               Reconfiguring a Lot Currency Period
               2.     This development approval lapses if the requirements of the conditions have not been
                      completed and an application for plan seal is not lodged with Council by 4 September 2029,
                      unless an application to extend the currency period is approved by Council.
               Operational Works Currency Period
               3.     This development approval lapses if the use has not happened by 6 September 2031, unless
                      an application to extend the currency period is approved by Council.


               Preliminary Approval Condition 3 (3.1-3.4)
               Prior to Council issuing a Development Permit, provide an amended Stormwater Management
               Plan and associated Engineering Drawings that incorporates an allowance for climate change in
               accordance with Performance Outcome 2 of the Water Quality and Drainage Code. The amended
               package must include amendments to Engeny’s Stormwater Management Plan and associated
               Engineering Drawings prepared by TOD Consulting, be prepared by a suitably qualified person
               (RPEQ), and include in particular:
               3.1 - allowance for a 20% increase in rainfall intensity by the year 2100 for all modelled scenarios
               (10% and 1% AEP event);
               3.2 - a revised assessment of non-worsening based on like-for-like scenarios for climate change
               scenarios, based on the 1% AEP event (2100);
               3.3 - revised internal site drainage drawings and calculations to include a climate change
               allowance; and
               3.4 - additional detail demonstrating how the “gap flow” has been calculated – nothing that Section
               4.1 of the Stormwater Management Plan suggests that development flows in excess of the pipe
               network fail to report to the existing bioretention basin in Ely Street.
               Applicant’s Request
               The applicant has requested Preliminary Approval Condition 3 be deleted.
               TODs development engineers provided updated engineering and stormwater management plans,
               incorporating minor modifications to the stormwater calculations sheet. It is also recognised there
               are no requirements to increase any pipe sizes of the building.
               Assessment of Request
               Council’s Senior Development Engineer has had the amended Stormwater Management Plan and
               associated Engineering Drawings peer reviewed by a suitably qualified third party.
               As a result of this peer review, further changes were recommended by the third party engineer and
               these changes with be integrated into an amended Stormwater Management Plan, which is
               recommended to be provided to Council (by a condition of the development permit), prior to
               requesting the required pre-start meeting associated with the Operational Works permit.
               Recommendation
               It is recommended Preliminary Approval Conditions 3.1-3.4 be deleted and the following condition
               be imposed, requiring the applicant to submit the amended Stormwater Management Plan, prior
               to requesting a pre-start meeting.
               Recommended Condition
               Prior to Council attending the prestart meeting, submit and have approved by Council, an amended
               revision of Engeny’s Stormwater Management Plan (BBNE00529_0002_0001-REP-001-2) to
               include the following amendments:
                      a.      provide clarification on Section 4.1 with respect to the modelling of the proposed
                              detention tank within the townhouse site and gap flows that do not report to the existing
                              detention basin.
                                                                                                       Page 11 of 39
