07/14/16 – During heavy rain some of the drains in the courtyard have been backing up. Attempts to find and fix the blockage have met with uncertain results. Instead of chasing the problem with more time and money, CMI's plan now is to install a French drain (a perforated pipe that slowly allows water to escape into the soil), fill the hole in the landscaping, and wait for wet weather to find out if more work needs to be done.
UPDATE: 08/04/16 – The hole has been filled.
