FLOOD INSURANCE STUDY
ALLEN COUNTY, OHIO AND INCORPORATED AREAS
1.0 INTRODUCTION
1.1 Purpose of Study
This Flood Insurance Study (FIS) revises and updates information on the existence
and severity of flood hazards in the geographic area of Allen County, including the
cities of Delphos and Lima; the villages of Beaverdam, Bluffton, Cairo, Elida, Fort
Shawnee, Harrod, Lafayette, and Spencerville; and the unincorporated areas of Allen
County (referred to collectively herein as Allen County). Note that previously printed
FIS reports in Allen County exist for the cities of Lima and Delphos; the villages of
Bluffton and Fort Shawnee; and the unincorporated areas of Allen County. Within
the geographic area of Allen County, no special flood hazard areas have been
identified for the Villages of Beaverdam, Cairo, Harrod, and Spencerville. In 2012
the residents of the Village of Fort Shawnee voted to disincorporate the Village. This
is not reflected on the FIRM panels or elsewhere in this FIS.
This FIS aids in the administration of the National Flood Insurance Act of 1968 and
the Flood Disaster Protection Act of 1973. This study has developed flood-risk data
for various areas of the community that will be used to establish actuarial flood
insurance rates and to assist the community in its efforts to promote sound floodplain
management. Minimum floodplain management requirements for participation in the
National Flood Insurance Program (NFIP) are set forth in the Code of Federal
Regulations at 44 CFR, 60.3.
Please note that the Village of Bluffton is geographically located in Allen and
Hancock Counties. Also note the City of Delphos is geographically located in Allen
and Van Wert Counties. Both communities are included in this FIS report in their
entirety.
In some States or communities, floodplain management criteria or regulations may
exist that are more restrictive or comprehensive than the minimum Federal
requirements. In such cases, the more restrictive criteria take precedence, and the
State (or other jurisdictional agency) will be able to explain them.
1.2 Authorityand Acknowledgments
Hydrologic and hydraulic analyses for entire reach or portions of Auglaize River
within Allen County Dug Run, Dug Run Tributary, Hog Creek, Little Ottawa River,
Lost Creek, Ottawa River, and Sugar Creek were performed by USGS for U.S. Army
Corps of Engineers (USACE). These studies were completed in September 2010.
2
Hydrologic and hydraulic analyses for portions of Ottawa River, Lost Creek, were
provided by Natural Resource Conservation Center - NRCS (SCS). These analyses
were based on Floodplain Management Study for Ottawa River and Tributaries
completed in December 2002 (Reference 1). The results of this work were revised by
NRCS (SCS) in July 2010.
Hydrologic and hydraulic analyses for portions of Dug Run and Pike Run were
performed by Kohli and Kaliher Inc. These reaches were studied in approximate
methods in the previous FIS for Allen County Unincorporated Areas, and were not
studied by NRCS or USGS as a part of the aforementioned efforts. These analyses
were completed in July, 2010.
Hydrologic and hydraulic analysis for the Little Riley Creek was obtained from Allen
County. The study was originally performed by Hull & Associates in 2003-2004 for a
drainage improvement project for the County. The hydraulic analysis was later
modified by Hull & Associates to incorporate the field survey data obtained from the
county. CDM Federal Programs Corporation (CDM) was involved in the review of the
modified study. The work was completed in 2010.
For the countywide FIS, new approximate hydrologic and hydraulic analyses and
redelineation of special flood hazard areas were performed by CDM, under contract
HSFE05-2005-D-0027/TO12. This work was completed in October, 2010.
The digital base mapping information was provided in digital format by Allen County,
Ohio. This information was derived from data compiled from digital orthophotography
dated 2006. These data meet or exceed National Mapping Accuracy Standards. Users
of this FIS should be aware that minor adjustments may have been made to specific
Flood Insurance Rate Map (FIRM) base map features.
The coordinate system used for the production of the FIRM is State Plane, North Ohio,
North American Datum of 1983 (NAD 83), GRS 80 spheroid. Differences in the datum
and spheroid used in the production of FIRMs for adjacent counties may result in slight
positional differences in map features at the county boundaries. These differences do
not affect the accuracyof information shown on the FIRM.

