Monday, the Flower Mound Town approved a concept plan for improvements at Rheudasil Park, but it postponed a decision about how to address the pond's dredging and bank stabilization.
The council voted for Option “B” that calls for a park redesign, as opposed to a park revitalization.
Highlights of Option B include a larger playground area with new equipment for 2- to 5-year-olds and 5- to 12-year-olds. Also, the playground would be connected to the pavilion, and both would be moved to the north side of the park, near the southwest intersection of Forest Vista Drive and Lake Forest Boulevard. They would both face the pond.
The restroom, which was a source of debate earlier this year, is proposed to be on the north side of the pavilion.
The park will feature, from south to north, open space, a new and slightly larger basketball court that would be designed for middle-school aged children, a plaza with benches, the existing memorial plaque and the playground/pavilion area. There would also be a widened sidewalk and a new entrance sign.
There will be a perimeter fence would be installed around the playground and pavilion.
Option “B” is projected to cost $1.2 million. Option “A” cost $989,200 but didn't have the playground and pavilion grouped together.
“I liked Option 'B' because of the placement of the amenities,” said Deputy Mayor Pro Tem Mike Walker, noting the alignment for the playground, pavilion and restrooms for visibility and safety.
The council balked at the dredging plan, which cost $2.7 million for the mechanical dredging option at the Rheudasil Park pond, as well as the two smaller ponds just to the north. Hydraulic dredging cost $4.1 million.
Officials from Freese and Nichols consulting firm said dredging is needed to remove 27,000 cubic yards of sediment that has gotten into the pond over the years. They said the pond's depth has decreased from a range of 2 feet to 14 feet deep to a half foot to 10 feet deep.
“You need a depth of 6 feet to 12 feet to sustain aquatic life,” said Kelly Dillard, of Freese and Nichols. “You don't have that now.”
Dillard said a full dredge of about 14 feet would keep the pond from having significant erosion or sedimentation.
The council wanted a place for aquatic life but was concerned about the price tag.
“We want it, but do we want to pay that much for it?” said Councilman Mark Wise. “Maybe our Kid Fish event can be moved to Twin Coves Park.”
The bank stabilization was postponed since it goes hand-in-hand with the dredging. Pricing options ranged from $468,400 for a revetment armoring to an articulated concrete block, which cost $999,900. A structure wall costs $918,200.
Officials from Freese and Nichols said the stabilization is needed because the pond's bank has lost as much as 10 feet in the southern area because of erosion.
The cost for Option “B”, mechanical dredging and revetment bank stabilization was $4.4 million going with the Parks, Arts and Library Services (PALS) Board's recommendation last month.
The town staff will research various dredging options, and the item will be brought back at a future meeting.
The council also approved a phasing plan for Heritage Park at Flower Mound. With Phase 1 already complete, the cost for phases 2-4 is projected to be $4.8 million.
Phase 2 is expected to include the dog park, a pond, sculptures, picnic stations, parking spaces and a sidewalk.
Phase 3 will include a bio-swale, a splash pad, a restroom facility, a sidewalk, a rustic pavilion and parking spaces.
Phase 4 will feature a nature trail, a plaza, a waterfall, a scenic overlook, sculptures, a trail and an 18-hole disc golf park.
