SUBJECT: I-5 WIDENING PROJECT SOUNDWALLS FRONTING TUSTIN HIGH SCHOOL
RECOMMENDATION:
None. Receive and file.
DISCUSSION:
At the July 2, 1990 City Council meeting, Councilman Potts requested
City staff to contact Caltrans and determine when the soundwall will be
constructed along I-5 fronting Tustin High School.
Because of funding limitations it was not possible to construct full
freeway improvements through Tustin with the I-5 widening project now
under construction. The widening will only be completed from the south
to Red Hill Avenue. Transitional improvements will be constructed from
Red Hill Avenue to Newport Avenue.
Other than the realignment of E1 Camino Real, the freeway work north of
Red Hill Avenue, including the Tustin High School frontage, will be
limited to storm drain construction, embankment, temporary freeway
access ramps and retaining walls. The I-5 widening north of Red Hill
Avenue, including soundwalls, is scheduled to be included in the
construction of Phase III of the I-5/SR-55 interchange reconstruction.
That project is to begin construction in October 1991.
In the interim, the retaining wall to be constructed fronting Tustin
High School on the current project will function as a soundwall for most
freeway traffic noise. Some sound from on-ramp traffic will reflect
over the retaining wall. The present schedule calls for the
reconstruction of the north half of E1 Camino Real fronting Tustin High
school to be completed by September 1990. Construction will then begin
on the freeway retaining wall fronting Tustin High School and will take
approximately six months to complete. As stated before, the retaining
wall should be reasonably effective as a sound barrier until the sound
wall is built with the project to follow in 1991.
