"The town charter even states they formed the town to preserve the peace and quiet," Louisville resident Josh Stamey told WBIR at a public meeting about a proposed development at Louisville and Topside roads. "So this didn't become Maryville or Alcoa; it's supposed to be protected from all of this development. Kind of like an island from the insanity."
The charter is the reason people usually give for that island. The plumbing does more of the work. Louisville has no central sewer line like Maryville or Alcoa. The town's one serious attempt to get a sewer line stalled because the regional treatment plant had no room left. If you're comparing Louisville with its neighbors, that shortage explains more about the town's lot sizes, its thin commercial corridor, and the grocery store that doesn't exist yet than any price chart will.
The line that was supposed to come down Topside Road
The original plan was practical. A sewer line would run from the Smith & Wesson wet well to businesses on Louisville and Topside roads, and South Blount Utility District would install it during road work. The wastewater would have gone to the Maryville Regional Wastewater Treatment Plant, which serves Maryville, Alcoa and Knox Chapman Utility District.
That plant ran out of room first. According to the Town of Louisville, the extensions to Smith & Wesson and to new housing along Topside used up the available treatment capacity before Louisville's extension could move forward. Some new development near the town did get a sewer connection. The project meant to serve the town's own commercial corridor did not.
The money moved on to other uses. In a September 14, 2026 post, the Town explained that the $2.2 million behind the project was a Blount County grant, not town money. After the sewer project stalled, Blount County and South Blount Utility District, at Mayor Jill Pugh's request, redirected that grant to upgrade water mains on Mentor Road in Louisville. The Town's own share, about $600,000 in ARPA funds, was never spent on sewer. It sits in an LGIP account and had grown to $695,588.49 as of July 31, 2026.
The decisions since then, in order:
- April 30, 2024. The Town reported that the regional treatment capacity had run out after the Smith & Wesson and Topside housing extensions.
- August 2024. Landowner Jesus Yanez offered up to five acres for the Town to consider a sewer plant that would serve the commercial corridor. The Board of Mayor and Aldermen voted unanimously to get updated costs and to give area businesses information about a possible private sewer system.
- After that vote. No land was transferred, no property agreement was signed, and no agreement committing the Town to build a plant was executed.
- January 2026. The Board unanimously adopted zoning changes that raised lot minimums and confirmed there is no general mixed-use district.
- September 2026. The Town posted two "Facts vs. Fiction" statements, one on sewer and one on development, in response to questions from residents.
Why the 2026 zoning rules hold
The January zoning changes set out the figures below, as summarized by the Town on September 18, 2026.
| Rule | Requirement | In acres, roughly |
|---|---|---|
| R-1 lot with public water | 30,000 sq ft minimum | about 0.69 acre |
| R-1 lot with well water | 40,000 sq ft minimum | about 0.92 acre |
| Each additional family, where permitted | 30,000 sq ft per family | about 0.69 acre each |
| NC-1 and C-1 commercial lots | 30,000 sq ft minimum | about 0.69 acre |
| Height, non-single-family residential and NC-1/C-1 commercial | 40 feet maximum | n/a |
The per-family rule replaced some earlier lots that allowed 20,000 square feet. The C-1 commercial district allows only one dwelling unit, and it has to be part of another permitted use, mainly for a business owner, manager or security staff.
Those lot sizes fit a town without central sewer. A rule that gives each household roughly two-thirds of an acre doesn't create pressure for sewer, and with no sewer there's little reason to revisit the rule. The Board is working on an updated master plan, so the numbers could change. As of late September 2026, they stand as listed.
For a buyer, this matters most with land. Someone who buys a large Louisville parcel planning to add a second home for family should work from the 30,000-square-foot-per-additional-family figure, not from older 20,000-square-foot lot patterns. Confirm with the Town how the rule applies to a specific parcel before you close.
What Louisville Village Commons is waiting on
The clearest example of this setup is the proposal for the corner of Louisville and Topside roads. At a community forum, architect and planner Bob Koch presented Louisville Village Commons on behalf of Jesus Yanez, who owns the roughly 33-acre parcel at 2942 Louisville Road. Yanez told The Daily Times he has had many offers over the roughly 20 years he has owned the land to develop it for large retail and commercial uses. "I just want to build something for my community, for my kids, to be proud of," he said.
The concept divides the land into thirds: residential, commercial and open space. It calls for 40 housing units, about 148,000 square feet of retail and office space, and a park with walking trails and a roughly 4-acre lake that would also handle stormwater. The biggest tenant would be a neighborhood grocery of no more than 18,000 square feet. Koch said a grocery was what came up most when the team asked the community what it wanted: "something smaller than, say, an Ingles," closer to the size of a Whole Foods or Fresh Market.
Sewer comes before any of that. The developers would have to build their own line, partner with the Town on one, or install a package treatment plant. The Daily Times also reported a less obvious point. Once sewer is solved, the developers are technically allowed to build everything presented except the homes. The 40 residential units need a rezoning, or a mixed-use district the town doesn't have yet.
So the commercial half of the project, including the grocery, depends mainly on a sewer decision. A zoning vote is not the main hurdle.
That decision is still open. Mayor Pugh told WBIR the proposal had not been considered by any town officials or gone through any official process. She said the aldermen had pursued a public sewer for the commercial corridor on Topside and Louisville roads, "but they have not really made a decision on any of it at this point." Residents at the meetings raised concerns about public money. Resident Anna Gibson told WBIR she doesn't think "our public funds should be able to go to someone's private development." Others said Topside Road traffic had already been pushed past capacity since Smith & Wesson was built. We found no approval, rezoning application or withdrawal for Village Commons as of this writing.
The grocery shopping that has opened so far
In the meantime, local food shopping in Louisville arrived in a smaller form. McCarthy's Market opened in summer 2026 at 3006 Samples Road, across the street from Louisville Mercantile. It's owned by siblings Owen and Lauren McCarthy and sells local produce, meat, dairy and baked goods, with a full coffee bar and an ice cream counter. The siblings ran a mobile farm stand out of a renovated school bus for two years before opening. Along the way, they said, they found that Louisville was missing "a place to shop local products while being together."
A farm store doesn't replace an 18,000-square-foot grocery, and it isn't trying to. It does show what kind of commerce has opened in Louisville while the corridor sewer question stays open.
Questions to ask about a Louisville property
Because the infrastructure shapes the town, it also shapes individual deals. Before you write an offer, get answers to these:
- Sewer or septic? Find out whether the home connects to a sewer extension or relies on an onsite system. That answer changes what your inspection needs to cover.
- Public water or well? It sets whether the R-1 minimum is 30,000 or 40,000 square feet. That affects any plan to divide the lot or add a dwelling.
- How close is the Topside and Louisville Road corridor? Any commercial growth from a future sewer decision would show up there first. Residents have already raised traffic concerns on that stretch.
- What's the latest from the Board? Board of Mayor and Aldermen meetings are open to the public on the second Tuesday of each month at 6 p.m. The next two fall on October 13 and November 10, 2026.
None of this is legal advice. Lot-specific questions belong with the Town and your closing professionals.
