Bell Road, Suite 3 Nogales, AZ 85621 (520) 761-1814 www.azwater.gov Official Official Regulatory Regulatory List List for for the the Arizona Arizona Department Department of of Water Water Resources, Resources, Santa Santa Cruz Cruz Active Active Management Management Area Area Low Water Use Drought Tolerant Plant List Updated April 2009 An advisory committee of local plant experts reviews all applications for modification and submits recommendations to the AMA Director for final consideration. Applications for additions, deletions or exceptions to this list may be submitted to the Department of Water Resources, Santa Cruz Active Management Area Office for consideration. Phone: (520) 7611814. The list and application forms may be downloaded from the ADWR website at www.azwater.gov. The plants on this list can be grown in the Santa Cruz County area with very low to moderate supplemental irrigation once they are established. Supplemental irrigation should be of sufficient quantity to saturate the plant’s root zone. All plants listed can grow with less water than traditional high water-use landscape plants and do not require more than the ADWR regulations for low wateruse plants in the Santa Cruz AMA, a maximum of 18 inches of supplemental irrigation on an annual basis, not including rainfall. In addition to water requirements, other suitability factors (e.g. highly invasive, cold hardiness, etc.) may be considered to determine acceptability of individual plants for addition to the list. This list can also be used as a resource for residents and businesses that are interested in conserving water. The list provides a wide array of plants to accomplish a variety of low water-use landscape designs. This official regulatory list was developed to guide the regulated community in choosing low water-use and drought tolerant plants for landscaping. Landscaping planted after January 1, 1987 within publicly owned rights-of-way and irrigated with groundwater may be planted only with plants listed on the ADWR Low Water Use/ Drought Tolerant Plant List for the Santa Cruz AMA. The director may waive this requirement under special circumstances. This requirement does not apply to any portion of a residential lot that extends into a publicly owned right-of-way. Many local jurisdictions have adopted this list for regulatory purposes; contact your local jurisdiction for their landscape requirements.
