SECTION 1.0 - EXECUTIVE SUMMARY
1.1 GENERAL INFORMATION
Burns & McDonnell Engineering Company was authorized by the City of Jefferson, Missouri to study the
area of the Moreau River South Watershed located within the existing corporate limits and potential
future area of annexation lying north of State Highway C and new State Highway 179 (see Exhibit 1).
The main stem of the Moreau River was specifically excluded from the scope of this Project. The area
included approximately 6.8 square miles of drainage area (4360 acres), encompassing portions of the City
of Jefferson, Missouri and unincorporated areas of Cole County. The Moreau River South Study Area
Interim Report is part of the third phase of the City of Jefferson Stormwater Management Plan.
The purpose of this study is to perform a hydrologic analysis of these areas under existing and future
development conditions, and a hydraulic analysis of the stormwater drainage system. The results of these
analyses have allowed floodplains to be drawn for these areas and for culvert and pipe flow demands to
be better understood. Recommendations for improvements will be made in the fourth phase of this
project.
1.2 METHODOLOGY
1.2.1 Data Collection
Data about the watershed was collected in a geographically referenced database, ESRI’s Geographical
Information System (GIS) mapping software. This information was used to generate the input and store
the output from XP-SWMM 2000 stormwater modelling software and the U.S. Army’s Corps of
Engineers HEC-RAS river analysis program. The GIS database serves as both an inventory of the
stormwater system and an easily accessible repository of the results of this study.
1.2.2 Hydrology
The watershed was classified for soil type, vegetative cover, current and future landuse and divided into
subsheds. Hypothetical storms with return periods from two to one hundred years were used to simulate
stormwater runoff and generate flow hydrographs from each subshed for both existing and future landuse
conditions.
1.2.3 Hydraulics
Downstream routing of the runoff hydrographs through culverts and pipe systems was computed, and
peak flows were evaluated in the major channels and large culverts of the watershed to calculate water
surface elevations. Floodplains were then drawn for the 100-year existing and future conditions.
1.3 SYSTEM PERFORMANCE
The elements of the watershed were evaluated for their ability to convey the stormwater from these
various storm events. The simulations indicate that in the large channels there are a small number of
buildings threatened by floodwater in the 100-year event, that three of the large culverts are overtopped in
Stormwater Management Plan
City of Jefferson, Missouri

the 10-year or 25-year event, and thirty-one percent of the smaller culverts and small systems surcharge in
the 10-year event.
These results will be evaluated and recommendations for improvements will be developed with input
from the City and County, complaints, questionnaires, and field investigations in Phase 4 of this study.
When these results are evaluated it is probable that there will be some fine-tuning of the hydraulic
analysis. This fine-tuning may result in some modifications to the water surface elevations reported in
this interim study, hence the final report may contain a few water surface elevations that supersede those
reported in this document.

SECTION 2.0 - INTRODUCTION
In the year 2001, the City of Jefferson embarked on a program to develop stormwater master plans for
each of the City’s major watersheds. This program is based on a recognized need to upgrade existing
inadequate stormwater conveyance systems and to plan for new systems in developing areas. The
economic well being of the City depends on its ability to attract and retain business and industry as well
as residents to live in the City. Part of the City’s ability to attract business and residents depends on its
ability to provide adequate services such as drinking water, sewers, transportation and stormwater
management.
Historically, stormwater management has only been a concern when major floods occur. With increased
development and the associated increases in impervious area due to development, the volume of runoff
from rainfall and the frequency of flooding have correspondingly increased. This has caused the City to
focus its attention on the need to provide improved stormwater management facilities in all areas of the
City.
2.1 PROJECT TEAM
Burns & McDonnell Engineering was the prime contractor for this study. Central Missouri Professional
Services, Inc. conducted the field surveys.

2.2 STUDY AREA
The area of study for this report is limited to the Moreau River South Watershed located within the
existing corporate limits and potential future area of annexation lying north of State Highway C and new
State Highway 179 (see Exhibit 1). The area includes approximately 6.8 square miles of drainage area,
encompassing portions of the City of Jefferson and unincorporated areas of Cole County. The main stem
of the Moreau River is specifically excluded form the scope of this Project.
2.3 PURPOSE
The Moreau River South Study Area Interim Report is part of the third phase of the City of Jefferson
Stormwater Management Plan. The purpose of this study was to model the existing and future surface
conditions and the ability of the storm drainage system to convey the runoff from various events.
2.4 SCOPE OF SERVICES
This report presents a description of the services completed for the hydrologic and hydraulic modelling
under existing and future surface conditions for the Moreau River South watershed. The report will
Stormwater Management Plan
City of Jefferson, Missouri
4 March 4, 2005
include supporting text, tables, figures, exhibits, computer models, computer output and appendices to
accurately present the services completed. The following major tasks are included in this study:
2.4.1 Information Review
A comprehensive review of the existing information and studies provided an understanding of existing
conditions and the improvement plans previously proposed and/or implemented. This task involved the
assemblage, review and organization of existing mapping, records, reports, ordinances, criteria and
floodplain studies available from the City, County and other sources.
2.4.2 Field Investigations and Inventory
A survey of the watershed and drainage system was conducted within the study area. The purpose of the
field investigation was to obtain specific information on existing piping systems, channels and structures.
Observations were recorded in a standardized format and supplemented with photographic records. Data
gathered included the following items:
• Measurement of hydraulic parameters
• Logging of information in a GIS-compatible format.
2.4.3 Existing System Evaluation
Hydrologic and hydraulic models were developed for drainage system components (structures and/or
natural and improved channels) beginning where 24 inch or larger culverts were in place. The stormwater
system was evaluated under the following two (2) conditions:
• Existing conditions with the existing storm sewer system – This plan represents
conditions as currently observed within the watershed.
• Future surface conditions with the existing storm sewer system – This plan
represents conditions that could occur as the watershed develops without making
improvements to the existing sewer system.
2.4.4 Watershed Mapping
The previous FEMA Flood Insurance Study was published October 6, 1981. Since that time, the
watershed has experienced considerable urbanization. Additionally, advances in hydrologic and
hydraulic modelling, the introduction of Geographical Information Systems (GIS) and new aerial
topography allow a more accurate representation of floodplains.
For this study, new floodplains were developed for the 100-year storm event for existing and future
surface conditions. It was not within the scope of this study to prepare a FEMA map revision.

3.3 FIELD INVESTIGATIONS
Elevation and location surveys of the stormwater drainage system were conducted in conjunction with
this study. Surveys collected the hydraulic data for drainage structures within the study area identified by
the Engineer, City and County Staff. Significant drainage structures were generally identified by the
following criteria:
• 24 inch diameter (or equivalent capacity) or larger.
• Major structures (bridge or culvert) having tributary areas of 160 acres or greater.
• Hydraulic structures within close proximity of buildings or other significant land objects.
• Other structures of interest identified by City and County staff.
A combination of Global Positioning Systems (GPS) and total station technology was used to obtain the
required elevations for surveyed structures. Elevation information was collected using a data collector.
Additional information, such as shape, material, condition, type, etc. was recorded on standardized forms.
The data collected at the various types of drainage structures is listed below.

SECTION 4.0 - HYDROLOGIC MODELLING
4.1 INTRODUCTION
The hydrologic analysis for this study was done with XP-SWMM 2000 stormwater management
modelling software (Version 8.52) from XP Software Incorporated. The software generates runoff
hydrographs at desired locations in the watershed for specific storm events based on the specific input
parameters for each component of the process. For this study, the RUNOFF module was used to generate
hydrographs for return periods of 2, 5, 10, 25, 50 and 100 years. Parameters used in the hydrologic
modelling include the Soil Conservation Service’s (SCS) Type II hypothetical storm generated from
rainfall frequency data for precipitation, the SCS curve number for the loss rate, the SCS dimensionless
unit hydrograph, and physical characteristics of each subshed.
4.2 WATERSHED DELINEATION
4.2.1 Subarea Boundaries
The Moreau River South Watershed was divided into subwatershed areas. The first step of subarea
boundary delineation divided the watershed into areas of approximately 160 acres at the upper reaches of
the conveyance system. The second step defined many areas much smaller than 160 acres at the upper
reaches. These smaller areas are needed to accurately model the hydrology for the enclosed systems. All
subareas were based on hydrologic and/or hydraulic features, such as terrain, channels, confluences, and
culverts or bridges within the Moreau River South Study Area. Exhibit 2 shows the subareas associated
with the Moreau River South Watershed. Each subarea was assigned a unique identifier in the hydrologic
model.
4.3 PRECIPITATION
4.3.1 General
Every storm event that occurs within a watershed is unique. Some storms are short and intense and
deposit a large amount of rainfall in a short period of time. Other storms have a constant rainfall intensity
that occurs over a long period of time. Because there is no means to predict the characteristics of a given
storm, a synthetic or design storm is typically used for hydrologic modelling. A design storm is simply
an assumed distribution of rainfall over a given amount of time.
4.3.2 Rainfall Distribution
For this study, a Soil Conservation Service (SCS) Type II rainfall distribution was used. The SCS
distribution was prepared for use in the United States for storms of 6 and 24-hour durations. The Type II
storm distribution is applicable to central Missouri. The distribution of rainfall is shown in Figure 4-1.
Stormwater Management Plan
City of Jefferson, Missouri
9 March 4, 2005
4.3.3 Rainfall Depths
Technical Paper No. 40 Rainfall Frequency Atlas of the United States (TP-40) was used to determine the
rainfall depths for various storm recurrence periods and various time periods. The TP-40 based data is
shown in Table 4-1 below:

4.3.4 Rainfall Duration
The design storm used in the analysis of a drainage system is the pattern of rainfall over a specific
duration for a given return period. The duration that puts the greatest demand on the system is termed the
“critical storm duration” and is roughly equal to the time of concentration of the watershed. Time of
concentration, Tc, is the time at which the entire drainage area begins to contribute runoff. It may also be
defined as the time required for runoff to flow from the farthest point in the watershed to the outlet. The
“critical” duration represents the minimum time required to insure that runoff from all parts of the
drainage area is included in the peak discharge measured at the outlet. The design storm duration used in
this project was the 6-hour storm for all return periods.
4.4 RUNOFF
4.4.1 Soils
NRCS soils information used for calculating hydrologic parameters was obtained in an electronic format
from the Missouri Spatial Data Information Service (MSDIS)1. According to the source, soil scientists
manually compiled field maps on 1:24000 scale one-third-quadrangle ortho-photography in the 1927
North American Datum (see Exhibit 3).
4.4.2 Land Use
4.4.2.1 Existing Conditions
In order to determine the parameters needed for the hydrologic model, a land use map was developed for
the watershed (see Exhibit 4). Land use parameters influencing runoff were estimated from aerial
photography and field observations. The curve numbers shown in Table 4-2 were taken from TR-55,
Urban Hydrology for Small Watersheds2. Curve numbers represent antecedent moisture condition II.

4.4.2.2 Future Surface Conditions
Hydrologic parameters for the future surface condition were based on planning information provided by
the City and engineering judgment (see Exhibit 5). Several areas were assigned land uses equivalent to
their proposed zoning designation. Additional criteria used to fill out the future surface condition map are
as follows:
• Adjacent to state routes, a 330’ strip each side of roadway defined as commercial.
• Adjacent to major intersections involving state routes or major arterials, a 660’ strip on each side
of each intersecting roadway defined as commercial while extending 660’ in all directions from
the intersection.
• For large contiguous areas that have been developed with multiple residential properties, define
these areas as residential (low, medium or high density where appropriate).
• For existing or developing subdivision areas, define with no change for the future surface
condition.
Stormwater Management Plan
City of Jefferson, Missouri
12 March 4, 2005
• On presently undeveloped ground, define as undeveloped if in a flood plain or zoned as open
space, park or recreational. In all other cases, define as low or medium residential based on the
area topography, i.e. as the ground slope increases the development decreases to none.
4.4.3 Loss Method
The SCS Curve Number Loss Method was utilized according to the technical guidelines prescribed by the
TR-55 Manual. Based on the combinations of soils types and land use characteristics shown in Table 4-
2, a weighted runoff curve number was estimated for each subarea. This was done by subdividing each
subarea into polygons representing every combination of land use and soils type. With a curve number
assigned to each polygon, a weighted curve number was calculated for the entire subarea as follows.
Weighted Curve No. = ∑(Ai x CNi) / ∑AI
Where
Ai = area of each shape

4.4.6 Hydrographs
For each subarea, a flow hydrograph was calculated using the SCS dimensionless curvilinear unit
hydrograph method.
4.4.7 Conveyance Routing
XP-SWMM performs hydraulic flow routing for open channel and/or closed conduit systems. At the
heart of this graphical input-output interface, is the EPA-SWMM 4.4h engine. The Hydraulic module
receives hydrograph input from the Runoff module and performs dynamic routing of stormwater flows
through the storm drainage system to an outfall. The program will model branched or looped networks,
backwater conditions, free-surface flow, pressure flow or surcharge, flow reversals, flow transfer by
weirs, orifices and pumps, and storage facilities.
Conveyance elements (channels, pipes, etc.) were given a value for the Manning’s "n" coefficient, which
is a measure of the roughness of the element and is used in both XP-SWMM and HEC-RAS to calculate
flows and water surface elevations. These "n" values were selected using field observations, project
photos, aerial photos, and engineering judgment. Additionally, selected channels were idealized and
modeled with trapezoidal or 8-point cross-sections within the Hydraulic module. Where trapezoidal cross
sections were used to represent both channel and overbank a composite "n" value was derived from a
preliminary 100-year storm processed in HEC-RAS.
Overland flow channels were used above all closed conduits to eliminate ponding and facilitate the
movement of surface flow downstream allowing for more conservative peak flows. Each overland flow
channel simulated a cross sectional shape appropriate for its location. This cross sectional shape could
represent a roadway sag over a culvert, a gutter section, a backyard swale, or a side yard swale between
properties.
4.5 MODEL CALIBRATION
Moreau River South is an ungaged stream therefore it is not possible to calibrate the model by definition.
However, it is possible to ascertain the soundness of the calculated flows by comparison to previous
studies, regression equations, and APWA 5600 methods.
4.5.1 USGS Regression Equations
Estimates of flood-peak discharges for standard recurrence intervals are available from the U. S.
Geological Survey in the form of a set of published regression equations. These equations were used to
calibrate existing condition 100-year peak flows. Regression equations are derived from synthetic peak-
discharge data from calibrated rainfall-runoff model simulations using long-term rainfall and evaporation
data for 9 sites and observed peak-discharge data at 18 sites in urban areas and 10 sites in rural areas of
Missouri.
For the state of Missouri, USGS Fact Sheet 015-01, March, 2001 "The National Flood-Frequency
Program--Methods for Estimated Flood Magnitude and Frequency in Rural and Urban Areas in Missouri,
2000" was used to judge the accuracy of the hydrologic results obtained from XP-SWMM.
Stormwater Management Plan

