Maximizing Your Dock Widths: Understanding Width Restrictions and Design Tips

When planning a dock walkway, knowing the rules and regulations is crucial to avoid complications. Let’s delve into the specifics of walkway width restrictions and offer some tips for optimizing your dock design.

Walkway Width Restrictions

The maximum width for a dock walkway is universally restricted to four feet. This rule is enforced by the city, the Department of Environmental Protection (DEP), and the Army Corps of Engineers. The four-foot width is non-negotiable and applies to the entire length of the walkway leading out to the terminal platform where you park your boat.

Terminal Platform Size Limits

Your terminal platform’s size is dependent on the type of decking you choose:

1. Grated Decking:

  • Maximum Size: 160 square feet
  • Requirements: Must use a grated material allowing at least 43% of light to pass through (known as LTM or light transmittance material).

2. Solid Decking:

  • Maximum Size: 120 square feet
  • Requirements: Solid decking does not meet the light transmittance requirement, limiting its size.

Design Configurations

You can arrange your terminal platform in various ways, provided it doesn’t exceed eight feet in one direction. Standard configurations include:

  • 8 by 20 feet
  • 5 by 33 feet

However, these dimensions can vary as long as they adhere to the maximum square footage and directional limits.

Tips for Optimizing Walkway Width

One challenge with the four-foot width restriction is ensuring adequate clearance between posts. Here’s a strategy to maximize your walkway space:

Post Placement: Instead of centering your posts along the deck line, place them on the outer edges of the deck. This approach provides a full four-foot-wide path between the posts.

Advantages:

  • Maximized Walkway Width: Ensures you utilize the entire four feet without obstructions.

Disadvantages:

  • Installation Complexity: Aligning posts perfectly straight on the outer edges is challenging due to varying post diameters (ranging from 10 to 14 inches). This can cause the deck edge to appear uneven.

Aesthetic Consideration:

  • Centered Posts: While placing posts in the center reduces the clear walkway width to about three feet, it breaks up the deck edge visually. This method prevents noticeable alignment issues, maintaining a cleaner aesthetic.

Conclusion

When designing your dock, adhering to these width and size regulations ensures compliance and functionality. By strategically placing posts and choosing the right decking materials, you can create a practical and visually appealing dock walkway that meets all regulatory standards. Whether you prioritize maximum walkway clearance or aesthetic appeal, understanding these guidelines will help you make informed decisions for your dock project.
