PROFESSIONAL MEMBERSHIPS:
American Society of Civil Engineers, Associate DuPont Chestnut Run Outfall Repair, Wilmington, New Castle County, DE
Member (former Del. Chapter Director) The principal outfall from an in-line stormwater facility was repaired in-place
DAPE Law Enforcement and Ethics Committee, with lining technology. Subsequently, the outfall began leaking in the vicinity
Member (2004 to present) of a former corroded joint within the original outfall cribbing. It was estimated
that the leak was under 14 feet of head pressure and subsidence from soil loss
(piping) had been recently observed. Landmark reviewed the alternatives and
recommended a pressure-injected expanding foam solution to the problem. Landmark, in conjunction with the contractor,
developed a protocol for injecting the expanding foam to arrest the leak and not require the pond to be removed from service
and did not require extensive excavation or exhumation of the existing infrastructure. Accordingly, the leak was arrested and
pond performance and functionality was again in conformance with local and state regulations.
DuPont Chestnut Run Outfall Erosion, Wilmington, New Castle County, DE
During a heavy rainfall event, the principal stormwater pond for the facility experienced an overflow discharge to its emergency
spillway system. Accordingly, due to the timing of the overflow event, very little tailwater was encountered in the overflow
structure tie-in. The resulting discharge and combined elevation change created velocities that resulted in a total loss of the
rock armor at the inlet which was composed of R-4 rip-rap or equivalent. Based on an assessment of the hydraulics during a
forensic evaluation after the event, it was recommended that Gabions and Reno Mattresses would provide the necessary
stability to withstand a similar event, if it were to occur again. Design Plans were developed and the repair was constructed.
Avenue North Mixed-Use Redevelopment, New Castle County, DE
Principal/Project Manager, responsible for planning, surveying, traffic studies, site/civil engineering, environmental sciences,
and permitting for the redevelopment of the former AstraZeneca site as a 1,864,000 square foot mixed-use development. The
three biggest engineering issues to be solved were how to create an easy, walkable site for the main Avenue where you have
over 12-feet of grade differential; maintaining vehicular and pedestrian access and parking for the three office buildings
currently occupied; and maintaining utility service to the tenants during future phases of construction. Created phasing plans
that allows for new utilities, new roadways and new parking areas to be constructed while maintaining uses by the existing
tenants.
Avenue North Drainage Channel Restoration, New Castle County, DE
Principal/Project Manager, responsible for the planning, floodplain analysis, design, wetland delineation, and environmental
permitting of an award-winning bank stabilization and channel restoration project. New Castle County requested the owner to
assess and correct severe ongoing erosion that lead to loss of tree canopy within an existing drainage channel that was part of
the 72-acre Avenue North 1.864 million square foot redevelopment. Elements of the solution included a small section of
concrete culvert to convey site outflow with an innovative overflow relief design, a two-tiered gabion basket scour hole and
weir structure to control inflow energy, and two J-hook rock vanes in the channel bed to direct water flow. Bank restoration
design reduced the steep slopes of the existing channel and provided protection with selective reuse of site rock, geotextile
fabric, live willow stakes, native plant landscaping and seeding for long-term stabilization.
