Sanitary Sewer Master Plan
1.0 PROJECT SUMMARY
1.1 Project Manager Overview
This update of the Sanitary Sewer Master Plan 2009 indicates that the sanitary systems current
capacity meets most of the needs of development and redevelopment in Denver. This update shows
fewer pipes to monitor for limited capacity. Approximately 3% of the pipe network needs to be
monitored for capacity issues, down from 9% in the 2006 Plan. The cost estimate to replace identified
pipes was reduced to roughly $72 million, down from $182 million in the 2006 Plan. The results of the
Capacity Model are available, in paper and GIS format, for staff reference to support both land
development review and maintenance operations.
Three significant updates were made to improve on the 2006 Sanitary Sewer Master Plan:
1. The Sanitary Sewer Design Technical Manual was updated in March of 2008. The formula used
to calculate the flow in a pipe has been reduced based on over 20 years of pipe metering data.
John Gaines, of Denver Wastewater Management Division, reviewed the historic record of
sanitary flow metering and recalculated the peaking factor for the flow formula. Land use
loading factors have also been revised to more closely match the 2000 Census data for residential
household size and water consumption information from billing records in 2000. The new
criterion was used in this Master Plan.
2. The Capacity Model was reprogrammed to run in Environmental Systems Research Institutes
(ESRI) ArcGIS Geographic Information System (GIS) program. In 2006, it took staff three
weeks to run the Model, in two programs, requiring import and export of data. The lessons
learned in the first modeling effort were used to program the GIS based Model to run in less than
an hour for the study area. GIS tools were developed to evaluate development impacts on a
planning level review. These tools also allow for long term updates to land use and the sanitary
network to provide concept level calculations for improvements.
3. The sanitary network was updated to support many new requirements of the Capacity Model.
The support and improvement of the data has been an integral part of the modeling process. Data
improvement has made it possible to update this Master Plan and will lend value to future
efforts. Paul Tessar, Rick Stretz, and Dan Houser, of Denver GIS, supported the data
improvement for the Master Plan.
This planning effort reiterates the need to focus on the condition of our sanitary network. The
documentation of the current television inspection program, and on-going maintenance efforts, will
prove valuable in ranking the system condition.
The Wastewater Management Division staff has provided a plan to meet future sanitary system service
needs for over a century. Sanitary system capacity still will need to be monitored and managed based on
the development changes that take place in the future. This Master Plan provides the way to continue
monitoring capacity needs.
October 2009
This project was a team effort, accomplishing much with the experience and vision of all. My thanks go
out to the staff that helped to accomplish this Master Plan. Our next focus will be to review and assess
wastewater collection system condition.

1.2 Executive Summary
The City & County of Denver currently operates and maintains just under 7.8 million lineal feet of
active, existing public sanitary sewer system within their jurisdiction. This does not include the roughly
875,000 feet of pipe owned and maintained by the Metro Wastewater Reclamation District (Metro), or
the roughly 1.3 million feet of privately owned and maintained pipe within the City. This Sanitary Sewer
Master Plan serves as the framework for management of sanitary sewer capital improvements within the
City & County of Denver. The Master Plan has been prepared to provide new information, available via
GIS, about the adequacy of the Citys sanitary sewer infrastructure to accommodate future growth based
upon land use. This update process includes the 155 square miles of the City & County of Denver, with
special focus on areas experiencing major redevelopment. This Master Plan provides an overview
evaluation of loading and hydraulic conditions, and identifies areas of possible deficiency and associated
capital improvements that may be needed within the City.
The sanitary sewer collector system has increasingly become a critical infrastructure element for capital
improvement planning as growth and major redevelopment occurs across the City. The completion of
the Denver Land Use and Transportation study resulted in the formulation of Blueprint Denver: An
Integrated Land Use and Transportation Plan, which ostensibly prepares the City for continued
urbanization and redevelopment. One of the major goals of this updated plan is the integration of master
plan documents and programs into a comprehensive Public Works Management Program.
This Master Plan looks ahead to year 2050 at growth areas and areas with significant changes in land use
densities to determine that 201,074 lineal feet of the Citys sanitary sewer system may be capacity
limited in the foreseeable future. This will result in ongoing monitoring for approximately 2.6% of the
existing City owned and maintained sanitary sewer lines for capacity related issues. Further study and
monitoring of these capacity limited reaches will be necessary to determine actual infrastructure needs.
A total of approximately $72 million in capital improvements has been identified for sanitary sewer
upsizing based upon capacity constraints for the projected Blueprint Denver land use. This cost
projection equates to an average of $358 per lineal foot total cost for upsizing existing sanitary sewer
systems. This includes manholes, pavement patching, incidentals, administrative, and contingency costs.
The next step, beyond this Master Plan, will be continued system monitoring by metering and
prioritizing improvements to address capacity deficiencies. Pipe condition will be documented by
television inspection and will be included in the prioritization process.

