The Land Evaluation and Site Assessment (LESA) Model is a point-based approach for rating the relative importance of agricultural land resources based upon specific measurable features.
The California LESA Model was developed to provide lead agencies with an optional methodology to ensure that potentially significant effects on the environment of agricultural land conversions are quantitatively and consistently considered in the environmental review process (Public Resources Code Section 21095), including in California Environmental Quality Act (CEQA) reviews.
The California Agricultural LESA Model evaluates measures of soil resource quality, a given project’s size, water resource availability, surrounding agricultural lands, and surrounding protected resource lands. For a given project, the factors are rated, weighted, and combined, resulting in a single numeric score. The project score becomes the basis for making a determination of a project’s potential significance.
The LESA Manual, produced in 1997, provides detailed instructions on how to utilize the California LESA Model, and includes worksheets for applying the Model to specific projects. The Manual is available for download. The following documents below are now available via email request at the links below:
