KANSAS 1.0 INTRODUCTION 1.1 Purpose of Study This Flood Insurance Study investigates the existence and severity of flood hazards in the City of Salina, Saline County. Kansas, 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 their efforts to promote sound flood plain management. Minimum flood plain management requirements for participation in the National Flood Insurance Program are set forth in the Code of Federal Regulations at 44 CFR, 60.3. In some states or communities, flood plain 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. The hydrologic and hydraulic analyses for this study were performed by Bucher, Willis & Ratliff. Consulting Engineers, Planners and Architects (the Study Contractor) for the Federal Emergency Management Agency (FEMA). under Contract No. H-4012. This study was completed in October 1982. 1.3 Coordination The identification of streams requiring detailed study was accomplished at an April 14, 1976 meeting attended by personnel of FEMA, the City of Salina, Saline County, the Study Contractor, and the Kansas Board of Agriculture, Division of Water Resources (KS Bd Ag-DWR). Subsequent coordination for this study included contact with the U.S. Geological Survey (USGS); U.S. Army Corps of Engineers (COE), Kansas City District; the U.S. Department of Agriculture, Soil Conservation Service (SCS); the U.S. Department of the Interior, Bureau of Reclamation (USBR); the Kansas Water Office; the KS Bd Ag-DWR; Salina Airport Authority; and, Wilson & Company, Engineers & Architects (WCEA). At a January 17, 1978 meeting, the reduction of discharges along Mulberry Creek downstream of the Interstate 70 structures was reviewed by representatives of FEMA, the COE, the KS Bd Ag-DWR, and the Study Contractor. The decision was made to add detailed data for the Mulberry Creek overflow to carry the Mulberry Creek flow diverted by the Interstate 70 embankment. On February 9, 1978, preliminary flood elevations, flood boundaries, and floodway delineations for the detailed study streams outside of the Salina levee protection system were reviewed by the representatives of the city, the Study Contractor, the KS Bd Ag-DWR, FEMA, and the community at the intermediate meeting in Salina. On October 21, 1981, a technical meeting was held with representatives of Salina, Saline County, the Study Contractor, and FEMA to discuss a Special Problem report and a major change of scope of the Flood Insurance Study, due to new FEMA levee policy. This new policy required a minimum levee freeboard of three feet and required that the adequacy of the interior drainage system be evaluated on levees reportedly providing 100-year protection. The change of scope involved the interior drainage system and levee freeboard problems. At a December 2, 1981 meeting in Salina, new frequency curves for the USGS gage on Mulberry Creek at Salina were reviewed by representatives of the Study Contractor, FEMA, and the COE. The results of this gage analysis would be included as a part of the Salina-Saline County Special Problem Report. On June 10, 1982, a second technical meeting was held with representatives of Salina, the Study Contractor, FEMA, and WCEA to review the status and results of the additional work. A large part of south Salina was shown as floodprone. The adequacy of existing interior ponding areas still needed to be evaluated. On February 16, 1984, the results of this Flood Insurance Study were reviewed and accepted at a final coordination meeting attended by representatives of the Study Contractor, FEMA, the city, the county, and the KS Bd Ag-DWR. 2.0 AREA STUDIED 2.1 Scope of Study This Flood Insurance Study covers the incorporated area of the City of Salina, Saline County, Kansas. The area of study is shown on the Vicinity • Map (Figure 1). Flooding caused by overflow of the Smoky Hill River, the Saline River, Mulberry Creek, Mulberry Creek Overflow, and Dry Creek within the corporate limits was studied in detail. Magnolia Road Ditch and The Slough were added as detailed study streams with no floodway determination. The Old Smoky Hill River channel (inside the levee system) and the Old Dry Creek channel (inside the levee system) were reviewed for the availability of 100-year in-channel storage. Approximate analyses were used to study those areas having a low development potential or minimal flood hazards. 2 / 1 f ( = ` ` 0 1 I • �_ 1 ' I _ - _ -• -jct 1— — + _ �, I • ., i k E 1 . � = JS 1 I I1 1 ■ S I I 1 aD Wl1Da NOSfiN�191 e II; - J S L--- • 1- -- —4- --II 7�� , I F \,� I 0 ` y� , - - � Q J���'_� 111 `. • a z I a F ] 1. 1 1. . 1 i_ _i Q r T 1 1.* - 77' 1 o 1 i .7.- : 111 ( I. - oT . , . 8—_T,' _ ' --T 11 IS jliw.Ty w 3 ._ + — { -..+ • I 1 • t • J r .'113°.-.' 1 �•,-�.

FIGURE 1 Smoky Hill Tributaries No. 1 and No. 2 and Dry Creek Tributary No. 1 were studied by approximate methods. The areas studied were selected with priority given to all known flood hazard areas and areas of projected development or proposed construction through October 1987. The scope and methods of study were proposed to and agreed upon by FEMA and the City of Salina. 2.2 Community Description The City of Salina, the sixth largest city in Kansas and the county seat of Saline County, is centrally located in Saline County in central Kansas. The city is completely surrounded by the unincorporated areas of Saline County. Salina has a population of 41,843 according to the 1980 census, which was a • 10.4 percent increase from the 1970 census figure of 37,714 (Reference 1). Colonel William S. Phillips organized the Town Company of Salina and started the survey of the town site in March 1858. Salina was derived from the Federal government name for the Saline River, originally pronounced "Saleena." On March 30, 1859, the town company was granted a charter by the Sixth Territorial Legislature of Kansas. The plat of the survey was filed for record on April 14, 1862, and Salina became a town. The City of Salina hosts a large variety of industry, including the milling of flour, the processing of small grains, and the manufacturing of farm implements, concrete products, structural steel and metal materials, dairy products, beverages, meats, feeds, foods, airplanes, and many other marketable goods. Salina is served by a major airport; the Union Pacific Systems, the Atchison, Topeka & Santa Fe Railway; and the Oklahoma, Kansas, and Texas Railroad Company; colleges; and, other educational and historical institutions. It is also the distribution center for central Kansas. The City of Salina is located near the confluences of the Smoky Hill River, the Saline River, Mulberry Creek, and Dry Creek. The soils are typically deep, moderately deep, and shallow, dark grayish-brown and very dark grayish-brown silt loams, silty clay loams, and silty clays, with depths of more than 36 inches to the secondary carbonate deposits (Reference 2). The Salina area has a continental climate with yearly precipitation varying from a low of 15.24 inches (in 1956) to a high of 49.12 inches (in 1951). Average annual precipitation is approximately 29.25 inches. On the average, more than 70 percent of the annual precipitation occurs from April through September, but monthly and seasonal precipitation can be erratic. Precipitation during the summer is usually short duration thunderstorms with small centers of high intensity. The temperatures in the area range from a high of 118 degrees Fahrenheit (F.) (in 1936) to a low of -31 degrees F. (in 1905), with an annual average temperature of approximately 55.7 degrees F. (Reference 3). The Smoky Hill River, which flows through the eastern part of Salina, has a drainage area of approximately 8,360 square miles and has its headwaters in eastern Colorado. Approximately 501 square miles of the drainage area are uncontrolled below Kanopolis Dam and Reservoir. South of Salina, the Smoky Hill River flood plain averages about two miles in width. 4 The Saline River, which flows north of Salina, has a long narrow basin with its headwaters in Thomas County, Kansas. It has a drainage area of approximately 3,280 square miles. About 1,370 square miles of the drainage area are uncontrolled below Wilson Dam and Reservoir. Northwest of the city, the Saline River flood plain varies from 2.5 to 3.0 miles in width. Northeast of Salina, the Smoky Hill and Saline Rivers share a common flood plain divided only by the Union Pacific Railroad tracks. Mulberry Creek, which flows northwest of Salina, has a generally fan-shaped basin with its headwaters about 20 miles west of Salina in the eastern portions of Lincoln and Ellsworth Counties. It has a drainage area of approximately 290 square miles. The Mulberry Creek flood plain varies from 1.5 to 2.0 miles in width, west of Salina. The Dry Creek referred to in this study is that portion of the original Dry • Creek basin that is north of the Mentor-Dry Creek Diversion Levee, and drains to Mulberry Creek along the western edge of Salina. Dry Creek drains the runoff from the eastern part of the Salina Municipal Airport and from south Salina. This portion of Dry Creek has a drainage area of approximately 30 square miles. The remaining portion of Dry Creek that has been diverted south of Salina to the Smoky Hill River by the Mentor-Dry Creek diversion levee and channel will be referred to in this study as the Dry Creek Diversion and has a drainage area of approximately 131 square miles. The Dry Creek Diversion drainage area is a fan-shaped basin with its headwaters in extreme northern McPherson County, in the Lindsborg-Marquette Area. Magnolia Road Ditch was constructed by the City of Salina to divert approximately 2.8 square miles of south Salina drainage to the Dry Creek channel, instead of allowing it to flow north, through Salina, to the Old Smoky Hill River channel. The Magnolia Road Ditch drainage area begins about 4 miles south of Salina, near Mentor. The Slough runs from south to north through the middle of Salina approximately along Second Street, with an open channel from Cloud Street to Crawford Street. North of Crawford Street, the flow is carried by a 42- inch or 72-inch storm sewer, and by overland flow to the Old Smoky Hill River channel. South of Cloud Street, from Wayne Avenue and Fourth Street to Cloud and Quincy Streets, the runoff moves by overland flow. For small runoff events, The Slough has a drainage area of about 1.5 square miles, but for larger runoff events, the contributing drainage area increases as overflow from other drainage basins is added. The Old Smoky Hill River channel has been cut off from the present channel by the Smoky Hill River levee. The three main runoff storage segments of the Old Smoky Hill River channel are: (a) the portion beginning at Bill Burke Memorial Park (Lower Indian Rock Park), going through Kenwood and Oakdale Parks, past the east side of the business district, to Lakewood Park; (b) the portion at the "old" Holmquist sandpit area, just east of Albert Avenue and Mission Road; and, (c) the portion at the Knox sandpit area, east of Ohio Street and south of Magnolia Road. The Old Dry Creek channel has been cut off from the present channel by the Dry Creek and Mulberry Creek levees and, generally, follows a south to north line along the western edge of Salina from about Beverly Drive and 5 the Dry Creek levee to about Euclid Avenue and Thirteenth Street extended north. The Old Dry Creek channel has been broken into two segments by the filling of the channel between South and Walnut Streets. The major portion of Salina is situated on a broad alluvial flood plain with new residential development to the south of the present community within the levee system and on the rolling hills to the east of the Smoky Hill River. Some businesses have been developed on the flood plain along the Interstate Highways, both north and west of Salina. The former Schilling Air Force Base, which is now part of the city, has extensive development and is a prime area for continued development. 2.3 Principal Flood Problems Salina is located on the broad flood plain of four converging streams, any one of which could have caused flooding problems before the Salina levee protection project was completed in June 1961. The flood season in central Kansas normally begins with the spring rains and continues through early fall. Snowmelt does not contribute appreciably to the flood situation. Past floodflows have usually been caused by a continuous precipitation pattern which lasts for several days, associated with generalized storms over the basin. The condition most affecting the interior drainage problem is an extended period of above-normal rainfall ending with a high intensity storm. A study of available rainfall records indicates that an extended period of above- normal rainfall occurs about once every six or seven years. The occurrence of the high intensity rainfall as the climax to the wet antecedent condition has occurred only twice in the period of precipitation record from 1880 to date, in 1903, and 1951. The 1903 storm was the largest storm recorded and is considered to be a 100-year flood. The 1951 storm of July 9-12 has a frequency of about once in 50 years (Reference 4). Information obtained from newspaper accounts indicates a long history of flooding in the Salina area. Floods have occurred numerous times since 1844 when the first historical data were reported. On the Smoky Hill River, the greatest flood at Salina occurred in 1844, with the second greatest flood known occurring on May 29, 1903 (Reference 5). The five largest annual peaks recorded at the USGS gage on the Smoky Hill River near Mentor, Kansas are listed below. Discharge Estimated (cubic feet Storm Frequency Year per second (cfs)) (years) 1903 32,000 cfs (est.) 100 1927 25,500 cfs 66 1938 24,000 cfs 57 1973 20,300 cfs 42 1951 20,000 cfs 40 On the Saline River, the flood of July 13, 1951 was the greatest known since 1903 and exceeded the flood of May-June 1903 by about 1.0 foot from information supplied by Tescott residents (Reference 5). Tescott is located about 55 river miles upstream of Salina. The five largest annual peaks recorded at the USGS gage on the Saline River at Tescott, Kansas are as follows: 6 Year Discharge 1951 61,400 cfs 1957 13,600 cfs 1961 12, 900 cfs 1960 11 , 900 cfs 1973 9, 800 cfs The 1973 flood occurred after the completion of the Wilson Dam and Reservoir. No frequency analysis at the USGS gage at Tescott has been prepared since completion of Wilson Dam. Mulberry Creek can contribute significant flows to the Saline River north of Salina. These discharges would not be reflected in the gage record at Tescott. A USGS crest-stage partial-record station on Mulberry Creek near Salina has recorded stages since 1961. The four largest peaks recorded at the USGS gage (Reference 5) and the largest estimated peak are listed below. Estimated Storm Frequency Year Discharge (years) 1951 20,800 cfs (est.) 80 1971 7,500 cfs 8 1961 7,200 cfs 8 1974 7.200 cfs 8 1973 7,000 cfs 7 Early flood information regarding Mulberry and Dry Creeks in the Salina area is somewhat limited since most of the flood plains were in agricultural usage and flood events did not affect large numbers of people. The following accounts were taken from the Salina Journal and pertain to some of the earlier floods. Some Journal reports of the more recent floods affecting the northern part of the city are presented to indicate the present susceptibility of the area to flooding: May 26, 1903 - "The worst flood in the history of Salina is now raging and the entire portion of the city north of the Union Pacific and west of the Missouri Pacific tracks is entirely submerged. Portions of the city south of the Union Pacific tracks and west of Ninth Street, north of Ash are flooded and the waters are still rising." (Flooding from Mulberry Creek) May 27, 1903 - "The rise yesterday was from Mulberry; the rise today is from Dry Creek. The waters in Mulberry have receded and the creek is only about half filled, but Dry Creek has taken a great rise since morning and the water is raging over the country southwest of the city taking a course along the tracks into the northern part of the city and is spreading rapidly over the low lands." August 17, 1927 - "Water on Dry Creek at State Street now is 101 inches higher than at any other time this year. It has been at a standstill for 30 minutes at 3:15 o'clock." 7 June 6, 1938 - "When the Smoky Hill River broke over on South Ohio about 1:30 o'clock Sunday morning and started north toward Gypsum and Iron, east Salina knew there was trouble ahead. About the same time the dikes on Kansas and Penn began giving way." October 19, 1941 - "As a forerunner of what is expected to be the worst flood ever to strike Salina, Dry Creek lashed through its banks south of the city early this morning to spill angry waters into the already bankfull Smoky Hill. Unable to find an outlet, creek waters overflowed into east Salina and swirled the length of Fifth and adjacent streets in a mill race." October 20, 1941 - "Caught flatfooted by a flood which mushroomed overnight to record proportions Salina stood knee deep in muddy water this afternoon from the troublesome Dry Creek Watershed and waited apprehensively for what may yet come from up the Smoky Hill Valley. In four hours Salina's beleagured east side was flooded and water ran sidewalk deep through many parts of the business district. "By noon, from atop the United Life Building, half of Salina and all the surrounding countryside could be seen to resemble the land of 10,000 lakes. To the west flash floodwaters rolled down Dry Creek and into low fields spreading out as wide as two miles." July 11, 1951 - "County Engineers, Hal Everett's staff said they found a sheet of water starting two miles west of Salina and extending as far as they could see in the State Street road vicinity. They said it was water from the junction of Spring and Mulberry Creek which join five miles west of the city." July 12, 1951 - "The overflowing Smoky, still climbing, sent water over the entire east side." "The north end went under as Dry Creek charged out of its banks and Mulberry Creek and Saline River backed up and flowed into town from the north." "Dry Creek waters flooded west and northwest Salina too. Water from south of Salina drained into the draw in the southeast section of the city, overflowing it and flooding that area." Friday, July 13, 1951 - "More than three-fourths of the city was under water Friday, but no casualties had been reported. In some areas overflows were reported dropping." "It was estimated between 1,500 and 2,000 persons had fled their homes. The Smoky Hill River dropped two-tenths of an inch during the morning and at noon stood at 24.2. But no one knew why." "But Salina isn't out of the woods and water yet. The furious Saline River, highest in history of north Salina, could back water into the already swollen Mulberry Creek and Dry Creek sending water into the north end." 8 May 23, 1971 - "The mighty little Mulberry Creek flexing its watery muscles after long years of placid living drove members of some 20 families from their homes west of Salina Saturday, then Saturday night began mauling parts of north Salina." "Flooding severely in the wake of rains which measured up to 6.01 inches the Mulberry was threatening to close U.S. Highway 81 at the north edge of Salina late Saturday night and had forced 4 or 5 more families to move out of their homes near North 5th Street Road and Stimmel Road east of U.S. 81." "Three service stations to the west side of U.S. 81 and south of Interstate 70 were awash with several feet of water and the creek was lapping at the edge of the parking lot of the Mid-America Inn on the east side of 81." "A dike on the south side of Mulberry protects most of Salina but persons living on the north side of the dike were at its mercy." "Water from the Mulberry flowed down North 5th Street Road." "There was one cheerful note, however, old time