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 Reno County, Kansas, including the Cities of Abbyville, Arlington, Buhler, Haven, Hutchinson, Langdon, Nickerson, Partridge, Plevna, Pretty Prairie, South Hutchinson, Sylvia, Turon, and Willowbrook and the unincorporated areas of Reno County (referred to collectively herein as Reno County), and 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 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 Cities of Abbeyville, Langdon, Partridge, and Plevna are non- floodprone.

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.

The Digital Flood Insurance Rate Map (DFIRM) and FIS Report for this countywide study have been produced in digital format. Flood hazard information was converted to meet the Federal Emergency Management Agency (FEMA) DFIRM database specifications and Geographic Information System (GIS) format requirements. The flood hazard information was created and is provided in a digital format so that it can be incorporated into a local GIS and be accessed more easily by the community.

1.2 Authority and Acknowledgments

The sources of authority for this Flood Insurance Study are the National Flood Insurance Act of 1968 and the Flood Disaster Protection Act of 1973.

The hydrologic and hydraulic analyses for the July 2000 study were performed by the U.S. Army Corps of Engineers (USACE), Tulsa District (the Study Contractor) for FEMA, under Inter-Agency Agreement No. EMW-83-E-1153, Project Order No. 1. This study was completed in October 1985.

The Reno County, Kansas revised county wide FIS were performed by AMEC and Earth Invironmental for the Federal Emergency Management Agency (FEMA), under Contract No. EMK-2005-CA-5010. This study was completed in October 1, 2007.

1.3 Coordination

For the July 2000 FIS, the initial Consultation Coordination Officer (CCO) meeting was held on August 11, 1982, and attended by representatives of Reno County, the Kansas State Board of Agriculture, the Study Contractor, and FEMA. On May 9, 1988, the results of this Flood Insurance Study were reviewed, and on December 6, 1989, a coordination meeting was held to further discuss community concerns about flooding along Plum Creek. This meeting was attended by representatives of the Study Contractor, FEMA, the City of Hutchinson, and Reno County.

For this countywide FIS, a CCO meeting was held on August 11, 2005. The meeting was attended by representatives of Reno County, the Kansas Department of Agriculture Division of Water Resources, FEMA, and the Cities of Nickerson, Haven, Hutchison, and Buhler.

The results of the study were reviewed at the final CCO meeting held on December 10, 2008, and attended by representatives of athe Cities of Hutchinson, Pretty Prairie, South Hutchinson, Reno County, FEMA, and the Kansas Department of Agriculture. All problems raised at that meeting have been addressed in this study.

2.0 AREA STUDIED

2.1 Scope of Study

This FIS covers the geographic area of Reno County, Kansas including the incorporated communities listed in Section 1.1.

Flooding caused by overflow of the Arkansas River, the Little Arkansas River, Little Arkansas River Tributary A, Little Arkansas River Tributary B, North Fork Ninnescah River, Plum Creek, Gar Creek, Cow Creek, Cow Creek Tributary C, Sand Creek, Salt Creek, Salt Creek Tributary A, Salt Creek Tributary B, Kisiwa Creek, Kisiwa Creek Tributary, Smoots Creek, Smoots Creek Tributary, Silver Creek Tributary, and Bull Creek were studied in detail.

Approximate analyses were used to study those areas having a low development potential or minimal flood hazards. In general, those areas previously defined using approximate methods and defined streams with one-square mile or greater contributing drainage areas were included in the approximate analysis. The scope and methods of study were proposed to, and agreed upon, by FEMA and Reno County.

2.2 Community Description

Reno County is in south-central Kansas. It is bordered by Stafford and Pratt Counties on the west, Rice and McPherson Counties on the north, Harvey and Sedgwick Counties on the east, and Kingman County on the south. Reno County is served by State Highways 61, 96, 17, and 14 and by U.S. Highway 50. The Burlington Northern railroad; the Missouri, KansasTexas Railroad; the St. Louis Southwestern Railway; the Union Pacific railroad; and the Atchison, Topeka and Santa Fe Railway pass through Reno County. The 2000 population of Reno County was reported to be

64,790 (Reference 1). The economy of Reno County is based primarily on agriculture and agriculture-related industries.

