Similar Projects
Ayres Associates has completed many projects
similar in scope to the work included in this request
for proposal, including major stormwater outfall
projects and smaller utility operational improvement
projects. Listed below are noteworthy projects we
' have completed in the past five years that are similar
to the work anticipated under this contract.
Canal Importation Pond and Outfall
Design
City of Fort Collins
This project involved reducing spills from two
drainage ditches that currently affect approximately
1 175 homes. Project included complex hydraulic
modeling to determine ditch spill quantities and
mapping of existing floodplain. Project included
design of two regional detention/water quality ponds
and more than 4,000 feet of large diameter (up to
102 inches) storm sewer and associated laterals and
' inlets. Inlets will incorporate water quality product
"Snout" to improve water quality in downstream
receiving waters. Project included design of round
version of Bureau of Reclamation Type 10 hanging
baffle structure.
North East College Corridor Outfall
(NECCO)
City of Fort Collins
This project includes the design of a large diameter
storm sewer in combination with a regional detention
and water quality pond with 38 acre-feet of storage
in a highly urbanized area that recently was declared
a blight and will receive tax incremental financing for
infrastructure improvements. The system will
ultimately outfall into the Dry Creek Connection
Channel, which Ayres Associates is also designing.
The project has included survey, photogrammetry,
geotechnical analysis, hydrologic and hydraulic
modeling, preparation of construction plans and a
drainage report, and quantity take -offs.
Washington Avenue Outfall Phase 3
Stormwater Improvements
City of Loveland
This project involved investigating and designing
Phase 3 of storm sewer outfall system. Required
topographic surveying, utility potholing, hydrologic
modeling using CUHP and UDSWMM, complex
hydraulic analyses using HEC-22 methodology,
custom inlet design, evaluation and design of
numerous water quality improvements, construction
drawings, and specifications.
Dry Creek Sheridan Reach Flood
Control Improvement
City of Cheyenne
Project involves designing diversion of all but five-
year storm flows off Dry Creek and into series of
three detention ponds before discharging detained
flows back into Dry Creek downstream of constricted
area. Existing condition hydrology was prepared with
HEC-1 model, which was updated to reflect project
improvements. Project also involved design of major
pedestrian underpass under arterial road in
coordination with City of Cheyenne Parks
Department.
Pleasant Valley Pipeline Turnout
Structure
City of Fort Collins
The Pleasant Valley Pipeline Turnout Structure
project involves redesigning a turnout structure to
minimize sediment entry and designing a self-
cleaning "traveling screen" facility to remove organic
debris. The 8.5-mile buried pipeline was constructed
in early 2004 and carries Poudre River water from
the Monroe Gravity Canal to the water treatment
plants below Soldier Canyon Dam during the
summer. In winter, the flows are reversed, carrying
water from the Soldier Canyon outlet of Horsetooth
Reservoir to Greeley's Bellvue Treatment Plant. The
system — a joint project of the City of Fort Collins, the
AWES
ASSOCIATES
' City of Greeley, and the Tri-Districts — is designed to
reverse the flow direction by gravity without the need
for pumps, associated infrastructure, and power
costs.

Project Approach/Philosophy
1
Overall Philosophy
Ayres Associates has benefited greatly from working
with the City of Fort Collins within the guidelines of
the APDS process on numerous projects. Because
of this experience, our overall philosophy of how we
approach project design'has changed for the better.
As current partners with the City of Fort Collins, we
recognize that an entire community of resources is
available to help the City meet their objectives for
utility services related to stormwater, water,
wastewater, and electric power. Ayres Associates is
included in those resources, along with other
consultants, utility providers, contractors, City staff
and residents, City businesses, and Colorado State
University. We are not alone as we solve problems —
instead we work collaboratively at a design table
large enough to accommodate internal and external
stakeholders to find the best possible solution and
the highest quality product for the City and the
community through the project development and
design process. Once project objectives are
identified, relevant resources can be identified to
help define the problem, identify potential solutions,
and select an optimal solution in the overall best
interests of the City. We only wish that all
communities would adopt a similar approach to
identifying and solving problems.
Ayres Associates' staff is also fully aware of the
City's Triple Bottom Line or People, Planet, and
Profit approach to developing solutions. In fact, three
of our team members, including Andrea Faucett and
Chris Pletcher, have recently finished reading the
book by Andrew Savitz titled "Triple Bottom Line" to
better understand the City's objectives.
For some projects, functional operation of the utility
is the primary objective, such as the Pleasant Valley
Pipeline Screen project. For other projects, utility
performance objectives are combined with
environmental restoration goals, such as the CIPO —
Red Fox Meadows detention ponds project. Not
every project has the same issues, and as a result,
different resources may be relevant to the spectrum
of potential solutions.
Ayres Associates' staff thrives in this multi -objective
environment, and we surround ourselves with
partners whose expertise complements our own.
Some of the partner relationships are also direct
contractual relationships, as with engineering
subconsultants. However, many of our partners are
not formally bound to Ayres Associates, but are a
part of the larger "Community of Resources"
available to the City. Some of our partners are even
other consulting firms, as with the collaboration
between Anderson Consulting Engineers and Ayres
Associates on the CIPO project and between
Stantec and Ayres Associates on the North College
Sanitary Sewer Evaluation. We believe in bringing
the best expertise to the table for the City's benefit,
whether that comes from our internal resources,
from other engineers, from consultants or
contractors, or from the community at large. We
consider the design table to be large enough to
provide a seat for all the relevant resources needed
for a project, and yet circular so that one resource is
not considered more valuable than another.
