<br />Re.: Tree management
<br />Site: Dublin Canyon Rd., north of Laurel Creek Dr.
<br />City of Pleasanton File No.: P20-0549
<br />
<br />Mr. Psefteas;
<br />
<br />I am writing in response to a request from your representative, Guy Houston, for an update to my previous
<br />information on trees at this site, in order to comply with the requirements of the City of Pleasanton1. Specifically,
<br />to comply with comments relative to an arborist report cited in a letter from the City entitled “Subject: P20-0549
<br />Preliminary Review Application”, Jennifer Hagen, Associate Planner, dated June 24, 2020.
<br />
<br />Mr. Houston provided me revised site and grading plans, and we2 inspected the trees on August 27, 2020. This
<br />was the most recent of several inspections and resulting reports, beginning in 2015, for Guy Houston. The tree
<br />data from 2015 is outdated as a revised tree appraisal methodology is in practice3 and required by the City of
<br />Pleasanton. The site use and plans have also been significantly revised. This report incorporates all updated
<br />data, evaluations and appraisal values.
<br />
<br />Nine trees not previously included due to their small size, have grown to larger than the minimum 6” diameter
<br />(DBH)A, and some, which were grouped together in 2015, are individually listed in this report. These trees were
<br />assigned new tag numbers (nos. 1-9). Many original numbered tags are engulfed by tree trunk growth, so all
<br />trees tagged in 2015 were re-tagged duplicating the original numbers.
<br />
<br />We tagged, measured (diameter & heightB), identified as to genus-species, evaluated, GPS-locatedC and
<br />photographed all trees within or adjacent to the immediate construction zone. The intent of my inspections, data
<br />collection, document reviews and this report is to assist with your tree protection planning during construction
<br />and with your compliance with the requirements of the City of Pleasanton1.
<br />
<br />SUMMARY: I identified 28 trees as being located within the construction zone. Ten additional trees are outside
<br />the construction zone in the Riparian Corridor. Of these 38 trees, 22 are Heritage trees as defined by the City of
<br />Pleasanton1 and thus require permitting and specific protection measures. I identified 30 trees to remove, due
<br />to either existing condition or conflict with construction, or both. Twenty-five trees are in direct conflict with
<br />construction plans. Eight trees, all Heritage Trees1, can be retained via implementation of the protective
<br />measures described in this report and as required by the City of Pleasanton1.
<br />
<br />I developed appraisal values for the subject trees employing methods developed by the Council of Tree and
<br />Landscape Appraisers (CTLA) and described in the publication, Council of Tree and Landscape Appraisers,
<br />2019, Guide for Plant Appraisal, Tenth Edition, Second Printing, International Society of Arboriculture. I
<br />selected the Cost Approach, Reproduction Method, Trunk Formula Technique as appropriate for the trees of this
<br />project. The total value for the 28 trees appraised is $138,300.00, which is an average value of $4,939.00. The
<br />remaining 10 trees (nos. A-J) were judged to be of no landscape amenity value and are outside the construction
<br />zone. However, they may well be worth retaining as wildlife habitat within the Riparian Corridor.