1.3 Coordination
An initial Consultation Coordination Officer (CCO) meeting is held typically with
representatives of FEMA, USGS, Ohio Department of Natural Resources (ODNR),
consultants and the community to explain the nature and purpose of a FIS and to
identify the streams to be studied by detailed methods. A final CCO meeting is held
typically with representatives of FEMA, USGS, consultants and the community to
review the results of the FIS.
The dates of the initial and final CCO meetings held for previous FIS for jurisdictions
within Allen Countyare shown in Table 1, “Initial and Final CCO Meetings”.

2.2 Community Description
Allen County encompasses approximately 410 square miles in North-Western Ohio.
It is bordered by Putnam County on the North, Van Wert County on the West,
Hancock and Hardin Counties on the East and Auglaize County on the South. Allen
County is served by Interstate 75, US Route 30, the CSX railroad, Conrail, the
Norfolk Southern Railway, and the Grand Trunk Western Railroad. The population
of Allen Countywas reported to be 112,241 in 1980, 109,755 in 1990 and 108,473 in
2000 (Reference 7).
The climate of Allen County is characterized as continental, with warm, humid
summers and cold winters. However, Lake Erie has an effect on the climate,
retarding the spring thaw and autumn freeze (Reference 4). Temperatures range from
a mean low of 17.5 degrees Fahrenheit (°F) in January to a mean high of 85.1 °F in
July. The mean annual snowfall for the area is approximately 25 inches and the mean
annual rainfall is approximately 35 inches, the majority occurring from November
through March (Reference 6).
Precipitation during the dormant season is generally caused by cyclonic storms
characterized by long duration and low intensity. During the growing season,
precipitation is in the form of frontal and isolation convection storms
(thunderstorms). Thunderstorms are characterized by relatively short duration rains
of high intensity (Reference 2).
The county is primarily rural and agriculture is an important industry; a little over
half the acreage of the county is cropland. The principal crops are corn, soybeans,
wheat, oats and hay. The County of Lima, however, is experiencing growth trends
common to larger cities. The area is largely residential in character, typical around a
suburb of a major city (Reference 5).
The relief of the county is nearly level to rolling. Allen County is in the Central
Lowlands area, which was completely covered by late Wisconsin glaciers. Glacial
drift, overlying limestone bedrock, ranges in thickness from a few feet to several
hundred feet throughout the county. Most of the county is till plain, but three end
10
moraines, (glacial deposits) lie across the county from east to west. Relief is more
pronounced and erosion is a bigger problem in the morainic areas.
Within the City of Lima, the depth of the glacial drift is quite variable; ranging from
a few feet to several hundred feet in thickness. Average depths are between 25 and
75 feet and overlie dolomite rock of the Monroe limestone formation. The City of
Lima itself lies in a “V” where two old streams (now buried) joined to form a
tributary to the old Teays River which was located in the west near Lake Saint
Mary’s (Reference 5).
All the major streams of Allen County are part of the Maumee River watershed,
except for a small section at the eastern edge of the county that is part of the Scioto
River watershed (Reference 6).
2.3 Principal Flood Problems
Floods of streams in the county are most frequent in the winter and spring, when
heavy rains fall on snow-covered or frozen ground. Occasionally, floods occur
following intense summer thunderstorms (Reference 6).
Within the Village of Bluffton, damages of agricultural land occur from flooding
along Little Riley Creek (Reference 6). USGS gaging stations are located in Findlay
(No. 04189000) and Glandorf (No. D4189500).
Within the City of Lima, major flooding along the Ottawa River has been mainly
confined to areas outside the City of Lima. Some flooding does occur, however, in
the northeast and southwest section of the city (Reference 5). The greatest flood event
on record in the City of Lima occurred in 2007 due to several rounds of heavy
rainfall. Much of the rainfall fell into the Maumee River basin causing flooding
throughout the entire county with numerous road closures and some evacuations
(Reference 8).
