               Table 1, shows the current, proposed and change of the area over the basketball courts, of which
               drain to concrete spon drain, via eastern drain pipe to the exposed drain and overland flow to
               exposed drain the drain.

               The applicant was issued a further advice letter on 22 March 2021, regarding the hours of operation
               for the basketball court, whether the shade sail will alter the existing drainage catchments such
               that will result in scour within each receiving drain, and if the eastern drain was constructed and
               maintained as per the approved design. The applicant failed to provide an adequate response to
               the stormwater questions in the further advice letter. Council requested the applicant engage
               advice form the stormwater engineer that designed the existing system that the proposed shade
               sail structure will drain to. In turn, the applicant provided insufficient information to Council for what
               is considered to be a minor and resolvable issue.
               A new condition is therefore proposed to facilitate the installation of the proposed shade sails and
               as such will not overload the existing drainage system, thus generating scour, water ponding and
               mosquito breeding.