flood watchers said the Mulberry was not as high as it was in the Big Flood of 1951." "However things have changed along the streams. The dike and Interstate 70 north of the creek probably have changed its patterns as have the numerous commercial developments along its banks near the intersection of Interstate 70 and U.S. 81." "U.S. 40 Highway was closed to cars Monday afternoon one mile west of Salina. Overflowing Mulberry Creek covered an approach to a bridge west of the U.S. 40-State Street Road intersection." September 30, 1973 - "At Salina, Mulberry Creek yo-yoed down once more. There were no rains reported on the Mulberry and the creek appeared to be moving swiftly and falling Saturday afternoon. Thomas Park has reappeared and service stations in the Interstate 70 - U.S. 81 area which had been flooded were open. White Trucks and Stewart International Harvester in the Truck Haven area continued surrounded by water." October 11, 1973 - "Mulberry Creek was on its usual rampage and at noon was reported rising rapidly at Salina's north edge." May 20, 1974 - "Mulberry Creek rose rapidly Sunday closing 5th Street Road and flooding areas near the U.S. 81 and I-70 interchange. Thomas Park was under water and North Ohio Street was cut south of the I-70 interchange." A photograph of the May 1971 flood is shown in Figure 2. In addition to the riverine flooding of the Smoky Hill River, the Saline River, Mulberry Creek, Dry Creek, and Dry Creek Diversion, most of Salina can be flooded from intense local thunderstorms compounded by inadequate local drainage, as occurred in October 1973, April 1974, August-September 1977, and June 1981. 9 i- i 3 .. a FP -3r :14 -V-j i_._. L Ag• zt • FIGURE 2 - International Harvester Company looking east from North 9th Street, just south of the Interstate 70 interchange, May 1971. (COE FPI photo) 10 "A portion of the existing drainage problem results from inadequate outlet discharge to and through the flood protection levee to the east of Salina and the inadequate drainage capacity of Dry Creek located to the west of Salina. Another portion of the problem consists of inadequate drains to the outlets." "Existing drainage systems within the city limits do not provide protection for a reasonable runoff rate; therefore, frequent flooding of streets and isolated vacant land areas occur. More, intense storms result in occasional physical property damage. As the urbanization of the area increases, the existing drainage systems will become less effective and difficult to maintain" (Reference 6). The following accounts were taken from the Salina Journal and pertain to some of the more recent floods. On August 31 - September 1, 1977, a local high intensity thunderstorm unofficially dumped as much as 8 inches of rainfall on southern Salina, and flooded an extensive portion of south Salina: "It was August 31, 1977, when a freak storm began which left acres of south Salina flooded for several days. It took several days for the surface water to recede and gurgle its way to a sand pit east of the area." Photographs of the August-September 1977 flood are shown in Figures 3-5. "A heavy thunderstorm early Thursday (June 11, 1981) that dumped nearly six inches in a three-hour period left Salina looking like Venice for a few hours." "Within a half-hour some streets were flooded. There also were many reports of water in basements." "Throughout the city, Salinans found themselves floundering in a sea of water following one of the biggest storms to hit the city since the fall of 1977." Photographs of the June 1981 flood are shown in Figures 6-8. 2.4 Flood Protection Measures A system of three flood control dams has been constructed in the Smoky Hill and Saline River basins above Salina. Two of these reservoirs are on the Smoky Hill River. Cedar Bluff Dam and Reservoir has a drainage area of • 5,530 square miles and began storage November 13, 1950. Kanopolis Dam and Reservoir. downstream of Cedar Bluff, has a drainage area of 7,857 square miles and began storage February 17, 1948. The uncontrolled emergency spillway crest of Kanopolis Dam is elevation 1,507 feet National Geodetic Vertical Datum of 1929 (NGVD). The maximum pool elevation was 1,506.98 feet NGVD on July 14, 1951. One reservoir is on the Saline River. Wilson Dam and Reservoir has a drainage area of 1,917 square miles and began storage December 29, 1964. These structures were on-line prior to the 1973 flood events on the Smoky Hill and Saline Rivers. "It should be noted, however, that the storms causing the 1903 and 1951 floods occurred substantially downstream from the reservoirs and a recurrence of these 11 ,� �, , f A pR' « 1 r RI 7(' Ise .

The Salina Flood Protection Project. completed in June 1961, provides protection from external flooding sources for a large part of Salina. The flood control project includes the improvements of two miles of Mulberry Creek between North 9th Street and the Union Pacific Railroad bridge. The major portion of the Dry Creek drainage area has been diverted eastward into the Smoky Hill River through the Dry Creek Diversion consisting of approximately two miles of diversion channel at a point just south of the city. The remaining downstream part of the Dry Creek channel has a length of approximately five miles. The reach between Interstate 135 and the Union Pacific Railroad bridge over Mulberry Creek has been straightened and leveed. The Smoky Hill River was improved by 4.4 miles of channel cutoffs and 4.3 miles of channel improvements. The Salina levee system protects the city from flooding on the Smoky Hill River, the Saline River. Mulberry Creek, and Dry Creek by approximately 14 miles of levees. The City of Salina sponsors, owns, and maintains this levee system (Reference 8). All land occupied by the local levee system is included in the corporate limits of the City of Salina. However, owing to cartographic limitations, the maps do not depict this condition. Portions of the Mulberry and Dry Creek levees do not have the freeboard required by FEMA levee policy for protection from the 100-year flood. However, the COE, in a letter dated October 18, 1982, stated that the Mulberry and Dry Creek levees "would still provide the initially designed 100-year frequency protection." No local flood protection has been provided for development along North 9th and North 5th Streets between the levee and the Saline River. and along the west or left bank of Dry Creek, particularly in the vicinity of the former Schilling Air Force Base, except for part of the Schilling Manor housing area. Two organized SCS watershed districts are located upstream of the Salina area--Lost Creek Watershed and Spillman Creek Watershed (Reference 9). In addition to the above structural measures of flood protection, there are non-structural measures being utilized to aid in the prevention of future flood damages. These measures are in the form of land use regulations that use the best available information to control further building within areas • that have a high risk of flooding (Reference 10). 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 flood plain 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 15 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 the peak discharge- frequency relationships for each flooding source studied in detail affecting the community. The COE Flood Plain Information (FPI) report for Salina, Kansas (Reference 11) served as the basis for the Smoky Hill River, Saline River, and Dry Creek Diversion discharge-frequency relationships. Where flows were not given in the report or in other data furnished by the COE, the 10-and 500- year discharges were determined from straight line extrapolation on a log- probability plot of the 25-, 50-, 75-, and 100-year discharge information. The peak discharges for the Smoky Hill River at New Cambria (see Table 1) represent the flow in the Smoky Hill River Channel and immediate flood plain south of the Union Pacific Railroad tracks. The flow in the total Smoky Hill valley at the confluence of the Saline River would be greater. The discharges for Mulberry Creek were revised from the values in the COE FPI report (Reference 12) by using the records of the USGS gage on Mulberry Creek (with a drainage area of 250 square miles) near Salina, Kansas (Reference 5), which has been in operation since Water Year 1961. The values of the 10-, 50-, 100-, and 500-year peak discharges were obtained from a floodflow frequency analysis computer program based on the log-Pearson Type III distribution of annual peak discharges (Reference 13). Modifications to the analysis include: 1) an estimated historic flood (1951) was added to the data, and 2) a regional skew coefficient of -0.2 was used. The discharges for Dry Creek were revised from the values in the COE FPI report (Reference 12) by using an SCS TR-20 model of the watershed. The discharges for Magnolia Road Ditch and The Slough were also determined using the SCS TR-20 model (Reference 14), which considers drainage area, • soil type, land use, time of concentration, precipitation, in-channel storage, and timing of the hydrograph peaks (References 15, 16, and 17). Valley storage for flood routing was determined from HEC-2 runs along the streams (Reference 18). The Dry Creek-Magnolia Road Ditch-The Slough system is a complex watershed. The Dry Creek hydrographs were peaking at Magnolia Road at approximately the same time as the Magnolia Road Ditch hydrographs were beginning to peak at Dry Creek. The Dry Creek discharges and water-surfaces would submerge the uncontrolled concrete 16 box culvert under Interstate 135 and actually force Magnolia Road Ditch to flow backwaters into the levee-protected area of south Salina. Because the lower portion of '\lagnolia Road Ditch flows backwards at the same time the Magnolia Road Ditch hydrographs peak, the Magnolia Road Ditch flows break over the manmade watershed boundary, and flow north toward The Slough and east to the Old Smoky Hill