The Ottawa River channel is maintained through the city, but there is no established
channel maintenance program outside the corporate limits. The area of the channel
passing the stone quarry has been rerouted, and the capacity is inadequate for high
flows. A sharp turn in the channel at Schoonover Park is followed by a constricting
arch bridge under the Pennsylvania Railroad. This combination of physical
constriction often causes floodwater to back up, increasing flood heights upstream of
the park (Reference 5).
Portions of Ottawa River have well vegetated stream banks that provide a natural
corridor and important habitat in areas of decreasing habitat. Stream habitat in both
the Ottawa River and most of its tributaries has been diminished in part by channel
modification (straightening and impoundments) and excess nutrients and sediments
(Reference 1).
11
Flooding occurred through much of Ohio in March 1913, the result of one of the
most intense rainstorms ever recorded in northwestern Ohio (Reference 6).
However, on March 14, 1978 the Village of Fort Shawnee recorded a major flooding
event when 0.7 inches of rain fell on the frozen snow cover of the area (Reference 3).
More recent flooding in Fort Shawnee occurred in 2003 when 3 inches of rain fell
across the area causing water to flow up to about a foot deep in some areas
(Reference 8).
In January 1959, the Ottawa River reached flood staged in several areas within the
study limits. Most of the area between Schoonover Park and Thayer Road
experienced varying degrees of flooding. During the flood period, rain fell on snow
and frozen ground, and the water rose rapidly upstream from the stone quarry. An ice
jam occurred at the Rousch Road Bridge aggravating already dangerous conditions.
During the night, the waters spilled over the dike portion of track and filling the
sludge pit and lowland south of the railroad. It has been estimated that 3,000 to
5,000 acre-feet of water overflowed the channel at the break. The water immediately
receded around the Rousch Road area after the break. As a result, the river never
reached a very high crest below the quarry (Reference 5).
Other flood of lesser intensity occurred on the Ottawa River in April 1904, December
1916, January 1937, March 1939, May 1943, June 1957, February 1959 and April
1964. Smaller floods have occurred at more frequent intervals, with minor flooding
in lower areas occurring almost annually (Reference 5). More recent minor flooding
events have occurred in 1993, 1994, and 1995 with minor flooding and road closures
reported (Reference 8).
2.4 Flood Protection Measures
The only known flood protection measures are within the City of Lima. The existing
Ottawa River channel through the main portion of the city is deep, with relatively
steep banks, and is maintained within Lima. There is no established maintenance
program outside the corporate limits. Since levees, dams, and control works are not
economically feasible, it is important that the proper use and development of the
flood plain be guided by factual information concerning the flood history and
potential future floods. Similarly, protection against flooding is not provided along
Pike Run or Lost Creek. None of the dams along the different streams are used for
flood control (Reference 5).
3.0 ENGINEERING METHODS
For the flooding sources studied by detailed methods in the community, standard hydrologic
and hydraulic study methods were used to determine the flood-hazard data required for this
study. Flood events of a magnitude that is expected to be equaled or exceeded once on the
average during any10-, 50-, 100-, or 500-yearperiod (recurrenceinterval) have been selected
12
as having special significance for floodplain management and for flood insurance rates.
These events, commonly termed the 10-, 50-, 100-, and 500-year floods, have a 10-, 2, 1-,
and 0.2-percent chance, respectively, of being equaled or exceeded during any year.
Although the recurrence interval represents the long-term, average period between floods of a
specific magnitude, rare floods could occur at short intervals or even within the same year.
The risk of experiencing a rare flood increases when periods greater than 1 year are
considered. For example, the risk of having a flood that equals or exceeds the 1- percent-
annual-chance flood in any 50-year period is approximately 40 percent (4 in 10); for any
90-year period, the risk increases to approximately 60 percent (6 in 10). The analyses
reported herein reflect flooding potentials based on conditions existing in the community at
the time of completion of this study. Maps and flood elevations will be amended
periodically to reflect future changes.
3.1 Hydrologic Analyses
Hydrologic analyses were carried out to establish peak discharge-frequency
relationships for the flooding sources studied in detail affecting the county.
Note that previously printed FIS reports in Allen Countyexist for the City of Delphos
and Lima, Villages of Bluffton and Fort Shawnee and the unincorporated areas of
Allen County. The hydrologic analysis described in those reports have been
compiled and summarized below.
