What is NPPO?

The Native Plant Preservation Ordinance is a building code that protects vegetation in upland (usually non-riparian) areas of a site. The NPPO requires preservation of vegetation meeting species, caliper, and viability criteria.

A Native Plant Preservation Plan (NPPP) is required by county and state development services when the total area of the existing and the proposed disturbance/grading on any lot exceeds 14,000 square feet, the total lot area is larger than 36,000 square feet, or if required by a subdivision plat.
