Whitewater Park Construction Party this Saturday

Everyone is invited to a “Construction Party” being hosted by McAlvain Construction, the City of Boise, and Idaho River Sports this Saturday (11/12/11). This is a celebration of Phase 1 construction of the Boise River Recreation Park.

Location: Idaho River Sports
Time: 10 am to 2 pm.

Walter McBrier, the McAlvain Construction project manager, will be there in the morning to give tours and answer questions about project and the construction. Since it is a construction site, anyone taking the tour is required to wear closed toe shoes and a limited number of hardhats and vests will be available for each tour. Come early to make sure you get on a tour of the site! If you haven’t seen it the construction site is truly something, the Boise River has been diverted through Quinn’s Pond leaving the river channel dry and under construction.

You will also have the opportunity to see the “waveshapper model” built by Centennial High School students, which demonstrates how the waveshapper will provide water to irrigators while also providing an adjustable wave for playing on the river in kayaks, surf boards, canoes and inner tubes. Walt, Friends of the River Park, and Boise City Park and Rec Staff will be on hand to discuss this exciting project. Idaho River sports will be providing hot chili and hot apple cider to warm you up after the tour. Call 336-4844 for more information.

Construction of River Recreation Park Begins

 The Planning and Zoning Commission Monday night approved a river system permit for the first phase of the whitewater park, which will include widening the river bank and replacing of the Thurman Mill Diversion. A spokeswoman for Boise Parks and Recreation tells us that crews will begin preparing the site Tuesday. The Greenbelt will be closed as early as Wednesday when construction would begin.

 The permit allows for clearing and excavation of the river bank at the site and for improvements associated with the replacement of the Thurman Mill Diversion and construction of the first phase of the park. The future park site is located near 3400 W. Pleasanton Ave. west of downtown Boise between Main Street and Veteran’s Memorial Park.

During the five-month construction project, the Greenbelt will be closed on the north side of the river from Main Street to the Pleasanton spur and the 36th Street pedestrian bridge. Signs mark a pedestrian detour around the construction zone.  At more than 100 years old, the existing Thurman Mill diversion is in serious disrepair. Over the years, the structure has created a public safety hazard resulting from a dangerous hydraulic situation at most river flows. The project includes replacement of the aging diversion and construction of a new fully automated structure that will allow for in-river recreation activities.

To take advantage of low water in the Boise River, crews are scheduled to work 10-hour days from 7 a.m. to 6p.m. six days a week, Mondays through Saturdays, for up to three months. Construction may be noisy and require lighting for after-hours work. Improvements will include widening of the river bank, which also will be heavily armored to add stability and reconfigured to allow the public to sit and observe the river and the users of the water park.

9/17 River Sweep moves inland

Parks and Rec has 3 groups to “sweep” the area near the ponds and river so VPNA is going to shift our clean-up effort to in-land areas. We’ll be focusing on alleys and school grounds instead.

Meet at Idaho River Sports lot at 10am September 17th (this Saturday) till noon.  Please bring a few trash bags and a pair of gloves. Thanks.

Simplot Family will fund Construction of Park

Great news from an email sent from Friends of Boise Parks…


The Simplot family will fund construction of Esther Simplot Park and will launch the project next winter with facilities to support the adjacent Boise River Recreation Park, Boise Mayor David H. Bieter announced in his May 18 State of the City Address.

Mayor Bieter praised the Simplot family for moving forward to develop Esther Simplot Park, a 55-acre parcel along the Boise River west of Main Street. The Simplot family donated $1 million in 2003 to complete the purchase of the park. But its development had been considered a later phase after the River Recreation Park was developed and subject to additional fund raising.

The Simplots will move forward with a comprehensive master plan for Esther Simplot Park and will fund construction of the park. They will start next winter by building an access road, parking lot and restroom facilities in tandem with the River Recreation Park.

“This is one of the most significant donations in the history of the Boise parks system,” the mayor said. “And in addition to dollars injected into our local economy, it means that the redevelopment jump-start this area needs will happen that much sooner.”

Construction of Phase I of the Boise River Recreation Park will continue in the fall and is scheduled for completion spring 2012.  Phase I includes the rebuilding of the Thurman Mill diversion to include patented Wave Shaper technology.  Phase II of the park includes downstream water features and is in the planning stages pending agreements with downstream water users.
