Analysis
The City of Grand Prairie owns and operates a Type I landfill in the immediate vicinity of the Trinity River at MacArthur Boulevard. For years, the boundary of the neighboring horse farm has been gradually eroding due to normal river activity. Since 2015, the rate of erosion has accelerated, potentially threatening the solitary access road to the landfill.
The Grand Prairie Landfill - West Fork Trinity River Erosion Protection Improvements will include development of a preliminary engineering report and a 30% schematic design to inform the City of Grand Prairie on the needed erosion protection measures along the south bank of the West Fork Trinity River near the landfill access road to prevent the migration of the river further south. The project will include necessary surveys to determine the current extents of the river migration from previous available topography, environmental permitting analysis to determine the appropriate USACE permits needed, geotechnical analysis, floodplain analysis, and civil and structural engineering analysis up to a 30% plan level. This project is anticipated to take 15 weeks from Council award.
Chapter 252, Section 22 of the Local Government Code allows for the exemption to competitive bidding when the expenditure is for Professional Services such as engineering services. Halff Associates, Inc. engineering firm was selected as the most qualified professional due to their previous work for the City of Grand Prairie along Kirby Creek, Cedar Creek, Prairie Creek, Johnson Creek, Warrior Creek, Cottonwood Creek, and Fish Creek.
