Floating The Good Life • Nebraska Game and Parks Commission 31 KAYAKING ON MISSOURI RIVER KAYAKING ON THE NIOBRARA RIVER Figure 7: Landing with Step Approach Constructed landings provide a stable surface to place paddlecraft in the water and enter parallel to the flow of the river. Before designing landings, one should understand the river characteristics and the extent of foundation required to withstand scouring of the riverbank along the face of the landing. Steps constructed to serve as the approach should be limited to sites with steep slopes, where an accessible path is not reasonably possible. A step approach may also serve as a secondary LANDING LAUNCH WITH STEP APPROACH ALTERNATIVE option, nearby a ramped pathway elsewhere on the site. While step approaches require the least amount of site disturbance, it will create safety concerns and limitations to some users or watercraft types traveling to the launch. BLOCK RETAINING WALL alternative is shown where scour potential is high and river access is suitable. A step approach to the natural shoreline launch possible where site and river conditions are suitable. STONE RIP-RAP along riverbank protects and stabilizes the landing. LIMESTONE SLABS provide a stable and durable surface material alternative, which can be manually cleared of sediment from high water events. An AGGREGATE STONE BASE on geotextile fabric stabilizes steps and landing, preventing them from settling unevenly. CONCRETE LANDING provides a stable launching surface. CONCRETE FOOTING for block stabilization may be required by design engineer and block manufacturer. 7' Recommended
