Title:

Indian Carry Stream Crossing Project

This study investigates different design solutions for the Indian Carry Stream Crossing in Moultonborough, NH. The team will create three design solutions, compile a report involving the findings, and provide the landowner’s association with a recommendation. The current crossing consists of twin 42” corrugated metal culverts. Installed 10 years ago by the Indian Carry Landowner’s Association, the culverts are showing serious signs of fatigue and are in need of replacement. The team conducted research on the NH DES Wetlands permitting requirements for culvert replacements and created the designs to fit within these requirements. A hydrology study was also conducted of the site to model expected flow at the project location. This information was used to check the hydraulic adequacy of each design. An area of concern for this project was pipe degradation and various materials were investigated. After compiling the various contributing factors three designs were created to fit the landowner’s variety of needs which includes accessibility, timeliness, and cost effectiveness. The report concludes all findings as well as a recommendation to which design the team believes would best fit the needs of the landowner’s.