To illustrate this concept of a "Community of
Resources" we have identified significant resources
available to the City that are relevant to issues faced
by the Fort Collins Utilities and shown them on the
exhibit following in this section. Certainly other
resources are available as well. In this exhibit we
want to show that the City is not limited to the
resources of any one firm or stakeholder, but that we
all provide our individual input and expertise toward
the best solution for the City. In the exhibit, blue
colors indicate formal relationships with the City,
typically through contracts. Indirect relationships are
shown with green colors, and indicate shareholder
status as a customer or recipient of City services but
not through a formal contract. It is important to
recognize and identify informal shareholders as
early in the project as possible to understand their
concerns and allow the project to respond to them
as appropriate. In some cases, the response will be
to inform and educate the shareholder as to the
balance of various project priorities. At other times,
external shareholders will bring new issues to light
that will need to be addressed in the project design.
In essence, the "Community of Resources" concept
embodies the City's APDS process and the Triple
Bottom Line approach to developing solutions.

Project Understanding
In preparation for this proposal, our project team has
made a concerted effort to become familiar with all
aspects of the Magnolia Street Stormwater Outfall
project and the challenges associated with this
design through the following:
• Review of the Old Town Basin Master Plan
and related documents
• Review of the Old Town Water Quality
Master Plan for Howes, Udall, and Magnolia
Basins
• Review of utility location information
provided by the City and pulling a One -Call
Test Ticket for the project area to determine
other dry utilities located within the project
corridor
• Project site reconnaissance
• Numerous meetings and conversations with
City staff, including Master Planning and
Capital Project staff
• Meeting with Tracy Lyman of Lyman Henn
to discuss issues/concerns with the possible
tunneling and/or jacking locations
The Magnolia Street Outfall project is one of five
remaining major storm sewer improvements and two
minor storm sewer improvements within the Old
Town Basin. As noted in the Master Plan, the proper
function of the Oak Street Outfall, the Whedbee
Street storm sewer, and the Myrtle Street storm
sewer all rely heavily on the prior construction of the
Magnolia Street outfall, either to not shift flooding
impacts from area to area within the Old Town Basin
or to provide an adequate outfall. The specific limits
of this project extend from the Poudre River on the
east to Shields Street on the west and generally
include the area between Olive and Mulberry.
Similar to the CIPO, Locust, and Sheldon Lake
projects, the project corridor is within a highly
urbanized setting. This is not surprising because
these are the areas that were generally built before
the City established stormwater regulations.
According to City staff, residents from the area
around Whitcomb and Magnolia have reported
flooding as recently as July. In addition, City staff
took some debris line photographs after the July 20
storm, in and around the Mulberry and College
intersections where the water looked precariously
close to entering adjacent businesses. According to
the Master Plan, the basin is generally served by
small -diameter storm sewers and a heavy reliance
on street flow capacity. While a number of very wide
streets are within the basin (including Magnolia), the
ability of the streets to convey flow is greatly
impacted by the high crowns of the cross streets
running north and south.
The Master Plan states there are 135 structures
damaged by the 10-year storm and 259 structures
damaged by the 100-year storm within the project
corridor. In addition, a number of public facilities,
including schools, the old post office, and the Lincoln
Center, are impacted by flooding in this basin. More
than 19 streets would be overtopped by more than
1 foot of water during a 10-year event, and nine
would be overtopped by more than 2 feet during a.
100-year event within the project corridor. The
structure damages for the 100-year or even a
10-year event within the project corridor are
enormous. In addition, other costs are associated
with the flooding that although they are a little more
difficult to quantify, are also significant. Flooding
within the Magnolia corridor would greatly impact the
ability of emergency response vehicles to respond
due to the depth of water flowing in the streets.
In addition, flooding in an urban setting such as the
Magnolia/Mulberry corridor has serious
environmental impacts because the water would
overload the sanitary sewer collection system and
treatment plants. Potential sanitary sewer overflows
would contaminate homes and businesses and
expose the City to potential EPA fines and penalties.
Also, the flood waters would become contaminated
with oil and other household chemicals it comes in
contact with, all of which would be conveyed
downstream to the Poudre River.
One other unique feature of the Old Town Basin is
the large number of basement apartments because
of the proximity to Colorado State University. Many
of the basement apartments are occupied by
students who rely solely on cell phones for
communication, so in the event of a flood, they
would be very difficult to notify. Some of these
intangible benefits may play a much larger role in
developing the objectives of the Magnolia Street
Outfall project as the City continues to embrace the
Triple Bottom Line approach to solving problems.
The proposed mitigation measures outlined in the
selected plan provides for additional inlets and
large -diameter storm sewer to capture and convey
the 100-year flood flows to the Poudre River. The
JAWS
ASSOCIATES
I
n
main trunk of the proposed storm sewer would be
built along Magnolia, with laterals extending up a
number of connecting streets. Although the original
Master Plan called for building a water quality pond
on the Old Pickle Factory site at the outfall, that
concept has been eliminated. The selected plan now
calls for building a diversion from the Magnolia storm
sewer at Whedbee Street that would convey the
water quality flows for the project area into the Udall
water quality pond, which has excess capacity.
Constructing the selected plan of improvements will
reduce the number of damaged structures to 34 in a
10-year storm and 129 in a 100-year storm. The flow
reduction in Magnolia Street could be as great as
1,200 cubic feet per second (cfs).
Of equal importance, constructing the Magnolia
Street Outfall improvements will reduce emergency
response time during a flood event; reduce damage
to personal property, such as vehicles; reduce
closure time for businesses impacted by flooding;
reduce the frequency of basement flooding; and
reduce the chances of overloading the sanitary
sewer system with flood waters and contaminating
residences and businesses.
