SUBJECT: Dubuque Levee and Floodwall Certification — PAL Progress Report #4
DATE: November 8, 2010
INTRODUCTION
This memorandum transmits the PAL Progress Report #4 to FEMA for certification of
the Dubuque levee and floodwall system along the Mississippi River. This progress
report is a bi- monthly update that FEMA requested as part of the City of Dubuque's
Provisionally Accredited Levee (PAL) Agreement.
DISCUSSION
The City of Dubuque must certify the levee system complies with federal regulations
concerning provision of 100 -year flood protection for the community. This certification
must be submitted before May 17, 2011 and be signed by a professional engineer. We
plan to have a member of the City's Engineering Department provide this certification.
City staff has reviewed the June 2010 Engineering Technical Review Report prepared
by the U.S. Army Corps of Engineers (USACE) on the Dubuque Levee System. Overall,
our levee system appears to meet or exceed most standards according to the report.
The City Council officially adopted the July 2002 Operation and Maintenance Manual for
the Dubuque levee and floodwall system on May 3, 2010 for submittal to FEMA.
Subsequently, the June 2010 USACE report recommended that the City update the
Operation and Maintenance Manual and the Emergency Flood Control Plan to ensure
that information in both plans was clear, consistent, and coordinated with respect to
operation, maintenance and emergency flood control response. City staff completed a
simultaneous review of both plans in October 2010. Enclosed are the revised Operation
and Maintenance Manual and the revised Emergency Flood Control Plan that will be
provided to FEMA as part of the bi- monthly PAL Progress Report. The remaining
sections and all Appendices of the Operation and Maintenance Manual sent to FEMA in
May 2010 are unchanged.
The USACE report identified two main areas that require further analysis for the
Dubuque levee and floodwall system. One area is for interior drainage analysis. The
City retained CDM to do as it is an extension of the work the firm is doing for the FEMA
flood map technical appeal. The analysis is to be completed by December 15, 2010.
Dubuque Levee and Floodwall Certification — PAL Progress Report Page 2
The other area is for structural analysis of the levee and floodwall system to evaluate
levee embankment stability. The City Council authorized issuance of an RFP for this
work, and then selected GEI as the consultant on September 20, 2010. GEI conducted
a site visit on October 20, 2010 to begin their analysis. The analysis is to be completed
by December 15, 2010.
REQUESTED ACTION
The requested action is for the City Council to officially adopt the revised sections of the
Operation and Maintenance Manual and the revised Emergency Flood Control Plan,
both dated October 2010, and then to direct staff to transmit PAL Progress Report #4
and these two documents to FEMA.

Masterpiece on the Mississippi
City of Dubuque
FOREWORD
Construction of the flood protection project for the City of Dubuque, Iowa, has been
completed, and the city has accepted transfer and responsibility therefore. This manual
has been prepared to assist the city in complying with the regulations for operation and
maintenance as prescribed by the Secretary of the Army in conformance with Section 3
of the 1936 Flood Control Act, as amended.
The manual contains a copy of the approved regulations, information on procedures
during flood periods, a copy of the assurance of cooperation furnished by the city, and a
copy of the report form to be furnished by the city at regular intervals concerning
inspection, operation, and maintenance.
As -built drawings of the structures, shop drawings, a list of renewal parts, pump
characteristics curves, and instructions and special tools required for installation,
inspection, and maintenance of pumps and motors have been furnished the city.
DUBUQUE, IOWA
MANUAL FOR OPERATION AND MAINTENANCE
OF LOCAL FLOOD PROTECTION WORKS
I- GENERAL
1. Authorization. The Federal project for local flood protection at Dubuque, Iowa, was authorized by
Public Law 87 -874, to be constructed substantially in accordance with recommendations of the
Chief of Engineers in House Document 450, 87th Congress, 2d session. Repairs made following
the 2001 flood are authorized under PL 84 -99.
2. Local cooperation. The authorizing legislation for the project requires that the city of
Dubuque give assurances satisfactory to the Secretary of the Army that it will:
a. Provide without cost to the United States all lands, easements, and
rights -of -way necessary for the construction of the project;
b. Hold and save the United States free from damages due to the construction
works;
c. Maintain and operate all the works after completion in accordance with
regulations prescribed by the Secretary of the Army;
d. Modify or relocate buildings, utilities, sewers, and other facilities where
necessary in the construction of the project, including necessary widening of levees to
provide for roadways; and
e. Obtain legal control over pondage areas and prevent encroachment until
substitute areas or increased pumping capacity have been provided.
