Section 9.13   Landscaping
   (1)   The following provisions apply to both residential and nonresidential zoning districts.
      (A)   No zoning clearance or building permit shall be issued until a landscape plan has been approved by the Zoning Administrator. The Zoning Administrator may waive the requirement of a landscape plan if the project does not contain any site disturbance or is deemed to be a minor modification.
      (B)   With the exception of removal of packrat nests and pruning of diseased or dead tree limbs, no area on a subject lot or parcel, other than the disturbed area (development envelope) prescribed in Article VI, Section 6.01 shall be disturbed. In order to preserve the desert character and identity of the community, only native desert vegetation shall be maintained within the required yards (building setbacks). Non native plant/tree/cacti (excluding drought tolerant and/or desert hybrid) species are prohibited in the required yards. The application of pre-emergence, grubbing, thinning or trimming of vegetation shall be limited to the disturbed area. Protected plants shall not be damaged, destroyed, or removed from any portion of a lot or parcel unless deemed not salvageable on an approved landscape plan in association with a building permit. During the site development phase, salvaged protected plants shall be placed in a designated nursery and irrigated area until site work is completed. Once site work is completed and landscaping has begun, subject plants shall be transplanted within disturbed areas or alternative areas approved by the Zoning Administrator. (Ord. #2007-05)
      (C)   If the Zoning Administrator interprets that a portion of the required yard contains a collection of decaying plant material that is susceptible to wildfires, that portion of material which presents a detriment to public health, safety and welfare shall be removed by the property owner. Additionally, vegetation within a thirty (30) foot fire suppressant buffer consistent with the Town’s fire provider requirements may be thinned and trimmed around buildings to better secure the structure from wildfires. Protected plants shall include: (Ord. #2007-05)
         1)   Yucca.
         2)   Ocotillo.
         3)   All members of the cactus family with the exception of Cholla and Prickly Pear.
         4)   Protected trees that are four (4) inches or greater in caliper measured one (1) foot above native grade.

      (D)   Protected plants shall not be damaged, destroyed, or removed from any portion of a lot or parcel unless deemed not salvageable on an approved landscape plan in association with a building permit. During the site development phase, salvaged protected plants shall be placed in a designated irrigated nursery area until site work is completed. Once site work is completed and landscaping has begun, subject plants shall be transplanted within the disturbed area or alternate areas of the lot approved by the Zoning Administrator.