Explanatory variables for rural and urban basins differ. For rural basins, the variables of interest are area
in square miles and channel slope. Variables for urban areas are the area of the basin in square miles and
the Basin Development Factor (BDF). The BDF is the sum of scores assigned to four different
characteristics of the basin that are related to urbanization: channel improvements, channel linings, storm
drains, and curb-and-gutter streets.
Owing to the nature of the process, and the limited types of data used in obtaining these estimates, the
possible error is quite large in the USGS estimates. The standard error produces an interval around the
computed value for any of these equations that will include about two thirds of the actual values that
might occur. The standard error for the different recurrence intervals ranges from 26% to 33% for urban
equations and between 31% and 43% for the rural equations.
Both rural and urban 100-year flows were examined in the analysis of this watershed for existing
conditions. An urban basin is one in which greater than 5 percent of the drainage area is subject to
commercial, industrial, or residential development. The analysis results are shown in Table 4-3.

All of the subsheds examined in this comparison were within the standard error of prediction.
4.5.2 APWA 5600 Rational Method
A further check was made in regards to small subshed areas, those areas of 200 acres or less. Twenty-
three subshed areas were selected and analyzed using the APWA 5600 rational method for calculating
peak flows. The Rational Method 10-year and 100-year peak flows were then compared to the XP-
SWMM 10 and 100-year flows. The results are listed in Table 4-4.
There are large individual variations, but the average differences are -2% for the 10-year flows and +25%
for the 100-year flows. The Rational Method does not route flows and only offers a linear solution to a
nonlinear problem, so variations are expected. These comparisons are useful in monitoring the SWMM

models. A large number of checks were made between the collected variables and the actual numbers in
the models, such as soil type, slope, land use, conduit statistics, etc., and these helped to verify the
accuracy of the model building methodology.
When the 100-year results are ordered by size it can be seen that the Rational Method tends to understate
runoff from smaller areas and overstate runoff from larger areas. This lends credibility to the SWMM
models developed for this study because this is an expected result from the Rational Method.

Although it is never desirable to proceed without gage data for calibration, it was done here, as it is
commonly done elsewhere due to the scarcity of gaged streams. Lacking this validation, the process of
checking different methods against one another is useful because it allows the model builder to
demonstrate that the model results are consistent with generally accepted practices in calculating these
statistics.

SECTION 5.0 - HYDRAULIC MODELLING
5.1 INTRODUCTION
The HEC-RAS program (Version 3.1.1) was used to calculate water surface profiles for steady, gradually
varied flow in natural and improved open channels. The model was also used to evaluate the effects of
various obstructions such as bridges, culverts, weirs and structures within the floodplain of the modeled
stream. HEC-RAS estimates water surface elevations in a river reach based on flows from the hydrologic
block (RUNOFF) of XP-SWMM. This section discusses the procedures used for the Moreau River South
project and guidelines developed during previous studies for developing HEC-RAS models. This section
describes in detail data development, model development, model-input parameters, data format, naming
conventions, and calibration.
The HEC-RAS model was developed to achieve the highest precision possible within limitations of the
study. Table 5-1 summarizes some of the watershed characteristics incorporated into the HEC-RAS
model.