The topography of the county is characterized by flat, broad areas in tile lower river bottoms and gently rolling hills in the uplands. Soils vary from deep, nearly level, loamy soils to somewhat sandy, wind-modified soils. Most of the undeveloped land is used either for pasture or for producing grain crops. Development in the county occurs mainly in and around the City of Hutchinson.

Average monthly temperatures in the Reno County area range from 31 degrees Fahrenheit (˚F) in January to 83˚F in July. The average annual temperature is approximately 57˚F. Average annual rainfall is approximately 30 inches (Reference 2).

2.3 Principal Flood Problems

2.4 Flood Protection Measures

The Arkansas River and Cow Creek local flood protection project near Hutchinson consists of a leveed diversion canal, located about 1 mile west of the city limits and intercepting Cow Creek northwest of the city and carrying floodwaters from Cow Creek south to the Arkansas River. From there, the combined flow of the creek and the river is confined between levees on both sides of the river and carried past the city. The design flow for the Cow Creek diversion canal is 30,000 cfs, and the design flow for the Arkansas River levees is 58,500 cfs. As part of the project, over 26 miles of levees, including a ring levee in the vicinity of Island Park Subdivision, northwest of Hutchinson, were constructed (Reference 3).

Levees exist in the study area that provides the community with some degree of protection against flooding. The criteria used to evaluate protection against the 1-percent-annual-chance flood are 1) adequate design, including freeboard, 2)

structural stability, and 3) proper operation and maintenance. Levees that do not protect against the 1-percent-annual-chance flood are not considered in the hydraulic analysis of the 1-percent-annual-chance floodplain.

3.0 ENGINEERING METHODS

For the flooding sources studied in detail 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 are expected to be equaled or exceeded once on the average during any 10-, 50-, 100-, or 500-year period (recurrence interval) have been selected 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 100-year flood (1-percent chance of annual exceedence) in any 50- year period is approximately 40 percent (4 in 10), and, 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 each flooding source studied by detailed methods affecting the community.

Rainfall-runoff models were developed for all detailed studied streams (except the Arkansas River and Cow Creek) using the Hydrologic Engineering Center (HEC) HEC-1 computer program (Reference 4). Snyder’s unit hydrograph coefficients, rainfall loss rates, and routing criteria were developed as input for the HEC-1 models. The unit hydrograph coefficients were selected using the USACE mean curve that relates stream slope, length, subarea shape, percent of urbanization, and hydrograph peaking time. The mean curve was previously developed using data collected from various gaged watersheds in the Tulsa District of the USACE.

Loss rates for Salt Creek and the North Fork Ninnescah River were obtained by calibrating the HEC-1 models to match the 1-percent-annual-chance frequency discharges at the gages located on the two streams. Loss rates for the Little Arkansas River and its tributaries were obtained from the HEC-1 model developed for the local flood protection project for the City of Halstead, Kansas (Reference 5). Loss rates for Kisiwa Creek and its tributary were also taken from the report for Halstead. Loss rates for Cow Creek, Bull Creek, and the Cow Creek tributaries were obtained from the “Cow Creek, Kansas, Channel Improvement, Design Memorandum No. 1” (Reference 6). Loss rates for Silver Creek Tributary and Smoots Creek and its tributary were assumed to be the same as those for the North Fork Ninnescah River because of the proximity of those streams to the river watershed Sand Creek and Gar Creek loss rates were assumed to be the same as those for Salt Creek because of the

proximity of those streams to the Salt Creek basin, which has an area of high soil permeability along the Arkansas River noted in “Kansas Streamflow Characteristics” (Reference 7).

Flood-flow frequency data for the Arkansas River and Cow Creek were obtained from the USACE Hutchinson, Kansas, Flood Insurance Studv (Reference 8). Those discharges were based on a statistical analysis of the peak flows at the Cow Creek gage located near the City of Lyons, Kansas, and the Arkansas River gage located near Hutchinson.

