INTRODUCTION

The phenomenal growth of commercial, residential and recreational waterfront

developments in Florida has led to a rise in boat traffic, waterfront congestion, boating

accidents and wrecks. There are an estimated 3,000 dismantled, abandoned, junked,

wrecked, derelict vessels (DVs) in Florida coastal waters; 240 are situated in the Florida

Keys, where they pose an additional threat to delicate natural ecologies already affected

by increased water-related activities.

The State Department of Natural Resources (DNR), through its Florida Marine

Patrol (FMP), carries out a DV reporting program. This includes marking DVs by

painting an identification number on the hull and filing a DNR 20-012-FMP report. A

title search is included in the reporting process to determine DV ownership and

responsibility for removal. Vessel removal falls upon the shoulders of the DNR if the

owner cannot be located. Growth in the number of DVs has led the State of Florida to

establish a program for DV removal. This program is funded at $400,000 for fiscal year

1989. While most DVs are small recreation and fishing type vessels, limited resources

preclude removing all of them.

Some DVs impact the environment, people and navigation more than others.

Further, site conditions vary from place to place and make the removal process easy or

more difficult. As a result, the Florida Sea Grant (FSG) Extension Director, Monroe

County, requested assistance from the University of Florida (UF) in developing and

applying an indexing system to locate and prioritize derelict vessel removal based on (1)

actual impact or potential threat to people, the environment and navigation, and (2)

ease of removal. The Monroe County Commission has approved a Port Advisory









Committee recommendation to remove derelict vessels. The County's plan calls for a

phased approach. This report by the UF Cartographic Research Laboratory provides for

such a phased approach and is illustrative of FSG immediate response initiatives.
VESSEL INFORMATION

Derelict vessel reporting are concentrated in coastal areas subject to heavy

recreational and commercial uses. Correspondingly, the distribution of documented

DVs, in the case of the Florida Keys, is limited to the heavily trafficked Intracoastal

Waterway (ICW), Hawk Channel and adjoining harbors and estuaries. Other abandoned

or wrecked vessels situated along the Florida Reef, in the Marquesas and Dry Tortugas,

or in Florida Bay, for example, are not included in the FMP derelict vessel logs which

provide the basis of this report.

Data Structure

DNR 20-012/083-FMP reports are available for 240 DV cases in the Florida

Keys. Each report contains a description of the DV, its condition and location, effects

on environment and navigation, and removal characteristics. Additional information

includes color photographs, history of ownership, citations, and coastal chart with vessel

location. A sample form is in Appendix A. The data analyzed in this report are listed

in Appendix B. An outline of the data structure (Table 1) shows the 19 variables

classified as, general information (1-5), vessel characteristics (6-9), impact on locale (10-

13), and removal characteristics (14-19).

maps (Figures 5 & 6), interpreted from "x" marking DV location on coastal chart

accompanying FMP report. Ex., OBS 1, UF_ID (001), Appendix B.

2- Department of Natural Resources Identification Number: DV number painted

on vessel which appears on corresponding FMP report and attachments. Ex., OBS 1,

DNRID (9650), Appendix B.

3- Date: month, day, year when FMP report filed. Where several updated

versions cover a single DV, the most recent date is used. Table 2 indicates the

chronology of DV reports. Older (pre-1986) cases may be more difficult to locate; they

have been subjected longer to wind and water erosion and may be in a more

disintegrated state. The increase in DV cases over the last two years reflects more

vigorous FMP enforcement of DNR policy. Ex., OBS 1, MONTH (6) DAY (2) YEAR

(88), Appendix B.
4- Location: place name where DV is situated. The 240 DV cases are sited in 41

locations and Table 3 presents case tallies for each location. Place names appear on the

1:250,000, 1:5,000 and 1:12,000 scale maps (Figures 1-6). Highway U.S. 1 separates

bayside (Florida Bay) from oceanside (Hawk Channel) sites. Ex., OBS 1, LOCAT (16),

Appendix B, Conch Keys bayside (Table 3).

