Our staff has perforr.ed a biological survey for this project and offers
the fol 1 awi ng corments :
The applicant proYoses to construct a 632-ft. long by 47-ft. wide
bridge over Saddlebunch No. 2 Channel. The existing bridge is to
remain in place. rpproacite, at thle Key t,cst and : iami cnd. will be
lengthened and widened and a shoulder will be created along the
north side (Gulf side) of C.Q.S. 1. This shoulder construction will
necessitate filling of subrerc7ed and transition zone areas. Submerged
lands total 47,0.91 cubic yards while transition zone areas total
13,399 cubic yards raking a grand total of 61,3590 cubic yards.
Depending on the alternatives, an additional 10,050 cubic yards
All be te:::;orarily placed on sub. forced lairds or 15,t"0U cubic yards
gill a -)a reroved fron sub:rerc�d lands. To reduce pilirg breakage,
36-inch diar.,eter holes All i:e pre drilled. An estirated 86 cubic
yards will be unrecoverable from the drilling operation.
The general area around Saddlebunch Bridge A2 is undeveloped with
only marginal disturbance to adjacent transition zones and "upland"
areas. South and test of the .existing Sa ddlek unch ? Erid ce is an
area which has been developed into a canal subdivision with subsequent
dredging and filling. north and east of the proposed bridge is
another canal subdivision wthich has experienced sfi:dlar developrent.
The botto;ls substrates are norrally bard except in disturbed areas
or depressions where rarl sedirents and ornanic debris have accurulated.
The "upland" arras located slightly above the mean hick wrater
elevation are vecoetated prir iaril_v by red r: anrroves. 6pland vegetation
along disturbed areps consists of red, black and r.hite ri;angroves
and buttonwood. Su€ n-,ergent veftetation in time -eneral area co:,sists
of marine algae and sea grasses.

The specific worksite is located immediately north of the existing
Saddlebunch #2 Bridge. Both approaches, Key West end and t-iiani
end, are vegetated by a mixture of red, white and black mangrove
along with buttonwrood and halophytic succulents.
On undisturbed submerged bottoms, the substrate is generally solid,
composed of limestone with a thin layer of marl overlay. In the
disturbed area parallel and adjacent to the existing bridge, the
substrate varies only slightly. Mediuri-fine to fine marl particles
mixed with unconsolidated organic debris have drifted into the
excavated area and have filled it nearly to the existing surrounding
contour. The original depth of the excavated area ranged from 3
feet below the bottom substrate to 5 feet. Water depth in the
Urnediate area was no deeper than 2 feet and closer to 1 foot near
the existing bridge.
Vegetation located in the project area is low in diversity but lush
in grovith. Turtlegrass is the predominant grass growing in the
previously disturbed area adjacent to the bridge. Cuban shoalweed
was also noted in this area rtiore specifically along the entire
southern edce of the disturbed area. This growth was extrerely
dense. Sparsely scattered through the grass were several species
of macroscopic algae. farine algae are found along all the piling
and fill areas adjacent to both skies of the existing bridge.
Turtlegrass and several species of r:iarine algae are located beneath
the existinu triage primarily in depressions containing water 6
inches to 1; inches deep.
The width of the disturbed section distinctly seen as the vegetated
grassy area is approxiiately 10,g feet wide. This area, of course,
parallels the existing bridge. Located to the south of
the existing bridge is fill which extends south nearly 50 feet from
the bridge supports. This rwaterial wras probably placed in this
location during the construction of the existing bridge. Peter
depth is very shallow and several areas exhibit small accu-i_-:ulations
of concrete rubble. ' There appears to be a very minir,al floe through
the spanned opening.,
A variety of marine life was observed around and under the bridge
as well as in the grass flats: sponges, tunicates, coral and other
coelenterates, gastropods, spiny lobster, rays, grunt, snapper,
parrot fish, small r?arine. tropicals and numerous macro -invertebrates,
including various shrimp, crams, polychaetes and amphipods.
Alternate "A" entails dredging in an area approxir.iately 632 feet
long by 160 feet wide by -5 feet in depth. This will result in
approximately 15,000 cubic; yards being removed from the dredge
area. Alternate "E" entails te:nporary fillin:� 10,0E0 cubic yards
adjacent to the existing bridge along the north side.

