Engineering Services Selection for the Asbury Plaza Area Lift Station and
Force Main Project (CIP#7101350)
TO:
FROM:
INTRODUCTION
The purpose of this memorandum is to request authorization to hire IIW Engineers &
Surveyors to provide engineering services for the Asbury Plaza Area Lift Station and
Force Main Project.
BACKGROUND
With the adoption of the Fiscal Year 2007 Capital Improvement Budget, the City Council
established funding (CIP#7101350) for City participation in the extension of sanitary
sewers into new development areas or recently-annexed areas as part of pre-
annexation agreements.
In February of 2006, IIW Engineers completed the Northwest Asbury Plaza Area
Wastewater Pumping Feasibility Report (Report). It outlined the recommended sanitary
sewer system collection system to serve property north of Asbury Plaza. See attached
report. The specific properties that could be served by the proposed system are owned
by:
Motor City LLC
John Herrig
Grand View United Methodist Church
Dean and Patricia Butler
Leo and Arlene Dietz'
Clement and Jeannine Hilby'
Douglas and Eileen Coates'
Laverne and Marlene Brimeyer'
, Currently not within City limits.
The voluntary annexation of the Motor City (Corey) property and the Herrig property
were approved by the City Council in June and July of 2006 respectively. See attached
Exhibit A. The pre-annexation agreement calls for the City to "construct a lift station and
force main sanitary sewer to serve the property."
DISCUSSION
On August 9, 2006, Engineering released an RFP to the public for the Asbury Plaza
Area Lift Station and Force Main Project (see attachment).
The general scope of the project is to prepare a final design, specifications, and a
construction estimate for the recommended sanitary sewer system collection system
described as ALTERNATIVE 4-MULTIPLE WASTEWATER PUMPING FACILITIES on
page 8 of 9 in the Report.
Three firms responded:
1. IIW Engineers and Surveyors, PC (Dubuque);
2. Veenstra & Kimm, Inc. (West Des Moines) with Buesing & Associates
(Dubuque); and
3. WHKS & Co. (East Dubuque, IL).
The proposed system is the only viable system. It requires that multiple lift stations
communicate with each other to take into account the configuration and limitations of
the downstream collection system. IIW and WHKS clearly understand this challenge.
IIW has the familiarity and understanding of the complexities of the recommended
system to be successful. And due to the survey and engineering work already
performed on their part for the Corey Development, their proposed fees ($49,000) are
more competitive than WHKS ($73,500). Engineering concluded that IIW best
responded to the objectives outlined in the requests for proposals.
RECOMMENDATION
Based on the proposals, Engineering recommends that the City retain IIW Engineers &
Surveyors to provide engineering services for the Asbury Plaza Area Lift Station and
Force Main Project.
BUDGET IMPACT
IIW's fee proposal to prepare a final design, specifications, and a construction estimate
for the Asbury Plaza Area Lift Station and Force Main Project is $49,000.
The study will be funded from the FY2007 CIP Budget design appropriation of $127,500
(CIP#7101350). The balance of the design funding is required for other engineering
needs associated with this and other extension projects.
ACTION REQUESTED
I respectfully request approval to hire IIW Engineers and Surveyors, PC to provide
engineering services for the Asbury Plaza Area Lift Station and Force Main Project.

2. STUDY AREA INFORMATION AND PROPOSED PUMPING

PURPOSE
The purpose of this report is to present a summary of the evaluation of the feasibility of
providing wastewater pumping to the land north and west of Asbury Plaza. Wastewater
pumping will be necessary because of the topography of the area. The evaluation
considered the use of one regional pumping station to serve the study area and the use of
multiple pumping stations to serve the study area and some other alternatives or
variations.
The City sewer system in the Catfish Creek basin is at times overloaded. The discharge
from this report's study area would, therefore, be directed to another sewer branch (West
32"d Street) to avoid additional flows in the Catfish Creek sewers. A thorough review of
the flows in, and capacity of, the West 32"d Street sanitary sewer system was not;art of
this evaluation. However, the capacity of a portion of the upper end of West 32" Street
sewer system was part of this study, so the immediate impact on the existing sewers
could be considered.
