According to the Model Water Efficient Landscape Ordinance, turf is not permitted on slopes greater than what percentage?

The Model Water Efficient Landscape Ordinance sets specific guidelines to promote water conservation and sustainable landscaping practices, particularly in regions where water scarcity is a concern. When it comes to managing slopes, the ordinance establishes a maximum percentage for turf to mitigate erosion, reduce water runoff, and ensure that maintenance practices are feasible.

A slope greater than 25 percent is typically considered too steep for turf grass, as maintaining such an area can be challenging. Turf on steep slopes can lead to increased rates of erosion, water loss, and difficulties in mowing and upkeep. Therefore, the ordinance restricts the use of turf on slopes exceeding this percentage to promote more sustainable landscaping options, such as drought-resistant plants or ground covers that are better adapted to handle the conditions while minimizing water usage.

This approach aligns with broader environmental goals of conserving resources and promoting resilient landscapes that are appropriate for local conditions. Thus, recognizing the 25 percent threshold helps landscape professionals make informed choices that adhere to both practical and regulatory standards in landscape design and maintenance.
