Riverside County is a large producer of agriculture in California. The eastern Coachella Valley is one of the largest agricultural regions in the nation. Many valley farm laborers and their families reside in low-income mobile homes with dirt roads. Unpaved roads and other causes are a significant source of fine particulate pollution, which can lead to respiratory ailments in children and adults. The South Coast Air Quality Management District (SCAQMD) and Riverside County joined forces for the Mobile Home Paving Project. This involved roughly 1.3 million square feet of new asphalt covering 9 miles of dirt roads for 35 mobile home parks in the east valley. This helped an estimated 3,700 residents with improved air quality and improved ease of access. MSA was proud to be a part of the project and assisted the Riverside County Transportation Department with engineering design, surveying, mapping and construction support.
