OVERALL PLAN

LSC Loop Trail 15% Concept Design | 5

• Trail is positioned on the inside of the LSC Loop

• Typical trail cross section includes a paved shared use path with planted buffers on each side

• Enhanced street crossings are recommended for all intersections

• Potential trail spurs should connect to routes and destinations beyond the LSC Loop Trail

• Enhancements along the Loop Trail include a distinctive paving treatment; a continuous line of street trees (preserved or planted in all possible locations); seating areas along the trail; signage/wayfinding elements; and public art in select locations

• Urban/activity areas should incorporate special paving and furnishings, larger gathering areas, enhanced plantings, and public art elements

• Gateways can use art pieces and informational signage to emphasize entry into new areas and direct users to their destinations

DESIGN ELEMENTS

• The following section provides an overall design language for both common design elements and areas with special treatments. The recommended design elements constitute a suggested style language to guide subsequent phases of design, rather than specific design specifications.

• Design elements most appropriate for Urban/Activity Areas (UA), Open Space/Natural Area (ON), and Gateways (G) are labeled as such, per the legend; however, if desired, these design treatments may be applied to other segments of the trail, as feasible.

1 Paving band at trail edges should be uniform in material, color, and dimensions along the entire length of the loop trail.

2 Paving field may be comprised of unit pavers or asphalt. Unit pavers should be used in urban/activity areas.

3 Dividing line at center of loop trail can be marked with unit pavers in paver field and painted striping in asphalt areas.

4 Permeable pavers or crushed stone should be used in amenity areas along the trail.

Special pavement markings should be used at merge zones and intersection approaches to alert users of potential conflict points.

• Tree panels should be planted with shade trees and turf grass. Shrubs and perennial plantings can be considered to enhance amenity areas, particularly within urban zones.

• When planted, the 2’ buffer should contain mown turf only, so as to not impede travel along the trail and for use as a pull-off shoulder.

• Plantings can vary within additional amenity spaces along the Loop Trail (within or outside of the right-of-way). Shrubs, perennial plantings, and additional shade trees can be considered to enhance amenity areas, particularly within urban zones. Where parking lots or secondary roadways are adjacent to the trail, wider planted buffers should be used.

A LOOP CONTINUATION PER MASTER PLAN

< 5% SLOPE WITH SWITCHBACKS≈ 6.5% SLOPE

• Missing roadway connection per GSSC Master Plan between Belward Campus Drive and Great Seneca Highway/Decoverly Drive leaves a gap in the Loop Trail

• If roadway is constructed per Master Plan recommendation, the Loop Trail should be incorporated according to the 15% Concept Design typical alignment and cross section

• Options A and B, below, provide alternatives to continue the trail which do not require construction of this roadway

*Crossing of Great Seneca Highway may be (1) two-stage unsignalized crossing utilizing existing median or (2) signalized with continuous crosswalk (if area-wide development necessitates a signal at this intersection). To be determined in consultation with SHA.

PROS:

• Achieves Master Plan loop trail alignment

• Provides direct connection between Belward Campus Drive and Decoverly Drive

CONS:

• Requires significant regrading and removal of existing vegetation

• May require encroachment into forest conservation easement

• No existing crossing at Great Seneca Highway (would need to be coordinated with SHA)*

PROS:

• Does not require significant regrading and removal of existing vegetation

• Does not require new crossing at Great Seneca Highway

CONS:

• Creates “dead end” at Belward Campus Drive

• Does not achieve Master Plan loop trail alignment

• Existing sidewalks may not be sufficient to support shared use
