Some people find the idea of a website storing information on their computer or mobile device a bit intrusive, particularly when this information is stored and used by a third party without them knowing. Although this is generally quite harmless you may not, for example, want to see advertising that has been targeted to your interests. If you prefer, it is possible to block some or all cookies, or even to delete cookies that have already been set; but you need to be aware that you might lose some functions of that website.

Local Validation List

The following list should be used for all applications.

The South Downs National Park Authority ‘Advice to Homeholders and their Agents’ (August 2012) contains a ‘baseline assessment checklist’ that should only be used for  householder applications. The baseline assessment checklist should be completed accurately as the veracity and accuracy of submitted checklists will be checked and if further information is required it may delay determination of your application.

To assist with consultations and avoid delays 3 hard copies of all application documents and plans are required.

Local policy drivers are based upon the adopted development plans in the SDNP.  These policy drivers may change as emerging joint plans reach adoption.

For the purposes of the Local Validation List the definition and criteria for major development is as set out in The Town and Country Planning (Development Management Procedure) (England) Order 2015

Information Requirement from 9 February 2017 Guidance
Additional Plans The national requirements note the need for a location plan and “others as necessary” with the reliance on the local requirements to detail what those are. For the avoidance of doubt the local requirements should confirm what we need:

  • Block plan including site access details, scale bar, key dimensions (distance of the development from the boundaries of the site and size of the building), original paper size and a north point.
  • Existing and proposed elevations and floor plans in full
  • Existing and proposed site sections and finished floor and site levels and datum point (1:50 or 1:100) (In all cases where proposals involve a change in ground levels or is on a sloping site).
  • Roof plans (Required for all applications involving extensions to roof forms and new buildings).
