All of the land in Christchurch's central city has been cleared for rebuilding on, although some areas may require more foundation or ground work.
After months of uncertainty, the geotechnical report by engineering consultants Tonkin & Taylor says "no areas within the CBD or adjacent commercial areas were identified as having ground conditions that would preclude rebuilding on those sites".
The report - which is part of the final draft Central City Plan which will be adopted by the Christchurch Council tomorrow - does point out that "more robust foundation design and/or ground improvement may be required".
But Christchurch Mayor Bob Parker has applauded the timing of the report, saying it would give land and property owners much more certainty and confidence, know that they knew their sites were suitable for rebuilding.
"As we had originally thought, detailed and comprehensive ground investigations and geotechnical assessments will still be required for individual sites before owners can begin their developments."