5- Homeport: reported as vessel owner's city of residence on the boat registration

verification portion of the FMP report. This is condensed into Lower (L), Middle (M),

Upper (U) Keys, and Other Areas (0). Ex., OBS 1, HOMEPORT (M), Appendix B.

Vessel Characteristics

6- Type of Vessel: interpreted from site photographs taken by FMP and described

as: P (power, recreation), S (sail), H (houseboat), B (barge), T (float), F (fishing).

Seventy-eight cases (33.0)1 cannot be determined and are reported as missing data. Ex.,

OBS 1, TYVES (H), Appendix B.

7- Hull Material: four types of hull material which characterize DVs are: F

(fiberglass), W (wood), S (steel), A (aluminum). Only 1 case is unreported. Ex., OBS 1,

HULLMATL (F), Appendix B.

8- Vessel Length: estimated by FMP inspection and reported in feet (ft.), ranging

from 10 to 108 ft. Ex., OBS 1, VESLENG (24), Appendix B.

9- Engine Onboard: estimated by FMP inspection, reported as Yes or No, and

whether inboard or outboard if Yes. Twenty-two cases (9.0), mostly submerged and/or

wrecked DVs, are unreported.

Impact on Locale

10- Potential Threat to Environment: reported as either Yes or No on the FMP

form, with an explanatory note, including possible impact on mangroves, bottom grasses,

and bay bottoms. In some cases, DVs possibly may contain fuel in tanks, either

completely or partially submerged, that may contaminate water and threaten marine life.

There is only 1 unreported case. Ex., OBS 1, ENTHREAT (N), Appendix B.

11- Potential Health Hazard: reported as either Yes or No on the FMP form,

with an explanatory note, including hazards to children playing on DVs, openings in

deck where people or children can fall through, and hazardous diving conditions. There

are isolated cases where hazards may result from DVs breaking free and drifting under

conditions of high winds and tides. There is only 1 unreported case. Ex., OBS 1,

H_HAZARD (Y), Appendix B.



1Figures in parenthesis are percentages unless stated otherwise.










12- Actual Obstruction or Potential Threat to Navigation: reported as either Yes

or-No on the FMP form, but must be qualified by perusal of coastal chart to determine

degree and nature of threat. Actual obstructions to navigation include blocking

navigable channels or obstructing access to docks. Potential threats include unlighted

DVs in congested basins and along narrow channel wideners. There is only 1 un-

reported case. Ex., OBS 1, NAVIGAT (N), Appendix B.

13- Actual Pollution: reported as Yes or No on the FMP form with explanatory

note, including predominantly, vessel-derived flotsam, and occasionally, fuel oil in water.

This is an actual condition, not a potential threat. There is only 1 unreported case. Ex.,

OBS 1, POLLUT (Y), Appendix B.

Removal Characteristics

14- Vessel Condition: description of DV status by FMP at time of last citation,

but must be qualified by perusal of photographs, reported as: I (intact), P (partially

broken-up), W (wrecked). Ex., OBS 1, VESLCOND (I), Appendix B.

15- Beached: reported for some cases as a vessel condition on the FMP report,

but based mainly on photo inspection, and adjusted to mean low water (mlw) conditions

(see Data Adjustments, below). Ex., OBS 1, BEACHED (N), Appendix B.

16- Afloat: reported for some DV cases as a vessel condition on the FMP report,

but based mainly on photo inspection and adjusted to mlw conditions. Any DV afloat is

considered not submerged (0.0), even though a portion of its hull may lie below the

water surface. An afloat DV presents less severe restrictions in salvage and removal

operations. Ex., OBS 1, AFLOAT (N), Appendix B.










