satisfied:
1 . The street sign bollards;
2 . light fixtures;
3 . paver blocks; and,
4 . irrigation.
Some of the Board Members felt that there were not enough
canopy trees and the consensus was that this would be
discussed at the next meeting and the consensus of the
Board would be forwarded to Nancy Davila.
Sandy Jamison moved for approval to recommend to the City
Commission that they move forward with the Swinton Avenue
Beautification Plans, seconded by Pat Healy-Golembe. The
vote was as follows : Christine Bull - Yes; Daniel Carter -
Yes; Sandy Jamison - Yes; Pat Healy-Golembe - Yes; Buck
Miller - Yes; Margie Miller - Yes; Rose Sloan - Yes. Said
motion passed 7-0.
The Board also felt that the street lights and pavers at
intersections should not stop at N.E. 4th Street, but
should be carried to the end of the Historic District at
N.E. 8th Street, to do so more money would have to be
allocated by the City Commission. The Board's comments
will be stated at the City Commission Worksession scheduled
for July 6, 1993 . Nancy Davila encouraged a representative
of the Board to attend the worksession. The Board will
discuss this matter further at their June 16, 1993 meeting.

SUBJECT: HPB MEETING JUNE 2, 1993, AGENDA ITEM V. SWINTON
AVENUE BEAUTIFICATION
Nancy Davila has requested this meeting as a follow up to
the workshop meeting of May 19, 1993. The purpose is to
address some of the concerns expressed by the HPB during the
• discussion which occurred at the end of the HPB' s Regular
Meeting. A narrative, prepared by Grant Thornborough, is
attached which will explain some of the decisions and
. recommendations that were made by the Swinton Avenue Task
Team. The Swinton Avenue plans are available in Nancy
Davila ' s office if you wish to consult them for reference.
The Swinton Avenue Task Team members have been invited to
the meeting.
The City Commission Swinton Avenue Workshop meeting has been
postponed until July 6, 1993.
SWINTON AVENUE BEAUTIFICATION PLAN EXECUTIVE SUMMARY
The beautification of Swinton Avenue is a unique challenge because all of the
landscape must occur in swale areas in front of hundreds of individual properties. Most
beautification projects and streetscapes which have been successful have either
occurred in median areas or in swales under common ownership or the collective
control of master property associations. A. Grant Thornbrough and Associates feels
the following items must be done to accomplish the beautification of Swinton:
increase greenspace, reduce pavement, reduce parking in the swale, eliminate
unsightly utilities, repair walkways and driveways, landscape the swales with trees,
palms, shrubbery and sod, irrigate the swales, add decorative elements such as lights,
pavers, and signage, encourage community and property owner organizations to
heighten beautification awareness, long term maintenance, revise garbage pick up,
and revise delivery and postal service practices. Some of these items are not feasible
due to budgetary constraints . Others represent policy changes and educational
changes that need to occur. Most items can be implemented to some degree which is
what we have accomplished with our preliminary plans.
The objective of the Swinton Avenue beautification project is to emphasize street trees
and swale improvements, accent gateway focal points, and provide hardscape
elements such as signage, street lights, pavers and selective curb and gutter while
adhering to maintenance, safety and budget considerations ($ 450,000).
The scope of the project is divided into three priority areas:
Priority area 1- From S. 2nd to N. 8th which is the concentration of the historic
districts
Priority Area 2- From S. 10th Street to S. 2nd Street
Priority Area 3- From N. 8th Street to N. 22nd Street
1
In priority area one, the main objectives are to accent and identify the historic
district, and to improve the swales and landscape profile while keeping a residential
character. As there is an increase of commercial properties in this area, we are
proposing several elements that would compliment the Atlantic Avenue and Old
School Square Improvement projects and tie into the existing character. These
elements include lighting, pavers, and coconut palms as well as groundcover where
the project is suffiently irrigated. Identity of these areas would be accomplished with
signage depicting the different historic districts.
In priority area two the main objectives are to create a gateway and anchor at the
South end of the project, identify parking and drainage problems occurring in the
Right-of -way, and enhance the landscape. The anchor at the south end is developed
through Pioneer Park. We propose that this area be irrigated and landscaped to
screen the railroad tracks and provide a passive greenspace. In this priority area we
have been cautious to locate landscape nodes where irrigation is existing or will occur
either by the city or multi-family commercial properties through code enforcement. We
also have located nodes where parking problems can be minimized in identified
problem areas.
In priority area three, we have designed the landscape to enhance the existing
profile and kept it congruent with the proposed improvements in the previous areas.
The Swinton beautification plans use specific elements to link all three priority areas..
One of the hardscape elements is a street signage program that would be unique to Swinton Avenue. This street signage would consist of a decorative colored
concrete bollard that would bear the name of the street using a reflective material. The
task team has discussed painting the numbers or letters on the sign, but felt this would
create a maintenance headache for the city. We have recommended using the
standard metal sign with a blue background that would be fixed to the concrete
bollard. This sign would be clear, reflective and not require painting.
Through landscaping , we have also repeated plant material throughout the project,
2
clustered Saba! Palms in curbed landscape knuckles, various shade trees and
groupings of accent and flowering trees. The sabal palm was chosen for several
reasons as the street tree in the landscape knuckles: its hardiness, its vertical nature
to add interest to the horizontal plane, low maintenance, and, as a point of interest , it
is the state tree. Another positive note on the sabal palm is that we can plant the palm
so as to not interfere with the overhead power lines which are typically on one side of
the street and in some blocks on both sides.
