Budgéter les development contributions pour une territorial authority

Restate the scheme in the units the council's policy counts in, usually household equivalent units or an equivalent measure per activity, split by the activities the policy charges for: water, wastewater, stormwater, transport, reserves and community infrastructure. Record the demand the site already carries, because a redevelopment is charged on the increase rather than on the whole.

Pourquoi: The assessment is arithmetic once the units are agreed, so the units are the whole argument. A scheme described in the developer's language and assessed in the council's is a scheme whose figure nobody can reproduce, and the credit for existing demand is the single most commonly missed line, worth more than most of the details anybody spends time on.

Price the contribution into the early estimate as its own line, activity by activity, and read what it does to the residual land value. Do it at the point the scheme is still being sized, because the number moves with unit count and with the mix of activities rather than with the build cost.

Pourquoi: On a medium density scheme the contribution can be a substantial share of the total development cost and it lands before any revenue does. Discovered after the land is bought it comes straight off the margin, because the only remaining lever is the number of units, and that is the lever that changes the contribution too.

Hold the contribution risk as a named allowance rather than inside a general contingency: the policy is reviewed on a cycle with the long-term plan, the rates move with it, and a project consented after a review is assessed on the rates in force at the time. Record what would release the allowance, which is usually the consent being lodged and assessed.

Pourquoi: A long-dated scheme can cross a policy review between feasibility and consent, and the movement is a policy decision rather than market drift, so no cost index will predict it. Held as a named allowance it can be released deliberately when the assessment arrives; buried in contingency it is spent on something else long before the invoice comes.

When the notice of assessment arrives, read it line by line against the calculation you made in the feasibility and settle a position: accept it, object to it inside the window the Act gives, or open a development agreement in which the works or the payment are agreed with the council instead. Keep the notice, the working and the reply together on the record.

Pourquoi: An objection is heard by independent development contribution commissioners rather than by the council that made the assessment, which makes it a genuine route and not a complaint. It is also a route with a deadline, and it is argued on the grounds the Act allows, such as the assessment misdescribing the development or the policy having been applied incorrectly, so the work done at the scoping step is the evidence for it.

Place the contribution in the cost plan as its own line under development costs rather than inside the infrastructure or external works packages, split by the activities the policy charges for. Keep it comparable across schemes so the cost per unit can be read from one project to the next.

Pourquoi: A contribution folded into external works distorts every rate benchmark the business keeps, and it does so silently, because the total still looks right. It also hides the one comparison that is genuinely useful to a developer, which is what different councils charge for the same building, and that comparison is a location decision rather than a design one.

Report the contributions across the portfolio with the event that makes each one payable, which under the policy may be the resource consent, the building consent, the service connection or the certificate that lets a subdivision proceed, and with what the council may withhold until it is paid.

Pourquoi: This is the step that turns a known cost into a programme risk. A council entitled to withhold a code compliance certificate or a water connection until the contribution is paid can stop a settlement date, and the money is usually wanted at exactly the point in a development when there is least of it. Read a quarter ahead it is a drawdown. Read on the day it is a delay.
