Planning a pool in East Tennessee: what to sort out first

Access comes first, and it surprises people

A gunite pool needs an excavator on site, then concrete trucks, then a gunite rig with a hose run. If the only route to the back of the property is a four-foot gate between the house and the property line, that constraint decides more about the project than the pool shape does.

Walk the route before anything else. Look for gate width, overhead power and limbs, soft ground that will rut under a loaded truck, septic fields and lines that cannot be crossed, and how far the gunite hose has to reach. None of these stop a project. All of them change how it is priced and sequenced, and all of them are cheaper to solve on paper.

Slope is the East Tennessee tax

Flat lots are the exception here. A pool needs a level plane, so on a sloped site you are also buying whatever holds that plane up — retaining structure on the low side, cut and possibly rock removal on the high side, and a drainage plan that moves water around the whole assembly rather than into it.

The useful thing to know early is the fall across the pool footprint. Measure the drop from one corner of the intended area to the opposite corner. Under about two feet and you are in ordinary grading. Beyond that and retaining structure becomes a real line in the project rather than a detail.

What is under the grass

Blount and Sevier counties sit on limestone and shale, and rock depth can change dramatically inside a single lot. Rock excavation is the most common source of surprise on a mountain pool project, and it is the one thing no one can price accurately by looking at the surface.

The free first step is the NRCS Web Soil Survey, which will tell you the mapped soil series and general depth to bedrock for your parcel. It is not a substitute for a test hole, but it tells you whether to expect a conversation about rock at all.

• Clay-heavy valley soils — good bearing, poor drainage, plan the water route deliberately
• Thin slope soils over rock — the rock question, and often the retaining question, arrive together
• Fill from a previous build — has to be identified before anything structural sits on it

Sun, and where the pool actually wants to go

A pool in shade from three in the afternoon is a pool that runs several degrees colder and gets used less. Before fixing a location, watch where the sun sits across the property in the afternoon, not the morning, and remember the tree line will be taller in ten years than it is now.

The prevailing answer here is to favour the southern and western exposure and keep the deep end away from the heaviest leaf drop, which saves a great deal of skimming every autumn.

Setbacks, permits and the barrier requirement

Local zoning sets how close a pool and its equipment can sit to property lines and structures, and a residential pool requires a barrier — fencing, self-closing and self-latching gates, and specific rules for any door opening directly onto the pool area. Check your county or city requirements and your HOA covenants early; the barrier is not an optional add-on and it belongs in the plan from the start.

Then, finally, the pool

Once the site is understood, the pool decisions get easier, because most of them are now constrained. How you intend to use it — laps, entertaining, small children, a spa on the schedule — drives depth profile, step and bench placement, and where the decking needs room. Take the design conversation in that order and very little gets revisited.
