3.4.5 Xeriscape Planting Design Principles

Xeric planting refers to those materials that will thrive under low-water or no-water conditions. For aesthetic design within the roadway, multiple factors must be considered for vegetation to thrive:
  • Plan and design:
     Base the design on zones with different water requirements.
  • Soil improvement:
     Increase the amount of organic material within the soil profile.
  • Select appropriate plant material:
     Use plant material native or naturalized to the region.
  • Reduce grass/lawn areas.
  • Water conservation:
     Avoid overwatering by utilizing drip irrigation.
  • Use mulch:
     Cover the exposed soil to retain moisture.
  • Perform appropriate maintenance:
     Maintain mulch layers, avoid over-mowing and over-fertilizing.
