Drainage Improvement & Analyses

BKI was selected by Jefferson Parish Department of Public Works for the construction of a gravity collection culvert system on Bellemeade Boulevard and Brookmeade Drive between Briargrove Street and the Weyerauch Canal. 

In order to determine the best solution to the drainage problems in the area, BKI incorporated previous studies and modeling efforts that were provided by Jefferson Parish. BKI provided preliminary and final engineering design, bidding assistance, construction administration, and resident inspection services.  

The project included the design and installation of 2,800 linear feet of subsurface culverts, 14 junction boxes, 10 catch basins, and 6,000 square yards of paving. 

Coordination with all utilities for potential conflicts and required relocations was required, as well as repaving of all streets damaged or removed to allow construction of subsurface drains and utility relocations.

BKI was selected by St. James Parish and the Pontchartrain Levee District to prepare a master drainage plan for the area bounded by Hope Canal, the Mississippi River, Panama Canal/Bayou Conway, and Lake Maurepas. 

The goal of the study was to alleviate flooding in the existing subdivisions and agricultural lands through development of better outfalls. 

The existing drainage flowed overland through the wetlands to Lake Maurepas. The only existing outfalls in the study area were the Parish Canal, Pipeline Canal, Bayou Des Acadiens, and Blind River. 

The study was performed utilizing the HEC-GeoHMS and HEC-GeoRAS modeling software to determine the potential of improving the existing canals or the need for a new outfall. This phase of the study determined existing drainage conditions, created an existing conditions model and identified drainage and flooding problem areas.

BKI was selected by Jefferson Parish, LA to provide engineering services for the drainage improvements in the Maplewood subdivision area, which has historically flooded during intense rainfall events. FEMA Hazard Mitigation Grant Program funds were awarded to Jefferson Parish from Hurricane Gustav.

BKI provided preliminary and final engineering design, bidding assistance, construction administration, and resident inspection services. Work included the design and installation of 9,100 linear feet of subsurface culverts, 33 junction boxes, 80 catch basins, and 3,500 square yards of paving. A major part of BKI’s effort was performing the design and construction within the available grant funds.
