1 Agenda Item B.1 DISCUSSION/ACTION ITEM Meeting Date: June 18, 2014 TO: FROM: CONTACT: SUBJECT: Commissioners Rosemarie Gaglione, Interim Public Works Director Robert Morgenstern, Public Works Manager City Tree List and Planting Guidelines RECOMMENDATION: A. Review Revised Tree List & Planting Recommendations for the Goleta from City s Contract Arborist; and B. Direct staff to present the Commission s recommendations on the Approved St Tree List and Planting Guidelines to the City Council for adoption. BACKGROUND: On March 18, 2013, the City Council adopted the St Tree Planting List (latest revision from 2/11/09) and St Tree Subcommittee Planting Guidelines (latest revision 12/8/09) that was recommended by the City Arborist (then on staff) and the St Tree Subcommittee of the Design Review Board. DISCUSSION: The Council adopted Urban Forest Management Plan (UFMP) recommends in Section 4.4.2, that the City Consider revising the recommended st list to include all City sites and develop an inclusive species list to identify s eligible for planting in City areas. It has been over four years since the list has been reviewed and has never been reviewed by the newly formed Public Tree Advisory Commission (PTAC). The City s Contract Arborist, Mr. Bill Spiewak, was directed to review the current approved St Tree Planting List (Attachment 1) and St Tree Subcommittee Planting Guidelines (Attachment 2) and offer some recommended changes that would comply with the recommendations and goals of the UFMP. The report of his findings and recommendations are included as Attachment 3. The recommendations include:

2 Meeting Date: June 18, 2014 the deletion of eleven (11) s currently on the approved list; the addition of thirty-one (31) s to the list, and; periodic review of the approved list and planting guidelines. Once the Commission has decided which recommendations from Mr. Spiewak s report should be considered for implementation, staff will present the Commissions findings to the City Council for adoption.

11 REVISED TREE LIST & PLANTING RECOMMENDATIONS FOR THE CITY OF GOLETA Prepared for:!!!!!! Robert Morgenstern Public Works Manager - Goleta 130 Cremona Dr., Suite B! Goleta, California Prepared by: Bill Spiewak!!!!!!! Registered Consulting Arborist #381!! Board Certified Master Arborist #310B American Society of Consulting Arborists! International Society of Arboriculture!! 3517 San Jose Lane, Barbara, CA 93105!! (805) / bill@sbarborist.com!! April 30, 2014 SUMMARY The Urban Forest Management Plan for the Goleta states that s lists and planting recommendations should be periodically reviewed and revised as necessary. These documents were last revised in February 2009 prior to my involvement and approved by the City Council. As the Contract Arborist for the Goleta, I was assigned to once again review and revise the documents. When reviewing the Nursery and Planting Standards, I came across several items that warranted further discussion and inserted my comments into the document for further review by the St Tree Subcommittee. I also reviewed and revised the current st list. Based on my experience, research, and review of seven municipal lists and three reference books, I eliminated eleven s and added thirty-one s for a new list. I included more information on each and reclassified some into different planting categories. Although recommendations are based on planting site size, it is important to consider the site, the surrounding location, and the local needs prior to a final selection.

13 Goleta Tree List & Planting Guidelines: Revisions! Apr 30, 2014 BACKGROUND / ASSIGNMENT In March 2013, a discussion took place regarding the Goleta s Tree List and Planting Guidelines and the status of revisions. According to Goleta s Urban Forestry Management Plan, the list and guidelines warrant periodic review and revisions. I was assigned to undertake the task of reviewing the list and planting guidelines and preparing a report with my findings and recommendations. USE OF THIS REPORT It is my intention that this report be used to revise the current Goleta St Tree List and Planting Guidelines adopted by the City Council. LIMITS OF THIS REPORT There is variability in characteristics of s due to differences in climate, soil, and care. There is also variability in varieties of species that results in different characteristics as reported in some comparable lists. This report has looked at that variability among different regions and compared them to my local experiences where applicable. The list is limited to some of the most important characteristics of s that should be decided upon prior to selection. However, other elements such as allergens, fruit drop, crown density, color, soil characteristics, and growth rate, that are not included in this report, should be considered prior to selection. SCOPE OF WORK This project involved the following tasks: Review the planting guidelines and prepare recommendations for revisions; Review the Goleta St Tree list and prepare comments based on experience and research; Review planting lists from other Southern California cities and counties, the CalPoly Select Tree web site, and regional publications regarding st s; Assess what is recommended on the list, what has proven successful in Barbara County and what could be added. RECOMMENDED NURSERY & PLANTING STANDARDS (previously revised on 2/11/2009) I have included comments for further discussion regarding these standards at the end of this report. Most of these comments were based on contradictions within the document or criteria that was variable based on sizes. Bill Spiewak - Consulting Arborist! 3

14 Goleta Tree List & Planting Guidelines: Revisions! Apr 30, 2014 TREE LIST (previously revised on 2/11/2009) The recommendations on this list were based on my experiences in Barbara County in conjunction with research and review of seven Southern/Central California municipal lists and three reference books. These municipalities include the San Luis Obispo, Maria, County of Ventura, Monica, San Diego, and the City and County of Barbara. The revised list includes the original Goleta list, s that should be omitted or added, and reclassification of their placement on the list. Placement is relative to estimated maximum size, which is variable in different regions. The headings below correspond with the attached list and illustrate the criteria that I reviewed (headings are condensed due to width of page). Trees that were recommended for omission from the revised list were based on lack of supply or proven success in our region as st s. Red = remove from list Yellow = add to list (some of these s were previously discouraged) Minimum Parkway Width Botanical Name Common Name Range of Max Height Crown Shape: Variable Evergreen/ Deciduous/ Semi-deciduous *Drought Tolerant (still needs water and may grow better with irrigation) Native Comments Used In These Cities Proven in Barbara San Luis Maria County of Ventura San Diego County of Barbara Monica Bill Spiewak - Consulting Arborist! 4

15 Goleta Tree List & Planting Guidelines: Revisions! Apr 30, 2014 CONCLUSIONS 1. I have determined that eleven (11) s on the current Goleta Tree List should be omitted. These are highlighted in red on the spreadsheet. 2. I have added thirty-one (31) s to the list that include some that were previously discouraged. These are highlighted in yellow. 3. There are a total of sixty-six (66) s recommended on the revised list. 4. Some s have been reclassified in different planter spaces due to estimated maximum size. 5. Prior to selection, also consider the crown shape, foliar habit (evergreen or deciduous), drought tolerance, and native species. 6. Prior to any selection, the site should be re-assessed to be sure the is the right choice for that planting location. An optional cultivar with disease resistance, or fruitless or gender variety could make a better choice for that site. 7. Root barriers should be installed between the planting site and the city right of way. 8. An irrigation regime should be determined prior to planting. 9. Prior to selection and planting, s should be inspected for good health and structure as many young s are infected, structurally defective beyond repair, or root bound. If necessary, structurally prune the and carefully remove any circling roots. 10.The list and planting recommendations should be periodically reviewed and revised as per the Goleta Urban Management Forestry Plan. Different s are frequently introduced to the region and new methods and standards are being developed. In addition, s on the list may become susceptible to significant pests and diseases that may invade our region. Prepared by:!bill Spiewak!! Bill Spiewak!! Registered Consulting Arborist #381!!