1.3 Goals of the Sanitary Sewer Master Plan
To provide direction to the planning process and capitalize on the extensive experience and knowledge
of staff, selected members of the City Public Works and Planning Departments were interviewed. The
following questions were posed to these stakeholders:
What are the Primary Sanitary Sewer Issues Confronting the City?
As the City is developed to the allowable land use, some of the sanitary sewer system will not
meet current criteria, whereby the pipes are flowing no more than 80% depth (approximately
86% of the sewers full flow capacity) in a peak event. In other words, pipes are sized in the
Master Plan to provide for theoretical capacity for flows based upon maximum probable land use
zoning.
The existing sanitary infrastructure is aging and maintenance is required. Some segments are
over 100 years old. It is necessary to replace or rehabilitate many reaches of pipe each year to
reduce infiltration and inflow and improve the integrity of the pipe.
The Master Plan needs to address the implications of redevelopment. Major projects, such as
Stapleton and Lowry, benefited from scale economics and private-sector developer investments
to construct new collectors and outfalls. Smaller redevelopment projects, such as those within
Lower Downtown, may lack the financing and cohesion to build completely new systems.
What Approach Should be Followed to Provide an Upgraded Sanitary Sewer System?
Ensure compatibility with Blueprint Denver
Ensure compatibility with current land uses and needs
Support, and be compatible with, the current Capital Improvement Program for sanitary and
other Public Works programs like the Environmental Management System and Greenprint
Denver
Encourage and enable development participation
Provide phasing and priorities for capital improvements
Minimize construction impacts to already developed properties
Provide a document that is rational and likely to foster support for capital improvements
Minimize Costs
What are the Goals for the Master Plan Update Process?
Provide a framework document that informs staff of potential deficiencies
Create optimal value with the Master Plan to capitalize on available revenues, while providing
the greatest level of service
Ensure that facilities are designed as required by criteria, and that a commensurate budget for
new capital improvements is anticipated and budgeted
Provide a toolbox for reviewing development proposals, including access to background
information used in the plan and models that may be modified by staff as more specific
development proposals are submitted
Provide a framework for continued urbanization of the City & County of Denver and implement
the concepts and tenets of Blueprint Denver
October 2009
What Challenses Would Prevent Denver From Obtainins This Goal?
Modeling should be developed in sufficient detail to support the conceptual design and sizing of
infrastructure. The Master Plan proposed improvements will be used to identify possible
deficiencies and establish budgets for capital improvements. The current alignment of the system
will be used to calculate the additional capacity needed in future build-out conditions. This
concept level calculation will be used to estimate cost of improvements for deficient pipes.
What is an Appropriate Measure of Success for the Update Process?
Completion of the Master Plan with enough detail to validate or justify modification of the Citys
current Capital Improvement Program
Establishment of a framework for screening options and supporting a preferred plan for
implementation
Creation of a document that is usable and provides for continued update by the City
1.4 Objectives of the Sanitary Sewer Master Plan
The Master Plan helps to determine wastewater collection system needs and guide capital improvements
through 2050. It is a living document that undergoes modification utilizing the Citys GIS data and
modeling methods to update planning information, collection system configuration, and the Capital
Improvement Program. The Master Plan GIS Tools allow the City staff to analyze what-if scenarios to
predict sanitary sewer system impacts from changes in land use, timing of development, wastewater
flow criteria, and other factors.
2.0 BACKGROUND
2.1 History of Master Planning
According to Denvers 1950 Sanitary Sewer Master Plan, Denver has provided sanitary system
improvements for over 100 years. It states, The first public agitation for improved sanitary facilities
came between 1870 and 1880 when large population increases produced acute sanitary problems. The
1917 annual report of the Department of Improvements and Parks contains the following account:
December 9, 1875, a committee, after considerable agitation in the City, reported a sewage
system as impractical for the City.
There was a little agitation now and then until May 2, 1878, when a committee reported
adversely on sewerage, but recommended individual drain pipes, adding that if the people wanted
to vote bonds for a system they would be allowed to do so. It was urged that the system would
cost $37,000, and the City had no money.
December 5, 1878, sewer agitation continuing, a committee that had been sent to St. Louis
reported on a sewage system with 24-inch pipe in Wazee Street and 15-inch pipe in Fifteenth,
Seventeenth, and Nineteenth Streets from Curtis to Wazee, to cost $28,000 that would drain that
portion of the City for all future time.

Sanitary Sewer Master Plan
In 1879 the agitation continued and a sewer district embraced by Delgany Street, Broadway,
West Colfax, and Twentieth Street was urged, but again it was declared the city had no money,
and the people were adverse to voting bonds. In 1880, the agitation continued, and in 1881 the
first sanitary sewer was built, being 4,620feet in length and costing $24,192.16.
The 1950 Master Plan goes on to state, From this meager beginning 70 years ago, the sanitary sewer
system has grown to the present extensive network. The rate of growth has varied with the times. During
years of war or depression few, if any, new sewers were constructed. On the other hand, during periods
of prosperity it has sometimes been difficult to expand the system rapidly enough to keep pace with the
growth of the City. In 1950, there were over 800 miles of lateral and main sanitary sewers contributing
flow to two sewage treatment plants. The 2008 GIS figures indicate just under 1,900 miles of sanitary
sewers in the City & County of Denver, and the flow is treated at the Metro Districts Robert W. Hite
Metro Treatment Facility in northeast Denver.
The 1950 Master Plan showed vision and foresight for sanitary master planning. According to the
Master Plan, The sanitary sewer system was under the direct supervision of the late Mr. Charles A.
Davis, City Sanitary Engineer, from 1913 to 1951. Much of the present system and both treatment plants
were constructed during this period. From the facts presented in the remaining part of the report, it will
be apparent that the policies followed in the design and construction of sanitary sewers have been sound
and farsighted. The citizens of Denver should be proud of their sanitary sewer system and of the men
responsible for its development.
Master planning efforts in the 1970s and 1980s identified system needs that were improved by capital
projects. The 2009 Master Plan serves as an update to the first GIS based Master Plan completed in
2006.
2.2 Population Forecasting
When the 1950 Master Plan was completed, the population of Denver was 415,786. At the time, this was
a major increase of 29 percent over 1940 and was the largest percentage increase for any 10 year period
since 1910, which prompted the need for infrastructure master planning to serve the growing population.
The 1950 Master Plan anticipated a population in 1970 of 560,000 (actual was 514,678). Figure 2.1
summarizes data provided by the Denver Office of Information Technology, and depicts the population
of Denver by 10 year increments from 1870 through 2000. The July 2009 population estimate, according
to the Denver Business Journal, is 598,707. Although mostly built-out, the population is expected to
continue to increase with higher development densities. By the year 2035, the Denver Regional Council
of Governments forecasts a population of 762,612. Figure 2.1 illustrates this change in population from
1870 to 2035.

3.1 Methodology
Figure 3.1 illustrates the process flow followed to complete the modeling portion of this Master Plan.
FIGURE 3.1 PROCESS FLOW
Page 5


Sanitary Sewer Master Plan
GIS data for the sanitary sewer network and land use were evaluated for inaccuracies. The land use data
were processed for current and future loading to the sanitary system on the parcel level. Each parcels
flow was assigned to a sanitary pipe. A Capacity Model accumulated the flow from each parcel
downstream in the sanitary network. The flow was peaked and took into account infiltration and inflow.
Pipe flows were compared against pipe capacities for possible capacity deficiencies. Capacity deficient
pipes were assigned a cost for improvement based on historical bid data.
Basins were delineated based on logical groupings of pipe.
3.2 GIS Data Quality Control
The Citys comprehensive GIS database was used heavily in this Master Plan study to evaluate land use
and existing pipe networks. The data were reviewed and corrected based on the best available
information and staff knowledge. Special data management tools were developed that assisted Master
Plan users in viewing and modifying GIS data. Capacity Model data input and output were incorporated
into the GIS database to determine capacity limitations of the existing system and to propose sanitary
infrastructure improvements.
3.3 Land Use Analysis
Blueprint Denver is an essential framework document that establishes the basis for future land use
planning, advocating that land use and transportation decisions be made in conjunction. To assist with
future planning, Areas of Change and Areas of Stability are delineated in Blueprint Denver. Areas of
Change depict expected development areas based on a 2050 build-out condition. The Areas of Change
data are included with the Master Plan mapping, for reference, to show the potential changing land use,
and to highlight the areas where capital investment in infrastructure may be needed.
Denvers Sanitary Sewer Design Technical Manual underwent a revision in March of 2008 to update
policies, methods, practices, procedures, and design standards utilized in the Department of Public
Works activities. The intended purpose of the document is to provide guidelines for the design of
sanitary sewers, thereby encouraging consistency. Loading factors have been updated to the 2008
criteria. These better suit the average metered flows observed in each zone district based on population
density analysis. 2020 land use categories were then matched to their zone district counterpart to
determine their flow factors.
The Citys GIS parcel and Blueprint Denver concept land use data were used to establish sanitary sewer
loading. The Capacity Model can incorporate updates to land plans and growth rates, including the
incorporation of future GIS data and graphical user interfaces.
Loading factors are based on the propertys land use/zoning. System capacity loading was computed by
linking land use with loading factors as shown in Table 3.1. For this study, two primary land use
scenarios have been utilized: Year 2009 and Year 2020 from Blueprint Denver. The Capacity Model
applies the appropriate loading factors to the land uses.
In this 2009 update to the Master Plan, demographic information was used to test existing and future
land use assumptions. Population and employment data were obtained from the Denver Regional
Council of Governments for the years 2005, 2015, and 2030. Areas of the City were divided into Traffic
October 2009
Analysis Zones. Analyses were completed, on the subbasin level, to compare predicted sanitary flow
from the demographic data to the predicted flow for the land use data. A future, more refined, study will
need to be conducted to thoroughly validate the land use assumptions against the demographic
information.
Hydraulic modeling was completed to compare existing hydraulic capacity with anticipated future
flows. Flow projections for the Master Plan are based on the current zoned land use designation and
Blueprint Denver, modified, as necessary, to better reflect the anticipated development of any particular
parcel. The overall planning criteria for the City & County of Denver is to attempt to provide sewerage
capacity to accommodate the current zoned land use or future predicted land use, not necessarily the
actual existing land use. Therefore, Model data showing sanitary sewer lines unable to convey future
flows may be functioning well within capacity today. However, if the entire tributary basin were built to
zoned land use, there likely may be capacity deficiencies. The next step, beyond the Master Plan, is to
field verify capacity-limited reaches by monitoring flows in the pipe before programming and designing
improvements.
Flow projections, using these planning criteria, likely result in flows that are different from the flows
currently conveyed in the existing system. Parcels may not currently be built to their full land use
densities. Therefore, the flows projected in this Master Plan may not be appropriate for final design. If
the difference in flows between the current land use and zoned/future land use is significant, replacing
an existing pipeline, with a significantly larger diameter pipeline, could result in low depths that may
contribute to depositional problems as well as possible hydrogen sulfide issues, including odor and
corrosion.

3.4 Hydraulic Loading
Flow from all parcels was loaded to pipes based on proximity and knowledge of how the flow connects
into the system. Spider lines were used to graphically represent the connection of a parcel to a pipe.
Spider lines, in red, are illustrated in Figure 3.2.
FIGURE 3.2 SPIDER LINES
3.5 Mannings Peaking Factors
To determine the adequacy of the sanitary sewer pipes to convey the flow, a peaking factor is generally
applied per the Sanitary Sewer Design Technical Manual. The peaking factors are based upon average
daily flow rates. As the sanitary basins become larger, the peaking factor decreases. During the 2006
effort, the equation used was: peaking factor = 3.8 x (ADF)'0'17; where ADF is the Average Daily Flow
in cubic feet per second with the peaking factor capped at 5.0. The 2009 effort caps the peaking factor at
4.0 and uses the equation: peaking factor = 2.6 x (ADF)'0'16. The Denver Wastewater Metering Program
records, for over 20 years, were used to determine the change in the peaking factor equation. This study
was the basis for changing the design criteria.
3.6 Capacity Modeling
The Capacity Model approach was used throughout the City to simulate the operation of the City owned
and maintained sanitary sewer collection system for the sanitary basins under current (2009) and future
(2015, 2020, 2030 and 2050) scenarios. The Model is based on the assumption that flow is steady
through time. The goal is to predict the maximum flow that could be possible and plan to meet those
October 2009
conditions. The systems ability to convey wastewater loads under dry and wet situations was analyzed.
Maximum flow is determined by multiplying the average sewer flow by a peaking factor and adding
infiltration and inflow. This Master Plan used a constant infiltration and inflow rate of 500 gallons per
acre per day for sanitary sewer design. The Model accumulates the flow downstream through the
sanitary sewer pipe network. Reaches of pipes that were at, or near theoretical capacity, were identified
for improvements in this Master Plan. Upsizing of capacity limited pipes was based on Mannings
Equation, which takes into account pipe diameter, slope, and a friction factor. Mannings Equation
relates pipe flow as a function of pipe slope and diameter.
3.7 Deficiencies Based Upon Current Criteria
The Model output was symbolized to identify, by color coding, all pipe sections with surcharging or d/D
(design hydraulic depth to pipe diameter ratio) values at specified levels. This color coding allowed City
staff to identify sections that are nearing or at critical threshold levels. This Master Plan document
utilized the model results to indicate system capacity deficiencies shown herein on basin/subbasin maps.
Pipes in blue will theoretically be operating, based upon allowable land use, at 86% or less hydraulic
capacity. Pipes shown in purple will theoretically be operating above 86% but less than 100% of
hydraulic capacity. Although this may be beyond the criteria of 80% of full flow depth for new pipe, this
shows that the existing system should be capable of handling build-out flows. These pipes may need to
be monitored in the future. Pipes shown in heavy black will theoretically be operating at or over 100%
hydraulic capacity. These pipes could be identified as capital improvements based upon exceedence of
hydraulic capacity. Figure 3.3 depicts a cross section of pipe with these three categorized levels of flow.
Figure 3.4 illustrates a typical pipe reach under study for upgrade.

