Strategic Development Plan (SDP) [ NB: Ceased to have effect from 13 February 2023]

The SDP was a statutory planning document and had been a component of the development plan. It communicated strategic level and cross-boundary planning policy and applied national policy and guidance from the Scottish Government.

The SDP for Edinburgh and South East Scotland informed the Local Development Plans prepared by each of the Member Authorities in the Edinburgh and South East Scotland region which included West Lothian. The Planning (Scotland) Act 2019 however removed the need for the preparation of Strategic Development Plans and the adoption and publication of National Planning Framework 4 (NPF4) on 13 February 2023 was the trigger for all strategic development plans and any supplementary guidance issued in connection with them to cease to have effect. 

Strategic planning matters are now set out in the National Planning Framework 4 (opens new window)

The Planning (Scotland) Act 2019 has also introduced the concept of Regional Spatial Strategies (RSS) to provide a spatial representation of the key regional land use issues requiring to be addressed across a region identifying strategic development needs and priorities.

Although non-statutory in nature (they do not form part of the development plan and will not have a status in planning decisions), they must nevertheless be taken account of when a new LDP is being prepared.

West Lothian Council has worked collaboratively with a collective of former SESplan local authorities to prepare an Interim Regional Spatial Strategy for Edinburgh and South East Scotland City Region (opens new window) and it was submitted to Scottish Government towards the end of 2021.
