June Lake is the biggest thing being built in Spring Hill, and it's surprisingly hard to get a straight answer about what's actually happening there. The developer's website sells the vision. City meetings dole out the details a half-hour at a time. So I went through this year's building permits, planning commission transcripts, and city records and put it in one place.

Two things in those records haven't been announced anywhere, as far as I can tell. More on that below.

What June Lake is

June Lake is a 775-acre master-planned development on Spring Hill's northeast corner, west of I-65 around the new interchange. The full entitlements, per the city's announcement of the project, run to more than 2,900 residential units, 3.9 million square feet of Class A office space, nearly 1.3 million square feet of retail and restaurant space, and 400 hotel rooms — built out over many years. Southeast Venture manages the development; ground broke in June 2021.

The road you drive to get there is part of the project. June Lake Boulevard is the 2.25-mile connection TDOT built from Buckner Lane to Lewisburg Pike along with the diverging-diamond interchange at I-65. It already carries about 17,000 cars a day, per traffic counts the developer cited at a city meeting this spring.

Homes: building fast

The residential side is the part that's visibly moving.

Saddlewalk is under active construction. July's city permit report shows a steady stream of new single-family permits on Marston and Saint Clair Avenues — typical new builds running around 3,800 square feet with construction values in the $630,000 range. Signature Homes' first phase here was announced at 400 homes with an amenity center.

Windfall is next. It's roughly 120 acres south of June Lake Boulevard, planned for about 400 more single-family homes, also by Signature Homes. Its first phase was approved in mid-2025, and this spring the city approved downgrading the road that will serve it from a planned five-lane arterial to a three-lane collector with on-street parking — the area was originally flagged for possible commercial use and no longer needs the bigger road.

Here's where that new road actually goes, because this will matter to a lot of people: the collector runs south from June Lake Boulevard through Windfall and connects to where Spring Station Drive currently dead-ends at the top of Wades Grove. The mayor confirmed the connection point at an April board meeting. If you live in Wades Grove, your dead-end street eventually becomes a through-connection into June Lake. One alderman pressed the developer on whether it could become a cut-through to commercial areas; the answer was no — with Windfall going residential, the road serves the ~400 new homes and doesn't loop to anything bigger.

Two conditions attached to the road approval are worth remembering. A new traffic signal is required at June Lake Boulevard and the collector road — the intersection on the boulevard's south side where the new road tees in. Staff pushed for it because northbound drivers leaving Windfall will be turning left across two lanes of 40-mph traffic, and the signal also gives walkers and cyclists a protected crossing. It's timed to go in when that section of road is complete. And second, the greenway trail through Windfall must be finished and inspected before the new road opens. The mayor added that condition himself.

Pod A, one of the original phases, had a small footnote in August: six of its 76 lots were flagged as "critical lots" with driveways steep enough to require engineered site plans.

Businesses: the commercial village, and two names nobody announced

The first real business cluster is Pod K, a group of roughly a dozen commercial and office lots at June Lake Boulevard east of Buckner Lane. Its streets, water, and sewer are done — the infrastructure bond was converted to a maintenance bond in May. Here's what's landing on those lots:

  • Image Studios, Spring Hill's first salon-suite concept, is building now at 3070 June Lake Boulevard — plumbing and mechanical permits were issued in July. The owner told the city board he paid $1.88 million for the parcel.
  • The June Lake Collective, approved in April, is two single-story buildings totaling about 15,500 square feet, each designed for two to four tenants, with room for up to roughly 9,000 square feet of restaurant space between them. This is where June Lake's first restaurants will most likely show up. No tenants named yet.
  • Liberty Federal Credit Union — this is the first thing I haven't seen reported anywhere. Nobody has announced it, but the city's July permit report says it plainly: an erosion-control permit issued June 24 and a grading permit issued July 20, both for "June Lake Pod K Liberty Federal Credit Union." Site work permits mean a branch is coming.
  • A dental office — the second unannounced one. A July 29 erosion-control permit is titled "June Lake Pod K Dental." No business name attached yet.

One thing tempering the pace: Spring Hill's sewer moratorium. June Lake holds one of the development sewer allocations the city froze in place in January, and the developer told the planning commission that Pod K's remaining lots will come forward as allocation allows — some may simply wait. Credit where due, though: at an April board meeting, the Image Studios owner publicly thanked June Lake's developer for sharing sewer capacity with the small businesses that bought its outparcels, and contrasted it with another Spring Hill shopping center whose developer wouldn't.

The trail tunnel that's already there

My favorite detail in the records: there is a pedestrian passage already buried under June Lake Boulevard, and it connects to nothing.

When TDOT built the interchange and the boulevard, the city approved a change order to bury a 12-foot-wide, 9-foot-tall pedestrian culvert just west of I-65 — so the development's planned two-mile greenway along Aenon Creek could cross under the road instead of at street level. It was cheaper to build it while the road was under construction than to ever add it later. The cost was $502,228.54, and under a 2022 reimbursement agreement, June Lake's development entity agreed to repay the city the full amount.

About 3,000 feet of the greenway exists so far, built as development proceeds. June Lake has no bike lanes by design — the plan routes cyclists and walkers onto the wide multi-use trail instead, which is why that buried crossing matters. Until the greenway reaches it, Spring Hill has a half-million-dollar underpass sitting in the dark under the boulevard, waiting.

Roads to watch

Beyond the new signal coming at the collector road, the big one is Buckner Lane: the final phase of its widening is underway, and the city expects the full five-lane road — with trails and sidewalks — to open later this year, running from Thompson Station Road near June Lake down to Duplex Road. That's the main north-south connection for everyone who lives in or near the development. Fire coverage is already in place: Station 4, opened nearby, serves June Lake and has cut response times enough that the city credits it with contributing to at least one save.

What to watch next

Three things. First, tenant announcements for the June Lake Collective — those two buildings are where the "what restaurants are coming" question gets answered. Second, whether the Liberty Federal Credit Union branch and the dental office get formally announced now that their site work is permitted. Third, the sewer allocation report city staff promised for September, which will show how much capacity June Lake and every other allocation holder is actually using — and how fast the rest of Pod K can build.

I'll update this post as the records change.

This article draws on my review of Spring Hill's 2026 board and planning commission meeting records, the July 2026 building permit report, the 2022 TDOT reimbursement agreement, and the city's June Lake project announcements. Figures are as stated in those public documents.
