Specifications include, but are not limited to: General • All new/replacement components to be ADA accessible. • All new structures shall comply with seismic design requirements. • Due to periodic flooding, the lower portion of the walls and columns shall be CMU. Above this the use of wood and/or steel construction can be used. Boardwalk • Renovate the existing boardwalk near Visitors Center o For the 900’ long section (most of the loop portion) replace the existing above-water components (horizontal supports, decking, guardrails) with new. See Boardwalk Area Site Plan. o Include code compliant decking and guardrails (guardrails to include wire mesh infill, with 4” square openings). o Renovate/replace any existing pilings as needed • At remaining portion of boardwalk loop (approx. 370’), augment the existing wood guardrails on each side with a wire mesh infill, with 4” square openings to meet code requirements. • Replace 2-Viewing Stations, as well as the roof structure covering south station, along the eastern portion of boardwalk facing the lake (approx. 18’ x 18’). Also include a new roof structure at the north station similar to the south. Include code compliant decking and guardrails (guardrails to include wire mesh infill, with 4” square openings). Blue Bank Area • The Blue Bank area formerly included 2-pavilions, one of which was relatively undamaged (Round House), and another that was completely destroyed (Square House). We recommend constructing a new Square House Pavilion, in approximately the same location as the former version: o Shelter - 60’ x 25’ o Storage room (approx. 120 SF) • Toilet Rooms – 26’ x 38’, to include 4 plumbing fixtures for each gender, and a separate Family toilet room. • Restore electrical power to the Round House. o Remove and replace existing underground power lines from main power source to Square House, and from Square House to Round House. • Demolish the existing lift station and construct a new one, to be closer to the new Square House o Abandon existing gravity sewer line from the former Square House to the existing lift station. o Place a combination check valve approximately 5-8’ from the new lift station, on the discharge side. o Electrical power for the lift station to be routed from Square House. • For the Square House plumbing systems, install a 1.5” copper domestic water service from a backflow preventer and meter on site. Install a 4” PVC sanitary service connection to the local sewer. Install on-demand electric water heaters at each lavatory. Install PEX water piping for all branches. • For the Square-House HVAC, install ceiling mounted exhaust fans in each restroom, controlled by an occupancy sensor. Install a 1-ton ductless split heat pump for each restroom, with condensing units mounted on a wall bracket, above floodplain. • For the Square House electrical systems, install a new 200-amp single phase 120/240 volt electrical service, underground form a pole mounted transformer at the street to a meter base on the exterior of the building. Install a new service panel in the storage room. This service will supply power to the water heaters, the HVAC, the lighting/receptacles, the new lift station, and sub-feeder to the Round House Pavilion. • Provide exterior-grade lighting and WP receptacles in the Pavilion. All lighting will be controlled by timers/switches in the storage room. • Install a 100-amp feeder (fed from the Square House panel) to serve the existing panel in the Round House. • Install three new parking lot light poles on the southeast side of the east parking lot, and three on the street side of the west parking lot, and control them through a timer with photocell. • Refer to Blue Bank Area Site Plan Long Park Area • Reconstruct the existing pier, reusing the existing pilings where possible. An assessment of the pilings will be necessary prior to reconstruction. o Include code compliant guardrails (wood railings with wire mesh infill). o 10’ wide x 200’ long. • Refer to Long Pier Area Site Plan • The Eagle Basin area formerly included a pavilion, and a Concession Stand, both of which were completely destroyed. We recommend constructing a new Eagle Basin Pavilion, in approximately the same location as the former version: o Shelter - 60’ x 25’ o Storage room (approx. 120 SF) • Construct a new Restroom Building, east of the new Pavilion building. o 26’ x 48’, to include 6 plumbing fixtures for each gender, and a Family toilet room. • Construct ADA accessible paved paths from the parking area to both the new Eagle Basin Pavilion and the Restroom Building. • Demolish the existing lift station and construct a new one, to be closer to the new Restroom Building, and provide electrical power from it. o Place a combination check valve approximately 5-8’ from the new lift station, on the discharge side. • Reconstruct the existing pier, reusing the existing pilings where possible. An assessment of the pilings will be necessary prior to reconstruction. The State has repaired about ½ of the pier, so this scope should include the reconstruction of only the other half. o Include code compliant guardrails (wood railings with wire mesh infill). o 10’ wide x 200’ long. • Install new Challenge Course equipment to replace that which was destroyed. • Replace current playground equipment with accessible and inclusive playground equipment - refer to Exhibit F for examples; some of these are entire play structures, while others are individual pieces. Construct an ADA accessible path from the ADA designated parking stalls to the playground. Remove the existing mulch and replace with a pour-in-place rubber surfacing that is ADA compliant. • For the Restroom Building plumbing systems, install a 2” copper domestic water service from a backflow preventer and meter on site. Install a 4” PVC sanitary service connection to the local sewer. Install on-demand electric water heaters at each lavatory. Install PEX water piping for all branches. • For the Restroom Building HVAC, install ceiling mounted exhaust fans in each restroom, controlled by an occupancy sensor. Install a 1-ton ductless split heat pump for each restroom, with condensing units mounted on a wall bracket, above floodplain. • For the new Pavilion building, install a new 200-amp single phase 120/240 volt electrical service, underground form a pole mounted transformer at the street to a meter base on the exterior of the building. Reuse the existing underground conduit pathway if possible. Install a new service panel in the storage room. This service will supply electrical power to the Pavilion, the new lift station, and the Restroom Building. • Provide exterior-grade lighting and WP receptacles in the Pavilion. All lighting will be controlled by timers/switches in the storage room. • In the Restroom Building, install a 100-amp sub-panel (fed from the Pavilion) to serve the water heaters, HVAC, and lighting. Lighting in the Restrooms will be controlled by occupancy sensors. Exterior lighting will be controlled by timers in the storage closet • Install six new parking lot light poles on the street-side of the parking lot and control them through a timer with photocell. • Refer to Eagle Basin Area Site Plan Structural Design • For all structures, the foundations shall consist of concrete spread footings, the design of which should be confirmed after a Geotechnical Report has been prepared. • All new structures shall comply with seismic design requirements. • The floors shall be concrete slab-on-grade, 4” thick, 4,000 PSI. • Due to periodic flooding, the lower portion of the walls and columns (4’ above FFE) shall be 8” CMU. Above this use wood stud framed walls (2x6 exterior, 2x4 interior), and/or steel or pressure-treated wood columns and framing. • For the roofs use either 2x roof rafters or pre-engineered wood trusses @ 24” oc spacing, with plywood sheathing o At areas with exposed roof structure or vaulted ceilings use 2” T&G decking instead of the sheathing • All wood framing components exposed to the elements shall be pressure treated lumber.
