CITY COUNCIL AGENDA MEMO
THRU: Don Marr, Chief of Staff
Jeremy Pate, Development Services Director
Chris Brown, City Engineer
FROM: Alan Pugh, Staff Engineer
DATE: August 5, 2015
SUBJECT: Approval for the City of Fayetteville to participate in a grant opportunity
with the Arkansas Natural Resources Commission (ANRC) by providing up
to $43,658 in matching funds to continue updating the Flood Insurance
Rate Maps (FIRMs) for the community.
RECOMMENDATION:
Approval for the City of Fayetteville to participate in a grant opportunity with the Arkansas
Natural Resources Commission (ANRC) by providing up to $43,658 in matching funds to
continue updating the Flood Insurance Rate Maps (FIRMs) for the community.
BACKGROUND:
Recently, ANRC, in partnership with the Federal Emergency Management Agency (FEMA)
initiated Phase 1 of the Risk Mapping, Assessment and Planning (Risk MAP) Program. This
phase included what is referred to as "discovery" and local counties and municipalities were
asked to participate by contributing monetarily, $5,000, and by identifying areas on the currently
effective FIRMs in need of update. Fayetteville participated in this discovery by identifying
several areas throughout the community where the maps are in need of update or are believed
not to be accurate for various reasons. ANRC partnered with a local engineering firm, FTN
Associates, to lead the effort and begin to compile the results. Out of that program, Fayetteville
was able to receive valuable feedback as well as what are referred to as First Order
Approximations (FOA) for many of the special flood hazard areas throughout town with little or
no technical information supporting the floodplain designation. As a result, the City is able to
utilize these studies to help property owners within these areas more accurately identify the
extent of potential flooding. However, the FOA are only a slight step forward. The next step in
the process is to begin to analyze or reanalyze the areas that were identified which leads into
the Phase 2 portion of the project.
DISCUSSION:
The proposed grant opportunity (Phase 2) includes an update to the existing flood insurance
study (FIS. In general this project will include updating approximately 29.3 miles of Zone A
streams, converting approximately 5.2 miles of Zone A Streams to Zone AE and re -delineating
approximately 47.3 miles of current Zone AE streams. The benefits to the City and property

Fayetteville, AR 72701
owners would include more accurate flood data, better customer service by staff for residents in
that more detailed information for the flood designation can be provided, potential reduction in
flood insurance rates for property owners in some cases and a potential for reduction in future
flood damage claims. Additional information regarding the project and benefits can be found
below and within the attached information.
During Phase I, Discovery Phase, Washington County, including all incorporated and
unincorporated areas, was identified as a strong candidate for a Risk Map Phase 2 project. The
Phase 2 portion of the project includes engineering and mapping to update the currently
effective Washington County, AR Flood Insurance Study (FIS) and FIRMs referred to
collectively as an FIS update.
The updated engineering and mapping developed in the proposed Phase 2 Risk MAP project
would be based on the newer aerial topographic data recently acquired by FEMA, updated
hydrology and hydraulics for the streams currently mapped as approximate, the addition of
published Base Flood Elevations (BFEs) added to the FIRMs for some select streams, that are
currently mapped as approximate, and updated or new detailed hydrologic and hydraulic
analysis for select streams in the Cities of Fayetteville and Springdale.
It should be noted that the referenced updated topographic data is being provided by
FEMA/ANRC at no cost to the county or incorporated communities. That portion of the project
was initiated in late 2014 in anticipation of the Phase 2 portion of the process and should be
complete in the fall of 2015.
This project could benefit the residents of Fayetteville in several ways.
• Current residents who own properties located within Zone A, Base Flood Elevations Not
Determined, would have more accurate information supporting the extent of the Special
Flood Hazard Area (SFHA) and more accurate information regarding the approximate
flood elevations.
