Executive Summary The use of a levee and flood gate system in Jefferson City to reduce flooding in the Capitol Complex area was evaluated for feasibility by HDR Engineering. As a part of this process analyses of flood hydrology, hydraulics and coincident flow conditions of the Missouri River and Wears Creek were performed. Use of the levee system/flood gate alternative was found capable of effectively reducing flooding within the complex. However, the primary drawback of this system was found to be the quantity and sizes of pumping stations required to pass Wears Creek flows past a closed flood gate into the Missouri River. The total costs of such a system would likely be in excess of $20 million. Based upon what is known about annual costs of damages in the Capitol Complex, it is doubtful that this level of expenditure could be justified. Methods were found for reducing the pumping costs associated with this control system but they resulted in a corresponding decrease in the level of flood protection. Other alternatives were identified during the study as potentially able to reduce the flooding threats. While not studied in detail these methods include: A) Wears Creek Bank Storage and Protection. This alternative could take advantage of the parking lots along Wears Creek and use them for increased detention. This could include terracing the parking lots and including floodwalls between the parking lots and the buildings. B) Railroad Embankment Capacity Upgrade. The constriction caused by the Railroad Culvert is the greatest single factor controlling Wears Creek flood elevations upstream. Enlargement of this opening could substantially decrease flooding caused by Wears Creek although it would not increase protection from Missouri River. C) Upstream Detention Storage._Detention upstream of the developed Wears Creek Basin could potentially reduce Wears Creek peak flows, thereby reducing the probability of flooding in the capitol area. State of Missouri -I-1/15101 Wears Creek Flood Control HDR Engineering, Inc. D) Tie Back Levees. Levees can be placed around the Capitol area which provide protection from both Missouri River flood levels as well as Wears Creek flooding. While this type of infrastructure may require a greater investment in levees and flood walls, it will minimize the need for large pump stations due to the small interior drainage area. E) Protect/Move Sensitive Property. The costs to move sensitive property, or to individually protect sensitive property, may be less than constructing physical barriers to keep out all flood flows. F) Combinations ofthe above. Future studies need to review the potential for combining portions of the alternatives presented above in a cost-effective manner. Regardless of the potential solution ultimately selected for additional study, the coincident flow analysis of the basin provides insight into the flooding problems of the basin that will be useful for future evaluations. Rigorous development of the probabilities associated with the coincident flow of Wears Creek and the Missouri River had not been previously performed.

Introduction Over the last century, downtown Jefferson City has experienced extensive damage due to flooding. The flooding has been a result of the Missouri River water levels as well as the water levels along Wears Creek. Flood flows, profiles and flooded areas for the various frequency events on Wears Creek used within this study have been based on FEMA's report, which are based on an assumption of 100 percent coincidence with the Missouri River flows. 2.1. Study Area The study area includes the right bank Missouri River floodplain in Jefferson City, Missouri and the floodplain of Wears Creek, which enters the Missouri River at approximately River Mile 143 .3. The Jefferson City gauge on the Missouri River is located at mile 143.9. The Missouri River floodplain, right bank extends approximately from mile 143.2 to mile 143.7 on the Missouri River and backwater from floods on the Missouri River extend upstream into the Wears Creek floodplain about 1.75 miles to the Highway 54 Bridge across Wears Creek. Flooding also occurs upstream in the North and East branches of Wears Creek. 2.2. Purpose The ultimate purpose of this project was to evaluate the feasibility of additional flood control measures capable of minimizing flood damage near the mouth of Wears Creek Basin in the City of Jefferson City, Missouri Capitol Complex area. Hydrologic and hydraulic investigations were performed to identify these measures and evaluate their effectiveness. Measures which were considered and evaluated include flood gates, levees, and pumping stations designed minimize flooding near Capitol Complex. Other alternatives were identified but not evaluated in detail. While the feasibility of reducing overall damages within the Capitol Complex was the primary goal, of particular concern was the Truman State Office and Health Lab/EDP. State of Missouri -3-1115101 l _J Wears Creek Flood Control HDR Engineering, Inc. These buildings have first floor elevations of 563.5 and 560.0 msl., respectively. The Missouri River stages for the 1 00-year and 500-year events at the mouth of Wears Creek are 557.4 and 560.0 msl. These buildings would therefore be subject to flooding at recurrence intervals greater than or equal to the 500-year event from the Missouri River. Studies by the US Army Corps of Engineers (COE) have identified the potential for increases in Missouri River Flood elevations over the next 30 years. These estimates raise the 1 00-year Missouri River flood event by up to 2.3 feet. This change makes the State Offices target elevations subject to inundation by events as frequent as a 1 00-year event. Increase levels of risk due to this increase are also evaluated. 2.3. Methodology In order to model the complex nature of the Jefferson City downtown area, several different steps were followed. An HEC-RAS (US Army Corps of Engineers hydraulic model) model of Wears Creek was developed to determine the relationship between water elevation and flow rate along the Wears Creek profile. A coincident flow analysis was performed to evaluate the return period of stages in the downtown region of Jefferson City for existing, future, and proposed conditions. Finally, HEC-IFH (US Army Corps of Engineers interior drainage model) was used to model the hydrology and storage related pending in response to proposed levees and gates. Two-foot contour mapping was used for establishing stage storage relationships. In order to ensure a constant point of reference, all elevations were compared just downstream of State Highway 50 in order to evaluate the effects on flooding of the different options. This report describes the procedures followed, the assumptions made, results, and recommendations for further study of potentially feasible flood control options. The cost of the levee and gate option is conceptually evaluated and included.

