The addition of a new 54-inch-diameter force main sewer increases capacity for conveying wastewater from the Venice Pumping Plant to the Hyperion Treatment Plant.
In 2017, severe wet weather caused the original 48-inch-diameter force main to exceed its capacity, risking a sewage overflow onto city streets and surface waters.
Extending about 1.9 miles, the force main alignment passes under the Grand Canal, beneath the Marina Del Rey Channel and Ballona Creek wetlands, crossing both City and County of Los Angeles right-of-way. The project underwent stringent environmental review prior to approval by the City and County of Los Angeles and the neighboring community.
The City took a bold and proactive approach to ensure compliance with mitigations during the construction phase, by bringing on ESA as their Environmental Resources Manager to oversee implementation of all environmental mitigations.
In this role, we are developing an Environmental Monitoring Plan (EMP) to ensure compliance with the Mitigation Monitoring and Reporting Program (MMRP), coordination with construction contractors and environmental compliance monitors, and direct reporting to the City of Los Angeles.
ESA is also providing environmental awareness training to the construction management team and all construction crew members as well as overseeing technical specialists that include archaeologists, arborists, a biologist, a noise specialist, Native American monitors, and stormwater specialists.
