Mayor Meserve called the meeting to order at 7:15 p.m. "1' a invocation given
by Commissioner Parsons was followed by the Pledge of Allegiance to the Flag.
1. Approval of tlic minutes of the FOP Impasse Hearing of November
3, and t}ie Regular Commission Meeting of November 10, 2003
Motion: Approve the minutes of the Impasse Hearing of November
3, and the Regular Commission Mectinb of November 4, 2003 as
presented.
The motion carried unanimously.
2. Courtesy of the Floor to Visitors
Curtis Sanders of 2320 Barefoot Trace expressed concern for citizen safety
and encouraged the Commission to clear the underbrush on the lot located at
Atlantic Boulevard and Aquatic Gardens. Ile also requested that the
Commission revisit the ordinance regulating the use and length of time a POD
maybe placed on site. He indicated a POD was being used as a construction
trailer in Oceanwalk and had been on site for more than six weeks. He felt this
was an improper use of a POD.
Alan Potter of 374 Second Street spoke in support of Resolution 03-17 (Item
6A). Mr. Potter felt a new statewide authority would just be another
unregulated taxing authority that provided little help to the citizens.
Stephen Kuti 1132 Linkside Drive stated he opposed construction of a
roundabout (Item 8B) at the 5-way stop since there would not be enough space
for cars to merge into a roundabout from Sherry Drive.
Jane Wytska of 352 Second Street complained of the noise, dirt, dust in the
air, overflowing dumpsters and blocked traffic associated with the construction
occurring at 328 Second Street. Ms. Wytska felt it was unfair to the residents
who live in the area to have to endure these conditions.

J.P. Marcliioli, 414 Sherry Drive commented on the following: (1) The street
being replaced at 374 Second Street did not appear to have a limerock base, (2)
The use of millage to generate revenue for the city was more equitable than
using revenue from increased water/sewer rates, (3) He personally used the 10°i
Street Beach Access because it was the most available, (4) It was unfair for the
St. Johns River Water Management District to direct the city to target wasteful,
unnecessary, and inefficient water users, (5) Opposed the construction of a
roundabout at the S-way stop, and (6) Favored the use of POD's for
emergencies, but otherwise felt they should be regulated.
3. Unfinished Business from Previous Meetings
A. City Manaber's Follow-up Report
City Hall Expansion Cost Estimates
City Manager Hanson reported that Jose Perez, the city's architect for the
project, estimated that it would cost $5,000 for additional architectural services
to provide an estimated construction cost for constructing the new addition to
support a second story.
Tree Lighting Ceremony
City Manager Hanson reported that the December 6, 2003, Tree Lighting
Ceremony would be held at 6:00 p.m., not 6:30 p.m. as listed in his memo.
B. Report and Possible Action Rebardmg Speed Bumps on Plaza
Director Thompson reported that the traffic study on the 300 block of Plaza was
based on a speed limit of 25 MPH while the actual speed limit in that block is
20 MPH. A re-evaluation of the data from the study indicated a significant
speeding problem, and Dir. Thompson recommended that the speed bumps
removed during Core City construction project be replaced.
Public Works Director Kosoy provided drawings showing the location of the
proposed speed "humps" and stated that they were 22' long, 3.5" high and
tapered down at driveways
Discussion ensued and Commissioner Beaver inquired if the residents had been
notified. Public Works Director Kosoy indicated that they had not yet been
notified. Commissioner Simmons inquired if the "humps" would cause
problems for bicycle riders. Public Works Director Kosoy felt they would not
cause problems since they were only 3.5" high.
Commissioner Waters said he was opposed to the "humps" and stated he did not
think there was a speeding problem, and inquired why Plaza was chosen for
speed bumps over other heavily used streets, such as Sherry or East Coast
Drive.
Commissioner Simmons felt the city should be consistent and have an overall
plan or several plans, which differentiate types of streets, to justify installation
of speed "humps".