The U.S. Army Corps of Engineers (COE) provided flood stages for the Missouri River in draft studies for the Missouri River Levees. Wears Creek flood flows provided by the COE were used for the Wears Creek flood flow frequencies (COE, 2000). Several studies have been performed by the COE on the trend of increasing stages for historic discharges in the Missouri River. These studies resulted in higher stages under future conditions, up to 2031 ft-msl. The impacts of these higher projected stage elevations were also investigated. Throughout this report, present conditions are referred to as 1997 stages. Future conditions are referred to as 2031 stages. Proposed conditions refer to hydraulics due to potential alternatives such as levees, gates and pumps. 3.1. Provided Information 3.1.1. Wears Creek Flood Frequency COE provided the initial flood frequencies used for Wears Creek. These corresponded to email correspondence with the COE, as well as the values included within the hydraulics model provided by the COE. The 2-year and the 5-year flow frequencies were extrapolated from the provided flows using plotting positions on logarithmic probability paper. The Wears Creek flow frequencies and the extrapolated curves are below in Table 1 and Figure 1 .

In the COE report, 2.33 feet was added to flood stages to compensate for the trends in increasing stages for future stages on the Missouri River. This stage adjustment was made across the board on the 10, 50, 100, 500, 1000, and 2000-year flood elevations in tables B2.35-B2.40 of the COE, 1999 report. It is likely that this value may vary between recurrence intervals. However, since no other published information was available, the 2.33 additional feet was added to all events evaluated within this report. The current and future stages are shown in Table 2.

A stage duration curve represents a description of the percentage of time that a river stage is exceeded at any given time. It is important to recognize that this percentage is different than that used to describe event recurrence intervals. The stage-duration curve is presented in Figure 2.

Existing Conditions Hydraulic Model An HEC-RAS model of Wears Creek was provided by the COE at the beginning of the project. This model was used as the base for subsequent Wears Creek hydraulic modeling. It was annotated on the model received that it was not complete and should be checked before application. The model appeared to be a translation of an HEC-2 to an HEC-RAS model. Cross-sections were checked for evident errors including missing high or low chords, incorrect or missing ineffective flow areas, and mismatched manning's "n" values.

