Development Roads. Roads built for real estate subdivision vary in quality from the crudest pioneer
type to city streets. Differences depend on the type of development, local regulations, value of land,
capital available for improvement, terrain, and other factors.
Rural subdivisions are seldom regulated, but those in and near cities may have to have roads built
to high standards. However, the developer may be allowed latitude in locating roads, or shifting
them to avoid obstacles, to run cuts through banks of desirable fill or gravel, to change lot lines,
or to obtain a more attractive appearance.
