Clearing or removal of vegetation (trees, shrubs, etc.) is prohibited in an NGPA/CAPA without a permit issued by Planning and Development Services (PDS). There are exceptions in County Code that does allow for the removal and/or control of invasive species (blackberry, English ivy, etc.) within an NGPA/CAPA. Invasive species control must follow accepted best management practices for control of the species. Additionally, erosion must be controlled, and the areas cleared of invasive species need to be replanted with species suited for the site conditions (sun exposure, soil type, hydrology, etc.).
