Mark Hanna is a Senior Principal Water Resources Engineer based in Southern California with more than 25 years of experience focused on water and natural resources.
Mark’s experience in civil engineering, water resources, hydrology and hydraulics, and environmental restoration planning and implementation allows him to offer public, private, and non-profit clients comprehensive solutions to the growing problems of water resources, risk, and resiliency in the natural and built environment.
As a consultant, Mark specializes in local water supply reliability, large system hydrology and hydraulics, and surface water and groundwater management, and systems resilience. He also has extensive experience in flood risk management, water rights, watershed planning, hydrologic and hydraulic modeling, permitting, project funding, and multi-beneficial project development. In particular, his practice focuses on three critical water resource areas across the Southwestern United States: local and imported water resource development; systematic restoration, revitalization, and resiliency planning related to urban and coastal waterways; and infrastructure project development and implementation.
Restoration and revitalizing urban and natural landscapes is Mark’s passion. He is focused on resiliency and sustainability related to water resources, ecological systems, and infrastructure, and how these impact health, equity, and displacement. Mark directs multi-benefit integrated water resource projects across many client sectors. He directs the engineering design and development of Lauren Bon and the Metabolic Studio's "Bending the River Back into the City" project capturing and treating over 100 acre-feet per year of urban runoff for beneficial use. Mark manages and directs the County of Los Angeles' update of their 51-mile Los Angeles River Master Plan, and often leads Frank Gehry's water resources team along the Los Angeles River. He consults on the renewal and redevelopment of multiple large parcels along the Los Angeles River from Canoga Park to Long Beach, including the Canoga Park Area, the Aliso Creek/LA River Confluence, LADWP’s Headworks Park, the soft-bottomed reach through the Glendale Narrows, the Los Angeles State Historic Park, Metabolic Studio, Piggyback Yard, , , the LA River Bikeway, the LA River/Rio Hondo Confluence, and retired rail yards along the main river corridor. Mark recently developed a "stormwater as a water supply" feasibility study for the Water Replenishment District of Southern California, leveraging water quality requirements with water supply needs resulting in the design, funding, implementation, and successful operation of the award-winning Broadway Neighborhood Greenway Project. Mark also managed the Los Angeles Department of Water and Power's award-winning Stormwater Capture Master Plan that defined the potential for stormwater to offset future water demands within the City of Los Angeles.
