27th Avenue Makeover Plan 90% Complete

This past Tuesday, the county presented its 90% completion for the proposed 27th Avenue makeover project. There has been little deviation from the 30% rendering, which calls for the following improvements:

  • Addition of bike lanes
  • Addition of on-street parking
  • Removal of most private, on-site parking
  • Addition of tree-planted median (and more shade trees for sidewalks)
  • Addition of oval-shaped traffic circle at the intersection of Day, Tigertail, and 27th

While earlier renderings more often centered around parking controversy, the newest lightning rod is the traffic circle. Several citizens and business owners still don’t believe the traffic circle will work.

”You have to remember people don’t like change, and this is something that’s foreign to them,” - Delfin Molins, a spokesman for the Miami-Dade County Public Works Department.

It’s true - many Groveites are terrified of change. However, I’d be surprised if most are not fully supporting this project by the time the final draft is unveiled. I really think this project is quite progressive for Miami/South Florida standards in the way it focuses more on improving the pedestrian realm than making the street a traffic sewer.

As for the concern about the traffic circle, I’m pretty confident it will be beneficial to Center Grove residents and visitors alike. As long as it’s engineered by the specs public works has planned, it should do a pretty good job mitigating congestion on 27th and Tigertail while not compromising easy pedestrian crossings. The shape and design of this “circle” should ensure that cars cannot speed through it. People shouldn’t worry about it becoming a wild “free-for-all”, because it is not designed to be a large rotary similar to the Cocoplum Circle at Le Jeune and Sunset in Coral Gables. Miami drives can be dumb…and crazy, but even they can handle a traffic circle this simple. Plus, Day Ave should not experience an appreciable increase in thru-traffic as long as it changes to one-way eastbound.

My biggest disappointment with this project, however, is that the intersection of 27th Ave and US-1 is being ignored. The sidewalk and bike lane improvements are great, but this intersection is one of the most hostile in all of Miami for pedestrians and cyclists. Without design upgrades to improve safety and aesthetics at this intersection, the Grove Metrorail station remains effectively alienated from the wonderful 27th Avenue improvements. It’s a classic example of Miami’s seemingly inextricable fragmentation - especially when it comes to transit and land-use planning.

27th Avenue Update #2

I attended the Cocoanut Grove Village Council meeting at City Hall last night, and was pleasantly surprised by the county’s renderings for the beautification of SW 27th Avenue in the Grove. Although it is only in the 30% completion phase, it appears to be moving in a positive direction. Unfortunately, I do not currently have pictures of the proposal, but I’ll share a few of the major tenets of the project:

  1. Sidewalks: It appears that after years of embarrassing pedestrian-infrastructure, the county is planning on implementing sidewalks on both sides of 27th avenue in a uniform manner along the entire stretch of road south of US-1. It’s sad that I have to even mention sidewalks, given that they are as fundamental a part of a city as any piece of infrastructure, but in Miami this is never a given. I am a little disappointed that the new sidewalks are only proposed to be six feet wide; I would like to see 10-12 feet sidewalks throughout the avenue.
  2. Bike Lanes: Groveites, as well as any Miamian who frequents the neighborhood, should be very happy to learn that bike lanes are proposed for both sides of 27th Avenue south of US-1. This will be one of the first avenues anywhere in Miami or Miami Beach to get real bike lanes, which is quite a mystery given the fantastic riding conditions year-round. Now bicyclists who ride transit will have dedicated lanes to get to and from Grove Station and the neighborhood’s business district.
  3. Traffic Circle: One of the most contentious aspects of the plan is the proposed traffic circle at 27th, Tigertail, and Day Ave. The county is proposing an irregularly shaped traffic circle for this intersection, which would allow for the removal of traffic lights. Predictably, Day Avenue residents were concerned that traffic would increase significantly on their street. However, the county is planning on changing Day Avenue from one-way westbound to one-way eastbound, meaning one cannot enter Day Avenue from the 27th Avenue traffic circle. This will be ensured by a continuous portion of curb that will jut out just enough to make the turning angle onto Day Ave from the the circle impossible without going over the curb. I like this idea, because it will force cars to slow down considerably at this awkward and dangerous intersection. It will eliminate the need to wait for red lights to cross, as well as also making pedestrian crossings shorter.
  4. On-Street Parking: It looks like 27th Avenue will finally get on-street parking. The county plans on implementing 90 on-street spaces along this segment of the avenue, which would look similar to the set-up on Grand Avenue. The plan would have called for more on-street parking, but it wasn’t possible due to the ridiculously large number of driveways on the avenue. These on-street spaces are of the “cut-out” variety, meaning no current capacity will be taken by parking as the spaces are “carved” out of the sidewalk.
  5. Right-of-Way-Acquisition: Perhaps my favorite part of the plan was the proposed elimination of many parking swales (or parking lagoons) that line the avenue on both sides. These swales equate to such bad urban design for so many reasons, hence my appreciation for their removal. For one, they are just ugly to look at. A high quality pedestrian environment is certainly not define by any space flanked by automobiles. Also, these spots are small, so often times cars are parked on segments of the sidewalk, forcing pedestrians to slalom the cars (sometimes requiring movement into the road) to traverse the swales. Also, this provides way too many free parking spaces along what should be a transit-oriented thoroughfare. As long as an abundance of free parking is available throughout the city, especially in close proximity to transit stations, induced automobile demand will remain high and transit ridership will not realize its ultimate potential. Moreover, these swales are just dangerous. They often require backing into the road, or other maneuvering within the swale that breaches the sidewalk. Lastly, these swales have always been located within the county’s right-of-way, and therefore people were parking for free within illegal zones. Therefore, the county is only retaking what is already theirs.
Those are the major portions of the project that were discussed at the meeting. Other factors such as landscaping and shade/sidewalk trees will certainly be implemented, but the specifics are still under consideration. So in conclusion, this project exceeded my expectations for the avenue. I’ll continued to post any updates on this project as I learn of them.

Odds N Ends

  • We took the time recently to check up on the Flagler Street Capital Improvement Project occurring in Downtown (Pictured Above, Look Valet Parking, so that you really don’t have to use transit) and were thus far dismayed by the progress. Aside from some “decorative” lamps, a few palm trees, and some bricks around the courthouse, the “Flagler Street Marketplace” as it is referred to on city records, is nothing but a lousy $12 Million makeover for one of our city’s principal streets.
  • Alesh, already spilled the beans on this one, but, the gears are in motion to bring streetcars to Miami (again.) They will traverse the city from the Stephen P. Clark Center North, just past the Midtown Miami Waste of Land Development and also head west through Overtown to the civic center area. Late by two years, this project is expected to begin construction next year and be fully operational by 2010. This streetcar system will provide residents with a great amount of mobility and will continue to spur development along its route and in the up and coming design and Wynwood districts.
  • Home owners in the Roads area of Miami are calling for traffic circles to be placed in their neighborhoods to help prevent a potential traffic disaster when all the new Brickell buildings are completed. The benefit of these devices abound keeping traffic under control yet flowing at a fairly constant rate. If only someone would design the things properly (omitting the hideous “Stay Right Signs” (Coral Gables), not encircling the thing with reflective French fry-like barriers (Miami/West Miami), Putting Yield signs instead of Stop signs (All of the above))…

Traffic Circles


A relatively new character appearing in many of our daily commutes in South Florida is the Traffic Circle. Today, we will discuss the advantages of such traffic calming devices and how their widespread implementation can be so useful.

The idea for this topic came about because of the many traffic circles already in use or under construction in the Coral Gables and the Roads neighborhoods. They serve many advantageous purposes and when placed in effective locations can provide some or all of the following benefits:

  • Shorter commute times
  • Improved Traffic flow through neighborhoods
  • Lower installation/operation/maintenance costs than typical stoplight intersections
  • Save fuel
  • Reduce accidents
  • Enhance and beautify communities
  • Improve pedestrian traffic

With fewer stop signs and traffic signals, commuters travel time is decreased significantly while also reducing the demanding fuel consumption of stop and go traffic flow patterns. They reduce accidents by forcing traffic to slow down to more manageable speeds and increase driver awareness. A study by the NTSB, found that traffic circles reduced all accidents at intersections by 39% and serious accidents by 79%.
