Special Protection Areas (SPA)

Thames Basin Heaths Special Protection Area (SPA) - around Farnham

The Thames Basin Heaths SPA covers an area of 8274.72ha across Hampshire, Berkshire and Surrey. It forms part of a complex of heathlands in Southern England, which support important breeding bird populations, including the Dartford Warbler, Nightjar and Woodlark.

More general information on Special Protection Areas (SPA) is available from Natural England.

The SPA affects most of Farnham

About 80ha of the Thames Basin Heaths SPA is within Waverley to the north of Farnham. There is a 5km buffer zone, however, and therefore the SPA affects most of Farnham. View a map showing the areas covered by 5km buffer zone.

Avoidance Strategy - Suitable Alternative Natural Greenspace (SANG)

An Avoidance Strategy was adopted in 2009 so that any new housing development in the Farnham area would not have an adverse impact on the SPA. 

This provides an additional 3.45ha of SANG (Suitable Alternative Natural Greenspace) in Farnham Park. This SANG was made available following the adoption of the Farnham Design Statement as a material planning consideration on 20 July 2010.

Following the Executive's decision to release the remaining 6.9ha of SANG at Farnham Park, the Thames Basin Heaths Avoidance Strategy was updated in May 2013 to reflect this change.

Submitting a planning application within 5km buffer zone in Farnham

If a developer cannot provide the open space, they may be able to pay a SANG tariff to contribute towards the enhancement of existing semi-natural open space, where such sites have been identified by the local authority.

In Waverley, financial contributions to the enhancement of Farnham Park as SANG will need to be secured through a Section 106 unilateral undertaking.

An appropriate Section 106 unilateral undertaking must be agreed before we can grant planning permission. 

Proposals for residential developments that do not secure the provision of SANGs will be unlikely to survive an Appropriate Assessment, meaning permission must be refused.

How much is the SANG tariff?