17- Degree Submerged: reported as a percent of DV submerged, but qualified by

photo inspection and adjusted to mlw conditions. Cases range from 0.0 to 100.0 (all 0.0

submerged cases are considered either beached or afloat). Ex., OBS 1, SUBMERGE

(35), Appendix B.

18- Accessible by Sea: derived from depth of water (ft.) at DV site reported on

the FMP form, adjusted to mlw, and expressed as Yes or No, where No is less than 3 ft.

and is considered inaccessible because shallow water restricts salvage and removal

operations, and where Yes is equal to or greater than 3 ft. and considered accessible

because sufficient water depth is present to facilitate DV removal. Ex., OBS 1, DEPTH

(N), Appendix B.

19- Accessible by Land: derived by chart inspection of DV site in relation to road

access and expressed as Yes or No, where Yes signifies possible removal overland, and

No means that removal may be possible only by water. Ex., OBS 1, LAND_ACC (Y),

Appendix B.

Photographs 1-10 illustrate the types of DVs, their impact on locale and removal

characteristics.
DATA ADJUSTMENTS

Information pertaining to DV conditions and location are reported by FMP

officers using low, mid, or high tide conditions. Mean tidal range varies in the Florida

Keys from 0.0 ft. to 2.0 ft. Adjustment for inconsistencies in reporting procedures and

standardization to a common mean low water (mlw) datum is accomplished in this

report in the following manner.

1- Tide Tables are perused to determine the mean tidal range for central

locations in the Florida Keys (Table 4).

2- All FMP reporting using mid and high tide values are adjusted using mean

tidal range at cited locations (Table 4).

3- Water depth a surrogate for accessibility by sea (SEA_ACC), is adjusted for

case reporting (Table 5).

4- Tidal adjustments are made also for the degree submerged (Table 1, variable

17), where mid and high tide conditions are reported. Values are diminished

considering water depth and type of vessel. No change is made if degree submerged is

reported for low tide condition. Adjustments are critical where a case is recorded

completely submerged at mid or high tide, or where the DV is slightly more than half

submerged at mid or high tide. Under these conditions, the DV can be re-classified

from completely submerged (100.0), to less than completely submerged (50.0 to less than

100.0), or from less than completely submerged to partially submerged (greater than 1.0

to less than 50.0). These submerged nominal classes are used to determine degree of

removal difficulty.










17- Degree Submerged: reported as a percent of DV submerged, but qualified by

photo inspection and adjusted to mlw conditions. Cases range from 0.0 to 100.0 (all 0.0

submerged cases are considered either beached or afloat). Ex., OBS 1, SUBMERGE

(35), Appendix B.

18- Accessible by Sea: derived from depth of water (ft.) at DV site reported on

the FMP form, adjusted to mlw, and expressed as Yes or No, where No is less than 3 ft.

and is considered inaccessible because shallow water restricts salvage and removal

operations, and where Yes is equal to or greater than 3 ft. and considered accessible

because sufficient water depth is present to facilitate DV removal. Ex., OBS 1, DEPTH

(N), Appendix B.

access and expressed as Yes or No, where Yes signifies possible removal overland, and

No means that removal may be possible only by water. Ex., OBS 1, LAND_ACC (Y),

MAPPING PROCEDURES


Compilation

Project maps are compiled from U.S. Geological Survey (USGS) and National

Ocean Service (NOS) maps and aerial photographs. The regional (1:250,000) maps of

the Florida Keys (Figures 1-4) are compiled from USGS-NOS maps, Key West (1972)

and Miami (1988) and 7.5' quadrangles of the area. The Community Harbor map

(1:5,000) and Boot Key Harbor map (1:12,000) are compiled from enlargements of 1981

NOS color aerial photographs using a Zoom Transferscope.

Siting

Each DV is sited on the 1:250,000 maps using the "x" chart marked location on

the FMP report. Concentrations of DVs at Community Harbor, Holiday Isle bayside,

Boot Key Harbor, and Boca Chica Channel oceanside, require larger-scale field mapping

than is available from NOS charts. Large-scale DV sketch maps exists for Community

Harbor and Boot Key Harbor and are replotted on the photo-controlled 1:5,000 and

1:12,000 base maps (Figures 5 and 6).

