Cross Timbers Conservation Dev. District


The Cross Timbers Conservation Development District (CTCDD) is predominantly residential development, typically being single family residential development on two-acre lots or greater in combination with conservation easements and/or other conservation techniques that preserve the Cross Timbers ecosystem and other natural systems. Currently, the Town’s Master Plan does not provide sewer to the CTCDD.

  • Urban Ecosystem Analysis: In 2006, American Forests conducted an Urban Ecosystem Analysis of Flower Mound to demonstrate the ability of the Town’s tree canopy and other “green infrastructure” to provide air and water ecosystem services. This project provided the Town with tools and data to utilize green assets as part of an overall land development approach. This ecosystem approach improves the quality of life in the community while lowering the costs of managing its built infrastructure. The project quantified the ecosystem benefits of the Town as a whole and also modeled the impact of two different land development approaches: conventional vs. conservation development. The Sanctuary conservation development site was used to conduct the comparison.

  • Conservation Development Illustration: These graphics offer a simplified illustration of two-acre total site development versus one-acre, and half-acre conservation development. The Town’s Master Plan currently allows residential development within the District under two options: 1) Two-acre total site development (building houses on two-acre lots for an entire site), or 2) conservation development which allows one acre lots with 50% of the land preserved as open space. We hope these graphics help illustrate the discussion points on using conservation developments to preserve open space.
    • For each example, the illustrated property is 100 acres. The residential density for each example is expressed as “gross density.” This term is broadly used to describe the total number of residential units divided by the total acreage of a development. In the District, the gross density of any project is one unit per two acres. For example, a 100 acre project in the District can have a maximum of 50 residential units. This gross density can be accomplished by total site development of two-acre lots (50 units), or by a conservation development of one-acre lots (50 units) with 50% of the land preserved as open space.
