The City of Prairie Grove is non-flood-prone. This Flood Insurance Study 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. This information will also be used by Washington County to update existing floodplain regulations as part of the Regular Phase of the National Flood Insurance Program (NFIP), and by local and regional planners to further promote sound land use and floodplain development. 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 . 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 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 . This study was prepared to include incorporated communities within Washington County in a countywide Flood Insurance Study. Information on the authority and acknowledgements for each of the previously printed Flood Insurance Studies and Flood Y Insurance Rate Maps for communities with the county, compiled from their effective Flood Insurance Study reports, is shown below.

This work was completed in September 1988. Also in this countywide study, updated hydraulic analyses for Tributaries 1 and 5 , within the City of Springdale, were prepared by the USACE, Little Rock District, under agreement with FEMA. This work was completed in March 1988. An updated hydraulic analysis for Mud Creek, within the City of Fayetteville, was prepared by Crafton, Tull and Associates, Inc. This work was completed in October 1988. A restudy that involved a revised hydraulic analysis for Brush Creek Tributary, within the City of Springdale, was prepared by the USACE, Little Rock District in June 1985 , and has been incorporated into this revised study. Hydrologic and hydraulic analyses for Main Ditch, in the Town of Tontitown, were prepared by the USACE, Little Rock District, and were submitted to FEMA in February 1990. 1 .3 Coordination The dates of the initial and final Consultation Coordination Officer's (CCO) meetings held ` for Washington County and the incorporated communities within its boundaries are shown in the following tabulation. Community Name Initial CCO Date Final CCO Date City of Fayetteville December 18, 1975 April 25 , 1979 City of Johnson July 28, 1978 July 18, 1979 City of Springdale June 1977 July 24, 1980 City of West Fork June 1977 May 28, 1979 Unincorporated Areas April 9, 1986 August 29, 1990 2 The initial CCO meetings were held with representatives from FEMA, the communities , and the study contractors to explain the nature and purpose of Flood Insurance Studies, and to identify the streams to be studied by detailed methods. The final CCO meetings were held with representatives from FEMA, the communities, and the study contractors to review the results of the studies . The final CCO meeting for the unincorporated areas of Washington County also served as the final CCO meeting for this countywide study and was open to representatives from all communities within the county that were included in this countywide study. • The preparation of this countywide Flood Insurance Study was coordinated with Washington County, the Arkansas Highway and Transportation Department, the Soil Conservation Service (SCS), and the U. S. Geological Survey (USGS). v 2.0 AREA STUDIED 2. 1 Scope of Study This Flood Insurance Study covers the geographic areas of the Washington County, Arkansas. The area of study is shown on the Vicinity Map (Figure 1). Table 1 , "Scope of Study, " lists the limits of study for the flooding sources studied by detailed methods. In this countywide study, Tributary 1 was restudied from a point approximately 80 feet downstream of the Burlington Northern Railroad bridge to a point approximately 0.96 mile upstream of Old Missouri Road; Tributary 5 was restudied from its confluence with Tributary 4 to a point approximately 0.59 mile upstream. This countywide study incorporates the effects of alignment and channelization projects carried out on Tributaries 1 and 5. This countywide study also incorporates the determinations made in a Letter of Map Revision, issued by FEMA, that redelineated the 100-year floodplain boundaries for Mud Creek on the basis of updated topographic information. As part of an updated hydraulic analysis of the stream referred to as Brush Creek in the previously printed Flood Insurance Study for the City of Springdale, the name of the stream was changed to Brush Creek Tributary; this countywide study includes analyses of flood hazards along another stream now referred to as Brush Creek. In this study, detailed hydrologic and hydraulic analyses were added for Main Ditch, in the Town of Tontitown. Changes in the corporate limits for the City of Fayetteville, the City of Springdale, and the City of West Fork have also been included in this countywide study . The areas studied by detailed methods were selected with priority given to all known flood hazard areas and areas of projected development and proposed construction. The following flooding sources were studied by approximate methods : Ballard Creek, Banan Fork, Beatty Branch, Beaver Lake, Blackburn Creek, Blair Creek, Budd Kidd Creek, Bush Creek, Bushy Creek, East Fork Cato Springs Branch, Cincinnati Creek, College Branch, Cove Creek, Dry Creek, Dye Creek, Ellis Branch, Evansville Creek, Fall Creek, Farmington Branch, the City of Fayetteville's water-supply and recreational lake, North Fork Farmington Branch, South Fork Farmington Branch, Fly Creek, Friendship Creek, Funhouser Branch, Goose Creek, Middle Fork Hamestring Creek, 3 iU its ✓ �tf��'� � �i� � %1 ip a= i ` 7iS�i ' la{l�ail le MIN .41 m KIM Elm SAM OMM ow QC wl, REMAIN, memp, 4 f mm i'm Irk ..