Project Approach
Ayres Associates approaches every project with a
sincere effort to develop the most cost-effective
solutions for the defined project objectives. While we
have the expertise and experience to handle the
most complicated stormwater modeling, analysis,
and design problems, we approach every project
from a common-sense perspective that doesn't
overlook simple solutions. From the Rational Method
to ModSWMM and unsteady EPA SWMM modeling,
from the Manning's Equation to highly complex
pressure flow pipe hydraulics, from big picture
master planning to detailed micro -engineering, from
simple steady state channel hydraulics to
complicated scour analysis at bridges, the City can
be confident that Ayres Associates is not only highly
capable, but also will provide the best possible
project for the available funding.
Alternative Analysis Phase
As with previous stormwater utility design projects,
Ayres Associates envisions that the first phase of
the design will incorporate a period of data collection
and Alternative Analysis. Ayres Associates and the
rest of the APDS team will use the Old Town Master
Plan and the selected plan design for the Magnolia
Street Outfall as the foundation or starting point for
the design process. A tremendous amount of work
has already gone into developing the Master Plan
solution, and that information will be reviewed in
detail, understood, and used as we move forward.
As additional information is gathered, and
particularly as the City's selected contractor provides
constructability insight into the final design, the
preferred solution will evolve from the Master Plan
design.
We understand the Master Plan already looked at
the sanitary sewer crossings when developing the
conceptual design. This is critical because of the
large number of sanitary sewer crossings within the
corridor and the large -diameter storm sewer that is
being proposed. We have included an exhibit at the
end of this section that shows the proposed storm
sewer alignment and the existing sanitary sewer and
water lines for reference. Unfortunately, quite often
other utilities, particularly fiber optic duct banks, can
require adjustments to the profile. Our staff pulled a
Utility Notification Center of Colorado (UNCC — or
"One -Call") Test Ticket for the project area and
found the following utilities listed: Comcast cable
(historically copper coaxial cable, but recently
converting to fiber optic within neighborhoods),
CSU-Fiber, CSU Utilities, City of Fort Collins (water,
sewer, storm, electric, and traffic), Level 3
Communications (typically fiber optic), MCI (typically
fiber optic), Xcel Energy (gas and electric
distribution) , and Platte River Power Authority
(electric and fiber optic).
We may need to look at other alternative measures
for providing flood mitigation in this area in addition
to the "big pipe" option. These alternatives could
include maximizing the use of the street conveyance
in combination with a storm sewer. This alternative
would be complicated by the significant crowns in
the cross streets running north and south along the
project corridor. In fact, some of the areas upstream
of the high crowns were accounted for as detention
ponds in the current hydrologic model. Another
alternative would be to investigate the use of a
channel within the street corridor. Going even further
outside the box, this channel could also incorporate
a bio-swale for water quality treatment. While these
options would not eliminate the need for new storm
sewer within the project corridor, our team is willing
to creatively consider them along with the more
traditional alternative shown in the Master Plan.
JAMMIS
ASSOCIATES
'
Because of the changing political climate within the
City, it is likely that the main objective of providing
flood mitigation may need to be balanced against
other objectives such as reduced environmental
impacts or even enhancing the natural environment.
One possible way of enhancing the environment is
by providing more localized water quality treatment
'
along the project corridor in addition to what is being
provided at Udall. Examples of possible localized
treatments include the incorporation of segments of
permeable pavement and the use of bio-boxes and
bio-swales. Ayres Associates recently completed
designing a bio-swale system as one option for the
'
North College improvements from Vine to Conifer.
We also recently completed designing three
bio-boxes for the Loveland Washington Avenue
Phase IV stormwater improvements, which will be
built in 2010.
Tunneling/Jacking
Ayres Associates has met with Tracy Lyman of
Lyman -Henn to review the project specifics as
outlined in the Old Town Basin Master Plan. Based
' on this discussion, Tracy Lyman has offered the
following input on the tunneling design:
The project includes four potential tunnel sections:
'
the primary outfall under Riverside Drive; a second,
water quality outfall to the north under Riverside
Drive; a crossing below Mason Street, including the
'
railroad tracks there; and a crossing below College
Avenue. A combined tunnel drive is also worth
considering from Mason Street to College Avenue to
minimize open cut disruption and two tunnel shafts
at this location. Anticipated ground conditions
include sandy silt and silty sand soils with minor
gravel and cobbles. Groundwater is expected within
'
or somewhat above the tunnel horizon. The pipe
diameter is planned as 102-inch RCP at Mason and
College and 114-inch RCP at Riverside. We have
assumed that the depth to tunnel crown is at least
20 feet. Shallower tunnel depth will complicate
tunneling due to a lack of confining stress at the
tunnel horizon with resulting higher risk of ground
loss and surface settlement above the tunnel. All
anticipated tunnel drives are approximately 150 feet
'
except the combined drive from Mason to College,
which would be about 900 feet.
We anticipate that the most feasible tunneling
' methods for these drives would likely include
dewatering and hand mining or dewatering and
using a simple wheeled excavator or tunnel shield
tunnel boring machine. These methods offer precise
grade control, the flexibility to deal with variable
ground conditions, and are compatible with the
required pipe sizes. Either method would require
continuous initial tunnel support consisting of ribs
and wood lagging, steel liner plate, or jacked steel
casing pipe. Temporary support would likely be
erected or jacked into an approximately 10- to
12.5-feet excavated opening.
Potential tunneling issues to consider during project
planning and design include the dewatering system
requirements and feasibility of dewatering based on
soil conditions and required drawdown, location and
availability of shafts and contractor work areas
(particularly at Mason and College), and required
tunnel face control measures depending on soil
conditions. These issues will be addressed
collaboratively with the project team, including the
project tunneling contractor, and be based on the
collective team experience in the Fort Collins area.