5.2 DIGITAL TERRAIN MODEL
A digital terrain model (DTM) was developed from the mapping data provided by the City. The DTM’s
purpose for this study was to allow computer software to extract channel centerlines and cross section
data. Using HEC-GeoRAS, the information contained in the mapping was extracted from the DTM and
imported into the HEC-RAS model.
5.3 STREAM NETWORK
The stream network was derived from the hydrography information contained in the City data. In effect,
the stream network represents the channel centerlines of the streams modeled in HEC-RAS.
5.4 CROSS-SECTION CUT-LINES
Placement and alignment of cross sections were determined by engineering judgment. In general, cross
sections were placed closer together than the recommended maximum spacing of 500 feet.
Stormwater Management Plan
City of Jefferson, Missouri
19 March 4, 2005
Additional cross sections were added at bridges and culverts. As prescribed in the HEC-RAS Hydraulic
Reference Manual3, four cross sections are associated with each hydraulic structure as follows:
• Cross Section 1 is placed approximately 4 times the opening width downstream of the
structure.
• Cross Section 2 is placed at the downstream face of the structure, just outside of the roadway
embankment.
• Cross Section 3 is placed at the upstream face of the structure, just outside of the roadway
embankment.
• Cross Section 4 is placed approximately 1 times the width of the opening upstream of
structure.
Cross sections were delineated from left to right looking in the downstream direction and were drawn so
that each end projected beyond the maximum extent of the 500-year floodplain. Cross section stations
reflect the distance in feet from confluence.
5.5 MANNING’S “n” VALUES
Manning’s “n” values are empirical coefficients used to relate surface conditions to conveyance friction
losses in the HEC-RAS model. Table 5-3 below shows the relationship between land cover and
Manning’s “n” values. Typically, roughness coefficients used for this study were taken from the HEC-
RAS Reference Manual.

5.6 BRIDGES AND CULVERTS
For this study, 11 culverts were modeled in accordance with the recommended procedures outlined in the
HEC-RAS Hydraulic Reference Manual.
5.6.1 Cross Sections
Cross-sections 1 and 4 were located sufficiently upstream and downstream from the structure to represent
undisturbed flow in the channel. Cross-section 2 was located just downstream of the bridge face outside
of the roadway embankment. And finally, Cross-section 3 was located just upstream of the bridge face
beyond the limits of the roadway embankment.
5.6.2 Bridge Deck / Roadway
Bridge Deck/Roadway information was acquired from the topographic survey. Where survey data proved
to be insufficient, the data was supplemented with information from the base mapping.
5.6.3 Modelling Approach
Typically, the highest energy answer between Energy (Standard Step) and Momentum method was
selected for low flow calculations. For high flow calculations, the Pressure and/or Weir method was
used. As an exception, perched bridges and culverts were modeled using Energy methods. It should be
noted that this approach to bridge modelling was a general philosophy, but not a hard and fast rule. The
results from each bridge were evaluated, and engineering judgment was used to obtain reasonable results.
Stormwater Management Plan
City of Jefferson, Missouri
21 March 4, 2005
5.6.4 Internal Bridge Cross Sections
As general rule, internal bridge cross sections were not modified. However, some revisions to internal
cross sections may have been necessary. Specifically, when Cross Sections 2 and 3 were not cut
perpendicular to the bridge face, the deck / roadway would be obscured by the cross-sections. With weir
area (roadway) obscured, HEC-RAS uses the cross section points as the weir. As a result, the calculated
head on the weir is often overestimated. Where this conservatism was of particular concern, the internal
bridge cross section was modified so that the all of the roadway points were used for weir flow.
5.7 INEFFECTIVE FLOW AREAS
Ineffective flow areas were determined using cross-section plots, contour information and photos.
Ineffective flow area examples include:
• Floodplain areas significantly below the top of the channel bank not hydraulically
connected to the channel downstream
• Floodplain areas within hydraulic shadow of roadway encroachments caused by
contraction and expansion of flow through bridge or culvert openings
• Floodplain areas within hydraulic shadow of other obstructions or irregularities in the
stream valley floodplain
5.8 EXPANSION AND CONTRACTION COEFFICIENTS
Expansion and contraction coefficients were estimated based on the ratio of effective flow area in the
floodplain occurring at stream valley cross-sections, roadway crossings, and dams. Table 5-4 lists typical
coefficients used in the model. For roadway crossings, expansion and contraction coefficients were
applied to the first two cross-sections upstream and one cross-section downstream of the structure.