River channel. It appears from the TR-20 hydrograph modeling that the waters from Dry Creek flowing backward in Magnolia Road Ditch and the waters from Magnolia Road Ditch breaking over the watershed divide would not add significantly to The Slough peaks, but would extend the duration of flooding and would increase the volume of water to be handled by the Old Smoky Hill River channel. Before the construction of Magnolia Road Ditch, the runoff from this drainage area originally flowed north through a natural swale to The Slough channel. • After the construction of this diversion ditch, a large portion of the natural swale was filled and developed into a residential area, south of Cloud Street. In Table 1, the peak discharges for the Saline River and Mulberry Creek downstream of Interstate 70 were reduced to reflect the inadequacy of Interstate 70 structures to carry flows downstream. Peak discharges for Magnolia Road Ditch downstream of the Union Pacific Railroad and Belmont Boulevard were reduced to reflect diversion of flows north and east into the city. The volume of required storage for the Old Smoky Hill River channel and the Old Dry Creek channel were calculated assuming the streams outside the levee system were up (no gravity flow outlets open), no pumping, and a volume of runoff equal to the drainage area times the inches of direct runoff. Peak discharges for the 10-, 50-, 100-, and 500-year floods of each flooding source studied in detail plus the in-channel storage volumes for the ponding areas in the community are shown in Tables 1 and 2, respectively (Reference 4). 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 the floods of the selected recurrence intervals. Cross-section data for the Smoky Hill River, the Saline River, Dry Creek Diversion, and Mulberry Creek in the study area were obtained from the COE, Kansas City District, computer runs used in preparing the FPI reports for Salina (References 11 and 12). The FPI cross sections were originally taken from USGS 7.5 minute, 10-foot contour interval quadrangle sheets of the Salina area (Reference 19). Most bridge information was also obtained from the FPI computer runs and from COE bridge plots. On the Smoky Hill River bridge at Magnolia Road, the USGS stream gage was modified with information taken from the Smoky Hill River navigability study (Reference 6). The Saline River bridge profiles for Interstate 70 and North 9th Street were modified to better reflect present road grade profiles. The Mulberry Creek bridges for 5th Street, 9th Street, and the Union Pacific Railroad tracks were modified with field survey data. These modifications were necessary to better reflect present conditions. 17 el u 03 •v as X o Wr� O O O N O O O O O O O O O CA r >•1 O O O O O O O L I O co, E O r- .i .4 ,-1 '.4 0 U 03 o cV co 0 0 O CO 00 c>. i:+ a) M co M L a.) a a r... 3 w a m ° •vo E U ,-1 o 0 o cv © O to a� "W o © © 0 o a © E q 3 L 1 co. o 0 0 o 0 0 a) O •4-' v) 1 cn W O N N cV O O 'v C O M M M r0-1 e� W w O d CID , V .

Bridges and culverts were field surveyed to obtain elevation data and structural geometry. The remaining cross-section data for Dry Creek were obtained from "South Salina Drainage Study for the City of Salina, Kansas" (Reference 6). Cross-section data for most of Magnolia Road Ditch were taken from 2-foot contour interval mapping of south Salina (Reference 20). The remaining cross sections, where the channel has been improved near Salina-South High School, were field surveyed. Bridges and culverts were taken from "South • Salina Drainage Study for the City of Salina, Kansas" (Reference 21). Cross-section data for The Slough were taken from 2-foot contour interval mapping of that area (Reference 22) and the "South Salina Drainage Study for the City of Salina, Kansas (Reference 21). Bridge and culvert data were also taken from the South Salina drainage study. Cross-section data used to evaluate the in-channel storage volumes of the Old Smoky Hill River channel and the Old Dry Creek channel were obtained by field survey methods or digitized from aerial photos of the channels (Reference 23). Bridges and culverts were field surveyed to obtain elevation data and structural geometry. Cross-section data for stream segments studied by approximate methods were developed from 10-foot USGS contour mapping (Reference 24). Locations of selected cross sections used in the hydraulic analyses are shown on the Flood Profiles. For stream segments for which a floodway was computed (Section 4.2), selected cross-section locations are also shown on the Flood Boundary and Floodway Map. Roughness coefficients (Manning's "n") for all streams were estimated by field inspection, aerial photographs of the Salina area (References 23 and 25), and FPI computer runs. The range of roughness coefficients for the main channel and the remainder of the flood plain for each stream studied in detail is as follows: Channel Overbank Flooding Source "n" Value "n" Value Smoky Hill River 0.022 (COE) 0.050 (COE) Saline River 0.022 (COE) 0.050 (COE) Dry Creek Diversion 0.022 (COE) 0.050 (COE) Mulberry Creek 0.080 - 0.090 0.060 Mulberry Creek Overflow 0.060 0.060 Dry Creek 0.035 - 0.050 0.055 - 0.070 Magnolia Road Ditch 0.025 - 0.070 0.040 - 0.070 The Slough 0.025 - 0.040 0.025 - 0.080 Old Smoky Hill River Channel 0.045 0.060 Old Dry Creek Channel 0.045 0.075 22 Water-surface profiles for all detailed study streams were developed using a HEC-2 step-backwater computer program (Reference 18). The starting water-surface elevations for the Smoky Hill River were estimated by extrapolation of the USGS gage rating curve at New Cambria, Kansas. The extrapolated rating curve of the USGS gage near Mentor, Kansas was used to check the profile runs. Reasonable agreement was achieved at this second site. The starting water-surface elevations for the Saline River at its confluence were determined from the backwater calculations on the Smoky Hill River. The starting water-surface elevations for Mulberry Creek, Mulberry Creek Overflow, Dry Creek, Dry Creek Diversion, Magnolia Road Ditch, and The Slough were determined using the slope-area method. The extrapolated rating curve of the USGS gage on Mulberry Creek was used to check the Mulberry Creek profile runs, and reasonable agreement was achieved. Mulberry Creek Overflow from Mulberry Creek to the Saline River south of Interstate 70 was established to carry the excess discharge that the Interstate 70 structures would not handle at each frequency and water- surface elevation. This natural overflow will reduce the water-surface elevations immediately upstream of the Interstate 70 structures. The FPI report for Mulberry Creek assumed all flow would pass through the Interstate 70 structures over Mulberry Creek. Slope-area calculations were made at several cross sections along South Ohio Street and Magnolia Road to account for the flow of Magnolia Road Ditch, which breaks over the drainage area divide and flows north and east into residential areas of Salina, and to determine the 100-year sheet flow elevations. The in-channel storage and pumping facilities for the Old Smoky Hill River channel and the Old Dry Creek channel were designed for a 25-year design storm. The present in-channel storage volume of the Old Smoky Hill River channel between elevations 1.203 and 1,216 feet NGVD appears to match the usable temporary 25-year design storage volume between elevations 1,203 and 1,216 feet NGVD, but to handle the 100-year storage requirement, additional storage volume is necessary. The present in-channel storage volume of the Old Dry Creek channel between elevations 1,207 and 1.217 feet NGVD appears to be only one-third of the temporary 25-year design storage volume between the same elevations. Thus, additional storage volume is necessary, and ponding will occur in low areas that are drained by • storm sewers to the Old Dry Creek channel. The available data indicate that the 500-year water-surface profiles would overtop the Salina levee system along Dry Creek. However, in accordance with the requirements of FEMA levee policy, the COE has certified that Mulberry and Dry Creek levees "would still provide the initially designed 100-year frequency protection." Flood profiles were drawn showing the computed water-surface elevations for floods of the selected recurrence intervals. The hydraulic analyses for this study are based only on the effects of 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. 23 All elevations are referenced to the NGVD. Elevation reference marks used in this study are shown on the maps. 4.0 FLOOD PLAIN MANAGEMENT APPLICATIONS The National Flood Insurance Program encourages state and local governments to adopt sound flood plain management programs. Therefore, each Flood Insurance Study produces maps designed to assist communities in developing flood plain management measures. • 4.1 Flood 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 flood plain 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 in detail outside of the Salina levee system, the boundaries of the 100- and 500-year floods have been delineated using the elevations determined at each cross section. Between cross sections, the boundaries were interpolated using USGS topographic maps at a scale of 1:24000 with contour intervals of 10 feet (Reference 24). For the streams studied in detail inside the Salina levee system, the boundaries of the 100-year flood have been delineated using the elevations determined at each cross section; between cross sections, the boundaries were interpolated using topographic maps at a scale of 1:1200 with a 2-foot contour interval (References 20 and 22) and USGS topographic maps at a scale of 1:24000 with a contour interval of 10 feet (Reference 24). A 100-year sheet flow delineation has been determined along the eastern edge of the Bonnie Ridge subdivision, Scott and Neal Avenues at south Ohio Street; along Magnolia Road and Belmont Boulevard to Ohio Street; along South