March 13, 2023 — The Bureau of Reclamation broke ground last week to signal the start of a project to remove the lawn at the Lower Colorado Basin Region administration building at Boulder City, Nevada.  The lawn will be replaced with water-saving xeriscaping.

The project, funded by President Biden’s Bipartisan Infrastructure Law, includes transition from grass to xeriscape at the agency’s training center. It is estimated to save more than two million gallons of Colorado River water annually, according to the Bureau’s press release.  Two million gallons of water is 6.14 acre-feet.

“As Reclamation prepares to offer funding opportunities for similar projects to replace lawns and high-water use landscaping with xeriscape that is native to the Southwest, we are looking internally for changes we can make to reduce water use,” said Deputy Regional Director David Arend. “This project will significantly reduce our water use and transition the landscape to blend in with the surrounding desert.”

The Bureau plans on starting the project this month, with a late-June completion date. The project will replace the lawn and associated turf surrounding the facilities with low water usage vegetation, including drought-tolerant and native trees, shrubs, and plants and ensures accessibility under the Americans with Disability Act. When completed, the regional office grounds will feature a meandering composite path surrounded by small groves of native plants, trees and shrubs. Other improvements to the sites include elevated community gathering spots, drip and low-pressure irrigation systems, and interpretive signs profiling the native vegetation and historic artifacts placed at the site.

Reclamation also plans to upgrade the irrigation systems to improve site maintenance. The new irrigation system at the administration building will not use municipal water; instead, it will use raw water from a pipeline in Park Street. The agency is evaluating the feasibility of using an existing raw water pipeline near the training center xeriscape area.

A Look at Xeriscaping.

Xeriscaping is a landscape design technique that focuses on reducing water consumption while still maintaining an aesthetically pleasing outdoor environment. This technique has become increasingly popular among homeowners, environmental enthusiasts and gardening experts. With climate change affecting weather patterns and causing more frequent droughts, xeriscaping has become vital to sustainability efforts. In this blog, we will explore the key principles of xeriscaping and provide you with practical tips to transform your outdoor space into a water-efficient haven. Whether you live in an arid region or simply want to save money on your water bills, xeriscaping is a great way to create a beautiful and sustainable landscape. Let’s dive in and discover how to xeriscape!

One crucial element of this sustainable landscaping practice is selecting plants that are native to your area. Here are some reasons why:

1. They are adapted to your climate: Native plants have evolved to thrive in your specific climate, meaning they will be better equipped to handle weather patterns and drought conditions in your area.
2. They require less maintenance: Because they are naturally suited to your region, native plants will require less maintenance and water to remain healthy.
3. They support local ecosystems: Choosing native plants helps to support local wildlife habitats, as well as maintain the overall biodiversity of your area.

You can also visit local nurseries to find a selection of native plants that will work well in your xeriscape.

Water-wise hardscaping.

Reduce the amount of hardscaping in your landscaped areas to save on water usage.  By reducing the amount of hardscaping in your landscaped areas, you can save water and create a more sustainable outdoor space. Here are some tips to help you get started:

1. Choose permeable surfaces: When designing a water-wise hardscape, choose materials that allow water to seep through, such as gravel, permeable pavers, or flagstone. This will reduce runoff and help water to penetrate the soil.
2. Opt for natural elements: Incorporating natural elements like boulders, rocks, and logs into your landscape design can help to create a more natural look that requires less water. Plus, these elements can provide habitat for wildlife.
3. Consider alternatives to turf: Instead of having a traditional grass lawn, consider using groundcovers like thyme, chamomile, or creeping Jenny to create a lush green carpet that requires less water. Artificial turf is also an option, but keep in mind that it can become hot and uncomfortable to walk on during the summertime.
4. Use shade wisely: Trees and other large plants can provide shade and help to reduce the amount of water that evaporates from your landscape. Be strategic about where you plant trees, placing them in areas where they can provide the most shade to your home or outdoor living spaces.

By reducing the amount of hardscaping in your landscape design, you can create a more sustainable outdoor space that requires less water. Plus, by using natural elements, shade, and ground covers, you can create a landscape that is beautiful and functional. So, take the time to plan and design a water-wise hardscape that works for your home and property.

Less lawn, more plants.

Minimize the lawn areas in your landscape design to increase the number of drought-tolerant plants. An important aspect of xeriscaping is reducing the amount of lawn areas in your landscape design. Here are some tips to help you minimize your lawn and increase the number of drought-tolerant plants:
