'''Note:''' where many rows of chambers are being installed, it may be advisable to construct the chamber rows piece-wise as the application of perimeter stone progresses to provide space for excavators to apply the stone from on top of the stone foundation. See the adjacent photo for an example.

Mistakes to Avoid:
'''Mistakes to Avoid:'''
*Equipment on the perimeter stone – Perimeter stone should be applied with a stone conveyor or excavator from the outside of the LID footprint or on the stone foundation.
*Equipment on the perimeter stone – Perimeter stone should be applied with a stone conveyor or excavator from the outside of the LID footprint or on the stone foundation.
*Uneven perimeter stone – Perimeter stone must be applied such that the depth of stone on one side of the chamber is not unacceptably higher than the other. Refer to design details.