Sanitary Sewer Master Plan
FIGURE 3.4 TYPICAL PIPE REACH UNDER STUDY
The Proposed Improvements designation identifies the diameter, in inches, in bold, black numbers
along the pipe reach. The pipes capacity shall be such that the sewer is flowing at no more than 80% of
the full depth at the calculated peak flow rate. A depth-variable friction factor shall be used such that the
partial flow rate at 80% depth is approximately 86% of the sewer's full-flow capacity. The peak sewage
flow rate shall be equal to the summation of commercial, industrial, and residential average flows
multiplied by an appropriate peaking factor plus an infiltration and inflow (I&I) allowance.
Required sewer capacity = ((peaking factor x average sewage flow) + I&I) /0.86.
The proposed capital improvements are shown as complete replacement with a circular pipe having
conveyance capacity for the appropriate level of service based upon potential land use. Conflicting
utilities, and other constraints, may necessitate infrastructure equivalents such as parallel pipes. Capital
improvements are based upon the slope of the new pipe matching the slope of the existing pipe.
Shallower slopes, determined during preliminary design, may necessitate larger pipes.
This Master Plan shows the proposed capital improvements as a basis for evaluating sanitary sewer
upgrades by recommending removal of the existing pipe and replacement with the larger new pipe.
Further study will be required to determine specific project scope. Additional study (beyond the scope of
this Master Plan) will evaluate the condition of the existing pipe, calibrate the theoretical flows with
meter flow data, and potentially propose alternative capital improvement projects. Such alternatives
include constructing a parallel pipe, slip-lining the existing pipe, proposing a new pipe alignment, or
accepting existing conditions where flows can be accommodated in a full flow pipe.
October 2009
3.8 Basin Delineations
Basins for the Denver sanitary sewer system were defined, by the existing pipe network, from the point
where they outfall to the Metro sewers. Outfall points to Metro sewers were identified and subbasins
were defined as sanitary sewers tributary to a single Metro interceptor. This was a starting point for
basin delineations which were refined for manageable areas of study, referred to as Map Groups, for
purposes of this Master Plan. Subbasins have been grouped and displayed for map presentation at a 1 =
1,200 foot scale in an 11x17 format. Each map includes general planimetric features, street names,
rights-of-way, existing sanitary sewers with a size designation, pipe material and direction of flow,
legend, and key map.
The Central Business District, of downtown Denver, was the initial focus of the Sanitary Sewer Master
Plan. This basin was selected as a prototype for establishing planning criteria and data management
processes. These protocols were applied to the Citys remaining basins. The next phase of the Master
Plan built upon the initial work by
confirming wastewater flow criteria,
evaluating and improving GIS sanitary sewer network integrity,
applying a Capacity Model approach per the City s Sanitary Sewer Design Technical Manual,
developing a process for assessing sewer system condition and rehabilitation,
and identifying collection system deficiencies for all sewer system basins.
After completion of the Central Business District basin, the Master Plan focused on basins with Areas of
Change as defined by Blueprint Denver. Locations in the Areas of Change include the new growth areas
of Lowry, Stapleton, Gateway, downtown, areas around transit stations, and areas along major streets
and/or transportation corridors. These locations benefit from an infusion of population, economic
activity, and investment. The final effort of this Master Plan analyzed the remainder of the City for
deficiencies, and developed recommended capital improvements for implementation based solely upon
capacity.
3.9 Water Quality Considerations
There is concern that sanitary sewer pipes could experience exfiltration with flow being intercepted by
storm sewers and conveyed to the receiving waterways. The existing GIS network was used to
characterize the interaction between the storm and sanitary sewer systems. The Denver GIS database was
used to determine intersection crossings of storm and sanitary pipes. The greatest concern is intersections
where sanitary pipes may be installed through storm pipes. Secondarily, there are concerns where storm
pipes cross below sanitary pipes. This also applies to areas where the pipes are closely parallel or cross
within 12-inches of each other. Areas where sanitary mains cross under storm pipes are noteworthy, but
less of a direct threat to water quality. The ongoing Storm and Dry Weather Monitoring Program has been
aided by identifying these areas of pipe intersections. Maintenance programs are being developed to
inspect these critical storm/sanitary pipe intersections.

4.0 CAPITAL IMPROVEMENTS PROGRAM
4.1 Cost Modeling
Cost estimating is an important component of the master planning process. Costs have been compiled to
assist in the evaluation of sanitary upgrades, and to provide for systematic capital budgeting for future
improvement programs. Bid data has been obtained, from the City & County of Denver, for the period
1999 to 2005 and reflects typical construction practices within the City. To convert costs to 2008 dollars,
from 2005 dollars, all costs were escalated 7% except for the cost of asphalt patch which was doubled. A
detailed tabulation of all unit costs, and a listing by map group, is shown in the Technical Appendix and
linked to the GIS database for project cost analysis. General unit costs (in 2008 dollars) are summarized
below with sanitary sewer pipe costs charted in Figure 4.1.
Sanitary Sewers:
8 $ 64 per lineal foot
10 $ 67 per lineal foot
12 $ 71 per lineal foot
15 $ 76 per lineal foot
18 $ 81 per lineal foot
21 $ 92 per lineal foot
24 $ 102 per lineal foot
27 through 96 $4.00 per inch diameter per lineal foot
Jack and Bore Pipe: $ 21.40 per inch diameter foot
Manholes: $ 3,040 each Type A (4 diameter pipes $ 4,570 each Type A (5 diameter pipes
Asphalt Patch (assumed 8-ft
wider than the pipe diameter):
Wet Utility Relocation Cost:
Dry Utility Administration Cost:
$ 7,865 each Type B (pipes greater than 42)
Tabulated in GIS and based on replacement of existing
manholes
$ 8.00 per sy-in ($145.46/ton) for
assumed 9-inch full depth section
$3,210 to $21,400 per crossing for storm sewer
$1,070 for relocation/avoidance of water
Wet utility crossings have been tabulated in GIS for each
specific pipe run and are included in the cost model based
upon the size of the conflicting pipe. Costs are for sleeving,
relocation, and protection during construction.
5% of direct construction costs
Removal of existing sanitary sewer pipe has been considered incidental to the new pipe construction and
is included within the new pipe unit costs.
The following index values, from December 2008, can be used for future baseline comparison:
National Urban Consumer Price Index (CPI) = 210.228
Engineering News Record Construction Cost Index (ENR CCI) = 8551
CDOT Construction Cost Index (CDOT CCI) = 330.1
October 2009
Indirect costs have been expressed as a percentage of direct construction costs. These include the
following:

4.2 Summary of Capital Costs
A summary of costs, for all map groups, is presented in Table 4.1 with Figure 4.2 depicting map group
locations. The specific proposed features breakdown, of the cost estimate by map group, is shown on the
adjoining page for every map group. Costs are tabulated programmatically using GIS and are based
upon unit prices developed in 2008.
This Master Plan does not distinguish between developer cost and City cost. In particular, capital
improvements have been shown for new developing areas (i.e., Stapleton). Their funding will be borne
by different entities and budgets when compared to retro-fit improvements of existing development.