5.9 FLOW DATA
For this study, one-dimensional, steady state flows were used as a basis for hydraulic modelling. The
peak flow rates at points of interest in the watershed were estimated using the Runoff module described in
Section 4 of the report.
5.9.1 Profiles
Peak flow rates from the 2, 5, 10, 25, 50, and 100-year storms were used in the hydraulic analysis.
5.9.2 Flow Change Locations
At a minimum, HEC-RAS requires a flow rate to be established at the top of each reach. Theoretically,
flow rates increase continuously along a reach because of lateral inflow of runoff. While it would be
impossible to account for continuous increases in flow rate, it is appropriate to increase the flows at
particular cross section locations. These locations in the hydraulic model are reflective of hydrograph
calculations in the hydrologic model.
5.9.3 Boundary Conditions
Since all of the streams modeled, Moreau River South and its tributaries, are controlled by the
stream/river they discharge to, boundary conditions were set with a known water surface elevation at each
junction if known otherwise they were set to normal flow conditions.
5.9.4 Flow Conditions
Floodplain information was calculated for two types of land uses: existing conditions and future surface
conditions.
5.9.5 Detention / Storage
Because HEC-RAS is a steady state model, it cannot inherently model attenuation created by ponds,
lakes, and some highway embankments. Attenuated flow locations were modeled in XP-SWMM, and the
results were incorporated into HEC-RAS.
5.10 FLOODWAY ANALYSIS
Floodway limits were not determined as part of this study.
5.11 CALIBRATION
Due to the lack of any physical data (such as gage records) indicating high water elevations for a known
flow recurrence interval, true calibration (as defined in the scientific community) could not be performed.
Therefore, a comparative analysis was completed using several available sources of information.
Stormwater Management Plan
City of Jefferson, Missouri
23 March 4, 2005
5.11.1 Previous Studies
Several previous hydrologic and hydraulic studies have been performed in and around the City of
Jefferson including the FEMA FIS for Cole County and the City of Jefferson. These studies were
reviewed and pertinent information used.
5.11.2 Stormwater Questionnaire
The stormwater questionnaire distributed for a previous phase of this study proved to be helpful as well.
Using GIS, the results of the questionnaires could be plotted on the mapping with the preliminary
floodplain. Results of the model generally corroborated the problem areas revealed by the questionnaire.
Clusters of reported flooding indicated major areas of concern caused by obstructions or undersized
channels. Scattered areas of reported flooding were more indicative of localized problems such as
downspouts and clogged drainage systems.
5.11.3 Previous Complaint Files
The City’s file of previous complaints was obtained and, to the extent possible, these locations were
added to the GIS database.
5.12 QUALITY CONTROL / DEBUGGING
Once the HEC-RAS models were calibrated, a final examination of the input parameters was made using
the Check-RAS program distributed by FEMA (Version 1.1).
According to the documentation accompanying the program: Check-RAS is a program designed to check
the reasonableness of the data found in HEC-RAS. Geometric, steady flow, and output data are three
types of data used to verify that hydraulic estimates and assumptions made in the model appear to be
justified and are in accordance with the assumptions and limitations of the HEC-RAS program and
applicable FEMA requirements.
Check-RAS allows users to examine a variety of parameters from HEC-RAS data files, as well as
generate, view, and print reports, which include tables and messages. Using the HELP message database
can reference additional information about the messages identified.
Although the HEC-RAS program provides several messages, CHECK-RAS differs from HEC-RAS in
several ways. Only, CHECK-RAS does the following:
• Categorizes floodplain modelling into five distinct areas of checks
• Provides a summary table and messages for each area of check
• Assesses the suitability of roughness coefficients and transition loss coefficients
• Assesses the suitability of starting water-surface elevations
• Assesses bridgs and culvers modelling
Stormwater Management Plan
City of Jefferson, Missouri
24 March 4, 2005
• Provides a detailed floodway analysis
• Compares important parameters among multiple profiles
• Proposes solutions through the use of the Help screens
Each Check-RAS warning was reviewed and evaluated for applicability. Necessary changes were made
to the HEC-RAS model.

6.1 Moreau River South
6.1.1 Basin Description
Moreau River South watershed (see Exhibit 1) is comprised of those areas within the existing corporate
limits and potential future area of annexation lying north of State Highway C and new State Highway
179. The main stem of the Moreau River is specifically excluded from the scope of this report.
The watershed’s land use is currently dominated by undeveloped areas. Agriculture, meadow/pasture,
brush and wooded areas amount to over 55 percent of the land use. Medium density residential
dominates the remaining area with scattered zones of low density residential, commercial and industrial
land use. The existing conditions land use breakdown is provided in Table 6-1 and is shown in Exhibit
4.
Future surface conditions were projected to have nearly double the medium density residential, three
times as much commercial and nearly twice the industrial area as existing conditions. The undeveloped
areas will have fully developed or been utilized for parks and open space. The future surface condition
breakdown is provided in Table 6-1 and is shown in Exhibit 5.