Pre-Countywide Analysis:
Hydrologic analyses were carried out to establish the peak discharge-frequency
relationships for each riverine flooding source studied in detail affecting the
community.
There were no stream gage stations for Flat Fork Creek, Jennings Creek, Lost Creek,
Dug Run or Dug Run Tributary; therefore, the peak discharges for those streams were
calculated using ODNR Bulletin No. 45 (Reference 9). Basin characteristics, such as
drainage area and channel slope, were determined using topographic maps (Reference
10). The average annual precipitation values were taken from Bulletin No. 45.
The Ottawa River gage at the City of Allentown, Ohio (No. 04187500), about six
miles downstream from the City of Lima, was the principal course of data for
defining discharge-frequency relationships for the Ottawa River, Lost Creek
Tributary, and Pike Run. The basic procedures for discharge-frequency analyses are
outlined in Bulletin No. 17 (Reference 11). A computer program was used for the
analysis and the generalized regional skew coefficient at Allentown was applied. The
coefficient was calculated using data from stations with at least 25 years of record
within a 100-mile radius of the Allentown stations.
13
For the Ottawa River at the Allentown Station, peak rates of flow for the 10-, 2-, 1-,
and 0.2-percent-annual-chance floods were determined using the above methods of
flood frequency analyses. The discharge rates were then factored using a ratio of the
drainage area to calculate the Ottawa River peak rates of flow through Lima.
Flow rates for Lost Creek Tributary and Pike Run were first developed using the
procedures specified in ODNR Bulletin No. 43 (Reference 12). Secondly, the
method outlined in the Report 76-768 was applied (Reference 13). The floods in the
Open File Report were applied with the Burgess and Niple curves for urbanization
and both methods compared favorably (Reference 9).
Flood discharges for the Freed Ditch, Unnamed Tributary to Freed Ditch, Riley
Creek, Little Ottawa Creek, and tributaries were established using the NRCS (SCS)
TR-20 (Reference 14). Soil compositions, slope, vegetation, land use, rainfall
intensity, and drainage area are input parameters to this computer program
(Reference 3).
This version of TR-20 uses modified Att-Kin procedure of stream and valley flood
routing. The TR-20 model was calibrated to match the frequency flow distributions
of the gaging stations at Findlay (No. 04189000) and at Glandorf (No. 04189500) and
of the FISs for the City of Mt. Blanchard (Reference 15) and the unincorporated areas
of Hancock County (Reference 16).
Countywide Analysis:
For the detailed analyses carried out by USGS for Auglaize River within Allen
County boundary, Dug Run, Dug Run Tributary, Hog Creek, Little Ottawa River,
Lost Creek (from confluence to approximately 2 miles upstream and between Thayer
and Cool roads), Ottawa River (upstream of Thayer Road) and Sugar Creek
(upstream of Napoleon Road), all estimates of 1-percent-annual-chance peak
discharges for all streams were initially determined using the methods described in
USGS report of Techniques for estimating Flood-Peak Discharges of Rural
Unregulated Streams in Ohio (Reference 17). Basin characteristics were determined
by 1992 National Land Cover data set (Reference 18) in conjunction with
topographic data. These discharges were calibrated based on previous analyses and
the engineering judgment.
For Auglaize River- Reach1, the regression estimates were calibrated using records
of USGS stream gage (04186500, Auglaize River near Fort Jennings) operated for a
total of 76 years (1922-1936, 1941-2001) using the techniques outlined in the
aforementioned USGS report.
For Ottawa River, the regression estimates were calibrated using records of the
USGS stream gage (04187500 on Ottawa River at Allentown operated) for a total of
14
52 years (1924-1935, 1939, 1943-1981) using the techniques outlined in the
aforementioned USGS report.
For the detailed studies carried out by NRCS for Lost Creek (between 3,000 upstream
of Bowman Road and Thayer Road), Ottawa River (from Thayer Road to Allen
County boundary with Putnam County except the areas within City of Lima), Sugar
Creek (downstream of Napoleon Road) and Pike Run (downstream of Cole Street)
discharges were determined using NRCS (SCS) Technical Release No. 20 (Reference
14). Curve numbers were developed using soils and landuse data provided by ODNR.
