Trail Types

The MetroGreen system will provide a full range of trail types to meet the needs of users. There are five different types of trails found within the system. MetroGreen corridors may contain more than one type of trail. The selection of a trail type is not currently defined for MetroGreen corridors and will normally be determined after further evaluation of the physical and future use characteristics for each corridor.

The five trail types are described below. More specific information is in the MetroGreen Design Guidelines, currently in Appendix D of the 2002 Plan.

No facility development

1: No facility development

For corridors that are environmentally sensitive and contain steep slopes, wetlands, or rare habitat, MetroGreen recommends a no-facility development type. It is anticipated that many corridors defined for water quality, habitat protection, and floodplain management purposes would also fit under this category. Typically, these corridors would remain in a natural undeveloped condition.

Limited development, low-impact uses

2: Limited development, low-impact uses

The second type of trail would be found within corridors that are environmentally sensitive but can also support limited trail development. These corridors would support bare earth, wood chip or boardwalk trails. Typically, uses would be limited to pedestrian only.

Multi-use unpaved trail development

3: Multi-use unpaved trail development

This designation would apply to corridors that are capable of supporting a broader range of uses. Trail development, if it occurs along a stream, would be located outside of the floodway. A variety of surface materials could be used, but crushed gravel is viewed as the most likely. These trails can be used by pedestrians, cyclists, equestrians and persons with disabilities.

Multi-use paved trail development

4: Multi-use paved trail development

Multi-use paved trails may become one of the most common types of off-road trails in the entire MetroGreen system. These trails will support the greatest diversity of users, and can be used year-round. Type 4 trails will be more expensive than other types to construct, but they will serve the needs of most users. These trails can be constructed within flood-prone landscapes as well as upland corridors.

Bike and pedestrian facilities in rights-of-way

5: Bike and pedestrian facilities in rights-of-way

These trails are generally located within the rights-of-way of roadways throughout the metropolitan area. One of the primary purposes for this trail type is to serve as a connector to the off-road network of MetroGreen. Sidewalks, bike routes, bike lanes and wide multi-purpose side paths are envisioned as the constructed facilities.
