OPW26-0055 - Response to Information Request
Project Ref: 260104 03 June 2026 Noosa Council PO Box 141 Tewantin QLD 4565 Attention: Daniel Epps Dear Daniel, Response to Council Information Request – Operational Works Address: 85 Gympie Street, Tewantin (Lot 51 on SP260161) Council Reference: OPW26/0055 Reference is made to the Information Request issued by Noosa Shire Council on 19/05/2026. In accordance with Section 13 of the Development Assessment Rules, this correspondence responds to Council’s Information Request in full and includes the following supporting documentation: - Attachment 1 – Amended Civil Engineering Plans, prepared by Lyndsay Consulting - Attachment 2 – Engineering Response to Information Request, prepared by Lyndsay Consulting Information Request Item 1 - Connection of Downpipes Lindsay’s Operational Works Stormwater Plan (22-0416-F22, Rev. E) dated 10 April 2026 details that the existing downpipes will be connected to the new drainage pipe. It is unclear to Council if these downpipes will connect directly to the new sealed pit or to the captive relief line. Council suggests that the head losses from connecting to the captive relief line wouldn’t allow flows from the downpipes to discharge to Gympie Street and would discharge via the level spreader to the downstream property.
