Horner & Shifrin provided engineering design services for a new 97.8-acre park located south of Hwy. 364, between Pitman Hill Road and Kisker Road. The objective was to offer a recreational facility within the “golden triangle” of three major highways: I-70, I-64, and Hwy. 94.
Amenities included an off-leash dog park, two lakes, a large inclusive playground, multi-use walking and biking trails, three rentable shelters, fishing dock, disc golf course, and a maintenance building. Areas were designed for recreational sport team usage for soccer and/or football. Design services included survey, site layout, grading, hydraulics, roadways, trails, water lines, sanitary sewer lines, storm drains, site lighting, electric service, bridges, and building structural design.
Bridge design services included foundation design for three pre-fabricated steel truss bridges, plans for a Contech pre-fabricated concrete bridge and rehabilitation of an old farm road bridge. The bridges had aesthetic elements including fences and ledge rock finishes.
Civil site design included detention analysis of two lakes used for fishing, including forbays designed for water quality benefits. Hydraulic analysis was required for the work within the floodplain. Permitting through St. Louis County and Missouri Department of Natural Resources was required for extensive stormwater management and siltation control. The previous farm silo from the early 1900’s was incorporated into the playground area as an amenity to the park, providing a connection to the heritage of the land.
Project challenges included an existing pipeline that bisected the property, and the grading and construction equipment over the pipeline was highly limited.
H&S worked with the County during construction to provide the final product as the design intended.
The project was so successful that the County contacted H&S to provide concept plans for additional parking options. The County also subsequently added an overlook with a veterans memorial.
