Re Tree Addendum Correction
Dear Jessica,
Thank you for pointing out the error regarding the tree numbers for the trees in the Napa Project.
The tree numbers 2253, 2254, 2256, 2257, 2258, 2259, 2260, 2261 and 2262, included in your email of yesterday, are correct as I verified on site today. These are all cultivars of red oak.
Tree 2246 is redwood and 2255 is sweet gum, both of these are so listed in Appendix A. These numbers and the red oak species modification have the report in proper listings.
Thank you for the opportunity to continuing to work with you on this project.

Re: Tree inventory addendum
Dear Jessica:
As you requested, the trees growing along your north property line have been inventoried and tagged. All the trees are either growing with the fence included in their trunks or immediately adjacent to the fence on the adjacent property and the project property. Management and or removal of these trees will not impact the adjacent regulated redwoods. Below is the table of these trees.

In response to your sage comment regarding the trees along the walkway that you identified as possibly oak trees. Now that they are leafed out, they appear to be red oak.
They are infested
with mildew. These trees are numbers 567,568, 569, 570, 574 and 576. Due to the close proximity to adjacent trees, I recommend they not be considered for transplanting.

Re: 2344 Old Sonoma Road, Napa
Dear Jessica:
Thank you for the opportunity to prepare the attached Tree Inventory for 2344 Old Sonoma Road in Napa. The report identifies the regulated trees as specified in the City of Napa Tree Ordinance. Chapter 12.45 addresses “Trees on Private Property” which are identified in my attached report as “regulated trees”. In addition to those trees and in response to your comment that you want trees on the property, I inventoried added landscape trees including non -native smaller trees for your reference in the planning process. Again, these are for your reference only. Please note that because we were on site in January, these landscape trees were dormant and it was difficult to specifically identify the species.
Many of the redwood trees (regulated) are located adjacent to the existing structures.
Special attention must directed to avoid potential impacts on the roots since redwood is relatively shallow rooted especially in the high clay soils on the site. I recommend close monitoring to prevent root damage.
Please keep me informed on planning and how I may participate. Should you or others have questions or comments, please contact me at your convenience. If site meetings are required, I will be pleased to meet your schedules. A hard copy is also being sent to you.
Respectfully,
Ralph Osterling, President, ACF, CLFA

INTRODUCTION
On January 28, 2022 and January 30, 2022, Ralph Osterling Consultants, Inc. (ROC) completed a tree inventory of the 2344 Old Sonoma Road site. The 8.3 acre site is chain link fenced to secure previously developed buildings consisting of three historic structures and numerous modular units. The site has been landscaped and now the landscape improvements are abandoned. The purpose of this tree inventory is to meet the permit process and to provide Heritage Housing Partners the locations and conditions of native trees as defined in Chapter 12.45 of the City of Napa Municipal Code (Tree Ordinance). In addition to the trees identified in the Tree Ordinance, landscape trees were included for reference only in the plan development process. Many of these dormant landscape trees display deferred maintenance with off balance crowns and unsafe branching.
City of Napa
The City of Napa recognizes the value of healthy trees to create an urban forest in the community. This healthy for est provides scenic beauty, improved quality of life and improved property values. In Chapter 12.45 the Tree Ordinance identifies the following trees within the City as shown in Table 1 – City of Napa Tree Ordinance Species Tree Listing.
TABLE 1 - CITY OF NAPA TREE ORDINANCE
SPECIES DBH (Inches)
Valley Oak (Quercus lobata) 12 inches or greater
Coast Live Oak (Quercus agrifolia) 12 inches or greater Black Oak (Quercus kelloggii) 12 inches or greater
Blue Oak (Quercus douglasii) 6 inches or greater
Coast Redwood (Sequoia sempervirens) 36 inches or greater California Bay (Umbellularia californica) 12 inches or greater Black Walnut (Juglans hindsii) 12 inches or greater
These protected trees are subject to regulation for removal, pruning, and development disturbance including the below impacts. The only regulated trees on the project site are 1 coast live oak and 18 coast redwood. The remaining listed trees are not subject to the Tree Ordinance as shown in Table 2 – On Site Ordinance Trees.

All trees identified are tagged using red sequentially numbered metal tags and flagged for ready locations for the surveyors and others. All trees included in the survey were measured at dbh (4.5 feet above ground) and the di ameters recorded.
Conditions of trees were identified and recorded as shown in Table 2 – On Site Ordinance Trees.

INVENTORY METHODS
The inventory was completed by ROC, beginning at the southwest corner of the property adjacent to the loop driveway road intersection with Old Sonoma Road. All identified trees were tagged with red sequentially numbered metal tags. Red flagging secured t o the tag nails. Trees over 9 inches in diameter are identified and tagged for reference. In addition to the dbh, health, overall condition, and structure, the crown diameters were estimated.
The ratings for tree inventory are listed below as shown in Ta ble 3 – Rating Definitions.

Fair Trunk, limb and branch development though flawed is typical of this species.
Good Trunk is well developed with well-attached limbs and branches have some flaws but hardly visible.
Very Good In addition to attributes of a good rating, the tree exhibits a well- developed root flare and a balanced canopy.
HEALTH Definition

The inventory was completed on January 30, 2022, during the dormant period of most landscape trees. Hence, these landscape species are not all specifically identified, only included for reference.
Results
A total of 86 trees were identified, tagged and evaluated. Of the 86 total, 19 are subject to the Tree Ordinance. The ordinance trees included 1 coast live oak (Quercus agrifolia) and 18 coast redwood ( Sequoia sempervirens) . All of the regulated trees, except for two redwoods are in good or fair condition.
RECOMMENDATIONS
At the time of the field inventory, the ordinance trees that might be removed or impacted were not determined. Tree protection measures must be included on the approved site plans and installed prior to any site grading or cleari ng. Tree protection measures shall include orange protection fencing securely attached to steel T -drive posts firmly driven in to the ground on 6 foot centers at or near the limits of the driplines. This protection fencing will be inspected by ROC and approved and confirmed in writing. The fencing shall be installed around the entire clumps of redwoods. The fencing shall remain effective through the entire project construction process. If the fence is damaged, it shall be reported to ROC and repaired immediately. Several of the redwoods are located adjacent to the modular buildings where equipment operations should be subject to monitoring by ROC. In the grading and site preparation work, any regulated tree roots over 3 inches in diameter shall be cle an cut and not exposed to drying. Exposed roots shall be kept moist with wet fabric or mulch. Should tree crown pruning be required for clearances, it shall be completed by a qualified contractor under the direct supervision of ROC.
