High-Level Summary
The Heritage Richmond Hill Committee meeting on September 5th focused on the repairs and restoration of the David Dunlap Observatory (DDO). Key participants included the Chair, Dr. Tuba from the DDO Defenders, Deputy Clerk, Dr. Ian Shelton, as well as consultants Chris Hall and Petra Frangy from Plus VG Architects.
Important Topics Discussed
David Dunlap Observatory Building Repairs (City File D12-07-228):
- The meeting included a comprehensive presentation focusing on the restoration work at the DDO, particularly the replacement of agult panels and repainting. Petra Frangy highlighted the poor conditions of some panels, prompting Dr. Tuba to inquire about long-term solutions: "What measures are proposed to avoid having these specific panels fail again?"
Condition Assessment and Replacement of Agult Panels:
- The condition of existing agult panels was discussed with a focus on why some panels deteriorated faster than others. Chris Hall explained why high-density fiberboard was chosen over homot material. Dr. Tuba questioned, "Might having more porous material actually be beneficial if there is moisture getting into the space between the Dome's outer or inner walls?"
Protection During Restoration Work:
- The safety measures to protect the Hillar spectrograph and 74 telescope during the restoration work were addressed. Chris Hall mentioned that an enclosure would be built around the telescope to prevent damage from falling debris. Dr. Tuba asked, "What measures are being proposed to ensure a set panel and other debris do not fall and damage the top of the 74 telescope while work is being conducted?"
Public Participation and Consultation:
- Although no written public submissions were received by the deadline, Dr. Tuba's late request to speak was accommodated. The chair's inclusive approach was noted as they suggested, "We could complete your delegation and then go back to you and bring staff in," emphasizing the committee's flexibility in public discourse.
Selection of Materials for Restoration:
- A detailed discussion about the merits of different materials for panel replacement ensued. Chris Hall stated, "The fibrex is a bit more rigid, it's a little more reliable in terms of being able to cut it, but it's still a breathable material." The decision to use high-density fiberboard over homosote was debated in terms of durability and moisture management.
Opportunities for Public Input
Although formal inputs through written correspondence and applications for electronic delegations were not received by the initial deadline, last-minute requests such as Dr. Tuba's to address the committee were accommodated. This indicates there may still be room for special considerations regarding public input under specific circumstances.
