Most first-time builders picture their lot getting cleared in a single dramatic afternoon, dozer pushing trees into a pile, and the next morning the foundation guys show up. The reality is closer to a two- to four-week sequence with a lot of small decisions, weather watching, and coordination between trades. Skipping steps or compressing them is the single most common reason a build starts on rough footing.
Here's how the sequence usually runs on a typical wooded residential lot in the Greater Chattanooga area.
Before anything happens, the builder, owner, and excavation contractor walk the lot together with the site plan. The conversation covers:
This walk usually surfaces a half-dozen small issues that would have become big issues during construction. It's cheap insurance.
Tennessee 811 and Georgia 811 marks happen at least three full business days before any digging. Both are free. Private utilities, propane lines, irrigation, an old well, anything you installed yourself, you're responsible for identifying.
If the lot has had previous structures, ask the title company or county GIS for any record of septic systems or old service entries. Surprises here can cost real money.
Before the first tree goes down, the entrance gets built. That usually means a gravel pad at the road, often over a geotextile fabric, sized to keep mud off the asphalt. In places like Hixson and Ooltewah where county inspectors actually look at this stuff, a proper construction entrance can be the difference between a smooth permit experience and a stop-work order.
Silt fence goes along the downhill edges of disturbed area. If the lot has a creek or wet weather drainage, that gets buffered.
The actual clearing happens in order from biggest to smallest:
Anything organic that will end up under a foundation, slab, or driveway base has to come out. Grinding stumps in those areas is a future settling problem.
The top six to twelve inches of soil on most Greater Chattanooga lots is the only soil you can grow grass in. Once construction starts churning everything underneath up, that topsoil becomes precious. We strip it from the disturbed area and stockpile it on a corner of the lot that won't get driven on, covered or seeded if it'll sit through a long winter.
Underneath the topsoil, you're usually looking at red clay or clay over weathered rock. That's the layer that gets graded.
Rough grading shapes the lot for drainage and gets the building pad close to its final elevation. The goal is:
On sloped ground common around Signal Mountain and Lookout Mountain, this step often involves cuts and fills measured in feet, not inches.
The pad itself gets brought to grade, with imported structural fill compacted in lifts if needed. Compaction matters; a soft pad becomes a cracked slab. For a deeper look, see the building pads pillar.
Pad-ready means the foundation contractor can start footings the next morning. If you've made it this far cleanly, the rest of the build runs faster.

On a typical residential lot, two to four weeks depending on size, density, and weather. Bigger or steeper lots take longer.
After. The builder needs to weigh in on house placement, driveway location, and pad elevation before the chainsaws start.
Tell us during the site walk and we'll plan equipment routes accordingly. Selective clearing is normal.
Yes. Boundary disputes after the fact are expensive and emotional. Get the corners marked before clearing.
Yes, and often goes faster because ground is firmer and visibility through bare trees is better. Weather windows are tighter.
