PROPOSAL
BALDWIN DRAINAGE BASIN FLOOD IMPROVEMENTS
CITY OF OSHKOSH, WISCONSIN
FEBRUARY 7, 2007
EARTH TECH'S RESPONSIBILITIES
A. DESCRIPTION OF PROJECT .
Earth Tech's services will include engineering services required to perform a comprehensive
analysis and design of a stormwater detention basin, storm sewers, and an analysis of the
stormwater system capabilities within the Baldwin drainage basin. The Baldwin basin is 38 acres
in size.
B. SCOPE
Services to be provided for the Project are as follows:
Data Collection and Survey
1. Collect and review existing plans, studies, property information, and correspondence
related to the project area.
2. Conduct a field survey of the project area including one foot contours, existing utilities,
property lines, existing easements, and right-of-way lines along New York Avenue from
Jefferson Street to Broad Street and for the pond location from New York to Baldwin.
Field survey will also include locating existing manholes and inlets on sanitary and storm
sewers and measure downs on the following streets:
. Harrison from New York to North of Tennessee
. Jefferson from New York to Tennessee
. Mount Vernon from New York to Custer
. Eastman from New York to Custer
. Grand from New York to Custer
. Broad from New York to Tennessee
. Tennessee from Harrison to Broad
. New York from Harrison to Jefferson
Drainage Basin Modeling and Analysis
3. Hydrologic - Hydraulic Analysis
A hydrologic-hydraulic (H&H) analysis of the Baldwin Basin storm sewer system will be
conducted by Earth Tech. This analysis will include the public storm sewers in the
following streets. This analysis will utilize the survey information gathered in the
preceding task.

Analyzed Storm Sewers
Within Street Right of Way Between These Streets
Harrison Street E. New York Avenue and E. Custer Avenue
Jefferson Street Baldwin Avenue and Tennessee Street
Mount Vernon Street E. New York Avenue and E. Custer Avenue
Eastman Street E. New York Avenue and E. Custer Avenue
Grand Street E. New York Avenue and E. Custer Avenue
Broad Street E. New York Avenue and Tennessee Street
E. Tennessee Street Harrison Street and Broad Street
E. New York Avenue Harrison Street and Grand Street
The hydrologic-hydraulic (H&H) analysis conducted by Earth Tech will serve several
purposes:
. Verify or modify previous analyses conducted within the drainage basin
. Predict existing storm sewer flow capacity under selected rain conditions
. Identify locations and severity of surcharging and/or surface flow of stormwater
. Predict storage volume requirements of detention facilities to meet project goals
. Provide design information for inlet, and outlet structures of management
structures
Earth Tech will use the XP-SWMM™software to conduct the H&H analysis. XP-SWMMTM
allows for efficient and accurate velocity, water surface elevation, flow, and volume
calculations under a variety of climatic and hydrologic conditions. The software also
accounts for closed system (pipe) flow - both pressurized and non-pressurized
conditions - open channel flow, and culvert flow all within a single drainage system.
Additionally, the model will account for the backwater effects of Lake Winnebago. Finally,
the model will evaluate alternative management measures to help identify the optimal
approach(s) to meet the city's stormwater management goals.
The following steps will be conducted under this task:
a. Assemble drainaQe basin data:
. soils, (from NRCS and city's local observations)
. land use, (City's GIS system)
. stormwater conveyance system data, (existing city data and field survey
results)
. rainfall (TP 40 or Huff-Angel Bulletin 71)
. topographic (existing contour maps and field survey results)
b. Verify/modify drainaae basin and sub-basin delineations: Earth Tech will confirm
the Baldwin Basin drainage area and the sub-basin areas contributing surface
runoff to key locations, including the detention facility. This process will include
windshield observations of drainage divides, and confirmation by city staff
observations. The basin and sub-basin delineations will be prepared in a CAD
and or GIS format.

A r"",lill""oliona;Ud. Compa1lY
c. Prepare hvdroloqic model input files: Earth Tech will construct model input files
representing the hydrologic conditions of each sub-basin delineated under Task b
above. Earth Tech will use "curve number" methodology for the hydrologic
calculations. Establishing flow paths, time of concentrations, weighted curve
numbers, and other factors will be done for each sub-basin and the resulting
hydrographs are input to the hydraulic component of the model.
Rainfall files are also added at this stage. The model will be run for the 2-year,
1 O:'year and 25-year rainfall depths, The event durations will be selected based
on state and local ordinance requirements, and overland flow travel times
calculated for the project area.
d. Construct system model: conveyance system links and nodes: During this step,
Earth Tech assembles the data describing the conveyance system: pipes,
channels, culverts, bridge openings, natural detention, constructed detention, and
sub-basin confluences. These components drive the timing and discharge rates
through the system.
e. Run XP-SWM~M. check for continuity. and QC model: Upon completion of the
model construction, a series of checks and QC reviews are conducted. The
model must show that the system does not gain or lose runoff volume during the
event simulations.
f. Verify the model: Upon completion of the internal QC process, the model results
will be reviewed by city staff. The model results may show portions of the system
where capacity deficiencies result in surface flooding. These results will be
verified through experience and observations of city staff to make sure the model
results are indicative of actual conditions.
g. Configuring the Storm Sewer and Detention Pond System: Under this task Earth
Tech will use the verified XP-SWM~M model to configure proposed storm sewers
to convey the 1 O-year storm event in the project area as described in the
preceding "Analyzed Storm Sewers" table. Potential conflicts with utilities and
lack of street cover will be considered in this configuration. In addition, the model
will be used to determine the proposed detention pond configuration.
h. Provide desion information: The model will be used to provide key design
information for the recommended structural measures. This will include proposed
storm sewer diameters, lengths, full flow pipe capacity, and invert elevations.
This information will be provided in a tabular format suitable for use by a design
engineer to design the proposed system. In addition, detention pond design
parameters such as outlet structure design (pipe size and slopes, outlet structure
elevations, weir configurations), flow velocities for erosion control needs, and
detention basin storage volumes will be provided for the design phase of this
project. Model results of the peak flow release rates both with and without the
proposed improvements will be reported. Proposed inlet locations will be
determined using standard design practices and will be conveyed to the client in a
graphical format.

purposes, ETI will assist the Client in selecting a geotechnical firm to make the
subsurface explorations and prepare a geotechnical report. The contract for
geotechnical work shall be between the Client and the geotechnical firm and the costs
shall be paid by the Client.
