Mobility and access to transportation are key quality of life and environmental issues. In western Riverside County, mobility is addressed by making sure that development pays its way, funding transportation improvements for the increased traffic it creates. The effort to establish the Western Riverside County Multi Species Habitat Conservation Plan (MSHCP) included a transportation component that imposed fees on new development to fund transportation infrastructure which, in turn, was mitigated by the adding of nature reserve land under the MSHCP. In addition, Riverside County taxes itself to pay for transportation improvements with a half-cent sales tax. Those revenues fund public transportation including public transit, specialized transit for seniors and the disabled, and commuter rail as well as roadway improvements.