A local cooperation agreement for the 2001 PL 99 repairs was signed on September 6,
2001. A copy of agreement furnished by the city is included in this manual as Appendix B.
3. Description. The project consists of levees and floodwalls giving protection against a
Mississippi River flood, which would have a 0.5 percent chance of occurring per year.
Included are ponding areas for temporary storage of rainfall runoff, gravity outlets for
discharge into the river at low stages, and pumping plants for use when gravity drainage is not
possible. Gatewells are provided in drains and sewers that pass through the levees and walls. To
reduce the number of drains passing through the protective structures, some drains have been
connected to interceptor sewers, which discharge through the gated structures. Where the levees and
walls cross streets or roads that are necessary to be retained for access, gated closure structures
through or ramps over the protective structures are provided.
The repairs made following the 2001 flood included riprap replacement in several locations.
Riprap was lost or dislodged during the high water event.
4. Ice Harbor Closure. A closure has been provided across the entrance to the commercial harbor,
known also as the Ice Harbor. It consists of two sections of hydraulic sand fill and I -walls between
which is a steel miter gate with concrete abutments and miter sill. This structure is founded on wood
piling; it contains a pumping plant. During high river stages, the gate will be closed and the harbor will
act as a ponding area, which will be kept at a nondamaging level by pumping.
5. General Plan. The general plan of the project and cross sections of the levees,
floodwalls, and harbor closure structure are shown on the as -built drawings, previously
furnished.
6. Joint Inspection. The Corps of Engineers Clinton Flood Area Engineer or his
authorized representative and the city's superintendent shall make an annual joint inspection of the
project. The Flood Area Engineer will initiate these inspections and will coordinate with the city's
superintendent on acceptable inspection dates. See Section appendix E for listing of points -of-
contact, addresses, and telephone numbers.
Inspection Schedule. The following annual schedule is recommended.
Date Action
October /November Corps of Engineers conducts joint inspection with the
project superintendent.
December Corps of Engineers forwards a report to the city with
the inspection results.
April thru June Independent inspection and corrective actions are
undertaken by the city.
July Report submitted by the city to the Corps of Engineers outlining
actions undertaken to correct deficiencies noted in Corps'
inspection report.
Periodic Inspection. Periodic inspections shall be made by the city's project
superintendent as specified below:
a. At intervals not exceeding six (6) months.
b. After a high water event or at such times deemed necessary by the
project superintendent.
7. Change in superintendence. In the event of a change of superintendence for operating and
maintaining the project, the name, address, and telephone number of the new Superintendent should
be furnished the District Engineer.
II - ORDINARY INSPECTIONS, TESTS AND OPERATIONS
8. General regulations. Ordinary maintenance of the project works shall follow an
established schedule of maintenance work for each six -month period and shall include
maintenance work found necessary in periodic inspections. A copy of the general
regulations for maintenance and operation approved by the Secretary of the Army in
accordance with authority contained in Section 3 of the 1936 Flood Control Act, Public
Law No. 738, Seventy -fourth Congress, as amended and supplemented, is made part of this manual
as Appendix B. Instructions in these regulations will serve as a guide for ordinary inspections, tests,
and operations to insure the effectiveness of the project. As least once each year trial runs should be
made on closure structures, gates, and each year trial runs should be made on closure structures,
gates, and pumping stations for assurance that these features are operable when needed. Applicable
paragraphs covering the project features are:
Levees 208.10(b)(1)
Floodwalls 208.10(c)(1)
Drainage structures 208.10(d)(1)
Closure structures 208.10(e)(1)
Pumping plants 208.10(f) (1)
Miscellaneous facilities 208.10(h)(1)
9. Project Responsibilities. It is imperative that the Superintendent and other city officials charged with
project responsibilities recognize that the city should be self- sufficient in flood emergencies. This
requires the city to maintain an adequate stock of equipment, supplies, and materials, which may not
always be available from general sources in the city.
