Newark Firm’s Innovative Approach Rectifies Erosion, Enhances New Development
Landmark Engineering, of Newark, Del., has earned a National Recognition Award for exemplary engineering achievement in the American Council of Engineering Companies’ (ACEC) 54th annual Engineering Excellence Awards (EEA) for the Avenue North Channel Restoration Project in Wilmington, Del.
As part of the redevelopment of the former AstraZeneca U.S. headquarters into a 1.86-million-sq-ft mixed-use community, Landmark Engineers restored a severely eroded earthen stormwater channel that had caused a substantial loss of tree canopy in a forested area. The project team designed structural and vegetative measures for long-term bank stabilization, combining site rock, geo-textile fabric, live willow stakes, and native landscaping to reinforce the steep slopes.
An innovative, two-tiered gabion basket structure mimics a scour hole and weir to reduce channel velocity and inflow energy, enabling an underground stormwater network to collect drainage from the 60-acre site. Two J-hook rock flow vanes and scour pools constructed in the channel bed direct and slow the stormwater, while a box culvert with customized wingwalls and overflow chute controls outflow from the site. The sustainable and attractive site features will play an important role in preserving the site’s integrity and water quality for decades to come.
The project is eligible for additional honors as part of 173 entries this year representing engineering excellence from throughout the nation and the world. Judging for the awards program—known industry-wide as the “Academy Awards of the engineering industry”– took place in February and was conducted by a national 20-member panel of built-environment leaders, along with experts from government, media, and academia. Award criteria focused on uniqueness and originality, technical innovation, social and economic value, and generating excitement for the engineering profession.
Recognition of all award winners including top winners—20 Honor Awards, 16 Grand Awards, and the prestigious “Grand Conceptor Award” for the year’s most outstanding overall engineering achievement—will take place during the 2021 Virtual EEA Gala, to be held Thursday, June 17, 2021.
