This Chapter is enacted to establish a regulatory framework to address serious adverse effects caused in certain areas of the City by motor vehicle congestion, particularly the parking of motor vehicles on the streets where on- and off-site parking is inadequate to meet the demand for parking. As set forth in more specific detail in Section 9.80.020 of this Chapter, parking by nonresidents of such areas threatens the health, safety, and welfare of all the residents of the City. In order to protect and promote the integrity of these areas, parking regulations are needed to restrict unlimited parking therein by nonresidents, while also providing the opportunity for residents to park near their homes. For the reasons set forth in this Chapter, a system of preferential resident parking is enacted.
