This project is being funded jointly by the City of Cincinnati and the U.S. Army Corps

of Engineers (USACE), Louisville District. The forty-one acre park is bisected in the north/south direction by the Roebling Bridge and in the east/west direction

by Mehring Way. PRIME provided structural design services for this project, including designs for Phase 1, Option 1 and Option 2 of this project.

Option 1 included the construction of the Walnut Street Fountain and Grand Stairway. The Walnut Street Fountain included an interactive water feature, stainless steel pergola, structural glass paving with a walking surface, and a 10-foot wide granite stair. The interactive water feature and plaza sit atop a building which houses the public restrooms and fountain mechanical space. The building incorporated an elevator that provides an alternative way of travel from Theodore M. Berry Way level to Mehring Way level. Immediately adjacent are water features that follow the rhythm of the stairs.

Overall, the project is a complex reinforced concrete structure. PRIME designed columns, beams, and retaining walls including a plaza level reinforced concrete slab to support HS20 loading. PRIME also designed the foundation system consisting of auger cast piles/pile caps and grade beams to support the fountain, grand stairs, and approximately 17-foot-high donor wall (retaining wall) along the south side of the Walnut Street Grand Stairway.

Option 2 was the Walnut Street Event Lawn Project. It encompassed a large public gathering lawn area, walkway, a stage, the granite seat walls, and event light poles and moon light poles atop of the parking garage. PRIME designed the supporting structures for the light poles, elevated platform for the stage, and the granite seats walls in addition to the retaining walls for the tree pit and the lawn area.
