Monthly Invoices and Progress Reports. Task 11. Gilroy Traffic Analysis The purpose of this task is to support the design of the at-grade crossing improvements at East 10th Street and East Luchessa Avenue in Gilroy. East 10th Street Grade Crossing Traffic Analysis HDR will obtain and review the input assumptions (traffic counts, geometrics, forecasts, software, signal timing) used to support the traffic impact analysis for the proposed grade crossing improvements at East 10th Street. The “Tenth Street-Chestnut Street Commercial Development Transportation Analysis Report,” provided by the City of Gilroy, will be used to determine the 2019 traffic volumes for the intersection of East 10th Street and Monterey Road. HDR will format the data for use in the intersection analysis to support intersection operation and queue analysis. The 2019 traffic volumes from will be grown to 2021 and 2024 which are considered existing year and opening year of the new railroad grade crossing tracks. The yearly growth factor will be developed by reviewing historical traffic count data and other future planning documents for the City of Gilroy. The task will produce the following: • Develop traffic and growth rates to represent existing and future travel conditions: o Existing (2021), o Future Project (2024). • Develop turning movements at East 10th Street and Monterey Road to be evaluated for the following conditions: o Existing 2021 Weekday AM and PM peak hours, o Future Project 2024 Weekday AM and PM peak hours. Based on the scenarios above, intersection operation analysis for the East 10th Street/Monterey Road intersection will be conducted using Synchro 10 software which implements the Highway Capacity Manual’s methods. The analysis will provide advice for queue lengths for key movements to evaluate if there is potential for the proposed rail crossing to be blocked. HDR will prepare a memo summarizing the intersection traffic analysis results for submittal to the City of Gilroy. It is assumed that one round of comments will be addressed, and a final traffic analysis memo will be submitted. HDR will also develop average annual daily traffic (AADT) on East 10th Street and East Luchessa Avenue for following conditions: o Existing 2021, o Future Project 2024. The AADT values will be used to support the CPUC GO 88-B permit applications for the two at-grade crossing modifications. East 10th Street and Alexander Street Traffic Analysis Per request from the CPUC On-Site Diagnostic team, HDR will perform an additional traffic analysis of the 10th Street and Alexander Street intersection to determine whether signal timing modifications are recommended for the intersection. The “Tenth Street-Chestnut Street Commercial Development Transportation Analysis Report,” provided by the City of Gilroy, will be used to determine the 2019 traffic volumes for the intersection. HDR will format the data for use in the intersection analysis to support intersection operation and queue analysis.

The analysis will provide advice for queue lengths for key movements to evaluate if there is potential for the proposed rail crossing to be blocked or if a pre-signal is warranted on either approach. HDR will summarize the traffic analysis results in a Revised Traffic Analysis Memo for submittal to the City of Gilroy. It is assumed that one round of comments will be addressed, and a final traffic analysis memo will be submitted. • Intersection analysis is not required for the East Luchessa at-grade crossing because there is sufficient distance between the nearest intersection and the new at-grade crossing. • Traffic and pedestrian counts are not included in this scope.
