Yorba Linda 3 Drainage Improvement Projects   Yorba Linda 3 Drainage Improvement Projects

 

The City of Yorba Linda had issues with poor drainage and flooding during rain storms at three locations within the City. Civil Works Engineers prepared the conceptual designs and final plans, specifications and estimates for improvements at each location.

The first location involved removing a parkway culvert that was directing runoff into the gutter and curb lane of Yorba Linda Boulevard, a curb lane of Yorba Linda Boulevard, a significant City arterial highway. The parkway culvert was replaced with a catch basin and 650 feet of new 24 storm drain pipe was installed within the street to connect the catch basin to an existing storm drain box.

The second location involved installation of additional rip-rap and a trash rack for an existing 84 inlet located at the end of an undeveloped canyon near Hidden Hills Road. The existing rip-rap was broken and additional rip-rap was installed to mitigate erosion issues. The trash rack was installed to capture debris before entering the storm drain and help secure the area from the public.

The third location was within the residential area of Avenida Puesta Del Sol. The existing drainage system used street surface flow to direct flow to one catch basin at a sump location. The sump area had experienced flooding during large storm events. After preparing a drainage report for the area, new catch basins and storm drain pipes were installed to capture runoff and redirect the flow away from the sump area.
