Plant factors cited in this chapter are derived from the publication "Water Use Classification of Landscape Species". Plant factors may also be obtained from horticultural researchers from academic institutions or professional associations as approved by the California Department of Water Resources (DWR).

"Project applicant" means the individual or entity submitting a landscape documentation package required under California Code of Regulations] Section 492.3, to request a permit, plan check, or design review from the local agency. A project applicant may be the property owner or his/her designee.

ETo is expressed in inches per day, month, or year as represented in Appendix (Chapter 2.7, Division 2, Title 23 of the California Code of Regulations), and is an estimate of the evapotranspiration of a large field of four- to seven-inch tall, cool-season grass that is well watered. Reference evapotranspiration is used as the basis of determining the maximum applied water allowances so that regional differences in climate can be accommodated.