At least twice each year responsible officials should make a careful review of the supply of items
needed and of the general plan to be followed in an emergency. As a minimum
requirement, the following shall be available:
a. Convenient and dependable sources for riprap and embankment materials and
the equipment necessary to deliver these materials to any point on the project.
b. An ample supply of sandbags and sand for use at locations which require
emergency sandbagging during a flood.
c. A readily available source of polyethylene, 4 to 6 mils in thickness, for use in
emergency sandbagging and in assuring watertight conditions at closure structures.
10. Preparations of pumping stations. The four pumping stations are located in the line of protection
at Hawthorne Street, at Bee Branch, in the south abutment of the harbor closure, and at Maus Park.
Paragraph 208.10(f)(I) of the Flood Control Regulations specifies detailed requirements for periodic
inspection and trial operation of all operating equipment in the pumping stations to insure availability
of the stations for instant use. Detailed procedures for preparatory work and trial operations to assure
proper performance of the pumping equipment during flood periods follow.
d. Preparatory operations.
(1) Motors. Check oil level indicators and fill to proper height as necessary.
(2) Pumps. Fill lubricators with grease and operate in accordance with
instructions on the front of the lubrication reservoir.
e. Trial operations.
(1) Rotate each pump shaft by hand to ascertain that the shaft and impeller
are not binding. The hand - off - automatic selector switch should be in "Off' position for this test.
(2) Check the main circuit breaker to see that it is in the "On" position.
(3) Turn the hand - off - automatic selector switch to "Hand" position. With
the selector switch in the position, each pump can be operated independently of the float switch by
using the stop and start buttons on the motor control panel.
(4) Check motor frames for warmth to determine if motor heaters are
operating. The heaters are turned off automatically when the motor is running.
(5) Start and stop each pump by pushing the respective start and stop
buttons located on the motor control panel. Don not run the pumps in- the -dry condition
for prolonged periods of time as serious damage can result. Pumps may operate up t� 2
minutes in- the -dry in accordance with the manufacturer's recommendations providing
they are properly lubricated with oil and grease. It is necessary to test -run the pumps
once a month to keep the shafts and bearings smooth and rust -free. These monthly test -runs must be
no longer than time interval stated if the pumps are operated in- the -dry condition, that is, with no
water in the sump. Before each monthly test -run is performed, the pumps and motor must be properly
lubricated in accordance with the instructions in the lubrication reservoir.
(6) Check motor and pump performance for undue noise, vibration, or
overheating.
(7) Rotate the float control pulley by hand to ascertain that the float is free to
travel in the float guide tube.
(8) Return the hand - off - automatic selector switch to the automatic position.
This will put the storm pumps in automatic operation under control of the float switch.
(9) Draw the stormwater pump circuit breakers out to the test position. In
this position, the controls are operable, but the breaker is not connected to the power source or to the
pump motors.
(10) With the stormwater pump circuit breakers in the test position; check
the settings of the float control switch by rotating the float control pulley by hand to
simulate the pump chamber operating elevations shown for each station. Due to delay
relays in the starting circuits, the pump circuit breakers will not close immediately when the desired
elevation is reached, so it will be necessary to pause until the corresponding pump circuit breaker
closes before turning the float pulley to the next higher elevation. Adjust float control switch settings
as required.
f. Upon completion of the above test, the controls shall be set as follows:
(1) Main circuit breaker in "On" position.
(2) Stormwater pump selector in "Off position.
III - MAINTENANCE AND OPERATION
11. Protective works. The levees provide for a very high degree of protection. It should
be realized, however, that these structures are vulnerable in a number of ways, especially during high
river stages. Overtopping of a levee during a flood equal to the design flood could occur by
degradation of the levee from excessive erosion by wave wash. Current scour and seepage through
the levees or under them also threaten their stability. Wave wash or current scour could conceivably
occur even at lower stages. To be prepared to cope with such occurrences, personnel charged with
responsibility for maintenance and operation should become familiar with the general regulations in
Appendix B. Supplementing these regulations are detailed instructions of flood fighting, with
illustrations and typical photograph, included as Appendix C.
12. Periodic patrols. Periodic patrols of the levees and floodwalls should be made by
responsible personnel for assurance that these structures are not being encroached upon, that the
levees are not being degraded, and that undesirable growth of vegetation is not taking place on or
near the structures.
