… The city [Palo Alto] broke ground in September on Bay Area’s first horizontal levee, a gently sloped expanse next to the Regional Water Quality Control Plant that officials hope to finish by next spring. Once completed, landscaped levee will incline from the tide toward Embarcadero Road. The area will be filled with marsh plants that will be treated with treated wastewater from the wastewater plant through an underground pipe. The levee will serve as yet another filtering system for the effluent as it goes from the treatment plant to the Bay.