• Commissioner Parsons stated he was not in favor of speed bumps and suggested
the city consider other types of traffic calming devices before installing the
"humps".
Mayor Meserve stated that the city had a policy in place relative to requests for
speed bumps, and since the speed bumps were there before the Core City
project, he supported replacing them.
Commissioner Waters stated that he would like more information concerning
speeding, and the number and location of accidents, excluding Mayport Road
and Atlantic Boulevard.
Motion: Defer action until the first meeting in January to allow
Chief Thompson sufficient time to come back with additional data
and other options for traffic calminb.
Following brief discussion, the motion carried by a three to two vote with
Commissioners Parsons, Simmons and Waters voting aye and Commissioner
Beaver and Mayor Meserve voting nay.
4. Consent Agenda:
Commissioner Beaver requested that Consent Agenda Item 4B be removed

B. Award Annual Contract in tlic amount of $47,906.25 to A
Native Sun Landscaping for Landscape Maintenance for
Public Works and Public Utilities pursuant to the
Specifications of Bid No. 0404-5 (City Manager)
Commissioner Beaver inquired concerning the previous year's budget for
landscape maintenance.
Utility Director Kaluzniak stated that the budget of $46,000 was less than
last year because the lift stations were taken out of the bid specifications
and would be maintained by city personnel.
Commissioner Beaver noted the large price difference between the lowest
and next lowest bidder, and inquired if the company's references had been
checked.
• Utility Director Kaluzniak stated that the references were checked. She
indicated that the city would monitor the work of a Native Sun and if they

Motion: Authorize the Mayor to execute an agreement,
with Oceanside Rotary Club, for fundraising iu
connection with a proposed Skate Park at Russell Park.
(The Commissioners agreed to amend Page 2 of the agreement to
reflect that upon delivery of the funds in full, the park will be
named Oceanside Rotary Skate Park).
Carolyn Ettlinger, President-Elect of the Oceanside Rotary Club,
distributed information relative the club's fund raising of $50,000 for use
in the design and construction of the skate park. Ms. Ettlinger requested
that the agreement be amended to include on Page 2, that the skate park
will be named "Oceanside Rotary Skate Park". There were no objections
to the request.
It was reported that Commissioner Waters had donated $300.00 and Rotary
International had issued a check for $4,700 for the park as part of the 100°i
Anniversary Celebration of Rotary in February 2004.
The motion carried unanimously.
B. Report from Bob Kosoy on Roundabout Design for Seminole
Road 5-Way Intersection
Public Works Director Kosoy reported that two engineering firms, both
familiar with the Core City Project, were contacted concerning the
feasibility of constructing a roundabout at the five-way intersection. Both
of the companies provided reports to the city indicating a roundabout could
be constructed there. The reports are attached and made part of this
official record as Attachment A. Public Works Director Kosoy further
reported that the engineering firms both recommended a Roundabout
Justification Study.
Mayor Meserve stated that a roundabout would have a significant impact
on the intersection but the city needed to consider public safety. He felt

that if the city was going to consider a roundabout, a study should be
completed.
Motion: Authorize staff to proceed with the Roundabout
Justification Study.
Commissioner Waters said he understood the problems with the
intersection, but he felt there was enough right-of--way to build the
roundabout.
Commissioner Beaver thought a roundabout would be aesthetically
pleasing, but thought there were safety concerns with six unevenly spaced
entry points into the roundabout in such a small area. He felt the study
would give the city a definitive answer regarding the feasibility of
constructing a roundabout.
The motion carried unanimously.

