Hurtgen 05E.pdf

This is a Scope of Work document for Dunn County, Wisconsin, detailing specifications for the installation of a snowmobile bridge across Sandy Creek in the Village of Downing. The project involves construction of a bridge structure on private property owned by William and Lori Hurtgen located in the NW1/4, SE1/4, Section 30, T30N R14W. The bridge must accommodate snowmobile traffic and meet all applicable hydraulic, hydrologic, and floodplain requirements. The project is anticipated to span two years, with a hydraulic and hydrologic study and floodplain elevation determinations required to be completed by December 1, 2021, and the bridge installation to be completed by December 1, 2022, contingent upon project approval following the study phase.

The scope specifies that all design and construction must comply with applicable federal, state, and local regulations governing floodplain management, bridge construction, and environmental protection. The contractor shall be responsible for obtaining necessary permits and approvals prior to commencing work. Engineering analysis and hydrologic modeling must demonstrate that the bridge will not adversely impact flood stages or flow patterns in Sandy Creek. The project timeline indicates that the hydraulic and hydrologic assessment phase is critical to determining project feasibility before proceeding to the construction phase.