Approximate analyses were used to study those areas having a low development potential or minimal flood hazards. The scope and methods of study were proposed to, and agreed upon by, FEMA and Washington County. 2.2 Community Description Washington County is located in the northwestern corner of Arkansas, approximately 160 miles west-northwest of Little Rock. It is bordered by the unincorporated areas of Benton County to the north, Madison County to the east, Crawford County to the south, and the unincorporated areas of Adair County, Oklahoma, to the west. The City of Fayetteville is the county seat. Development within Washington County consists of a mixture of small single-family homes, duplexes, businesses, and chicken houses. Stream slopes in this mountainous region vary from approximately 10 to 50 feet per mile. Among the studied streams, the West Fork White River is the largest with a width of 100 to 150 feet, and the smallest is Moores Tributary, which is approximately 10 feet wide. The remaining streams are relatively small, and range from 20 to 30 feet in width. The stream banks are generally steep and covered with trees, brush, and other vegetation. Most of the notable development in the area is centered around Fayetteville and Springdale; small rural cities, such as Johnson, Lincoln, Prairie Grove, Greenland and West Fork are located in the drainage basins of the studied streams. The climate in the county is humid, with variable temperatures; average temperatures range from 36°F in January to 79°F in July. Summers are moderately long and hot. Winters are moderately short and cold. The average annual precipitation for the study area is approximately 42 inches (Reference 1). Precipitation is fairly uniformly distributed throughout the year, with heavier amounts in the spring and lesser amounts in the summer. Intense thunderstorms, however, occur in the summer and may produce large amounts of rain over a small area in a short period of time. Generally, major storms in the area are characterized by heavy rainfall from frontal -type storms. 2.3 Principal Flood Problems The intense rainfall usually associated with localized thunderstorms can produce major flooding within the county at any time during the year, especially during the spring and summer months. The West Fork White River is the only stream in the county with a gage to record stages (Reference 2). This gage is located near the left bank, on the downstream side of a pier for the old U.S. Route 71 bridge, approximately 1 mile south of Greenland. The period of record runs from 1946 to 1983. The following tabulation shows major floods recorded by this gage. Date April 3, 1957 Stage 13.54 (feet) Flow 27,700 May 6, 1960 14.50 34,700 April 22, 1973 13.20 25,600 November 24, 1973 14.30 33,300 May 13, 1982 12.90 17,900 The National Weather Service maintains one recording rain gage in Washington County, at Drake Field Airport, just south of Fayetteville. Development is taking place along the upstream of some streams within the unincorporated areas of the county. Sound floodplain management is required to prevent increased flood damage from increased runoff. Flood problems are scattered throughout the City of Fayetteville. High velocities and debris carried by floods cause considerable damage to streets and drainage structures in many parts of the city. Floodplains along some of the smaller tributaries widen for short distances and flood problems often occur in these areas because of encroachments by business or residential construction. Some flood losses have occurred along the West Fork White River during the large floods on that stream in 1927, 1943, 1945, and 1960. Damaging floods also occurred in 1966, 1968, 1970, 1976, and 1978. Small residential areas along Town Branch and its tributaries have suffered the brunt of flood damages. In the northern and western parts of the city, development has begun in areas of flood hazards. Sheetflow across residential property in hilly sections of the city has caused more inconvenience than damage. Two trailer parks are located in the floodplain and would be subject to heavier damage during the 100 -year flood. Past flood problems in the City of Johnson have not been severe. The most significant flooding problem has been the inundation of streets: Johnson Road by Clear Creek, and Main Street by Johnson Creek. The low-water bridge on Ball Street is flooded frequently. Generally, other flood problems have been widely scattered and usually restricted to a few structures in any given area; however, continued growth in Johnson, without careful consideration of potential flood losses could result in serious flood problems. There have been no major flood problems in the City of Springdale since the construction of the underground box conduits and channel improvements by the USACE, Tulsa District in the upper portion of Spring Creek. The West White River is the major flooding source within the City of West Fork; it flows toward the north, dividing the city. The western part of the city is located on a high cliff, and a major portion of the eastern part of the city is also on high ground. A portion of the city north of the Main Street bridge, however, does lie within the floodplain, and has future development potential. The floods of record occurred in 1960 and 1974, and both had an approximate recurrence interval of 25 years. There are a few tributaries to the West Fork White River that flow through the city; most of them, except Dye Creek, have small drainage areas and are not significantly affected by backwater from the river. Dye Creek flows through a small, thinly populated portion of West Fork and has a narrow floodplain. 2.4 Flood Protection Measures Within the unincorporated areas of Washington County, no major structural flood protection measures exist or are currently planned. In Fayetteville, some channel enlargements have been made on smaller streams, but the effects of these improvements have been largely offset by the continuing urbanization of the area. There are no significant flood protection measures within the City of Johnson. In the City of Springdale, the underground multiple concrete -box conduits constructed between Meadow Avenue and Johnson Avenue, and the channel improvements made between Old Missouri Road and Sanders Avenue by the USACE, Tulsa District have reduced the flood hazards from Spring Creek in populated areas. The only other flood protection measures for Springdale, and the City of West Fork, are the flash flood warnings issued by the National Weather Service on a regional basis. 3.0 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 which 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 which 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); 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 county. Information on the methods used to determine peak discharge -frequency relationships for the streams studied by detailed methods, compiled from the previously printed narratives for Washington, County, is shown below. The incorporated communities are listed in alphabetical order; methodologies are described for each community. For streams that flow through two or more communities, each methodology described applies only to that portion of the stream studied by detailed methods within that particular community. The Flood Insurance Study for the City of Fayetteville considered the following streams: Airport Branch, Cato Springs Branch, Clear Creek, Hamestring Creek, South Fork Hamestring Creek, Mud Creek, Mud Creek Tributary, Scull Creek, Sublet Creek, Tin Cup Creek, Town Branch, and the West Fork White River (Reference 3). In that study, discharge information for the West Fork White River were obtained from continuous stream -flow records collected at the USGS gage in Fayetteville; this period of record began in 1937. Discharges on the other streams were determined using unit hydrographs developed at various locations on these streams along with appropriate design storms. The design storms were developed from U.S. Weather Bureau Technical Paper Nos. 40 and 49 (References 4 and 5). The 500 -year discharges were obtained by extrapolating the curves obtained from the 10-, 50-, and 100 -year flood discharges. In some instances, flood routing of hydrographs was necessary to take into account storage upstream from constricted openings. Flows for the 10 -year floods