Thematic Mapping

A proportional symbol distribution method is used to represent DV locations in

the Florida Keys (Figure 1). Individual DVs are represented by a single closed dot and

identified by a number (1-240). A proportional circle is used where multiple DVs are

situated close together and cannot be individually distinguished at the 1:250,000 scale.

In these cases, the radius of the circle is proportional to the number of DVs. A listing

of UF ID numbers is provided for each multiple case.








High, medium and low removal priority and removal difficulty classes for

individually distinguishable DV locations, are symbolized in Figures 2-6 as: high

(asterisk), medium (square), low (dot). The relative frequency of class values for DV

concentrations are shown by proportional circle diagrams.

VESSEL CHARACTERISTICS

Profile

Mean DV length is 27.9 ft. and 64.1 percent of all DVs are less than 30 ft. overall

(25.8 less than 20 ft., 38.3 between 20 and 30 ft.). Eighty percent of the DVs are fishing

type (54.3) and recreation power (25.3) vessels; the remainder consist of houseboat

(11.1), sail (5.6), float (2.5) and barge (1.2) types. Most are either wood (49.8) or

fiberglass (44.8) construction; steel (3.8) and aluminum (1.7) account for the remaining

fraction. Three-quarters of all reporting indicate no engine (inboard/outboard) aboard

(Table 6).

Location

The distribution of 240 DVs in the Florida Keys is shown in Figure 1 and listed

in Table 3. Upper Keys accounts for 86 (35.7), Middle Keys for 93 (38.8), and the

Lower Keys for 61 (25.4). A noteworthy characteristic is the clustered pattern: 3

locations, one in each of the above areas, account for 118 DVs (49.3). These concen-

trations, in descending order, are: 63 cases (26.3), Boot Key Harbor, Middle Keys; 34

cases (14.2), Community Harbor, Upper Keys; and 20 cases (8.3), Boca Chica Channel

oceanside, Lower Keys.

High, medium and low removal priority and removal difficulty classes for

individually distinguishable DV locations, are symbolized in Figures 2-6 as: high

(asterisk), medium (square), low (dot). The relative frequency of class values for DV

concentrations are shown by proportional circle diagrams.

VESSEL CHARACTERISTICS

Profile

Mean DV length is 27.9 ft. and 64.1 percent of all DVs are less than 30 ft. overall

(25.8 less than 20 ft., 38.3 between 20 and 30 ft.). Eighty percent of the DVs are fishing

type (54.3) and recreation power (25.3) vessels; the remainder consist of houseboat

(11.1), sail (5.6), float (2.5) and barge (1.2) types. Most are either wood (49.8) or

fiberglass (44.8) construction; steel (3.8) and aluminum (1.7) account for the remaining

fraction. Three-quarters of all reporting indicate no engine (inboard/outboard) aboard

(Table 6).

Impact

DVs may impact a site in 4 ways: potential threat to environment, potential

health hazard, actual obstruction or potential threat to navigation, and actual pollution.

Table 6 tallies the number of DV cases reporting impact by location in the Florida Keys.

There are 74 cases (31.0) of potential threat to the environment. The Lower

Keys leads with 39 (52.7) reporting and principal locations are Boca Chica Channel (18

cases) and Cow Key (7 cases). The Upper Keys accounts for 29 (39.2) reporting; these

include Community Harbor (14 cases) and Largo Sound (5 cases). The Middle Keys has

only 6 dispersed cases (8.1).

Potential health hazards are reported in 20 cases (8.4); half are in the Middle

Keys concentrated at Key Colony Coco Plum. The Lower Keys accounts for 9 cases

and there is a cluster at Big Pine Key bayside (4 cases).

