92 WATER EFFICIENT LANDSCAPING AND CONSERVATION STANDARDS
ACTIVE RECREATION AREA: | Dedicated active play areas where irrigated lawn is used as the playing surface, such as a sports field designed for public use. Active recreation areas shall be: 1. A minimum of one thousand five hundred (1,500) contiguous square feet of lawn area. 2. Not less than thirty (30) feet in dimension. 3. Not less than ten (10) feet from areas dedicated to vehicular use, such as a street or parking lot. 4. Designed and located to be accessible to large populations, such as at a school, daycare, recreation center, senior center, public park, private park, water park or religious institution. 5. Co-located with amenities, including but not limited to trash bins, benches, tables, walking paths, drinking water, playground equipment and/or other recreational amenities. |
CONTROLLER: | A device used in irrigation systems to automatically control when and how long sprinklers or drip irrigation systems operate. |
DRIP IRRIGATION: | An irrigation system that delivers water by adding water at the plant’s base and root zone, usually measured in gallons per hour. Drip irrigation exhibits a droplet, trickle, umbrella or short stream pattern, to reduce evaporation, overspray, and water use, and improving water conservation. |
DRIP EMITTER: | A drip irrigation fitting that delivers water slowly at the root zone of the plant, usually measured in gallons per hour. |
GRADING PLAN: | The grading plan shows all finish grades, spot elevations, drainage as necessary, and new and existing contours with the developed landscaped area. |
GROUND COVER: | Material planted in such a way as to form a continuous cover over ground that can be maintained at a height no more than twelve inches (12"). |
HARDSCAPE: | Elements of landscape constructed from non-living materials such as concrete, boulders, brick, blacktop, and lumber. Includes patios, decks, and paths, but does not include driveways and sidewalks. |
HYDROZONE: | Portion of landscape area having plants with similar water needs and rooting depth. A hydrozone may be irrigated or non-irrigated. |
IRRIGATION PLAN: | A plan that shows the components of the irrigation system with water meter size, backflow prevention, precipitation rates, flow rate, and operating pressure for each irrigation circuit, and identification of all irrigation equipment. |
IRRIGATION RUNOFF: | Irrigation water that is not absorbed by the soil or landscape area to which it is applied, and that flows onto other areas. |
LANDSCAPE ARCHITECT: | A person who holds a professional license to practice landscape architecture in the state of Utah. Pursuant to Utah Code, licensed landscape architects, licensed architects, licensed land surveyors, and licensed engineers can professionally stamp plans that fall under the practice of landscape architecture. This includes commercial landscape and irrigation plans. |
LANDSCAPE AREA: | Area of a Lot not including any building footprints, driveways, sidewalks, and patios; also not including areas of agricultural, horticultural, or gardening uses which are permitted by applicable zoning. |
LANDSCAPE DESIGNER: | A person who may or may not hold professional certificates for landscape design/architecture, and who generally focuses on residential design and horticultural needs of home landscapes. Landscape designers may assist developers and property owners with landscape design but may not submit landscape plans for multifamily residential or nonresidential properties and projects under this chapter unless certified by a landscape architect. |
LANDSCAPE DOCUMENTATION PACKAGE: | The documentation of graphic and written criteria, specifications, and detailed plans to arrange and modify the effects of natural features to comply with the provisions of this chapter. The Landscape Documentation Package must include a project data sheet, a site plan, a planting plan, an irrigation plan, construction details, and a grading plan. |
LANDSCAPE OR LANDSCAPING: | Any combination of berms; living plants, such as trees, shrubs, vines, ground cover, annuals, perennials, ornamental grass, or seeding; natural features such as rock, stone, or bark chips; and structural features, including but not limited to, fountains, reflecting pools, outdoor artwork, screen walls, fences, or benches that create an attractive and pleasing environment. |
LANDSCAPE OR LANDSCAPING MAINTENANCE: | Maintaining or keeping any landscaping, or any area required to be landscaped: |
A. In a live and thriving condition, with consideration for normal growth and water needs; and | |
B. Fertilized, mowed, trimmed, edged, mulched and free from weeds, dead plants, litter, refuse, or debris in compliance with regionally accepted horticultural practice and city ordinances. | |
LANDSCAPE PLAN: | A plan that clearly and accurately identifies the location and species of new and existing trees, shrubs, ground cover, and other plants on a site, and any other landscape element, and includes an irrigation plan. |
LAWN: | Irrigated nonagricultural land planted in closely mowed, managed grasses. |
MULCH: | Material (such as, but not limited to, rock, bark, wood chips) uniformly applied upon the surface of the soil to reduce evaporation and weed growth. Mulches must allow penetration of water and air. For purposes of these standards, ungrouted pavers, stepping stones and artificial turf manufactured to be permeable to air and water may be considered mulch. |
MULTIFAMILY: | Any residential use comprised of a dwelling or dwellings designed for occupation by more than one family in any zone, but for purposes of this Chapter, excludes single-family dwellings, two-family dwellings, dwellings containing an approved internal accessory dwelling unit, or dwellings which are an approved accessory dwelling unit to a primary dwelling. |
PARK STRIP: | A typically narrow landscaped area located between the back-of-curb and sidewalk. |
PLANTING BED: | Areas of the landscape that consist of plants, such as trees, ornamental grasses, shrubs, perennials, and other regionally appropriate plants. |
PLANTING PLAN: | A planting plan that clearly and accurately identifies the type, size, and locations for new and existing trees, shrubs, planting beds, ground cover, lawn areas, driveways, sidewalks, hardscape features, and fences. |
PRECIPITATION RATE: | The depth of water applied to a given area, usually measured in inches per hour. |
PRESSURE REGULATING VALVE: | A valve installed in an irrigation mainline that reduces a higher supply pressure at the inlet down to a regulated lower pressure at the outlet. |
REHABILITATED LANDSCAPE: | Landscape area in which over fifty percent (50%) of existing landscaping is removed and replaced. Includes all landscaping funded in part, or completely, by Washington County Water Conservancy District’s landscape conversion program. |
SECONDARY IRRIGATION WATER: | Non-potable water that is untreated and used for irrigation of outdoor landscaping. |
SINGLE FAMILY: | Any residential use comprised of a dwelling designed for occupation by only one family in any zone, and for purposes of this Chapter includes primary dwellings, dwellings containing an approved internal accessory dwelling unit, and approved accessory dwelling units. |
SLOPE: | A vertical rise in feet measured over a horizontal distance, expressed as a percentage, measured generally at right angles to contour lines. |
TWO-FAMILY: | Any residential use comprised of a dwelling designed for occupation by two families in any zone, but for purposes of this Chapter excludes dwellings containing an approved internal accessory dwelling unit, or dwellings which are an approved accessory dwelling unit to a primary dwelling. |
WATER-CONSERVING PLANT: | A plant that can generally survive with available rainfall once established, with possible supplemental irrigation needed or desirable during spring and summer months or during drought periods. (Ord. 2024-02: Ord. 2022-05) |
