Water infiltration test

Yesterday Emily, Matt and I dug a 3' x 3' x 3.5" hole at the site of the proposed rain garden at the north end of the project.

This is the latest request from the PUC in order for them to release our grant funds and get started on the project.

It took 2 hours to dig the hole in the very rocky ground, then we soaked the entire are with a sprinkler for an hour or so to saturate the ground before the test.

After that Andrea, our landscape architect from DPW came by the help us perform the test.

We filled the hole and timed the draining - every 60 seconds we took a reading until it was empty. This is supposed to be repeated three times.

With a bit of luck this is the final hurdle from PUC.
