Minor Change Report 132001 210127 4 · 132001.210127.4

               Existing Condition 35
                      35.     Roof runoff from any new buildings shall be directed to a rainwater storage system or
                              tank (minimum storage capacity equivalent to 20 litres/m2 of new roof area or greater)
                              that is plumbed to service the toilets in the new building and landscaping areas. The
                              design of the rainwater storage system shall be to the satisfaction of the Manager
                              Plumbing Services.
               Applicant’s Request
               The applicant requests the condition be updated to reflect current standards and most recent
               documentation provided. The applicant has requested condition 35 be amended to read:
                      Stormwater runoff from the development must be connected to a lawful point of discharge
                      without causing scour or damage to the subject site or any adjoining properties. The works
                      must be undertaken in accordance with an Operational Works approval and be generally in
                      accordance with STP Consultants’ Stormwater Layout Plan (SKC01) dated 21 March 2023
                      and (SCK02) dated 20 March 2023.
               Assessment of Request
               Council’s Senior Development Engineer has reviewed the request and stated that the proposed
               change to condition 35 is repeated as part of existing and proposed condition 58 (addressed
               below). To avoid doubling up on conditions, engineering recommends that condition 35 is deleted.
               This achieves the intent of the request and ensures that all stormwater runoff from the proposed
               development is managed in accordance with the most current stormwater management plan.


               Existing Condition 36
                      36.     To ensure that polluted run-off does not enter Council’s stormwater drainage system
                              or nearby creeks, stormwater run-off from the carparking areas and the driveways shall
                              have the first flush (the first 12 mm of rainfall or hose-down) collected in a grease/oil
                              arrestor provided on site prior to being permitted to discharge from the site.
                              All other clean stormwater, such as roof water, can bypass the grease/oil arrestor.
                              To this end, a detailed maintenance plan shall be prepared for the proposed grease/oil
                              arrestors, which shall be submitted to the Council for approval prior to obtaining a
                              Development Permit for Operational Works.
                              The approved maintenance plan shall be incorporated in the Management Plan for the
                              development and a copy of this shall be provided for Council’s records prior to
                              commencement of the approved Use.
                              A Development Permit for Building Works shall not be granted until a Development
                              Permit for Operational Works has been issued in regard to the drainage scheme.
               Applicant’s Request
               Condition 36 ensures that pollutants do not exit the site via the stormwater network.
               Assessment of Request
               Council’s Senior Development Engineer has reviewed the request and stated that condition 36
               refers to the treatment of stormwater captured within existing parts of the development that are not
               ‘included’ as part of this proposed development (i.e., carparking areas, driveways, etc.). The
               applicant’s request to substitute condition 36 with condition 58 would result in the existing areas of
               the development being ‘excluded’ from stormwater quality treatment. The applicant made it clear
               that the only changes to stormwater management was to the area of the proposed development.
               Therefore, to ensure the existing areas of the development are treated appropriately, it is
               recommended that the request to amend condition 36 be refused and condition 36 remain as is.
