Kansas City, Missouri
Responsible for alignment study, preliminary engineering and construction engineering for a 2-mile trail segment of the Trolley-Blue River Connector Trail that provides the connecting link between the Indian Creek Greenway Trail, Blue River Trail and Trolley Trail.
The alignment study considered cultural, economic, environmental, right-of-way and flood plain impacts. Project clearances in accordance with National Environmental Policy Act (NEPA) included COE404 permit for bank stabilization along Indian Creek, Section 401 Water Quality Certification from MDNR, Section 106, Section 106 Historic Preservation Clearance from MDNR and Section 4F parkland clearance. The project includes a 330 foot, two-span, 3-section bike/pedestrian bridge over Indian Creek to pass the 100-year flow without impacting the 10-year water surface elevation.
The bridge abutments were set back 25 feet from the top of bank to mitigate 404 impacts. An intermediate bent was installed to provide the required conveyance area and reduce the bridge section lengths. A hydraulic analysis using HEC-1 was comprised and a no-rise certificate issued for the bridge.
