It’s nearly July and the gardens are green and full of early summer blossoms – using just rainwater.
Late last week the City of Scottsbluff finally turned the water on the downtown gardens, about three months after lawn watering began around the city. Native and well adapted plants use much less water than traditional turf once established. They’re also drought hardy, provide needed habitat for pollinators and create a distinct sense of place with a plant palate tailored for the Nebraska Panhandle.
The City of Scottsbluff, working with the Nebraska Forest Service and Nebraska Statewide Arboretum, has recently completed a project that will help reduce stormwater runoff and pollution. We started with a parking lot that had over 16,000 square feet of impervious surface and no landscaping. We broke out over 4,000 square feet of concrete and replaced it will trees, shrubs, grasses, and perennials. Not only did we reduce the impervious surface area of the parking lot by about 1/4, we also designed the project so that runoff from the impervious areas that were left would run into the landscaped areas, where much of it can be filtered into the soil and utilized by the plants. Keep reading for a step by step explanation of what went into this project. Continue reading Sustainable Landscaping Reduces Stormwater Pollution
The planted area you see pictured below is a bioswale. A bioswale is a long, often linear depression in the ground that allows water to move from one location to another. It has gentle side slopes where plants can be grown to slow water enough to filter pollutants and allow more runoff to filter into the ground. This bioswale collects all the water from the roof of the library and directs it to the storm drain at the bottom of the swale. Roof runoff often carries many pollutants, such as leaf litter, bacteria and algae that grow in gutters, and bird droppings. The plants in the bioswale will help remove these pollutants before the runoff enters the storm sewer system, where it travels directly to theNorth Platte River.
This bioswale was the Eagle Scout project for Spencer Lake. Lake worked with the City of Scottsbluff to complete the project with help from members of Boy Scout Troop 13 and the UNL Master Gardeners. The project was designed by Amy Seiler and was funded in part with grant funds from the Greener Nebraska Towns Initiative and in part by the Lied Scottsbluff Public Library Foundation. The day of the installation, we had 29 volunteers work for a combined 100 hours.

The City of Scottsbluff has been selected by the Nebraska Forest Service as a member community in the Greener Nebraska Towns (GNT) Program. This program is designed to improvethe long-term sustainability of member communities. Scottsbluff will be receiving a total of $55,000 in grant funding, $30,000 of which will be allocated to tree planting, and $25,000 of which is to be spent on waterwise landscaping and stormwater management. We will be implementing demonstration projects that incorporate sustainable landscaping, tree planting, and stormwater best management practices, such as rain gardens, bioswales, and porous pavement. We will also be working with residents to plant trees and improve irrigation efficiency. Stay tuned to hear more about everything that we will be undertaking as part of this initiative!
