Elk River River's Edge Expansion 2016 — HKGi Aug242015 Additional task: Dock and related access design Task 1-Background Review Review River water elevation records and flood events to establish average and historical high and low water levels as a basis for dock and gangway design. Review with other communities on river that have docks and there experience with products/design, maintenance, storage approaches. Likely candidate cities include Monticello and Anoka. Review with MNCOR the parameters of custom dock and gangway options available. Update survey base map for elevations and grading at shoreline and field verify specific rock and tree situations in the area of the future dock. Task 2—Access and Dock Feasibility Study Based on discussions with area cities regarding best practices for their docking systems,the HKGi team will create a preliminary layout for stair/step access and gangway/dock(ADA ramp not in scope), including the following: • Concrete step with hand rails—material and foundation to be verified • Concrete landing with small overlook with seating area above average high water line • Explore concrete or stone steps to dock ramp/gangway • Dock ramp/gangway with railings hinged for adjustment to water levels • Dock with railing suitable for fishing, and boat access area without railing for boat tie up • Explore integration of kayak docking options • Landscape/shoreline restoration plan as required • Consider how access fits in with future park improvements—future trail/ADA ramp • Structural and Civil schematic approach (not detailed engineering) of planned improvements to accommodate high water events—pilings, slab on grade, anchoring system, etc. • Update the project construction estimate based on the schematic design approach for the stair/gangway/dock Task 3-Develop Maintenance Plan Assist City in developing plan for removal and storage. Including time of year, additional resources needed, location for storage, and routine maintenance.
