4.2.8 Bridges

4.2.8.1 Permitted Activity Rule – Bridges

Exception

This Rule does not apply to:

Plantation forestry activities as from 1 May 2018 these activities are regulated under the National Environmental Standards for Plantation Forestry Regulations 2017(external link).

 

  1. Unless controlled by Rule 4.2.5.1 the use, erection, reconstruction, placement, alteration or extension of any single span bridge not exceeding 10 metres in length, and necessary bed disturbance, in, on, under or over the bed of any river, and
  2. Any discharge of sediment associated with construction activities; and
  3. Any deposition of necessary construction materials

are permitted activities subject to the following conditions:

  1. Any such bridge shall be designed so that a two percent annual exceedance probability (1 in 50 year) flood event shall not cause any increase in upstream water levels which causes flooding on neighbouring properties.
  2. The soffit (underside of the bridge beams) of any bridge shall be at least 0.5 metres higher than the top of the banks of the river bed, or at least 0.5 metres above the two percent annual exceedance probability (1 in 50 year) flood, whichever is the lowest.
  3. The waterway area of the river bed shall not be reduced by more than 10 percent. Reduction of the floodplain area shall not exceed 10 percent.
  4. The construction works shall comply with the suspended solids discharge standards as set out in Section 4.2.21.
  5. The waterway area of the river bed and floodplain within five metres of the structure shall be maintained clear of debris.
  6. The bridge shall be fixed in place or constructed to prevent it being washed away in the event of a flood.
  7. The structure shall be maintained in a structurally sound condition at all times.
  8. All materials and equipment used shall be removed from the river or lake bed and floodway and the floodplain on the completion of that activity.
  9. No contaminants (including, but not limited to, oil, hydraulic fluids, petrol, diesel, other fuels, paint or solvents, but excluding sediment) shall be discharged to water from the activity.
  10. The owner of the structure shall inform the Waikato Regional Council in writing, at least 10 working days prior to commencing construction, of the location of the structure where that structure is located within a flood control or drainage scheme managed by the Waikato Regional Council or a territorial authority.

Advisory Notes:

  • A building consent from the relevant territorial authority may be required for a bridge under the Building Act 2004.
  • These rules do not override any requirements of drainage authorities where the activity occurs in drains administered by Waikato Regional Council or a district council.
  • Information requirements to enable the assessment of any application under Rules 4.2.8.2 and 4.2.8.3 are as set out in Section 8.1.3.1. In addition assessment shall also take into account the matters identified in Policy 2 of Section 4.2.3.
  • Construction of access tracks or causeways associated with bridges can reduce the waterway area of the river channel and floodplain. Condition c) of Rule 4.2.8.2 restricts the reduction of waterway area to no more than 10 percent of the river channel and/or floodplain.
  • Waikato Regional Council staff are able to provide information on the location and boundaries of flood control and drainage scheme areas within the Region.
  • The imposition of consent conditions relating to matters iv), v) and vi) shall take into account the policy direction provided in Policies 1 and 2 in Section 2.3.3 in addition to specific policies in this chapter of the Plan.

Explanation and Principal Reasons for Adopting Methods 4.2.8.1, 4.2.8.2 and 4.2.8.3

Bridges with single spans not exceeding 10 metres are considered to be structures that would have minor adverse effects if built in accordance with the conditions specified. Rivers over which bridges of this span pass, are unlikely to be navigable waterways. It is necessary to permit these activities to encourage use of bridges as an alternative to livestock crossing.

Bridges with spans exceeding 10 metres, that have no pier(s) in or on the bed, as provided for in Rule 4.2.8.2 are likely to require specialist design. Rivers of this size are also likely to be navigable. For these reasons these structures are controlled activities.

Bridges with spans exceeding 10 metres in length that have a pier(s) in or on the bed have the potential to have significant adverse effects and are therefore restricted discretionary activities under Rule 4.2.8.3. These structures will require specialist design and will involve works on and in the beds of rivers.
