COLLEYVILLE -- A zoning change for 48 zero-lot line homes at Glade Road and Bluebonnet Drive will require a super majority -- at least 6 votes -- to pass if it goes to City Council Feb. 5.The super majority is required because the Planning and Zoning Commission denied the proposal with a 4-2 vote on Jan. 14.More than 20 percent of the property owners within 200 feet of the site submitted letters of opposition, which would impose a super majority anyway.They cite concerns about traffic, density and drainage.For the second time in two months, commissioners directed developer Paul Spain to cut the density to The Preservation at Glade so it transitions better from the zero-lot line homes in the Bridges of Riverwalk to the estate lots to the east.The original proposal with 50 lots was tabled in December, so Spain cut two lots and shifted the northern entrance so it doesn't line up with Cherry Street. He made the changes based on feedback from neighbors and commissioners."We are sensitive to their needs," Spain said. "We've gone through every hoop and hurdle."But it wasn't enough to convince the commissioners to support the zoning change from 1.8 units per acre to 3.99 units per acre."My problem from the beginning has been the zoning," said Commissioner Don Davis. "Why would we double it?"When Dan Winters purchased his acreage and home, he studied the nearby zoning, including this 12-acre tract that was zoned for 20,000-square-foot lots."That's something I examined in detail, the city's plans for zoning in our area," Winters said. "We counted on that when we moved here. If I had known that the zoning could be rezoned so easily....with a couple meetings we might have reconsidered."Spain said he couldn't go any lower on the density because of the price of the land."This many houses is going to add too much traffic to poor little old Bluebonnet Drive and to Glade Road before it's over with," said Linda Baker, who lives to the east.Spain defended the project, citing a traffic study that showed minimal traffic increase during peak periods.The luxury homes would sell for $200 or more a square foot, Spain said, adding that he could provide comparable prices to prove it. These types of homes are in demand and don't stay on the market long."The people that buy those houses want them done nice," he said.Matt Quinn, who lives in the Bridges at Riverwalk, called that a "pipedream," saying lower density would be better for property values. He also questioned the traffic study results."Never trust the words of a paid advocate," Quinn said. "So, Mr. Spain, if you paid for that traffic study you were ripped off."Resident Lisa Pomroy said Colleyville is known for having big lots and low density."People moved to Colleyville because of what Colleyville is," Pomroy said. "They don't want to move to a subdivision that's got small homes. I'm sorry he may not make the amount of money that he wants."The commission's first vote to approve the project deadlocked 3-3, with Commissioner David Wheelwright absent. Chairman Jeff Byerly said he supports the project but voted to deny it on the second vote to break the tie.
