City Garden
The St. Louis Sculpture Garden, now known as City Garden, was an exceptional project in which to take part. The City Garden is a two block area in downtown St. Louis redeveloped into ADA-accessible outdoor sculpture park with walking paths, fountains, a rain garden, and site retaining walls, complete with a maintenance building and café.
In our role as civil and structural engineer we had the opportunity to work with several world class organizations included the Gateway Foundation: Nelson Byrd Wolz Architects, the Missouri Botanical Garden, and Studio Durham Architects
The intricacy of the site design was challenging and included sustainable design elements such as water infiltration systems within public street right-of-way, intense drainage, and infiltration systems to serve all of the planted areas and green roofs.
Frontenac Engineering provided utility and sewer design and relocations within the short schedule that required excellent working relationships with the utility companies, the sewer district, and St. Louis City building authorities