Ohio Street from Magnolia Road to Shalimar Drive; and, along Belmont Boulevard from about Kensington Road to Wayne Avenue. This sheet flow delineation is comparable to the August-September 1977 flooding. The 100-year ponding areas, which have been designated or proposed, have been delineated using the calculated 100-year water-surface elevations and the available mapping of the area. If the mapping indicates other low areas would flood due to the 100-year ponding elevations, these areas are also shown. Along the Old Dry Creek channel, the available mapping was inadequate to show the low areas that would flood if the 100- • year storage elevations would be reached. The excess runoff from the 100- year storm would pond in the industrial, commercial, and residential • districts located east of the Old Dry Creek channel. The remainder of the area inside the Salina levee system has been shown as 500-year flood plain because 1) the Dry Creek and Dry Creek Diversion levees are overtopped by the 500-year flow, 2) the area is protected from the 100-year riverine flooding by the Salina levee system but still subject to flooding from failure or overtopping during a larger flood (residual risk of flooding), and 3) the area is subject to 100-year shallow flooding where average depths are less than 1.0 foot or where the contributing drainage area is less than 1.0 square mile. Flood boundaries for the approximate study areas were delineated on these maps using slope-area calculations, past historical data, the City of Salina Flood Hazard Boundary Map, and the Saline County Flood Hazard Boundary Map (References 26 and 27). 24 The blocking of bridge or culvert openings, or the plugging of storm sewers during a period of storm runoff could result in the flooding of areas outside those shown by these flood delineation lines. The 100- and 500-year flood plain boundaries are shown on the Flood Boundary and Floodway Map. In cases where the 100- and 500-year flood plain boundaries are close together, only the 100-year boundary has been shown. Small areas within the flood plain 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 Flood ways Encroachment on flood plains, 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 flood plain management involves balancing the economic gain from flood plain development against the resulting increase in flood hazard. For purposes of the National Flood Insurance Program, a floodway is used as a tool to assist local communities in this aspect of flood plain management. Under this concept. the area of the 100-year flood plain is divided into a floodway and a floodway fringe. The floodway is the channel of a stream plus any adjacent flood plain 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 1.0 foot, provided that hazardous velocities are not produced. The floodways for the Saline River, part of the Smoky Hill River, part of Mulberry Creek, and part of Dry Creek were computed on the basis of equal conveyance reductions from each side of the flood plain and then adjusted, as necessary, to try to maintain a 1.0-foot increase in elevation over the 100-year water-surface elevation. Since a majority of the Smoky Hill River east of Salina flows between the levee on the left bank and higher ground on the right bank, the floodway shown is the effective area necessary to carry the 100-year flood with no increase in flood elevations as determined from COE cross-section data. The Mulberry Creek Overflow floodway was computed to carry that portion of the 100-year floodflow that would not pass through the Interstate 70 structures over Mulberry Creek to the Saline River. No increase in the floodway elevation over the 100-year water-surface elevation was allowed along Mulberry Creek between North 5th Street and North 9th Street, and along Dry Creek in the vicinity of West State Street Road and downstream. . due to the lack of the required 3- to 4-feet of levee freeboard. Just upstream of West State Street Road and West Crawford Street, the total 100-year flood plain along Dry Creek was designated as floodway to preserve the overbank valley storage used in the TR-20 model to reduce the size of the discharges as the flow moved downstream. In the vicinity of Magnolia Road along Dry Creek, a minimal increase in floodway elevation over the 100-year water-surface elevation was allowed, due to the fact that any increase in elevation would increase the backward flow of Magnolia Road Ditch through the uncontrolled concrete box culvert under Interstate 135 and into the levee-protected area of Salina. No floodways were computed for the flooding sources inside the Salina levee protection area because flooding was caused by inadequate local drainage and was classified as shallow ponding and sheet runoff. 25 The results of these computations were tabulated at selected cross sections for each stream segment for which a floodway was computed and are presented in Table 3, Floodway Data. As shown on the Flood Boundary and Floodway Map, the floodway boundaries were computed at cross sections. Between cross sections, the boundaries were interpolated. In cases where the boundaries of the floodway and the 100-year flood are either close together or collinear, only the floodway boundary has been shown. The area between the floodway and the 100-year flood plain boundaries is termed the floodway fringe. The floodway fringe thus encompasses the portion of the flood plain 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 flood plain development are shown in Figure 9. E- 100-YEAR FLOOD PLAIN '1 FLOODWAY FLOODWAY .FLOODWAY.

This difference may not have a variation greater than that indicated in the following table for more than 20 percent of the reach: Average Difference Between 10- and 100-year Floods Variation Less than 2 feet 0.5 foot 2 to 7 feet 1.0 foot 7.1 to 12 feet 2.0 feet More than 12 feet 3.0 feet The locations of the reaches determined for the flooding sources of the City of Salina are shown on the Flood Profiles and are summarized in Table 4, Flood Insurance Zone Data. 5.2 Flood Hazard Factors The Flood Hazard Factor (FHF) is used to establish relationships between depth and frequency of flooding in any reach. This relationship is then used with depth-damage relationships for various classes of structures to establish actuarial insurance rate tables. The FHF for a riverine reach is the weighted average difference between the 10- and 100-year flood water-surface elevations rounded to the nearest 0.5 foot, multiplied by 10, and shown as a 3-digit code. For example, if the difference between elevations is 0.7 foot, the FHF is 005; if the difference is 1.4 feet, the FHF is 015; if the difference is 5.0 feet, the FHF is 050. When the difference is greater than 10.0 feet, it is rounded to the nearest whole foot. 5.3 Flood Insurance Zones Flood insurance zones and zone numbers are assigned based on the type of flood hazard and the FHF, respectively. A unique zone number is associated with each possible FHF and varies from 1 for a FHF of 005 to a maximum of 30 for a FHF of 200 or greater. Zone A: Special Flood Hazard Areas inundated by the 100-year flood, determined by approx- imate methods; no base flood elevations are shown or FHFs determined. Zone AH: Special Flood Hazard Areas inundated by types of 100-year shallow flooding where depths are between 1.0 and 3.0 feet; base flood elevations are shown, hut no FHFs are determined. 29 Zones Al, A4, A5, A7, A8, Special Flood Hazard Areas inundated by Al2, A20: the 100-year flood, with base flood elevations shown, and zones subdivided according to FHF. Zone B: Areas between the Special Flood Hazard Areas and the limits of the 500-year flood; areas that are protected from the 100- and 500-year floods by dike, levee, or other water control structure; areas subject to certain types of 100-year shallow flooding where depths are less than 1.0 foot; and, areas subject to 100- year flooding from sources with drainage areas less than 1 square mile. Zone B is not subdivided. Zone C: Areas of minimal flooding; not subdivided. Flood elevation differences, FHFs, flood insurance zones, and base flood elevations for the flooding source studied in detail in the community are shown in Table 4, Flood Insurance Zone Data. 5.4 Flood Insurance Rate Map Description The Flood Insurance Rate Map for the City of Salina is, for insurance purposes, the principal product of the Flood Insurance Study. This map contains the official delineation of flood insurance zones and base flood elevation lines. Base flood elevation lines for riverine flooding sources show the locations of the expected whole-foot water-surface elevations of the base (100-year) flood. The base flood elevations and zone numbers are used by insurance agents, in conjunction with structure elevations and characteristics, to assign actuarial insurance rates to structures and contents insured under the National Flood Insurance Program. 6.0 OTHER STUDIES The National Weather Service (formerly the U.S. Department of Commerce, Weather Bureau) reviewed the 1951 flood, with flood profile information on the Smoky Hill and Saline Rivers in the vicinity of the City of Salina (Reference 28). The COE, while designing the Salina levee protection project, prepared the design memorandum that was the source of the original interior drainage design information and drainage area boundaries (Reference 4). The COE "Flood Plain Information, Smoky Hill River, Kansas, Salina to the Mouth near Junction City" study published low water, "flood stage," modified 25-year flood, actual July 1951 flood, and modified standard project flood stream profiles on the Smoky Hill River in the vicinity of Salina (Reference 7). The COE "Flood Plain Information, Smoky Hill River, Saline River, Dry Creek Diversion, Salina, Kansas" (Reference 11) "Flood Plain Information, Mulberry Creek, Dry Creek, Salina, Kansas" (Reference 12) studies served as the main sources of basic data for this Flood Insurance Study.

