- Sustainable Development - During the past decade there have been a number of Government policy initiatives of fundamental importance to development plan preparation. The United Kingdom has embraced the principle of sustainable development based on stewardship of the environment and has widened the concept to embrace economic and social considerations. Development to satisfy the requirements of today’s society should not compromise the potential for future generations to satisfy theirs. Consequently, development plan policies and proposals will be subject to Strategic Environmental Appraisal. This means proposals for new development will be assessed against the availability of supporting infrastructure and the ability of the environment to support the proposal.
