What is the area threshold for a new landscape construction project to require compliance with the Model Water Efficient Landscape Ordinance?

The Model Water Efficient Landscape Ordinance (MWELO) is designed to promote efficient use of water in landscape projects. The area threshold that triggers the need for compliance with this ordinance is crucial for promoting sustainable landscaping practices.

For new landscape construction projects, the threshold is set at 500 square feet. This means that any project involving landscaping that covers an area of 500 square feet or more must adhere to the standards and guidelines laid out in the MWELO. By setting this threshold, the ordinance aims to ensure that larger projects, which can have a significant impact on water consumption, implement water-efficient practices, thus conserving water resources.

Lower thresholds would risk excluding larger areas that contribute to significant water use, while higher thresholds could lead to less efficient landscape practices in larger projects. Therefore, the figure is strategically chosen to apply to projects that are likely to have a more substantial effect on water consumption and landscape sustainability.