• Some of the Zone A Special Flood Hazard Areas would be further analyzed in order to
convert them to Zone AE, Base Flood Elevations Determined. This proposal includes
approximately 5.2 miles of stream with the City of Fayetteville which covers many of the
tributaries to Town Branch. A list of the tributaries is included with the supporting
information attached to this memorandum. This will help the city further understand the
extent of possible flooding as well as give residents in these areas more accurate
information regarding the base flood elevation and what could be done to reduce their
risk of flooding. It also aides the resident when attempting to sell or improve their
property by being able to use previously determined based flood elevations rather than
going through the time and expense of having an engineer develop a base flood
elevation for their property.
• Some Zone AE areas will be re -delineated utilizing more recent topographic information.
This will in turn likely remove some properties from the floodplain as well as potentially
include properties that are not currently located within the floodplain. While the
properties brought into the floodplain may be subject to additional regulation, it is
important for the owners of those properties and potential developers to understand the
risk of flooding and plan accordingly. This can drastically reduce flood claims and
property loss in the future.
• Phase 2 will also include new products intended to assist communities in the
communication of risk to individual homeowners, local businesses, and emergency
managers. These products will include depth and velocity grids which can be used to
2
identify the depth of water, or the speed of the water, at a given point, such as a flooding
roadway. Probability grids can be used to demonstrate what the chance of flooding is for
a location over a 30 -year period, which is consistent with the period of a typical home
mortgage.
The proposed Phase 2 Risk MAP project is proposed to be funded using a grant from FEMA to
ANRC that will require local cost share. The total project costs for the 2015 LIDAR acquisition
and FIS update are $250,000 and $475,209 respectively, or $725,209 for the total project.
FEMA's contribution to the total project will be $612,657 and the community cost share needed
is $112,552. ANRC is requesting the City of Fayetteville contribute $43,658, which is 6% of the
total project cost, to help us meet the cost share requirements.
BUDGET/STAFF IMPACT:
Staff proposes that the funding for the project be allocated out of the Sales Tax Capital
Improvements Project 02108 — Other Drainage Improvements in an amount up to $43,658.

Re: Washington County, AR Flood Insurance Study Update
ANRC / FEMA Grant — Risk MAP Phase 2 Mapping Activity Statement 13
Dear Mr. Brown:
Recently, Arkansas Natural Resources Commission (ANRC), in partnership with the Federal Emergency
Management Agency (FEMA), initiated Phase 1 of the Risk Mapping, Assessment, and Planning (Risk
MAP) Program, which is the Discovery Phase. In preparation for and during the Discovery Phase,
Washington County, including all incorporated and unincorporated areas, was identified as a strong
candidate for a Risk MAP Phase 2 project, which includes engineering and mapping to update the current
effective Washington County, AR Flood Insurance Study (FIS) and Flood Insurance Rate Maps (FIRMs),
referred to collectively as an FIS update. In preparation for a Phase 2 Risk MAP project in late 2014,
FEMA, in conjunction with the US Geological Survey (USGS), funded aerial LIDAR acquisition and
processing for Washington County. LIDAR is a remote sensing technology used to collect data to prepare
a map or model of the ground surface. This model of the ground surface is often referred to as topography
and will provide the quality base for the updated engineering and mapping proposed for the Phase 2 Risk
MAP project. The LIDAR project was initiated in late 2014 and will be completed in the fall of 2015.
The 2015 LIDAR data will be available from FEMA without restriction.
The updated engineering and mapping developed in the proposed Phase 2 Risk MAP project would be
based on the newer aerial topographic data recently acquired by FEMA, updated hydrology and
hydraulics for the streams currently mapped as approximate, the addition of published Base Flood
Elevations (BFEs) added to the FIRMs for some select streams, that are currently mapped as approximate,
and updated or new detailed hydrologic and hydraulic analysis for select streams in the Cities of
Fayetteville and Springdale.
The proposed Phase 2 Risk MAP project would be funded using a grant from FEMA to ANRC that will
require local cost share. The total project costs for the 2015 LIDAR acquisition and FIS update are
$250,000 and $475,209 respectively, or $725,209 for the total project. FEMA's contribution to the total
project will be $612,657 and the community cost share needed is $112,552. We are requesting the City of
Fayetteville contribute $43,658, which is 6% of the total project cost, to help us meet the cost share
requirements.
Washington County, AR Flood Insurance Study Update
July 28, 2015
Page 2
The proposed Phase 2 Risk MAP tasks of a countywide FIS update project will involve several different
types of stream analyses and resulting mapping. The following summarizes the types of analyses and
stream mileages within your community that are identified to receive new floodplain mapping as part of
the proposed FIS update.
The proposed FIS update will include performing updated approximate hydrologic and hydraulic
analyses and updated floodplain mapping of over 436 miles of streams using the 2015 collected
LIDAR (topography) throughout the incorporated and unincorporated areas of Washington
County. The resulting special flood hazard area (SFHA) mapping will be supported by GIS and
engineering data that will be provided to the communities for use in assisting residents/property
owners in defining the BFE for their property. In the City of Fayetteville 29.3 miles will be
updated with a new approximate analysis.
The FIS update will include updating the SFHA designation from Zone A to Zone AE on
approximately 38 miles of streams within the incorporated and unincorporated areas of
Washington County. Floodplain mapping that is designated as Zone AE will have BFEs
published on the FIRMs. These specific stream miles were studied previously using a
methodology referred to as Limited Detail Study (LDS) as part of the Washington County FIS
completed in 2008. These models will also be updated with the 2015 LIDAR data that will allow
for recent man-made changes in and around the LDS streams to be accounted for in the model
without requiring the filing of individual Letters of Map Change. In the City of Fayetteville
5.2 miles of LDS streams will be updated.
The FIS update will include what is referred to as redelineation for over 100 stream miles of
current effective Zone AE floodplain mapping on the FIRMs. Redelineation retains the results of
the previously studied current effective stream model, meaning the established BFEs and
floodway remain unchanged with respect to elevation; however the SFHA boundaries will be
adjusted to be consistent with the 2015 LIDAR. For example, if the BFE on Big Creek is 1,110
ft, the elevation will remain 1,110 ft; however the boundary of the SFHA will be reviewed and
revised against the new LIDAR data to match the ground elevation of 1,110 ft using the new
LIDAR. In the City of Fayetteville 47.3 miles of existing detailed streams will be redelineated
using the new topography.
The FIS Update will include new detailed studies of several streams within the Cities of
Fayetteville and Springdale where significant changes in the drainage basin and/or the stream
channel warrant a revised analysis, or where Zone A areas are present and development pressures
exist and a detailed Zone AE SFHA with a designated floodway is warranted. Approximately 13
miles of detailed study will be performed overall which includes 7.8 miles within the City of
Fayetteville.
The stream names and associated mileage for the LDS and detailed study are provided as an attachment in
addition to a figure providing an overview of the streams to be included in the proposed Phase 2 Risk
MAP FIS Update in Washington County and the subsequent level of analysis that will be applied.
The proposed FIS update will provide many benefits to the communities in Washington County. The
LIDAR collected during the winter months of 2014-2015 provides an improved level of vertical accuracy,
supporting elevations to within +'/2 ft, as compared to the topographic base data on the current FIRMs of
+2 1/2 ft. This improved accuracy will enhance the quality of the SFHA mapping and will help reduce the
risk for those property owners who wish to develop safely and soundly in areas in/near SFHAs. A better -
defined risk area will aid property owners in making sound judgments on development opportunities,
rather than having to invest hundreds of dollars in trying to define the risk themselves. Additional
benefits will be realized with the distribution of the GIS and engineering data that will be made available
to the communities. This engineering support data will provide established base hydraulic condition for
Washington County, AR Flood Insurance Study Update
July 28, 2015
Page 3
many of the streams in the county, allowing communities and/or property owners to evaluate engineering
options such as new hydraulic structures (bridges or culverts) less expensively.