Flood-flow frequency data for Salt Creek; Cow Creek Tributaries A, B, and C; Plum Creek; Little Arkansas River Tributaries A and B; Smoots Creek; Smoots Creek Tributary; Gar Creek; Silver Creek Tributary; and Sand Creek were obtained using HEC-1 computer models and discharge-frequency information developed for the Salt Creek gage at Partridge as a guide curve. Rainfall amounts and distribution patterns were derived from Technical Paper No. 40 (Reference 9).

Flood-flow frequency data for the Little Arkansas River at Buhler were developed using the discharge-frequency data developed for the local flood protection project for Halstead (Reference 5). The discharge-frequency data for the Buhler area were adjusted using the discharge-frequency data for the local flood protection study as a guide curve. Rainfall amounts and patterns were developed from Technical Paper No. 40 (Reference 9).

Flood-flow frequency data for the North Fork Ninnescah River at Arlington were obtained by plotting the discharge-frequency data developed from the HEC-1 computer model and using the discharge-frequency data for the stream gage above Cheney Reservoir as a guide curve.

Peak discharge-drainage area relationships for the 10-, 2-, 1-, and 0.2-percent chance annual floods of each flooding source studied in detail in the community are shown in Table 2, Summary of Discharges.

Discharges for Zone A studies were developed using Regression Equations contained in the USGS report of Peak Stream flows for Unregulated Rural Streams in Kansas. Drainage areas along streams were determined using a flow accumulation grid developed from the USGS 10 meter digital elevation models and corrected National Hydrologic Data (NHD) stream coverage. Flow points along stream centerlines were calculated using the regression equations in conjunction with accumulated area for every 10 percent increase in flow along a particular stream.

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 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 table 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 us the flood elevation data presented in this FIS report in conjunction with the data shown on the FIRM.

Cross sections for the backwater analysis were defined at selected intervals along the study streams to model conveyance at valley sections, and at sections just upstream and downstream of bridges and culverts to compute the backwater effects of such structures. All bridges and culverts were field surveyed to obtain accurate descriptions of their condition and hydraulic openings.

Detail-studied streams that were not re-studied as part of this map update may include a “profile base line” on the maps. This “profile base line” provides a link to the flood profiles included in the FIS report. The detail-studied stream centerline may have been digitized or redelineated as part of this revision. The “profile base lines” for these streams were based on the best available data at the time of their study and are depicted as they were on the previous FIRMs. In some cases where improved topographical data was used to redelineate floodplain boundaries, the “profile base line” may deviate significantly from the channel centerline or may be outside the SFHA.

Starting water-surface elevations were based on normal depth methods. Water-surface elevations for detailed studied streams were computed using the HEC-2 step-backwater computer program (Reference 10). Locations of selected cross sections used in the hydraulic analyses are shown on the Flood Profiles and on the Flood Insurance Rate Map.

This study was revised on July 19, 2000, to show modifications to flood hazards along the Arkansas River, from downstream of U.S. Highway 50 to just downstream of the Union Pacific Railroad, and Unnamed Tributary to Sand Creek, from just upstream of U.S. Highway 50 to just upstream of Main Street in the Cities of South Hutchinson and Hutchinson and the unincorporated areas of Reno County.

The hydrologic and hydraulic analyses for the July 19, 2000 restudy of a portion of the Arkansas River and Unnamed Tributary to Sand Creek were presented in the “Special Flood Hazard Report” for South Hutchinson, Kansas, prepared by the USACE, Tulsa District, dated March 1996 (Reference 28). Data for the cross sections for the Arkansas River backwater model are based on field surveys conducted in 1995. The study limits for the 2000 restudy on the Arkansas River extend from downstream of U.S. Highway 50 to just downstream of the Union Pacific Railroad, and for Unnamed Tributary to Sand Creek, from just upstream of U.S. Highway 50 to just upstream of Main Street in the Cities of South Hutchinson and Hutchinson and the unincorporated areas of Reno County.