Both the developer and the City want, what is to them, a cost effective solution for
wastewater pumping. To a developer this usually means the lowest initial cost facilities
that meet the needs of a project and conforms to applicable regulations. For a City, cost
effective means somewhat more. The costs of maintenance and operation must be
considered. The City has indicated a desire to have pumping facilities that serve the
largest area for the least cost, thereby reducing a "per acre" cost.
Based on this study, the developer will have a better idea of what will be needed for
wastewater pumping facilities to serve the planned development. Preliminary cost
estimate will allow financial planning of the development and/or for partnering
negotiation. Some approximate locations for the pumping station or stations and the
pressure main routes will aid in site planning and design.
The City will be able to use this study to determine areas that can be served by extensions
of City infrastructure and the sum of the costs associated with the extensions. The City
will be able to determine future maintenance and operation costs based on the selected
alternative.

STUDY AREA
The study area for this wastewater pwnping feasibility evaluation is generally north and
west of Asbury Plaza. This area is located in sections 8, 9, 16, and 17 of Dubuque
Township (T89N, R2E) and covers nearly 800 acres. The studied area generally extends
from near Asbury Road on the south to Derby Grange Road on the north and from
Kennedy Road on the east to the City of Asbury Corporate limits and Woodmoor Estates
on the west.
Exhibit I is an aerial photograph ofthe study area.
This area is at the upper end of the Cloie Branch drainage basin. Surface water runoff
flows to the Cloie Branch to the Little Maquoketa River east of Durango. The Little
Maquoketa River flows into the Mississippi River just north of the John Deere Dubuque
Works.
The area is currently used for agriculture including row crop, forage production, and
animal pastures. Severe prehistoric erosion has carved steep walled ravines that serve as
the drainage ways to the Cloie Branch. Ground slopes range from approximately 2
percent to nearly vertical, the steepest walls of the ravines.
Property owners in the subject area include:
Motor City LLC
John Herrig
Leo and Arlene Dietz
Clement and Jeannine Hilby
Douglas and Eileen Coates
Laverne and Marlene Brimeyer
Grandview United Methodist Church
It is the Motor City property and the Herrig properties that are currently being developed.
The church has discussed the possibility of development, but has no definite plans or
schedule. The Dietz, Hilby, Coates, and Brimeyer properties are included because they
are in the drainage basin adjacent to planned development and because the development
frequently follows when sanitary sewer is made available.
The Motor City property has a gross area of approximately 152 acres. Of this gross area,
some 13 acres are in un-developable ravines. The net area would be 139 acres.
However, typical development of this type of land is perhaps only 90% when roadways,
green spaces, storm water detention facilities, etc. are deducted. The effective area of the
Motor City property to be developed is thus, 125 acres.
20f9
The Herrig property gross area is approximately 123 acres. Over 37 acres of this parcel
can not be considered developable because of the deepest and steepest ravine and
questions about access to a rather small portion in the west end of the parcel. The net
developable is 86 acres. If a 90% utilization is assumed, the effective area of the Herrig
property to be developed is 77 acres, more or less.
The remainder of the study area has a gross area of approximately 523 acres. The
effective area to be developed has been estimated to be 353 acres.
For the purposes of this study, the estimated total effective area to be developed is 555
acres. At the present time only a portion of the Motor City property has been annexed.
Plans call for a mixture of commercial use, office use and warehousing. Herrig and the
church are considering single family residential development. For the purpose of this
study the future development will be assumed to be single family residential.
Based on the anticipated land usage, the effective area of 555 acres is divided into two
primary uses, residential and commercial. The estimate is 125 acres of commercial usage
and 430 acres of residential usage.

W ASTEW ATER FLOWS
The Iowa DNR design standards do not establish specific criteria for estimating flow
rates for pumping facilities. However, the DNR design standards do have specific
criteria for sanitary sewers.
For single family residential development the DNR established a density of 10 people per
acre. The average flow, according to the DNR, is to be 100 gallons per day per person.
Thus, the average flow from residential development is to be assumed to be 1,000 gallons
per day per acre.
The DNR design standards also provide information about estimated peak flows. The
peak flow for sewers ranges typically from 2 to 4 times the average flow. It would
appear that a peak to average ratio of 4 might be reasonable and conservative for
collector sewers. However, a peaking factor of 2.0 to 2.5 times the average flow rate
seems reasonable for pumping station design because of the equalization nature of wet
well storage and typically larger contributory areas.
