This is Part 4 of a series exploring how planning decisions shape Diamond Valley’s future.
Every community conversation about growth eventually leads to a simple question:
Who pays for it?
New homes, new roads, expanded water systems—on the surface, growth can look like progress. But behind every new development is a network of infrastructure, and behind that infrastructure is a set of costs that don’t always show up right away.
Understanding those costs is key to understanding how our community grows—and what it means for taxpayers over time.
This Series: Understanding Diamond Valley’s Land Use Bylaw
This multi-part series explores how planning decisions shape growth, infrastructure, and long-term community sustainability in Diamond Valley:
Part 1: What the Land Use Bylaw Is and Why It Matters
Part 2: Growth, Infrastructure, and the Real Cost of Expansion
Part 3: Water, Environment, and Resilient Community Design
Part 4: Who Pays? Infrastructure, Development, and Long-Term Costs
Part 5: Density, Parking, and How Communities Grow
Part 6: Bringing It All Together: Planning for Diamond Valley’s Future
Understanding How Costs Are Shared
When new development occurs, there are generally three groups involved in how infrastructure costs are managed over time:
Each plays a different role.
Developers typically contribute to the cost of infrastructure required to service new developments. Municipalities are responsible for managing and maintaining infrastructure systems over the long term. Residents contribute through property taxes and utility rates that support ongoing operations and future upgrades.
These roles are interconnected, and how they balance over time is influenced by planning decisions.
The Question Behind Every Development Decision
When a new subdivision is proposed, the discussion often focuses on housing need, density, or design. But beneath those visible elements is something less obvious:
- Roads that must be built and maintained
- Water and sewer systems that must be extended
- Stormwater systems that must handle increased runoff
- Emergency and municipal services that must expand
These are not one-time costs. They are long-term commitments.
The Long-Term Reality of Infrastructure
Infrastructure systems are built to last, but they do not last forever.
Water and sewer pipes, roads, and other systems require:
- maintenance
- repair
- eventual replacement
Even when initial construction costs are covered in part by development, long-term responsibilities remain.
Over time, these costs are managed through municipal budgets, which are supported by property taxes and utility revenues.
This is why planning decisions made today can influence financial outcomes many years into the future.
What “Infrastructure Costs” Really Mean
Infrastructure isn’t just about construction—it’s about life-cycle.
A road built today:
- Requires maintenance within years
- Requires resurfacing within decades
- Eventually requires full replacement
The same applies to pipes, pumps, treatment systems, and public facilities.
Across Canada, municipalities are already facing the growing challenge of maintaining aging infrastructure—often referred to as the infrastructure deficit—a concern highlighted by the Federation of Canadian Municipalities. Federation of Canadian Municipalities.
👉 The key idea:
Growth adds infrastructure—but it also adds future obligations.
Why This Is a Planning Conversation
Planning tools such as the Land Use Bylaw (LUB) play a role in shaping how growth occurs.
By influencing where and how development takes place, these tools also influence:
- infrastructure demand
- long-term maintenance requirements
- how costs are managed over time
This is why discussions about planning, infrastructure, and cost are closely connected.
Growth Doesn’t Always Pay for Itself
There’s a common assumption that new development “pays for itself” through taxes and fees.
Sometimes it does—especially in compact, efficient developments.
But in many cases:
- Initial development fees cover only part of the cost
- Ongoing maintenance is left to the municipality
- Long-term replacement costs fall to future taxpayers
This creates a gap between what growth brings in and what it eventually costs.
A Simple Local Example
Imagine two ways a community could grow:
Option A: Expansion
- A new subdivision is built on the edge of town
- New roads, water lines, and sewer systems are extended outward
- More distance means more infrastructure per household
Option B: Infill
- New homes are added within existing neighbourhoods
- Existing roads and pipes are used more efficiently
- Less new infrastructure is required
At first glance, both options add homes and tax revenue.
But over time:
- Option A often leads to higher maintenance costs per household
- Option B tends to spread those costs across existing systems
This doesn’t mean one option is always “right”—but it highlights the trade-offs.
👉 The important takeaway:
How we grow shapes what we pay—not just today, but decades from now.
The Long-Term Cost Curve: Build Now, Pay Later
Infrastructure decisions often follow a pattern:
- Build (high upfront cost)
- Use (relatively low cost for a period)
- Maintain (costs begin to rise)
- Replace (significant cost returns)
Many communities are now entering the replacement phase for infrastructure built decades ago.
This creates pressure:
- On municipal budgets
- On long-term financial planning
- On taxpayers
A Local Lens: What This Means for Our Community
In a growing community like ours, these questions are not theoretical.
They show up in:
- Budget discussions
- Development proposals
- Long-term planning documents
They also show up in everyday conversations:
- Why are taxes increasing?
- Why are some projects prioritized over others?
- How do we balance growth with affordability?
In Alberta, municipal organizations have also raised concerns about the long-term costs of infrastructure and the pressures they place on local budgets as communities grow.
Why It Matters
Growth is not just about adding homes—it’s about shaping the future cost structure of a community.
When we understand infrastructure and long-term costs:
- We can ask better questions
- We can evaluate trade-offs more clearly
- We can participate more meaningfully in local decisions
Because in the end:
Growth is not just about what we build.
It’s about what we commit to maintaining.

I’d love to see a companion piece here explaining why there is this endless mantra that a town HAS to grow?
Why can’t it just stay as it is and be maintained through the tax revenues from the citizens – what does growth bring, beyond extra costs and infrastructure?
In my youth when at University I was very affected by Schumacher’s economic philosophy of ‘enoughness’ …
https://en.wikipedia.org/wiki/Small_Is_Beautiful
– possibly because he echoed my dear grandmother’s frequent saying, when I was even younger, that she had had .. ‘an elegant sufficiency of enoughness’ after a meal.
This world is going crazy for development and expansion. Let’s just be satisfied with maintaining what we have and living a quiet life !
This is a thoughtful perspective, and I appreciate you bringing it forward here.
The idea of “enoughness” — that a community can reach a point of balance and simply maintain what it has — is a powerful one. It’s something that doesn’t get talked about nearly enough in conversations around growth and development.
At the same time, many towns find themselves responding to pressures that come from outside the community — regional demand, infrastructure lifecycles, and how our tax and funding systems are structured.
One of the goals of this series is to make those dynamics more visible, so we can have exactly this kind of conversation as a community.
Your question — whether a town can choose stability instead of continuous growth — is an important one, and worth exploring more fully. I’ll plan to follow up with a companion piece on that topic.
Thanks Ken, for adding this here — it’s a valuable part of the discussion.
