Lawns, Gardens & Landscapes

Your landscape includes your lawn, trees, shrubs, flowers, vegetable garden, and groundcovers. The lawn is likely a prominent part of your landscape. While the lawn may need watering and frequent care, it adds beauty to the community and a well-maintained lawn offers many benefits:

  • absorbs rain water runoff
  • decreases soil erosion
  • promotes neighborhood pride
  • reduces the urban heat island effect
  • increases property values
  • provides space for recreation and relaxation

Building Soils

Water should never be applied at a rate faster than it can be absorbed by the soil. Soil properties that govern water infiltration (movement of water into the soil) are texture and structure.

Common Pollutant Types

Sediment (sand, silt, and clay particles): Bare spots in lawns and gardens, lawn and landscape renovation projects, sloping areas, soil washed from vehicles, roof tops and other hard surfaces like driveways, pond or stream bank erosion, home construction.

Landscape Design Practices

Install rain gardens in locations where they catch and temporarily hold rainwater. Use natural drainage patterns, site grading, berms (planted earth mounds) or other methods to channel rainwater away from impervious surfaces (i.e. pavement) onto planted areas such as grass swales, filter strips, or rain gardens. Plant and maintain healthy plant cover, especially on slopes to stabilize the soil and prevent erosion. Select plants adapted to the site and maintenance level.

Publications and Resources

Nebraska Extension Educators and Specialists have developed many resources to help you use water more efficiently and help keep it clean. Nebraska Extension has also developed materials to help youth learn about water and how to save it and keep it clean. Read on for a listing of all of these great resources for your landscape

Water Zones

Once good soils are in place, create water zones. Water zones are distinct sections of your property which contain plants with similar water needs. Group ornamentals into H-M-L zones in the landscape. Keep each distinct plant group by themselves – set watering minutes per zone accordingly.

Green Roofs

Green roofs help manage stormwater by capturing rainfall.

Key Tips for Reducing Pollutants

Water pollution can come from a variety of sources. Soil, grass clippings, fertilizer, pesticides, paint thinners, and motor oil can pollute water if picked up by stormwater runoff.
