This is a U.S. Fish & Wildlife Service Repair project document for the Kirwin National Wildlife Refuge (NWMR) in Kansas, specifically addressing boat ramp improvements at Kirwin and Multiplex boat ramps. The document contains site plans, design details, and technical specifications for concrete boat ramp repairs and construction.

The project includes the design and construction of two concrete boat ramps with specific dimensions and structural requirements. The North Shore Boat Ramps require a 13-foot-0-inch length with a 1-8-inch slope, while the South Shore Boat Ramps feature a 26-foot-0-inch length with matching slope specifications. Both ramps are designed with concrete construction featuring a 6-inch thickness, embedded aggregate, and reinforced dock sections. The technical specifications detail concrete ramp T-groove profiles with stamped finishes to prevent slipping, including medial sections with hatch designs on a 3-foot x 6-foot dock configuration. The project includes both existing boat ramp conditions documentation through photographs and aerial imagery, as well as detailed construction cross-sections showing the ramp design relative to existing grade levels. The specifications ensure structural integrity through reinforced concrete construction with defined slope angles and surface treatment specifications to address safety and durability requirements for high-traffic recreational waterway access points at the refuge.
