Rogers Road Washout

Here are some pictures of the 10/8/16 Rogers Road washout caused by Hurricane Matthew, as well as pictures of the repair work. Toward the end they worked seven days a week to repair the damage.

The culvert replacement is much more elaborate than I had expected. They had to temporarily divert the creek using a large pipe, for which I guess they had to tunnel under the road. For a while they had what looked like a coffer dam around the work area. By mid November they had removed the old culvert and dug a wide, deep trench to hold the new, bigger culvert. In late November they laid the new culvert, including some large side pieces, not present on the old, much smaller culvert. But by the next day they had temporarily removed the side pieces and the main work seemed to stop. (Were the pieces sent back for repair?) The side pieces reappeared after a few days. Then work resumed to cover the pipe with fill, pack it down, put in raprap on the stream bed and sides, pave the road, stripe it, and lay down some straw covering on the roadsides. As of 12/11/16 there was still some utility work to be done; e.g., some large cables were lying near the road and across the creek. Shortly before 2/20/17, the remaining cables were either cut off or buried and the portable bathroom was removed.

On 12/5/16 Rogers Road reopened for traffic. And the litterers have definitely returned.

The washout stream {Basin 6, Stream 8} under Rogers Road is called Reedy Creek on the Flood Risk Information System (FRIS) maps. However other maps (e.g., Google Maps and iMaps) already call it Sanford Creek when it goes under Rogers Road, although that is probably a premature name. To the east, near where the Sanford Creek trailway exits at Rogers Road, there is a larger, but unnamed creek; FRIS designates it as {Basin 6, Stream 9}. That creek goes under Rogers Road using two, large, side-by-side culverts, which seemed to handle Hurricane Matthew with no damage to the road. Per FRIS, Sanford Creek by name doesn't begin until {Basin 6, Stream 8} and {Basin 6, Stream 9} merge just south of Sanford Creek Ave. into {Basin 6, Stream 7}. that is over half a mile west of Rogers Road. In addition there are also other streams merging from the south to eventually create Sanford Creek. See diagram. All in all, it's a complicated system, including old "canals" (manmade?) between some of the streams.

I submitted a question to FRIS about a possible mislabeling in their map of {Basin 6, Stream 8} under Rogers Road, which they call "Reedy Creek" instead of "Sanford Creek". This is before the downstream merge with the unlabeled {Basin 6, Stream 9}; after that merge there is no question the stream should be labeled "Sanford Creek" as it is in the FRIS map. Note there is another creek in west Raleigh labeled "Reedy Creek" in the FRIS map. It is near Reedy Creek Elementary School and Reedy Creek Lake, so the map's label of "Reedy Creek" for that western stream seems pretty solid. I haven't gotten a response from FRIS so far.
