The City of Cathedral City is part of a Coachella Valley valley-wide partnership involving eight other cities and the County of Riverside within the South Coast AQMD impacted by PM10 control measures identified in the Coachella Valley State Implementation Plan. Cathedral City adopted an ordinance, control measures and operating practices that require street sweeping as a mobile source Particulate Matter micron size 10 (PM10) reduction control measure. Regional arterial street sweeping operations specifically targeting PM10 began in 1997 and have continued through the Coachella Valley Association of Governments (CVAG). The City has provided a portion of its annual AB 2766 funds for CVAG to provide regional arterial sweeping operations. The City has provided a secondary arterial and collector citywide street sweeping program to supplement the PM10 reduction control measures provided through CVAG.

Cathedral City hired a street sweeping contractor through a competitive bid process in May 2004 to use approved alternate fuel vehicles to sweep the Citys streets one time per month. The program has continued annually since then. Combined funding expenditures included labor costs associated with street sweeper operator and maintenance staff, alternative fuel costs and non-administrative direct costs, including, but not limited to, vehicle insurance, normal vehicle maintenance, parts such as brooms, hoses and normal wear and tear vehicle parts in addition to labor. A public hearing was held August 13, 2008, and Street Sweeping information was been publicly posted on the City's website. The current project was completed August 31, 2010.
