Green Roofs

Green roofs help manage stormwater by capturing rainfall.

The Low Impact Development (LID) Atlas was created for the National Nonpoint Education for Municipal Officials (NEMO) Network by the Connecticut NEMO Program and the California Center for Water and Land Use (http://lidmap.uconn.edu/). The LID Atlas is an interactive tool that provides examples of LID implementation throughout the country.

Low Impact Development

The key premise of low impact development (LID) is to allow natural systems to manage stormwater when and wherever possible. LID takes advantage of existing natural features and also designs and constructs systems to imitate natural processes, for example, green roofs, bioretention gardens, and permeable pavement.

Permeable Pavers

Permeable pavers let water pass through the spaces between them which are often filled with small gravel or sand.

Rain Gardens

You can reduce water runoff from your yard by planting a rain garden. A rain garden is a small depression planted to flowers and ornamental grasses. It is designed to temporarily hold and soak in rain water from a roof, driveway or open area. A rain garden is not a pond or wetland. It is dry most of the time and holds water after a rain. Water collected in the rain garden slowly soaks into the soil and disappears in less than 48 hours.

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.

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.

Landscape Management Practices

Aim downspouts towards planted areas or pervious hardscape and away from impervious paved areas. Collect rainwater from rooftops in rain barrels or cisterns for reuse in landscape irrigation. Amend soil with organic matter. Core aerate lawns to help avoid or reduce soil compaction, increase water infiltration, and promote healthy root systems. Follow University and label recommendations and calibrate spreaders when using fertilizers and pesticides. Only use these products when needed. Read and follow label directions for all lawn chemicals.

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.

Sustainable Landscapes

Landscapes which are sustainably designed, installed and managed conserve water, lower the rate and volume of runoff water from rain, snowmelt and irrigation, and help reduce the amount of pollutants reaching surface water. Water related benefits achieved with sustainable residential, business, and community landscapes include:

Stormwater

What is stormwater? It's water from rain or melting snow. Watch the video and learn about rain water runoff and why it can be a problem.

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

How and Why to Separate Turf from Ornamentals

Regardless of the mix, the goal for green minded gardeners is to grow, plant and care for healthy landscape plants and turf. One of the most important factors in the success of these endeavors is getting to know specific needs of the plant material and how they can be combined effectively in a landscape without compromising the needs of each component.

Separate Turf and Ornamentals

Do you have trees growing right in the middle of your lawn? Do you swear under your breath every time you mow, having to trim around them and practice some fancy footwork trying to maneuver the mower around the trunk? If so, perhaps it's time to redesign your landscape, separating the grass and all of the other plants. If you are building a new home, or moving to one with little or no landscaping, you can avoid this maintenance nightmare by simply thinking of turf as a part of the landscape unto itself.

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.

Nutritional Value for the Landscape

Processing lawn clippings and tree leaves into the lawn provides nutritional value as well as reduces waste. Generally, turf clippings contain 6-7% nitrogen, 0.5 to 1.0% phosphorous and 2-4% potassium; when returned to the lawn, they can account for a fourth of the lawn's fertilizer applications each year.

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.

Odor Management

Odor emission is of great concern to the general public. An odor management plan is required in the permit application for livestock operations with more than 1,000 animal units. Producers need to understand odor emission from animal housing, manure storage and handling, and land application and available management options.

Manure Value

Manure is often an under-valued resource. When well-managed and properly applied, it reaps many benefits. The benefits can be seen in the photo to the left, but are not captured in much of the field because of errors in application.
