APPROVAL OF PLANS AND SPECIFICATIONS AND AUTHORIZATION TO
ADVERTISE FOR BIDS- EAST TUSTIN LANDSCAPE REPLACEMENT PROJECT
iSUMMARY: This Landscape Replacement Project will provide for removal and replacement of
approximately 10-,000 diseased plants and upgrade the irrigation system throughout the East Tustin Area
RECOMMENDATION:
It is recommended that the City Council at their meeting of February 17, 1998, adopt Resolution No. 98-
15, approving the plans and specifications and authorizing advertisement for bids for the project subject
to approval of the FY 1997-98 mid-year budget.
FISCAL IMPACT:
The estimated cost for this project is $260,000. Funds for this project will be appropriated as part of
the FY 1997-98 mid-year budget review. (FY 1997-98 mid-year budget adjustments will be considered
under the regular business section of this meeting.)
DISCUSSION:
With the development of the Tustin Ranch area, an extensive system of landscaping was installed to
provide an aesthetically' pleasing environment along with a visual and auditory screening for the
residents from individuals utilizing the sidewalks, bikeways and roadways. A variety of plants were
utilized throughout the area to achieve the above-mentioned result. One of the plants utilized
extensively throughout this area was the Nerium oleander, a large evergreen shrub reaching a height of
12 feet. Staff estimates there were approximately 8,700 Nerium oleander plants planted throughout the
Tustin Ranch landscaping area. During the last three years the Oleander plants have been infected with
a disease, (Oleander Leaf Scorch) that attacks the plants and kills them ~-ithin two years, by slowly
reducing the plant's ability to transmit water through the stems. This disease is transmitted from 151ant
to plant by an insect (Glassy-Winged Sharpshooter) and has infected plants throughout the State.
Recently Escallonia shrubs have 'been also dying. An analysis by a plant laboratoo? has indicated a
pathogen that may be suceptible to commercial treatment is affecting this plant. Staff is currently
treating a test area to detenmne the effectiveness of this chemical fung/cide and whether the wholesale
application will save the remaining plants
Previous projects have replaced 2,200 Oleanders at intersections and entryways into Tustin Ranch. The
proposed project will replace 6,500 diseased Oleanders and 1,500 dead Escallonias. If the chemical
treatment of the Escallonia is not effective, the remaining 1,700 Escallonia plants will also be replaced.
Additionally, as part of the overall district planting scheme an additional 1000 plants would be removed
or relocated to achieve a variety of plants with various colors and textures.

Staff has worked with Robert Goto, Landscape Architect, on the approphate variety and sizes of plants
that can be utilized to replace the remaining Oleanders, and other plants. Mr. Goto is very familiar with
the landscape design in the Tustin Ranch area, having prepared the landscaping plans for numerous
developments in Tustin Ranch. The design' of this project required the architect to actually field verify
the condition and quantity of the plant material, provide construction drawings for the new landscaping,
and incorporate this information into bid documents.
Staff has also identified a number of improvements to the existing irrigation systems which will enable
the system to function more effectively and efficiently. These improvements consist of replacing eight
irrigation controllers along with a substantial number of irrigation spray nozzles with heads more
specifically suited to existing turf areas. Additional irrigation is also needed in order to provide proper
irrigation coverage for the newly planted areas.
Staff anticipates requesting award of the construction contract at the regular meeting of April 2, 1998
with construction to begin in May and be completed by July 1998.
