While it may not seem like an ideal site for a golf course, Pacheco Koch is never one to shy away from a challenge. After being selected as the civil engineering firm to provide a floodplain fill permit for the Trinity Forest Golf Course and Elam Roadway Improvements, the team worked with Terracon to develop construction plans for the Elam and Simpkins landfill cap repair and remediation project for the City of Dallas.
A detailed hydrologic and hydraulic analysis was conducted for both the main stem of the Trinity River and Tributary 4B5, a minor tributary of the Trinity River. The floodplain fill permit and analysis were expedited and completed within three weeks to meet pre-determined milestones, so the golf course construction could immediately follow the landfill cap repair and remediation project.
The project included hydraulic analysis and design of proposed cart bridges, valley storage calculations, a jurisdictional assessment of environmental features, and a tree survey of the entire site. The project also included coordination with USACE, the City of Dallas, and the developer. A comprehensive drainage report was prepared for the City of Dallas to demonstrate compliance with City floodplain fill criteria. Pacheco Koch worked with the developer and the City to ensure that the sensitive timelines of the two interconnected projects could be met.