These discharges were checked and calibrated through the use of the USGS stream
gage at Allentown.
For the reaches on Pike Run by Kohli and Kaliher, discharges were developed using
the NRCS (SCS) Technical Release No. 20 (Reference 14).
For Little Riley Creek analyses were carried out using HEC HMS computer model.
The model used SCS curve number method to estimate the losses, Snyder’s Unit
Hydrograph method in conjunction with Muskingum Cunge routing and Exponential
Recession method for base flow were used to transform rainfall to runoff. The
precipitation values were obtained from Rainfall Frequency Atlas of the Midwast-
Bulletin71. The model was calibrated using a rainfall data from a rain gage data and
field observed stream data obtained from two stream gages strategically located in the
creek.
For the Countywide study, the discharges for the flooding sources studied by
approximate methods were determined using the regression equations available in
StreamStats for Ohio. The GIS applies StreamStats to facilitate the estimations of
streamflow statistics at ungaged streams (Reference 19). Flood-frequency estimates
determined by means of log-Pearson Type III analyses are reported along with
weighted flood frequency estimates, computed as a function of the log-Pearson Type
III estimates and the regression estimates (Reference 17). A discharge-drainage area
relationship was developed for each river to determine discharge at various locations in
the study reaches.
A summary of the drainage area-peak discharge relationships for all of the streams
studied by detailed methods is shown in Table 5, “Summary of Discharges”.

3.2 Hydraulic Analyses
Analyses of the hydraulic characteristics of flooding from the sources
studied were carried out to provide estimates of the elevations of floods of
the selected recurrence intervals. Users should be aware that flood
elevations shown on the FIRM [Flood Insurance Rate Map (FIRM)]
represent rounded whole-foot elevations and may not exactly reflect the
elevations shown on the Flood Profiles or in the Floodway Data tables in
the FIS report. Flood elevations shown on the FIRM are primarily intended
for flood insurance rating purposes. For construction and/or floodplain
management purposes, users are cautioned to use the flood elevation data
presented in this FIS in conjunction with the data shown on the FIRM.
Note that previously printed FIS reports in Allen Countyexist for the Cityof
Delphos and Lima, Villages of Bluffton and Fort Shawnee and the
unincorporated areas of Allen County. The hydraulic analysis described in
those reports have been compiled and summarized below.
Pre-Countywide
Analysis:
For the original studies, cross section data for the streams studied were
obtained by field survey, topographic maps (Reference 10), and aerial
photography and photogrammetry (Reference 20). Bridges were surveyed to
obtain elevation data and structural geometry. Cross sections between
bridges were provided by the Allen County Engineer’s Office.
For Dug Run, Dug Run Tributary, Lost Creek, Lost Creek Tributary, the
Ottawa River, and Pike Run, water-surface profiles were developed using
22
the HEC-2 step- backwater computer program (Reference 21). For Dug Run,
Dug Run Tributary, and Lost Creek, main stream computations were started
at normal depth. WSELs at the confluence of the main streams were used as
starting elevations for the tributaries. Starting WSELs for Lost Creek
Tributary, the Ottawa River, Jennings Creek and Pike Run were determined
using the slope-area method (Reference6). The startingWSEL for Flat Fork
Creek was determined by critical depth at a point approximately 2,200 feet
downstream of the study limit (Reference 4).
For the Little Ottawa River, Unnamed Tributary to Little Ottawa No. 1, 2, and 3,
Freed Ditch, and Riley Creek, WSELs were developed using the WSP-2 step-
backwater computer program (Reference 22). For the Riley Creek, WSELs of floods
of the selected recurrence intervals were computed. The model was calibrated by
adjusting the channel and floodplain roughness coefficients to match the June 1981
flood and the FISs for the unincorporated areas of Hancock County and the Village of
Ottawa (Reference 16). The WSP-2 step-backwater computer program was also used
to compute the selected recurrence intervals.
Flood profiles were drawn showing the computed WSELs for floods of the selected
recurrence intervals. For the Ottawa River, Lost Creek, Pike Run and Tributary to
Pike Run the recurrence interval was set to an accuracy of 0.5 feet for floods.