The potential "long tunnel' between Mason and
College would eliminate the need for two reception
shafts and potentially minimize third party
disturbance in the intervening block because the
tunneling operations could be staged from only one
shaft location and by eliminating the open cut pipe
section between Mason and College. The project
team will evaluate the project cost premium for a
continuous tunnel and compare the premium to the
community benefit so that a rational decision can be
made as to the desirability of this option.
Diversion of Water Quality Flows to
Udall
The Old Town water quality Master Plan
recommends constructing a reinforced concrete
diversion structure at the intersection of Whedbee
and Magnolia Street to divert the Magnolia water
quality flows to the Udall water quality pond. The
diversion would include the construction of a 60-inch
RCP pipe that would follow Whedbee Street to the
north and then turn east on Oak Street before
boring/jacking underneath Riverside and the railroad
tracks and connecting into the existing energy
dissipation box. The interesting thing about the
proposed design is that it calls for a separate
boring/jacking underneath Riverside and the railroad
rather then tying into the existing Oak Street Outfall
at the intersection of Whedbee and Oak Street. Most
likely the Oak Street outfall does not have sufficient
capacity to handle the additional 172 cfs from the
AVMS
ASSOCIATES
Magnolia water quality flows. However, it should be
noted that the diversion of the water quality flows
would be during the more frequent 80th percentile of
one-half of the two-year storm. During those types of
events, the Oak Street Outfall should have adequate
capacity to accept additional flows from Magnolia.
However, it would be important to verify that during
the major flood events, the Magnolia Street Outfall
does not surcharge the Oak Street Outfall. This
should be investigated further by preparing an EPA
SWMM model of the two connected systems,
because there would be a tremendous cost savings
if a secondary boring was not required under
Riverside and the railroad.
Construction Impacts
Because sections of the project are within areas that
have significant business activity, construction
scheduling and sequencing must be considered to
minimize impacts to the extent possible. It is also
quite possible that this project will be phased
(because of the high cost), which will also need to
be accounted for in the design. As noted in the
previous section on boring and jacking, impacts to
areas of high traffic activity can also be reduced
depending on the length and type of boring/jacking
used. Of course the impacts need to be weighed
against the significant costs associated with boring
and/or jacking. Considering our project team's
experience with numerous storm sewer construction
projects in highly urbanized areas during all months
of the year, we are confident that we can provide
valuable input to the team on this issue.
■ Cache La Poudre River Impacts
Although the proposed water quality pond shown in
the Master Plan at the downstream end of the
Magnolia Street outfall will not be constructed due to
topographic and site limitations, the outfall will still
discharge into the Poudre River. Our understanding
is that the area shown in the Master Plan known as
the Old Pickle Factory site may now be used as
either a gateway entrance into the City or for a "solar
' array" for energy generation. It is important to note
that the site is also immediately adjacent to the
Mulberry Water Reclamation Facility. If the site is
going to be developed as either a gateway or a solar
array, then the Magnolia street outfall will likely need
to be constructed through the site before
redevelopment of the Old Pickle Factory with.the
actual outlet as close to the river as physically and
environmentally feasible. Two major considerations
at the outfall will be the need for energy dissipation
and impacts to any existing wetland or riparian
vegetation. Steve Long of Cedar Creek
Environmental has walked the area adjacent to the
Poudre River where the outfall may be placed and
provided the following input:
The objective of this site review was to determine
the potential for environmental issues that would
need to be addressed during the design phase of
this project. The area in which the outfall would be
potentially located consists of a broad, nearly level
upland lying above the elevation of the adjacent
railroad tracks and Riverside Avenue to the south.
This upland supports a variety of grass and forb
species with no wetland communities present. At the
eastern end of this upland, steep, nearly vertical
slopes lead down to the banks of the Cache la
Poudre River. These slopes are overlain, in some
areas, with slabs of concrete and support primarily
upland shrub and tree species.
A comparatively narrow, discontinuous wetland
fringe occurs along the banks of the river where the
steep slopes give way to a more level bank features.
This fringe supports herbaceous wetland plant
species where sufficiently level areas have
developed. There does not appear to be habitat
present for the Ute ladies -tresses orchid (Spiranthes
diluvialis) or the Colorado butterfly pant (Gaura
neomexicana .ssp. coloradensis). There would be
no issues associated with these species.
Similarly, there does not appear to be habitat
present for the Preble's meadow jumping mouse
(Zapus hudsonius preblei). This species, however, is
known to occur upstream, and the project area could
be used as a travel corridor. Therefore, it would be
necessary to conduct a brief site survey at the outfall
site and apply to the USFWS for a negative
declaration of effect. The need to delineate wetlands
at the outfall site would be dependent upon final
outfall site selection and whether any of the fringe
wetlands would be impacted by construction.
The release of high volumes of water on an
occasional basis would not likely negatively impact
the wetlands along the riverbanks assuming that
such flows would not be erosive in nature. The likely
outcome of calculated flow releases would be a
temporary enhancement of existing wetland plant
communities.
