This report is in addition to my report dated April 9, 2023 for this property, and is valid for a one-year time frame. Methods used to determine tree location and tree health: Tree diameter was measured with a forester’s tape. Tree dripline and height and other target distances were measured with a Nikon Pro laser range finder or tape shown in Figures 1 & 2. Trees are tagged with pink ribbon and Dymo Rhino aluminum labeler numerical impression in Figure 3. All measurements and notes are recorded in digital format on site. Forest Metrix software is used to record the data and pictures to help illustrate the findings, see Site Map and Tree Assessment Matrix photos.

Trees are indicated on the site with pink ribbon and numerical indications. There is no development occurring at this property. This is an established residential lot. Per RMC 4-4-130 “tree credit requirements shall apply at a minimum rate of thirty (30) credits per net acre.” This lot of 9,750 square feet would be considered 0.22 square acres. 30 x 0.22 = 6.6, rounded up = 7 tree credit requirements The remaining trees on this property of 6 caliper inches or greater are listed in Table 2 below. The remaining trees would more than satisfy the seven tree credit requirement per the chart in Table 3.
