Response to Information Request - 5 April 2018 · 132007.12.8

“Adamson Town Planning, specialising in providing higher order town planning advice”




       •   Provision of adequate maintenance access
       •   Retaining walls
       •   Likelihood of success of plantings necessary for pollutant removal with the shading likely
           over the basin.

  In relation to these issues, the following responses have been provided by TOD Consulting:

  Access to the bio basin will be provided at the eastern end of the basin. A concrete ramp will be
  provided instead of a blockwork wall at this end of the basin to allow for maintenance access.
  Details of this access will be provided as part of the detailed design and Operational works
  application.

  Retaining walls are required due to the limited space available after providing the number of car
  parks required for the site. Section 3.3.5.5 of the Water by Design Bio Retention Technical Design
  Guideline states that “bioretention systems should be designed without retaining walls, where
  possible ...” but does not state they cannot be used. Given the space constraints and the fact the
  basin is in a location generally not visible to the public, the use of retaining walls is considered
  to be appropriate in this situation.

  Advice of suitable plant species that are shade tolerant can be provided by a landscape
  designer/horticulturalist.

  The area of land and the design of the carparks required restricts the amount of land available
  and the location for the bio-retention basin. The shade tolerant plants to be provided in the
  bio-retention basin will be addressed in the subsequent application for operational works
  required for the development.

  In accordance with Part 3, section 13.2(a) of the Development Assessment Rules, the applicant
  has provided the further information requested and Part 3 is now complete (refer 15.1(b)(i)).
  Accordingly, it would be appreciated if Council would provide the adjoining owners details as
  soon as possible so that public notification for the ‘other changes’ application can commence
  in accordance with section 16.4 of the Development Assessment Rules.

  Should you have any questions with respect to the above, please contact me.

  Yours faithfully
