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 hadn't been announced anywhere, as far as I could tell. Both have names now — the dental office turned out to be Heartland Dental, and the credit union branch is confirmed as Liberty Federal — and the developer's summer update added a lakeside trail and a cemetery preservation deal on top. Details below.

Last updated August 21, 2026. This is a living tracker — I revise it as permits, approvals, and announcements land.

  • August 21, 2026 — Heartland Dental named as the Pod K dental office; the June Lake Collective retail reveal; the lakeside June Lake Trail and the Pointer Cemetery preservation agreement added.
  • August 18, 2026 — First published, from 2026 permit records: Saddlewalk and Windfall status, five named Pod K businesses, the Wades Grove road connection, and the trail tunnel that's already buried under the boulevard.

What June Lake is

June Lake is a 775-acre master-planned development in Spring Hill, Tennessee — on the city's northeast corner in Williamson County, west of I-65 around the new Exit 55 interchange. (It has nothing to do with the June Lake in California; this one is off Buckner Lane.) 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.

How far along is it? The city's own accounting gives a precise answer. A September 2025 list of vested sewer commitments the city compiled for state regulators shows June Lake with 2,579 of its 2,926 committed homes still to build — meaning roughly 350 homes had connected by last fall — and the entire commercial program still ahead: all 1.28 million square feet of retail/restaurant space, all 3.9 million square feet of office, and all 400 hotel rooms. After five years of construction, June Lake is about 12% built on homes and 0% built on everything else. Those commitments are also a big part of why the city's sewer moratorium will outlast the plant fix — June Lake alone holds more promised capacity than most of the rest of the city combined.

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. The developer's August status: Pod B is fully sold out with all homes on track to close by end of Q3, Pod A move-ins started in July, and Pod E's first townhome buildings are framing now with roughly ten more starting in Q3. Three model homes grand-open in October — one alley-load home in Pod A and two townhomes in Pod E.

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.

Lifestyle Communities, the 509-unit rental phase announced in January 2025, remains committed but its timeline has slipped with the sewer moratorium. The developer says Phase One moves forward as soon as capacity is available. Meanwhile Solstice, the 227 apartments already open at 2400 Buckner Lane, picked up a new perk: June Lake is now on the Street Food Finder food-truck rotation.

Businesses: five names in the commercial district

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 — and per the Collective announcement, site work across the whole district is complete, with businesses actively seeking building permits. Five projects are now announced:

  • 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 got its formal announcement in July: two single-story multi-tenant buildings totaling 15,823 square feet at the corner of June Lake Boulevard and Buckner Lane, designed by SV Design, pre-leasing now with completion anticipated summer 2027. This is where June Lake's first restaurants will most likely show up — up to roughly 9,000 square feet of it can be restaurant space, and the developer says retailer announcements are coming.
  • Heartland Dental — that July erosion-control permit titled "June Lake Pod K Dental" has a name now. WMG Development will build a 5,000-square-foot office with 15-plus exam rooms along June Lake Boulevard, with construction expected to begin this fall. It's the first healthcare provider at June Lake; Heartland Dental is one of the largest dental support organizations in the country, supporting more than 1,700 practices.
  • Liberty Federal Credit Union — the branch I first pulled out of the permit records (an erosion-control permit issued June 24 and a grading permit issued July 20, both for "June Lake Pod K Liberty Federal Credit Union") is now formally approved by the city, with construction beginning this spring per the developer.
  • The Goddard School — a childcare provider rounding out the district lineup.

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.

Two new amenities: a lake loop and a cemetery saved

The developer's summer update added two items that weren't in any city record I'd read.

June Lake Trail: construction plans for a paved one-mile loop around the lake are awaiting permitting, with a scenic overlook, landscaping improvements, and upgrades to the dam and spillway included. Opening is expected spring 2027, and future plans connect it to the Aenon Creek Greenway — which the developer now sizes at more than 2.5 miles when fully complete. That's the same greenway whose half-million-dollar underpass is already buried under the boulevard, below.

Pointer Cemetery: the Alexander family has entered into an agreement with the Battle of Franklin Trust — the group that operates Carnton and the Carter House — to preserve and maintain the historic cemetery on the June Lake property and open it to the public. Quarterly tours are expected to launch in 2027.

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 — the developer says they're coming, and those two buildings are where the "what restaurants are coming" question gets answered. Second, fall groundbreakings: Heartland Dental is expected to start construction this fall, and the rest of the district's projects are moving toward breaking ground as permits clear. 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, the city's June Lake project announcements, and June Lake's developer updates — including the Heartland Dental announcement (May 26), the June Lake Collective announcement (July 15), and the Summer 2026 update (August 3).