In addition to the updated FIRMs and FIS Report, new products intended to assist communities in the
communication of risk to individual homeowners, local businesses, and emergency managers are part of
the Risk MAP project. These products will include depth and velocity grids which can be used to identify
the depth of water, or the speed of the water, at a given point, such as a flooding roadway. Probability
grids can be used to demonstrate what the chance of flooding is for a location over a 30 -year period,
which is consistent with the period of a typical home mortgage. These new products and related GIS and
engineering data also allow communities to customize their own products, such as utilizing new aerial
photography, topography, parcel data, 911 data, and building footprints to assist in protecting people and
their property and establishing a sound floodplain management program.
Once FEMA confirms the proposed Phase 2 Risk MAP project cost -share requirements have been
satisfied, the Washington County FIS Update is expected to begin October 1, 2015 and culminate
December 31, 2016 with the delivery of draft FIRMs for community review.
During the community review of the draft FIRMs, ANRC and FEMA will work with the communities to
confirm their agreement to proceed to Risk MAP Phase 3, which involves converting the draft FIRMs to
formal preliminary FIRMs for publication and public review, and the subsequent regulatory processes
required for FIRM adoption. Risk MAP Phase 3 is funded entirely by FEMA. This process generally
takes approximately 1 year and will be initiated once the communities, ANRC, and FEMA agree to move
forward.
The community participation and commitment to Risk MAP is extremely important, especially during the
critical FIS Update engineering and mapping production phase. By collaborating on the engineering and
mapping phase, FEMA, ANRC, and our community partners have the opportunity to develop a
relationship whereby we all can take ownership of the FIS update process and participate in the
development and delivery of quality final products.
We need to complete our grant application, which includes documentation confirming that we have
secured our cost -share commitments, by August 21, 2015. Therefore, we respectfully request your
confirmation of your level of participation on/before August 20, 2015.
Sincerely,
J1t7

CITY COUNCIL AGENDA MEMO
DATE: April 17, 2017
SUBJECT: Approval of additional services in the amount of $9,750 to address public
concerns regarding updated draft Flood Insurance Rate Map (FIRM)
produced during the Risk Map Phase 2 project.
RECOMMENDATION:
Staff recommends approval of additional services in the amount of $9,750 to address public
concerns regarding updated draft Flood Insurance Rate Map (FIRM) produced during the Risk
Map Phase 2 project.
BACKGROUND:
On September 1, 2015, the City Council authorized the City's participation in a project referred
to as the Phase 2 Risk MAP program in cooperation with the Federal Emergency Management
Agency (FEMA) and the Arkansas Natural Resources Commission. The purpose of the project
was to take advantage of available grant funding to update the Washington County Flood
Insurance Study (FIS) and Flood Insurance Rate Maps (FIRM) in order to more accurately
define the risks associated with a flooding event. This project is now nearing completion and
preliminary maps have been provided to the City for review.
DISCUSSION:
As a part of the review process, the City was concerned that several areas were being
substantially modified and requested that the residents have an opportunity to review and
comment prior to the information being submitted to FEMA for consideration. Although this
meeting was not originally within the scope of work for the contractor working for ANRC, they
agreed to participate. During the meeting, several items of concern were noted by the public
that staff feels are in need of additional investigation prior to a submittal to FEMA.