The model was substantially revised and updated to accurately represent hydraulic conditions at bridge crossings as well as overbank conditions. Modifications were based upon available mapping and descriptions of river crossings. No field verification was performed for this analysis. 3.2. Stage Frequency Analysis Coincident flow analysis was performed to evaluate the effects of the dual probability of flood flows on Wears Creek, tailwater on the Missouri River, and independent flood stages on the Missouri River. The resulting stage frequencies were then compared to the reduced stage frequencies of the various alternatives to estimate the improved level of protection provided. 3.2.1. Coincident Flow Analysis The first step to computing the stage frequencies is to perform a coincident flow analysis on Wears Creek with respect to Missouri River stages (tailwater elevation). Procedures for coincident flow analysis are provided in the lecture notes "Hydrologic Probabilities, Workshop VII, Coincident Frequencies" developed by the COE as part of their internal training program. A key assumption of this theory is that the Missouri River stages and the Wears Creek flows are independent and therefore the probability of tail water and flood flows occurring at the same time can be computed using total probability theorem. Though some dependency exists between the two variables, the relatively large size difference between the Missouri River and Wears Creek basins makes the assumption of independence reasonable. The procedure required three pieces of information: the flood frequency of the tributary, the stage duration curve of the receiving stream, and the relationship between the flow tributary flood frequencies and the receiving stream stages. The Wears Creek flood frequencies and Missouri River stage-duration curve are shown in the provided information section. State of Missouri -9-1115101 -~ I Wears Creek Flood Control HDR Engineering, Inc. The elevations at State Highway 50 due to the flood frequencies on Wears Creek and the Missouri River stages were modeled using HEC-RAS.

The HEC-RAS runs show that the Wears Creek Stale of Missouri -10-1115101 .. , .. l _.l l J Wears Creek Flood Control HDR Engineering, Inc. flood profiles are controlled by the culverts under the railroad embankment near the mouth of Wears Creek rather than the Missouri River, until the culverts are submerged. Because only 6 to 11 percent of the Missouri River daily stages submerge the culverts, the stages at State Highway 50 are usually controlled by Wears Creek Flows.

This is less than the 2.33 feet of increased Missouri River stage. 4. Analysis of Alternatives 4.1. Alternatives and Assumptions The goal of this study is evaluate the feasibility of constructed measures in reducing the frequency and extent of flood damage. The alternatives evaluated focused primarily on a levee and floodgate system designed to minimize the impact of Missouri River flood stages causing flooding within the Capitol Complex. The levee and floodgates provide this protection by providing a physical barrier between the Missouri River and Jefferson City. However, complications arise when determining how to avoid flooding of areas interior to the levees by flows from Wears Creek. This may be accomplished by State of Missouri -14-1115/01 I I ·-' ) ' I J I ~) I _j I -4 ' ' I ' I I __ , _j Wears Creek Flood Control HDR Engineering, Inc. providing pumps to discharge interior flows past the levee system into the Missouri River. A key feature then is the efficient sizing of the pumps required to pass this flow. In order to determine the feasibility of this overall system, the extent of the protection, the frequency of remaining potential flood damage, the size of the levees and gates, and size of the pumps need to be determined. The primary variables in the design of this system include the height of the levee, the operating plan of the floodgates and the pumping system. Optimal final design of these features is well beyond the scope of this study, therefore a series of assumptions were made and evaluated as to potential feasibility. Most of this iterative procedure revolves around gate operation and pumping rates since the setting of levee heights is normally more straight forward. 4.2. Interior Drainage Modeling The evaluation of this system used portions of the flow frequency analysis, the stage discharge relationship derived from the HEC-RAS model, the stage storage relationships of the Wears Creek basin, operating assumptions for gate and pump operation and the COE Interior Drainage Model, HEC-IFH. The model was used to generate the flows and hydrology of Wears Creek and evaluate the ponding in the basin in response to Missouri River stages and closed floodgates. The model ultimately determined the effects of gates and levees on Capitol Complex flood stages. Levees investigated were assumed to be placed at (as modifications to the existing structure) or near the existing railroad embankment at the mouth of Wears Creek. 4.2.1. Basin Runoff Data The SCS Curve Number method was used in HEC-IFH to estimate flow rates and volumes. The required parameters for the SCS method are the basin size, curve number, percent impervious, type of unit hydro graph and time of concentration. State of Missouri -15-1115101 Wears Creek Flood Control HDR Engineering, Inc. The basin area was calculated using the Delorme mapping software as 14.27 mi2• The total area was verified by delineation on the aerial photo. The percent impervious was calculated using the aerial photo in GIS and delineating the different land uses. Using a weighted average the total impervious area is estimated at 65%. Delineation of sub- watersheds is shown in Figure 8. Land use characteristics ofthese basins are presented in Table 5. Table 5: Estimate Land Use Areas Basin Area (sq. mi.)