The Mulberry Creek and Dry Creek discharges were revised and the Mulberry Creek Overflow was added to the analysis. Due to the critical effects of Dry Creek on Salina drainage, Dry Creek was field surveyed. Thus, the flood elevations and boundaries will be different from those shown in the FPI studies. WCEA has prepared 2-foot contour mapping of part of south Salina and has prepared the "South Salina Drainage Study" for the City of Salina for the purposes of reviewing and making recommendations concerning the inadequate internal drainage of south Salina. Due to its more detailed analysis, this Flood Insurance Study supersedes the previously printed Flood Hazard Boundary Map for the City of Salina (Reference 26). A Flood Insurance Study for Saline County, Unincorporated Areas, Kansas is in progress (Reference 29). This report will match the county study exactly. 7.0 LOCATION OF DATA Information concerning the pertinent data used in the preparation of this study can be obtained by contacting the Natural and Technological Hazards Division, Federal Emergency Management Agency, Federal Office Building, Room 305, 911 Walnut Street, Kansas City, Missouri 64106. 8.0 REFERENCES AND BIBLIOGRAPHY 1.

ARMY KANSAS CITY DISIHICT AREA MAP MULBERRY CREEK AND DRY CREEK SALINA, KANSAS- ,Elz A-16-211 LATE NO.I PREFACE This report evaluates the hazards resulting from floods occurring on Mulberry Creek and Dry Creek in the vicinity of Salina, Kansas. With development progressing north of the city and also to the west in the vicinity of the interstate highways, even minor to mod- erate flooding can become a serious problem to flood plain development. Studies show a large flood occurring today in the developed portions of the flood plain could have serious consequences not only to those affected but, also to the economy and general welfare of the entire community. This report was prepared at the joint request of the City of Salina and the County of Saline through the Kansas Water Resources Board under continuing authority provided the Corps of Engineers in Section 206 of the 1960 Flood Control Act 'Public Law 86.645) as amended. Plate 1, on the opposite page, shows the flood plain areas which are discus- sed in this report. Contents of the report include a discussion of the flood hazard, maps, profiles and cross sections indicating the approximate extent of flooding which could be expected in the future under existing conditions. A glossary is also included to assist in the understanding of unfamiliar terms used in this report. Historical information, streamflow records, pre- cipitation data and other technical data have been used in defining the size and occurrence of potential flooding in Salina due to Mulberry Creek and Dry Creek floodwaters. The flood situation as presented in this report is intended to be used as an aid in the identification of local flood problems and to promote the best utilization of lands subject to overflow. By use of this information, flood risks may be appraised, and both general and special development programs may be planned to avoid or reduce flood damage. It should be recognized that the flood hazards as presented are evaluated as of the date of this re- port. Special plans and recommendations for the solution of flood problems are not in- cluded as these are properly the responsibility of local government. However, a basis is provided for study and planning on the part of the city of Salina to minimize vulnerability to flood damages. Use of flood plain regulations, zoning or subdivision regulations, flood proofing and construction of flood protection works, or a combination of these approaches may be implemented by planners in the guidance of those who would propose utilization of the flood plain. . Copies of this report and information on its use are available from the Office of the Mayor of Salina, Kansas, and the Kansas Water Resources Board. Technical assistance to Federal, State and local agencies in the interpretation of the information contained herein will be provided, upon request, by the Corps of Engineers, Kansas City District. BACKGROUND INFORMATION Settlement • Salina, the sixth largest city in Kansas and the county seat of Saline County, lies in the center of the fertile valley of the Smoky Hill River. Nomadic Indian tribes , including the Cheyenne , Arapahoe, Kiowa and Pawnee were well acquainted with this area for they came from all directions to take advantage of the supply of plentiful water, wild game, and abundant vegetation so characteris- tic of the Smoky Hill region . Colonel William Phillips organized the Town Company of Salina and started the survey of the townsite in March 1858. One year later three general stores were enjoying a profitable busi- ness although most of the trade was with the Indians . On April 14, 1862 , Salina officially took its place on the map as a newborn town in Kansas. Manufacturing was introduced into the county in 1861 with the erection of the first saw mill and a grist mill . Little anyone realized at the time that this grist mill would be the begin- ning of the city's most lucrative and thriving industry. The advent of the Kansas Pacific Railroad in 1867 stimu- lated business and growth of the city , but this growth was not with- out hardship and tragedy. Numerous terrifying Indian raids , two destructive fires which destroyed many homes and businesses , flood , drought, famine and the grasshopper plague, all in turn , dealt severe and crippling blows to the city of Salina. However, after each of these calamitous events, the citizens were prompt in rebuilding and restoring their town. Today the city of Salina, with 37,700 residents , hosts a large variety of industry. It contains an international airport, four major railroads , two fully-accredited colleges , other educa- tional and historical institutions , and is the wholesale distribution center for Central and Northwest Kansas. The foremost industry in the city is the milling of flour and processing small grains . Other commodities manufactured are: farm implements , concrete products , structural steel and metal materials , dairy products , beverages , meats , feeds , and many other marketable goods . The Streams and Their Valleys As shown on Plate 2, opposite, the Mulberry Creek Basin lies partially within the north city limits and extends about twenty miles to the west. The basin is generally fan shaped with surface elevations varying from 1210 feet mean sea level (m.s .l . ) at the mouth to 1750 ft. , m.s . l . at the west edge of the basin . Mulberry Creek drains an area of 271 square miles and is characterized by a serpentine stream with a wide flood plain in gentle rolling uplands . Flood plain widths of Mulberry Creek average one and a half miles at the upper end of the study reach and spread to two miles near the mouth. Mulberry Creek , near its mouth , shares a common flood plain with Dry Creek and the Saline River giving a much wider flood plain than would normally occur for a stream this size and in this terrain. The stream slope averages three feet per mile and the width varies from 50 to 150 feet throughout the study reach. Portions of the lower basin are becoming urbanized but most of the land is in agricultural use. That portion of the Dry Creek Basin covered in this re- port lies south of the Mulberry Creek Basin along the western city limits and includes twenty seven square miles which was not diverted to Smoky Hill River by the Salina Flood Protection Project. This remaining portion of Dry Creek has been altered considerably from its natural state by the above project and channel realignment. Most of the basin is agricultural with approximately five square miles being used by the airport and surrounding buildings . The creek channel varies from 40 to 100 feet and the slope is approxi- mately four feet per mile. 2 N I j N O }.

S. Highway 81 and I-70 interchange. Most of the businesses are related to highway trade such as gas service stations , truck stops , rest- aurants and motels . The International Harvester Co. Sales and Service building located between Fifth and Ninth Streets on the Mul- berry Creek left bank , has been flooded in the past. A large truck stop facility is located immediately west of the Inter- national Harvester Co. and adjacent to I-70. Also at Ninth Street on the right bank are two motels , restaurants , service stations and a mobile home sales company. Upstream of Ninth Street urban development is sparse the area being mostly agri- cultural in nature. No concentrated development has taken place in the Mulberry Creek flood plain west of Salina but with future construction of Interstate Highway 35 it can reason- ably be expected. There is also scattered development in the Dry Creek flood plain. The right bank flood plain is within the Salina Flood Protection Project from the mouth to Magnolia Road , while the left bank flood plain has no flood protection. In the area where Dry Creek skirts the west city limits , the right bank flood plain contains development consisting of residential and commercial . The left bank flood plain is sparsely developed with it generally being farms , a trucking company and the airport. The city now has annexed Schilling Air Force Base and some non-military business and commercial activity have already moved into the facility. It is a prime development site due to proximity to major highways and availability of ready-built buildings . 3 FLOOD SITUATION Data Sources and Records There is only one stream gaging station located within the Mulberry Creek Basin. This station, monitoring flows from approximately 271 square miles of Mulberry Creek , was established by the United States Geological Survey in March 1961 . The gage is located on the downstream side of the county road bridge be- tween Sections 8 and 9 1. 14S , R 3W. The gage equipment consists of a crest stage indicator and Type A wire weight gage. Zero stage for this facility is 1208.42 feet above mean sea level . Extreme flows range from zero flow on several occasions up to a maximum flow of 7800 cubic feet per second on May 22, 1971 , (26.94 feet gage height) .

