16. Abstract
The roadside represents the interface between the roadway and the surrounding environment, and plays an important role in protecting the larger ecosystem. Roadsides are dynamic environments that require unique treatments and restoration approaches. This guide presents an integrated and holistic approach to incorporating sustainable solutions into disciplines such as hydraulic design, geotech, aesthetics and vegetation, among others. The intent of this research is not to create a new design process, but rather to incorporate recommendations into the existing design process. The goal is to raise awareness about the trade-offs inherent in designing a sustainable roadside so that these issues are addressed early-on in project development. A checklist of sustainability strategies is included in this guidebook as a tool within the project development process.

CONTEXT SENSITIVE
SOLUTIONS
Context sensitive solutions (CSS) is a collaborative, interdisciplinary approach that involves all stakeholders in providing a transportation facility that fits its setting. It is an approach that leads to preserving and enhancing scenic, aesthetic, historic, community, and environmental resources while improving or maintaining safety, mobility, and infrastructure conditions (FHWA, 2007).
ENGINEERING The profession in which knowledge of mathematical and natural science is applied with judgment to develop ways to utilize, economically, the materials and forces of nature for the benefit of mankind (Accreditation Board of Engineering and Technology, 1963).
HIGHWAY Any facility designed to accommodate motorized vehicular transportation. This includes all functional roadway classifications (arterial, collector, local) that accommodate motorized vehicles (FHWA, 2012).
RESTORATION The return of an ecosystem to a close approximation of its condition prior to disturbance (NRC, 1995).
ROADSIDE Roadside includes the sides of the road beyond the pavement (travel lanes and shoulders). The area includes the limits of the right-of-way and may extend beyond the right-of-way if public land. The roadside is typically an area disturbed by roadway construction or reconstruction.
SUSTAINABILITY Sustainability is satisfying basic social and economic needs, both present and future, and the responsible use of natural resources, all while maintaining or improving the well- being of the environment on which life depends (FHWA, 2011).
SUSTAINABLE DEVELOPMENT With respect to development, the Brundtland Commission of the United Nations succinctly stated that sustainable development is "development which meets the needs of current generations without compromising the ability of future generations to meet their own needs" (United Nations, 1987).
SUSTAINABLE HIGHWAY FHWA views sustainable highways as an integral part of the broader context of sustainable development. A sustainable highway should satisfy the functional requirements of societal development and economic growth while reducing negative impacts on the environment and consumption of natural resources. The sustainability of a highway should be considered throughout the project lifecycle - from conception through construction (FHWA, 2011).
SUSTAINABLE SOLUTION A sustainable solution is a specific project activity, feature, or process that accomplishes the goal of promoting sustainability.