were checked whenever possible against estimated floods that have occurred in recent years. The Flood Insurance Study for the City of Johnson considered the following streams: Clear Creek and Mud Creek (Reference 6). In that study, discharges for these streams were determined using unit hydrographs developed at various locations, along with appropriate design storms. The design storms were developed from U.S. Weather Bureau Technical Paper Nos. 40 and 49 (References 4 and 5). The 500 -year discharges were obtained by extrapolating the curves obtained from the 10-, 50-, and 100 -year flood discharges. In some instances, flood routing of hydrographs was necessary to take into account storage upstream from constricted openings. Flows for the 10 -year floods were checked whenever possible against estimated floods that have occurred in recent years. The Flood Insurance Study for the City of Springdale considered the following streams: Brush Creek Tributary, Spring Creek, and Tributaries 1, 2, 4, and 5 (Reference 7). In that study, peak discharges were determined at various locations along the streams. Regional drainage area -discharge -frequency relationships were developed for the 10-, 50-, and 100 -year floods through log -Pearson Type III frequency analyses of the systematically recorded peak -discharge data at USGS Gage Nos. 07047990, 07048600, 07049000, 07050500, 07195000, 07195200, and 07195800, located in northwestern Arkansas. The FREQFLO computer program was used for the frequency analysis of the recorded gage data (Reference 8). Historical flooding data were included in the analysis when available. The effects of outliers were also accounted. In the case of Gage Nos. 07047990, 07048600, 07049000, 07195200, and 07195800, a regional skew coefficient of -0.3 was used by the computer, because the period of record for these gages was less than 25 years. For Gage Nos. 07050500 and 07195000, the computer determined weighted skew coefficients using the computed skew based on the recorded data and the generalized map skew of -0.3. Using the results of the frequency analysis, drainage area -discharge curves were plotted on log -log paper for the 10-, 50-, and 100 -year floods. The discharge magnitudes for the designated frequency floods at different stream locations 11 were read from the curves. The 10-, 50-, and 100 -year discharge values were plotted on log -probability paper and extrapolated to obtain the 500 -year discharges. The Flood Insurance Study for the City of West Fork considered the West Fork White River (Reference 9). In that study, peak discharges were determined at the downstream limit of study. USGS Gage No. 07048000 is located on the West Fork White River at Greenland, approximately 6 miles downstream of West Fork. Recorded peak -discharge data were collected at the gage from 1945 through 1976. A log -Pearson Type III statistical frequency analysis of these data was made using the FREQFLO computer program (Reference 8). The program determined a weighted skew coefficient using the computed skew and a generalized map of skew coefficients obtained from USGS Bulletin 17B (Reference 8). No expected probability adjustment was made in the frequency distribution. In order to project the results of the frequency analysis at the gage to the designated location in the study area, a drainage area -peak discharge relationship was prepared using recorded peak -discharge data from USGS gages in northwest Arkansas that were judged to have similar basin characteristics. Mean values of high -peak flows from a contemporary period of records were plotted on log -log graph paper, from which the equation of the best -fit curve was determined. A relationship was developed between the drainage area and peak discharge to allow projection of discharges for selected frequency floods to the designated location in the study area. The drainage area -discharge relationship for northwest Arkansas took the following form: Qs/Qg = [As/Ag]o.8876 x As( -0.1005 Log Ac)/Age-0'°°5 Log Ag) in which Qg and Ag are the discharge and drainage area, respectively, at the gage, and Qs and As are the corresponding quantities at the designated site. The equation is applicable between drainage area limits of 0.6 and 600 square miles. •The drainage area at USGS Gage No. 07048000 is 83 square miles, and that at the study area is 62.2 square miles. During field surveying operations, a high-water mark was pointed out by a local resident as the highest in the previous five years. Discharge records at the gage from 1972 through 1976 indicated that the highest discharge, 33,000 cubic feet per second (cfs), was recorded on November 24, 1974. This discharge, when projected to the study area using the aforementioned equation, yielded a value of 28,708 cfs. This 1974 flood discharge was used to calibrate channel roughness coefficients for the hydraulic analysis of the West Fork White River in the City of West Fork. In this countywide study, discharges for the streams studied by detailed methods within Washington County, except for the West Fork White River, were developed using the USACE HEC-1 program and National Weather Service Technical Paper Nos. 40 and 49 (References 4 and 5). The 100 -year discharge for the West Fork White River as determined using a discharge -frequency curve plotted from gage data collected at the USGS gage in Greenland from 1946 to 1983. Regression equations were used to determine the peak discharge for Main Ditch in the Town of Tontitown. 12 A summary of the drainage area -peak discharge relationships for the streams studied by detailed methods is shown in Table 2. 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. Information on the methods used to determine water -surface elevations for the streams studied by detailed methods, compiled from the previously printed narratives for • Washington County, is shown below. Except where noted, water -surface elevations for floods of the selected recurrence intervals were determined using the USACE HEC-2 step -backwater computer program (Reference 10). The incorporated communities and the • unincorporated areas of the county are listed in alphabetical order; methodologies used to develop cross sections, starting water -surface elevations, and channel roughness factors (Manning's "n") are described for each community. For streams that flow through two or more communities, each methodology described applies only to that portion of the stream studied by detailed methods within that particular community. The Flood Insurance Study for the City of Fayetteville considered the following streams: Airport Branch, Cato Springs Branch, Clear Creek, Hamestring Creek, South Fork Hamestring Creek, Mud Creek, Mud Creek Tributary, Scull Creek, Sublet Creek, Tin Cup Creek, Town Branch, and the West Fork White River (Reference 3). In that study, cross sections were obtained from new field surveys, or from surveys previously made for other studies in the community. All waterway openings and invert elevations through bridges and culverts were obtained during the field surveys. Water -surface elevations were determined using either the USACE HEC-2 step -backwater computer program or the USACE "Multiple Backwater Profiles with Provisions for Bridge and Weir Losses" computer program (References 10 and 11). Channel roughness factors (Manning's "n") used in the hydraulic analyses for the West Fork White River had been determined previously by the USACE from known discharges and profiles. Roughness factors for the smaller streams were estimated from field conditions. Although clogging of channels and bridge openings by debris during floods is a serious problem, for the purposes of this study it was assumed that clogging of openings and waterways would not affect the water -surface elevations significantly, and that all bridge structures would remains intact. • The Flood Insurance Study for the City of Johnson considered the following streams: Clear Creek and Mud Creek (Reference 6). In that study, cross section data were obtained from field surveys. All bridges and culverts were field surveyed to obtain elevation data and structural geometry. Cross sections were located at close intervals upstream and downstream of bridges and culverts in order to compute the significant backwater effects of these structures. 13 Inen N N 7 0 -e in O '0 N .4 ��Q111 -- N O U N Y ayq p O� 8 O 8 M Y O N 'D 'O '0 OS.

