When we purchased this property, this was a soybean field… Property jad many high and low points. The railroad would be going over a few waterways from rain/storms. One of the first retaining walls built was the Bluefield Town retaining wall… As we progresses, the next wall built was the Sparta retaining wall… Roughyly, there was 16 feet between these 2 walls… I built a “Y” shaped bridge to traverse the waterway.
The 16 foot separation of the walls was not wide enough to allow the flow of water from severe rainfalls, like 2 inches of rain in a few hours… The dirt was being washed out, and I was afraid the retaining walls would eventually be undermined… Hence, the construction of a sunken waterway under the “Y” bridge to allow the water to flow without creating damage.
Below is a picture of the spillway that was built.
The weekend before the Oct Ops session, we had rain for almost a week… During this week, we had one storm that lasted about 25-30 minutes, and dumped almost an inch of rain. During this rain, Jane went out and took pictures of the waterway in action…
From these pictures, our next course of action was decided.
-
Make the spillway lip all the same height… When we built this, we built the spillway lip ro rhe surrounding ground levels… However, from the pictures, it shows that this only hinders the water spilling into the spillway…
-
Build a higher berm along the Sparta retaining wall, to direct the flow of water out and over to the spillway lip…
Below are some pictures of the other waterways that we have created:
