What type of grass is prohibited on slopes of 4:1 or greater according to MWELO?

• A. All types of grass
• B. Only native grasses
• C. Any turf grass
• D. Ornamental grasses

Answer: (C)

The prohibition of turf grass on slopes of 4:1 or greater as specified by the Model Water Efficient Landscape Ordinance (MWELO) aims to promote water conservation, reduce maintenance needs, and prevent erosion. Turf grasses typically have high water requirements, which can be unsustainable in California's climate, especially in areas that are prone to erosion or runoff. When turf grass is planted on steep slopes, it can lead to increased water usage as well as the need for more frequent irrigation, which contributes to water waste and may impair soil stability. In contrast, alternative landscaping practices, such as using drought-resistant native plants or ornamental grasses, are encouraged as they typically require less water and help maintain soil integrity. Thus, the correct answer focuses on the specific restrictions around any turf grass to emphasize sustainable landscape practices on steep inclines.
