What is the Model Water Efficient Landscape Ordinance (MWELO), and how does it affect my project?

As licensed Landscape Architects in California, we will help clarify the Model Water Efficient Landscape Ordinance (MWELO) and its implications for your project. MWELO, mandated by local agencies, emphasizes water-efficient landscaping practices tailored to each region’s water budget. Our expertise lies in crafting landscape designs that adhere to MWELO standards, incorporating regionally suitable plant selections and efficient irrigation systems. We handle the intricate process of preparing and submitting the required documentation to local agencies for approval, ensuring your project aligns with regulatory requirements and contributes to sustainable water management practices.

Construction Administration & Observation

CA&O is an important service to ensure the project gets built per plan.  Involvement during construction allows us a chance to make any necessary adjustments based on unforeseen or field conditions. Often the CA&O scope is overlooked, and this leads to the contractor making design decisions. When a discrepancy or unforeseen condition arises, we can work with the contractor and client to provide a solution to ensure the design intent remains in place and the construction schedule does not get held up.

We review submittals for the various plant materials to ensure that upon installation, they are healthy and up to par with industry standards and client expectations.
