Where the trail will be placed alongside a roadway, special considerations must be made to promote a safe and comfortable experience for trail users.
This cross section should be used where trail is to run parallel to roadway.- The design of this cross section focuses on promoting a high level of safety and comfort for trail users along roadways.
- Trail grading to slope towards roadway where feasible.
- Buffer elements, such as tree and vertical plantings, are highly desirable to separate trail and roadway. See Trail Shoulder Standards for standard treatments based on available shoulder widths.
- Sheetflow of runoff to roadway gutter/stormwater system may be acceptable where road commission agrees. Otherwise, designers should provide a permanent stormwater BMP in buffer if feasible where right-of-way allows.
- Where there is significant demand for pedestrian access across buffer, consider paved connections between trail and roadway. BMP design should always provide accommodations for pedestrian connections (See Trail with BMP).
- Strip existing topsoil for reuse in finished grading.
- Along roadway, tree soil volume needs may require use of structural cells or structural soil. Root barrier may also be required. See Trees.
