Low Water Landscaping Rebate



Landscape irrigation can be a significant chunk of your water bill during the summer. By switching from a grass lawn to a low water-use landscape design with low-water, drought-tolerant, native plants, you can save both water and money! City of Flagstaff water metered customers can contact the Water Conservation office at (928) 213-2116 to schedule a FREE pre-removal (i.e. when your grass lawn is still intact) inspection of their site to find out if they may qualify for a low water landscape rebate. No rebate will be issued to sites that have already allowed their grass to die or if the grass has already been removed.

Low Water Landscape Rebate Policies:

  • Rebate amount is $0.25/square foot of grass lawn removed
  • The home-owner must replace grass lawn with at least 50% low-water use, native plants. This is because plants and mulch can help decrease the heat island effect, absorb stormwater run-off, and provide beneficial habitat for pollinators and migrating insects. 
  • No spray irrigation is allowed in the eligible area
  • No ponds or fountains may be on site
  • The site must demonstrate water savings to qualify (i.e. you need to calculate the water use of the newly installed plants) * Worksheet in development.
  • Applicant must agree to have a water checkup for indoor water use