The DNR design standards set forth a commercial area sewer flow rate of 5,000 gallons
per day per acre. The DNR has indicated that this flow rate is a peak flow for sewer
design. Using a 4.0 peak to average ratio for sewers, the average flow would become
1,250 gallons per day per acre. If the peaking factor suggested above for pumping
stations of 2.5 is applied to the calculated average flow for commercial area, the peak
flow rate becomes 3,125 gallons per day per acre.
The study area includes an estimated effective area for commercial development of 125
acres. The estimated effective area for residential development is 430 acres. Based on
these areas the peak wastewater flow rate is as follows:
Commercial Area
125 Acres @ 3,125 gpd/acre equals 390,625 gpd or 272 gpm
Residential Area
430 acres @2,500 gpdlacre equals 1,075,000 gpd or 747 gpm
Total Study Area Flow
272 gpm plus 747 gpm equals 1,019 gpm
The residential area flow rate comes from three district areas. One area is the Herrig
property. The second is the area north and east of the commercial area and owned by
Coates, Brimeyer and Grandview Church. The third is the area south and west of the
commercial area and owned by Hilby and Dietz. The division of the residential flow rate
estimate is:
40f9
Herrig
Coates, Brimeyer, and Church
Hilby and Dietz
134 gpm
292 gpm
321 gpm
It should be noted that a portion of the Hilby farm drains to the northeast toward the
Motor City commercial area. Another portion of the Hilby farm plus the Dietz property
drains to the northwest toward the unbuildable western area of the Herrig property. The
drainage split is approximately split in half to each drainage way. Thus, the sewage flow
is split 50% to each drainage way.

RECENING SEWER CAPACITY
Wastewater from the study area is to be pumped to the east to avoid additional loading of
the Catfish Creek sewer system. The designated force main discharge point is a manhole
just south ofthe Grandview United Methodist Church. This flows in an 8-inch sewer line
that runs southeast and discharges to a 12-inch sewer west of Eisenhower School. This
12-inch sewer flows east to Carter Road discharging into an 18-inch sewer. The 18-inch
sewer line flows along Carter Road and discharges into a 21-inch sewer in West 32nd
Street. The 21-inch sewer line size becomes 24-inch as additional sewers are connected
along West 32nd Street. The 24-inch sewer line is connected to the 36- inch Couler
Valley sewer east of Central Avenue. As previously indicated, the evaluation of this
entire sewer system was not part of this wastewater pumping feasibility report.
As part of this study, the capacity of the 8-inch sewers between the church and the 12-
inch interceptor sewer was performed. One 8-inch sewer segment in the soccer complex
has a slope of 0.7%. This provides a full capacity of 455 gallons per minute (gpm). The
DNR design standards indicate that sewers are to be design for no more than 75% of the
full depth, thus, the theoretical design capacity of this sewer segment is less than 300
gallons per minute.
An alternate force main connection point was identified during evaluation of this 8 inch
sewer. This alternate discharge point is manhole 5 on the north side of the Northwest
Arterial. This discharge location bypasses the critical 0.7% slope sewer segment in the
soccer field. The critical sewer slope below this alternate connection point is 1. 8 % based
on IIW field surveys. The 8-inch sewer at a slope of 1.8% has a full capacity of 720 gpm
and a DNR criteria design capacity of 432 gpm.
A cursory review of the City furnished drawings for the 12-inch segment of interceptor
sewer indicates a critical slope of I % or so. The full capacity of a 12- inch sewer at a 1%
slope is 1,580 gpm. The DNR criteria would indicate a design capacity of948 gpm.
During review of the capacity of the 8-inch sewer segment, an additional advantage of
the alternate discharge point (manhole 5) was noted. This discharge location is 53 feet
lower than the sewer at the church. This lower elevation reduces the total head on the
pump or pumps and thus the power requirement.

ALTERNATIVES
As part of this feasibility study alternatives for handling wastewater were developed and
evaluated. The alternatives considered were:
I. Construct a wastewater treatment facility.
2. Construct a single regional wastewater pumping facility to serve the entire study
area.
3. Construct a single regional wastewater pumping facility with flow equalization
storage to allow a smaller pumping rate.
