Does the application involve more than one culvert?
        Yes         - generate another section 5 response for each culvert and submit with the application.
        No          - if the application involves another type of barrier identified in section 3, go to the relevant
                      section identified.
                    - if the application does not involve another type of barrier identified in section 3, go to section 7.

6.    Constructing a new or modifying (including maintenance and replacement) an existing waterway barrier
      except those listed in sections 4 and 5.

What is the nature of the proposed work?                                                             Construction of a new barrier