Mmos
ASSOCIATES
tAyres Associates' staff is familiar with the design of
a variety of energy dissipation structures, having
most recently completed one for the CIPO project
' and the Sheridan Reach Dry Creek improvements in
Cheyenne. One possibility for this outfall, given the
existing trail on the other side and aesthetic
' concerns for the area, is to place the storm sewer
and energy dissipation structure below grade and
have the storm flows access the Poudre River
through a "bubble up" outlet. The disadvantage with
this type of system is that the lower portion of the
outlet system will always have a certain level of
water inside it. If the profile allows, the energy
dissipation could also be provided by using a
significant drop manhole on the upstream side of
Riverside before the boring under the road as was
' done with the Locust Street outfall design. Lastly,
the energy dissipation could be placed immediately
adjacent to the river with the goal of limiting its
' visibility by placing the structure flush with the
embankment. It should be noted that any
modifications made within the Poudre River
floodway as part of the construction may require a
' FEMA CLOMR/LOMR process.
Communication and Quality Control
' Large, highly visible projects with social, economic,
and environmental issues (triple bottom line) require
that significant importance be placed on
collaboration, communication, and quality control.
Ayres Associates is committed to the APDS process,
which provides a means for outstanding
collaboration. In addition, the Ayres Associates staff
' prides itself on providing high-level quality control
and communication. As residents of the City, our
staff is fully aware of the values, issues, and political
' environment that exist locally. The need for open
and transparent communication at all levels, up to
and including City Council, is extremely important on
' projects like this. We would further emphasize our
focus for this project by taking the following
measures:
' Conduct regular progress meetings with
promise to "check ego at the door"
• Provide commitment to include other
' Potentially Affected Individuals and/or
shareholders in the process as
recommended by City staff
• Provide meeting minutes for all progress
meetings and other key meetings
• Support City staff at public meetings, work
sessions, and City Council meetings
• Prepare project work plan and schedule with
key milestones at project initiation
• Conduct quality assurance/quality control
review for each submittal by the Ayres
Associates project manager
• Field verification of topographic survey
• Provide cell phone access to project
manager and project engineer throughout
the entire project
• Provide commitment by team members to
return phone calls or emails within 24 hours
of receipt (sooner if possible)

Scope of Work for the Magnolia Street Stormwater
Outfall — Phase I - Alternative Analysis, Phase II -
Detailed Preliminary Design
Note: This Scope of Work has been broken out into
two phases based on the traditional process that the
City of Fort Collins goes through in developing the
best design. Phase I will be the Alternative Analysis
phase, which includes the time and personnel
necessary to thoroughly investigate the Master Plan
concept and develop possible alternative solutions.
Phase 11 will be the Detailed Preliminary Design
phase, which will include the time and personnel
necessary to bring the selected alternative design to
a point where construction drawings and more
detailed cost estimates can be developed.
Phase I — Alternative Analysis
Project Objective
To design a system of stormwater improvements
that will mitigate local flooding in the area generally
from Shields Street on the west, to Olive on the
' North, to Mulberry on the south, and to Remington
on the east. In addition, to provide for adequate
water quality treatment of the 80'h percentile flows
before discharging into the Poudre River. Finally, to
accomplish these goals while balancing the social,
economic, and environmental considerations of the
project.
iGeneral
Ayres Associates (Ayres) will provide services as
required to complete the Alternative Analysis of the
Magnolia Street Stormwater Outfall Project. The goal
of this first phase of work will be to complete an
Alternative Analysis and select a preferred design
for some combination of street flow, channel flow,
storm sewer, and inlets for flood mitigation. In
addition, Ayres will look at opportunities for providing
' localized water quality treatment along the project
corridor in addition to the use of the Udall water
quality pond at the downstream end. The Alternative
Analysis will be completed using the Alternative
Product Delivery System (APDS), with the goal of
determining the design configuration that most
effectively accomplishes the project objectives while
' minimizing cost and environmental and construction
impacts. The following are Ayres' contacts for the
project:

The fee shown under Phase I -Tasks 1.9 and
Phase II -Task 3.2 has been provided by
Lyman -Henn based on their understanding of
the project.
Task 2 — Alternative Analysis
2.1 Identification of Alternative Design
Improvements. Ayres and the rest of the
APDS team will use the proposed Master
Plan solution as a foundation, or starting
point, for the final selected alternative. As
with previous projects, the group will be
assimilating a lot of information about the
project corridor in terms of utility conflicts,
physical design constraints having to do with
the pipe profile, geotechnical issues,
groundwater concerns, constructability
issues, impacts to the adjacent property
owners, coordination with the railroad, and
issues related to the outfall at the Poudre
River, to name just a few.
owing the review of the Old Town Basin
Master Plan, the selected plan
improvements, and all the data collected as
part of Task 1, Ayres and the APDS team will
identify possible alternative solutions. As
each alternative is examined, its feasibility
will be addressed in terms of constructability,
benefits, environmental impacts, utility
conflicts, and cost. Note: The fee shown
under Phase I Task 1.8 and Phase II Task
1.4 has been provided by CTL Thompson
based on their understanding of the project.
.
Hydrologic Analysis. Ayres shall conduct
supplemental detailed hydrologic analysis
necessary to support the alternative analysis
and future Detailed Preliminary Design.
Modifications of the Master Plan ModSWMM
model may be necessary to determine flow
rates for storm sewer trunk lines, laterals, and
inlets. Additional detailed basin delineation
may be necessary to provide detailed design
point information along the project corridor.
The hydrologic analysis shall include the 2-,
10-, and 100-year storm events.
2.3 Hydraulic Analysis. Ayres shall evaluate the
proposed storm sewer/channel/street flow
hydraulics. All analyses will be for the three
flow events determined in Task 2.2. The
current Master Plan analysis for the Magnolia
corridor has been done with HEC-RAS.
Because the ultimate design solution will
probably be some sort of combination of
street flow and pipe system, Ayres will be
using EPA SWMM 5.0.008 to analyze the
different alternatives. Key design points from
the Master Plan models (MODSWMM and
HEC-RAS) will be checked against the
results of the SWMM 5.0 modeling. Ayres will
update the Master Plan ModSWMM model at
the end of the alternative analysis phase.
