L2NC - Information Request Response

   Item 2 – Provide a construction method plan for these retaining structures that does not contemplate
   the use of vibration equipment (either for sheet pilling or soil compaction).

   Response – Per Drawing no. 192297-C001 within the updated Engineering OPW Plans included at
   Attachment 2, the retaining walls will no longer utilise sheet pilling and as such vibration equipment
   will not be required. It is noted the retaining wall on the western boundary is now proposed to use a
   block masonry type wall which will be constructed incrementally along the boundary in order to avoid
   any nuisance to the adjacent property. Further wall detail is included within the Technical Note
   prepared by Tectonic dated 4 February 2021 which is included in Attachment 6.

   Item 3 – Ensure that no structural elements, whether temporary or permanent, extend into
   neighbouring properties. Alternatively, provide neighbouring properties owners’ written consent,
   allowing to do so.

   Response – The updated Engineering OPW Plans included at Attachment 2 and updated Landscape
   OPW Plans included at Attachment 3 confirm that no structural elements extend into neighbouring
   property and are wholly contained within the subject site.

   Item 4 – Provide Unity Water’s approval for the proposed works over and adjacent to the sewer line.

   Response – As requested by Council, Unity Water’s Concurrence Agency Referral Response including
   conditions for the proposed works over and adjacent to the sewer is included at Attachment 5.

   Item 5 – Provide amended plans detailing, but not limited to, the following information:
      5.1 proposed retaining structure (material foundations, etc.), ensuring that no works are
           undertaken on the neighbouring property;
      5.2 a section plan indicating the location of the walls and foundations in relation to the property
           boundary and finished floor levels;
      5.3 the structures required to collect and convey existing overland flows that are impacted on by
           the construction of the retaining structure;
      5.4 any fencing to be installed on top of or beside the retaining structure;
      5.5 the location of any services, above or below ground, adjacent to the proposed retaining
           structure.

   Response – As request the updated Engineering OPW Plans included at Attachment 2 have been
   amended accordingly to reflect the detail of the proposed retaining wall along the site’s western
   boundary per Drawing no. 192297-C120. It is noted the existing neighbouring retaining wall at the
   north-western corner of the site will remain per Drawing no. 192297-C100 and the proposed building
   wall will be used for retaining. As detailed by the updated Stormwater Management Plan included at
   Attachment 4 there is no existing overland flow in this location and as previously confirmed no works
   will be undertaken on the neighbouring property. The existing fence in this location will also remain.
   Any relevant services have been included into the amended plan set.
