COUNCIL COMMUNICATION FM AGENDA TITLE: Approve Plans and Specifications and Authorize Advertisement for Bids for the Phased Removal and Replacement of 39 Raywood Ash Trees on Lower Sacramento Road between Elm Street and Tejon Street MEETING DATE: February 16, 2011 PREPARED BY: PublicWorks Director RECOMMENDED ACTION: Approve plans and specifications and authorize advertisement for bids for the phased removal and reptacement of 39 Raywood Ash trees on Lower Sacramento Road between Elm Street and Tejon Street. BACKGROUND INFORMATION: Trees are a benefit to the urban environment. As a result, the City removes trees only when they become a significant liability to the infrastructure or compromise public safety. The existing RaywoodAsh trees (ExhibitA), planted in approximately 1988, have extremely invasive root systems. They have caused extensive damage to the surfaces on Lower Sacramento Road, the adjacent frontage road, and are threatening a deep wastewater main in Lower Sacramento Road (see attached photos, Exhibit B). Because of the species' invasive nature, Raywood Ash is no longer an approved species for City planting. June 2, 2010 Council Meeting: City Council directed staff to evaluate alternative methods and to coordinate this effortwith Tree Lodi. Through consultation with Tree Lodi, staff evaluated various alternatives, including the installation of root barriers and root surgery, tree removal, and phased removal of the trees. It was recommended that removal was the only way to permanently deal with the invasive nature of these trees and avoid future damage to City infrastructure. In the attached letter (Exhibit C), Tree Lodi agrees with staffs recommendation and adds, "Raywood Ash trees are too large for the area in which they are located." Tree Lodi suggested a phased removal and planting program. This involved removing and replacing about every other tree at first, followed by removing and replacing the others a year or two later. November 16,2010 Shirtsleeve Meeting: The City Council met in the field to view the damage firsthand and discuss the replacement further. November 17,2010 Regular Council Meeting: Council directed staff to modify the removal plan to further reduce the visual impacts associated with the phased tree removal. Staff again consulted with Tree Lodi, reflected in the attached memorandum (Exhibit D), regarding the planting and removal schedule and tree types and recommends the following revised plan (Exhibit E): APPROVED: 1. k1�� Konradt Bartlam, City Manager KAWP\000NCIL\2011\specsRaywoodAsh Removals. doc 02/02/2011 Approve Plans and Specifications and Authorize Advertisement for Bids for the Phased Removal and Replacement of 39 Raywood Ash Trees on Lower Sacramento Road between Elm Street and Tejon Street February 16,2011 Page 2 Phase 1: Plant alternating trees (Shumard red oak "Quercus shumardii" and Mondell Pine "Pinus eldarica") between the existing Raywood Ash trees, The new trees would be placed on forty -foot centers, which will not disturb the existing trees. Portions of hedge will have to be removed for the new trees, but this will give the new trees a chance to get established. This is proposed to take place as soon as possible, should Council approve the plan. Modificationsto the existing irrigation system will be made. Phase 2: Initiate actual removal of the Raywood Ash trees in December 2012. After removal of the trees, their locations would be filled with bush -type Podocarpus gracilior "Fern Cloud." This varies from the first proposal which was a tree form. This type will provide a screening affect of Lower Sacramento Road. Exhibit E reflects the planting configuration for a typical section of the proposed project. The entire plan will be available at the Public Works Department. Staff recommends Council approve the plans and specifications and authorize advertisement for bids for the phased removal and replacement of 39 Raywood Ash trees on Lower Sacramento Road. Plans and specifications will be completed following Council action and will be on file in the Public Works Department in approximately 14 days. FISCAL IMPACT: Removal will reduce or eliminate future damage to pavement and underground utilities from the invasive roots of these trees, saving thousands of dollars. FUNDING AVAILABLE: Funding for this projectwill be coming from Streets and Drainage (320013) and Wastewater (171013). A requestfor appropriation of funds will be made at contract award. Project Estimate: $30,000 F.

The Raywood Ash trees are too large for the area in which they Stfwards are located. Their large, shallow and vigorous root systems have caused curb, NBce Butcher gutter, asphalt and sewer damage. As these trees enlarge, they will continue to Darrell Drummond cause infrastructure damage. Gerry FSsh RayFe Derric Juano RECOMMENDATIONS: Tree Lodi recommends removing about half the Esther Mimes trees in the first year, perhaps the most damaging ones first, then replant about Nancy Nakamura half. Wait one or two years to establish the new trees, then remove the Robert itaingruber Vern weigum remaining trees and replant. This removal and replanting sequence would minimize 'removal shock' and the loss of screen for the neighborhood. REPLACEMENT TREES: The recommended replacement tree size is 24 - inch box or 15 gallon container. The following types of trees are recommended forthis ansa: 1. Fern Pine, Podocarpus gracilor, an evergreen, 2. Bowhall Maple, Acer rubrum Bowhall', 15 ft wide, deciduous, 3. Parkway Maple, Acer platanoide `Parkway', 25 ft wide, deciduous We at TRE LODI thank you for the opportunity to share t h i s information with r you; f .' i Gordon Schmierer, President Tree Lodi, Inc., a7i5 W.

Tax ID#z8io577 EXHIBIT D Lodi Parks and Recreation Department The Benefits are Endless MEMORANDUM To: Curt Juran, Street and Drainage Superintendent From: Steve Dutra, Park Superintendent Date: February 1,2011 Subject: Tree removal/replacement You had requested some follow-up from Tree Lodi related to your recommendation of Quercus ilex, Holly Oak and Quercus coccinea, Scarlet Oak as Raywood Ash replacements. Tree Lodi members have provided me the following comments related to your recommended specie selections: Holly Oaks tend to have heavy acorn crops; female trees have a heavy catkin load and specie tend to receive molds and diseases. The area in question can accommodate more excurrent specie vs. more decurrent specie such as Holly Oak. Scarlet Oak tend to be slow growing, may experience soil problems related to this specific site and may not perform well overall. Tree Lodi does support your recommendation of removal schedule and numbers removed pre cycle. I.e. some removed this winter, inter planted this spring Tree Lodi again recommends the Podocarpus gracilior, Fern Pine and the Acer rubrum 'bowhall'. Additional the following trees should be considered as replacement species: Acer rubrum'october glory'— most Red Maples will handle said soil types (poorer soil conditions). An example of this tree is located along the west wall of the stadium 12 building. Excellent branch structure, excellent fall color, low root damage rating and easily trained for vehicle traffic lane areas. Quercus shumardii 'shumard red oak'— well behaved tree, excellent fall color, and low to moderate root damage potential. Examples of this specie can be found at Blakely Park. No disease, insect, surface root or abiotic disorders have been seen on either of these recommended species. Both species have been at these listed locations for five to seven years. Additionally, regarding an evergreen tree recommendation Tree Lodi supports two pine species.