Wears Creek Flood Control HDR Engineering, Inc. The curve number was calculated from the types of soil in the different branches of the Wears Creek Basin. The north and east branch have a soil type B which is approximately 35% of the total basin. The Frog Hollow Branch (main branch) has a soil type classified as soil type C. This is the remaining 65% of the basin. The soil types were pulled from the Master Plan for Wears Creek, written in 1970. SCS lag-time was required for the IFH program. The time of concentration was calculated using SCS methodology. SCS lag-time was calculated by multiplying the time of concentration by 0.6. This was taken from section 9.23 in the Handbook of Hydrology written by David R. Maidment. The SCS lag-time was calculated to be 2.1 hours. This value was input in the Basin Runoff Data section of IFH. The unit hydrograph used was the SCS Dimensionless. 4.2.2. Exterior Stage Elevation HEC-IFH requires the exterior stage elevations to estimate the pumping head. The exterior stage elevations used are from the COE-Draft Report for the Missouri River written in 1999 and are listed in the "provided information" section. 4.2.3. Outlet Data The outlet is considered to be the downstream face of the Railroad culvert. The outlet data has been developed from the COE HEC-RAS data from 1980. Two concrete boxes (2-18'x12') with a manning's coefficient of0.02 are located under the railway embankment. The inlet and outlet for the two boxes are at an elevation of 528 feet. Total length of the culverts is 94 feet. The entrance loss for the box is 0.5. The top of the embankment covering the culvert is at an elevation of 554 feet, which is the top of rail elevation for the Missouri Pacific Railroad. Stale of Missouri -17-111510/ -, ' j Wears Creek Flood Control HDR Engineering, Inc. 4.2.4. Stage-Storage Data The stage storage data is based upon 2-foot contour lines of Jefferson City. The 3-D analyst extension for Arc View determined the areas at different elevations. The elevation-area data was checked by tracing the contour lines in Arc View. This data was used to determine the elevation of pending behind the levees following closure of the flood gates. 4.2.5. Precipitation Data The precipitation data is from TP-40. The 500-Year event precipitation data was extrapolated using a log curve from the TP-40 data. The precipitation data used is presented in Table 6.

Levee System Analysis 4.3.1. Description The levee options investigated include modification of the existing railroad embankment at its present elevation by fitting flood gates through the opening, and raising the levee as well as the railroad embankment to an elevation sufficient to keep out the Missouri River 500-year flood stage. The objective of the various pumping schemes is to eliminate damages related to the Missouri River flooding while keeping ponded flood elevations State of Missouri -18-1115101 ~ : i ; I i -, I J --, ~ ··--' ' i .J I ·-' l I _j _j ! _j Wears Creek Flood Control HDR Engineering, Inc. due to Wears Creek flows at or below the existing flooding elevations. This approach ultimately provides an overall reduction in frequency of flooding within the Complex. Assumptions used in the evaluation of various alternatives include: a) Reduce the damage elevation ofthe 100yr Wears Creek flow to 556.0 ft. b) Reduce the damage elevation of the 500 yr Wears Creek flow to 558.0 ft. c) Reduce the damage elevation of the 100yr Wears Creek flow to 556.0 ft; considering the probability that the gates will be closed due to 1997 Missouri River stages. d) Reduce the damage elevation of the 500 yr Wears Creek flow to 558.0 ft considering the probability that the gates will be closed due to 1997 Missouri River stages. e) Reduce the damage elevation of the 100yr Wears Creek flow to 556.0 ft considering the probability that the gates will be closed due to 2031 Missouri River stages. f) Reduce the damage elevation of the 500-yr Wears Creek flow to 558.0-ft considering the probability that the gates will be closed due to 2031 Missouri River stages . Figures 9 and 10 show five different pumping schemes and their effect on the elevations in reference to the return period of the flow on Wears Creek. Figure 9 shows elevations starting to level off at 554 ft-msl because of overtopping of the existing railroad embankment. Figure 10 shows elevations with a levee elevation exceeding 561.0 feet, built to hold in the Missouri River 500-year flow.

