Back at the first prototype drive-thru only Chicken Shack installing the storm drains.
All the main pipe is 18" corrugated HDPE with pre-cast 48" round inlets. There are 2 grate inlet structures (GI's) in the natural area, 4 hooded curb grate inlets (HGI's) and 1 swapping an existing HGI to a GI.
And there was a dog house manhole to tie into the main developments storm sewer system's 18" side line.
We'll pour concrete on either side of the existing RCP up to the crown and then cut a hole in the existing pipe just south of the bell.
This is where the Husky "dustless" cutoff saw will come in handy.
Backfilling an 18" pipe to an end line HGI. There will be a segmented retainer wall in front of the pipe where the proposed curb will go on top. We don't get paid to design it - just put it in..
Doghouse manhole tie in to existing top shot. The proposed retaining wall will be to the right, towards the silt fence.
One of the 2 GI's in the landscape area. There is an HGI in front of the roller for the two lane drive thru.