Cross sections for the Unnamed Tributary to Sand Creek backwater model are based on 2-foot-contour-interval aerial photogrammetric maps dated February 1995. Unnamed Tributary to Sand Creek ponds behind the South Hutchinson Levee along the Arkansas River and the U.S. Highway 50 embankment. The USACE HEC-IFH program was used for the analysis of the 1-percent-annual-chance flood elevation of the ponded area. The starting water-surface elevation for Unnamed Tributary to Sand Creek was based on the ponded elevation. For the 10-, 2-, and 0.2-percent-annual- chance floods, the profiles were calculated starting just downstream of Scott Boulevard with the starting elevations based on the slope-area method.

Flood profiles were drawn showing the computed water-surface elevations for floods of the selected recurrence intervals. In cases where the 0.2- and 1-percent-annual- chance flood elevations are close together, due to limitations of the profile scale, only the 1-percent-annual-chance profile has been shown.

Areas of the community protected by levees are subject to potential risk due to possible failure or overtopping of the levee. These areas were delineated by applying the 1-percent-annual-chance elevation determined from the “levee in place” analysis.

The hydraulic analyses for this study were based on unobstructed flow. The flood elevations shown on the Flood Profiles are thus considered valid only if hydraulic structures remain unobstructed, operate properly, and do not fail.

Countywide hydraulic modeling for the approximate study streams was performed using HEC-RAS, version 3.1.2, from the USACE HEC. AMEC’s program, Automated Floodplain Generator (AFG) was used to assist in the development of the geometries and resulting floodplains throughout the county. AFG employs methodologies of HEC-GeoRAS, a GIS interface developed by HEC for the preparation of hydraulic models. In an GIS environment, the engineer places stream centerline and cross-section cut lines. The bank lines and flow path lines are automatically placed, buffering the stream based on user-specified spacing. The AFG then extracts the vertical elevation from the background topography and creates the input geometry file for the HecRas model. Next, cross-section locations are evaluated in reference to the floodplain boundary and are manually adjusted as necessary. The bank stations, Manning’s n values, and ineffective flow areas are prescribed in the HEC-RAS model. Subsequently, the water surface elevation is extracted from the HEC-RAS model output and a water surface Triangulated Irregular Network (TIN) is created. The floodplain boundary is delineated based on the difference between the water surface TIN and ground surface TIN.

3.3 Vertical Datum

All FIS reports and Flood Insurance Rate Maps (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 newly created or revised FIS reports and FIRMs was the National Geodetic Vertical Datum of 1929 (NGVD29). With the finalization of the North American Vertical Datum of 1988 (NAVD88), many FIS reports and FIRMs are being prepared using NAVD88 as the referenced vertical datum.

To accurately convert flood elevations for Reno County from the current NGVD29 datum to the newer NAVD88 datum, the following procedure was implemented. The vertical datum shift was calculated for each corner of the USGS 7.5-minute topographic quadrangle maps located inside or within 2.5 miles of the County boundary using the the National Geodetic Survey conversion program, VertCon 2.1. A resulting average conversion factor of 0.52 ft was applied to all components of the FIS that display flood elevations.

Flood elevations shown in this FIS report and on the FIRM are referenced to the NAVD88. These flood elevations must be compared to structure and ground elevations referenced to the same vertical datum. For information regarding

conversion between the NGVD29 and NAVD88, or to obtain current elevation, description, and/or location information for benchmarks, visit the National Geodetic Survey website at www.ngs.noaa.gov, or contact the National Geodetic Survey at the following address:

NGS Information Services NOAA, N/NGS12 National Geodetic Survey SSMC-3, #9202 1315 East-West Highway Silver Spring, Maryland 20910-3282 (301) 713-3242 (301) 713-4172 (fax)

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.

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 and Floodway Data 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 in detail, the 1- and 0.2-percent-annual-chance floodplain boundaries have been delineated using the flood elevations determined at each cross section. Between cross sections, the boundaries were interpolated using topographic maps derived from aerial photographs at scales of 1:2400 and 1:7200 with a contour interval of 2 feet (Reference 11).

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, AE, AH, and AO) 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.

For the streams studied by approximate methods, only the 1-percent- annual-chance floodplain boundary was delineated using 10-meter digital elevation models (DEMs) developed in 1999 by the U.S. Geological Survey (Reference 12).