WSELs of floods of the selected recurrence intervals were computed through the use
of the USACE HEC-2 step-backwater computer program (Reference 21). All starting
WSELs for all streams were determined using slope-area computations.
Countywide Analysis:
For the detailed analyses carried out by USGS for Auglaize River within Allen
County boundary, Dug Run, Dug Run Tributary, Hog Creek, Little Ottawa River,
Lost Creek (from confluence to approximately 2 miles upstream and between Thayer
and Cool roads), Ottawa River (upstream of Thayer Road) and Sugar Creek
(upstream of Napoleon Road), cross sections were surveyed and supplemented by a
digital 1-foot contour map acquired from Allen County Engineers office (ACEO).
The 1-foot contours were however, generated from the DEM with accuracyof 2-foot
contour level.
USACE HEC-RAS v. 4.0 (Reference 23) hydraulic model, following HEC-2
conveyance computations option, was used to model flood profiles. After the initial
hydraulic models calculations were completed, warnings presented by the HEC-RAS
model were reviewed. The results were assessed for validity, accuracy, and
appropriate engineering practices. Some of the areas of concern included: critical
WSEL calculations, surcharge, WSEL differences between adjacent cross-sections,
and correct usage of ineffective flow areas. After the initial areas of concern were
addressed, the HEC-RAS models were recalculated. All remaining warnings
generated by HEC-RAS were reviewed and judged acceptable for the final models.
All hydraulic structure computations were reviewed for the appropriate modeling
23
solutions. Initial reviews focused on the type of solution computed at each structure
(energy equation based or based on pressure and/or weir-flow equations). In the cases
where road overflow occurred at a culvert, a submergence check was made. In the
cases where the hydraulic model computed weir flow at a culvert that was determined
to be submerged, the culvert was replaced with composite sections.
Initial floodway computations were based upon equal conveyance reduction. In some cases, subsequent floodway boundaries were then modified, to reduce significant variation in floodway widths or undesirable fluctuation in surcharges, using best engineering judgment to produce the final floodway for the reach.
For the detailed studies carried out by NRCS for Lost Creek (between 3,000 upstream
of Bowman Road and Thayer Road), Ottawa River (from Thayer Road to Allen
County boundary with Putnam County except the areas within City of Lima), Sugar
Creek (downstream of Napoleon Road) and Pike Run (downstream of Cole Street),
cross section data for the streams studied were obtained by field surveys conducted
by the Allen County Engineer’s office between December 1194 and April 1999. This
consisted of approximately 163 cross-sections, of which 94 were valley and channel
and 69 were road and bridge sections.
WSELs were developed through the use of USACE’s HEC-RAS v. 3.01 program
(Reference 23) and compared with profiles that were developed for historical storm
discharges and high water marks. Floodway computations were based upon equal
conveyance reduction.
For the reaches on Dug Run and Pike Run studied by Kohli and Kaliher, hydraulic
analysis for the various recurrence intervals was performed utilizing USACE’s HEC-
RAS Program v.3.1 (Reference 23). Cross-section information, were obtained from
Allen County Engineer’s office. Roughness coefficients (Manning's "n") for the
channel and the overbanks were determined by site visits and photographs.
Little Riley Creek Hydraulic analysis was performed using USACE HEC-RAS v 4.0.
The channel geometry was obtained from 30 m DEM topographic data using HEC-
GeoRAS. The topographic data was complemented by survey data of the hydraulic
structures and channels. The surveyed highwater marks were not available. However,
the model results were calibrated based on the known highwater marks collected
from the watershed residents.
For the flooding sources which are by studied approximate analyses and listed in “2.1
Scope of Study”, HEC-GeoRAS (Reference 24) was used to convert centerline and
cross section data created in ArcGIS (Reference 25) for use in HEC-RAS 4.0
(Reference 23). HEC-GeoRAS utilized a model developed from 2.5 feet resolution
National Elevation Dataset (NED) Digital Elevation Model (DEM) files to develop
the model cross sections. The same DEM was used for floodplain mapping. Road
crossing locations were selected by looking at the aerial photos and modeled as inline
structures. Normal depth was used as the downstream boundary condition for
reaches in this study. The slope was calculated using the channel invert profile
24
between the five most downstream cross sections (approximately most downstream
mile of channel).
