LAKE TRANQUILITY DAM & BRIDGE

CLIENT: Township of Green
DATES OF SERVICES: February 1999

DESCRIPTION: The Lake Tranquility Dam is a Class I dam and is located on Trout Brook a FW2-NTC1 stream located in the Highlands Planning Area. Design included replacement of existing single-lane bridge with a two-lane, weathered steel, arch truss bridge. Included partial demolition and reconstruction of existing abutments, replacement of emergency drawdown sluce gate which required a steel sheet pile cofferdam with bypass control and pumping, vertical and horizontal realignment of roadway, and design of wing walls, scour protection concrete and steel sheet piling cut off walls, and roadway stabilization.

OLD MORRIS CANAL DAM

CLIENT: Town of Boonton
DATES OF SERVICES: 2007 -2008

DESCRIPTION: The Old Morris Canal Dam consists of a granite block spillway across the Rockaway River that is flanked by concrete and stone training walls.  The project consisted of a hydrologic and hydraulic analysis of the dam’s drainage basin and an assessment of the existing dam structure.  SCE then designed grouted riprap overtopping protection for the shoreline above the spillway training walls to provide erosion protection for the 100 year storm event. Additionally, repairs to the stone and concrete training walls and riprap slope protection for the downstream channel were designed by SCE.

TAYLORTOWN RESERVOIR DAM

CLIENT: Town of Boonton
DATES OF SERVICES: 2001 - 2002

DESCRIPTION: SCE provided engineering services for operation, maintenance, regular inspection, hydraulic analysis and reporting as required by New Jersey Department of Environmental Protection (NJDEP) for the earthen dam and associated appurtenances. Design and construction administration service for dam repairs including concrete spillway replacement, riprap embankment protection, rubble stone abutment and wingwall repair, spillway asphalt access road, etc. In addition, a 24-inch diameter siphon was designed to lower the reservoir level in the event of an emergency. All required permits were obtained including NJDEP Dam Safety Permit, Freshwater Wetland Permit, Stream Encroachment Permit and Soil Erosion Certificate.

















SCHOOLEY'S MOUNTAIN ROAD

CLIENT: Morris County Engineering Department
DATES OF SERVICES: 2006 - 2009

DESCRIPTION: SCE designed the intersection improvement plans and prepared the construction documents for the widening and traffic signal upgrades.  The project was initiated due to development in the area which has significantly changed the local traffic patterns.  SCE coordinated the design submission and final approval of the project with NJDOT.  Additional improvements associated with the intersection included analysis and design of drainage infrastructure, roadway guiderail, grading and wall design.  Coordination for the relocation of utilities was a significant obstacle during the preconstruction phase of this project.  The project was constructed in 2009.