Fifty-one cases (21.3) of actual or potential navigation hazards are reported for

DVs in the Florida Keys. The Upper Keys accounts for 21 cases (41.2) and Community

Harbor leads with 14 reporting. The Middle Keys has 16 cases (31.4) and Boot Key

Harbor accounts for 9 cases. The Lower Keys includes 14 cases (27.5) with a cluster at

Big Pine Key bayside (4 cases).

There are 55 cases (23.0) of actual pollution from DVs in the Florida Keys, 36 of

which (66.5) come from the Upper Keys, principally Community Harbor (9 cases), Key

Largo oceanside (7 cases), Largo Sound and Holiday Isle bayside (5 cases, each).

Another 13 cases (23.6) are found in the Lower Keys, principally at Cow Key (5 cases).

Summaries of these findings are tallied in Table 6 as number of vessel reporting.

These total 199, with 87 from Upper, 74 from Lower and 38 from Middle Keys

locations. The largest number of reporting by location are for Community Harbor (37),

Boca Chica Channel (24) and Cow Key (14). Vessel reporting include multiple threats

by a single DV as well as cases of solitary threats.

Removal

The ability to remove a derelict vessel depends upon its accessibility and

condition. Three accessibility types, unique to removal operations, are: accessible by

land, accessible by sea, and neither accessible by land nor by sea. Examples of these

respective situations are: a DV that can be removed using a bulldozer and truck, a DV

situated in water deep enough to permit barge and towboat operations, and a DV far

from land access and in water too shallow to permit barge and tow operations.

A derelict vessel in each accessibility type indicated above, may be found in one

of several conditions, as beached, afloat, partially submerged, less than completely sub-

merged, and fully submerged. Combinations of these two parameter sets are presented

in Tables 8, 9 and 10.

Table 8 tallies 37 DVs accessible by land, as beached, afloat, partially submerged,

less than completely submerged and completely submerged. These conditions, in most

instances, are mutually exclusive. There are, however, 4 cases of beached DVs that

register on the low end of the partially submerged class. UF_ID 159 at LOCAT 36

(Boca Chica Channel Oceanside) is an example.

Only 15 cases are beached and accessible by land. Half are in the Middle Keys.

Concentrations are at Marathon bayside (4 cases) and Grassy Key oceanside (2 cases).

Community Harbor, Upper Keys, has 2 beached DVs. There are only 5 afloat cases of

land accessible DVs and 4 are situated in the Big Pine Little Torch Keys area.

Six land accessible DV cases report partially submerged conditions and 5 are in

the Lower Keys, at Summerland Key bayside (2), Boca Chica Channel oceanside (2) and

at Little Torch Key bayside (1).

There are 11 cases of less than completely submerged DVs accessible by land and

the largest single concentration is at Community Harbor (5 cases); Boca Chica Channel,

Lower Keys has 2 cases. No completely submerged land accessible cases are reported.

Table 9 lists 77 DVs accessible by sea, in water depths 3 ft. or greater (mlw), as

afloat, partially submerged, less than completely submerged and completely submerged.

Overall case sums are 9 afloat, 18 partially submerged, 44 less than completely

submerged and 6 completely submerged. Note that 10 DV cases are accessible by land

and by sea (Tables 8 and 9, footnote). It can be assumed that the remainder (240

total 37 land accessible 77 sea accessible + 10 accessible by land and by sea) consists

of 136 shallow water cases situated in water less than 3 ft. deep (mlw). These shallow

water sited DVs include 18 beached, 13 afloat, 55 partially submerged, 46 less than

completely submerged and 4 completely submerged cases (Table 10). Concentrations

occur at Boot Key Harbor (48), Community Harbor (17) and Boca Chica Channel

oceanside (15).

