Raleigh Water Sewer Maintenance staff discovered an area of
streambank erosion under a foot bridge on the Crabtree Creek
Greenway trail near 4424 Oak Park Rd. (Lat. 35.842083, Long. -

cross an unnamed tributary that flows to Crabtree Creek.
Approximately 120 linear feet of streambank will be stabilized, 60
linear feet on the east side of the stream and 60 linear feet on the
west side of the stream. The repair area is located within a 30-foot
wide sanitary sewer easement. The sewer maintenance staff can
access the site area by Crabtree Creek Greenway Trail Entrance
(near 4300 Oak Park Rd.).
The following activities are proposed at this location:
• Erosion control measures and a dry work area will be established
prior to work beginning.
• The eroded area around and under the bridge will be filled with
appropriate backfill material.
• The streambank will be stabilized with rock/geotextiles.
• All disturbed areas will be seeded and mulched upon completion of
work.