4. Construct multiple pumping facilities with limited capacity utilizing a single
common force main.
5. Construct a temporary pumping facility for Motor City development discharging
to the existing Asbury Plaza sewer system.
ALTERNATIVE I-WASTEWATER TREATMENTFACILTY
The construction of a wastewater treatment facility is not a feasible option. A 1.5 million
gallon per day treatment plant would take 3 or more years to get permitted and
constructed. It would be most difficult to find a location for a treatment facility that
would meet the DNR requirement for 1,000 feet of separation from existing inhabited
structures. Effluent limits for treatment and discharge to the Cloie Branch would be very
restrictive for ammonia and bacteria. A treatment facility constructed in the ravine on the
west end of the Herrig property would have difficult access and possible flooding
concerns. This location would require significant sewer extensions. The operation of a
second treatment facility for the City of Dubuque would have substantial operational
costs including sludge disposal.
ALTERNATIVE 2- SINGLE REGIONAL W ASTEW ATER PUMPING FACILITY
A single regional pumping station with a capacity of 1,020 gallons per minute is not a
feasible alternative. The designated receiving sewers and subsequent down stream
sewers do not have the design capacity to handle the required flow rate. It is likely that
existing sewage flows in the 12-inch, 18-inch, etc. have taken a significant portion of the
design capacity. A single regional pumping station would be constructed in the ravine on
the Herrig property. This location has difficult access and flooding concerns. Substantial
sewer construction to this site would be necessary including some on Hilby property. A
248 horsepower motor would be needed to pump sewage at 1,020 gpm to the alternate
discharge point.
70f9
ALTERNATIVE 3-SINGLE REGIONAL WASTEWATER PUMPING FACILITY
WITH FLOW EQUILIZA TION STORAGE
It is possible that a flow equalization storage tank could be constructed at a single
regional pumping station. The flow equalization tanks would serve to reduce peak flows
so that wastewater could be pumped at an average flow rate rather than the estimated
peak flow rate. The equalization facility would have a volume of up to 500,000 gallons.
The resulting pumping station capacity would be approximately 407 gallons pet minute.
It is unknown if the DNR will approve this concept. The separation criteria may be
applied to the flow equalization storage tank by the DNR. The storage facility would be
constructed of coated steel or concrete and would require additional pumps to fill or
drain. The storage of untreated sewage may result in odors in a residential neighborhood.
Permitting and construction would take 2 years or more. As with the larger regional
pumping station, access would be difficult. There would be flooding concern. Significant
sewer construction would be necessary, some on Hilby property. Regular tank cleaning
would be part of the operational costs. The pump motors for the average flow pumping
station would be 84 horsepower.
ALTERNATIVE 4-MULTIPLE WASTEWATER PUMING FACILITIES
After development of unfeasible or difficult alternatives for wastewater handling in the
study area, a multiple pumping station concept has been developed and evaluated. Two
or three pumping stations would be installed to serve the proposed development of Motor
City and Herrig. A fourth station would be needed for future development. This multiple
station concept will allow the City of Dubuque to consider the adjacent properties for
annexation. The discharge from the pumping stations would utilize a common force
main discharging to manhole 5 on the south side of the soccer field. The pump station
design and common force main would limit the flow to 400 gpm and thus limit the
impact on the receiving sewer. Multiple pumping stations would allow for phased
construction. It would not be necessary to construct all pumping stations, sewers and
force mains to allow initial development to proceed. The pumping stations could be
located at higher elevations out of the flood plain thereby reducing static lift and total
pump head (power). Forty to sixty horsepower pumps are required. This multiple
pumping station and common force main is the recommended alternative.
ALTERNATIVE 5-TEMPORARY PUMPING FACILITY FOR MOTOR CITY
DEVELOPMENT
The possibility of building a temporary pumping facility to serve a portion of the Motor
City development has been suggested. The capacities of the existing Asbury Plaza
sewers and pumping station have not been evaluated as part of this study. The City has
not commented on this idea. It should be noted that the time required to design, permit
and construct the first of the multiple pump stations would not be significantly longer
than constructing a temporary pump station and smaller force main. Building the
permanent pumping station would be less total cost than adding the cost of temporary
pumping facilities.