Sanitary Sewer Master Plan October 2009 1.0 PROJECT SUMMARY 1.1 Project Manager Overview This update of the Sanitary Sewer Master Plan 2009 indicates that the sanitary systems current capacity meets most of the needs of development and redevelopment in Denver. This update shows fewer pipes to monitor for limited capacity. Approxi mately 3% of the pipe network needs to be monitored for capacity issues, down from 9% in th e 2006 Plan. The cost estimate to replace identified pipes was reduced to roughly $72 million, down from $182 million in the 2006 Pl an. The results of the Capacity Model are available, in paper and GIS format, for staff reference to support both land development review and maintenance operations. Three significant updates were made to im prove on the 2006 Sanitary Sewer Master Plan: 1. The Sanitary Sewer Design Technical Manual was updated in March of 2008. The formula used to calculate the flow in a pipe has been redu ced based on over 20 years of pipe metering data. John Gaines, of Denver Wastewater Management Division, reviewed the historic record of sanitary flow metering and recalculated the peaking factor for the flow formula. Land use loading factors have also been revised to more closely match the 2000 Census data for residential household size and water consumption informa tion from billing records in 2000. The new criterion was used in this Master Plan. 2. The Capacity Model was reprogrammed to run in Environmental Systems Research Institutes (ESRI) ArcGIS Geographic Information System (GIS) program. In 2006, it took staff three weeks to run the Model, in two programs, re quiring import and export of data. The lessons learned in the first modeling effort were used to program the GIS based Model to run in less than an hour for the study area. GIS tools were deve loped to evaluate development impacts on a planning level review. These tools also allow for long term updates to land use and the sanitary network to provide concept level calculations for improvements. 3. The sanitary network was updated to support many new requirements of the Capacity Model. The support and improvement of the data has been an integral part of the modeling process. Data improvement has made it possible to update this Master Plan and will lend value to future efforts. Paul Tessar, Rick Stretz, and Da n Houser, of Denver GIS, supported the data improvement for the Master Plan. This planning effort reiterates the need to focus on the condition of our sanitary network. The documentation of the current television inspection program, and on-going maintenance efforts, will prove valuable in ranking the system condition. The Wastewater Management Division staff has provided a plan to meet future sanitary system service needs for over a century. Sanitary system capacity stil l will need to be monitored and managed based on the development changes that take place in the future This Master Plan provides the way to continue monitoring capacity needs. This project was a team effort, accomplishing much w ith the experience and vision of all. My thanks go out to the staff that helped to accomplish this Master Plan. Our next focus will be to review and assess wastewater collection system condition. Brian Schat, P.E. Project Manager 1.2 Executive Summary The City & County of Denver currently operates an d maintains just under 7.8 million lineal feet of active, existing public sanitary sewer system within th eir jurisdiction. This does not include the roughly 875,000 feet of pipe owned and maintained by the Me tro Wastewater Reclamation District (Metro), or the roughly 1.3 million feet of privately owned and main tained pipe within the City. This Sanitary Sewer Master Plan serves as the framework for management of sanitary sewer capital improvements within the City & County of Denver. The Master Plan has been prepared to provide new information, available via GIS, about the adequacy of the Citys sanitary sewer infrastructure to accommodate future growth based upon land use. This update process incl udes the 155 square miles of the City & County of Denver, with special focus on areas experiencing major redevelopm ent. This Master Plan provides an overview evaluation of loading and hydraulic conditions, and iden tifies areas of possible deficiency and associated capital improvements that may be needed within the City. The sanitary sewer collector syst em has increasingly become a critical infrastruc ture element for capital improvement plann ing as growth and major redevelopment occurs across the City. The completion of the Denver Land Use and Transportation st udy resulted in the formulation of Blueprint Denver: An Integrated Land Use and Transportation Plan which ostensibly prepares the City for continued urbanization and redevelopment. One of the major goals of this updated plan is the integration of master plan documents and programs into a comprehensive Public Works Management Program. This Master Plan looks ahead to year 2050 at growth areas and areas with signif icant changes in land use densities to determine that 201,074 lineal feet of the Citys sanitary sewer system may be capacity limited in the foreseeable future. This will result in ongoing monitoring for approximately 2.6% of the existing City owned and maintained sanitary sewer li nes for capacity related issues. Further study and monitoring of these capacity limited reaches will be necessary to determine actual infrastructure needs. A total of approximately $72 million in capital impr ovements has been identified for sanitary sewer upsizing based upon capacity cons traints for the projected Blueprint Denver land use. This cost projection equates to an average of $358 per lineal foot total cost for upsizing existing sanitary sewer systems. This includes manholes, pavement patching, incidentals, administrative, and contingency costs. The next step, beyond this Master Plan, will be continued system monitoring by metering and prioritizing improvements to address capacity defici encies. Pipe condition will be documented by television inspection and will be incl uded in the prioritization process.

Sanitary Sewer Master Plan October 2009 1.3 Goals of the Sanitary Sewer Master Plan To provide direction to the planning process and capitalize on the extensive experience and knowledge of staff, selected members of the City Public Wo rks and Planning Departments were interviewed. The following questions were posed to these stakeholders: What are the Primary Sanitary Sewer Issues Confronting the City? As the City is developed to the allowable land use, some of the sanitary sewer system will not meet current criteria, whereby the pipes are flowing no more than 80% depth (approximately 86% of the sewers full flow capacity) in a peak event. In other words, pipes are sized in the Master Plan to provide for theoretical capacity for flows based upon maximum probable land use zoning. The existing sanitary infrastructure is aging a nd maintenance is required. Some segments are over 100 years old. It is necessa ry to replace or rehabilitate many reaches of pipe each year to reduce infiltration and inflow and im prove the integrity of the pipe. The Master Plan needs to address the implicatio ns of redevelopment. Major projects, such as Stapleton and Lowry, benefited from scale econo mics and private-sector developer investments to construct new collectors and outfalls. Smaller redevelopment projects, such as those within Lower Downtown, may lack the financing and co hesion to build completely new systems. What Approach Should be Followed to Provid e an Upgraded Sanitary Sewer System? Ensure compatibility with Blueprint Denver Ensure compatibility with current land uses and needs Support, and be compatible with, the current Capital Improvement Program for sanitary and other Public Works programs like the Envir onmental Management System and Greenprint Denver Encourage and enable deve lopment participation Provide phasing and priorities for capital improvements Minimize construction impacts to already developed properties Provide a document that is rational and likely to foster support for capital improvements Minimize Costs What are the Goals for the Master Plan Update Process? Provide a framework document that informs staff of potential deficiencies Create optimal value with the Master Plan to capitalize on available revenues, while providing the greatest level of service Ensure that facilities are designed as required by criteria, and th at a commensurate budget for new capital improvements is anticipated and budgeted Provide a toolbox for reviewing developmen t proposals, including access to background information used in the plan and models that may be modified by staff as more specific development proposals are submitted Provide a framework for continued urbanization of the City & County of Denver and implement the concepts and tenets of Blueprint Denver What Challenges Would Prevent Denver From Obtaining This Goal? Modeling should be developed in su fficient detail to support the co nceptual design and sizing of infrastructure. The Master Plan proposed im provements will be used to identify possible deficiencies and establish budgets for capital im provements. The current alignment of the system will be used to calculate the additional capacity needed in future build-out conditions. This concept level calculation will be used to estimate cost of improvements for deficient pipes. What is an Appropriate Measure of Success for the Update Process? Completion of the Master Plan with enough detail to validate or justify modification of the Citys current Capital Improvement Program Establishment of a framework for screening options and supporting a preferred plan for implementation Creation of a document that is usable and provides for continued update by the City 1.4 Objectives of the Sanitary Sewer Master Plan The Master Plan helps to determine wastewater co llection system needs and guide capital improvements through 2050. It is a living document that underg oes modification utilizing the Citys GIS data and modeling methods to update planning information, collection system configuration, and the Capital Improvement Program. The Master Plan GIS Tools allow the City staff to analy ze what-if scenarios to predict sanitary sewer system impacts from changes in land use, timing of development, wastewater flow criteria, and other factors. 2.0 BACKGROUND 2.1 History of Master Planning According to Denvers 1950 Sanitary Sewer Master Plan, Denver has provided sanitary system improvements for over 100 years. It states, The firs t public agitation for improved sanitary facilities came between 1870 and 1880 when large population in creases produced acute sanitary problems. The 1917 annual report of the Department of Improvements and Parks contains the following account: December 9, 1875, a committee, after considerable agitation in the City, reported a sewage system as impractical for the City. There was a little agitation now and then un til May 2, 1878, when a committee reported adversely on sewerage, but recommended individual dr ain pipes, adding that if the people wanted to vote bonds for a system they would be allowed to do so. It was urged that the system would cost $37,000, and the City had no money. December 5, 1878, sewer agitation continuing, a committee that had been sent to St. Louis reported on a sewage system with 24-inch pipe in Wazee Street and 15-inch pipe in Fifteenth, Seventeenth, and Nineteenth Streets from Curtis to Wazee, to cost $28,000 that would drain that portion of the City for all future time.

Sanitary Sewer Master Plan October 2009 In 1879 the agitation continued and a sewer distri ct embraced by Del gany Street, Broadway, West Colfax, and Twentieth Street was urged, bu t again it was declared the city had no money, and the people were adverse to voting bonds. In 1880, the agitation continued, and in 1881 the first sanitary sewer was built, being 4, 620 feet in length and costing $24,192.16. The 1950 Master Plan goes on to state, From this meager beginning 70 years ago, the sanitary sewer system has grown to the present exte nsive network. The rate of growth has varied with the times. During years of war or depression few, if any, new sewers were constructed. On the other hand, during periods of prosperity it has sometimes been difficult to expand the system rapidly enough to keep pace with the growth of the City. In 1950, ther e were over 800 miles of lateral and main sanitary sewers contributing flow to two sewage treatment plants. The 2008 GIS fi gures indicate just under 1,900 miles of sanitary sewers in the City & County of Denve r, and the flow is treated at the Metro Districts Robert W. Hite Metro Treatment Facility in northeast Denver. The 1950 Master Plan showed vision and foresight for sanitary master plan ning. According to the Master Plan, The sanitary sewer system was under the direct supervision of the late Mr. Charles A. Davis, City Sanitary Engineer, from 1913 to 1951. Much of the present system and both treatment plants were constructed during this period. From the facts pr esented in the remaining part of the report, it will be apparent that the policies followed in the design and construction of sanitary sewers have been sound and farsighted. The citizens of Denver should be pr oud of their sanitary sewer system and of the men responsible for its development. Master planning efforts in the 1970s and 1980s identi fied system needs that were improved by capital projects. The 2009 Master Pl an serves as an update to the first GIS based Master Plan completed in 2006. 2.2 Population Forecasting When the 1950 Master Plan was completed, the popul ation of Denver was 415,786. At the time, this was a major increase of 29 percent over 1940 and was the la rgest percentage increas e for any 10 year period since 1910, which prompted the need for infrastructu re master planning to serve the growing population. The 1950 Master Plan anticipated a population in 1970 of 560,000 ( actual was 514,678). Figure 2.1 summarizes data provided by the Denver Office of Information Technology, and depicts the population of Denver by 10 year increments from 1870 through 2000. The July 2009 population estimate, according to the Denver Business Journal is 598,707. Although mostly built-out, the population is expected to continue to increase with higher development densities. By the y ear 2035, the Denver Regional Council of Governments forecasts a populatio n of 762,612. Figure 2.1 illustrates this change in population from 1870 to 2035.

