The Beaubien Woods Boat Launch Parking Lot Improvements project consisted of assessing the condition of the existing asphalt pavement parking lot and ring road for the boat launch, removal of the existing parking lot pavement, and re-configuration of the parking lot layout and geometry for a proposed reduced parking lot size and more efficient layout. In addition to the parking lot improvements, an existing retaining wall with associated concrete walk was assessed for overturning and a recommended repair report with a preliminary engineers estimate of probable construction cost was prepared for the Forest Preserve District of Cook County (FPDCC). Working with the Forest Preserve District of Cook County (FPDCC), the existing parking lot pavement area was reduced in size by approximately 45% and the reduced pavement area turned into landscape area in the proposed re-configured parking lot. The proposed re-configured parking lot design reduced the pavement area to the projected number of parking stalls and type as requested by the FPDCC, created additional landscape area, and provided improved vehicular and pedestrian circulation.

TERRA performed civil engineering, structural engineering, and surveying services for the project. Civil engineering services included the creation of construction documents that included permit and construction plans and specifications. Drawing review and permits were obtained from the FPDCC and the Cook County Building & Zoning Department. TERRA also prepared a summary of quantities and an engineer’s estimate of probable construction cost as shown within the civil engineering documents.

TERRA’s structural engineering services included a site inspection and review of the existing concrete retaining walls along the boat launch and concrete walk fronting the Little Calumet River. A report was prepared for the Forest Preserve District of Cook County detailing the findings of the structural inspection and a recommendation on the scope of repair work. In addition to the report, TERRA also provided an engineer’s estimate of probable construction cost for the recommended repair work. The engineer’s estimate of probable construction cost was used to determine the budget, scope of work, and project schedule for retaining wall work.

TERRA’s surveying scope included topographic survey of the project area. The surveyed area was approximately 10.19-Acres in size. The topographic survey included survey of the existing asphalt parking lot and striping, asphalt ring road, two concrete boat launches, grass areas, existing trees and large shrubs, and the edge of concrete walk adjacent to the Little Calumet River.
