the neighborhoods of tustin town center: a new ... - City of Tustin

add additional traffic at the intersections of Newport Avenue at Walnut Avenue and Walnut
Avenue at McFadden Avenue but no capacity issues are expected since the current LOS at these
intersections is “A.” It is likely that with Alternative A and an increase of around 20% daily trips in
the area due to the land use changes as well as closure of Pasadena Avenue to Sycamore Avenue
that the intersection with the highest existing LOS (LOS “C”), Pasadena Avenue at McFadden
Avenue, may experience higher LOS due to additional through traffic along McFadden Avenue.
The addition of residential units and increase in traffic along Newport Avenue due to increased
land use intensity and the closure of Pasadena Avenue may trigger the need for signals at the
current Myrtle Avenue/Newport Avenue intersection. However, Altadena Drive and Myrtle Drive
within the Southern Gateway are internal and narrow neighborhood streets that are expected to
be slow speed and therefore would not be conducive to through traffic.
Neighborhood Plan Alternative B includes a proposal to potentially add a new east-west
street between Pasadena Avenue and Newport Avenue north of Altadena Drive and the
potential vacation of Altadena Drive, Bliss Lane, Pasadena Avenue south of Altadena Drive,
and Myrtle Avenue south of the new street if lot consolidations occur. There are currently no
capacity issues with the highest level of service of LOS “C” in the PM peak hour at Pasadena
Avenue and McFadden Avenue intersection. The same concerns/issues that were discussed in
Neighborhood Plan Alternative A apply for Alternative B. Instead of signals needed at Newport
Avenue and Myrtle Avenue, which is vacated in Alternative B, the signals could be warranted at
the new potential east-west road at Newport Avenue. However, a more direct connection such as
provided by the new east-west road from Pasadena Avenue to Newport Avenue could potentially
attract through traffic in the neighborhood especially by vehicles that are from to/from the SR-
55 northbound ramps at Sycamore Avenue or southern parts of Tustin if the southern portion of
Pasadena Avenue was potentially closed or vacated.
No significant traffic impacts are expected with the proposed location of the youth center in both
Neighborhood Plan Alternatives A and B except for the possibility of a new signal which may be
warranted at the new intersection of Newport Avenue at Myrtle Avenue (Alternative A) or the
new east-west road (Alternative B). In addition, if under either alternative the proposed vacation
of Pasadena Avenue to Sycamore Avenue is pursued by the City, the City will need to work with
Caltrans to provide proper signage in order to inform drivers of the new route to/from the SR-55
northbound ramps.
