Unique opportunities are presented when the civil engineering and landscape architecture are integrated. While ensuring that the site is functional in terms of earthwork, vehicle movements and utilities these same requirements can be provided in ways that bolster the financial, aesthetic and ecological roles of the site as well. For example utilities can be sited to avoid tree roots, site grading can be specified to accent the buildings, walkability can be promoted within the parking plan and building locations can be optimized for generating positive streetscapes.
