FROM: PUBLIC WORKS DEPARTMENT/ENGINEERING DIVISION
SUBJECT: FREEWAY SOUNDWALL STATUS REPORT
RECOMMENDATION:
Receive and file.
BACKGROUND:
At their January 15, 1990 meeting, the City Council requested a status
report on freeway soundwalls as they relate to developments within the
City of Tustin.
Two freeways, the Santa Ana I-5 and the Costa Mesa SSR -55 traverse
through the City of Tustin. The I-5 freeway enters the southeasterly
part of the City at Jamboree Road and extends northwesterly Main Street,
r�-re or less. The SR -55 freeway enters, or is adjacent to, the City at
ner Avenue and extends northeasterly and northerly to Fairhaven
�.enue.
The Santa Ana I-5 widening project will include the construction of
soundwalls adjacent to all residential properties along the construction
project within the Tustin city limits.
The Costa Mesa SR -55 widening project between Dyer Avenue and Irvine
Boulevard is included within the I-5/SR-55 interchange modification
project. All residential properties adjacent to this project will have
soundwalls constructed as a part of the project.
Soundwalls will not be constructed adjacent to commercial and/or
industrial properties as a general rule.
DISCUSSION:
The residential properties located adjacent to and easterly of the Costa
Mesa SR -55 freeway northerly of Irvine Boulevard are all within the
Tustin city limits. This segment of freeway has no planned construction
of soundwalls. it is anticipated that any future widening of this
segment of the freeway would include the construction of soundwalls.
The following is a recap of what currently exists with respect to walls
and/or fences:
* Between Irvine Boulevard and Seventeenth Street.
The freeway is below grade within this area and
the residences are buffered by either 6 foot
blockwalls and/or wood fences.
