7.7. Native Plant Preservation
The NPPO is intended to encourage preservation in place of healthy native plants through sensitive site design that minimizes the disruption of areas within the site containing healthy plants while allowing for salvage and transplanting plants on the site that are likely to survived.

An approved Native Plant Preservation Plan Sections 7.7.4 is required in accordance with Sections 7.7.3.D.3 & .4 of the Unified Development Code (UDC) and Admin. Manual Section 2-11.0.0 is required prior to Grading Plan approval.

By far, the easiest method of meeting this requirement is to leave 30% undisturbed natural open space (NUOS).
