Indian River County Sector 3 Beach Restoration Project and Dune Repair Project
Post Construction Physical Monitoring Services - 2015
Dear James:
This proposal outlines a scope of work for CB&I Coastal Planning & Engineering, Inc. (CB&I), f/k/a Coastal
Planning & Engineering, Inc. to provide services in support of one year of annual physical monitoring to fulfill
FDEP and USACE permit requirements of the Sector 3 Beach and Dune Restoration Project constructed between
2010 and 2012 and the Sector 3 Dune Repair Project constructed 2014/2015. This proposal also includes a third
party peer review of the UMAM Analysis performed by CSA, and if necessary, quantification of hardbottom
impacts.
The 2015 Physical Monitoring Services entails the following:
• "Year 3" annual post construction physical monitoring of the Phase 2b project area (R-20 — R-26+500),
• Immediate post -construction physical monitoring for the Sector 3 Dune Repair Project Area (R-24 — R-
55).
Physical Monitoring Report
The Indian River County Sector 3 Beach Restoration Project and Dune Repair Project were constructed under
permitting authority of the Florida Department of Environmental Protection (FDEP) and United States Army
Corps of Engineers (USACE). These permits (FDEP permit No. 0285993 -001 -JC, FDEP permit modification No.
0285993 -008 -JN, USACE permit SAJ-2007-01645, and USACE permit modification SAJ-2007-01645(MOD-
AWP)) contain permit conditions pertaining to construction and post -construction periods. FDEP permit
condition 56 (d) requires an engineering report be submitted to the FDEP within 90 days following completion of
each post -construction survey.
We understand that Morgan & Eklund will perform the physical monitoring from R-30 to R-60, and be
responsible for certifying the survey data and submitting a survey report to the FDEP. Land & Sea Surveying
Concepts, Inc., via a separate contract with the Sebastian Inlet District, will perform the physical monitoring from
R-20 to R-30. They will certify the survey data and submit a separate survey report to the FDEP. CB&I will
review both data sets to ensure that it conforms to the standards required by the FDEP physical monitoring plan.
CB&I will notify the County of any issues with the survey data and will participate in a conference call with the
County, Morgan & Eklund, and Land & Sea Concepts to discuss any issues.
CB&I will develop an engineering report that discusses the performance of the beach fill project. We will analyze
shoreline and volumetric changes throughout the project area, identifying erosion and accretion patterns. The
results will be analyzed for patterns, trends or changes between annual surveys as well as cumulatively since
construction. The project was constructed in three phases and the analysis will account for the phased
construction. Furthermore, the report will compare the project performance to the stated design.
Plots of the survey profiles, and graphical representations of volumetric and shoreline positions for the monitoring
area will be presented. Summary tables of the shoreline and volumetric changes will be presented, again looking
at individual and cumulative shoreline and volumetric changes. Volumetric changes will be calculated above
+6.0 feet NAVD; MHW to +6.0 feet, NAVD; -5.0 feet, NAVD to MHW; and -12.0 feet to -5.0 feet, NAVD; and
landward of the approximate edge of hardbottom. The volumetric analysis will be performed similar to the 2014
report to avoid introducing error in the calculations due to the nearshore hardbottom.
CB&I will collect aerials of the project area as discussed more fully later in this scope of work. The aerials will
be collected from R-15 through R-60. Plots of hardbottom change and shoreline position will be overlaid on the
aerials and included in the report appendix.
The FDEP approved physical monitoring plan permit modification requires that sand samples be collected during
summer months coincident with the immediate post -construction monitoring event at four beach profile transects
(R-22, R-30, R-41 and R-52). Although sand was only placed between R-24 and R-55 during the Dune Repair
Project, all four transects will be sampled and analyzed for completeness and comparison with past data sets.
Five samples will be collected and analyzed along each transect (toe of dune, mid -berm, MHW, MLW, and -3
feet, NAVD) for a total of 20 samples analyzed. We understand that Morgan & Eklund will collect these samples
and ship them to us for analysis. CB&1 has a certified laboratory required by FDEP standards to analyze beach
samples. We will follow the FDEP protocols for sieving the samples using 20 sieves ranging in size from -4.25
phi to +4 phi at 1/2 phi intervals. A cumulative frequency distribution and frequency distribution histogram will be
presented along with a sediment analysis summary sheet providing descriptive statistics, compositional results,
percent fines and Munsell Color. The grain sizes will be compared to previous sediment samples to gauge any
changes in grain size or color.
Deliverables
CB&I will submit a draft of the report of the County for review and comment. This will be submitted
electronically (PDF and MS Word formats). CB&I will incorporate comments from the County and revise the
report accordingly. CB&I will then submit an electronic copy to the FDEP. CB&I will submit one hard copy and
one electronic copy (PDF) to the County.
Required Data
To perform the physical monitoring evaluation, CB&I will need the following data:
• Survey data in x,y,z format collected in summer of 2015.
• Sand samples collected in summer of 2015.
• Shape file or Auto CAD file of the landward edge of hardbottom mapped in summer of 2015.
Schedule
The draft monitoring report will be completed within 60 days of receipt of the survey data and sand samples from
Morgan & Eklund or the landward edge of hardbottom data from CSA International, whichever is later. We
estimate that the county will review and provide comments on the document within 2 weeks. CB&1 will revise
the report, incorporate the County's comments, and submit a final report to the County and FDEP within 2 weeks
of receipt of the County's comments. The goal is to submit the final report to the FDEP within 90 days of receipt
of the required data. Assuming that data is provided by August 31, we estimate submittal of a final report by
November 31, 2015.
