' COUNCIL COMMUNICATION AGENDA TITLE: Adopt Resolution Authorizing City Managerto Execute Purchase Order with West Coast Arborists, Inc., for the Phased Removal and Replacement of 39 Raywood Ash Trees on Lower Sacramento Road between Elm Street and Tejon Street and Appropriating Funds ($17,275) MEETING DATE: PREPARED BY: November 17,2010 PublicWorks Director RECOMMENDEDACTION: Adopt resolution authorizing City Manager to execute purchase order with West Coast Arborists, Inc., for the phased removal and replacement of 39 Raywood Ash trees on Lower Sacramento Road between Elm Street and Tejon Street and appropriating funds in the amount of $17,275. 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 Raywood Ash trees (Exhibit A), 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). The trees have already necessitated the installation of a new sewer line in the adjacent frontage road at a cost of approximately $100,000; and repairing the current damage to the rubberized pavement on Lower Sacramento Road could be substantial if removal and replacement of the existing asphalt is required. Because of the species' invasive nature, RaywoodAsh is no longer an approved species for City planting. At the June 2, 2010 meeting, City Council directed staff to evaluate alternative methods and to coordinate `this effort with Tree Lodi. Consultation with Tree Lodi yielded various alternatives, including the installation of root barrier, tree removal, and phased removal of the trees. Arborists from West Coast Arborists, Inc. (WCA) and Tree Lodi agreed installing a root barrierwas not a preferred option since it would be a temporary solution and the price exceeded $35,000 (twice the amount of removal and replacement). All did agree that removal was the only way to permanently deal with the invasive nature of these trees. In the attached letter (Exhibit C), Tree Lodi suggested a phased removal and planting program. This involves removing and replacing about every other tree at first, followed by removing and replacing the others a year later. This allows the new trees to become established before removing the remaining trees. This approach is intended to soften the visual impactto those residents living in the area. Staff will also follow Tree Lodi's suggestions for replacement trees that are Podocarpus'gracilior' and Acer rubrum 'bowhall'.

WCA has an existing contract with the City, and tree removal was an optional bid item on the contract. The second phase would be completed by December2011. FISCAL IMPACT: Removal will help mitigate future damage to pavement and underground utilities from the invasive roots of these trees savings thousands of dollars.

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.