13. Continuous Patrols. When the river reaches a stage of 24 feet, continuous patrolling of the levees
and floodwalls should begin. The locations of potential danger zones should be ascertained to permit
prompt action and correction of any condition, which endangers the integrity of the levee or stability of
the floodwalls.
It should be noted that stages mentioned in this manual are based on the Dubuque gage with zero
elevations 585.5.
14. Gatewells. Following is a list of fourteen gatewells in the project, the size of gates, and the rising
river stage indicating that the gates should be closed. The locations by stationing may be determined
from the as -build drawings of the project furnished the city.
The following table replaces that in the original O &M manual.

Note 1. This is a butterfly valve located in the power company's seal well
and is to be closed when the gate at station 92 +77 is closed. The power
company's condenser system pumps will provide the head necessary to
discharge the cooling water over the levee through the emergency discharge
line.
Note 2. Personnel from the power company will regulate the intake water by
opening and closing the gate as required. The gate should be closed if a
rupture occurs in the flume landward of the gatewell.
Note 3. Not applicable.
Note A. The Roosevelt Storm Sewer is a pressure gravity line due to its high elevation
inverts. This gate is to be left open unless a break occurs in the Roosvelt Street Sewer. Water will
back into the water intakes on Kerper Blvd. when the river stage reaches 25 feet. Flap gates are
installed in each water intake. In case of a break in the storm sewer line the gate on this 84" sewer
can be closed at the levee. Once the gate is closed, a pump would need to be installed at the
Kerper intakes for storm water control during rain events.
Note B. This gate is no longer to be regulated. This section of I -wall has been covered with earthen
fill. The gate will be left in the closed position at all times. The gate can be returned to service in the
future if ever necessary.
Note C. This gatewell closure is revised to 16.0 in lieu of 12.5 in the
original O &M manual.
Note D. This gatewell was taken out of service. The 30" pipe no longer
routes through the levee.
The gate - closing operations must be completed by the time rising river levels reach the
stage indicated above. The City Engineer or the Superintendent should evaluate the daily rise of the
river and the time and manpower needed to close the gates at each of the stages indicated above.
The following paragraph provides information on gate- operating procedures and operating time for
opening and closing the gates.
15. Sluice gate operation. The sluice gates and pedestal lifts for the interior drainage
system and pumping stations were supplied by ARMCO. All gates, except for those on the cooling
water emergency discharge line, station 68 +49, and the sanitary pressure sewer, station 181 +00,
have hand -wheel lifts. The latter have butterfly valves rather than sluice gates, and have manually
operated hand -wheel flood stands. The cable and drum operation of the sluice gates in the Bee
Branch pumping station have been retained from a precedent local project. The following information
on the pedestal lifts covers the operations characteristics of the models on the project.

earthen fill.
The gates should be inspected each spring to insure that the rubber seals are not worn, that the
hinges are not binding, and that all the necessary hardware is available. The gates should be closed
and bolted in place, and the seals should be inspected for watertightness and flexibility at this time.
17. Harbor closure. The harbor closure is located across the entrance to a commercial
harbor, known also as the Ice Harbor. It consists of a structural steel miter gate with
concrete abutments and a miter sill, located between two sections of hydraulic sandfill and I- walls.
This structure is founded on wood piling. It contains gate- operating machinery and a pumping plant
with two units, each rated 7600 gpm with 28 total dynamic head. During high river stages, the gate
will be closed and the harbor will act as a ponding area, kept at a non - damaging level by pumping.
The circuit breakers for the entire structure are located in the pumping station in the south abutment.
They must be closed to activate the equipment being tested.
a. Preparatory operations - miter gate.
(1) Gate operating machinery. Check oil cups and grease fittings; fill with
lubricants recommended by manufacturer. Grease sheave base under sweep of gate
operating beam.
(2) Miter gate. Check grease fittings; fill with lubricants recommended by
manufacturer. Check pintle grease pipes for ruptures and evidence of escaping lubricant. Such
rupture and lubricating failure may ultimately cause binding of the pintle bearing and prevent closing
the gate.
(3) Periodic tests. Intervals not to exceed 90 days. From the control panel
on top of the south abutment the leaves may then be swung to partial or complete closure as desired.