6.1.3 Existing Drainage System
Less than half of the Moreau South watershed is located inside the municipal boundaries of the City of
Jefferson, however detailed study of the stormwater system extended into regions of Cole County that
were identified as possible areas of annexation. Within the detailed study area there are 11 hydraulic
structures modeled in HEC-RAS and 207 'links' (culverts or pipe runs) modeled in XP-SWMM. These
links comprise about 5.1 miles of stormwater conduits 24 inches and larger. The link names do not
correspond exactly with the surveyed conduit names because of modelling constraints, therefore the GIS
Stormwater Management Plan

and XP-SWMM files furnished to the City and County must sometimes be used to find the locations and
statistics associated with each.
6.2 EVALUATION CRITERIA
The design criteria for system performance currently observed by the City of Jefferson is based on land
use or zoning. These criteria have been taken from the Storm Drainage Design Manual4 and are as
follows:

For various reasons these design criteria cannot be the sole criteria for evaluating the system. Much of
this study examines older elements of the stormwater conveyance system as well as portions of it that are
outside the City limits and were not subject to City regulation when built. In addition, these are design
criteria, meant to be applied to new construction. Hence evaluating the performance of the system is
more complicated than simply flagging elements that do not pass the runoff from the applicable event.
6.3 DRAINAGE SYSTEM PERFORMANCE
The drainage system was evaluated as two separate parts: enclosed system and open channels. An
enclosed system was defined as multiple, connected pipes. As such, all of the elements considered as
enclosed systems were in the upper reaches of the watersheds and were modeled in XP-SWMM. These
enclosed systems then discharged into open channels and were modeled in HEC-RAS. This combination

of modelling techniques was used because XP-SWMM models enclosed systems better than HEC-RAS,
and HEC-RAS better represents extended open channel systems.
6.3.1 Major Structure Modelling Results from HEC-RAS
Table 6-5 summarizes the major structures analyzed in the Moreau River South Watershed with HEC-
RAS. The table provides a brief description of the structure, its length and a listing of the hydrologic
conditions examined. “Existing” indicates the flow at each structure with the current ground cover and
land uses observed in the watershed. “Future” is the future flow predicted to occur as the watershed
develops. The table also provides an indication of whether modelling predicts overtopping of the
structure for three key runoff events. These structures can be located in Exhibit 1 and the results can be
examined more closely in the HEC-RAS model digital files furnished with this report.
The City's design criteria requires that structures in residential streets convey a 10-year event without
overtopping. Bridges and culverts on commercial streets must convey a 25-year event without
overtopping. Overtopping depths in excess of design criteria are shown in gray cells in the table.

The analysis suggests that the following structures lack sufficient capacity to current design standards:
• MR-002 on a tributary to the Moreau River 2,350 feet south from the end of Green Meadow
Drive.
• MR-003 on Hoffman Drive approximately 350 feet east of Tanner Bridge Road.
• MR-016 under Weathered Rock Road 330 feet west of State Highway B.
• MR-042 under Amanda Dr. 150 feet south of Brooks Dr.
The analysis also indicates that the following structure may become inadequate as the watershed becomes
urbanized:
• MR-001 on Green Meadow Drive approximately 1,000 feet south of Payne Drive.
6.3.2 Minor Structures - Depth of Overtopping
The performance of the pipes that make up the minor system are reported in Appendix B and in the GIS
and XP-SWMM files furnished digitally with this report. In Appendix B the peak flow routed through
each pipe is reported with the calculated design flow of that pipe and the occurrence and depth of
overtopping. The locations of these pipes are shown in Exhibit 7.
The depth of overtopping was determined by modelling an aboveground channel above each pipe so that
runoff was allowed to travel downstream when pipe capacities were exceeded. Four types of overland
channels were modeled: street and gutter flow; flow over a sag in the road above a culvert; flow between
houses through a side yard swale; and the flow through backyard swales. The overtopping elevation, the
slope, and the sides of each of these trapezoidal channels was estimated for each different type and
location. Due to the accuracy and resolution of elevations and topographic data these overland channels
and depths only approximate actual conditions, but are still useful measures of performance.
Table 6-6 below summarizes the performance of the 207 links, or pipes, analyzed in the Moreau South
study area.

Number of links that fail to pass the

It can be seen that 31% of the links fail to pass the existing 10-year flow, and with the future scenario
37% will not pass the future flow without overtopping. It should be noted that overtopping in the model
does not always mean overtopping in the actual system. Nor does it mean that the design was flawed, or
that there is necessarily a problem at this location. The model does not take into account all of the factors
that affect system capacity, and these other factors must be considered when analyzing the system. The
recommendations to be made in the next phase of this study will factor in field investigations by the
Engineer, complaints, staff feedback, special conditions, and the age and condition of the system.