CITY OF ATLANTIC BE NOVI?:ll3E1Z 24 , 2003 COIv1MISSION rtEETING
CITY COMMISSION MEETING
STAFF REPORT
AGENDA ITEM: Roundabout at Five-Way Intersection
SUBMITTED BY: Robert S. Kosoy, P.E.
Director of Public Works
DATE: November 14, 2003
BACKGROUND:
Since the late 1990's, there have been discussions about the construction of a roundabout at the
five-way intersection of Plaza, Seminole and Sherry Drive. Staff prepared snaps in 1999 demonstrating
four configurations where a large truck would have conflicts with a 60' diameter roundabout.
Recently, we contacted two engineering firms familiar with the Core City improvements Project and
asked their traffic engineers to provide a brief report. Both Paul Vetter, P.E. from Edwards and Kelcey
(formerly Aikenhead & Odom) and Fraser Howe, P.E. from GAI Consultants were very gracious in
.providing the attached reports to the City, at no cost. Both reports indicate difficulties with the site:
the proximity of the driveways, the need to shift the linear path of Sherry Drive to Seminole Road
going north, and the five-legs to a proposed roundabout. Both engineers feel that a fire truck could be
accommodated by redoing or relocating the driveway and constructing the outer portion (approximately
8-10') of the roundabout in concrete curb and brick pavers that could be driven upon by a fire truck, as
necessary. Both firms suggested that a program called "Autoturn" could be used to simulate these
movements by a fire truck very effectively.
The next step would be to complete a Roundabout Justification Study. This step would compare the
operation of a roundabout to the current controls, i.e. stop signs, and estimate the average delay for
vehicles using the intersection. After this step, the traffic engineer will recommend how a roundabout
would affect the safety of the intersection.
Although both firms could capably handle the project, we feel that based on the initial submittal, GAI's
recent experience designing roundabouts in Florida, and their involvement with the Core City Project,
that they would be able to minimize costs and provide an innovative design.
RECOMMENDATION: Authorize staff to negotiate with GAI Consultants to complete a
Roundabout Justification Study, and, if justified, furnish a preliminary
design and cost estimate, for a cost Not to Exceed S 10,000..
BUDGET: Commission to authorize from General Fund.

AGENDA ITEA1 #8B
NOVEMBER 24, 2003
I have reviewed the plans presented to me by Bob ICosoy on October 31, 2003 showing
the concept design for a roundabout at the subject location. The undated 1"=30 scale
plans displayed a roundabout at the subject five-legged intersection with an inscribed
(outside circle) diameter of ] 00 feet, a central island diameter of 60 feet and various
islands channcIizing traffic. I have reviewed these plans and offer the following
comments:
•

re ~ f/~dC/~ cvr~/al /Yro/e ih
1. The five two-way legs create too many approach roadways to the roundabout aa~d
too many closely-spaced conflicts within the smallest roundabout recommended
by the Federal Highway Administration in their published "Roundabouts: An
Informational Guide". The fire station driveway, although low volume, adds to
the complexity with a sixth Ieg.
2. The lnforrr-ational Guide (supported by our experience in roundabout design)
recommends all approaches to the roundabout align to the center point of the
roundabout to reduce the speed on the approach, ephasize the yield condition,
create a proper sight angle and align the roadways for good positions entering and
exiting the roundabout. The subject roundabout has two approaches (Sherry
Drive and the westbound approach of Plaza) wherein the approach aligns straight
into the circular roadway and thus encourages higher speeds and disregard for the
yield condition on the approach; the straight through movement on both of these
approaches has no curve alignment to it. These two approaches could be curved
at the roundabout and aligned at the.center of the roundabout; however, with the
small radius of the roundabout there is insufficient room for the five approach
roadways. Holding the outside edge of the roundabout at the fire station driveway
and enlarging the roundabout to the northeast may provide enough length around
the roundabout to fit the five approach roadways. This would require additional
tight of way.
3. The best solution to retain the roundabout would be to relocate Seminole Road to
intersect Sherry Drive approximately 180 feet from the centerline of Plaza and
cluninate the approach to the roundabout. The roundabout should then be moved
to be centered on the intersection of the centerlines of Sherry Drive/SeminoIe
Road North and Plaza and redesigned with four approaches. The alternative
would provide the best condition and location for the roundabout but would
require right of way and property acquisition.
4. A further study should be conducted for the roundabout to include a
traffic/capacity analysis using aaSIDRA software and a concept design
investigation of the alternatives, includin :Sight of way acquisition.

