Attachment I - Updated Engineering Report & SWMP

       Refer to preliminary infrastructure drawings in Appendix B for service
       connection locations.

       4.3    Electricity and Telecommunications

       Power and telecommunications are both available from Doonella Street
       overhead network.


5.0    ACCESS

Access to the site will be via two separate commercial crossovers from Doonella
Street into on-grade car parking, located in a semi-basement ground floor.

Carparks, ramps and parking aisles internal to the site have been designed in
accordance with AS2890.1 – ‘Off Street Parking’.

On-grade car parking is proposed to provide necessary off-street car parking.
Refuse collection is proposed from the North-west corner of the site in Sidoni Lane,
as requested by Noosa Council.


6.0    STORMWATER MANAGEMENT

       6.1    Legal Point of Discharge

       The subject site currently discharges to Doonella Street, the sites legal point
       of discharge. In order to replicate existing conditions with regard to
       stormwater runoff it is intended to pipe 100% of roofwater and podium
       surfaces to a rainwater detention and reuse tank positioned in the eastern
       side of the carpark. Roof water and podium drainage collection will be
       sized to convey up to and including a 1% AEP event.

       The tank will ensure non worsening flows in order to maintain the existing
       stormwater properties of the site. This flow will be released via detained
       orifice flow from the rainwater detention tank and piped to the existing
       stormwater infrastructure along Doonella Street. Environmental flows will
       be directed to a Bioretention Basin to ensure reduced pollutant loads are
       satisfied as per Water by Design targets (Appendix A – WSUD Design
       Objectives for Queensland).

       There is a small catchment of the site that bypasses the bio retention basin
       due to site levels. It is proposed that the bypass area be treated using
       landscaped swales. Refer to Appendix C - MUSIC Model for detailed swale
       properties.
