The following is a summary of the improvements proposed on South Gate, North Gate, and Summit Roads: -Install new or repair/replace failing existing drainage collection points; repair, modify, or replace existing road culverts or install new culverts where needed; install rock slope protection on the cut side of the roadway to limit erosion; repair existing retaining walls; restore existing road embankment in areas of severe subsidence. -Reconstruct or stabilize approximately 500 linear feet of road base structural sections with reinforcing geotextile fabric; install a subdrainage system to divert water away from the road section prism on North and South Gate Roads. Replace existing road surface on Summit Road.
