Introduction

This guide explains how Wellington City manages requests, design criteria and enforcement for roundabouts and speed bumps across Wellington, Wellington Region. It summarises the controlling instruments, the departments responsible, typical application steps and what residents should expect when proposing traffic calming or intersection changes. Use this as a practical checklist to apply, report issues or appeal decisions under Wellington city traffic controls and bylaws.

Consult the council early when you see a recurring safety issue.

How installations are assessed

Wellington City assesses traffic calming and intersection changes on safety, traffic volume, vehicle speeds, pedestrian desire lines, property access, public transport routes and emergency vehicle requirements. The council uses engineering standards and local policies to prioritise schemes and to decide between roundabouts, speed cushions, raised crossings or other measures. For general transport policy and program information, see the Transport pages on the Wellington City website [1].

  • Safety data analysis including crash history and near misses.
  • Traffic counts and peak hour flow assessments.
  • Impact on buses, emergency services and cyclists.
  • Engineering feasibility and drainage or utility conflicts.
Not every speed or volume concern will meet the formal criteria for physical calming.

Design standards and approvals

Designs must meet recognised engineering standards and local specifications adopted by the council. Proposals typically progress from request to preliminary assessment, community consultation where required, design and then construction. Council contractors or approved suppliers usually deliver physical works under council supervision. If a formal bylaw or specific technical standard governs the device location, that instrument will be referenced during assessment [1].

Penalties & Enforcement

Enforcement of rules about unauthorised road alterations, illegally installed traffic calming devices or removal of council-installed traffic controls is carried out by Wellington City Council officers and authorised contractors. Complaints and enforcement requests can be made via the council report service [2]. Where works or installations affect the public road, the council may require removal and restoration at the property owner's expense.

  • Monetary fines: not specified on the cited page [1].
  • Escalation for repeat or continuing offences: not specified on the cited page [1].
  • Removal orders and restoration works at the offender's cost.
  • Court action where specified offences or non-compliance persist.
  • Enforcer: Wellington City Council Transport and Traffic Operations; complaints via the council report service [2].
If you are unsure whether a change needs council approval, contact the council before acting.

Applications & Forms

Applications or requests commonly start with an online request or service report to council; the council may require a formal application or a traffic resolution for permanent changes. Specific application form names, numbers, fees and deadlines are not specified on the cited page [1]. Contact the council report service to begin a request or to ask which forms apply [2].

Typical process and action steps

  • Step 1: Lodge a service request or traffic-calming proposal with council via the online report form [2].
  • Step 2: Council performs data collection and site assessment.
  • Step 3: If required, council runs community consultation or seeks stakeholder input.
  • Step 4: Design, procurement and construction if approved.
Community support does not guarantee installation but can influence prioritisation.

FAQ

Who decides if a roundabout or speed bump is installed?
The council's Transport and Traffic Operations team assesses requests and makes decisions based on safety, traffic data and network impacts.
Can a resident install a private speed bump?
No. Alterations to the public road require council approval and unauthorised installations may be removed and charged to the owner.
How long does an assessment take?
Assessment times vary by workload and complexity; the council does not publish a fixed statutory timeframe on the referenced pages.

How-To

How to request traffic calming such as a roundabout or speed bump:

  1. Report the issue online via the council service request page to register the concern and provide location details [2].
  2. Provide any supporting evidence such as photos, witness accounts, or local data about speeds and near-misses.
  3. Agree to any site assessments or community engagement arranged by the council.
  4. If approved, follow council guidance for any property impacts and timelines for construction.

Key Takeaways

  • Wellington assesses calming based on safety, traffic and network impacts.