Bring leaves to recessed position and deactivate station. Open circuit breaker inside pump station.
b. Flood conditions - miter gate. To decrease the length of interruption of passage through the
structure, there may be a tendency to postpone closing of the gate and initiating of ponding potential
until a river stage of 16 feet or even 20 feet is reached. As the flow into the harbor from a heavy,
prolonged rainstorm greatly exceeds the capacity of the pumps, the following rules are recommended
for guidance:
Do not close gate.
(1) River stage 16 feet
(a) Local heavy showers, river stage forecast 17 feet:
(b) Local heavy showers, river stage forecast over 18 feet:
Close gate, pump harbor down to 10 -foot stage.
(c) No precipitation, river stage forecast over 18 feet:
Close gate, pump harbor down to 10 -foot stage.
(2) River stage 17 feet
(a) River stage forecast over 18 feet:
Close gate, pump harbor down to 10 -foot stage.
The stage - equalizing gate located on the river face of the north abutment must be closed to prepare
the harbor for pondage.
c. Recessing the miter gate. After a flood peak, the river may recede to, and for
some time even fluctuate about, some intermediate level lower than the 18 -foot flood stage while the
harbor is still at some discretionary lower stage based on local experience and evaluation of
precipitation forecast. As the gate cannot be operated under unbalanced pressure, the stage -
equalizing gate located on the river face of the north abutment must be opened some three days
before a non - damaging river stage is anticipated. After stage equalization, the gate may then be
recessed and the station closed down by reversing the order of steps taken to close the gate.
18. Sandbag closures. In the event of extreme high water, stage of 29.5 or higher, a
sandbag closure will have to be placed across the tracks of the Canadian National- Chicago Central
Railroad at approximate station 180 +96. At approximate station 4 +50NA near the lock & dam, a
similar closure must be placed across the tracks of the Canadian Pacific Railroad at a 31.5 -foot
stage. Coordination with officials of both railroads must be carried out prior to closure. The sandbag
closures should have a minimum top width of 2 feet and a minimum base width three times the height
of the closure. Sandbagging should start at the south end of the levee due to its lower elevation.
Due to the location of the sanitary sewer force main at the south end of the levee extra time should be
allowed to sandbag around the sanitary sewer force main.
19. Hawthorne Street pumping station. When the river approaches the gate closing stage of 14 feet,
the station operator should review the manufacturer's operating instructions as furnished under the
original construction contract. He then closes the main circuit breaker, closes the sluice gates in the
gravity outlet, and starts the pumps as described in paragraph 10. The controls are set for three
sequences of pump operation as follows:
Sequence A. Pump No.1 starts at El. 601.5. Pump No.2 starts at El. 602.0 and
runs in parallel with pump No.1. Pump No.3 starts at El. 602.5 and runs in parallel with
pumps Nos. 1 and 2. Each pump stops at El. 600:0
Sequence B. Pump No.2 starts at El. 601.5. Pump No.3 starts at El. 602.0 and
runs in parallel with pump No.2. Pump No.1 starts at El. 602.5 and runs in parallel with
pumps Nos. 2 and 3. Each pump strops at El. 600.0
Sequence C. Pump No.3 starts at El. 601.5. Pump No.1 starts at El. 602.0 and
runs in parallel with pump No.3. Pump No.2 starts at El. 602.5 and runs in parallel with
pumps Nos. 3 and 1. Each pump stops at El. 600.0
When the river recedes to El. 599.5
a. Open the sluice gates in the gravity outlet.
b. Repeat, in reverse order, the steps taken to activate the station.
c. Turn pump control switch to "Off' position.
d. Retain main circuit breaker in 'On" position.
e. Inspect, oil and grease plant equipment, restore tools to proper places, and
replace supplies.
f. Remove fire hazards.
20. Bee Branch pumping station. This open -air pumping station and the adjacent control
shed have been retained from a preceding local project, modified and enlarged with the
addition of a 24 -inch axial flow pump, rated 20,000 gpm at 25.4 feet TDH. New 60 -inch
butterfly valves and operators have been provided for the two 90,000 gpm pumps. The 24 -inch pump
has an automatic siphon breaker. It will use the preceding level control. The winch - operated sluice
gates and the two older pumps have for years been started and operated by manual controls. This
procedure will remain in force. When the 24 -inch pump is turned on it will operate automatically to
keep the ponding area at El. 592. Preparatory and trial -run operation are standard procedures
described in paragraph 10.
