Mitchell Avenue Storm Drain

Tustin, CA

Client: City of Tustin

 

During the City’s routine inspection of the existing storm drain system, they found the existing CMP drain had extensive corrosion and portions of the pipe had rusted away. With an imminent potential for the pipe to collapse, block drainage and impact the street and parkway above, the City hired Civil Works to determine the best course of action and then prepare storm drain improvement plans for that option.

The storm drain is located in the parkway of Mitchell Avenue between Red Hill Avenue and Newport Avenue. The street is a local collector with power poles in the parkway and numerous underground utilities within the roadway.

CWE analyzed several alternatives to rehabilitate or replace the storm drain. These alternatives included a new pipe within the roadway, removal and replacement of the existing pipe, or in-place pipe rehabilitation. We prepared a drainage report including an area wide hydrology study. All alternatives were designed to capture a 10-year storm event. Due to the extensive underground utilities and existing power poles, pipe replacement was cost prohibitive and problematic. The preferred alternative involved pipe rehabilitation using a UV cured PVC liner.

CWE prepared final construction documents for the pipe rehabilitation including upgrading existing catch basins and laterals, installation of new catch basins and laterals and stubouts for future storm drain extensions.
