La Verne City Zoning Code

CHAPTER 18

118 WATER EFFICIENT LANDSCAPES

§ 18.118.010 Purpose.

The purpose of this chapter is to establish water efficient landscape regulations that are at least as effective in conserving water as the State Model Water Efficient Landscape Ordinance, in the context of conditions in the city, in order to ensure that landscapes are planned, designed, installed, maintained, and managed in a manner that uses water efficiently, encourages water conservation, and prevents water waste. The provisions of this chapter shall be deemed to be controlling over the subject matter herein in the event of any conflict between this chapter and any other provision in the municipal code.
(Ord. 1065 § 2, 2016)

§ 18.118.020 Definitions.

For the purposes of this chapter and the Guidelines for Implementation of this chapter, the following terms are defined:
"City"
means the city of La Verne.
"City manager"
means the city manager of the city of La Verne or designee.
"Applicant"
means the person submitting a landscape documentation package. Applicants can be the property owner or designee.
"Applied water"
means the portion of water supplied by the irrigation system to the landscape.
"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 average annual total amount of water estimated to be necessary to keep plants in a healthy state, calculated as provided in the Guidelines. It is based on the reference evapotranspiration rate, the size of the landscape area, plant water use factors, and the relative irrigation efficiency of the irrigation system.
"Evapotranspiration adjustment factor or ET adjustment factor or ETAF"
is equal to the plant factor divided by the irrigation efficiency factor for a landscape project, as described in the Guidelines. The ETAF is calculated in the context of local reference evapotranspiration, using site-specific plant factors and irrigation efficiency factors that influence the amount of water that needs to be applied to the specific landscaped area. Residential areas shall not have an ETAF that exceeds 0.55 and commercial areas must not exceed 0.45. The ETAF for a special landscaped area shall not exceed 1.0.
"Guidelines"
refers to the Guidelines for Implementation of the Water Efficient Landscape Ordinance, as approved by the city, which describes procedures, calculations, and requirements for landscape projects subject to this chapter.
"Hydrozone"
means a portion of the landscaped area having plants with similar water needs and typically irrigated by one valve/controller station. A hydrozone may be irrigated or non-irrigated.
"Irrigation efficiency or IE"
means the measurement of the amount of water beneficially used divided by the amount of water applied to the landscaped area. Irrigation efficiency is derived from measurements and estimates of irrigation system characteristics and management practices. The irrigation efficiency, for purposes of this chapter, are defined in Section 3.3(N) of the 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 documents required to be provided to the city for review and approval of landscape projects subject to this chapter, as described in the Guidelines.
"Landscape professional"
means a licensed landscape architect, licensed landscape contractor, or any other person authorized to design a landscape pursuant to Sections 5500.1, 5615, 5641, 5641.1, 5641.2, 5641.3, 5641.4, 5641.5, 5641.6, 6701 and 7027.5 of the California Business and Professions Code, Section 832.27 of Title 16 of the California Code of Regulations, and Section 6721 of the California Food and Agriculture Code.
"Landscape project"
means total area of landscape in a project, as provided in the definition of "landscaped area," meeting the requirements under Section 18.118.030 of this chapter.
"Landscape rehabilitation"
means any re-landscaping project that meets the applicability criteria of Section 18.118.030(A) of this chapter, where the modified landscape area is greater than two thousand five hundred square feet or where the cumulative modified area is greater than two thousand five hundred square feet if the modifications are planned to occur incrementally within one year.
"Local agency"
means a city or county, including a charter city or charter county, or local water purveyor that is authorized by the city to implement, administer, and/or enforce any of the provisions of this chapter on behalf of the city. The local agency may be responsible for the enforcement or delegation of enforcement of this chapter including, but not limited to, design review, plan check, issuance of permits, and inspection of a landscape project.
"Local water purveyor"
means any entity, including a city, county, public agency, or private water company that provides retail water service. Local water purveyor shall also mean any entity that provides wholesale water service.
"Maximum applied water allowance or MAWA"
means the upper limit of annual applied water for the landscaped area as specified in Section 3.0 of the Guidelines. It is based upon the area's reference evapotranspiration, the ET adjustment factor, and the size of the landscaped area. The estimated applied water use shall not exceed the MAWA.
"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 landscape"
means, for the purposes of this chapter, 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 a local agency for new construction or rehabilitated landscape.
"Person"
means any individual, firm, joint venture, joint stock company, partnership, public or private association, company, corporation, business trust, organization, public or private agency, government agency or institution, school district, college, university, any other user of water provided by the local water purveyor, or the manager, agent, officer, or employee thereof, or any other entity which is recognized by law as the subject of rights or duties.
"Plant factor or plant water use factor"
is a factor, when multiplied by ETo, that estimates the amount of water needed by plants. For purposes of this chapter, the plant factor range for very low water use plants is 0 to 0.1; the plant factor range for low water use plants is 0.1 to 0.3; the plant factor range for moderate water use plants is 0.4 to 0.6; and the plant factor range for high water use plants is 0.7 to 1.0. Plant factors cited in this chapter are derived from the Department of Water Resources 2000 publication "Water Use Classification of Landscape Species."
"Reference evapotranspiration or ETo"
means a standard measurement of environmental parameters which affect the water use of plants. ETo is given expressed in inches per day, month, or year as represented in the Guidelines, 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.
"Turf"
means a groundcover surface of mowed grass. Annual bluegrass, Kentucky bluegrass, Perennial ryegrass, Red fescue, and Tall fescue are cool-season grasses. Bermuda grass, Kikuyugrass, Seashore Paspalum, St. Augustinegrass, Zoysiagrass, and Buffalo grass are warm-season grasses.
"Valve"
means a device used to control the flow of water in an irrigation system.
"Water feature"
means a design element where open water performs an aesthetic or recreational function. Water features include ponds, lakes, waterfalls, fountains, artificial streams, spas, and swimming pools (where water is artificially supplied). The surface area of water features is included in the high water use hydrozone of the landscaped area. Constructed wetlands used for on-site wastewater treatment, habitat protection or stormwater best management practices that are not irrigated and used solely for water treatment or stormwater retention are not water features and, therefore, are not subject to the water budget calculation.