Channel roughness factors (Manning's "n") used in the hydraulic computations were assigned on the basis of field inspections. For Johns Creek, approximate flood elevations were developed using depths determined from slope/area computations using areas and slopes from topographic maps and discharges from discharge -area curves (Reference 12). These depths were projected onto the topographic maps and checked by field inspection. In that study, cross sections were field surveyed at appropriate intervals, and above and below bridges and culverts in order to determine significant backwater effects. Elevation data and structural geometry of all bridges, culverts, and other hydraulic structures were obtained from field surveys or from as -built plans provided by highway departments. Details of the channel improvements and the concrete -box conduits on Spring Creek were obtained from as -built plans furnished by the USACE Tulsa District. Topographic details of the ground and locations of buildings above the concrete -box conduits were obtained through field surveys. The computations were started downstream of hydraulic structures located near the downstream limit of detailed study in order to include the backwater effects of these structures. For Spring Creek, Brush Creek Tributary, and Tributary 4, computations were started using the slope/area method of the HEC-2 program, after the initial estimates of energy slopes were made through preliminary HEC-2 runs of the first few cross sections. For Tributaries 1 and 2, which flow into Spring Creek, starting water -surface elevations were taken from the flood profiles for Spring Creek at each confluence. For Tributary 5, which flows into Tributary 4, starting elevations were taken from the flood profile for Tributary 4 at the confluence. For Spring Creek, the water -surface profiles for floods of the selected recurrence intervals were computed up to the downstream side of the concrete -box conduits. Then, based on the condition of flow as determined by the water -surface elevations downstream of the box, flow through the box conduit was calculated separately, using either the orifice -flow equation or the nomographs for concrete boxes (References 10 and 13). Flow over Emma Avenue at the box conduits was calculated using the WEIRFLO computer program (Reference 14). Water -surface elevations upstream of the box conduits were determined using the procedures mentioned, as appropriate. These elevations were then entered as known water -surface elevations at the stream cross sections upstream of the box; the HEC-2 runs were then continued to the upstream limit of detailed study. Channel roughness factors (Manning's "n") used in the hydraulic computations were assigned on the basis of engineering judgment and field observation of the stream and floodplain areas. The Flood Insurance Study for the City of West Fork considered the West Fork White River (Reference 9). EL In that study, cross sections were obtained through field survey. All bridges and culverts were field surveyed to obtain elevation data and structural geometry. Cross sections were located at close intervals upstream and downstream of bridges and culverts in order to compute their significant backwater effects. Water -surface calculations were started at a location immediately downstream of the corporate limits. The starting water -surface elevation was determined using a method of successive iteration of changing energy slopes between the starting cross section and a downstream section selected for the purpose. Dr. C. K. Sarkar developed the method while working as the Project Engineer for Dalton, Dalton, Little, and Newport on a FEMA Flood Insurance Study project in Maryland. The method was recognized by the USACE Hydrologic Engineering Center as a significant improvement over the slope/area method used in the HEC-2 computer program. Channel roughness factors (Manning's "n") used in the hydraulic computations were assigned on the basis of field observation. A high-water mark for the November 1974 flood was available from a local resident. This flood at the study location was estimated from the recorded discharge at USGS Gage No. 07048000 (see Section 3.1). The initial estimates of "n" values were slightly adjusted to match the high-water mark. In this countywide study, cross sections of the backwater analyses of streams within Washington County were field surveyed. Starting water -surface elevations were determined using the slope/area method. Channel roughness factors (Manning's "n") were assigned on the basis of engineering judgment and field inspection of the streams and overbank floodplain areas. The starting water -surface elevation for Main Ditch in the Town of Tontitown was determined using the slope/area method. For this countywide Flood Insurance Study, 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 Flood Insurance Rate Map (Exhibit 2). Flood profiles were drawn showing computed water -surface elevations for floods of the selected recurrence intervals. Table 3, "Summary of Roughness Coefficients," shows the ranges of the channel and overbank roughness factors (Manning's "n") used in the hydraulic computations for the streams studied by detailed methods. The hydraulic analyses for this study were based on unobstructed flow. The flood elevations shown on the profiles are thus considered valid only if hydraulic structures remain unobstructed, operate properly, and do not fail. All elevations are referenced to the National Geodetic Vertical Datum of 1929 (NGVD). Elevation reference marks used in this study are shown on the maps; the descriptions of the marks are presented in Elevation Reference Marks (Exhibit 3). 19 Table 3.

The NFIP encourages State and local governments to adopt sound floodplain management programs. Therefore, each Flood Insurance Study provides 100 -year flood elevations and delineations of the 100- and 500 -year floodplain boundaries and 100 -year floodway to assist communities in developing floodplain management measures. 4.1 Floodplain Boundaries To provide a national standard without regional discrimination, the 1 -percent annual chance (100 -year) flood has been adopted by FEMA as the base flood for floodplain management purposes. The 0.2 -percent annual chance (500 -year) flood is employed to indicate additional areas of flood risk in the community. For each stream studied by • detailed methods, the 100- and 500 -year floodplain boundaries have been delineated using the flood elevations determined at each cross section. Between cross sections, the boundaries were interpolated using topographic maps at a scale of 1:24,000 with a contour intervals of 10 and 20 feet (Reference 12). For the streams studied by approximate methods, 100 -year floodplain boundaries were delineated using the Flood Hazard Boundary Maps for the City of Elkins, the City of Greenland, and the unincorporated areas of Washington County (References 15, 16 and 17); and the previously printed Flood Insurance Studies for the City of Fayetteville, the City of Johnson, the City of Springdale, the City of West Fork, the Town of Tontitown, the City of Winslow, the Town of Elm Springs, and the City of Farmington (References 3, 6, 7, 9, 18, 19, 20, and 21). The 100- and 500 -year floodplain boundaries are shown on the Flood Insurance Rate Map (Exhibit 2). On this map, the 100 -year floodplain boundary corresponds to the boundary of the areas of special flood hazards (Zones A and AE); and the 500 -year floodplain boundary corresponds to the boundary of areas of moderate flood hazards. In cases where the 100- and 500 -year floodplain boundaries are close together, only the 100 -year 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. 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 100 -year 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 100 -year 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 floodway studies. 21 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 (Table 4). The computed floodways are shown on the flood Insurance Rate Map (Exhibit 2). In cases where the floodway and 100 -year floodplain boundaries are either close together or collinear, only the floodway boundary is shown. For Spring Creek, the floodway width extends beyond the county boundary. The area between the floodway and 100 -year 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 100 - year flood more than 1.0 foot at any point. Typical relationships between the floodway and the floodway fringe and their significance to floodplain development are shown in Figure 2.

Floodway Schematic Near the mouths of streams studied in detail, floodway computations are made without regard to flood elevations on the receiving water body. Therefore, "Without Floodway" elevations presented in Table 4 for certain downstream cross sections of Tributary 2 are lower than the regulatory flood elevations in that area, which must take into account the 100 -year flooding due to backwater for other sources. 22 . o'0c OO 0000 PO • . . . . . . . . . . . . 00 0000.-4 ccOc c.• U z z O Q . . . • . • • • . . • • . 0 ODd N1 N1-00O.d OO P1n00 Nn Q N N NNN1.1r1 P1 01M fn en NN ll Ii. z .-1 ..1 ------ rl ..+--- .+ .N N U FQ 3 n In In .. v..., vi v. uU o -. no vdi 0 • • y.