The average annual precipitation is 28.4 inches with variation from 12.98 inches in 1966 to 50.94 inches in 1959. Intense hourly rainfalls such as the 1 .86 inches recorded on September 3, 1967 and 1 .56 inches on July 11 , 1963 are of frequent occurrence in the Salina area. 4 Flood Season and Flood Characteristics The flood season in central Kansas normally begins with the spring rains and continues through early summer. Snowmelt does not contribute appreciably to flood situations . Past flood flows in Mulberry Creek have usually been caused by continuous precipitation lasting for a day or more associated with generalized storms over the basin. Flows from these storms are characterized by high stages , high velocities and medium length durations . Factors Affecting Flooding Flood Damage Prevention Measures - A planned effective flood damage prevention program has been initiated in Salina which includes protection from flooding by Mulberry Creek and Dry Creek. The existing flood protection channel includes the improvement of two miles of !Mulberry Creek channel between U. S. Highway 81 and the Union Pacific Railroad bridge . The major portion of Dry Creek has been diverted eastward into the Smoky Hill River from a point just south of the city. The remaining downstream part of the Dry Creek channel , approximately five miles , was straightened and leveed. This improvement is located between the Union Pacific Railroad Bridge and Magnolia Road. Obstructions to flood flows - There are no natural obstruc- tions to flood flows in the Mulberry Creek and Dry Creek flood plains. Obstructions hindering floodwater flow have been created by man 's continued encroachment onto the flood plain. In the study area , bridges are the most prominent man made obstacle. During periods of medium to high flows , trash and dehris tend to collect on bridge piers reducing the available waterway area and constricting the flow. Fiyure 1 , the Missouri Pacific Trestle over Dry Creek, shows debris beginning to collect on the pile bent piers. 5 } {. • i � - ti y L,j. 0 !

Flood Warning and Forecasting Services The following statement, furnished by the National Oceanic and Atmospheric Administration (NOAH) National Weather Service, des- cribes flood warning services available for the Salina area. The National Weather Service provides flash flood warnings for Mulberry Creek basin. This gives information locally for flood con- trol project operation and protective measures , thus providing a practical low cost method for reducing flood damage. The primary river fore- cast point is the wire-weight gage at the Coun- ty bridge about two miles west of State Street in Salina. Flood stage on Mulberry Creek in the vicinity related to the gage is about 26 feet. Flash flood warnings typically provide about 6 to 12 hours advance warning for the lower reach of Mulberry Creek. Forecasts are based on runoff computed from rainfall reports and radar observations. 6 Flash flood warnings based on National Weather Service Radar Observations : Areal coverage, intensity and precipitation area movement for the Salina vicinity is pro- vided primarily by the radar facilities located at Wichita and Concordia. The Wichita Weather - Service Office's -equipment is designed specif- ically for accurate determination of precipitation intensity. The basin is within effective oper- ating range of the station and the radar at Concordia. Although the Concordia local-use radar has more limited capability, the instal- lation has performed well during severe weather and flash floods . The Topeka Weather Service Office (WSO) , which is responsible for river services in the area, has direct communication with law enforcement offices and Civil Defense, as well as commercial radio and television stations . In areas where the time interval between rain and the ensuing flood is short , radar information and forecasts relayed immedi- ately to the news media and public service of- ficials in the area will result in substantial saving of life and movable property. Precipitation Stations : The flash flood reporting network for the Salina flood protection project includes the Mulberry Creek basin. At times of heavy rain reports are received from stations at Falun, Glendale, Brookville, Kanopolis , Lindsborg, and Salina FAA. The records for Falun and Glendale are not published, but are available at the Topeka WSO. River Reporting Stations : The river gage on Mulberry Creek was established in 1961 , and stage discharge relationship has been determined by the Geological Survey to fac- ilitate forecast procedures. These were financed by the Corps of Engineers for flood control pro- ject operation. River stage reports are obtained from a local observer when a rise is anticipated or is occurring. 7 Flood Fighting and Emergency Evacuation Plans Upon completion of the Federally sponsored flood protec- tion project , a plan for flood fighting was prepared and suggested for use. The plan is outlined in the Operation and Maintenance Manual Flood Project, Salina, Kansas. This activity relies mainly on the warning system of the National Weather Service described in the preceding paragraph. It should be emphasized that the lead time between the dissemination of flood warning and the crest of the flood could be short, necessitating rapid emergency measures to remove personnel and valuables from the flood plain. 8 PAST FLOODS Summary of Historical Floods Information obtained from newspaper accounts indicates a long history of flooding from Mulberry Creek and Dry Creek. Flo- ods have occurred numerous times since 1895 when the first event was reported. Notable flood events were May 1903 , August 1927, and October 1941 . Unfortunately, precise data regarding flood levels reached by these events at locations in the study area have not been documented. Flood Records Detailed information regarding flooding from Mulberry and Dry Creeks in the Salina area is somewhat limited since most of the flood plains lands in Salina have been in agricultural usage and flood events did not affect large numbers of people. Information on historical floods prior to the gage installation in March 1961 is based on research of newspaper accounts and interviews with local residents and officials . Records of water surface levels at the gage are available for flood events which have occurred since March 1961 . Flood Description The following composite accounts described three major events in Salina. Flood of October 20, 1941 - The flood of October 20, 1941 was caused by excessive rains concentrated south of Salina. Rainfall amounts varied from 2.94 inches at Salina to 11 .39 inches at Linds- borg. In the north part of Salina, approximately 50 block were inun- dated from Dry Creek floodwaters . Flood of July 11 , 1951 - Recorded rainfall amounts in Salina were 4.53 inches on July 10 and 4.05 on July 11 . Floodwaters from Mulberry Creek spread about a mile on each side of the channel . The north end of Salina was inundated again by floodwaters of Mul- berry and Dry Creeks . 9 Flood of May 1971 - The flood of May 22 , 1971 was caused by heavy rains in the headwaters of the Mulberry Creek Basin. Rain- fall varied from 3.2 inches at Bavaria to 4.8 inches at Glendale. Extent of flooding at various locations is shown in the Figures 2 through 4. Newspaper Accounts - Extracts from the Salina Journal are quoted below: SALINA JOURNAL May 26, 1903 - "The worst flood in the history of Salina is now raging and the entire portion of the city north of the Union Pacific and west of the Missouri Pacific tracks is entirely sub- merged. Portions of the city south of the Union Pacific tracks and west of Ninth Street , north of Ash are flooded and the waters are still ris- ing." May 27, 1903 - "The rise yesterday was from Mulberry; the rise today is from Dry Creek. The waters in Mulberry has receded and the creek is only about half filled, but Dry Creek has taken a great rise since morning and the water is rag- ing over the country southwest of the city tak- ing a course along the track into the northern part of the city and is spreading rapidly over the low lands." August 17, 1927 - "Water on Dry Creek at State Street now is 10 1/2 inches higher than at any other time this year. It has been at a stand- still for 30 minutes at 3: 15 o'clock." October 19, 1941 - "As a forerunner of what is expected to be the worst flood ever to strike Salina, Dry Creek lashed through its banks south of the city early this morning to spill angry waters into the already bankfull Smoky River. - - Unable to find an outlet, creek waters overflow- ed into east Salina and swirled the length of Fifth and adjacent streets in a mill race." 10 "By noon , from atop the United Life Building , half of Salina and all the surrounding country- side could be seen to resemble the land of 10,000 lakes . To the west flash flood waters rolled • down Dry Creek and into low fields spreading out as wide as two miles." July 11 , 1951 - "County Engineer, Hal Everett 's staff said they found a sheet of water starting two miles west of Salina and extending as far as they could see in the State Street road vicinity. They said it was water from the junction of Spring and Mulberry Creeks which join five miles west of the city." July 13, 1951 - "But Salina isn ' t out of the woods and waters yet . The furious Saline River highest in history north of Salina, could back water into the already swollen Mulberry Creek and Dry Creek, sending water into the north end." May 23, 19 1 - "U.S. 40 highway was closed to cars Monday afternoon one mile west of Salina. Overflowing Mulberry Creek covered an approach to a bridge west of the U. S . 40-State Street Road intersection." 11 • . t - Fig. 2. - International Harvester Company looking east from U. S. Hwy. 81 .

