The following definitions are applicable to this article:

"Aggregate Landscape Areas" pertains to production home neighborhoods, common interest developments, or other situations where multiple parcels are undergoing development as one project, but will eventually be individually owned or maintained.

"City" means the City of Santa Ana, a charter city and municipal corporation, or its authorized designee.

"Ecological restoration project" means a project where the site is intentionally altered to establish a defined, indigenous, historic ecosystem.

"Estimated Applied Water Use" or "EAWU" means the annual total amount of water estimated to keep plants in a healthy state. It is based on the reference evapotranspiration rate, the size of the landscape area, plant water use factors, and the irrigation efficiency within each hydrozone.

"Evapotranspiration adjustment factor" or "ETAF" means a factor of 0.7, that when applied to reference evapotranspiration, adjusts for plant factors and irrigation efficiency, two major influences upon the amount of water that needs to be applied to the landscape. A combined plant mix with a site-wide average of 0.5 is the basis of the plant factor portion of this calculation. For purposes of the ETAF, the average irrigation efficiency is 0.71, therefore, the ET adjustment factor is (0.7)=(0.5/0.71). ETAF for a Special Landscape Area shall not exceed 1.0. ETAF for existing non-rehabilitated landscapes is 0.8.

"Guidelines" refers to the guidelines for Implementation of this Article, as adopted by the City, which describes procedures, calculations, and requirements for landscape projects subject to this Article. The Guidelines are consistent with the regional Orange County Model Ordinance and Guidelines.

"Landscaped area" means all the planting areas, turf areas, and water features in a landscape design plan subject to the Maximum Applied Water Allowance and Estimated Applied Water Use calculations. The landscaped area does not include footprints of buildings or structures, sidewalks, driveways, parking lots, decks, patios, gravel or stone walks, other pervious or non-pervious hardscapes, and other non-irrigated areas designated for non-development (e.g., open spaces and existing native vegetation).

"Landscape Documentation Package" means the package of documents that a project applicant is required to submit pursuant to section 2.1 of the Guidelines.

"Landscape Installation Certificate of Completion" means the certificate included as exhibit E of the Guidelines that must be submitted to the City pursuant to section 2.7(C) thereof.

"Landscape project" means total area of landscape in a project, as provided in the definition of "landscaped area," meeting the requirements under Section 41-1501 of this Code.

"Maximum Applied Water Allowance" or "MAWA" means the upper limit of annual applied water for the established landscaped area as specified in section 2.2 of the Guidelines. It is based upon the area's reference evapotranspiration, the ETAF, and the size of the landscaped area. The Estimated Applied Water Use shall not exceed the Maximum Applied Water Allowance.

"Mined-land reclamation projects" means any surface mining operation with a reclamation plan approved in accordance with the Surface Mining and Reclamation Act of 1975.

"New construction" means, for the purposes of this Article, a new building with a landscape or other new landscape such as a park, playground, or greenbelt without an associated building.

"Permit" means an authorizing document issued by local agencies for new construction or rehabilitated landscape.

"Rehabilitated landscape" means any re-landscaping project that requires a permit, plan check, or development review and meets the applicability criteria of the Guidelines where the modified landscape area is greater than two thousand five hundred (2,500) square feet.

"Synthetic Turf" means an acceptable no mow ground cover made of synthetic, non-living material which meets the criteria standards set forth in the City's Design and Development Standards.

"Turf" means a ground cover surface of mowed grass or synthetic turf which meets or exceeds the standards set forth in the Guidelines. Annual bluegrass, Kentucky bluegrass, Perennial ryegrass, Red fescue, and Tall fescue are cool-season grasses. Bermuda grass, Kikuyu grass, Seashore Paspalum, St. Augustine grass, Zoysia grass, Buffalo grass, Mexican Feather grass, Muhly grass, and Sedge grass are warm-season grasses.

"Water Efficient Landscape Ordinance" means Ordinance No. NS-2891, adopted by the City Council on January 19, 2016 (first reading), and codified in the Municipal Code in Chapter 41Sections 1500—1504.

(Ord. No. NS-2891, § 2, 2-2-16)
