Overview
Horner & Shifrin provided civil, structural, electrical, and site design services for a new 58-acre park west of I-64 and north of Hwy. DD for the City of O’Fallon, Missouri. The City desired to add a recreational facility in the southern portion of the City for use of area residents, as most of the current recreational facilities are located in the middle and northern areas of the City limits.
Park amenities included an activity center with a 325-person event space, outdoor amphitheater, large feature playground with water play area, group camping area, mulit-use trails, group picnic shelters, restroom facilities, a salt storage building, and a maintenance facility. The park is located adjacent to O’Day Creek, which was protected from the construction activities to remain in its pristine condition.
Horner & Shifrin’s design services included site layout, grading, culvert design, drainage, detention, water quality, sanitary sewers, traffic analysis, water distribution, electrical distribution, site lighting, and structural building design.
The stormwater design included seven detention basins, five of which also included water quality Best Management Practices (BMPs). The existing and proposed site hydrology was modeled with PondPack to provide assurance that the proposed condition would not have an increased flow rate over the existing at the downstream point of the property. Additional prairie was added into the open space of the park to attract butterflies and other wildlife.
H&S’s services continued through construction to assist the City in shop drawing review, site visits, punch list, and additional information requests by the contractor.
The success of the new park provides opportunities for walking, hiking, picnicking, camping, and outdoor entertainment or weddings at the amphitheater. The multi-purpose facility is used for meetings, retreats, day camps, and wedding receptions. The park maintains the natural character of the surrounding wooded area, while enhancing the habitat for wildlife.
