Staff Contact /Phone #: Rhonda Haag, 453-8774
AUF-INDA ITEM WORDING: Approval of Amendment No. 1 to the Task Order with AMEC Environmental
& Infrastructure, Inc. to perform bathymetric surveys and collect and analyze soil samples. This Amendment
No. 1 will slightly reduce the number of canals being surveyed and reduce the funding accordingly by $49.66
per each 1/10 mile of canals not surveyed. The estimated reduction in contract amount shall be approximately
$3,000 for canals not surveyed. The final list of canals not able to be surveyed within the time period of the
Agreement will be included in the final deliverable product by June 14, 2013.
ITEM BACKGROUND: AMEC was to perform bathymetric surveys on 502 Keys Canals and sediment
collections on 10 canals. However, inclement weather and canal access issues have slowed the progress of the
work. Not all of the 502 canals will be able to be surveyed within the project time period. This Amendment
allows for a cost reduction of the final list of canals not able to be surveyed by AMEC. Ten sediment samples
will still be collected and analyzed. The $100,000 not to exceed amount will remain, but payment will be
reduced by the number of canals that are not surveyed. This Amendment has been agreed to by DEP, the
grantor. The matching DEP amendment is submitted separately on this June 20, 2013 BOCC agenda.
PREVIOUS RELEVANT BOCC ACTION: On March 21, 2012 the BOCC granted approval and authorized
execution of Item 6 Grant Agreement from FDEP for a Grant to fund Phase 1. On June 20, 2012, the BOCC
approved the grant application submitted to EPA, which requested $100,000 in grant funds and specified a
$10,000 match of in -kind services. On September 19, 2012, the BOCC approved the revenue -producing grant
agreement from EPA that funded Task Order #2 with AMEC. The DEP revenue -producing grant agreement for
the bathymetric surveys was approved February 20, 2013. The AMEC contract for performing the bathymetric
surveys was also approved February 20, 2013.
%Aviv iKAUJUTAUKEEMEINT CHANGES: The scope of work identified as "A-l" has been modified to allow

FOR ON CALL PROFESSIONAL ENGINEERING SERVICES
BETWEEN
MONROE COUNTY
AND
AMEC ENVIRONMENT $ INFRASTRUCTURE, INC.
FOR
BATHYMETRIC SURVEYS AND ORGANICS CHARACTERIZATION
IN THE MONROE COUNTY CANALS
This AMENDMENT NO. 1 is entered into on this 191' day of June. 2013 to the Task Order S0640 between
Monroe County hereinafter referred to as the °County" and AMEC Environment & Infrastructure, Inc.,
hereinafter referred to as "Consultant".
WITNESSETH THAT
WHEREAS, AMEC has been diligently performing work under the Task Order, and
WHEREAS, Inclement weather has delayed the surveys being performed by staff on survey boats; and
WHEREAS, canal access has been limited to some canals, causing difficulty with access and slowing the
work; and
WHEREAS, AMEC has advised that a reduction in the scope of work is necessary as not all work can be
completed by the termination date.
NOW THEREFORE,
The "Scope of Basic Service" Is hereby deleted in its entirety and replaced with the following:
"Scope of Basic Services Al is as follows:
The scope of work is for performing bathymetric surveys to determine the average depths of all of the
residential canals (total of 502 canals) Identified In the 2003 and updated in 2012 Monroe County
Residential Canal Inventory & Assessment. However, due to access and weather issues, all of the 502
canals may not be able to be surveyed within the time period of the Agreement. AMEC will complete as
many canals as possible and will provide a list of canals not surveyed, including an estimated number
of miles in each non -surveyed canal, with the final deliverable. A cost reduction will be applied based
upon the non -surveyed miles of canals at the rate of $49.66, which shall be deducted from each 1/10''
mile of canal not surveyed under Task 1.3.
The surveys will be performed using automated hydrographic survey equipment consisting of a dual
frequency echo sounder used in conjunction with a GPS positioning system to survey a profile of each
canal centerline with bottom surface elevations of the canal, relative to the North American Vertical
Datum of 1988 (NAVD88), determined at approximate 50' intervals and at the end and mouths of the
canals. As part of this effort AMEC will obtain, through the use of the automated hydrographic survey
equipment and traditional probing methodologies, sufficient data to provide approximate information
regarding unconsolidated material thickness within the canals.
Ten (10) sediment samples will be collected and will be submitted for physical and chemical
characterization to assist in refining the design for removal and disposal of the material from the canal
bottoms. The samples will be collected from 10 different canals based upon a preliminary evaluation
from the GIS database, aerial photo review and public communications of the canals where seaweed
Page 1
loading is a serious problem. The sample locations will be based upon confirmed presence of a
significant organic layer in that portion of the canal.
Details of the scope of services are included in Attachment A-1."
The Consultant shall be paid monthly with the not to exceed fees shown in Attachment A-1, which
shall not exceed $100,000 and as follows:
Task 1.1: Completion of Bathymetric Survey of 30% of the Canals $25,324.62
Task 1.2: Completion of Bathymetric Survey of an Additional 30% of the Canals $25,324.62
Task 1.3: Completion of Bathymetric Survey for Remaining 40% of Canals and Final Reporting $33,766.161
Task 2.0: Sediment Characterization and Reporting $15,584.60
Total NTE Fee $100,000.00
' If all of the canals under Task 1.3 (201) are not surveyed, then $49.66 shall be deducted from the total
Task 1.3 budget per each 1/10 mile of canal that is not surveyed. The reduction is estimated to be $3,000 for
canals not surveyed.

