Modeling Scenarios for Flower Mound

Article excerpt

The the town of Flower Mound, northwest of Dallas, Texas, has designated two conservation developments, residential projects that cluster dwelling units on smaller lots than are currently zoned to protect and preserve open space. The goal is to "preserve open or natural lands as an integral component of the development." One, the Sanctuary site, was used to demonstrate the ecosystem benefits of conventional vs. conservation development land planning. An Urban Ecosystem Analysis prepared by AMERHMN FORKSTS used data from newly acquired 2006 satellite images and compared them to the site's condition in 2001.

Using CITYgreen, AMERICAN FORESTS modeled two land development options-first, comparing lot size (1/2 acre vs. 1 acre) to the ecosystem benefits of the preserved open space and tree cover when the number of lots remains the same. The second examined built lots, and how the proportion of tree canopy, open space, and impervious surface affects ecosystem benefits to the site as a whole.

Because less tree canopy and open space were preserved under the conventional development scenario, this site would require an additional 27,000 cubic feet in storm water management, valued at $54,000 when compared to the conservation development site. …
