How fast does a car have to be going on Snell Isle Boulevard NE before the City of St. Petersburg will consider physically slowing it down? There is a published answer. It is not the one neighbors heard this summer.
On June 29, 2026, Bay News 9 reported that residents had asked the city to deal with speeding on the boulevard. The city told one resident that the road carries nearly 8,000 vehicles per day, so speed bumps would not work at that volume. The city's Neighborhood Traffic Calming Program decides these requests with a written set of criteria. Those criteria contain no daily volume cap for speed humps or speed tables. On paper, the boulevard's case depends on measurements, chiefly a speed reading, and those measurements sit inside two traffic studies the city has not yet made public.
What the city said in June
The Bay News 9 story describes the boulevard as a straight road with heavy traffic. The vice president of the Snell Isle HOA told the station that speeding is the top complaint he hears from residents.
"People think this is a speedway. It goes out to Shore Acres and Venetian Isles. There's a lot of traffic that goes through here."
That quote, also from Bay News 9's report, explains why so many cars use the road. The boulevard is the way in and out for two more waterfront neighborhoods past Snell Isle itself. One resident told the station she believes nearby construction and drivers heading to other neighborhoods have made it busier.
The city's answer had three parts. Speed bumps were ruled out because of volume. Two traffic studies in the area were being finalized. New radar speed signs were promised, and the city was still working with utilities to get them installed.
What the program's published rules actually test
The city posts the Neighborhood Traffic Calming Program on its Neighborhood Improvement page. The program covers speed humps, speed tables, raised intersections, median islands, chicanes and other measures meant to cut speeds or discourage cut-through traffic. The FAQ beneath it sets out which streets qualify and when.
Here is how Snell Isle Boulevard compares with each published test. The road's classification and speed limit come from the city's own Streets dataset, which shows a data update on October 5, 2026.
| Program test | Published threshold | Snell Isle Boulevard NE |
|---|---|---|
| Street type | Local road or neighborhood collector | Current road type "COLLECTOR"; future category "Neighborhood Collector, City Road" |
| Speed limit | Below 35 mph | 30 mph |
| Speeding trigger | 85th-percentile speed more than 8 mph over the limit, or more than 35 mph, in either direction | No published measurement |
| Cut-through trigger | More than 20% of daily traffic in one hour, with more than 400 vehicles per day | No published hourly breakdown |
| Daily volume cap | None stated | Nearly 8,000 per day, per the city in June 2026 |
The boulevard meets the speed-limit test on the city's records. On street type, the dataset uses two fields. The current road type is "COLLECTOR," and the future category is "Neighborhood Collector, City Road." Whether the boulevard counts as a neighborhood collector under the program today is the city's call. Volume shows up in the published rules only inside the cut-through test, where it works as a minimum. That test requires a street to carry more than 400 vehicles a day, and 8,000 is twenty times that.
The speed number that would decide it
The cut-through test asks whether more than 20% of a day's traffic arrives within a single hour. The speeding test, which is the complaint residents raised, uses the 85th-percentile speed. The city's FAQ defines it as the speed at or below which 85% of traffic travels. If that number is 30 mph, 15% of drivers are going faster.
On a 30 mph street, the two speeding triggers work out differently. "More than 8 mph over the limit" means above 38 mph. "More than 35 mph" is the lower bar, so it is the one that applies here. The city measures each direction separately, and only one direction has to qualify. If the 85th-percentile speed is above 35 mph in either the inbound or outbound lanes, the boulevard meets the program's speeding criterion.
That is a measurement of the slower majority of drivers. A few cars going very fast late at night won't move it much. A steady habit of driving 37 or 38 mph on the straight stretch will.
None of the public coverage reported a speed or an hourly traffic breakdown. The two studies the city described in June are the likely place where those figures live.
Where a volume concern could come from
City guidance does talk about volume in other places. The Neighborhood Greenways Toolbox, dated January 2024, targets no more than 1,500 vehicles per day on designated greenways. It allows some higher-volume segments and says traffic calming matters especially on those. That figure is a design target for bike-friendly routes. It does not limit where humps can go.
The same toolbox shows that vertical devices come in more than one form. Speed cushions have cutouts sized for emergency vehicles, and the toolbox describes them as a possible preferred option on emergency-response routes. It also lists curb extensions, planters, pinch points, traffic circles, turn restrictions and diverters, and gives typical device spacing as 200 to 600 feet. For a through route like the boulevard, a city engineer has more choices than a classic speed bump.
The city's 2019 Complete Streets Implementation Plan also prefers design over enforcement. It says constant police enforcement is not a reasonable citywide answer to speeding. It calls for speed studies and street design that slows drivers on its own wherever operating speeds exceed targets. That plan also names resurfacing and restriping as moments when lane space can be reassigned.
Snell Isle already has a traffic plan on file
The city's traffic calming page links to roughly 90 neighborhood traffic plans. One is the Snell Isle Property Owners Association Traffic Plan, a one-page drawing dated March 20, 2019. Its legend lists chicanes, traffic circles and traffic islands as calming features, and the map labels Snell Isle Boulevard NE.
The digital file has limits. It doesn't show where each feature sits, whether a given feature was built or only proposed, or any traffic counts or speeds. The city also keeps separate plans for the Shore Acres Civic Association and Venetian Isles. The city's listing doesn't say how those plans relate to the traffic that reaches them along Snell Isle Boulevard.
The 2019 plan means the neighborhood has been through this process before. Any new measure on the boulevard would be added to a plan that already exists.
What is still open as of October 12, 2026
No public update has surfaced since the June report. The open items look like this:
- The two traffic studies. The city described them as being finalized in late June. No results have been published in news coverage or in the materials reviewed for this post.
- The radar speed signs. As of June 29, these were waiting on utility coordination. No installation has been confirmed since.
- The association calendar. The September 2026 issue of The Panther, the Snell Isle Property Owners Association newsletter, lists board meetings on the first Wednesday of each month. That issue does not include a boulevard update.
- Who can ask for an evaluation. The program FAQ says requests go to the city's Neighborhood Transportation Coordinator. The person asking must own, rent or otherwise live at a property on the street in question.
The rest of the boulevard's calendar
Two scheduled events will add traffic on or right next to the boulevard before the studies are likely to settle anything.
The city's water main replacement project runs along Beach Drive NE from 5th Avenue NE to Coffee Pot Boulevard NE. It then continues northwest on Coffee Pot Boulevard to just past Elm Street NE, and covers parts of North Shore Drive NE. The posted schedule had construction starting in spring 2026, customer connections in early 2027, and completion in spring 2027. The page says closures and detours will be announced ahead of time but lists no specific dates.
On Thanksgiving morning, Thursday, November 26, 2026, the Coffee Pot Turkey Trot 5K loops around Coffee Pot Bayou. North Shore Elementary presents the race, which starts at 7:45 a.m., with the start and finish behind the school at 200 35th Avenue NE. The race FAQ mentions road closures and a water stop near the Snell Isle Bridge, but doesn't list which segments close or for how long.
The bridge itself is on a longer timeline. The city's FY26 capital planning workbook, in a memo dated April 11, 2025, carries the Snell Isle Boulevard NE bridge over Coffee Pot Bayou as project 157191. It shows estimates of $2 million in FY 2028 and $1 million in FY 2029. Those are planning numbers, not a construction contract. Even so, whatever the city decides about calming the boulevard will eventually meet a bridge project at its eastern end.
At Marsh Bilby, we look at a street the way an appraiser does. That means checking its classification, its traffic and its pending city decisions along with its curb appeal, because all of them affect what a home there is worth.
