2010 – 2013


In 2012, the City of Elk Grove opened an extended Longleaf Drive and new 160-foot long, 58-foot wide, four-span, cast-in-place, reinforced concrete slab bridge over Elk Grove Creek. Though small, this important project supported economic growth through improved access to local businesses.


Blackburn provided geotechnical recommendations for the project. We evaluated the feasibility of spread footing, driven pile, and cast-in-drilled-hole (CIDH) pile foundation alternatives for bridge support. Due to scour issues and potential difficult pile driving conditions, we provided recommendations for CIDH piles to support the bridge. Blackburn also provided geotechnical support and quality assurance materials testing during construction. We provided services on time and within budget.
