San Mateo County GRH Program

The San Mateo County GRH program supports the use of alternative forms of commuting other than driving alone by giving commuters peace of mind in knowing they have a timely and inexpensive way to leave work in case of an emergency.

Our program reimburses people who commute to a workplace in San Mateo County or students who commute to a participating college in San Mateo County for the cost of their ride home in the event they have an emergency or other qualifying circumstance (see Program Rules for details and limitations).

Only GRH trips that originate in San Mateo County (map) are eligible for this program. Commuters who work in other counties should check with their employers for similar programs in those counties.

Commuters can use any form of transportation to get home, such as public transit, ride-hailing app (e.g. Uber or Lyft), carshare, or taxi, and be reimbursed a maximum of $60 per trip (excluding gratuities) up to 4 times per calendar year. If the commuter uses public transit for their GRH ride home, will provide an extra $5 e-gift card reward.

To participate in the GRH program, commuters must first register on's STAR platform. STAR users can access their GRH reimbursement options after logging a qualifying trip. Participants are required to certify that they have read the GRH Program Rules and have abided by them fully before they can be reimbursed.

For qualifed GRH trips, participants may choose from one of the following reimbursement options:

  • Tango Card which can be used for Visa eGift cards, Uber credit or an e-gift card from one of more than 70 participating retailers
  • PayPal

Please note that Visa eGift cards and PayPal reimbursements require the commuter to have an existing Visa or PayPal account or create a new account in order to receive the reimbursement.