The additional investigation includes studying in more detail portions of Skillern Tributary,
Missouri Creek, Spout Springs Branch, Scull Creek, Middle Fork of Hamestring and Sublet
Creek and is defined further within the attached letter. These areas could potentially include
structures/property within the revised floodplain in error. In order to verify the accuracy of the
maps, additional study would be required. It should be noted that none of these areas received,
or will receive, a complete detailed analysis. Rather, they were portions of re -delineated FIRMs
or limited detailed study areas included in the Phase 2 project. The process by which the maps

RE: Revised Proposal for Mapping Review and Revisions resulting from Risk MAP Open House
Washington County, AR Phase 2 Flood Risk Project
Washington County, Arkansas
FTN No. P04370-1579-001 _
Dear Mayor Jordan:
FTN Associates, Ltd. (FTN) appreciates the opportunity to submit the following revised proposal to
provide floodplain consulting services related to the ongoing Washington County, AR Phase 2 Flood
Risk Project located in Washington County, Arkansas (the Project).
Our Basic Services will generally consist of reviewing 8 areas that were determined to require
additional review beyond the original Washington County, AR Phase 2 Flood Risk Project, all as set
forth in the Scope of Work shown below and subject to the Standard Terms and Conditions
(Exhibit A), which is attached to this letter. We will also furnish such Additional Services as you
may request.
Our Basic Services for the Project will generally consist of the following tasks:
1) Data Review
a) Perform a review of the following updated hydraulic models and resultant floodplain
• mapping based on comments and/or information provided at, or subsequent to, the Open
House meetings:
• Skillern Tributary in the area of Crossover Mini Storage (application of flows and terrain
data);
• Missouri Creek adjacent to Stanton Road (application of flows); and
• Spout Springs Creek near the 7th street crossing (additional structure).
b) Perform a detailed review of the following redelineation mapping based on comments and/or
information provided at the Open House meetings:

are updated determines the relative accuracy. With this proposed additional service, the
identified areas would be studied in more detail than is required by FEMA for their designation,
however, may not be a complete detailed study in all cases. In either case, it is recommended
that this occur prior to the submittal of the draft maps to FEMA as it may be more
difficult/cumbersome later in the process to have the maps revised.

CITY COUNCIL AGENDA MEMO
THRU: Don Marr, Chief of Staff
Jeremy Pate, Development Services Director
Chris Brown, City Engineer
FROM: Alan Pugh, Staff Engineer
DATE: August 5, 2015
SUBJECT: Approval for the City of Fayetteville to participate in a grant opportunity
with the Arkansas Natural Resources Commission (ANRC) by providing up
to $43,658 in matching funds to continue updating the Flood Insurance
Rate Maps (FIRMs) for the community.
RECOMMENDATION:
Approval for the City of Fayetteville to participate in a grant opportunity with the Arkansas
Natural Resources Commission (ANRC) by providing up to $43,658 in matching funds to
continue updating the Flood Insurance Rate Maps (FIRMs) for the community.
BACKGROUND:
Recently, ANRC, in partnership with the Federal Emergency Management Agency (FEMA)
initiated Phase 1 of the Risk Mapping, Assessment and Planning (Risk MAP) Program. This
phase included what is referred to as "discovery" and local counties and municipalities were
asked to participate by contributing monetarily, $5,000, and by identifying areas on the currently
effective FIRMs in need of update. Fayetteville participated in this discovery by identifying
several areas throughout the community where the maps are in need of update or are believed
not ₹o be accurate for various reasons. ANRC partnered with a local engineering firm, FTN
Associates, to lead the effort and begin to compile the results. Out of that program, Fayetteville
was able to receive valuable feedback as well as what are referred to as First Order
Approximations (FOA) for many of the special flood hazard areas throughout town with little or
no technical information supporting the floodplain designation. As a result, the City is able to
utilize these studies to help property owners within these areas more accurately identify the
extent of potential flooding. However, the FOA are only a slight step forward. The next step in
the -process is to begin to analyze or reanalyze the areas that were identified which leads into
the Phase 2 portion of the project.
