This particular day of construction at the 84 Lumber site in Newbury shows a lot of the stormwater system we have talked so much about here in the Newbury blog.
In this photo, you can see an endwall where stormwater discharges into Millers Run. The rocks scattered near the bottom are known as a “rock apron”, and they slow the stormwater down to avoid erosion of the stream bank.
In the center of the following photo you can see the manhole that contains a pipe that water will flow through to reach the endwall.
Below, is a compactor. It moves by remote control, and vibrates as it rolls, to provide compaction for the “pipe bedding”. The endwall pictured below is waiting for its rock apron.
Two photos showing a worker using a remote to work the compactor and dirt being moved to have fill cover the pipe bedding.
Next, you can see both end walls have been completed. The rock apron has been installed on both!
This panorama shows the progress that has been made at the 84 Lumber site. Here it is in high resolution.
The next three photos show fill coming in to the 84 Lumber site. An additional ten inches of fill still needs to be placed on the 84 Lumber site to bring it up to final grade. Keep checking the blog to see this transformation over the next few weeks!
This photo shows more of the stormwater system. The manhole is connected to a pipe that is connected to the discharge point of the chamber. Stormwater will flow from the chamber through these pipes to the endwalls pictured at the beginning of this construction udpate.
The inside is formed with concrete to create a “water-tight” connection between the pipe and the manhole.