21. Bee Branch Pumping Operation. When the river approaches the gate - closing stage of 14 feet, the
station operator should review the manufacturer's operating instructions
furnished under the construction contract and determine that the 72 -inch sluice gate in the 8th Street
manhole is closed, diverting the flow into the ponding area. He will then:
a. Close the Bee Branch sluice gates.
b. Close the main circuit breaker.
c. Push the start button on the motor control panel.
d. If it rains, start the 60 -inch pumps. The maximum ponding stage is El. 602.0.
When the river recedes to the 14 -foot stage and continues falling:
a. Open the sluice gates in the gravity outlet.
b. Repeat, in reverse order, the steps taken to activate the station.
c. Turn pump control switch to "Off position.
d. Retain main circuit breaker in "On" position.
e. Open the 72 -inch sluice gate in the 8 Street diversion manhole
f. Inspect, oil, and grease plant equipment, restore tools to proper places, and
replenish supplies.
g. Remove fire hazards.
22. Harbor closure pumping station.
a. Preparatory and trial -run operations. These are standard procedure described
in paragraph 10.
b. Flood conditions. There is a tendency to retain access to the harbor as long as
practicable, and hence to delay as late as permissible before the harbor is converted into a ponding
area. Consequently, some discretion is warranted in selecting the river stage at which the miter gate
must be closed and the pumps set in operation. As described in paragraph 17b(1), stages of 16 to 17
feet may be considered, depending on precipitation and the forecast of ultimate flood crest. It is not
advisable to delay closing of the gate until the damaging 18 -foot stage has arrived because the runoff
from a heavy local rainstorm greatly exceeds the capacity of the pumps. When the river approaches
the selected gate closing stage, the station operator should review the manufacturer's operating
instructions as furnished under the construction contract. He then takes the following steps.
(1) Close the equalizing sluice gate on the river face of the north abutment.
(2) Close the miter gate.
(3) Open the sluice gate in the pumping station intake.
(4) Close the main circuit breaker.
(5) Push the start button on the motor control panel.
When the river is receding towards the non - damaging stage, it will require about 72 hours to equalize
the pressures on the miter gate so that it may be opened. Thus it will require experience and good
judgment in selecting the best time to close down the pumping station. It is recommended that this
would be three days before the non - damaging river stage is anticipated, and the necessary steps are
in the reverse order from starting the station, thus:
a. Push the stop button on motor control panel.
b. Retain main circuit breaker in the "On" position.
c. Turn pump control switch to "Off' position.
d. Open the equalizing sluice gate on the river face of the north abutment.
e. When the gate pressures are equalized, at or below the non - damaging stage,
open the miter gate as described in paragraph 17.
f. Inspect, oil, and grease plant equipment, restore tools to proper places, and
replenish supplies.
g. Remove fire hazards.
23. Pumping station at Maus Park. When the river stage is predicted to exceed 18.0 feet, close the
gravity gate at river stage 16.0 and start both pumps. Place pumps on automatic operation, which will
take the forebay down to elevation 596.0 when the forebay reaches elevation 596.5, pump No.1 will
start and pump No.2 will start at elevation 597.5 and pump the forebay back down to elevation 596.0.
The pumping station operator should review the manufacturer's operating instructions as furnished
under the original construction contract so that he can closely monitor the operation of the pumping
equipment at the start of pumping.
The following procedures govern the placing in service and operation of the pumping
station during floods.
a. Assure that the main circuit breaker is in the "On" position.
b. Tum the storm pump control switch from the "Off' position to automatic.
c. Close gravity sluice gate.
d. When the pumps start to operate, maintain the station as follows:
(1) Keep the trashrack clear of debris.
(2) Assure that pumps receive proper lubrication and correct any conditions indicated by
undue noise, vibration, or overheating.
