Boardwalk Height
Boardwalk height is a function of terrain type and can ramp
up gradually (3% grade) to transition from one habitat type to another.
Crystal River
Churchhouse Hammock Boardwalk is low with a “Kick Rail”.
Wetland and open
water are best viewed from a walkway height as close to the high water level as
possible. Low (18”) level boardwalks typically have a wooden curbing called a
kick rail along the sides to assist mobility or eye sight impaired hikers.
Sawgrass Lake
Park Boardwalk transition from kick rail curbing to handrail.
The low kick rail
also improves visibility at low angles for viewing objects close to the walkway
or under water. Fast water or deep streams may require a hand railing and slats
for safety purposes. Foundations for this type of boardwalk are typically
straight posts or pilings and 90 degree cross beam supports.
Intermediate height walkways up to 48” should have a hand
rail. Foundations are thicker posts or pilings, and have “X” cross bracing in
the cross trail direction. As the walkway turns or transitions in height,
additional bracing, cable guys, or angled piers may be needed.
Weedon Island
Preserve Boardwalk transition to observation tower, with respite sections
between inclines.
As boardwalks
transition upward, some of them up to 12 feet in height to avoid steps or
stairs, they alternate between an incline and level sections. This not only
aids in stability and structural soundness, it allows respite areas for
mobility impaired trail users.
Boca Ciega
Millennium Park Boardwalk through the salt flats and over a surface hiking
trail.
Tall boardwalks that are not piers or bridges over open
water are rare, and can be used to connect to a viewing tower or to avoid
building a tower. Tall boardwalks are braced in both cross trail and linear
trail directions, and have multiple pier, angled pilings, or cable guys. Wind
and hiker live loads can be a factor in the perceived stability of these
structures.
