SOUTHLAKE--A huge retail project and two new neighborhoods will be considered by the Planning and Zoning Commission Thursday night at 6:30 p.m. at Town Hall, 1400 Main St. If approved, the City Council would have a first reading on the three proposals at its Dec. 4 meeting with a public hearing and second vote in January.Williamsburg EstatesWilliamsburg Estates is asking permission to build 33 homes on 25 acres between Kirkwood Boulevard and Texas 114 just north of the Verizon headquarters. The project requires a zoning change. The density would be 1.3 units per acre. The plan shows 31.7 percent open space, including a trail that follows a creek on the north of the site.The houses would start at $750,000 and would go up to $1.1 million, said Bobby Dollak, an engineer with G&A Consultants.Some neighbors criticized the density of the project at the Southlake Program for the Involvement of Neighborhoods (SPIN) meeting last month. They're concerned that the smaller houses won't sell for what the developer is asking and that could affect home values in their neighborhood.Gabriella Miller said she is glad houses are going in next to her neighborhood in Kirkwood Hollow rather than commercial development."We just want to make sure they don't negatively impact our pricing," Miller said.Dollak said they're building the type of house Southlake buyers want and builders will build. They chose smaller lots so there could be more public space.Highland OaksA new proposal for Highland Oaks comes back to the Planning and Zoning Commissioner after the City Council told the developer, Terra Land Management, to make changes to the original plan. The original proposal had 15 lots on 9 acres at the northwest corner of Highland Street and White Chapel Boulevard.It also included a request to amend Southlake's land-use plan to allow medium density residential. Council members were not willing to increase the density in this case because they want the area to remain low density.The developer has argued that the widening of White Chapel Boulevard and the construction of a two-lane roundabout at the intersection of Highland Street makes low density less likely.Southlake Park VillageSouthlake Park Village would have 220,000-square-feet of retail shops and restaurants at the southwest corner of Southlake Boulevard and Carroll Avenue. The project would also feature fountains and other water features throughout.The proposal includes buildings of all sizes from 22,000-square-foot anchors to a 14,000-square-foot grocery store, though no tenants have been announced.