PRIORITIZING SCHEME

Indexing

The principal objective of this study is to derive site ratings of removal priority

and removal difficulty for DVs in the Florida Keys. The ratings are based on numerical

indices, oftentimes referred to as parametric indices, which are computed from scores

assigned to vessel attributes related to environmental quality, navigation and access-









ibility. Numerical indices have been applied by scientists for many years but their utility

has become enhanced recently with the proliferation of computers, the development of

geographic information systems and the creation of geo-coded data bases (Riquier, 1974;

McRae and Burnham, 1981; Burrough, 1986; Davidson, 1986). These indices, however,

have not been applied, heretofore, to vessel siting and classification.

Standard site evaluation methodology is applied in the computation of the

indices: identification of vessel characteristics relevant to environmental quality and

vessel removal procedures, classification of ranges of values of vessel characteristics,

selection of a model for index computation, definition of scores to be assigned to classes,

computation of index values, conversion of numerical index values to nominal ratings,

cartography of ratings. The computations and conversion to nominal ratings were

performed on the University of Florida mainframe computer using the Statistical

Analysis System (SAS, 1983).

Removal Priority Index

The Removal Priority Index, R, is derived from four impact variables listed above

in Table 1.

Impact Variable Number in Table 1

Potential threat to environment 10

Potential health hazard 11

Actual obstruction or potential threat to navigation 12

Actual pollution 13

Index values are computed from scores which were related on the basis of

consultation with the Monroe County Sea Grant Extension Director. The scores are

related to the relative importance of each impact variable. The index value ranges from









1.0 which represents maximum priority for removal to 0.0 which symbolizes the lowest

priority. The algorithm for index computation is described as follows:

If d = 1, then R = 1,

elseR=a + b + c

where:

R = removal priority index

a = potential threat to environment

b = potential health hazard

c = obstruction to navigation

d = actual water pollution



The appropriate scoring system is:

Variable Yes No

Potential threat to
environment 0.4 0.0

Potential health hazard 0.4 0.0

Obstruction to navigation 0.2 0.0

Actual water pollution 1.0 0.0

The values of R are converted into nominal removal priority ratings (high,

medium, low) as follows:

Score Rating

1.0 High
0.8 High

0.6 Medium
0.4 Medium

0.2 Low
0.0 Low









The number of cases reported for each strata in the three nominal priority ratings

are listed in Table 11.

Removal Difficulty Index

The five characteristics considered for the removal difficulty index are:

Removal Characteristics Number in Table 1

Beached 15

Afloat 16

Degree submerged 17

Accessible by sea 18

Accessible by land 19

On the basis of information provided by the Monroe County Sea Grant Extension

Director, 14 scenarios were defined and ranked in decreasing order of removal difficulty

as illustrated in Table 12. The scenarios were subsequently classified into 3 nominal

classes of removal difficulty. The class of low removal difficulty consists of DVs with the

land access. Vessels in the moderate class are only accessible by sea. The high removal

difficulty class is composed of vessels with neither land nor sea access.

Each scenario was assigned a specific value of removal difficulty index D. The

value of this index ranges from 1.00 which represents maximum difficulty of removal to

0.00 which symbolizes least difficulty. The numerical index values were selected for

future refinements of methodology. A salvaging company might be prepared to face the

cost of derelict vessel retrieval if it has relatively high scrap value. Consequently, the

numerical value of index D could be decreased by an appropriate amount for such

vessels. This simple cost/benefit adjustment might, in some cases, lead to re-

classification of the derelict vessel into a more favorable nominal priority class e.g. from

Results
Removal priority ratings (high, medium, low) are listed for each location in Table

13 and plotted for each DV in Figure 2. DVs rated high priority, having the greatest

impact or threat to people and the environment, are concentrated at Key Largo (9 at

Community Harbor, 7 at Key Largo oceanside). DVs rated medium priority are

clustered at Boca Chica Channel (15) and also at Community Harbor (9). The largest

low priority rated DV concentrations are at Boot Key Harbor (61), Community Harbor

