It was a soil thing that is required by where we live which was an $800 cost. 

The three issues I know about with Texas are mold (leave ac on when vacant) high property tax ( ever adjusting) and foundations ( clay soil).

The topography ( how hilly it is ) and the soil composition will determine how much of it is buildable allowing with density allowances for the zoning.

They have a monthly meeting the second Wednesday of the month in Sandy.

When I put the block box around it I ran a perforated pipe out 10 feet and made a small drain field to make sure no water can build up in it , and the soil is sand .

Hello Sandy,Sorry I'm so late getting back to you - just discovered your question.I've been using Tenant Tracker and Investor Books made EZ since 2008.

Do they treat the soil below?

This will be determined based on the soil quality-import-export and required stormwater management.