May 1971 . 13 FUTURE FLOODS Records show past flood events on Mulberry Creek have been relatively minor. By comparison much larger floods have occur- . red in nearby areas. Storms that produce these large floods on other streams could also occur in the Salina area , two examples of possible future floods , the Intermediate Regional Flood and the Standard Pro- ject Flood , are discussed . A flood the size of the Standard Project Flood represents the practical upper limits of expected flooding, although it is meteorologically possible for still larger floods to occur. Those the size of the Intermediate Regional Flood represent floods that may be expected to occur more frequently, although they will not be as severe as the Standard Project Flood. Unfortunately, when data for the Intermediate Regional Flood or the Standard Project Flood are presented , many people tend to ignore them in the mistaken belief that they could not occur during their lifetime. Actually, the chance of a flood the size of, or greater than the Intermediate Regional Flood occurring in the next 25 years is greater than one in four. It is possible for for such a flood to occur in successive years , even though the average over centuries would be only once in one hundred years . Intermediate Regional Flood The Intermediate Regional Flood is defined as a flood having an average frequency of occurrence on the order of once in 100 years , although the flood can occur in any year. Probability magnitudes of this type are usually developed from analysis of streamflow and precipitation records and the runoff characteristics of the stream basin. Unfortunately, the streamflow record for Mul- berry Creek is not sufficiently long to permit accurate analysis. Therefore, it was necessary to analyze precipitation and streamflow records of nearby basins having hydrologic , meteorologic and physio- graphic characteristics similar to those of the Mulberry Creek Basin. 14 The Intermediate Regional Flood discharge computed for Mulberry Creek is 37 ,000 cubic feet per second (c.f.s. ) . Compari- son of Intermediate Regional Flood depths at various locations in Salina can be made by referring to the stream profiles as shown on Plate 12 and elevations listed in Table 3. Standard Project Flood Severe as the maximum known flood may have been on any given stream, only in rare instances will it have reached what hydrologists regard as the maximum flood potential of the basin. The threat of flooding in excess of any past event must be recog- nized. The Corps of Engineers , in cooperation with the National Weather Service, has made broad and comprehensive studies based on the records of past floods and has evolved generalized procedures for estimating the flood potential of streams . These procedures have been used in determining the Standard Project Flood for Mul- berry Creek and Dry Creek. This flood is defined as a large flood that can be expected from the most severe combination of meteorological and hydrological conditions that is considered reasonably characteristic of the geographical region involved. Standard Project Flood discharges are 54,000 c.f.s . for Mulberry Creek and 10,800 c.f.s. for the Dry Creek area downstream of the diversion. Comparison of Standard Project Flood depths can be made by referring to the stream profiles as shown on Plate 12 and elevations listed in Table 3. Frequency For purposes of hazard evaluation, peak flow frequency curves can be used to illustrate the relative magnitude of flood- ing which has been experienced and could reasonably be expected in the future on both Mulberry Creek and Dry Creek. The May 1971 flood , which had an estimated discharge of 7 ,800 cubic feet per second is ranked as an 8-year frequency flood; 15 that is a flood occurring once every eight years , on the average. - Values for the 25, 50, and 75 year floods at key locations are listed below: Table 2 . Peak Flows for 25, 50, and 75 Year Floods 25-Year 50-Year 75-Year Flood Flood Flood Stream Location (c.f.s.) (c.f.s . ) (c.f.s . ) Mulberry Creek County Road (gage) 17,000 25,000 32 ,000 Dry Creek Mouth 3,400 5,000 6 ,400 Floods larger than the Standard Project Flood are pos- sible; however, the combination of factors that would be necessary to produce such floods would seldom occur. Consideration of floods of this magnitude would be of great importance to potential developers of the flood plain, if possible damages indicate the need of extreme- ly high assurance that the flood risk be eliminated. Hazards of Large Floods The hazards to life, health, and property possible from a flood the size of the Intermediate Regional Flood inundating Salinas flood plains is the concern of the entire community. Flood levels in existing commercial and residential areas would be much greater than any previously experienced. Floodwater flowing at high velocity and carrying floating debris would create conditions haz- ardous to persons and vehicles attempting to cross flooded areas . Generally, floodwater 3 or more feet deep and flowing at a velocity of 3 or more feet persecond can easily sweep a person off his feet, _ thus creating definite danger of injury or drowning. Rapidly ris- ing and swiftly flowing floodwater may trap persons in homes that are ultimately destroyed, or in vehicles that are ultimately sub- merged. Awareness of these hazards is of importance not only to those living in the flood plain, but to all in the community. 16 Flooded areas and flood damage - The flood plains in the study area that would be inundated by the Intermediate Region- al Flood and the Standard Project Flood are shown on Plates 4 through 11 . An index map showing the general relationship of these areas is found in Plate 3. Limits of the flooded areas as shown on the plates were determined from U. S . Geological Survey maps having a contour interval of ten feet and a horizontal scale of 1 inch to 2000 feet. Map features were supplemented, where necessary, by aerial photography and field investigations . The actual limits may vary from those shown due to map limitations , contour intervals , and changes in surface contour since mapping completion. Depths of flooding at any point can be determined by subtracting the ground elevation from the water-surface elevation indicated on the profiles . The approximate ground elevation can be determined from information indicated by contours on the map. Accurate elevations can be obtained by leveling to nearby bench marks . Obstructions - Salina's obstructive flood plain develop- ment described earlier will have an added serious significance dur- ing a large flood such as the Intermediate Regional Flood. Brush and debris washing downstream would reduce waterway openings by collecting on bridges , thus causing a damming effect. This dam- ming effect, depending on the degree of clogging, could cause great- er backwater depths with increased overbank flooding. Flood crests and pertinent elevations for the 24 bridges spanning the two water courses in the study area are listed in Table 3. For study purposes , it was assumed that limited clogging of waterway openings had occurred but that all bridge structures remained intact. Significant changes in these assumptions , im- posed by the varying conditions of future floods , could alter the flood crests and flood limits shown. 17 aj -o a 0 S.--0 r C7 L Li -1) N.

Factors influencing the velocity of flow include the size and shape of the available cross-sectional flow way, the condition of the stream channel , and the bed slope. Velocities generated by a flood of Intermediate Regional Flood magnitude are generally lower than those associated with the proportionately larger Standard Project Flood, but would still pose a substantial risk. As an indication of the velocities which could be generated by these floods , Table 4 shows average values computed at selected locations in Salina. In developed areas , velocities tend to increase as flood- waters are forced to flow around buildings and other obstacles not designed for water passage. Point velocities in these urban areas may be much higher than the averages shown in the table. Table 4.

A flood of Standard Project Flood proportions on 19 Mulberry Creek would reach its peak value in about 16 hours rising at a rate of about 1 .5 feet per hour. A Standard Project Flood on Dry Creek is estimated to rise at an average rate of 3.0 feet per hour and attain the peak flow in about 6 hours. The Mulberry Creek Standard Project Flood would be out of banks for about five days while Dry Creek would be out of banks for about two days . Photographs , future floods heights - Figures 5 through 8 show flood depths that would be reached by the Intermediate Reg- ional Flood and Standard Project Flood on facilities presently existing within Salina' s flood plains. 20 1 i � • STD.

Floods have two essential characteristics: The inundation of land is temporary; and the land is adjacent to and inundated by overflow from a river or stream or an ocean, lake , or other body of standing water. Normally, a "flood" is considered as any temporary rise in streamflow or stage, but not the ponding of surface water, that results in significant adverse effects in the vicinity. Adverse effects may include damages from overflow of land areas , temporary backwater effects in sewers and local drainage channels , creation of unsanitary conditions or other unfavorable situations by deposi- tion of materials in stream channels during flood recessions , rise of ground water coincident with increased streamflow, and other problems. Flood Crest - The maximum stage or elevation reached by the waters of a flood at a given location . Flood Peak - The maximum instantaneous discharge of a flood at a given location . It usually occurs at or near the time of the flood crest. Flood Plain - The relatively flat area or low lands adjoining the channel of a river, stream or watercourse or ocean, lake, or other body of standing water, which has been or may be covered by floodwater. Flood Profile - A graph showing the relationship of water surface elevation to location, the latter generally expressed as distance above mouth for a stream of water flowing in an open channel . It is generally drawn to show surface elevation for the crest of a specific flood, but may be prepared for conditions at a given time or stage. 23 Flood Stage - The stage or elevation at which overflow of the natural banks of a stream or body of water begins in the reach or area in which the elevation is measured. Flow Line - The minimum stage or elevation at which flow occurs in a stream. Head Loss - The effect of obstructions , such as narrow bridge openings or buildings that limit the area through which wa- ter must flow, raising the surface of the water upstream from the obstructions. Intermediate Regional Flood - A flood having an average frequency of occurrence in the order of once in 100 years although the flood may occur in any year or even in successive years. It is based on statistical analyses of streamflow records available for the watershed and analyses of rainfall and runoff characteristics in the general region of the watershed. Left Bank - The bank on the left side of a river, stream, or watercourse, looking downstream. Low Steel (or Underclearance)- See "Underclearance. " Right Bank - The bank on the right side of a river, stream, or watercourse, looking downstream. Standard Project Flood - The flood that may be expected from the most severe combination of meterological and hydrological conditions that is considered reasonably characteristic of the geographical area in which the drainage basin is located, excluding extremely rare combinations. Such floods , as used by the Corps of • Engineers , are intended as practicable expressions of the degree of protection that should be sought in the design of flood control works , the failure of which might be disastrous. 24 Underclearance - The lowest point of a bridge or other structure over or across a river, stream, or watercourse that limits the openings through which water flows. This is referred to as "low steel " in some regions. 25 ACKNOWLEDGEMENTS Assistance and cooperation of the National Oceanic and Atmospheric Administration (NOAA) National Weather Service, the U. S.
