Summit Creek Viaduct
The extensive pedestrian viaduct planned near Summit Creek will present specific challenges
to revegetation efforts. The viaduct will cover approximately 0.16 acres and will prevent
precipitation and direct sunlight from reaching the surface of the ground below the viaduct
deck. Currently there are micro-habitats that have a variety of vegetation growing at the toe
slope of rock walls. Soil accumulates at the junction of the rock wall and ground, and
precipitation drips down the face of the rock; both contribute to the ability to support plant
life. Revegetation efforts will take advantage of similar micro-habitats under the viaduct,
utilize shade tolerant plant species, and incorporate organic matter into the soil to aid in
