(Georgetown) - The Habitat for Humanity of Greater Georgetown is laying the foundation for its largest project ever. The nonprofit started construction this month on a 20-home site that it hopes to complete within three or four years. Dubbed Old Mill Village, the project sits on land formerly occupied by a cottonseed oil factory, closed in 1961. Owners of the Old Mill property donated the three-acre site to the Georgetown Habitat in 2004. Since that time, the group has spent about $300,000 preparing the site for homes. Through partnerships with the City of Georgetown, Williamson County and private businesses, Habitat has put in sewer and water lines, curbs and sidewalks. Once Habitat finishes the project, the nonprofit expects the site to be worth about $2 million. It will comprise a mixture of one- and two-story homes, each having three or four bedrooms. So far, the group has started on three homes; two others are working their way through the permitting process. Each has a sponsoring team, which raises $50,000 in construction costs. Habitat then sells the homes (at a steep discount) to families who assisted in the building of the homes but who have recently faced adversity: such as Hurricane Katrina victims. By laying advance groundwork, the Habitat can jump straight into its next project, on land already donated by the Georgetown-based W.D. Kelley Foundation. That site will likely hold 12 to 18 new homes.