Subjeck: PROPOSED ROUNDABOUT AT SEMINOLE RD/PIAZPJSFIE.RRY qR, ATLANTIC BEACH
Dato: 11/612003
I have reviewed the sketches from Bob Kosoy, City Director of Public Works, for the
subject intersection. I referred to the Florida Roundabout Guide (FRG), 2"J Edition
(FDOT, 5/98); and Roundabouts: An Informational Gulde (RIG), FHWA-RD-00-067.
these are the references we used to design the roundabout for the City of Kissimmee's
MLK Blvd project. Please refer to the hand-drawn sketches attached to the hard copy of
this memo.
The geometry shown on the City's
sketches generally conforms to the FDOT
& FHWA guides, using a 60-foot diameter
central island and 20-foot wide circulating
roadway for asingle-lane roundabout. A
few of the entry and exit canes seem
narrow, but could be modified.
Approach Apparent FRG Min
Width Width
_ _
NB Seminole Road __
10' ..
19'
NB Sherry Dr 10' 19'
WB Plaza exit 12' 16'
The major problem that I see with the layout is that the islands will not divert the path of
vehicles going from NB Sherry Dr to NI3 Seminole Rd; nor for those going west on Plaza
across the roundabout. To operate safely, the geometry of a roundabout must work to
slow down entering vehicles to a speed close that of vehicles circulating around the
central island. This allows entering vehicles to merge into gaps between those already in
the roundabout; and allows vehicles exiting the roundabout to weave across entering
traffic. This assumes that drivers obey the basic principle to yield to vehicles in the
roundabout.
The splitter islands on each approach force the driver to divert to the right at the yield
line and the position of the central island forces the .driver to circulate with traffic. The
same thing happens to drivers exiting the roundabout ~ they must maneuver around the
central island, then around a fairly tight radius (30-foot min) to depart. I have sketched in
a few changes in the geometry to create diversions on the Sherry Dr and Plaza
approaches.that may help this situation.
This effort to slow-down vehicles (to about 20 - 30 MPH) also helps pedestrians
crossing the approach roadways. Note that the recommended. geometry places the
splitter islands across the crosswalks to glue pedestrians a refuge to cross only one
direction of traffic at a time. This is a second problem with the conceptual layout -the
splitter islands between Sherry pr and Seminole Rd are nGt in line with the obvious
pedestrian paths to cross those streets, i.e, people will probably cross before reaching
the islands.

The last issue 1 see is with several driveways that either enter directly into the
roundabout or onto the approaches, very close to the roundabout. I understand that the
one info the roundabout is for a fire station; however 1 see 2 other drives entering
Seminole just south of the intersection. Could the fire station use these? Also,.the drive
for #870 Seminole Rd is really too close to the roundabout. Could they share a drive with
#888 Seminole Rd or shift their drive to Plaza, west of the intersection?
I am most interested in supporting the City of Atlantic Beach to design in intersection
improvement here. The next step would be to do a Roundabout Just~ication Study, as
described in the FDOT Manual of Uniform Traffic Studies (MUTS), Form 750-020-18.
We would need the following information:
1. An accurate topographic survey (in CAD) of the intersection and approach
roadways.
2. 24-hour approach counts, peak-hour turning .movement counts and
pedestrian/bicycle counts, and transit routes.
3. location of adjacent signalized intersections (to avoid causing problems there).
4. Location of nearby traffic generators and special uses (school, hospital, sports or
entertainment facility).
The justification procedure will compare the operation of the roundabout to stop-sign and
traffic signal controls and estimate the average delay for vehicles using the intersection.
If the City can provide us with all of the data listed above, i estimate that we could
complete the report within about 32 hours of staff time. Please let know how you want to
proceed.

only on suee[s with approadt speeds of 55 km/h (35 mphj or 12ss, as the inU'oduc-

6.3.6 splitter islands
•
•
Splltter islands (also caged separator islandsor median islands} should be provided
on all raund~bouts, except those with very small diameters at which the splitter
Island would obstruct tha visibility of the central iSland,Their purpose is to provide
shelter ror pedestrians (including wheelchairs, bicycles, and baby strollCrs), assist
in controlling speeds, guide traffic into the roundabout, physically separate enter-
ing tandexiting Ctattic streams, slid deter wrong•way movements. Additionaly, splitter
islands cmi be used as a place for mounting signs (see Chapter 7},
1
1'he splitter Island envelope is formed by the entry and exit curves on a leg, as
shown previously in Exhibits 6.2a and 6-25. The total length of the (shed should
generally be at leas[ 75 m (b0 fQ to provido sufficien[protection For pedestrians and
to alert approaching drivers to the roundabout geomeuy. Additionally, the splitter
island should extend beyond the end of the exit curve to present exiting traffic from
accidentally crossing into the path of approaching traffic.
Exhibit G•26 shows the rctirtimum dimensions for a splitter island at a single-
laneroundabout, including tl~e location of the pedestrian crossing as disctisseU
in Section 6.3.7.
