Reasonable Modification Request

A reasonable modification for purposes of complementary ADA Paratransit is a modification to Rancho Research Institute (RRI) Transportation Deparment’s policies and procedures that are requested by an eligible customer to ensure they are able to use the paratransit system.


To request a reasonable modification to current policies and procedures, such as the “Beyond the Curb” service, please call our transportation department at (562) 385-6778.


RRI Transportation Department may deny requests for modification where:

  1. Granting the request would fundamentally alter the nature of RRI Transportation Department’s services, programs, or activities;

  2. Granting the request would create a direct threat to the health or safety of others;

  3. It is determined that the patient is able to fully use the services, programs, or activities for their intended purpose without the request modification;

  4. Granting the request would cause an unreasonable financial or administrative burden.

For more information, please contact the RRI Transportation Department Supervisor at (562) 385-6778 or at
