A. A Native Plant Inventory containing the following elements:
1. All Viable Protected Native Plants shall be tagged with an embossed metal, or approved equal, inventory number. Tagging is not required in those areas that are to remain undisturbed. If the sampling method is used to estimate Protected Native Plants, only the Protected Native Plants required to be either Preserved in Place (PIP) or Transplanted on Site (TOS) shall be tagged;
2. A list of all Protected Native Plants as designated in Section 5-02.0.0, Protected Native Plant List, of the Technical Standards Manual located on the site including all Saguaros; all trees with a caliper of at least four inches measured at six inches for single-trunked specimens and 12 inches for multitrunked specimens above grade level at the base of the tree, per Section 11.4.4, Definitions - C, of the UDC; all shrubs equal to or greater than three feet in height; all succulents equal to two feet in height or greater; and all cacti. The list shall include the identification number, genus and species, and size. If the Plant Inventory Methodology is chosen, then the Native Plant Viability and Transplantability Status (see Section 2-115.4.2) of all Protected Native Plants on the site shall be listed. If the Plant Appraisal Methodology is chosen, then the appraisal value of each plant removed from the site shall be listed;
3. An aerial photograph, taken within a maximum of three years of submittal, at a minimum scale of one inch equals 60 feet showing the site’s boundaries, the locations of all Protected Native Plants within those boundaries, and the plants’ identification numbers keyed to the inventory list in Section 2-11.4.1.A.2. Any aerial photograph submitted, which was taken more than one year prior to submittal, shall be accompanied by a letter stating that the site is substantially unchanged from the date of the aerial photograph;
4. Areas of the site containing communities of Protected Native Plants with a low plant viability rating (as in the case of plants damaged by fire, frost, flood, insects, disease, or other natural damage) may be evaluated as a group without inventory. These areas shall be clearly delineated and annotated on the aerial photograph inventory map;
5. Areas of the site may be sampled to estimate representative numbers of Protected Native Plants. These sampling techniques can be applied to any of the methodologies chosen to comply with the ordinance. Areas of the site must be inventoried by sampling typical identifiable areas for each genus and species and estimating representative plant numbers per square acre of the total site area. The samples must be representative of the Viable species found on-site and shall not be less than 20% of the total site. If various plant associations (upland, riparian, xeroriparian, etc.) are found on one site, then a sample of not less than 20% of each defined plant association, by its respective site area, shall be inventoried. Under any methodology, Ironwoods and Saguaros shall be inventoried individually and not by sampling. Staff reserves the right to reject sampling to establish an inventory of plant counts, on a case-by-case basis; and,
6. Sites that use the sampling method for inventory of Protected Native Plants will require field tagging of those plants to be PIP or TOS. All PIP plants must be identified on the aerial photo and must be tagged, flagged, and fenced. In a summary, the total number of plants, by genus and species, that must be PIP or TOS and the required mitigation numbers shall be listed. This summary shall be located on the NPPO plan and any associated Landscape/Mitigation Plan. Protected Native Plants to be TOS may be identified individually or in a “pool count.” The “pool count,” or total number of required TOS Protected Native Plants, shall match the totals in the summary and may vary according to field conditions; and therefore, final selection will be that of the “plant professional” and the salvage contractor. Once the total number of plants to be TOS, by genus and species from the summary, has been identified in the field, they must be tagged and flagged for TOS. Plants within a designated Natural Undisturbed Open Space (NUOS) area, under any method, do not require individual tagging or flagging since their boundaries will be fenced.
