 The Plan is out of date;

 Whether there have been changes in the site viability since the time of

Plan;

 Whether there are ‘particular’ circumstances which would seem to
warrant a site specific assessment.

Otherwise Para 57 states that where plans are up-to-date, applications that

comply with them, should be assumed to ‘be viable’.

3.2 Policy – Mix Sussex District Council

Policy 31 of the District Plan states that 30% affordable housing should be
provided on site for all residential developments providing 11 dwellings or
more, or a maximum combined gross floor space of more than 1,000 m2.

The provision should be made on-site. A mix of tenure, normally
approximately 75% social or Affordable Rental homes, with the remaining
25% for intermediate homes, unless the best available evidence supports a
different mix; and free serviced land for the Affordable Housing.

In addition, there are three SPD documents that are of relevance:

 A Development Infrastructure and Contributions SPD, which sets out the

overall framework for the management of planning obligations;
 An Affordable Housing SPD, which provides more detailed information

on the requirements for on-site and off-site affordable housing
provision, and;

 A Development Viability SPD which provides information on the
viability assessment process, and sets out the District Council’s
requirement that, where developers believe the requirements make

their proposed development unviable, a viability assessment much be
submitted to the District Council with supporting evidence for approval.

The characteristics of a site and the development as a whole should be
reflected in the affordable housing mix – dwelling tenure, type and size.
This is likely to be approximately 25% 1B/2P, 65% x 2B/4P and 10% x
3B/5P units in accordable with affordable housing need.

The guidance states that where an application does not meet policy
requirements for affordable housing, a viability assessment must be