Roughness coefficients (Manning's "n") listed below at Table 7 and contraction
and expansion loss coefficients used in the hydraulic computations were chosen
by engineering judgment and based on field observation of the streams and
floodplain areas

Locations of selected cross sections used in the hydraulic analyses are shown on the
Flood Profiles (Exhibit 1). For stream segments for which a floodway was computed
(Section 4.2), selected cross-section locations are also shown on the FIRM.
The hydraulic analyses for this study were based on unobstructed flow. The flood
elevations shown on the Flood Profiles (Exhibit 1) are thus considered valid only if
hydraulic structures remain unobstructed, operate properly, and do not fail.
3.3 Vertical Datum
All FISs and FIRMs are referenced to a specific vertical datum. The vertical datum
provides a starting point against which flood, ground, and structure elevations can be
referenced and compared. Until recently, the standard vertical datum in use for
25
newly created or revised FISs and FIRMs was the National Geodetic Vertical Datum
of 1929 (NGVD). With the completion of the North American Vertical Datum of
1988 (NAVD), many FIS reports and FIRMs are now prepared using NAVD as the
referenced vertical datum.
Flood elevations shown in this FIS report and on the FIRM are referenced to NAVD.
These flood elevations must be compared to structure and ground elevations
referenced to the same vertical datum. Some of the data used in this revision were
taken from the prior effective FIS reports and FIRMs and adjusted to NAVD. The
datum conversion factor from NGVD to NAVD in Allen Countyis -0.5 feet (NGVD
– 0.5 = NAVD).

Temporary vertical monuments are often established during the preparation of a
flood hazard analysis for the purpose of establishing local vertical control.
Although these monuments are not shown on the FIRM, they may be found in the
Technical Support Data Notebook associated with the FIS report and FIRM for
this community. Interested individuals may contact FEMA to access these data.

4.0 FLOODPLAIN MANAGEMENT APPLICATIONS
The NFIP encourages State and local governments to adopt sound floodplain management
programs. To assist in this endeavor, each FIS report provides 1-percent-annual-chance
floodplain data, which may include a combination of the following: 10-, 2-, 1-, and 0.2-
percent-annual-chance flood elevations; delineations of the 1- and 0.2-percent-annual-chance
floodplains; and a 1-percent-annual-chance floodway. This information is presented on the
FIRM and in many components of the FIS report, including Flood Profiles, Floodway Data
tables, and Summary of Stillwater Elevation tables. Users should reference the data
presented in the FIS report as well as additional information that may be available at the local
community map repository before making flood elevation and/or floodplain boundary
determinations.
4.1 Floodplain Boundaries
To provide a national standard without regional discrimination, the 1-percent-annual-
chance flood has been adopted by FEMA as the base flood for floodplain
management purposes. The 0.2-percent-annual-chance flood is employed to indicate
additional areas of flood risk in the community. For each stream studied by detailed
methods, the 1- and 0.2-percent-annual-chance floodplain boundaries have been
delineated using the flood elevations determined at each cross section.
Within Allen County, between cross sections the boundaries were interpolated using
topographic information with a contour interval of 2 feet this information was
provided by Allen County. In addition, Allen County provided contour data with 1
foot interval. This data not follow FEMA minimum requirements but was utilized as
a supplemental reference. For the areas of the City of Delphos and Village of
Bluffton of Allen County, the boundaries were interpolated using topographic
information with a contour interval of 4 feet derived from Ohio Statewide Imagery
Program (O.S.I.P) photographic data.
The 1- and 0.2-percent-annual-chance floodplain boundaries are shown on the FIRM.
On this map, the 1-percent-annual-chance floodplain boundary corresponds to the
boundary of the areas of special flood hazards (Zones A and AE), and the 0.2-
percent-annual-chance floodplain boundary corresponds to the boundary of areas of
moderate flood hazards. In cases where the 1- and 0.2-percent-annual-chance
floodplain boundaries are close together, only the 1-percent-annual-chance floodplain
boundary has been shown. Small areas within the floodplain boundaries may lie
above the flood elevations, but cannot be shown due to limitations of the map scale
and/or lack of detailed topographic data.
