This document is a set of engineering design drawings for the Hogback Pond Dike Repair project at the Minnesota Valley National Wildlife Refuge, located in Hennepin County, Minnesota. The project involves repairing and rehabilitating an existing dike structure with multiple bid items and construction elements. Key details include Base Bid Items A and B for embankment rehabilitation, and two Bid Additive Items (#1 and #2) involving water control structure modifications, pipe replacements, and gravel/topsoil additions. The site plan shows the dike's location near Long Meadow Lake, with detailed typical sections illustrating proposed repairs, slope erosion mitigation, clay liner placement, and specific construction requirements. The project's drawing set includes site plans, water control structure plans, and typical cross-sections, with a quantities chart indicating approximately 1,100 cubic yards of clay fill and 1,333 cubic yards of topsoil needed for the rehabilitation work.