Ponded water occurs when the gates are closed and Wears Creek floods. The levee gates during this analysis close when the Missouri River stage exceeds 539ft (1 foot short of the top of culvert at the Railroad embankment). By taking into account the chance that Wears Creek flooding occurs when the gates are closed, the probable volumes behind the levee are decreased. Because the future river stages are higher than the current stages, the chances of the gates being closed is higher during the future conditions, and results in greater flood volumes. Figures 11 through 13 illustrate how the probabilities change for the gate-closed conditions in reference to the different pumping rates. 565.0 560.0 555.0 550.0 c: 545.0 & a 540.0 535.0 530.0 525.0 520.0 0 " '/ 0 ... / -Galea dOsed by 2031 Elevation& Pondlng Elevations vs. Probability of Flow 4400 eta of Pumping ~ ---/ / // E..CMdanca Fr-.quency (%) ~ / ? v "' 0 - N -on 0 0 ~ 0 0 -Gates dosed by 1997 Elevation& -Rega!ISess ot Gate Closed Probability Figure 11: Effects of gates closed on elevation frequency for 4400 cfs of pumping Stat e of Miss ouri -2 1-1115101 _.J Wears Creek Flood Control 565.0 560.0 555.0 Pondlng Elevations va.

Table 7 shows the pumping required to maintain ponding elevations below 556.0 for 100 year and 559.0 ft for 500 year Wear Creek flows, depending on the probability associated with the gates closed.

The pumping required to reduce all Wears Creek flood elevations to within the banks, with levees in place is fifteen 500- cfs pumps. However, this can be reduced to 11 to 12 pumps if coincident flow concepts are taken into account. The analysis shows that with the closure gate in operation flood stages for the selected frequency events increase over pre-project conditions. State of Missouri -23-1115101 Wears Creek Flood Control HDR Engineering, Inc. 4.3.2. Effects on Flood Frequency As is shown throughout the report, the difference between flood damages from the 1997 and the 2031 stages on the Missouri River is significant. Regardless of the ultimate solutions identified, this fact should be used to ensure that the 2031 stages be the design events of future studies on the basin. 4.3.3. Conceptual Costs Conceptual level costs were developed and presented in Table 8. These costs are very rough and are primarily intended for use in comparison studies only. Additional design work would be required to develop cost estimates within 10%-to 15% of actual. They are based on the idea that the capitol complex will be presented to the 500-year event under future elevated Missouri River bed conditions. This will require a pumping capacity of 5900 cfs or roughly 12 500-cfs pumping stations. Table 8: Conceptual Cost Evaluation (Net present value) Component Cost Pumps $15 -$22 million Levee $5 million Gates $1.5 million O&M $0.5 million Total $22-$29 million 5. Conclusions and Recommendations As shown in Table 8, the cost associated with the construction of the levee and the pumps is significant. Other alternatives may offer similar protection at a less cost. Several alternatives are listed below: State of Missouri -24-1//5/0/ ! i .J __ ; -l l i . i .J I _.) I _j ! --1 -' i I _j I I .> J Wears Creek Flood Control HDR Engineering, Inc. A) Wears Creek Bank Storage and Protection. This alternative could take advantage of the parking lots along Wears Creek and use them for increased detention. This could include terracing the parking lots and including floodwalls between the parking lots and the buildings. B) Railroad Embankment Capacity Upgrade. The constriction caused by the Railroad Culvert is the greatest single factor controlling Wears Creek flood elevations upstream. Enlargement of this opening could substantially decrease flooding caused by Wears Creek although it would not increase protection from Missouri River. C) Upstream Detention Storage._Detention upstream of the developed Wears Creek Basin could potentially reduce Wears Creek peak flows, thereby reducing the probability of flooding in the capitol area. D) Tie Back Levees. Levees can be placed around the Capitol area which provide protection from both Missouri River flood levels as well as Wears Creek flooding. While this type of infrastructure may require a greater investment in levees and flood walls, it will minimize the need for large pwnp stations due to the small interior drainage area. E) Protect/Move Sensitive Property. The costs to move sensitive property, or to individually protect sensitive property, may be less than constructing physical barriers to keep out all flood flows. F) Combinations o(the above. Future studies need to review the potential for combining portions of the alternatives presented above in a cost-effective manner. Regardless of the potential solution ultimately selected for additional study, the coincident flow analysis of the basin provides insight into the flooding problems of the basin that will be useful for future evaluations. Rigorous development of the probabilities associated with the coincident flow of Wears Creek and the Missouri River had not been previously performed.