Project Backgr
ound:
The work to be accomplished under this Agreement is one of the high priority projects identified during the
development of the Phase I of the Canal Management Master PIan (CMMP).
Bathymetric surveys will be performed to determine the depths of all of the canals identified in the Geographic
Information System (GIS) database developed by AMEC (formerly MACTEC Engineering and Consulting, Inc.) in
2001-2003 as part of the Monroe County Residential Canal Inventory and Assessment, to determine the approximate
thickness of unconsolidated material lying in the bottom of the canals and to collect samples of the unconsolidated
materials. The length of the canals identified in the GIS was initially 111 miles with an additional six (6) miles
delineated during the recent aerial photo update performed in 2012 (total of 117 miles of canals). The survey will
not include [marinas or turning basins. The canal depth data in the existing GIS database is based upon limited
permit information and not actual depth measurements. The depth of the canals and the approximate thickness of
unconsolidated materials in the canals are critical factors in evaluating potential restoration needs and in quantifying
restoration costs.
The purpose of this project is to determine the depth of the canals identified in the GIS database developed by
AMEC (formerly MACTEC Engineering and Consulting, Inc.) in 2001-2003, as well as the approximate thickness
and physiochemical composition of the unconsolidated sediments found in the bottom of these canals. This
information is required in order to accurately determine the costs of implementing the canal restoration strategies
developed during Phase I of the CMMP in DEP Agreement No. S0607. Many of the canals in the Florida Keys
National Marine Sanctuary (FKNMS) do not meet the State's minimum water quality criteria and are a potential
source of nutrients and other contaminants to near shore waters designated as Outstanding Florida Waters and
subject to special protection under the Florida Statutes. This project is a priority of the FKNMS Water Quality
Protection Program (WQPP) Steering Committee which recently passed a motion to develop a plan to prioritize
canal restoration projects and to identify funding sources for these projects. The tourism economy of the Keys
depends largely on clean water and a healthy environment and this project is fully supported by the WQPP Steering
Committee and local governments in Monroe County. The successful implementation of this project is also
consistent with the goals of the Florida Keys Reasonable Assurance Document that was recently adopted by the
Department in order to satisfy the requirements of the Impaired Waters Rule, Chapter 62-303 of the Florida
Administrative Code.

Project Description:
Task 1: BATnymETRIC SURVEYS OF RESIDENTIAL CANALS
The Grantee will perform bathymetric surveys to determine the average depths of all of the residential canals (total
of 502 canals) identified in the 2003 and updated in 2012 Monroe County Residential Canal Inventory &
Assessment (refer to Table 1 for a list of the canals). The surveys will be performed using automated hydrographic
survey equipment consisting of a dual frequency echo sounder used in conjunction with a UPS positioning system to
survey a profile of each canal centerline with bottom surface elevations of the canal, relative to the North American
Vertical Datum of 1988 (NAVD88), determined at approximate 50' intervals and at the end and mouths of the
canals. An elevation will be collected of the natural sea bottom at the canal mouth. The collected survey data will
be referenced to the North American Datum of 1983 AD83 to allow for inclusion into the existing GIS. As part
Page 3
of this effort the Grantee will obtain, through the use of the automated hydrograph is survey equipment and
traditional probing methodologies, sufficient data to provide approximate information regarding unconsolidated
material thickness within the canals.
The bathymetric data collection will be divided into 3 tasks as follows:
Task 1.1: Completion of Bathymetric Survey for 151 of the Canals
Bathymetric surveys as detailed above will completed for 151 of the 502 canals in the Monroe County Residential
Canal Inventory and Assessment GIS data base (refer to Table 1).
Deliverables: A CD with a subset of the GIS canal layer and a Google Earth Pro layer for the 151 canals which
were surveyed with updated attributes of depth and organic thickness, and an excel file of the updated attributes of
depth and organic thickness. All surveying and mapping services associated with this assignment will conform with
the requirements of the Department's Bureau of Survey and Mapping, and applicable sections of Florida
Administrative Rule Chapter 57-17, Minimum Technical Standards, pursuant to Chapter 472, Florida Statutes.
Budget: $25,324.62 for subcontractor
Performance Measure: The Department's Grant Manager will review the deliverables and will consult with the
appropriate staff of the Department's Bureau of Survey and Mapping to verify the deliverables conform with the
criteria found in 5117, F.A.C., pursuant to Chapter 472, F.S. .

