AGENDA TITLE: Approve Specifications and Authorize Advertisement for Bids for Replacement of
Raywood Ash Trees, Phase II Project
MEETING DATE: August 21, 2013
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Approve specifications and authorize advertisement for bids for
replacement of Raywood ash trees, phase II project.
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 both Lower Sacramento Road and the
adjacent frontage road and have entered wastewater laterals connecting to a deep wastewater main in
Lower Sacramento Road (Exhibit B). Because of the species' invasive nature, Raywood ash is no longer
an approved species for City planting.
This project has been discussed at the following Council meetings: June 2, 2010, November 16, 2010
(Shirtsleeve Meeting), and November 17, 2010. On February 16, 2011, City Council approved the plans
and specifications and authorized advertisement for bids on phase I removal and replacement of 39
Raywood ash trees on Lower Sacramento Road between Elm Street and Tejon Street described below.
Phase I was completed in September 2012. This included planting alternating trees (Shumard red oak
Quercus shumardii and Mondell pine Pinus eldarica) between the existing Raywood ash trees. The new
trees were placed on forty -foot centers, without disturbing the existing trees. Modifications to the existing
irrigation system were made. Portions of hedge were trimmed back or removed to give the new trees a
chance to become established.
Phase II work will initiate the actual removal of the 39 Raywood ash trees in late 2013. After removal of the
trees, their locations would be filled with bush -type fern cloud Podocarpus gracilior. This varies from the
first proposal which was a tree form and will provide a screening affect of Lower Sacramento Road.
Staff recommends Council approve the specifications and authorize advertisement for bids for phase II
removal and replacement of 39 Raywood ash trees on Lower Sacramento Road. Specifications will be on
file in the Public Works Department. The planned bid opening date is September 11, 2013. The estimated
cost of this project is $25,000.
FISCAL IMPACT: Removal will reduce or eliminate future damage to pavement and
underground utilities from the invasive roots of these trees.
FUNDING AVAILABLE: Funding will be identified atpro' ct award.
