Pictures from this week at the auto parts store.
The front parking spaces will be pervious concrete with a rock storage chamber underneath with 6" per PVC to drain into an existing inlet.
Excavating the stone storage area. To the right in the pic is where the old curb was we removed, the new curb will go back in the same place.
Using the 279 to clip the bottom after the excavator dug it out.
Filter fabric down, placing some #2 stone that makes up the water storage area underneath the pervious concrete.
The design called for 2 runs of 6" perf PVC highway under drain. Pipe installed and covering with rock. A little track loader love finding it's way into the picture.
Connection to the existing inlet. At the time this pic was taken we were waiting on 2 6" T's to connect the two runs together.
Closer look at the connection to the existing inlet. One of the crew is cleaning out the existing inlet. We had to lower the grate about 6" to meet the new plans. Luckily there were 3 runs of brick on top of the lid so we knocked that off and re-set the grate.
Once we installed the T's and tied the two 6" lines together, we used some recycled DGB from the old parking to to bed the pipe and bring the bottom up to grade.
On a side note the Husky K760 has been a very good saw. In three years all we've replaced is the pull start assembly which was $60 at the local shop, not bad for 3 years of abuse errr I mean use.
