Georgetown has many sites available in areas that require a septic tank. The sites will require a percolation test. This is a soil test to determine absorption rates. Based on this test, you will have to get an approved septic design. The septic design cost is about $1,000, but the septic systems required for new housing cost many thousands of dollars. Whether your site is in a development, residential neighborhood, or raw land above Lake Georgetown, you will want to consider soil tests.
In Georgetown, you have limestone that can increase excavation and prep costs. Plus, hundreds of limestone caves are in the area. Inner space Caverns was discovered accidentally during the construction of I-35 when a construction worker lost his hammer in a hole and looked down and saw the cave. Spend a few thousand dollars for a soil test before committing to buy unless you are in a neighborhood or development you can expect to be comparable to a nearby neighbor.
Site selection goes hand in hand with housing design, each an extension of the other. If you like to be awakened by sunlight, place your bedroom to catch the morning sun. Will the tree that "makes the place" have to be removed to build the house?
Check with Dan Amon before committing to purchase the site. Some problems may be out of sight; the ground beneath your feet may hold surprises. Dan can evaluate the unique challenges of building on a particular site. Some house designs will not work with some home sites and vice versa. Unless you are absolutely set on a particular house, it is easier to select your site first and then design the house. In site selection, you need to involve your architect and builder.
