High Speed Rail

The High Speed Rail (HSR) route through San Martin has been under discussion for many years starting with a few possible routes and now leading to the selection of a potential preferred alternative.

The preferred alternative alignment is scheduled to be identified in December 2019.  It will be documented in the Draft EIR/EIS to be published in December 2019 for public review and comment. The route will most likely run close to the Union Pacific Railroad (UPRR) through most of San Martin and will result in some changes to the local road system.

In particular, in the center of San Martin and where San Martin Avenue, Middle Avenue, Church Avenue and Masten Avenue would cross the HSR/UPRR alignments. In addition, in order to maintain speeds of up to 185 miles per hour through San Martin, depending upon the alternative selected, the Monterey Road/UPRR corridor could need to be realigned to the west of their present alignments. This could affect property on the west side of Monterey Road from either north of Roosevelt Avenue or north of Chester Avenue all the way north of California Avenue and Llagas Creek up towards Middle Avenue. The impacts would vary depending upon whether the HSR is elevated on a viaduct, or on an embankment, or a blended system at grade along the potential alignments through San Martin.

Maps of proposed alternative routes can be found on the HSR web site at


Then go to Community Meetings then Community Open House Meetings – April/May 2017

The Santa Clara County Department of Planning and Development provided a report on the potential impacts of the viaduct and embankment alternatives.      This can be found at https://www.sccgov.org/sites/dpd/PlansOrdinances/Studies/Pages/HSR.aspx

The staff report was presented to HLUET Committee in May2017      This Constraints Analysis – High Speed Rail AlternativesSummary is available at  http://www.sanmartinneighbor.org/constraints_analysis/              The tables showing potential impact are shown on pages 3, 4, 5, and 6.

The viaduct and embankment alternatives were presented and discussed at the SMNA Annual Meeting on July 22, 2017.  In addition the Blended at Grade alternative was presented and discussed at the SMNA Quarterly Meeting on October 18, 2018, and the presentation to SMNA is shown at http://www.sanmartinneighbor.org/wp-content/uploads/2018/12/San-Martin-Neighborhood-Alliance_DRAFT_181018_FINAL.pdf
