I'm consumed with returning our yard back to good condition after six years of rental neglect left it overgrown or dead. One task: remove the back lawn and replace it with a brick patio. Rarely for SoCal in June, over 1" of rain fell last weekend, which softened the turf enough to remove easily. Well, easier than if it were hard and dry. So I eagerly started in with a shovel and old muscles and fairly quickly excavated 3/4 of the 600 sq.ft., only to realize I'd created a problem.

Take a close look...
