Attachment 1 - Information Request Response

                                                                                                                ingeniir


               By providing positive surface drainage in the rear of the lot to Opal Lane the development will
               have a beneficial impact on the neighbouring properties to the West.

          b. The existing impervious area in the rear portion of the allotment (fronting Opal Lane) is
             comprised of 2 sheds and paved landscaping around the pool area totaling 170m2. The proposed
             roof area of the new building is 160m2 hence is less than the existing impervious area to be
             removed as part of the development, as such will be non-worsening for stormwater runoff.

          c.   The development only proposes to redirect surface flows on the rear portion of the allotment to
               avoid draining to Opal Lane through the neighbouring property to the West; and will drain to
               Opal Lane directly as a result which is considered a beneficial outcome.



     5. Provide amended plans, prepared by a RPEQ, detailing the proposed roadworks, including
        but not limited to :
           a. Pavement design, including connection to existing concrete pavement, thickness,
               reinforcement, concrete strength, etc.;
           b. Stormwater discharge details, including scour protection, cross sections, etc.

          a.   Refer accompanying engineering plans revised to include the proposed pavement details
               matching that of the IPWEAQ standard RS-051 crossover. Details have been added for pavement
               connection to existing.

          b. The stormwater from the site is to discharge to a kerb adapter in accordance with IPWEAQ
             standards. The scour protection is provided by the pavement widening added to opal lane. Cross
             sections can be found on the standard drawings for the outlet.

If you wish to discuss this matter further, please contact Daniel Kenna.
