Document Description
The City of Rialto desires to upgrade existing drainage infrastructure conditions within Baseline Avenue from Cactus Basin west to Tamarind Avenue. The project consists of installing an approximately 2-mile or 11,000 lineal feet storm drain system within Baseline Road that would capture flows north of Baseline Road. The storm drain line starts at the Tamarind Avenue/Baseline Road intersection and runs along Baseline Road to the outlet at Cactus Basin No. 3. The new storm drain will be developed within a reinforced concrete box that will vary in size between 6’ x 12’, 7’ x 7’, and 3’ x 10’ depending on the location within the new storm drain alignment. The majority of the storm drain footprint (located within Baseline Road) will be constructed as a 84” reinforced concrete pipe, though a portion of the easternmost section of the alignment, which encompasses the section from Baseline Road to Cactus Basin, will vary in size as either a 72”, 84”, 48”, 36”, or 30” RCP. Flows leaving Basin No. 3 continue on to Basin 1 and 2 and Rialto Channel, which ultimately discharges to the Santa Ana River. Outflow from the Cactus Basin System are limited due to the poor downstream channel capacities.
