  • Assessment of land values to identify significant variances by location/development type;
  • Assessment of CIL rates including sensitivity testing based on values, use and location; and
  • Recommend CIL tariffs/rate to achieve an appropriate balance between delivering infrastructure and the impact on development viability.