2.4 Evaluation of alternatives. This scope
assumes that up to three alternative designs
will be identified and evaluated to a level of
detail that will support preliminary
construction cost estimation. The three
alternatives will be compared against the
Master Plan alternative. The level of design
needed to evaluate the alternatives will be
dictated by the APDS team but will likely
include plan and profile sheets, including
utility locations; soil boring information; inlet
types; sizes and quantities; and hydraulic
structure details.
2.5 Evaluate alternatives for localized water
quality treatment. The APDS team will
investigate opportunities for providing
additional water quality treatment either
through the use of bio-swales, bio-boxes,
pervious pavement etc., along the project
corridor.
2.6 Prepare quantity estimates for
construction estimating. Ayres will prepare
quantity take -offs for the alternatives for

inform and educate the public about the
project and to obtain feedback. Ayres will
provide exhibits for the open house including
existing and proposed project floodplain

attendance to address questions or
concerns. In addition, the scope assumes
that two to three smaller scale open houses
will occur during the course of design.
1.9 Council work session. The scope assumes 2.3
that Ayres will prepare for and attend at least
one Fort Collins City Council work session on
the project. Ayres will assist by gathering
data, preparing exhibits and contributing
slides to the power point presentation.
Task 2 — Analysis and Design
2.1 Field Investigation. During the Detailed
Preliminary Design, Ayres anticipates several
field trips to the project site. City staff, the
City's contractor, and other members of the
project team may also need to be present to
discuss site specific issues and determine the
best course of action.
2.2 Hydrologic Analysis. Ayres shall conduct
supplemental detailed hydrologic analysis
necessary to support the Detailed Preliminary
Design. Modifications of the Master Plan
ModSWMM model may be necessary to
determine flow rates for storm sewer trunk
lines, channels, laterals, and inlets. Additional
detailed basin delineation may be necessary
to provide detailed design point information
along the project corridor. The hydrologic
analysis shall include the 2-, 10-, and 100-
year storm events. Ayres will provide three
ModSWMM models as part of their design
report including:
• A copy of the current existing condition
ModSWMM model
• The Proposed Project ModSWMM
model that will include any adjustments
made to the existing condition model to
reflect the Detailed Preliminary Design
of the Magnolia Street Stormwater
Outfall Project
• The updated Master Plan ModSWMM
model which will include any
adjustments made to reflect the Detailed
Preliminary Design of the Magnolia
Street Stormwater Outfall Project
Ayres intends to use EPA SWMM 5.0 to
model the hydraulics of the system, as stated
in Phase I Task 2.2. Therefore, the proposed
project condition ModSWMM model and
Master Plan ModSWMM model will reflect the
results obtained with EPA SWMM 5.0. This
will be accomplished by adjusting model
connectivity and any detention volumes to
force ModSWMM to reflect the results found
in EPA SWMM.
Hydraulic Analysis and Design. Ayres shall
analyze the proposed storm sewer hydraulics
for the three flow events listed in Task 2.1.
Ayres will be using EPA SWMM 5.0 to
analyze the storm drainage system. Inlet
design shall be performed using UDINLET.
Street capacity calculations shall be based
on standard City of Fort Collins drainage
criteria. The current floodplain modeling has
been done with HEC-RAS. Any residual
floodplain modeling that is required will also
be done with HEC-RAS. It should be noted
that for the Old Town Basin, floodplains are
defined for areas where street flows generally
exceed 200 cfs. Once the Old Town Basin
selected Plan of Improvements is
constructed, the mapped floodplain areas
would generally be reduced to below 200 cfs.
Ayres will determine what, if any, residual
floodplain would remain along the project
corridor once the Magnolia Street Outfall
Improvements are completed, and City staff
can provide direction as to revising the
regulatory floodplain maps at that point.
2.4 Design of Energy Dissipation Structure at
Outfall to Poudre River. Ayres will develop
alternatives for the downstream energy
dissipation system and present them to the
APDS team. Possible options include a major

Experience with APDS
Ayres Associates is well versed in the City's
' Alternative Product Delivery System (APDS) through
its past and current work with the City of Fort Collins.
We understand that this open design process
' combines the expertise and input from the owner,
engineer, and contractor on a regular basis,
beginning with the preliminary design and carrying
through to the end of construction. Our experience
' with APDS has shown that it reduces the design and
construction cost, produces a better design, reduces
conflict between the parties by greatly improving
' communication, eliminates construction claims, and
shortens the project schedule.
Almost all engineers have had exposure to the more
' traditional partnering processes. However, with
these types of arrangements, the contractor and
engineer work independently with limited
' communication. Involving the contractor during the
design phase greatly reduces the possible
misinterpretation of the requirements of the
' construction documents and allows the contractor to
provide valuable insight into possible construction
issues, constructability of the various project
components, physical costs, and the overall project
schedule. Unknowns and associated increases in
construction costs (e.g. additive change orders) are
virtually eliminated. Involving the engineer through
' the construction phase produces a more efficient
solution to any construction issues and eliminates
conflict between the engineer and contractor. In
' general, designing and constructing a project with
the APDS process generates complete
understanding of and ownership in the project
design.
' Project Team Members' Experience
with APDS
' Andrea Faucett of our team has considerable
experience working with the Fort Collins APDS
process. Her first exposure to APDS was on the
Locust Street Outfall project, where she was project
engineer. Ms. Faucett then completed the design of
the Sheldon Lake project under APDS. Both projects
were complex from a modeling, design, and
construction standpoint and both had extremely
successful outcomes due to the APDS process.