from surface runoff and discharge it at a controlled rate less than the peak inflow rate.
Development - Any activity that alters the surface of the land that generally creates additional
impervious surfaces including, but not limited to, pavement, buildings and structures.
Drainage - Interception, collection and removal of excess stormwater from an area into another area
or into a receiving water body.
Enclosed Drainage System - A drainage system consisting of essentially continuous pipes and/or
box culverts below the ground surface.
Erosion - The removal of soil particles by the action of flowing water.
Excess Runoff - Direct surface runoff that cannot be accommodated satisfactorily by the existing or
planned drainage system.
Flood Control - Preventing the entry of stormwater into an area from another area, or from a stream

32 March 4, 2005
Floodway - A tool or concept used by local communities for flood plan management. The area of
the 100-year flood plain is divided into a floodway and floodway fringe. The floodway is the
channel of the stream plus any adjacent flood plain areas that must be kept free of encroachment
to that the 100-year flood can be carried without substantial increases in flood height. Minimum
Federal standards limit such increases to 1.0 foot, provided hazardous velocities are not exceeded.
Freeboard - The vertical difference in elevation between the hydraulic gradient and a referenced
point. Examples are the difference between the maximum water surface level behind a dam and
the top of a dam, or the difference in elevation between the water surface at a culvert beneath the
roadway and the surface of the roadway.
Head - The difference in depth of a liquid at two given points; a depth generally expressed in feet.
HEC-RAS - United States Corps of Engineers Hydrologic Engineering Center’s program for
modelling water surface profiles in open channels, River Analysis System.
Hydraulic Gradient - The elevation of the surface of the water in the drainage system at any point.
Hydrograph - A graph of runoff rate, inflow rate or discharge rate, versus time.
Hydrologic Soil groups - A soil characteristic classification system defined by the U.S. Soil
Conservation Service in which a soil may be categorized into one of four soil groups (A, B, C, or
D) based upon infiltration rate and other properties.
Impervious Surface - Any surface that does not readily permit water to infiltrate. Examples are
roofs and concrete or asphalt-paved surfaces.

Improved Channel - Any channel whose characteristics are changed by either grading or
construction of lining materials.
Interception - Rainfall that is caught by foliage, branches, leaves, and other aboveground objects.
Lag - The time interval from the center of mass of excess rainfall to the peak rate of runoff.
Level of Service - The return period for which a drainage system, or an individual element of that
system, has adequate hydraulic capacity.
Master Planning - A “systems” approach to the planning of facilities, programs and management
organizations for comprehensive control and use of stormwater within a defined geographical
area.
Natural Channel - An existing channel that has not been appreciably altered by grading, lining or
changing its course.

comparatively short lengths enclosed by pipes or culverts.
Pervious Surfaces - Surfaces that absorb water such as undeveloped areas, fields, yards and other
unpaved areas.
Reach - A specific length of the storm drainage system between two points. For example, a reach
may consist of a single culvert or may consist of several connected pipes or channel sections.
The term "line" may also be used synonymously within the report.
Receiving Waters - Streams, lakes, bays, etc., into which stormwaters are discharged.
Return Period - A statistical term for the average frequency that a given event may be expected to
occur, although it does not imply that the event will occur regularly at even intervals. It can also
be defined as the reciprocal of the probability of an event. For example, a storm having a 10-year
return period statistically can be expected to occur once in a period of 10 years, a probability of
occurrence of 0.10, or 10%. However, the event may occur at any time, and two such events may
actually occur on successive days.
Sediment - Soil particles eroded by flowing water; either in suspension in that water or as deposited.
Storm Drainage System - Natural or constructed facilities and appurtenances, such as ditches,
natural channels, pipes, culverts, bridges, improved channels, street gutters, inlets and detention
facilities, which serve to collect and convey surface drainage.
Storm Sewers - Usually, enclosed conduits that transport excess stormwater runoff toward points of
discharge (sometimes call “storm drains”).
Stormwater Management - Encompasses both “control” and “developmental” activities in which
there is physical interaction with stormwater (a broader interpretation includes activities of an
institutional nature – financing, staffing, etc.).

Stormwater Storage - Temporary storage of excess runoff on, below, or above the surface of the
earth for the purpose of attenuating excess runoff.
Time Of Concentration - The time period necessary for surface runoff to reach the outlet of a sub-
basin from the hydraulically most remote point in the tributary drainage area.
Travel Time - The sum of the time intervals for overland flow, sewer or gutter flow, and pipe and
channel flow from the hydraulically most remote point in the tributary to the discharge point of
interest.

synonymously with the terms tributary area, drainage area, drainage basin, catchment area,
subwatershed and subarea.
Water Surface Profile (Existing) - the “Existing” water surface profiles represent flooding
conditions based on current land use conditions within the study area.
Water Surface Profile (Future) - the “Future” water surface profiles represent flooding conditions
based on future land use conditions within the study area.