DISCUSSION:
The proposed grant opportunity (Phase 2) includes an update to the existing flood insurance
study (FIS. In general this project will include updating approximately 29.3 miles of Zone A
streams, converting approximately 5.2 miles of Zone A Streams to Zone AE and re -delineating
approximately 47.3 miles of current Zone AE streams. The benefits to the City and property

owners would include more accurate flood data, better customer service by staff for residents in
that more detailed information for the flood designation can be provided, potential reduction in
flood insurance rates for property owners in some cases and a potential for reduction in future
flood damage claims. Additional information regarding the project and benefits can be found
below and within the attached information.
During Phase I, Discovery Phase, Washington County, including all incorporated and
unincorporated areas, was identified as a strong candidate for a Risk Map Phase 2 project. The
Phase 2 portion of the project' includes engineering and mapping to update the currently
effective Washington County, AR Flood Insurance Study (FIS) and FIRMs referred to
collectively as an FIS update.
The updated engineering and mapping developed in the proposed Phase 2 Risk MAP project
would be based on the newer aerial topographic data recently acquired by FEMA, updated
hydrology and hydraulics for the streams currently mapped as approximate, the addition of
published Base Flood Elevations (BFEs) added to the FIRMs for some select streams, that are
currently mapped as approximate, and updated or new detailed hydrologic and hydraulic
analysis for select streams in the Cities of Fayetteville and Springdale.
It should be noted that the referenced updated topographic data is being, provided by
FEMA/ANRC at no cost to the county or incorporated communities. That portion of the project
was initiated in late 2014 in anticipation of the Phase 2 portion of the process and should be
complete in the fall of 2015.
This project could benefit the residents of Fayetteville in several ways.
• Current residents who own properties located within Zone A, Base Flood Elevations Not
Determined, would have more accurate information supporting the extent of the Special
Flood Hazard Area (SFHA) and more accurate information regarding the approximate
flood elevations.
• Some of the Zone A Special Flood Hazard Areas would be further analyzed in order to
convert them to Zone AE, Base Flood Elevations Determined. This proposal includes
approximately 5.2 miles of stream with the City of Fayetteville which covers many of the
tributaries to Town Branch. A list of the tributaries is included with the supporting
information attached to this memorandum. This will help the city further understand the
extent of possible flooding as well as give residents in these areas more accurate
information regarding the base flood elevation and what could be done to reduce their
risk of flooding. It also aides the resident when attempting to sell or improve their
property by being able to use previously determined based flood elevations rather than
going through the time and expense of having an engineer develop a base flood
elevation for their property.
• Some. Zone AE areas will be re -delineated utilizing more recent topographic information.
This will in turn likely remove some properties from the floodplain as well as potentially
include properties that , are not currently located within the floodplain. While the
properties brought into the floodplain may be subject to additional regulation, it is
important for the owners of those properties and potential developers to understand the
risk of flooding and plan accordingly. This can drastically reduce flood claims and
property loss in the future.
• Phase 2 will also include new products intended to assist communities in the
communication of risk to individual homeowners, local businesses, and emergency
managers. These products will include depth and velocity grids which can be used to
identify the depth of water, or the speed of the water, at a given point, such as a flooding
roadway. Probability grids can be used to demonstrate what the chance of flooding is for
a location over a 30 -year period, which is consistent with the period of a typical home
mortgage.
The proposed Phase 2 Risk MAP project is proposed to be funded using a grant from FEMA to
ANRC that will require local cost share. The total project costs for the 2015 LIDAR acquisition
and FIS update are $250,000 and $475,209 respectively, or $725,209 for the total project.
FEMA's contribution to the total project will be $612,657 and the community cost share needed
is $112,552. ANRC is requesting the City of Fayetteville contribute $43,658, which is 6% of the
total project cost, to help us meet the cost share requirements.
BUDGET/STAFF IMPACT:
Staff proposes that the funding for the project be allocated out of the Sales Tax Capital
Improvements Project 02108 — Other Drainage Improvements in an amount up to $43,658.

