Reference: Indian River County Beach Preservation Plan 2019 Update-
Scope/Fee Proposal
Mr..Gray,
Stantec Consulting Services Inc. is pleased to provide professional consulting and coastal
engineering services to support Indian River County by performing an update to the
County's Beach Preservation Plan (BPP) for 2019, which was originally produced in 1988,
with subsequent updates in 1998, 2002, 2008, and 2015. The BPP is the principal document
utilized to evaluate and maintain the resources along the coastline under the County's
Coastal Restoration Program (Program). This proposal outlines the scope of work for
Stantec to complete the 2019 update on behalf of Indian River County.
BPP Update Report Intent and Layout
The purpose of the 2019 update to the BPP is to support the County in managing its
beaches, analyze recent storm events, assess risk along the coast, and document the
overall program performance. The report will discuss resiliency elements that include
discussions regarding beach management strategies, coastal vulnerability, seasonality of
the beach sediments and provide new ideas on beach profile designs to promote natural
recovery.
This update to the BPP will be developed to provide a more comprehensive summary then
the previous update. The report will be written in a manner intended for multiple audiences
and the general public consumption. The main body of the report will be prepared with
this consideration. Any items that are more technical in nature, analyses completed, or
background data will be referenced in an appendix.
Scope of Work
Task 1: Beach Conditions Update
Stantec will analyze shoreline and volumetric change conditions based on the latest
available survey data from the County. The 2015 BPP analyzed shoreline and volumetric
changes for time periods (1972 to 1986, 1986 to 2005, and 2002 to 2013).This analysis will be
extended through to 2019 to include the winter 2019 and summer 2019 survey data, if
available. The depth of closure will be evaluated on a line by line (FDEP R-monument
beach profile) basis before developing an average depth of closure. The impact of
W (< 1 / :.

hardbottom on the depth of closure will be discussed.The erosion analysis shall include all
survey data from 2005 to the most recent data available, and report shoreline change (at
0 ft,5 ft,and 10 ft elevation) and volumetric change (to an agreed upon depth).The report
will include a tabular and graphic (bar graphs similar to previous BPP updates) presentation
of the data for each R-monument in the County. Background erosion rates will be reported
for each sector in shoreline and volume change rates per year.
Stantec will also evaluate the impact of the recent hurricane events (from 2013 to 2018).
We will examine recovery of the beach with respect to the shoreline and various dune
elevations to determine whether natural recovery can be expected under future storm
events and to what extent. Stantec will document any recent beach restoration projects
from 2013 through 2019, if completed with available data. Stantec will also analyze
seasonality through recent survey data collected by the County during the summer/winter
time periods.
Task 2: Meetings/BCC Updates
Following completion of the draft BPP update, Stantec will present to the IRC advisory
committee to explain the goals and objectives of update and to gain input from
stakeholders,as deemed necessary. Stantec will prepare for and travel to two (2) advisory
meetings, at the request of the County, to provide updates at the draft report and final
report milestones. Stantec will be actively engaged with County staff during the project
duration by providing' periodic updates to discuss the analysis as the BPP update
progresses. Should additional presentations to the BCC or advisory committee be
requested by the County, Stantec can accommodate these requests in writing with the
authorization of an additional approved scope/fee.
Task 3: Sector Boundaries
Based on the results, Stantec will review the boundaries of the various Sectors (1 through 8)
within the County. The delineation of these sectors will be evaluated with respect to
dominant coastal processes, beach nourishment events, historical shoreline/volume
changes, upland development, and environmental resources. The boundaries will be left
as is for consistency purposes, unless there is a significant need to change them, such as
an overlap for beach nourishment events (i.e.the southern 2,000 ft.of Sector 4 within Sector
5).
Task 4: Sand Resources
Stantec will analyze recently available data to discuss the viability and status of the
offshore borrow areas and upland sources for future sand by-passing, beach restoration,
and dune maintenance events. Stantec will provide an update assessment of sand
locations and quantities. This will include a map of each location, distances to project
locations, estimate of the quality/quantity and a cost estimate of the sand resource. This
November 15,2018

