Designing Smarter: How Municipalities + Developers Can Partner to Mitigate Infrastructure Costs

Infrastructure costs represent a significant portion of any land development budget. Managing these costs effectively requires careful planning and strong collaboration.

The most successful developments start with strong partnerships, specifically between a municipality, developer, and design team. While other firms may talk about coordination, ISG has an effective and impactful approach for this three-way partnership. By aligning goals early and integrating design strategies from the start, we consistently help clients manage infrastructure costs and deliver lasting value.

The Three-Way Partnership That Drives Better Outcomes

Municipalities aim for growth that is resilient, connected, and aligned with long-term plans. Developers focus on delivering projects that meet market demand and stay financially viable. Designers bridge the gap—translating community goals and developer priorities into solutions that work for both. When these goals are addressed together, smarter decisions and more efficient infrastructure investments follow that benefit both the community and the developer.

Here is how we help drive those outcomes:

1. Strategic Design to Control Costs + Enhance Value

From ISG’s perspective, infrastructure decisions are not just technical—they are strategic. Thoughtful design has the power to control costs, enhance community value, and prevent long-term inefficiencies.

In Lino Lakes, Minnesota, we supported the planning of a 117-acre mixed-use site that included senior housing, market-rate apartments, affordable housing, commercial space, and single-family lots. Working with developers before a design partner was formally selected, our team helped model lot sizes, street layouts, and density options that met market demand while supporting livability and municipal standards.

We also focused on connecting the site to surrounding roads, parks, and utilities. Without those connections, we have found that infrastructure becomes isolated, is costly to maintain, and feels disconnected from the broader community. Strategic design solves that.

2. Planning To Align Vision + Reality

Municipal zoning codes play a vital role in shaping land use and guiding community growth. However, those codes can sometimes limit a developer’s ability to respond to real-time market needs. For example, zoning may restrict certain housing types or prescribe lot sizes that do not align with what buyers are currently seeking or what is financially feasible for the developer.

Early collaboration allows municipalities and developers to align community goals with real-world conditions. Designers serve as translators—interpreting codes, identifying areas of flexibility, and finding solutions that work for both sides.

Key planning decisions that influence infrastructure costs include:

• Lot sizes that balance affordability, density, and infrastructure efficiency
• Street layouts that optimize circulation without overbuilding
• Connectivity that supports community integration and scalable infrastructure
• Phasing plans that encourage an incremental approach and minimize upfront costs while supporting long-term growth

3. Balancing Market + Infrastructure Needs

Design partners can help municipalities and developers evaluate trade-offs for land use and design decisions early. This helps balance market demand, infrastructure performance, and cost realities.

An example of how housing types drive infrastructure needs and costs include:

• Single-family developments typically require more land area and longer runs of roads, water, sewer, and other utilities. This spreads infrastructure over a wider footprint, which can increase initial construction and ongoing maintenance costs. The lot size also sets the maximum land value a municipality can benefit from financially and the product type and price point a developer is evaluating as part of their pro-forma.
• ‍Multi-family developments concentrate more units within a smaller area, reducing the overall land needed and shortening some infrastructure runs. However, they have different infrastructure demands, such as the need for additional capacity for water and sewer, as well as more complex systems for stormwater management. The use of less land can allow for multiple product types and other uses utilizing the same infrastructure.

4. Creating Cost Efficiency Through Collaboration

Infrastructure decisions made in silos often lead to rework and higher costs. When developers, municipalities, and designers collaborate early, the results are smarter, more efficient outcomes.

Early collaboration enables:

• Site layouts that reduce utility runs and right-size street networks
• Phasing strategies that match infrastructure buildout to real market absorption
• Shared investment in infrastructure that supports adjacent or future growth
• Fewer redesigns, saving time and money for everyone

Take Action: Start the Conversation Early

Effective infrastructure planning starts with asking the right questions—and bringing the right people into the conversation early that are willing to engage and participate. If you are a municipality or developer looking to navigate infrastructure complexities with confidence, engage with ISG professionals who bring proven processes and experience to the table.