(16), Key Largo oceanside (7), and Marathon bayside (9).
Removal difficulty ratings (high, medium, low) are listed in Table 14 for each

location. The map in Figure 3 identifies removal difficulty for each DV. Over half

(56.7) of all DVs rate a high score. The pattern is fairly evenly distributed over the

Upper (32.4), Middle (41.9) and Lower (25.7) Keys. Most DVs in the Key Largo area

(17 at Community Harbor, 10 at Key Largo oceanside) and those at Boca Chica (15) in

the Lower Keys rate high difficulty of removal. Most DVs in Boot Key Harbor (48 out

of 63) rate high removal difficulty but their removal priority ratings are low.

Community Harbor, with 34 derelict vessels and 37 reported vessel impacts on

environment, health, navigation and pollution, is the worst case scenario in the Florida

Keys. A site assessment is mapped at large-scale (1:5,000) in Figure 5. DVs ring the

harbor: greatest concentrations are along the mangrove western shore and adjacent to

Campbell's Marina in the southeast (Map A). Over one-half are medium to high

removal priority vessels (Map B): 25 percent are actual polluters and 38 percent pose

environmental and navigation hazards. Community Harbor presents a dilemma since 50

percent of the DVs are rated high and 29 percent are medium in removal difficulty; only

7 DVs (21) are easy to remove. Map C shows the locations of vessels characterized by

low removal difficulty adjacent to Campbell's Marina and clustered in an embayment in

the mangroves on the south coast. Map D focuses on the 9 high priority DVs and

classifies their difficulty of removal.

Boot Key Harbor, with 63 derelict vessels, has the largest concentration of all

sites in the Florida Keys. Figure 6 maps this site assessment at large-scale (1:12,000).

DVs are situated in the inner, eastern harbor near the old Colpac Fisheries docks, in the

mangroves adjoining the canal leading to Becher Marine, and on Boot Key's north shore

on both sides of the bascule bridge. There are fewer DVs in the outer western harbor

(Map A). Sixty-one vessels are typed low removal priority since they have limited

impact on the environment, health and navigation (Map B). However, many of these

are a visual blight on the seascape, particularly in the inner harbor. They are used

periodically as shelters by street people. Most DVs are either moderate to high removal

difficulty (Map C).









CONCLUSIONS

The site indexing method, application and results provide a basis for developing a

two-step approach to derelict vessel removal in the Florida Keys.

Step 1 priorities DV removal based on impact or threat to people and the

environment. Four parameters are scaled with maximum value assigned to actual water

pollution, intermediate value to health hazard and environmental threat, and least value

to obstruction to navigation. The combined score of the four parameter set represents

the removal priority index value (R) for each DV, which is converted into high, medium,

low nominal ratings.

Results of Step 1 analysis indicate:

1- 128 DVs (53.3) rate a low priority; these may be eliminated from further

consideration.

2- 53 cases (22.1) rate medium priority; these may be considered for removal at a

later date.

3- 59 cases (24.6) are top priority rated and should be the focus of immediate

efforts to clean up the environment and reduce hazards to people and navigation.

An important consideration in any vessel removal program is the determination

of ease or difficulty of removal. The removal difficulty index uses 5 parameters related

to accessibility and degree of submergence to scale high, medium and low difficulty.

The removal difficulty index is a rough surrogate for removal cost: low difficulty equates

with low cost and high difficulty with high cost.

Results of Step 2 analysis provide a means for narrowing down the process of

removal selection. Roughly half of the 59 top priority cases are rated low to moderate

in removal difficulty. The other half are difficult to remove (Table 15). Budget

restrictions may limit removal to a relatively small number. Selecting DVs from the low

to moderate end of the removal difficulty scale may increase the number of DVs that

can be removed, thus widening the scale of removal operations and maximizing the

impact.

Table 16 lists the high removal priority vessels by difficulty class and by location.