These zones are as follows: FE1i[�:1 Zone A is the flood insurance rate zone that corresponds to the 100 -year floodplains that are determined in the Flood Insurance Study by approximate methods. Because detailed hydraulic analyses are not performed for such areas, no base (100 -year) flood elevations (BFEs) or depths • are shown within this zone. Zone AE 0 Zone AE is the flood insurance rate zone that corresponds to the 100 -year floodplains that are determined in the Flood Insurance Study by detailed methods. Whole -foot BFEs 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 100 -year shallow flooding (usually areas of ponding) where average depths are between 1 and 3 feet. Whole -foot BFEs derived from the detailed hydraulic analyses are shown at selected intervals within this zone. Zone AO Zone AO is the flood insurance rate zone that corresponds to the areas of 100 -year shallow flooding (usually sheet flow on sloping terrain) where average depths are between 1 and 3 feet. Average whole -foot depths derived from the detailed hydraulic analyses are shown within this zone. Zone A99 Zone A99 is the flood insurance rate zone that corresponds to areas of the 100 -year floodplain that will be protected by a Federal flood protection system where construction has reached specified statutory milestones. No BFEs or depths are shown within this zone. Zone V Zone V is the flood insurance rate zone that corresponds to the 100 -year coastal floodplains that have additional hazards associated with storm waves. Because approximate hydraulic analyses are performed for such areas, no BFEs are shown within this zone. Zone VE Zone VE is the flood insurance rate zone that corresponds to the 100 -year coastal floodplains that have additional hazards associated with storm waves. Whole -foot BFEs derived from the detailed hydraulic analyses are shown at selected intervals within this zone. 33 Zone X Zone X is the flood insurance rate zone that corresponds to areas outside the 500 -year floodplain, areas within the 500 -year floodplain, areas of 100 -year flooding where average depths are less than 1 foot, areas of 100 -year flooding where the contributing drainage area is less than 1 square mile, and areas protected from the 100 -year flood by levees. No BFEs or depths are shown within this zone. Zone D Zone D is the flood insurance rate zone that corresponds to unstudied areas where flood hazards are undetermined, but possible. The Flood Insurance Rate Map 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 100 -year floodplains that were studied by detailed methods, shows selected whole -foot BFEs 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 100 - and 500 -year floodplains. Floodways and the locations of selected cross sections used in the hydraulic analyses and floodway computations are shown where applicable. The current Flood Insurance Rate Map represents flooding information for the entire geographic area of Washington County, and includes the flood hazard information that was presented separately, on Flood Boundary and Floodway Maps, in the previously printed Flood Insurance Studies for this area. Previously, separate Flood Insurance Rate Maps were prepared for the Town of Elm Springs and Tontitown, and the Cities of Farmington, Fayetteville, Johnson, Springdale, West Fork, and Winslow. Historical data relating to the maps prepared for each community are presented in Table 5, "Community Map History." Flood Insurance Studies have been prepared for the unincorporated areas of Madison County, Arkansas, and Adair County, Oklahoma (References 22 and 23). The results of this study are in exact agreement with the results of those studies. Flood Insurance Studies have been prepared for Benton County and Incorporated Areas, and Crawford County and Incorporated Areas (References 24 and 25). The results of those studies are in exact agreement with the results of this study. 34 I V, V, co a' a 0' a' a a as a a a — rl --4 - rl —4 . . . . . . . o a0 ao a aD y N rl a0 - co w= Y Y Y Y Y is is •• LL H ?

Future revisions may be made that do not result in the republishing of the Flood Insurance Study report. To assure that any user is aware of all revisions, it is advisable to contact the community repository of flood hazard data located at FEMA, Mitigation Division, Federal Regional Center, Room 206, 800 North Loop 288, Denton, Texas 76201-3698. 10.1 First Revision The results of more detailed hydrologic and hydraulic analyses and more detailed topographic information to reflect existing watershed conditions along White River from approximately 2.8 miles downstream of Highway 74 (River Mile 691.38) to approximately 0.8 mile upstream of East First Avenue (River Mile 698.04) and along Middle Fork White River from approximately 0.22 mile upstream of Highway 16 (River Mile 0.99) to just downstream of Harris Drive (Extended) (River Mile 2.28), were incorporated into this Flood Insurance Study. The revision request was submitted by the Honorable Barbara King, Mayor City of Elkins, Arkansas, with her •letter dated March 16, 1995. As a result of more detailed hydrologic and hydraulic analyses and more detailed topographic information, the elevations of a flood having 1 -percent chance of being equaled or exceeded in any given year (base flood) have been determined for the study areas. Floodway has been established for both reaches. Floodplain boundaries associated with the base flood along White River and Middle Fork White River have been revised. The revised hydrologic and hydraulic analyses for this revision were developed by the USACE, Little Rock District, and presented in their report entitled, "Elkins, Arkansas, White River and Middle Fork, Flood Hazard Study," (Reference 26). The hydrologic analysis for the White River was performed utilizing the USACE HEC-1 Flood Hydrograph computer program (Reference 27). This HEC-1 model includes the Middle Fork White River. The White River basin was divided into four subbasins above the City of Fayetteville Gage Station. Basin characteristics required by the model were determined from a 7.5 -minute quadrangle map and Modified Fort Worth Method curves developed by the USACE, Little Rock District. This model was calibrated to reproduce the May 1990 gage 'flood hydrograph at the City of Fayetteville gage. The results of the hydrologic computations are shown in Table 2, "Summary of Discharges." The hydraulic analysis for the revised reaches utilized the USACE HEC-2 step -backwater computer program (Reference 28). The HEC-2 analyses, dated September 20, 1995, for the White River, and August 26, 1992, for Middle Fork White River incorporated the developed discharges and more detailed topographic information. The channel roughness factors (Manning's "n") range from 0.03 to 0.035 along the White River and from 0.030 to 0.055 along the Middle Fork White River. The overbanks roughness "n" value, ranges from 0.045 to 0.12 along the White River and from 0.075 to 0.16 along the Middle Fork White River. Cross-section information was obtained by field surveys completed December 1991. The floodplain and floodway boundaries were located at each cross section based on the computed water -surface elevations. Between cross sections, the floodplain and floodway boundaries were interpolated using topographic maps at a Scale of 1" = 500' and a 20 -foot contour interval. The floodway along White River and Middle Fork White River was computed based on equal conveyance reduction, and adjusted until the allowable increase in stage was achieved. 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 4, "Floodway Data." 0 u■■o■■■■■■■u■un■n■\Iq■■nnn■ ■■ ■ ■ u n ■ ■ ■ ■ ■n■■■■■n■ulln p p • •: n:l■■®■::■ '®�I:C�i1�lulaai■■■:1■■:IC:m.1�■min:n®■ml■I:I:mm■©■i■■■■■■.....nll.. ■ n /■■■■■■■n■■■n■■■n■nu■n■■■n■■■■/■■/n■ ■■n■n n■■n■■■■■.■��i�®:�m00,�1�:�11e1:■�illeii•••u.nn■■■■■■n■■■■■■■■■■■::■■u■nilu In .'■■n■®nM■1.n■ ■■n a9■®E�=.sse..e9 :_B;E: paamml:Im1I nn::mn�9e®E®s N:m®ImIIaNINNIa�a�,■®In■■l■j_'■■/n■■■n■nn■nu.n■ ■ . ■■Ilu Il:al:::amLLaNNai�:N:aa:i=imm1®m■■■■■q__■n--■■■/ll■®11:1■llll:lllll:l■■11■■ u■■■nn■n■■■/n■■■■■//■■■■■■/■■■■■■■■■■11■■ n _ .. pn■pn■■■■■■■p■■■■/n■nna�lgl\lu■nn■ • ' ®mIl aaaNlaal■■■n/■■■■■■■■■n■/■■■■n■■11■■ ■n■■■■■■■■■/■■■/■n■■11■■ ■■aa:aam:amklmaam1N:::®a�■ //■■ n■nn■ Eqlm_lOlmllmlCllm'lll�l'■qn■■Iin ■■■n■■11■■ �imC�m®Illlllll��®�il ®1®�1�"' ®1'm■■n�uIs 1 _ ■■Nn■nn•n p■ •L•J�1SSrtYIC1✓Li�l��3]■n■/11■■ nP\■■/■■■/■■ glln®�/ivaiinn ■ ■w Him a®��p■p■.■■■/■■n■■11■/ ■retrl�.n■ ■� \ ®MEN altaia' i&\ 1®�a■.��■� ■■■nnu■nn■■nn■■■::a1aN:Nala11'el: n ■■11■■n■■■■/■n■■■n■/11n Fenn=a■ aal�a_al • '__:11a1®1�1n■■n■■mnm:mm:■■■n■■■/■nN■n■r13/ ■■n■■■■■■:::N::1��N - ■:al®NIIIIa111®► 911!®mmCC am°� NII MEN_:NN� �"!!r'I :�iva . ■ t n■■■■■ ■u■■■ om��m�N�:m��il.�idaq.

