  • Choosing Between Concrete Asphalt

    Concrete and asphalt both have their benefits and when choosing between the two, it often comes down to personal preference and what fits within your budget. For this reason, we offer both and are willing to help you determine which is right for the specific needs of your business or space. Concrete has the ability to be enhanced in unique ways that asphalt cannot. It also has an extensive life with proper upkeep and care.

  • ADA Accessible Parking

    We specialize in providing restriping and accessible parking spaces as required by the ADA Standards for Accessible Design. We are skilled in various aspects of ADA Design, including the minimum number of accessible parking spaces, distance route from accessible entrance, removing barriers to proper access, and properly sized parking spaces for cars and van-accessible spaces.

At Larsco Construction, we understand that a well-designed parking lot does more than provide vehicle storage it shapes the first impression of your property, directs safe traffic flow, and ensures accessibility. Whether you’re working with a small business lot or managing a large commercial complex, our team specializes in strategic parking lot expansion and professional layout design tailored to your property’s function, compliance, and long-term value.


Upgrading or expanding a lot is not just about adding pavement. It’s about smart planning ensuring your layout supports customer volume, meets ADA and local code requirements, and reduces long-term maintenance risks. We help property managers, facility directors, and business owners rethink their lot design to increase capacity, improve flow, and deliver a more professional exterior presence.

Why Parking Lot Expansion Matters

Over time, your parking needs change. Businesses grow, visitor volume increases, and original layouts no longer serve your daily operations efficiently. In other cases, your lot may have simply been undersized or poorly designed from the start.


Cramped lanes, awkward angles, and lack of proper traffic markings all lead to frustration and potential safety hazards. Our team addresses these issues with thoughtful design that considers everything from turning radiuses to drainage and pedestrian access.



Expanding your parking lot may involve extending into unused land, connecting to new access points, or re-striping to increase vehicle capacity. Whether you’re planning ahead for future traffic or responding to immediate congestion, we work with you to design a layout that fits.

How We Approach Layout Design

Every parking lot design starts with understanding your property’s footprint, usage, and goals. Are you operating a retail plaza that sees heavy weekend traffic? A medical facility with patient drop-off needs? An industrial site with large vehicle loading zones? We account for all these use-case factors in the planning process.


After an on-site assessment, we take into account existing pavement conditions, drainage behavior, utility access, and land grading. Our designs aren’t just compliant they’re customized to serve how your space functions every day. This results in improved traffic patterns, better visibility, and a smoother experience for your customers, employees, or tenants.



We also ensure the expansion ties seamlessly into your existing pavement. That means matching elevation, surface thickness, and asphalt type to create a uniform, strong structure. Proper base preparation ensures longevity, and clean transitions prevent premature cracking or settling.

Key Elements of a Good Parking Lot Design

A functional parking lot layout is about more than striping rows. It balances safety, efficiency, and durability. We focus on the following core elements when designing or expanding your parking lot:


  • Traffic Flow: Clear directional pathways, appropriate turning radiuses, and safe exit/entry points.
  • Vehicle Capacity: Maximizing space without overcrowding or compromising ADA accessibility.
  • Drainage Control: Grading and water movement to avoid standing water or pavement damage.
  • Pedestrian Access: Defined walkways, ramps, and safe crossings that keep foot traffic out of harm’s way.
  • Lighting & Visibility: Layouts that account for lighting placement and nighttime navigation.
  • Material Consistency: Matching surface thickness and composition to prevent premature failure.


These principles guide both new construction and retrofits to ensure long-term success.

Planning for ADA Compliance

ADA standards are a critical part of modern parking lot design. They govern everything from the number and location of accessible spaces to the slope and width of aisles and access routes.


During layout planning or expansion, we ensure all compliance factors are addressed. That includes van-accessible spaces, clear signage, proper striping, and barrier-free travel paths from parking to your building entrance.


Failure to meet ADA standards doesn’t just put your visitors at risk it can also lead to costly fines or accessibility complaints. Our team designs with compliance from the start, so you can rest assured your lot is safe and legally sound.

Asphalt Expansion Process

When expanding your asphalt lot, we follow a structured process to ensure quality and longevity:

  • 1. Site Preparation

    We clear the expansion area of debris, topsoil, and organic material. The subgrade is excavated and compacted to create a stable base. If utility adjustments are needed (e.g. drainage or lighting), this is the stage where we coordinate them.

  • 2. Base Installation

    A graded, compacted base layer of crushed aggregate is added to support the asphalt surface. This layer is crucial for drainage and structural strength.

  • 3. Matching the Existing Lot

    We match the new asphalt thickness and finish to your existing surface. Joints are saw-cut and treated to bind new pavement to old, preventing cracks where the two surfaces meet.

  • 4. Asphalt Paving & Compaction

    High-quality hot-mix asphalt is laid, leveled, and compacted. We ensure a consistent surface with proper slope to direct water away from buildings and low points.

  • 5. Curing & Striping

    Once cooled and cured, the new area is striped using traffic-grade paint to match or complement your overall lot layout. New striping may be extended across the old surface if you're redesigning capacity.

Common Reasons to Expand a Parking Lot

Each expansion is different, but common scenarios include:


  • Business growth leading to increased customer or employee traffic
  • Tenant complaints or parking shortages
  • Preparing for special events or high-season volume
  • Converting unused land into functional vehicle space
  • Replacing inefficient layouts with better angled parking and traffic control
  • Preparing for inspections or accessibility audits


If you're not sure whether you need an expansion, we’re happy to evaluate your current layout and make honest recommendations based on space, safety, and return on investment.

Choosing the Right Layout

A smart parking lot layout balances vehicle capacity with safety and comfort. Angled stalls (30°, 45°, or 60°) offer easier entry and exit in tighter lots. Straight (90°) stalls maximize quantity but require more space for turning lanes. We help you find the right approach depending on your lot size and traffic volume.



One-way vs. two-way traffic flow is another major consideration. One-way designs often allow for more stalls, but require proper signage to prevent confusion. We’ll walk you through the tradeoffs and help design a lot that meets your goals.

Long-Term Durability and Maintenance

Expansion isn't just about adding surface area it’s about making your entire lot more durable. We use quality materials, proper grading, and strong compaction techniques to prevent early wear.


We also offer ongoing maintenance services such as crack sealing, line restriping, and sealcoating. Even the best-designed lot will eventually need attention, and we’re here to make sure your investment lasts as long as possible.

FAQ: Parking Lot Expansion & Layout Design

  • How many parking spaces do I need?

    The number of spaces depends on your property type and local zoning codes. We can help you determine this based on square footage and use.

  • Can I expand onto a grassy or undeveloped area?

    Yes, as long as the soil is stable and permitted by local code. We'll evaluate and grade the land for proper drainage and support.

  • Do I need a permit to expand a parking lot?

    Most expansions do require permitting, especially for commercial or multifamily properties. We assist with the permit process and ensure all work is compliant.

  • How long does expansion take?

    Typical expansion projects take 3–7 days depending on size, weather, and access. Larger or phased projects may take longer.

  • Will the new section match my existing pavement?

    Yes. We match material type, thickness, and finish to provide a seamless surface with no visible transitions.

  • Can I update my striping at the same time?

    Absolutely. We recommend restriping the entire lot when expanding to ensure a uniform look and correct spacing.

  • Do you offer design consultations?

    Yes. We’ll walk the site with you, evaluate traffic flow, and propose layout improvements that meet your goals and budget.
