Prescott Valley, AZ Landscaping Rules: Native Plants (2026)

Section 13-11-040 is the required landscaping section of Article 13-11 in the Prescott Valley Town Code. Its basic requirements call for automatic irrigation sized to support all living landscaping, with one carve-out: irrigation is not required for undisturbed areas of native grasses and vegetation. Subsection E.6 then provides that, in all cases, undisturbed or re-seeded native grasses qualify as ground cover material toward the erosion and dust control standard, which asks for cover that completely controls erosion and dust.

The off-site strip works the same way. Subsection H.1 requires the area between the property line and the shoulder of the roadway to be landscaped continuously, except where interrupted by paved driveways and drainage ditches, and subsection H.2.a lets undisturbed native grass areas fulfill that requirement. Trees, large shrubs, and hedges are not permitted in that strip except in areas where the Town Engineer has established maximum street construction widths.

Living plants come from the approved plant list in section 13-11-060: the Prescott AMA plant list plus the Prescott Valley supplemental plant list, which the Development Services Department maintains and updates periodically. Trees within the first ten feet of on-site street frontage along pedestrian ways must be Thornless Honey Locust, Chinese Elm, Locust, or Arizona Ash, and parking lot buffer shrubs come from Juniper, Spanish Broom, Mountain Mahogany, Gray Rabbit Brush, or Parney Cotoneaster. Street frontage borders are seven feet wide for multi-family uses and ten feet for other non-exempt uses. Section 13-11-020(B) limits a single-family residence on its own lot, outside a PD zone, to subparagraph H.2 plus screening and lighting provisions, and the AG zone is subject only to Article 13-12 and section 13-11-070. Section 13-11-080(E) requires other grade changes to carry groundcover in a minimum ratio of 50% living vegetation to 50% inorganic groundcover.