The map in Figure 4 plots the 59 DV high priority cases. This information provides for

additional planning options, namely, ability to focus removal operations on specific areas

where high priority DV concentrations are situated, such as Key Largo, or to selectively

target individual DVs at various, specific locations.

RECOMMENDATIONS

This report summarizes an initial test of a DV siting and removal rating scheme.

There are a number of improvements that should be made in future applications.

1- Redundancies in answers to questions on the FMP form, e.g., actual pollution,

threat to environment, health hazard, can be eliminated by providing FMP officers with

answer keys.

2- Questions on beached, afloat, water depth and degree of submergence should

be answered using a standard datum, mlw.

3- DV siting can be made more precise, especially at locations where DV

concentrations are found, by using large-scale aerial photographs to fix vessel location.

Latitude-longitude reckoning, in degrees, minutes and seconds with provision for

recording tenths and hundredths of seconds, should be adopted so that DNR reports can

be linked to the NOS Automated Wreck and Obstruction Information System (AWOIS).

The latter system provides a basis for updating the nation's hydrographic charts. There

is no link between NOS and DNR systems at present, and, as a result, valuable DV

RECOMMENDATIONS

This report summarizes an initial test of a DV siting and removal rating scheme.

There are a number of improvements that should be made in future applications.

1- Redundancies in answers to questions on the FMP form, e.g., actual pollution,

threat to environment, health hazard, can be eliminated by providing FMP officers with

answer keys.

2- Questions on beached, afloat, water depth and degree of submergence should

3- DV siting can be made more precise, especially at locations where DV

concentrations are found, by using large-scale aerial photographs to fix vessel location.

Latitude-longitude reckoning, in degrees, minutes and seconds with provision for

recording tenths and hundredths of seconds, should be adopted so that DNR reports can

be linked to the NOS Automated Wreck and Obstruction Information System (AWOIS).

The latter system provides a basis for updating the nation's hydrographic charts. There

is no link between NOS and DNR systems at present, and, as a result, valuable DV









information on obstructions to navigation in Florida waters is unavailable for chart

correcting purposes.

4- Information on vessel characteristics can be made more precise in determining

removal costs. Condition criteria should be standardized: intact, partially broken-up,

wrecked, or similar descriptive terms, should be explicitly defined in the report and not

left solely to photo inspection. Type of vessel and vessel specifications (length, beam,

draft) should be included to aid in estimating gross tonnage. Bulk, weight and condition

of DV are key elements in estimating removal cost.

5- A question should be added to the FMP form to determine DV impact on the

visual seascape. Maintenance of scenic beauty, important in recreation destination areas

and nature preserves, can be seriously blighted by DVs without their contributing to

actual water pollution or threatening the environment. We surmise this is the case at

Boot Key Harbor where the largest DV concentration is situated in close proximity to a

wildlife sanctuary, residential and boating communities.

6- Form revisions, as recommended above, should be pretested at various

locations to assure proper coverage of local conditions throughout Florida.

7- Adoption of standardized reporting procedures statewide by FMP personnel

can be facilitated by in-service training using the FSG extension program.

8- The removal difficulty index could be developed into a cost of removal index

but this will require additional information from other sources, as salvagers, waste

collectors, municipal and county public works departments. Costs will vary statewide

because of local conditions. Disposal problems, unique to the Florida Keys, as limited

landfill, shallow water restrictions, and land access restrictions along Highway U.S. 1, are









examples. Statewide applications of a cost removal index should reflect such regional

disparities.

9- Finally, DVs are situated in a dynamically changing environment subject to the

natural forces of coastal erosion and deposition. Storm occurrence may dramatically

affect the DV inventory of a given area by removing some vessels and creating others.

A DV siting program should be an ongoing process where periodic updating of the

inventory incorporates changes in condition and location of existing DVs, addition of

new wrecks and deletion of those eliminated by removal operations. Such a planned

approach can aid in safeguarding Florida's unique coastal habitat.
