Bridging A panel installed above overgrown tree roots connecting other sections of sidewalk surrounding overgrown roots, creating a slight rise in the sidewalk. Provides grade separation between tree root zone and sidewalk, allows tree roots to grow in soil, potential materials include concrete or steel panels, may be used to preserve a high value tree. Site-specific requirements determine if this resolution is feasible, a nonslip surface treatment is required for metal/ steel materials, additional ADA requirements apply. Still slippery with non-skid plates. Curving or Offset Sidewalk Modify sidewalk path to accommodate for tree preservation. Gives trees more growth space, increases pedestrian safety by separating sidewalks from vehicular traffic. Requires adequate space in the right- of-way, requires coordination with private property owners, care must be taken to ensure ADA compliance. Curb Extensions (bulb outs) Extends the sidewalk a short distance, often at an intersection, providing additional pedestrian space and narrowing roadways. Increases pedestrian safety through traffic calming and shortening crossing distances. Impacts to drainage and existing utilities, site specific transportation conditions or impacts. High maintenance costs due to landscape and irrigation. Easement/ Suspended Pavement Systems Pavement supported by and lifted over a void space filled with soil for root growth. Creates a viable tree site where previously not possible. Involves removing and repaving sidewalks, considerations for site-specific grading requirements. Requires coordination with the resident.