D. METHODS OF REDUCING FLOOD LOSS In order to accomplish its purposes, this ordinance uses the following methods: Restricting or prohibiting uses that are dangerous to health, safety or property due to water or erosion hazards in times of flood, or cause excessive increases in flood heights or velocities; Requiring that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction; Controlling the alteration of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation of flood waters; 4. Controlling filling, grading, dredging and other development which may increase flood damage; 5. Preventing or regulating the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards to other lands. E.

Substantial improvement. Any repair, reconstruction, or improvement of a structure, the cost of which equals or exceeds 50% of the market value of the structure either: A. before the improvement or repair is started; or B. if the structure has been damaged, and is being restored, before the damage occurred. For the purposes of this definition "substantial improvement" is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure. The term does not, however, include either: A. any project for improvement of a structure to comply with existing state or local health, sanitary, or safety code specifications which are solely necessary to assure safe living conditions; or B. any alteration of a structure listed on the National Register of Historic Places or a state inventory of Historic Places. Variance. A grant of relief to a person from the requirements of this ordinance when specific enforcement would result in unnecessary hardship. A variance, therefore, permits construction or development in a manner otherwise prohibited by this ordinance. (For full requirements see Section 60.6 of the National Flood Insurance Program regulations.) Violation. The failure of a structure or other development to be fully compliant with the community's floodplain management regulations. A structure or other development without the elevation certificate, other certifications, or other evidence of compliance required in this chapter is presumed to be in violation until such time as that documentation is provided. Water surface elevation. The height, in relation to the National Goedetic Vertical Datum (NGVD) of 1929 (or other datum where specified) of floods of various magnitudes and frequencies in the floodplains of coastal or riverine areas. F. GENERAL PROVISIONS This chapter shall apply to all areas of special flood hazards and areas of flood - related erosion hazards within the jurisdiction of the city. 2. The areas of special flood hazards and areas of flood -related erosion hazards identified by the Federal Emergency Management Agency or the Federal Insurance Administration in a scientific and engineering report entitled "Flood Insurance Study, Washington County, Arkansas and Incorporated Areas" dated September 18, 1991, with accompanying Flood Insurance Rate Maps, both of which may from time to time hereafter be amended and updated by FEMA, are hereby adopted by reference and made a part of this code as if set out in full herein. This Flood Insurance Study is the minimum area of applicability of this chapter and may be supplemented by studies for other areas which allow implementation of this chapter and which are recommended to the council by the Floodplain Administrator. 3. No structure or land shall hereafter be constructed, located, extended, converted or altered without full compliance with the terms of this chapter and other applicable 9 regulations. Violations of the provisions of this chapter by failure to comply with any of its requirements (including violations of conditions and safeguards established in connection with conditions) shall constitute a misdemeanor. Nothing herein shall prevent the city from taking such lawful action as is necessary to prevent or remedy any violation. 4. This chapter is not intended to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions. However, where this chapter and any other code, ordinance, easement, covenant, or deed restriction conflict or overlap, whichever imposes the more restrictive restrictions shall prevail. 5. In the interpretation and application of this chapter, all provisions shall be: a. Considered as minimum requirements; b. Liberally construed in favor of the governing body; and c. Deemed neither to limit nor repeal any other powers granted under state statutes. 6. The degree of flood protection required by this chapter is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. Larger floods can and will occur on rare occasions. Flood heights may be increased by man-made or natural causes. This chapter does not imply that land outside the areas of special flood hazards, areas of flood -related erosion hazards, or uses permitted within such areas will be free from flooding or flood damages. This chapter shall not create liability on the part of the city, any officer or employee thereof, or the Federal Insurance Administration, for any flood damages that result from reliance on this chapter or any administrative decision lawfully made thereunder. G. ADMINISTRATION A Floodplain Development Permit shall be obtained before obtaining a Building Permit and prior to any construction or development within any area of special flood hazards or area of flood -related erosion hazards established in section F (2). An application for a Floodplain Development Permit shall be made on forms furnished by the Floodplain Administrator and may include, but not be limited to: plans in duplicate drawn to scale showing the nature, location, dimensions, and elevation of the area in question; existing or proposed structures, fill, storage of materials, drainage facilities; and the location of same. Specifically, the following information is required: 10 a. Proposed elevation in relation to mean sea level, of the lowest floor (including basement) of all structures; b. Proposed elevation in relation to mean sea level to which any structure shall be floodproofed; c. All appropriate certifications listed in section G(3)(a)(2) of this chapter; and d. Description of the extent to which a watercourse will be altered or relocated as a result of proposed development. 2. The Floodplain Administrator shall be designated by the Mayor and appointed to administer and implement this chapter by granting or denying Floodplain Development Permits in compliance with its provisions. Approval or denial of a Development Permit shall be based on all the provisions of this ordinance and the following relevant factors: a. The danger to life and property due to flooding or erosion damage; b. The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner; c. The danger that materials may be swept onto other lands to the injury of others; d. The compatibility of the proposed use with existing and anticipated development; e. The safety of access to the property in times of flood for ordinary and emergency vehicles; f. The costs of providing governmental services during and after flood conditions including maintenance and repair of streets and bridges, and public utilities and facilities such as sewer, gas, electrical and water systems; g. The expected heights, velocity, duration, rate of rise and sediment transport of the flood waters expected at the site; h. The necessity to the facility of a waterfront location, where applicable; I. The availability of alternative locations, not subject to flooding or erosion 11 damage, for the proposed use; The relationship of the proposed use to the General Plan 2010. 