Phased development in new subdivision construction limits soil exposure and reduces runoff and off-site erosion. A master development plan is created to show the parcelization, utilities, and roadway layout. The plan divides the site into distinct portions with only one portion cleared at a time and roadways constructed only in the current phase. When a percentage of the lots is sold or built upon in the first phase, the next construction phase begins. Successful phased development depends on the site’s topography and size.