Sanitary Sewer Master Plan October 2009 GIS data for the sanitary sewer network and land use were evaluated for inaccuracies. The land use data were processed for current and future loading to the sa nitary system on the parcel level. Each parcels flow was assigned to a sanitary pipe. A Capacity Model accumulated the fl ow from each parcel downstream in the sanitary network. The flow was p eaked and took into account infiltration and inflow. Pipe flows were compared against pipe capacities for possible capacity deficiencies. Capacity deficient pipes were assigned a cost for improve ment based on historical bid data. Basins were delineated based on logical groupings of pipe. 3.2 GIS Data Quality Control The Citys comprehensive GIS database was used heav ily in this Master Plan study to evaluate land use and existing pipe networks. The data were review ed and corrected based on the best available information and staff knowledge. Special data management tools were developed that assisted Master Plan users in viewing and modifying GIS data. Capacity Model data i nput and output were incorporated into the GIS database to determine capacity limita tions of the existing system and to propose sanitary infrastructure improvements. 3.3 Land Use Analysis Blueprint Denver is an essential framework document that establishes the basis for future land use planning, advocating that land use an d transportation decisions be made in conjunction. To assist with future planning, Areas of Change and Areas of Stability are delineated in Blueprint Denver Areas of Change depict expected developm ent areas based on a 2050 build-out condition. The Areas of Change data are included with the Master Plan mapping, for reference, to show the pot ential changing land use, and to highlight the areas where capital inve stment in infrastructure may be needed. Denvers Sanitary Sewer Design Technical Manual underwent a revision in March of 2008 to update policies, methods, practices, procedures, and design standards utilized in th e Department of Public Works activities. The intended purpose of the document is to provide guidelines for the design of sanitary sewers, thereby encouraging consistenc y. Loading factors have been updated to the 2008 criteria. These better suit the average metered flows observed in each zone district based on population density analysis. 2020 land use categor ies were then matched to their zone district counterpart to determine their flow factors. The Citys GIS parcel and Blueprint Denver concept land use data were used to establish sanitary sewer loading. The Capacity Model can incorporate updat es to land plans and growth rates, including the incorporation of future GIS data and graphical user interfaces. Loading factors are based on the propertys land us e/zoning. System capacity loading was computed by linking land use with loading factor s as shown in Table 3.1. For this study, two primary land use scenarios have been utilized: Year 2009 and Year 2020 from Blueprint Denver The Capacity Model applies the appropriate loading factors to the land uses. In this 2009 update to the Master Plan, demographic information was used to test existing and future land use assumptions. Population and employment data were obtained from the Denver Regional Council of Governments for the years 2005, 2015, and 2030. Areas of the City were divided into Traffic Analysis Zones. Analyses were completed, on the subbasin level, to compare predicted sanitary flow from the demographic data to the predicted flow for the land use data. A future, more refined, study will need to be conducted to thoroughly validate th e land use assumptions against the demographic information. Hydraulic modeling was completed to compare existing hydraulic capacity with anticipated future flows. Flow projections for the Ma ster Plan are based on the current zoned land use designation and Blueprint Denver modified, as necessary, to better reflect th e anticipated development of any particular parcel. The overall planning criteria for the City & County of Denver is to attempt to provide sewerage capacity to accommodate the current zoned land use or future predicted land use, not necessarily the actual existing land use. Therefore, Model data showing sanitary sewer lines unable to convey future flows may be functioning well within capacity today. However, if the entire tributary basin were built to zoned land use, there likely may be capacity deficien cies. The next step, beyond the Master Plan, is to field verify capacity-limited reaches by monitoring fl ows in the pipe before programming and designing improvements. Flow projections, using these planni ng criteria, likely result in flows that are different from the flows currently conveyed in the existing system. Parcels may not currently be built to their full land use densities. Therefore, the flows projected in this Mast er Plan may not be appropriate for final design. If the difference in flows between the current land use an d zoned/future land use is significant, replacing an existing pipeline, with a significantly larger diameter pipeline, could result in low depths that may contribute to depositional problem s a s well as poss ible hydrogen sulfide issues, including odor and corrosion.

Sanitary Sewer Master Plan October 2009 3.4 Hydraulic Loading Flow from all parcels was loaded to pipes based on proximity and knowledge of how the flow connects into the system. Spider lines were used to graphica lly represent the connection of a parcel to a pipe. Spider lines, in red, are illustrated in Figure 3.2. 3.5 Mannings Peaking Factors To determine the adequacy of the sanitary sewer pipe s to convey the flow, a peaking factor is generally applied per the Sanitary Sewer Design Technical Manual The peaking factors are based upon average daily flow rates. As the sanitary basins become larger, the peaking factor decreases. During the 2006 effort, the equation used was: peaking factor = 3.8 x (ADF)-0.17; where ADF is the Average Daily Flow in cubic feet per second with the peaking factor cappe d at 5.0. The 2009 effort caps the peaking factor at 4.0 and uses the equation: peaking factor = 2.6 x (ADF)-0.16. The Denver Wastewater Metering Program records, for over 20 years, were used to determine the change in the peaking factor equation. This study was the basis for changing the design criteria. 3.6 Capacity Modeling The Capacity Model approach was used throughout the City to simulate the ope ration of the City owned and maintained sanitary sewer collection system for the sanitary basins under current (2009) and future (2015, 2020, 2030 and 2050) scenarios. The Model is based on the assumption that flow is steady through time. The goal is to predict the maximum flow that could be possible and plan to meet those conditions. The systems ability to convey wastewater loads under dry and wet situations was analyzed. Maximum flow is determined by multiplying the aver age sewer flow by a peaking factor and adding infiltration and inflow. This Master Plan used a consta nt infiltration and inflow rate of 500 gallons per acre per day for sanitary sewer design. The Mode l accumulates the flow downstream through the sanitary sewer pipe network. Reaches of pipes that were at, or near theoretical capacity, were identified for improvements in this Master Plan. Upsizing of capacity limited pipes was based on Mannings Equation, which takes into account pipe diameter, sl ope, and a friction factor. Mannings Equation relates pipe flow as a function of pipe slope and diameter. 3.7 Deficiencies Based Upon Current Criteria The Model output was symbolized to identify, by color coding, all pipe sections with surcharging or d/D (design hydraulic depth to pipe diameter ratio) values at specified levels. This color coding allowed City staff to identify sections that are nearing or at cr itical threshold levels. Th is Master Plan document utilized the model results to indicat e system capacity deficiencies shown herein on basin/subbasin maps. Pipes in blue will theoretically be operating, based upon allowable land use, at 86% or less hydraulic capacity. Pipes shown in purple will theoretically be operating above 86% but less than 100% of hydraulic capacity. Although this may be beyond the cr iteria of 80% of full flow depth for new pipe, this shows that the existing system should be capable of handling build-out flows. These pipes may need to be monitored in the future. Pipes shown in heavy black will theoretically be op erating at or over 100% hydraulic capacity. These pipes could be identified as capital improvements based upon exceedence of hydraulic capacity. Figure 3.3 depicts a cross section of pipe with these three categ orized levels of flow. Figure 3.4 illustrates a typical pipe reach under study for upgrade.

