Which scenario triggers the requirements of MWELO?

The scenario that triggers the requirements of the Model Water Efficiency Landscape Ordinance (MWELO) pertains to new construction projects that incorporate more than 500 square feet of landscape area. MWELO was established to promote water conservation and efficient landscape management, especially in light of California's diverse climate and varying water availability.

When new construction projects exceed the stated threshold, they must adhere to specific landscape design criteria, irrigation efficiency standards, and other requirements aimed at minimizing water use. This ensures that new developments contribute to the sustainability efforts within California's landscape architecture practices.

For other options, while large landscape projects and certain activities in gardening can have guidelines, they do not specifically tie back to MWELO's crucial trigger points, which are primarily focused on new construction landscapes over 500 square feet to enforce efficient water usage from the outset.