Re: Washington County, AR Flood Insurance Study Update
ANRC / FEMA Grant — Risk MAP Phase 2 Mapping Activity Statement 13
Dear Mr. Brown:
Recently, Arkansas Natural Resources Commission (ANRC), in partnership with the Federal Emergency
Management Agency (FEMA), initiated Phase 1 of the Risk Mapping, Assessment, and Planning (Risk
MAP) Program, which is the Discovery Phase. In preparation for and during the Discovery Phase,
Washington County, including all incorporated and unincorporated areas, was identified as a strong
candidate for a Risk MAP Phase 2 project; which includes engineering and mapping to update the current
effective Washington County, AR Flood Insurance Study (FIS) and Flood Insurance Rate Maps (FIRMs),
referred to collectively as an FIS update. In preparation for a Phase 2 Risk MAP project in late 2014,
FEMA, in conjunction with the US Geological Survey (USGS), funded aerial LIDAR acquisition and
processing for Washington County. LIDAR is a remote sensing technology used to collect data to prepare
a map or model of the ground surface. This model of the ground surface is often referred to as topography
and will provide the quality base for the updated engineering and mapping proposed for the Phase 2 Risk
MAP project. The LIDAR project was initiated in late 2014 and will be completed in the fall of 2015.
The 2015 LIDAR data will be available from FEMA without restriction.
The updated engineering and mapping developed in the proposed Phase 2 Risk MAP project would be
based on the newer aerial topographic data recently acquired by FEMA, updated hydrology and
hydraulics for the streams currently mapped as approximate, the addition of published Base Flood
Elevations (BFEs) added to the FIRMs for some select streams, that are currently mapped as approximate,
and updated or new detailed hydrologic and hydraulic analysis for select streams in the Cities of
Fayetteville and Springdale.
The proposed Phase 2 Risk MAP project would be funded using a grant from FEMA to ANRC that will
require local cost share. The total project costs for the 2015 LIDAR acquisition and FIS update are
$250,000 and $475,209 respectively, or $725,209 for the total project. FEMA's contribution to the total
project will be $612,657 and the community cost share needed is $112,552. We are requesting the City of
Fayetteville contribute $43,658, which is 6% of the total project cost, to help us meet the cost share
requirements.
Washington County, AR Flood Insurance Study Update
July 28, 2015
Page 2
The proposed Phase 2 Risk MAP tasks of a countywide FIS update project will involve several different
types of stream analyses and resulting mapping. The following summarizes the types of analyses and
stream mileages within your community that are identified to receive new floodplain mapping as part of
the proposed FIS update.
The proposed FIS update will include performing updated approximate hydrologic and hydraulic
analyses and updated floodplain mapping of over 436 miles of streams using the 2015 collected
LIDAR (topography) throughout the incorporated and unincorporated areas of Washington
County. The resulting special flood hazard area (SFHA) mapping will be supported by GIS and
engineering data that will be provided to the communities for use in assisting residents/property
owners in defining the BFE for their property. In the City of Fayetteville 29.3 miles will be
updated with a new approximate analysis.
The FIS update will include updating the SFHA designation from Zone A to Zone AE on
approximately 38 miles of streams within the incorporated and unincorporated areas of
Washington County. Floodplain mapping that is designated as Zone AE will have BFEs
published on the FIRMs. These specific stream miles were studied previously using a
methodology referred to as Limited Detail Study (LDS) as part of the Washington County FIS
completed in 2008. These models will also be updated with the 2015 LIDAR data that will allow
for recent man-made changes in and around the LDS streams to be accounted for in the model
without requiring the filing of individual Letters of Map Change. In the City of Fayetteville
5.2 miles of LDS streams will be updated.