3. The duties and responsibilities of the Floodplain Administrator, as related to this chapter, shall include, but not be limited to: a. Permit Review 1) Review all Floodplain Development Permits to determine that the permit requirements of this chapter have been satisfied; ii) All other required state and federal permits have been obtained from those Federal, State, or local governmental agencies (including Section 404 of the Federal Water Pollution Control Act of 1972, 33 U.S.C. 1334) from which prior approval is required; iii) The site is reasonably safe from flooding; iv) The proposed development does not adversely affect the carrying capacity of areas where base flood elevations have been determined but the floodway has not been designated on the FIRM. For purposes of this chapter, "adversely affects" means that the cumulative effect of the proposed development when combined with all other existing and anticipated development will not increase the water surface elevation of the base flood more than one foot at any point. However, under the provisions of 44 CFR Chapter 1, Section 65.12, of the National Flood Insurance Program regulations, a community may approve certain development in Zones Al -30, AE, AH, on the community's FIRM which increases the water surface elevation of the base flood by more than one foot, provided that the community first applies for a conditional FIRM revision through FEMA. b. When base flood elevation data has not been provided in compliance with section (F)(2), the Floodplain Administrator shall obtain, review, and reasonably utilize any base flood elevation and floodway data available from a federal, state or other source, in order to administer this section. Any such information shall be submitted to the Council for adoption. c. Whenever a watercourse is to be altered or relocated, the Floodplain Administrator shall: 12 I) Notify adjacent communities and the Arkansas Soil and Water Conservation Commission prior to the alteration or relocation of a watercourse, and submit evidence of the notification to the Federal Emergency Management Agency; ii) Require that the flood carrying capacity of the altered or relocated portion of the watercourse is maintained. d. Secure and maintain for public inspection and availability the certifications, appeals and variances identified in section G(l) and section I. e. Make interpretations where needed as to the exact location of the boundaries of the areas of special flood hazards or areas of flood -related erosion hazards (for example, where there appears to be a conflict between a mapped boundary and actual field conditions). The person contesting the location of the boundary shall be give a reasonable opportunity to appeal the interpretation as provided in section I. H. PROVISIONS FOR FLOOD HAZARD REDUCTION In all areas of special flood hazards the following standards shall apply: 1. Anchoring a. All new construction and substantial improvements shall be anchored to prevent flotation, collapse or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy. b. All manufactured homes shall meet the anchoring standards of section (H)(6). 2. Construction materials and methods a. All new construction and substantial improvements shall be constructed with materials and utility equipment resistant to flood damage. b. All new construction and substantial improvements shall be constructed using methods and practices that minimize or resist flood damage. c. All new construction and substantial improvements shall be constructed with electrical, heating, ventilation, plumbing and air conditioning equipment and other service facilities that are designed and/or located so 13 as to prevent water from entering or accumulating within the components during conditions of flooding. Elevation and floodproofing a. New construction and substantial improvement of structure shall have the lowest floor, including basement, elevated two feet above the base flood elevation specified in feet on the FIRM, or at least 2 feet above the highest adjacent grade if no depth number is specified. Nonresidential structures shall meet the standards in section H(3)(b). Upon the completion of the structure, the elevation of the lowest floor including basement shall be certified by a registered professional engineer to be properly elevated. The certification or verification shall be provided to the Floodplain Administrator. On With On Piles. Slab Basenent Piers, or Colunns Base Re Ference Re Ference ��1 Flood Level Level J\ Elevation -' Base �Re Ference , Flood Flood Adjacent Level , Elevation Gradeli Elevntion Elevations should be neasured at the top of the reference level floor. b. Nonresidential construction shall either be elevated in conformance with section H(3)(a) or (c) or together with attendant utility and sanitary facilities: I) Be floodproofed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water; ii) Have structural components capable of resisting hydrostatic and hydrodynamic loads and effects of buoyancy; and iii) Be certified by a registered professional engineer or architect that the standards of this subsection are satisfied. The certification or 14 verification shall be provided to the Floodplain Administrator. Require, for all new construction and substantial improvements, that fully enclosed areas below the lowest floor that area subject to flooding shall be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of flood waters. Designs for meeting this requirement must either be certified by a registered professional engineer or architect or meet or exceed the following minimum criteria: I) Either a minimum of 2 openings having a total net area of not less than 1 square inch for every square foot of enclosed area subject to flooding shall be provided. The bottom of all openings shall be no higher than 1 foot above grade. Openings may be equipped with screens, louvers, valves or other coverings or devices provided that they permit the automatic entry and exit of flood waters; or ii) Be certified to comply with floodproofing standards approved by the Federal Insurance Administration. 1 Ft. na> iuu sq. uncnes total d. Manufactured homes shall also meet the standards in this section. 4. Standards for utilities a. All new and replacement water supply and sanitary sewage systems shall be designed to minimize or eliminate infiltration of flood waters into the system and discharge from systems into flood waters. b. On -site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. 15 Don't Do This Standards for subdivisions Applications for Preliminary, Final, and/or Concurrent Plat approval shall contain the requirements identified in sections 159.12, 159.13, and/or 159.14 (content and form) of the Fayetteville Municipal Code in addition to the following: a. Identify the special flood hazards areas, including delineation of floodways, and the elevation of the base flood. b. All Final Plats shall provide the elevation of proposed structure(s) and pads. If the site is filled above the base flood, the final pad elevation shall be verified by a registered professional engineer or surveyor and provided to the Floodplain Administrator. c. All proposals shall be consistent with the need to minimize flood damage. d. All proposals shall have public utilities and facilities such as sewer, gas, electrical, and water systems located and constructed to minimize flood damage. e. All proposals shall provide adequate drainage to reduce exposure to flood hazards. f. To the extent practicable, lot boundaries shall be made to coincide with natural and pre-existing man-made drainage ways within subdivisions to avoid the creation of lots that can be built upon only by altering such drainage ways. Flood Hazard Area 16 Do This Flood Hazard Area g. Any lot platted so that a portion of the lot lies in a special flood hazard area shall contain a minimum of 6,000 square feet of buildable area, including setbacks, outside the special flood hazard area, or if it contains less than 6000 square feet of buildable area, it shall be platted to contain a minimum of one acre. Any lot platted so that the entire lot lies in a special flood hazard area shall contain a minimum of one acre. Buildable Area 6,000 Sq. Ft. Min. Flood Hazard Area h. For subdivisions partially located in special flood hazard areas, minimum lot area requirements may be waived by the Director to allow the platting of lots to be clustered outside the special flood hazard area, the density permitted for the zoning district to be averaged over the entire parcel, provided a permanent conservation easement is granted to the City, a land trust, or the property owners association to ensure that the area of special flood hazard will remain undeveloped. 