Task 13: Completion of Bathymetric Survey for Remaining 201 of the Canals and Final Report
Bathymetric surveys as detailed above will completed for the remaining 201 canals of the total of 502 canals in the
Monroe County Residential Canal Inventory and Assessment GIS data base (refer to Table 1). In the event that all
of the remaining 201 canals cannot be surveyed within the time period of this Agreement, a list of canals not
surveyed will be provided including the estimated number of miles in each uosurveyed canal. The measurements
will be derived using GIS and aerial photos of the centerlines of all canals (including all fingers) to the tenth of a
mile. Compensation for the reduced scope will be reflected in a unit price reduction in the task budget based upon
the following formula:
Total Task 1 cost to complete the entire canal bathymetric survey ($94,415.40) divided by the total number of miles
in all Keys canals (170 miles). This equates to a cost of $ 49.66 per 1/10 of a mile of canal.
Page 4
The total number of miles of canals in the entire Keys is measured using GIS and aerial photos of the centerlines of
all canals (including all fingers) to the tenth of a mile of the 502 numbered canal systems in the GIS database (Table
1).
Deliverables: The final deliverable products will include a technical memorandum which summarizes the work
completed under Task 1. The technical memorandum will include the following attachments: a certified Surveyor's
Report of the survey operation and results, a CD with a complete GIS canal layer and a Google Earth Pro layer for

the total Task 1.3 budget.
Performance Measure, The Department's Grant Manager will review the deliverables and will consult with the
appropriate staff of the Department's Bureau of Survey and Mapping to verify the deliverables conform with the
criteria found in SJ-17, F.A.C., pursuant to Chapter 472, F.S. .
Completion Date: June 14, 2013 '
NOTE: Payment will be upon completion of the task and review and approval of the deliverables.
Task 2: SEDIMENT cEuu mRIZATION AND REPORTING
Ten (10) sediment samples will be collected and will be submitted for physical and chemical characterization to
assist in refining the design for removal and disposal of the material from the canal bottoms. The samples will be
collected from 10 different canals based upon a preliminary evaluation from the GIS database, aerial photo review

reimbursement.
Completion Date: June 7, 2013
NOTE: Payment will be upon completion of the task and review and approval of the deliverables.
Task 2: SEDIMENT CHARACTERIZATION AND REPORTING
Ten (10) sediment samples will be collected and will be submitted for physical and chemical characterization to
assist in refining the design for removal and disposal of the material from the canal bottoms. The samples will be
collected from 10 different canals based upon a preliminary evaluation from the GIS database, aerial photo review
and public communications of the canals where seaweed loading is a serious problem. The sample locations will be
based upon confirmed presence of a significant organic layer in that portion of the canal.
The physical testing will be performed by an AMEC Geotechnical Lab and will consist of the following:
- Moisture/Solids Content by ASTM D-2216
- 200 Mesh Sieve Distribution by ASTM D-1140
- Organic Content by ASTM D-2974
- Specific Gravity by ASTM D-2974
- Grain size distribution by ASTM D-422 (4 samples only)
- Settling rate (2 samples only)
The chemical characterization to determine disposal options will be performed by Test America Analytical
Laboratories, a State National Environmental Laboratory Accreditation Conference (NELAC) certified laboratory.
The proposed test methods include:
- Organochlorine Pesticides and PCBs by 8081/8082
- Chlorinated Herbicides by 8151
- 8 RCRA Metals by 6010/7471
- Copper by 6010
- Polynuclear Aromatic Hydrocarbons (PAHs) by 8270 low level
- Total Recoverable Petroleum Hydrocarbons (TRPH) by FL -PRO
- TCLP metals (2 tests only based upon total metal's concentrations)
Deliverable: A technical memorandum containing the above referenced test results and summary of sediment
disposal options that will meet all applicable Department regulations, including the requirements of Chapter 62-160
of the Florida Administrative Code.
Budget: $15,584.60 for subcontractor
DEP Agreement S0640, Attachment A, Page 3 of 12

Department's Standards and Assessment Section and the Division of Waste Management staff to determine if they
are acceptable using the following criteria:
1. The sampling and test procedures must be conducted in accordance with the requirements of Chapter 62-
160 of the Florida Administrative Code.
2. The sediment disposal options provided in the technical memorandum must be consistent with all
applicable Departments' regulations.
Financial Consequences: Failure to meet the above performance measure will result in rejection of the request for