The FIS update will include what is referred to as redelineation for over 100 stream miles of
current effective Zone AE floodplain mapping on the FIRMs. Redelineation retains the results of
the previously studied current effective stream model, meaning the established BFEs and
floodway remain unchanged with respect to elevation; however the SFHA boundaries will be
adjusted to be consistent with the 2015 LIDAR. For example, if the BFE on Big Creek is 1,110
ft, the elevation will remain 1,110 ft; however the boundary of the SFHA will be reviewed and
revised against the new LIDAR data to match the ground elevation of 1, ,llo 0 ft using the new
LIDAR. In the City of Fayetteville 47.3 miles of existing detailed streams will be redelineated
using the new topography.
The FIS Update will include new detailed studies of several streams within the Cities of
Fayetteville and Springdale where significant changes in the drainage basin and/or the stream
channel warrant a revised analysis, or where Zone A areas are present and development pressures
exist and a detailed Zone AE SFHA with a designated floodway is warranted. Approximately 13
miles of detailed study will be performed overall which includes 7.8 miles within the City of
Fayetteville.
The stream names and associated mileage for the LDS and detailed study are provided as an attachment in
addition to a figure providing an overview of the streams to be included in the proposed Phase 2 Risk
MAP FIS Update in Washington County and the subsequent level of analysis that will be applied.
The proposed FIS update will provide many benefits to the communities in Washington County. The
LIDAR collected during the winter months of 2014-2015 provides an improved level of vertical accuracy,
supporting elevations to within +'/2 ft, as compared to the topographic base data on the current FIRMs of
+2 '/2 ft. This improved accuracy will enhance the quality of the SFHA mapping and will help reduce the
risk for those property owners who wish to develop safely and soundly in areas in/near SFHAs. A better -
defined risk area will aid property owners in making sound judgments on development opportunities,
rather than having to invest hundreds of dollars in trying to define the risk themselves. Additional
benefits will be realized with the distribution of the GIS and engineering data that will be made available
to the communities. This engineering support data will provide established base hydraulic condition for
Washington County, AR Flood Insurance Study Update
July 28, 2015
Page 3
many of the streams in the county, allowing communities and/or property owners to evaluate engineering
options such as new hydraulic structures (bridges or culverts) less expensively.
In addition to the updated FIRMs and FIS Report, new products intended to assist communities in the
communication of risk to individual homeowners, local businesses, and emergency managers are part of
the Risk MAP project. These products will include depth and velocity grids which can be used to identify
the depth of water, or the speed of the water, at a given point, such as a flooding roadway. Probability
grids can be used to demonstrate what the chance of flooding is for a location over a 30 -year period,
which is consistent with the period of a typical home mortgage. These new products and related GIS and
engineering data also allow communities to customize their own products, such as utilizing new aerial
photography, topography, parcel data, 911 data, and building footprints to assist in protecting people and
their property and establishing a sound floodplain management program.
Once FEMA confirms the proposed Phase 2 Risk MAP project cost -share requirements have been
satisfied, the Washington County FIS Update is expected to begin October 1, 2015 and culminate
December 31, 2016 with the delivery of draft FIRMs for community review.
During the community review of the draft FIRMs, ANRC and FEMA will work with the communities to
confirm their agreement to proceed to Risk MAP Phase 3, which involves converting the draft FIRMs to
formal preliminary FIRMS for publication and public review, and the subsequent regulatory processes
required for FIRM adoption. Risk MAP Phase 3 is funded entirely by FEMA. This process generally
takes approximately I year and will be initiated once the communities, ANRC, and FEMA agree to move
forward.
The community participation and commitment to Risk MAP is extremely important, especially during the
critical FIS Update engineering and mapping production phase. By collaborating.on the engineering and
mapping phase, FEMA, ANRC, and our community partners have the opportunity to develop a
relationship whereby . we all can take ownership of the FIS update process and participate in the
development and delivery of quality final products.
We need to complete our grant application, which includes documentation confirming that we have
secured our cost -share commitments, by August 21, 2015. Therefore, we respectfully request your
confirmation of your level of participation on/before August 20, 2015.
Sincerely,
