Fayetteville are partnering with the U of A Division of Agriculture Cooperative Extension Service and the NWA Regional Planning Commission on a regional approach to stormwater management.
Both the EPA and the Arkansas Department of Environmental Quality have recognized the collaborative NWA Urban Stormwater Education Program as an innovative and effective pollution prevention education effort to help protect the region's water resources.
Arkansas Stormwater Education
What is stormwater runoff?
When it rains, snows or sleets in Arkansas, where does that water go? Does it soak into the ground? Does it sit in puddles until it evaporates? The water actually does both of those things, but some of the water will also flow over the land surface, heading downhill to the nearest ditch or stream. This is called stormwater runoff.
Why is stormwater education important?
In Arkansas cities and towns, the water cannot soak in through the pavement, rooftops, and concrete like it can into the soil. This means that there's more stormwater runoff in cities than in forests and fields. The water flows off impervious surfaces such as driveways, rooftops, sidewalks, and parking lots, and usually flows straight into a storm drain. These openings along roads and in parking lots connect to pipes which carry the water directly to your local stream or lake.

Know the Flow
Stormwater flows untreated down our streets and drains directly to local creeks. Thanks for doing your part to keep it free of trash and other pollutants such as pet waste, chemicals, auto fluids, fertilizers and yard waste.
