California’s Turf Ordinance Updates

07.05.2017 | Category, News

The California Department of Water Resources has placed new regulations in the state’s Model Water Efficient Landscape Ordinance due to the drought in the past years. Some major changes include landscape size threshold for new development projects which are greatly reduced from 5,000 square feet to 500 square feet. The maximum amount of water that may be applied to a landscape has decreased from 70% of the reference evapotranspiration (ETo) to 55% for residential and 45% for non-residential projects. The ordinance also states prescriptive requirements that may be used as a compliance option. Some which include installing “climate adapted plants that require occasional, little or no summer water.”

Kurapia is an evergreen low water ground cover that can be used as an alternative for other forms turf, meaning it is not subject to the restrictions of the Ordinance. It also meets the requirements for the evapotranspiration capacity, as it is 20% of the reference ETo. The plant species Phyla Nodiflora, which Kurapia’s species originated from, is registered in the WUCOLS IV Plant List as a low water plant with a Plant Factor of 0.1-0.3, while general turf grass has a Plant Factor of 0.8.
