Thames Basin Heaths special protection area SPD
Read the Thames Basin Heaths SPA Avoidance Strategy 2017 SPD (PDF) [9MB]
The Special Protection Area Strategy contains guidance for developers whose work could impact the Thames Basin Heaths SPA. It sets out restrictions for developments that could directly harm the SPA, and mitigation schemes for new residential development. These mitigation schemes are:
These mitigation schemes are:
- Suitable Alternative Natural Greenspaces (SANGs) - new open spaces that attract visitors away from the SPA, and;
- the Strategic Access Management and Monitoring (SAMM) project, which mitigates the impact of SPA visitors
SANG and SAMM are funded by tariffs that are based on the average number of people living in homes of different sizes.
The tariffs are updated every year at the end of March to take account of inflation. See the annual tariff update.

This document should be read alongside the SPA strategy. It changes the strategy by:
- updating the occupancy rates for new homes using data from the 2021 census
- changing the SANG and SAMM tariffs using the new occupancy rates
- changing how tariffs are applied to Houses in Multiple Occupation (HMOs)
- clarifying how tariffs are applied to residential caravans and temporary developments.
