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. d: � � L, C 5; �' " '/ , , "/" � 2.
