How large must an existing landscape be to require a MWELO permit for rehabilitation?

To require a Model Water Efficient Landscape Ordinance (MWELO) permit for rehabilitation, an existing landscape must be at least 2,500 square feet. This regulation aims to promote efficient water use in landscaping, especially important in drought-prone areas like California.

As landscapes increase in size, the potential impact on water resources also grows. The 2,500 square feet threshold reflects the need for oversight and standards to ensure water conservation practices are implemented in larger garden spaces while balancing practical considerations for smaller landscapes that might not have the same level of resource demand. This threshold helps target more significant contributors to water use without overburdening smaller projects with regulatory requirements.

Understanding this requirement is essential for landscape architects and professionals who are involved in rehabilitation projects, allowing them to plan accordingly to meet state regulations.