An original objective established by the task force was to design a landscape that
would be diverse in species. This informal approach reflects the essence of
Swinton Avenue which makes it unique. We have surveyed existing trees and have
filled in voids along the swale with either shade trees or smaller accent trees. It is our
position that a regimented rhythm of treescape must be avoided.
Irrigating the proposed planting is one of the biggest issues that needs to be faced.
To irrigate the entire swale would take approximately 1/2 of the construction budget,
as well as require the city to come up with funds for the cost of water and perpetual
maintenance of irrigation system. Our recommendation for the irrigation constraints
are as follows:
Priority Area 1- The city to install a system and irrigate from S. 2nd to N. 4th. This
would enable more intense planting in this area that would help unify Swinton Avenue
to Atlantic Avenue and Old School Square.
Priority Area 2- The city to install a system and irrigate the Pioneer Park greenspace.
Large multi-family projects on the east side of Swinton are required to supply an
irrigation system to the swale adjacent to their properties. There is also existing
irrigation in a large pocket S. of S. 4th Street, at the Water Treatment Plant / Seimans
Evert and across the street at Griffin Gate Housing. However, on the west side of the
street we would need to rely upon the single family homeowners to take pride and
leadership in the project and irrigate the swale.
3
Priority Area 3- We are not planning on irrigating in this area and again are relying on
the homeowners support to irrigate the swale. Several property owners from the
north end have stated they will cooperate with the irrigation because of the aesthetic
and economic improvements they will receive from the improvements
If the entire swale is not irrigated, then a program of regular watering for 6 months will
be necessary to ensure the survivability of the plant material. Although the water
truck is a large expense, other solutions of watering have not been economically
feasible.
Whereas drainage is a problem along some parts of Swinton Avenue, it was in the
project objectives to identify these areas and to not create any other problems as a
result of our design. It is not in the scope of services nor in the budget to curb and
gutter the entire length of Swinton as this would require millions of dollars in a new
drainage system. We have taken into account these drainage problems and for this
reason have come up with the following solutions:
1.) Regrade the right of way to create a swale. Remove the old curb that could interfere
with drainage flow, and improve soil conditions for increased percolation where soil
has been compacted.
2.) Remove excess asphalt in areas that do not belong in the right of way and replace
with sod to improve percolation and in turn beautify the profile of the Avenue.
Reduction of the asphalt in areas where it is not part of the traffic flow will improve the
scale of the street and give it a more of a residential flavor.
3.) Create a depressed area behind the curbed landscape knuckles to collect runoff
around the planted areas. These curbed knuckles will also protect the plant materials
behind them, prevent parking in areas where this is a problem, and will enable us to
get the plant material closer to the road and away from overhead utility lines.
The majority of site features are occurring between S. 2nd and N. 4th. Pavers on all
4
four corners and Period street lights are used as a way of tying back this historic district
to the Atlantic Avenue Improvements and the Old School Square Project. Preliminary
plans did show lights and pavers from S. 2nd to N. 8th as well as pavers in the
crosswalks at the downtown bypasses, but due to budget constraints the task team
decided that this area between S. 2nd and N. 4th would be the best place to
concentrate these elements in order to make a difference. Several street lights were
proposed including concrete, aluminum, and fiberglass, all with a decorative acorn
lamp. After a task force discussion, it was determined that the project would use an
aluminum pole to coordinate efforts with other lighting programs already established
by the CRA and to match the existing lights at Old School Square and along Atlantic
Avenue. The use of a concrete pole would be more historically correct for the city.
The task team also wanted to address and improve the downtown bypasses. The
bypass N. of Atlantic is paved from right of way to right of way which leaves us no room
for planting. The paving in this area is all travel lanes making it impossible at this time
to manipulate. We will encourage future development in this block to add lighting and
landscaping on their own property congruent to the Swinton Avenue Beautification
Project. However, the bypass S. of Atlantic has potential to be reconfigured in order to
accomodate landscape islands on both sides of the street. Preliminary cost estimates
showed that pursuing a reconfiguring of the bypass lanes S. of Atlantic would be
approximately 1/4 of the budget. The task team felt it would be a considerable amount
of money for such a limited area although it would be a much needed improvement.
After this discussion of the cost factor in this area, the city encouraged us to investigate
our options and it was determined that we could improve the southern bypass for
approximately $85,000.00. This would entail reducing the expanse of asphalt, and
providing 6' landscape strips on both sides of the street for approximately 1 1/2 blocks.
This option does not change any traffic patterns, only the lane locations. We have kept
this improvement option as a separate line item in the cost estimate.
Another item we have kept separate from our cost estimate is the landscaping and
irrigation of Pioneer Park, the anchor for the project at the South end. This area is
not within the right of way of Swinton Avenue, but as a project goal we were asked to
investigate options for this greenspace. We have designed a passive greenspace that
5
would screen the railroad tracts and provide a natural gateway into the project.
The plans do not address sidewalk improvements other than the addition of pavers at
historic district intersections.
The condition of the driveway aprons along the street varies from nonexistent to brand
new. We conducted a visual assessment of the aprons and determined that 55 new
ones are required for a greatly enhanced aesthetic appearance.