Most recently, Ms. Faucett, Jaclyn Michaelsen, and
TC Bohnet have worked on the design and
construction of the Canal Importation Ponds and
Outfall (CIPO) project. One unique feature of that
project is that Ayres Associates staff worked closely
and extremely well with another firm, Anderson
Consulting Engineers (ACE), who would normally be
considered a competitor. Our collaborative efforts on
CIPO worked extremely well, and both firms
continue to seek help and insight from the other on
projects outside of CIPO.
Ms. Faucett, Ms. Michaelsen, and Linsey Chalfant
have also recently completed the final design for the
North East College Corridor Outfall (NECCO) Project
using APDS. Although the NECCO project has not
yet been constructed, the City's APDS contractor
was instrumental in providing feedback and
suggestions on improvements to the design.
Chris Pletcher also has experience with the APDS
through his work on the C&S Pond and BNRR
Railroad Embankment projects and most recently
with the Pleasant Valley Pipeline Screen. This
particular project showcased how quickly and
effectively a critical problem could be solved using
the APDS. The APDS team, including staff from
Ayres Associates and Hydro Construction, devised
an innovative application of technology that was
energy efficient and had minimal by-products for
disposal.
Projects we have completed or are currently
underway that use the APDS process include:
• Canal Importation Ponds and Outfall Design
(CIPO)
• Northeast College Corridor Outfall Design
(NECCO)
• Pleasant Valley Pipeline Screen
• Spring Creek Pre -Disaster Mitigation, C&S
Pond and BNRR Sites, Ft. Collins, Colorado
• Wastewater Infiltration and Inflow Reduction
and Hydraulic Model Update
• Water system hydraulic model update and
water quality scenario modeling

Re: Proposal No. 7084
Dear Dean:
Ayres Associates is pleased to present this proposal to provide a detailed preliminary design of
the Magnolia Street Stormwater Outfall Project along with possible future design services for
water, wastewater, and stormwater capital projects. The City of Fort Collins is, and has been, a
very important client to our office for many years, both in terms of the relationships that we have
developed and the work that we have completed for the City. Our staff is a part of the Fort
Collins community, and as such we feel a tremendous personal investment with the work that
we do for the City. We are in fact one of the largest civil engineering firms in Fort Collins.
Our project team has significant experience with the City's APDS design process, including
large and small projects and projects that have been submitted for awards and written up in
trade journals. That experience includes the Locust Street Outfall design, Sheldon Lake, the
Drake Relief sewer, the C&S pond, and the more recent CIPO project. In addition we have
recently expanded our services with the City to include sewer flow studies, water distribution
modeling, and I & I studies. We have been helping with the Halligan Reservoir enlargement
project for many years.
In particular, Ayres Associates provides the following key benefits:
• Years of successful completion of a large number of technically challenging projects in
areas including storm drainage, water, and wastewater
• A staff well versed in the APDS process and ready to adapt with the City to new project
objectives and decision making criteria, including Triple Bottom Line and environmental
sustainability
• Detailed knowledge and experience with the City of Fort Collins design process, criteria,
and staff
We realize how important it is to the City to acquire services of highly qualified and responsive
consultants. We are committed to providing the City with the services of an exceptionally well -
qualified team that will ensure the continued success of the City's water, wastewater, and storm
drainage. utilities. Thank you for the opportunity to present our qualifications for this exciting
project. We look forward to continuing our relationship with City staff. If you have any questions,
please contact us at 970.223.5556.
Sincerely,
Ayres Associates

RE: Reference
To Whom It May Concern:
' This letter is intended for potential clients of Ayres Associates from the Fort Collins, CO
office. I have worked closely with Dr. Jim Schall and his staff in Fort Collins for over 2
years. Projects have ranged from large scale water storage projects to technical design
work for our Fort Collins Water Treatment Facility.
Fort Collins Utilities requires a number of engineering services for their water resource
' and treatment operations. Our work has involved internal and external stakeholders,
federal and state agencies, and rigorous project deadlines. My interaction and project
experience with Ayres Associates is nothing less than outstanding and the staff from
Ayres has met the challenge of each one of our projects.
I would recommend Ayres Associates for any project that a potential client may have
knowing that the staff is highly motivated, has tremendous expertise in solving water
' related projects, listens carefully to the client, and completes the work on time and within
budget. In today's challenges with tight budgets, doing more with less, and the need to
solve complex problems, Ayres delivers.

Our experience with water and wastewater analysis
has grown in the past three years with the expertise
of Chris Pletcher. Mr. Pletcher was one of the
original authors of the Fort Collins sewer hydraulic
model and has been working with the City to use
that model and current flow monitoring data to track
infiltration and inflow into the sanitary sewer
collection system. In addition, Mr. Pletcher and his
staff are constructing a similar sewer hydraulic
model for the City of Loveland, including use of the
model to document the condition of the system in a
utility plan update and identifying needed capital
projects for ongoing operation of the collection
system. Over the past year, he has also been a
team member with City staff Sue Paquette and Judy
Billica in a working group to update the water
distribution system model for use in operational and
emergency scenario evaluation. His background in
closed conduit hydraulics has helped correct several
misrepresentations of City tanks and pump stations
so the model reflects the reality of the existing
system and operational control strategies used by
the water plant.
We conduct our hydraulic modeling data collection
effort with in-house staff trained in confined space
entry and job -specific safety practices and have
trained City staff to be a part of our confined space
entry team, allowing us to be more efficient when
City staff are available. Supporting our analysis
expertise, Ayres Associates offers structural design,
complete survey and mapping capability with Fort
Collins -based field crews, and construction
management services.
