SOUTHLAKE -- The developers of Savannah Estates will ask Southlake and Westlake to adjust city boundaries to accommodate the proposed neighborhood.The majority of the 82-acre project, located west of Texas 114 on Dove Road, is in Southlake. But a 5.5 acre of land on the north side is in Westlake, said Bobby Dollak, an engineer for G&A Consultants. The developer wants to shift the boundary so the entire neighborhood is in Southlake.Southlake's city attorney is aware of the request but will wait until the City Council provides direction on the zoning, possibly in February, said Pilar Schank, city spokeswoman.Westlake officials will wait until Southlake makes a decision before deciding the matter, said Ginger Awtry, a spokeswoman for Westlake."It didn't make sense for us to begin a process taking any property away from Westlake until we know exactly what Southlake wants to do, so we are currently waiting to hear from them," Awtry said.The zoning change for Savannah Estates has been tabled multiple times to give the developer more time to meet with neighbors and make changes to the plan. The Planning and Zoning Commission is scheduled to vote on the zoning change and land-use amendment Feb. 7.Developers have cut the number of lots from 106 to 95, reducing the density from 1.4 units per acre to 1.2 units per acre on the Southlake portion of the project. Another dozen lots are proposed on the 5.5-acre tract that could be added to Southlake.Lots that border existing homes were enlarged to 30,000 square feet, increasing the average lot size from 19,700 square feet to 22,200 square feet, Dollak said.With bigger lots, the open green space has been reduced from 22 percent to 18 percent, still above the city's requirement. Dollak said more trees will be saved under the plan.The request is scheduled to go to the Planning and Zoning Commission Jan. 17. In addition to the zoning change, the developer is requesting a change in Southlake's land-use plan to allow medium-density residential. The land-use plan currently shows retail and low-density residential on the site.Sam School Road also could be realigned to make a four-way intersection with Peytonville Avenue that could become a future roundabout.A drill site about 600 feet north of the current Southlake border would still be in Westlake if the boundary change is approved.Range Resources drilled one well on the site in 2011, but a natural gas pipeline hasn't been connected to the site.Southlake doesn't allow gas wells within 1,000 feet of a protected use, such as a home, but the requirement doesn't apply across city boundaries.