Cost
The cost of the monitoring report, excluding the aerial collection is $35,057.00. A breakdown of the hours and
expenses to develop these costs is attached and follow the provisions of the Professional Coastal Engineering
Services Agreement (dated March 19, 2013) and Contract Renewal (dated March 17, 2015), between Indian River
County and CB&I.
Rectified Aerial Photographs
Aerial photographs are required per FDEP special permit condition 53 and 56(c) for the primary purpose of
mapping and quantifying exposed nearshore hardbottom and natural/artificial reefs. CB&I will have aerials
collected that follow BBCS Monitoring Standards for Beach Erosion Control Projects, Section 02100 —
Environmental Aerial Photography Acquisition.
Controlled, flight -dated, color vertical aerial photographs will be taken from Indian River County FDEP range
monuments R-15 through R-32, inclusive. Collection of the aerial photography will be timed so as to collect the
aerials concurrently with the post -construction surveys. CB&I will rely on Indian River County to notify us as to
when these surveys are being performed.
The flight will be conducted on an incoming tide and when there is sufficient visibility in coastal waters to capture
nearshore hardbottom. Film will be selected to provide the best possible images in the greatest possible water
depths. Photography will be obtained during morning hours with cloud cover at less than 10%, and in order to
minimize glint, the flight window shall occur when the sun angle is between 15 to 30 degrees to the horizon. If,
during the flight, weather conditions deteriorate to the point that the purposes of the flight can not be met, or the
five flight conditions are not satisfied, the flight will be aborted and flown at a later date when conditions are
satisfactory.
The photography will employ the use of a precision Zeiss RMK/A cartographic camera (or equal) calibrated by
the US Geological Survey. The camera will be equipped with a data block, which will record the lens number,
calibration, focal length of the lens, altitude, date, and time. The photographs will be color aerial photography and
georeferenced digital imagery with the following specifications:
1. A minimum 60% overlap with each adjacent photograph and a ratio of 50% land and 50% ocean (2000'
and 2000') on the horizontal.
2. The image will be clear and sharp in detail, free from clouds, shadows or any other blemishes that would
render the image as uncertain for mapping rock and reef features as far offshore as possible and no less
than -15 feet, NAVD.
3. Each frame will contain:
i. time of day clock in standard time,
ii. altimeter reading,
iii. exposure counter,
iv. camera identification number,
v. lens focal length in mm, and
vi. the plate ID number.
Necessary ground control will be extracted from existing imagery sources and used in combination with collected
ABGPS to rectify this imagery. It is assumed that previous control points can be used and have been previously
surveyed. No additional field work is included in this proposal.
Deliverables
CB&I will provide the following deliverables:
1. Two sets of color 9"x9" photography from R-15 to R-32 (one for the County and one for FDEP).
2. Camera Calibration report for camera used for this task contained on the CD-ROM.
3. Individual orthorectified frames of each project and reference in an uncompressed Geotiff format stored
on CD-ROM or DVD with associated world files.
4. JPEG of mosaicked images.
Required Data
CB&I may require additional survey points to rectify the images. We are proposing to sub -contract Aerial
Cartographics of America (ACA), who previously performed the work, and they should have sufficient historic
survey points to rectify the images. However, additional survey points may be required. Typically, the Public
Works Department will have surveys that can be used to rectify aerial images avoiding additional field work.
Schedule
We will attempt to time collection of the aerials to coincide with collection of the survey data. Final deliverables
related to the aerials will be submitted within 30 days of collection of the aerials.
Cost
The cost to collect the aerials and rectify the images is $15,805.00. A breakdown of the hours and expenses to
develop these costs is attached and follow the provisions of the Professional Coastal Engineering Services
Agreement (dated March 19, 2013) and Contract Renewal (dated March 17, 2015), between Indian River County
and CB&I.
Third Party Review of UMAM
We understand that Continental Shelf Associates (CSA) will be performing a Uniform Mitigation Assessment
Method (UMAM) evaluation for the Sector 3 Beach and Dune Restoration Project. The UMAM rule (Chapter
62-345, F.A.C.) went into effect on February 2, 2004 and is used by the FDEP to determine the amount of
mitigation needed to offset adverse impacts to wetlands and other surface waters and to determine mitigation bank
credits awarded and debited. A CB&I biologist will evaluate the UMAM analysis to ensure it was prepared in
accordance with FDEP guidelines and instructions contained in rule 62-345, F.A.C. CB&I will prepare a
summary of their findings from this review to be submitted to the County. CB&I will participate in a conference
call with the County and CSA to discuss any issues identified during our review.
Required Data
Electronic data (preferably GIS database) may be required to quantify changes in hardbottom area.
Schedule
Initial comments for the third party peer review of the UMAM analysis will be submitted within 2 weeks of
receipt of the analysis and report.
Cost
The cost of the third party peer review of the UMAM is $2,105. A breakdown of the hours and expenses to
develop these costs is attached and follow the provisions of the Professional Coastal Engineering Services
Agreement (dated March 19, 2013) and Contract Renewal (dated March 17, 2015), between Indian River County
and CB&I.
Summary
The total lump sum cost of this task order is $52,967.00.
We appreciate the opportunity to work with Indian River County on this effort.
Please call me if yo ave any questions.
