Unitary Development Plan and Supplementary Planning Guidance

The current adopted Development Plan for the Gwynedd Local Planning Authority Area is the Gwynedd Unitary Development Plan (UDP).

Following a lengthy preparation process, including a Public Inquiry and the publication of the Inspectors report (2007) Gwynedd Council formally adopted the UDP in July 2009.

The main objective of the UDP is to ensure sustainable development and to create favourable circumstances to protect, support and develop our communities – culturally, environmentally and economically.
