Officials said there are currently 11 homes in the Richmond Hill subdivision still within the investigation site. Once investigators complete their assessments, the Department of Code Enforcement will inspect those homes to determine whether they need demolition or require repairs.
Approximately 200 residents were evacuated from their houses following the blast. During a briefing Monday, investigators stated 29 of the 80 affected homes remain uninhabitable. Some homeowners were allowed to return to their homes Monday in order to survey the damage with insurance adjusters.
Tuesday, the National Transportation Safety Board and Citizens Energy announced their tests indicated there was no evidence of natural gas leaks in the lines or valves leading up to the epicenter of the blast.
The official cause of the blast is still being investigated.
