What is the test for making reasonable modifications in policies, practices or procedures to avoid discrimination on the basis of disability?

"Generally, public entities must 'make reasonable modification in policies, practices, or procedures when the modifications are necessary to avoid discrimination on the basis of disability, unless the public entity can demonstrate that making the modifications would fundamentally alter the nature of the service, program, or activity.'" Pierce v. County of Orange, 526 F.3d 1190, 1215 (9th Cir. 2008) (quoting 28 C.F.R. 35.130(b)(7)).

To state a claim under Title II, the plaintiff must allege four elements: (1) the plaintiff is an individual with a disability; (2) the plaintiff is otherwise qualified to participate in or receive the benefit of some public entity's services, programs, or activities; (3) the plaintiff was either excluded from participation in or denied the benefits by the public entity; and (4) such exclusion, denial of benefits or discrimination was by reason of the plaintiff's disability. Simmons v. Navajo County, Ariz., 609 F.3d 1011, 1021 (9th Cir. 2010); McGary v. City of Portland, 386 F.3d 1259, 1265 (9th Cir. 2004); Weinrich, 114 F.3d at 978.