Successful storm drainage design invariably
involves utility conflicts. Ayres Associates has
considerable experience with capital improvement
projects and new development where water, sanitary
sewer, and other utilities have been relocated or
newly designed; many of these projects have been
with the City of Fort Collins. Experience includes
completing several large-scale projects in highly
urbanized settings where numerous utilities are
highly congested. Projects such as the Canal
Importation Ponds and Outfall Project (CIPO) and
the Washington Avenue Outfall contained an array
of utilities such as water, sanitary sewer, gas, and
fiber optic duct banks. These situations had to be
resolved with creative, cost-effective solutions during
the design phase and during construction when
unknown utilities were discovered.
Whether a project requires new design or improving
an existing system, Ayres Associates has the
experience and capabilities to produce innovative
and effective solutions to utility design problems.
Ayres Associates' survey department has extensive
experience in northern Colorado. In addition to many
construction staking projects, the survey department
completed the aerial mapping of the Big Thompson
floodplain and topographic surveys of the
Washington Avenue Outfall in Loveland. For more
than 12 years, we have worked with Poudre Valley
REA on locating existing rights -of -way and
easements, along with writing legal descriptions for
new easements.
If needed, support in other specialty areas for future
capital improvement projects, such as water and
wastewater treatment plant design, detailed
structural design, bridge design, dam and reservoir
rehabilitation and design, and underwater inspection
can be provided by technical staff from other Ayres
Associates offices. Our offices are linked by a
high-speed intranet and state-of-the-art
videoconferencing. We recently provided a dam
safety inspection (dam and valve shaft), underwater
inspection of the outlet works, and structural design
of outlet tower improvements (part of our Rosemont
dam/pipeline project) using staff from another office.
We also completed the design of the round Bureau
of Reclamation energy dissipation structure for the
CIPO project using structural design support from a
different Ayres Associates office.
Our team has extensive computer aided drafting and
design (CADD) and GIS capabilities. Design work is
accomplished using either MicroStation or AutoCAD
platforms depending on our client's preference. Our
staff is experienced in the latest ArcGIS (version
9.3). Ayres Associates' staff has a range of expertise
in GIS design, population, attribution, and analytic
modeling. Our GIS experts have experience in
designing databases and preparing high -quality,
readable maps. We are experienced in computer
mapping, image processing, registration and data
conversion techniques, database development,
physical and logical database design, statistical
analysis, interpretation, and presentation.

' Ayres Associates Team
Resources
Within the proposed Ayres Associates team, we
bring specific expertise to the City in terms of all
areas of water resource design, engineering
analysis, utility operation and optimization,
construction management, regulatory review,
permitting, and training. The organizational chart
following in this section illustrates the general Ayres
Associates capabilities that are available to the City
through our firm and our contractual partners.
We have partnered with two subconsultants for
environmental support — Cedar Creek Associates
(Steve Long and Mike Phelan) and Alpine Ecological
Resources (Andy Herb). These two firms have
similar capabilities but bring unique perspectives to
environmental issues and mitigation. In addition, we
believe that additional support for environmental
issues may be helpful as the City refocuses priorities
for projects, which may lead to more environmental
mitigation or restoration projects.
We have also partnered with two geotechnical
subconsultants — CTLIThompson and Lyman -Henn
Inc. CTLIThompson is already under contract to the
' City, but we believed it was important to include the
firm's expertise in local soil conditions and soil
issues related to conventional construction. Lyman -
Henn adds to the experience of CTLIThompson with
specialized tunneling and trenchless construction
design experience. The Magnolia Street Outfall will
likely include tunneling at Riverside Drive and
potentially at College Avenue and Mason. In
addition, future projects may include trenchless
construction methods, which provide a tangible
benefit to City residents in reduced disruption to
existing neighborhoods due to major project
construction. Lyman -Henn has the experience to
know what techniques of trenchless construction are
appropriate for different situations and how to
mitigate the risks of working underground without
being able to see adjacent utilities or obstacles.
Selected Resources for
Specific Projects
We anticipate that the Magnolia Street Outfall will be
led by project manager Andrea Faucett based on
her experience with the Locust Street Outfall,
Sheldon Lake, and CIPO, three similar large -pipe
projects through existing streets and neighborhoods.
Survey manager Brian Nelson, survey crews, and an
in-house aerial photogrammetry team will support
Ms. Faucett, along with staff engineers Jaclyn
Michaelsen and Linsey Chalfant for utility data
collection, stormwater design, stormwater quality,
and utility relocation coordination and TC Bohnet for
construction management.
In addition to the Magnolia Street Outfall, we
anticipate continued support of the City with
updating and use of the wastewater collection
system hydraulic model and the water distribution
system model. Our wastewater work includes flow
monitor installation with confined space entry
procedures, data processing, and recommending
techniques to reduce extraneous flow into the
wastewater system. Eliminating clear water
infiltration and inflow to the wastewater system
extends the functional capacity of the City's water
reclamation facilities and reduces overall cost to the
City. Our work with the water system model includes
technical support and modeling expertise to
supplement the City's staff as various operational
and emergency scenarios are modeled. We hope
the City will continue this effort to increase the
efficiency of its utility operations in 2010 and
beyond. This work is led by project manager Chris
Pletcher, with support.from Sam Lowe, Katie
Rubush, and other staff as needed to meet our
safety requirements for confined space entry.
For other projects that may come up during the term
of this contract, we will assemble a team of
experienced professionals and present their
background to the City as the project team is
assembled. We can also pull in our subconsultants
or other community partners as needed to address
nearly any utility -related issue the City may have.