24. Maus Park Pumping Operation. When the river stage is falling and falls below river
stage 16.0 feet (elevation 601.0), pumps shall be taken out of operation. With the
continuation of receding stages, the following operations shall be accomplished at the
station.
a. Open sluice gates on gravity sewer.
b. Retain main circuit breaker in the "On" position.
c. Turn stormwater pump control switch to "Off' position.
d. Inspect, oil, and grease plant equipment, restore tolls to proper places, and
replenish supplies.
e. Remove fire hazards.
IV - INSPECTIONS, TESTS, AND OPERATIONS
FOLLOWING FLOOD PERIODS
25. General. Immediately following a flood period or as soon as conditions permit, the
Superintendent should initiate a general cleanup of all flood control facilities, make a
general inspection of the project, and repair all damage to the project works.
Demobilization of flood control activities should include the release of emergency
personnel, an inventory of supplies, and cleaning, storing, and replenishment of equipment and
supplies. Procedures will revert to ordinary maintenance.
26. Levees and floodwalls. As soon as practicable "following high -water periods, the
Superintendent shall initiate a program for repair of all damage to the levee and the
riverbanks adjacent to the floodwalls. The repair program should include replacing
embankment or riverbank materials in eroded areas, relaying or replacing of riprap in
disturbed areas, resodding or reseeding of damaged sodded areas, and the correction of any
settlement or bank - caving conditions affecting the stability of the floodwalls.
27. Drainage structures. As river levels drop to the stages indicated in the tabulation in
paragraph 16, the sluice gates should be opened as soon as possible. Immediately following the flood
period, all gates and structures should be the subject of inspection and cleaning to assure that they
can function properly and to determine the extent of any damage, which may have occurred.
Necessary repair should be completed as soon as possible.
28. Closure structures. When floodwaters fall below the elevation of the sills of each
closure structure as shown in the tabulation in paragraph 16, the gates should be opened as soon as
possible. If the post -flood inspection reveals defects or damage to any components of the closure
structures, such as the toe drains, slope protection, or concrete abutments, the condition should be
corrected as soon as possible.
29. Post -flood report. After each flood, the Superintendent shall compile a post -flood
report and forward one copy to the District Engineer, U.S. Army Engineer District, Clock
Tower Building, Rock Island, Illinois 61201. The report should be a complete flood
history. It should include a log of operations, a daily tabulation of river stages, a discussion of
pertinent factors in operation and maintaining the project, and any other useful information. Operation
and maintenance factors should include problems encountered, weather conditions encountered
(including effects of ice on operation), damage incurred, repairs required, and other significant factors
which occurred during the operation and maintenance of the project during the flood period. The
report should also include a summary of the time and cost of manpower and the quantities and costs
of supplies and equipment, which the protective effort required. The post -flood report, if properly
recorded, well- documented, and readily available to responsible officials, can prove invaluable in
planning for future floods.
30. Semiannual report. In addition to the post -flood report, paragraph 208.10(6) of the
general regulations, Appendix B, the Superintendent is required to submit a semiannual
report to the District Engineer, covering inspection, maintenance, and operation of the
protective works. The importance of regularly scheduled inspections and preventive
maintenance activities is stressed as being the principal insurance against major problems arising
during floods.
31. Report Format. A copy of a suggested report form, which indicates the project features that
should be inspected and reported on, is shown as Appendix F. The inspections and report should be
made in the spring before the normal high -water season and in the fall.
32. Pumping Station Generators Listed below is the information for the power generators located
at the four pumping stations.

City will notify railroads to remove tracks at both ends of the levee closure.
Sandbagging should start at the south end of the levee due to its lower
elevation. Extra time is also needed at the south end of the levee to sandbag
around the sanitary sewer force main.

L &D 11 Tailwater River Stage Gauge Reading: MSL Elev. = 588.2 + L &D 11 Tailwater
River Gauge Reading
A "0.00" Tailwater River Gauge Reading at L &D 11 Equals a 588.2 MSL
Elevation
Train Bridge River Stage Gauge Reading: MSL Elev. = 585.5 + Train Bridge
River Gauge Reading
A "0.00" River Gauge Reading at the Train Bridge Equals a 585.5 MSL Elevation
In summary, this means that the river gauges at both the L &D 11 and the Train Bridge
differ by 2.7 feet. However, using the above conversion formula, both river gauges
correlate to the same MSL elevation.
