The Importance of Site Selection & Infrastructure Planning

The success of a multifamily development starts long before the first foundation is poured. Choosing the right site and ensuring it has the necessary infrastructure is critical to the project’s long-term viability. Factors such as utility access, soil conditions, flood risks, and traffic flow can greatly impact construction feasibility, timelines, and costs.

At KennMar Construction, we recognize that a poor site choice—or one with significant infrastructure challenges—can lead to delays, unexpected expenses, and operational inefficiencies. Our approach to site selection and infrastructure planning ensures that multifamily developments are positioned for long-term success.

1. Evaluating Utility Availability & Capacity

One of the first steps in site selection is ensuring that essential utilities—water, sewer, gas, and electricity—are available and sufficient to support the planned development.

Potential Challenges:

  • Some sites may lack the necessary sewer or water capacity, requiring expensive system extensions or upgrades.
  • Natural gas and electricity providers may not have existing lines close to the site, requiring additional infrastructure investment.
  • Aging or overloaded infrastructure may need updates to meet modern multifamily development needs.

KennMar Construction’s Approach:

To mitigate these challenges, KennMar Construction conducts comprehensive utility assessments early in the development process. This includes:

  • Coordinating with local utility providers to assess current capacity and potential extension costs.
  • Evaluating alternative solutions, such as on-site water storage or booster pumps for water pressure concerns.
  • Incorporating energy-efficient systems to reduce long-term infrastructure demands and operational costs.

By addressing utility concerns upfront, we help developers avoid costly last-minute changes and infrastructure delays.

2. Assessing Soil Conditions, Flood Zones & Topography

The condition of the land itself can significantly impact construction feasibility and costs. Poor soil conditions, flood risks, or challenging topography may require additional site preparation, foundation reinforcements, or drainage solutions.

Potential Challenges:

  • Unstable or poor soil conditions (e.g., expansive clay, loose sand) may require specialized foundation systems.
  • Sites located in flood zones may necessitate elevation adjustments, stormwater management, or additional permitting.
  • Uneven topography may require extensive grading and earthwork, increasing project costs.

KennMar Construction’s Approach:

Our geotechnical due diligence process ensures that no surprises arise once construction begins. We:

  • Conduct soil borings and geotechnical testing to determine if soil stabilization or specialized foundations are needed.
  • Assess floodplain mapping and stormwater regulations to proactively design drainage solutions.
  • Evaluate grading requirements and foundation design options to balance cost and feasibility.

This proactive approach prevents costly delays and ensures that the site can structurally and environmentally support the development.

3. Planning for Traffic Flow, Road Access & Pedestrian Connectivity

A well-planned multifamily development must integrate seamlessly with surrounding road networks, public transportation, and pedestrian pathways.

Potential Challenges:

  • Inadequate road access can create congestion and safety concerns for residents and the surrounding community.
  • Limited public transportation options may impact leasing potential and accessibility.
  • Poor pedestrian connectivity can reduce walkability and limit access to nearby amenities.

KennMar Construction’s Approach:

We collaborate with traffic engineers and urban planners to design developments that prioritize both vehicle and pedestrian accessibility. Our approach includes:

  • Traffic impact studies to identify potential congestion points and required road improvements.
  • Optimized site layouts that allow for efficient ingress/egress, minimizing bottlenecks.
  • Walkability enhancements such as sidewalks, crosswalks, and bike lanes to improve pedestrian access.

By planning for multi-modal transportation access, we help developers create communities that are both functional and desirable for residents.

The KennMar Advantage

Choosing the right site for a multifamily development requires more than just location—it requires a deep understanding of infrastructure, environmental constraints, and long-term livability.

At KennMar Construction, our proactive site selection and infrastructure planning ensure that projects are built on solid ground—literally and figuratively. From utility planning and geotechnical assessments to traffic flow optimization, we help developers navigate challenges before they become costly setbacks.