information can be used for planning of future renourishment and maintenance events.
Information used for the task will be based solely on data collected and analyzed by others
such as the current data being collected in the southern borrow area with vibracores and
the investigation into the feasibility of upland sand sources in the area.
Task 5: Storm Vulnerability
Stantec will provide a vulnerability assessment that will include performing a storm damage
vulnerability analysis by utilizing the Storm Induced Beach Change Model (SBEACH) which
simulates changes in the beach profile that could result from coastal storms of varying
intensity in terms of storm tide levels, wave heights.wave periods, and storm duration.This
assessment will follow a similar approach, to those used in previous BPP updates.
Information required as input to run the SBEACH model includes the beach cross-section,
the median sediment grain size, and the time histories of the wave height, wave period,
and water elevation.This information will be gathered from existing data sources. No new
collection of data is proposed. If it is determined that the available data is insufficient to
develop an accurate model, then collection of additional data will be discussed with the
County.
Sea level rise will be discussed as it relates to the management strategies and how the
County can include sea level rise in their planning efforts. This discussion will be restricted
to the impacts of sea level rise on the proposed beach management strategies but will
also include a narrative on the Florida Statute requirements for local governments to
prepare comprehensive plans to include sea level rise considerations in their future
planning documents. Impacts of sea level rise to infrastructure close to the beach will not
be included.
Task 6: Storm Damage Reduction Analysis
The analysis of potential storm damages will be followed by an evaluation of the size of a
beach fill that would be required to eliminate the potential damage identified with a
particular storm return interval. SBEACH will be re-run to determine the size of a beach fill
that would be needed to eliminate that potential threat. This process will be repeated for
each storm and each reach for which potential damages are indicated.The outcome of
this analysis will be a list of beach fill dimensions needed in each reach to eliminate storm
damage threats to structures for storm return interval deemed to pose a potential threat.
It is anticipated that no more than three storm intervals will be used for this analysis.
The results of this analysis can be used to formulate a beach nourishment strategy that
would seek to equalize the magnitude of the storm damage risk for the entire County or at
least reduce the risk to an acceptable level. The determination of what constitutes an
acceptable level of risk depends on priorities established by the County.Stantec will work
with the County to identify and confirm these priorities.

Task 7: Alternatives and Resiliency Assessment
Stantec will examine alternatives to enhance existing strategies and provide
recommendations for future consideration. Stantec will review the strategies previously
implemented and evaluate the performance of shore protection projects in terms of
whether the previous projects are meeting the Program's objectives and purpose. An
important factor in this assessment is the ability of a given alternative to be resilient. With
the dynamic nature of the coastline, implementing resilient projects is key to the long-term
success of the Program. Stantec will discuss possible alternatives (if warranted) and
provide recommendations for County consideration (i.e. more/less frequent renourishment
events, strategic placement of sand, dune restoration, coastal structures, ecosystem
enhancements, etc.). Regulatory and environmental constraints associated with the
various alternatives will be considered.
• Task 8: Environmental Resources
Stantec will review and discuss the County's influence of beach restoration on
environmental resources. This will include an assessment of the sea turtle monitoring data
and nearshore hardbottom data (and other data as deemed appropriate) to evaluate
the importance of coastal restoration. This section will also present a holistic view to how
the County's environmental program is supported by the proactive beach management
program within the County. This work will rely heavily on work performed by others and
bring together previous monitoring results in a manner to determine the effect of the
Program on local wildlife.
Task 9: Management Strategy Recommendations
Various beach management strategies will be evaluated for each sector. While all sectors
will be evaluated, it is'anticipated that focus will be on Sectors 3, 5 and 7 with respect to
management strategies, based on the previous BPP updates and a review of ongoing
efforts.Stantec will develop preliminary strategies to how best to restore and maintain the
County's coastal resources targeting a 15-year horizon.This will also include an evaluation
of data collection efforts that the County maintains to assess the Program's performance
and recommendations of any proposed improvements to enhance the monitoring of the
coastline. This section will also discuss the effectiveness of the County's beaches program
over the last 20 years. A generalized strategy will be recommended for each sector.
Task 10: Forecasting BPP Costs
Stantec will work with County staff to develop a clear and concise prediction of future
costs for the next 15 years (2020 through 2035) to administer and plan for the County's
beach program. This will include a focused cost estimate for the first 5 years and a
projection for years 5 through 15. This analysis will include predicted costs for data
collection, engineering, permitting, surveying, construction, mitigation and monitoring to
November 15,2018

assist County staff with capital expenditure planning. Costs will be provided with sufficient
detail to follow how calculations were performed.
Task 11: Funding Alternatives
Stantec will assist the County in evaluating potential funding options. A discussion of
potential funding options will be included in the BPP, such as local, State and Federal
funding sources. A brief discussion of potential local funding options such as a Municipal
Services Benefit Unit (MSBU), Municipal Services Taxing Unit (MSTU}, Erosion Prevention
District (EPD), Independent or Dependent Special Taxing Districts or parking fees will be
included. A 5-year funding strategy recommendation will be included in this section.
Task 12: BPP Update Report
Stantec will prepare a report that includes results from the BPP update. A draft report will
be provided to the County for review and comment. The report will be developed to
provide a general summary that will be easy to understand and comprehend by multiple
audiences. The main body of the report will be prepared with this consideration and any
items that are more technical in nature, analyses completed, or background data will be
referenced in an appendix.
