I don't have to tell you it's hot and dry outside.  As I drive around the Houston area, it reminds me of when I lived in California during their drought years.  Lots of brown and brittle lawns.  Of course on the West Coast the ground doesn't crack and shrink like it does here. 

Remember to protect your foundation with a soaker house around your home.  This simple precaution can save you thousands down the road and avoid a cracked foundation.  Here is what one article suggests to water your foundation:

"Dry soil problems can be slowed by using a soaker hose to provide a consistent, but not flooding, water source to the soil immediately surrounding the home’s foundation, said Michael Goldschmidt. For best results, place the soaker hose around the perimeter of the house 8 to 18 inches outside the foundation.

“Shifting ground can crack foundations, especially during drought conditions. This damage often shows up as cracks or separations around doors and windows or brick veneer,” Goldschmidt said.

 Before using a soaking hose, inspect the exterior side of the foundation for existing cracks. The cracks should be cleaned and filled with foundation waterproofing, which is available in most hardware stores or lumber yards, he said."

To this day I practice many of these hints.  http://prep4agthreats.org/Assets/Factsheets/Drought-and-Your-Home.pdf
