Question: When was the Tidal Force and Canyon River Rapids changed into the new Boardwalk?
About the article "Hersheypark", section "Pioneer Frontier".

Candidate passages:
The largest area of the park, Pioneer Frontier, the southwestern-themed section of the park, includes four of the park’s roller coasters: Trailblazer (the second oldest in the park), Sidewinder, Storm Runner, and Fahrenheit.
It also includes the Frontier Flyers, The Howler, Mini Scrambler, and Livery Stables.
It also has its own food court which features a wide variety of restaurants.
The section previously included the area up to and including Tidal Force until 2007 when Tidal Force and Canyon River Rapids were rezoned into the new Boardwalk.
In 2007, Hersheypark celebrated its 100th anniversary.
A fireworks show occurred every weekend, and as another aspect of the celebrations, Hersheypark opened The Boardwalk at Hersheypark, a water park and themed area.
The area filled in the remaining grass area of Midway America.
East Coast Waterworks, a water play area, Coastline Plunge, four water slides, a FlowRider called Waverider, a kiddie wave pool called Bayside Pier, and Sandcastle Cove, a kiddie water play area were opened.
Roller Soaker and Tidal Force were included in the new themed area, as well as Canyon River Rapids, which would be removed following the 2008 season.
With the opening of the Boardwalk, the Canyon River Rapids and Tidal Force queues had their entrances and exits rerouted.
Following the 2007 season, the Western Chute-Out water slides were removed, as Coastline Plunge had effectively replaced them that season.
In Chute-Out's place, Fahrenheit, Hersheypark's 11th roller coaster, built by Intamin of Switzerland.
When it opened, it held the record for steepest drop at a 97 degree angle (commonly referred as a negative drop).
In March 2008, the Hershey Entertainment Complex was certified as Storm Ready by the National Weather Service.
This is awarded to communities and organizations/companies that are prepared for Severe Weather.
The Hershey Entertainment Complex was certified based on their emergency action procedures, emergency evacuation plans and evacuation shelter(s) capability.
The complex contains an extensive system of CCTV Security Cameras, trained security personal and extensive weather spotting and detecting systems.
In 2009, a new section of the Boardwalk was opened, replacing Canyon River Rapids.
It was nicknamed "the SeaQuel" and featured two major water rides - a wave pool, The Shore, and a lazy river, the Intercoastal Waterway.
The SeaQuel also included the addition of cabanas which was an additional cost for use.
The cabanas entrance forced the removal of Rodeo from the park.
Rodeo was relocated to Dutch Wonderland.
As of 2011, The Boardwalk is home to six games, eleven retail centers and thirteen food concessions. 
Congo River Rapids first opened in 1986 named Grand Canyon Rapids and was part of the Aqua Land area of the park.
The entrance to the queueline was originally located where the path to Katanga Canyon starts in Mutiny Bay today, meaning that the ride was hidden from view.
This was changed when Katanga Canyon was built in the centre of the rapids circuit, as part of John Wardley's plan to open up the area.
Katanga Canyon opened in 1992 along with the new Runaway Mine Train.
The Grand Canyon Rapids were rethemed to adopt the African safari theme of the new area, including the change of name to: "Congo River Rapids".
The original boats held six riders, but were exchanged years later for eight seat boats, to increase passenger throughput. 
A boardwalk existed in the 20th century.
A new boardwalk was built in the 1910s by the Harbour Commission, in the Amusement Park area.
In the 1930s, the boardwalk was re-constructed as a make-work project and extended from the Humber to Jameson Avenue to the east.
This was eventually removed in the 1960s.
In the 1990s, a new boardwalk, constructed of planks of recycled plastic was built along the shore from the foot of Roncesvalles west to the Humber River.
The route of the boardwalk was changed to be closer to the water.
Along the path of the old boardwalk, the Martin Goodman Trail recreational pathway path has been constructed.
These meet at the Humber River mouth where the Humber Bay Arch Bridge bridge was constructed to cross the Humber River to lakeshore parks to the west of the river.