27
For the streams studied by approximate methods, only the 1-percent-annual-chance

4.2 Floodways
Encroachment on floodplains, such as structures and fill, reduces flood-carrying
capacity, increases flood heights and velocities, and increases flood hazards in areas
beyond the encroachment itself. One aspect of floodplain management involves
balancing the economic gain from floodplain development against the resulting
increase in flood hazard. For purposes of the NFIP, a floodway is used as a tool to
assist local communities in this aspect of floodplain management. Under this
concept, the area of the 1-percent-annual-chance floodplain is divided into a
floodway and a floodway fringe. The floodway is the channel of a stream, plus any
adjacent floodplain areas, that must be kept free of encroachment so that the base
flood can be carried without substantial increases in flood heights. Minimum Federal
standards limit such increases to 1 foot, provided that hazardous velocities are not
produced. The floodways in this study are presented to local agencies as minimum
standards that can be adopted directly or that can be used as a basis for additional
floodwaystudies.
The floodways presented in this study were computed for certain stream segments on
the basis of equal-conveyance reduction from each side of the floodplain. Floodway
widths were computed at cross sections. Between cross sections, the floodway
boundaries were interpolated. The results of the floodway computations are tabulated
for selected cross sections (see Table 9, Floodway Data). In cases where the
floodway and 1-percent-annual-chance floodplain boundaries are either close
together or collinear, only the floodway boundary is shown.
The area between the floodway and 1-percent-annual-chance floodplain boundaries is
termed the floodway fringe. The floodway fringe encompasses the portion of the
floodplain that could be completely obstructed without increasing WSELs of the base
flood more than 1 foot at any point. Typical relationships between the floodway and
the floodway fringe and their significance to floodplain development are shown in
Figure 1.

5.0 INSURANCE APPLICATION
For flood insurance rating purposes, flood insurance zone designations are assigned to a
community based on the results of the engineering analyses. These zones are as follows:
Zone A
Zone A is the flood insurance rate zone that corresponds to the 1-percent-annual-chance
floodplains that are determined in the FIS report by approximate methods. Because detailed
hydraulic analyses are not performed for such areas, no base (1-percent-annual-chance) flood
elevations (BFEs) or depths are shown within this zone.
Zone AE
Zone AE is the flood insurance rate zone that corresponds to the 1-percent-annual-chance
floodplains that are determined in the FIS report by detailed methods. Whole-foot BFEs
derived from the detailed hydraulic analyses are shown at selected intervals within this zone.
Zone X
Zone X is the flood insurance rate zone that corresponds to areas outside the 0.2-
percent-annual-chance floodplain, areas within the 0.2-percent-annual-chance floodplain,
areas of 1-percent-annual-chance flooding where average depths are less than 1 foot, areas of
1-percent-annual-chance flooding where the contributing drainage area is less than
1 square mile (sq. mi.), and areas protected from the base flood by levees. No BFEs or
depths are shown within this zone.
6.0 FLOOD INSURANCE RATE MAP
The FIRM is designed for flood insurance and floodplain management applications.
For flood insurance applications, the map designates flood insurance rate zones as described in
Section 5.0 and, in the 1-percent-annual-chance floodplains that were studied by detailed
methods, shows selected whole-foot BFEs or average depths. Insurance agents use zones and
BFEs in conjunction with information on structures and their contents to assign premium rates for
flood insurance policies.
For floodplain management applications, the map shows by tints, screens, and symbols, the 1- and
0.2-percent-annual-chance floodplains, floodways, and the locations of selected cross sections
used in the hydraulic analyses and floodway computations.
The countywide FIRM presents flooding information for the entire geographic area of Allen
County. Previously, FIRMs were prepared for each incorporated community and the
unincorporated areas of the County identified as flood-prone. This countywide FIRM also
includes flood-hazard information that was presented separately on Flood Boundary and
52
Floodway Maps (FBFMs), where applicable. Historical data relating to the maps prepared for
each community are presented in Table 10, “Community Map History.”
