    3. Provide preliminary engineering designs of the access driveway to the house sites on
       Lots 2 & 3 and the associated storm water system. The designs must be based on
       the flood modeling of the site and be in accordance with QUDM providing for safe
       access for pedestrians and vehicles.

    3. Please refer to plans 1707-01E, 1707-03A, 1707-04A, 1707-05A showing layout
       and long/cross sections for lots 2 and 3. The designs are based on site flood
       modeling, refer to BSM report dated 21-2-18 section 3.6 page 12 showing safe
       access and QUDM compliance. The velocity of flow and depth adjacent to
       driveways is very low.

Access and Frontage Works

    4. Provide additional detail (comment and plans) in regard to:
          a. The suitability of the access to Lots 2 & 3 including sightlines and services.
          b. The proposed access points for Lots 1 & 4.
          c. The extent of frontage works (kerb and channel, footpath, road widening)
              proposed by the applicant.

    4. Please refer to the following:
          a. The access for lots 2 & 3 was checked on site for adequate sight
             visibility, refer to plan 1707-1E and notes below.

                In the southbound approach to lot 2/3 driveway along Church Street,
                cars stop at the intersection to cross Red street or turn into Church
                street resulting in a low speed entry. We estimate southbound approach
                speed to be 45km/h based on this and the speed environment of the
                street. Based on AS2890.1 the required sight distance is 35m (domestic
                minimum) to 40m desirable. With removal 2-3 of small trees that are
                growing out on and angle towards road (see Figure 1 below
                approximately 75mm diameter) there is 70m southbound visibility to
                driveway which is above requirements. These trees will require clearing
                for future footpath, and path will ensure sight visibility is maintained in
                future.

                The northbound approach has excellent visibility with 200m sight
                distance.

                Council policy prefers that driveways are located away from existing
                services when possible. We have moved lot 2/3 driveway to avoid an
                existing fire hydrant in the road reserve. Driveway finished level is at or
                slightly above existing so there is no impact on cover to existing
                services.
