Johnny Morris is a 387-unit workforce housing development in Austin designed to provide housing for essential community members, including teachers, nurses, and first responders. The large-scale multifamily project includes approximately 15 buildings, multiple resident amenities, and extensive green space. A key challenge was the floodplain that runs through the site, requiring detailed hydrologic and hydraulic analysis, specialized crossing designs, and careful coordination to prevent flooding impacts to neighboring properties while addressing environmental constraints such as erosion hazard zones. Mahoney Engineering provided comprehensive civil engineering services, including floodplain studies, bridge and fire access crossing design, site grading, and coordination of off-site water and wastewater utility extensions. Through innovative engineering solutions and strategic planning, the project secured the necessary approvals, minimized environmental impacts, avoided adverse floodplain effects on adjacent properties, and achieved significant cost savings through an early parkland dedication strategy.