17 I. In any area that is located outside a special flood hazard area but where a stream is located, no building or fill may be located within a distance of the stream bank equal to five times the width of the stream at the top of the bank or 20 feet on each side, whichever is greater. Base flood elevation, data shall be generated for subdivision proposals and other proposed development including the placement of manufactured home parks and subdivisions which are greater than 50 lots or 5 acres, whichever is lesser, if not otherwise pursuant to F(2) or G(3)(b). Standards for manufactured homes All new and replacement manufactured homes and additions to manufactured homes shall be constructed in the following manner: a. Be elevated so that the lowest floor is two feet above the base flood elevation; and b. All manufactured homes shall be anchored to resist flotation, collapse, or lateral movement by providing over -the -top and frame ties to ground anchors. Specific requirements include: I) Over -the -top ties be provided at each of the 4 corners of the manufactured homes, with 2 additional ties per side at intermediate locations, with manufactured homes less than 50 feet long requiring 1 additional tie per side; ii) Frame ties be provided at each corner of the home with 5 additional ties per side at intermediate points, with manufactured homes less than 50 feet long requiring 4 additional ties per side; E iii) All components of the anchoring system be capable of carrying a force of 4,800 pounds; and iv) Any additions to the manufactured homes be similarly anchored. Floodways a. Located within areas of special flood hazard established in section F(2) are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of flood waters which carry debris, potential projectiles, and erosion potential, the following provisions shall apply: Prohibit encroachments, including fill, new construction, substantial improvements, and other development unless certification by a registered professional engineer or architect is provided demonstrating that encroachment shall not result in any increase in flood levels during the occurrence of the base flood discharge. b. If section (H)(7)(a) is satisfied, all new construction and substantial improvement shall comply with all other applicable flood hazard reduction provisions of section H. c. Under the provisions of 44 CFR Chapter 1, Section 65.12, of the National Flood Insurance Regulations, a community may permit encroachments within the adopted regulatory floodway that would result in an increase in base flood elevations, provided that the community first applies for a conditional FIRM and floodway revision through FEMA. 8. Standards for areas of shallow flooding (AO/AH Zones) Located within the areas of special flood hazard established in F(2), are areas designated as shallow flooding. These areas have special flood hazards associated with base flood depths of I to 3 feet where a clearly defined channel does not exist and where the path of flooding is unpredictable and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow; therefore, the following provisions apply: a. All new construction and substantial improvements of residential structures have the lowest floor (including basement) elevated above the highest adjacent grade at least as high as the depth number specified on the FIRM (at least two feet if no depth number is specified). 19 b. All new construction and substantial improvements of non-residential structures: 1) have the lowest floor (including basement) elevated above the highest adjacent grade at least as high as the depth number specified on the FIRM (at least two feet if no depth number is specified), ii) together with attendant utility and sanitary facilities be designed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads of effects of buoyancy. c. A registered professional engineer or architect shall submit a certification to the Floodplain Administrator that the standards of this section, as proposed in G(1)(a), are satisfied. d. Require adequate drainage paths around structures on slopes to guide flood waters around and away from proposed structures. I. APPEALS AND VARIANCES The Planning Commission shall hear and decide on requests for variances from the requirements of this ordinance. Any person or persons aggrieved by the decision of the Planning Commission regarding an appeal for a variance may appeal such a decision in the courts of competent jurisdiction. 1. The Planning Commission shall hear and decide on an appeal only when it is alleged there is an error in any requirement, decision, or determination made by the Floodplain Administrator in the enforcement or administration of this chapter. In passing upon such applications, the Planning Commission shall consider all technical evaluations, all relevant factors, and standards specified in other sections of this ordinance. Variances may be issued for the reconstruction, rehabilitation or restoration of structures listed in the National Register of Historic Places, without regard to the procedures identified in the remainder of this ordinance. Variances may only be issued for the repair or rehabilitation will not preclude the structure's continued designation as a historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure. 20 4. Generally, variances may be issued for new construction and substantial improvements to be erected on a lot acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing items (a) through (j) of section G(2) have been fully considered. As the lot size increases beyond'/2 acre, the technical justification required for issuing the variance increases. 5. Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result. 6. Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief. Floodplain variances shall only be issued if: a. there are exceptional or extraordinary circumstances or conditions applicable to the property involved or to the intended use of the property, which do not apply generally to other property in the same flood zone; b. a determination that failure to grant the variance would result in exceptional hardship to the applicant; c. a determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisances. cause fraud on or victimization of the public, or conflict with the Municipal Code. 8. Variances may be issued for new construction and substantial improvements and for other development necessary for the conduct of a functionally dependent use provided that the provisions of section G(2) are satisfied and that the structure or other development is protected by methods that minimize flood damages during the base flood and create no additional threats to public safety. Upon consideration of the factors in this Section and the purposes of this ordinance, the Planning Commission may impose conditions to the granting of floodplain variances as it deems necessary to further the purposes of this ordinance. 10. Any applicant to whom a variance is granted shall be given written notice that the structure will be permitted to be built with a lowest floor elevation below the regulatory flood elevation surcharge and that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest floor elevation. A copy of the notice shall be recorded by the Floodplain Administrator 21 in the office of the Washington County Clerk and shall be recorded in a manner so that it appears in the chain of title of the affected parcel of land. 11. The Floodplain Administrator shall maintain the records of all appeal actions and report any variances to the Federal Insurance Administration upon request. 22 O O 0 O OO O 0 C fU CD 0 Im N O T a ti ro a n n a Z >'1 o 2 p 's1 0 C O - A CrJ O w z 1? w m [yiy d 3 m A 1 C n m o m a 3 as C m o CDfl �d I,.d O. o 'O v o oT . o3I a eo 5 '- d F w' 3 W A N U N a ad a O m a A o Uflro 2.