Some areas of the community that are protected from the 1-percent- annual-chance flood by a levee have been delineated as having potential risk due to possible failure or overtopping of the levee during larger floods.

4.2 Floodways

Encroachment on floodplains, such as structures and fill, reduces the flood-carrying capacity, increases the 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 1-percent-annual-chance flood can be carried without substantial increases in flood heights. Minimum Federal standards limit such increases to 1.0 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 floodway studies.

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 and are shown in Table 3, Floodway Data. The computed floodways are shown on the FIRM. In cases where the floodway and the 1-percent-annual-chance floodplain boundaries are either close together or collinear, only the floodway boundary has been shown.

Along streams where floodways have not been computed, the community must ensure that the cumulative effect of development in the floodplain will not cause more than a 1.0-foot increase in the base flood elevations at any point within the community.

The area between the floodway and the 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 the water-surface elevation of the 1-percent-annual-chance flood by more than 1.0 foot at any point.

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 Flood Insurance Study by approximate methods. Because detailed hydraulic analyses are not performed for such areas, no base flood elevations 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 Flood Insurance Study by detailed methods. Whole-foot base flood elevations derived from the detailed hydraulic analyses are shown at selected intervals within this zone.

Zone AH

Zone AH is the flood insurance rate zone that corresponds to the areas of 1-percent-annual- chance shallow flooding (usually areas of ponding) where average depths are between 1 foot and 3 feet. Whole-foot base flood elevations derived from the detailed hydraulic analyses are shown at selected intervals within this zone.

Zone AO

Zone AO is the flood insurance rate zone chat corresponds to the areas of 1-percent-annual- chance shallow flooding (usually sheet flow on sloping terrain) where average depths are between 1 foot and 3 feet. Average whole-foot depths derived from the detailed hydraulic analyses are shown within this zone.

Zone X

Zone X is the flood insurance rate zone that corresponds to areas outside the 1-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, and areas protected from the 1-percent-annual- chance flood by levees. No base flood elevations 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 risk 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 Base Flood Elevations or average depths. Insurance agents use the 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 Reno 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 Floodway Maps (FBFMs), where applicable. Historical data relating to the maps prepared for each community are presented in Table 4, “Community Map History.”

7.0 OTHER STUDIES

The USACE prepared a report titled Cow Creek, Kansas, Channel Improvement Design Memorandum No. 1 (Reference 6). The 1-percent-annual-chance floodflow for Cow Creek at Hutchinson, as developed for that study, was 22,600 cfs and the 50-year floodflow at Hutchinson was 15,800 cfs. Those flows compare closely to the flows used for this Flood Insurance Study.

The USACE also prepared a FIS for the City of Hutchinson, Kansas (Reference 8). This FIS reflects slight modification of the Arkansas River flows to account for the additional drainage area flowing into the Arkansas River at the confluence of Cow Creek.

RENO COUNTY, KS AND INCORPORATED AREAS COMMUNITY MAP HISTORY

The FISs published for McPherson, Harvey, and Sedgwick Counties (References 13-15) and the FIRM printed for Rice County are in agreement with this study (Reference 16).

A report published for the Arkansas River and Bull Creek local flood protection project for the City of Nickerson (Reference 17) is in agreement with this study.

This FIS supersedes the previously printed Flood Hazard Boundary Maps for the Cities of Arlington, Partridge, Pretty Prairie, and South Hutchinson, and Reno County, Kansas (References 18-22); the previously published FIS for the City of Nickerson, Kansas (Reference 23); and the previously printed FIRMs for the Cities of Hutchinson and Willowbrook, Kansas (References 24 and 25).

This FIS report either supersedes or is compatible with all previous studies on streams studied in this report and should be considered authoritative for purposes of the NFIP.

8.0 LOCATION OF DATA

Information concerning the pertinent data used in the preparation of this study can be obtained by contacting Federal Insurance and Mitigation Division, FEMA Region VII, 9221 Ward Parkway, Suite 300, Kansas City, Missouri 64114-3372.

Future revisions may be made that do not result in the republishing of the FIS report. To ensure that any user is aware of all revisions, it is advisable to contact the map repository of flood hazard data located in the community.