Both of these proposals are objectionable. Alternate "A" will
disrupt approximately 101,120 square feet of submerged bottom. The
bottom discontinuity which will result from the excavation is
expected to entrap organic matter adversely effecting Prater duality
and under surge conditions possibly resuspending such unconsolidated
particles. From the information contained in the application, no
provisions are rade for restoration after the bridge is Completed.
The excavation itself will elinlnate the entire vecetative corclunity
which has re-established itself in the previously disturbed area.
This excavation will also resuspend all flocculent particles which
have settled and were stabilized by the vegetation cover. Vegetation
has been shown to stabilize substrates, increase the dissolved
oxygen to surrounding water, increase nutrient recycling, and
provide attachment and habitat for benthic organisms which are an
excellent food source for higher organisms.
The dredge alternate lacks data addressing the methodology of
dredging in an area of frequently exposed lirierock substrate (i.e.
blasting).
Alternate "8" proposes to temporarily fill 10,050 cubic yards
adjacent to the existing bridge. Alternate "€3" will eliminate the
sarpe vegetated area that Alternate "A" v.ill eliminate by direct
filling. This condition is only temporary since the fill will be
rcraoved down to the original contour. !-loviever, it is my opinion
that none of the vegetation will re -main after placing and then
rer:.oving the fill. Removing the vegetation will result in the same
problems encountered in Alternate "A". Ono other probl en to contend
With is that an unstable substrate will be allowed to interact with
state grater providing the possibility of siltation and degradation
of iwater quality. the fill alternative lacks essential information
addressing slope stabilization-Aethods to control erosion and wash-
out, and duration estinlates pertinent to flooding and seasonal tide
variances pertaining to the temporary fill area, necessary hfdrographic
data is also r:issing (i.e. volu-:� of flow, velocity of floor, etc.).
Specific data of this nature is essential to understanding the head
differential and tidal variables likely to result in relation to
the culvert sizing and frequency.
Another riajor probleri is the filling to the north of U.S. 1 from
just test of Saddlebrtnch #5 to east of Sugarloaf Channel. The
place:r:,ent of over 300,000 cubic yards of F1'aterial vaill eliminate
natural transition and submerged vegetation over a 3.3 vile length.
Additionally, over 260,000 cubic yards of fill will be needed for
this area alone to bring the project area up to specifications
along the 'shoulder area"/realign ent of U.S. 1 which extends from
S,addlebunch 4,5 to Lower Sugarloaf Channel. The source of such
large mounts of fill, VIhich has yet to be determined, may create
future environrental problews.

The tower Sugarloaf and Saddlebunch Keys areas should be considered
environmentally significant as an essential link in the marine food
chain. This hiqhly sensitive mangrove ecosystem, characterized by
relatively shallow tidal waters, is utilized extensively as nursery
and feeding grounds for juvenile fish and wildlife. The tidal flow
at the subject bridged interfaces allows an essential exchange of
nutrients and migratory larva. Elevated voluries of flow at these
Say/Straits interfaces were produced by the original roadway construction
diverting the diurnal flooding and draining of vast areas. Alterations
to the tidal flow of such a shallow area would not only affect
nutrient exchange and migratory fauna patterns, but could expose
vast areas of habitat not adapted to such stress.
Examples of the integrity of the bridge construction and maintenance
methods utilized in the past are evidenced by the random deposit of
structural concrete members and rubble into the craters directly
below. The subject applications involve extensive alterations to a
vast, significant and sensitive ecosystem. Pre -application planning
meetings stressed the idea of coordinating the fill requirements
(approximately 30-60,000 cubic yards per bridge) in this area of
minimal uplands with coiwmunity needs (i.e. potential marina sites)
so as to incur the maximum future use of these necessarily large
borro4r sites. Since proposed construction techniques will elimI nate
a large area of valuable transition zone and submerged land habitat,
it is tern,.-zlended that the project be modified to eliminate the
proposed shift nortliv.,ard of C.S. 1 which extends into the transition
.zone and submerged land areas.
Pursuant to the requirer-t;ent of Section 253.124(3), Florida Statutes, the
preceding corsients should be duly considered by the cor ission and read
into the iiinutes at which determination of local approval is r-:ade.
Sincerely,