PAGE 12

Sanitary Sewer Master Plan October 2009 The Proposed Improvements designation identifies the diameter, in inches, in bold, black numbers along the pipe reach. The pipes capacity shall be such that the sewer is flowing at no more than 80% of the full depth at the calculated peak flow rate. A depthvariable friction factor shall be used such that the partial flow rate at 80% depth is approximately 86% of the sewer's full-flow capacity. The peak sewage flow rate shall be equal to the summation of commercial, industrial, and residential average flows multiplied by an appropriate peaking factor plus an infiltration and inflow (I&I) allowance. Required sewer capacity = ((peaking factor x average sewage flow) + I&I) /0.86 The proposed capital improvements are shown as complete replacement with a circular pipe having conveyance capacity for the approp riate level of service based upon potential land use. Conflicting utilities, and other constraints, may necessitate infrastructure equivalents such as parallel pipes. Capital improvements are based upon the slope of the new pipe matching the slope of the existing pipe. Shallower slopes, determined during preliminary design, may necessitate larger pipes. This Master Plan shows the proposed capital impr ovements as a basis for evaluating sanitary sewer upgrades by recommending removal of the existing pi pe and replacement with the larger new pipe. Further study will be required to determ ine specific project scope. Additional study (beyond the scope of this Master Plan) will evaluate the condition of th e existing pipe, calibrate the theoretical flows with meter flow data, and potentially pr opose alternative capital improvement projects. Such alternatives include constructing a parallel pipe slip-lining the existing pipe, proposing a new pipe alignment, or accepting existing conditions where flows can be accommodated in a full flow pipe. 3.8 Basin Delineations Basins for the Denver sanitary sewer system were defi ned, by the existing pipe network, from the point where they outfall to the Metro sewers. Outfall poin ts to Metro sewers were identified and subbasins were defined as sanitary sewers tributary to a single Metro interceptor. This was a starting point for basin delineations which were refined for manageable areas of study, referred to as Map Groups, for purposes of this Master Plan. Subbasins have been grouped and displayed for map presentation at a 1 = 1,200 foot scale in an 11x17 format. Each map incl udes general planimetric features, street names, rights-of-way, existing sanitary sewers with a size designation, pipe material and direction of flow, legend, and key map. The Central Business District, of downtown Denver, wa s the initial focus of the Sanitary Sewer Master Plan. This basin was selected as a prototype for es tablishing planning criteria and data management processes. These protocols were applied to the Citys remaining basins. The next phase of the Master Plan built upon the initial work by confirming wastewater flow criteria, evaluating and improving GIS sanitary sewer network integrity, applying a Capacity Model approach per the Citys Sanitary Sewer Design Technical Manual developing a process for assessing sewer system condition and rehabilitation, and identifying collection system deficiencies for all sewer system basins. After completion of the Central Busine ss District basin, the Master Plan focused on basins with Areas of Change as defined by Blueprint Denver Locations in the Areas of Change include the new growth areas of Lowry, Stapleton, Gateway, downtown, areas arou nd transit stations, and areas along major streets and/or transportation corri dors. These locations benefit from an infusion of population, economic activity, and investment. The final effort of this Ma ster Plan analyzed the remainder of the City for deficiencies, and developed recommended capital im provements for implementation based solely upon capacity. 3.9 Water Quality Considerations There is concern th at sanitary sewer pipes could experience exfiltration with flow being intercepted by storm sewers and conveyed to the receiving wate rways. The existing GIS network was used to characterize the interaction between the storm and sani tary sewer systems. The Denver GIS database was used to determine intersection crossings of storm and sanitary pipes. The greatest concern is intersections where sanitary pipes may be installed through storm pipes. Secondarily, there are concerns where storm pipes cross below sanitary pipes. This also applies to areas where the pipes are closely parallel or cross within 12-inches of each other. Areas where sanitary mains cross under storm pipes are noteworthy, but less of a direct threat to water quality. The ongoin g Storm and Dry Weather Monitoring Program has been aided by identifying these areas of pipe intersections. Maintenance programs are being developed to inspect these critical storm/sanitary pipe intersections.

Sanitary Sewer Master Plan October 2009 4.0 CAPITAL IMPROVEMENTS PROGRAM 4.1 Cost Modeling Cost estimating is an important co mponent of the master planning proc ess. Costs have been compiled to assist in the evaluation of sanitary upgrades, and to provide for systematic capital budgeting for future improvement programs. Bid data has been obtained, from the City & County of Denver, for the period 1999 to 2005 and reflects typical construction practices within the City. To convert costs to 2008 dollars, from 2005 dollars, all costs were escalated 7% except for the cost of asphalt patch which was doubled. A detailed tabulation of all unit costs, and a listing by map group, is shown in the Technical Appendix and linked to the GIS database for proj ect cost analysis. General unit co sts (in 2008 dollars) are summarized below with sanitary sewer pipe costs charted in Figure 4.1. Sanitary Sewers: 8 $ 64 per lineal foot 10 $ 67 per lineal foot 12 $ 71 per lineal foot 15 $ 76 per lineal foot 18 $ 81 per lineal foot 21 $ 92 per lineal foot 24 $ 102 per lineal foot 27 through 96 $ 4.00 per inch diameter per lineal foot Jack and Bore Pipe: $ 21.40 per inch diameter foot Manholes: $ 3,040 each Type A (4 diameter pipes less than 30) $ 4,570 each Type A (5 diameter pipes 30 to 36) $ 7,865 each Type B (pipes greater than 42) Tabulated in GIS and based on replacement of existing manholes Asphalt Patch (assumed 8-ft $ 8.00 per sy-in ($145.46/ton) for wider than the pipe diameter): assumed 9-inch full depth section Wet Utility Relocation Cost: $3,210 to $21,400 per crossing for storm sewer $1,070 for relocation/av oidance of water Wet utility crossings have been tabulated in GIS for each specific pipe run and are included in the cost model based upon the size of the conflicting pipe. Costs are for sleeving, relocation, and protectio n during construction. Dry Utility Administration Cost: 5% of direct construction costs Removal of existing sanitary sewer pi pe has been considered incidental to the new pipe construction and is included within the new pipe unit costs. The following index values, from December 2008, can be used for future baseline comparison: National Urban Consumer Pr ice Index (CPI) = 210.228 Engineering News Record Construction Cost Index (ENR CCI) = 8551 CDOT Construction Cost Index (CDOT CCI) = 330.1 Indirect costs have been expressed as a percentage of direct construction costs.

The specific proposed features breakdown, of the cost estimate by map group, is shown on the adjoining page for every map gro up. Costs are tabulated programmatically using GIS and are based upon unit prices developed in 2008. This Master Plan does not distin guish between developer cost and City cost. In particular, capital improvements have been shown for new developing ar eas (i.e., Stapleton). Their funding will be borne by different entities and budgets when compared to retro-fit improvements of existing development.
