SMUGGLER/HUNTER SURFACE DRAINAGE MASTER PLAN
SCOPE OF WORK
1 . INTRODUCTION
The City of Aspen (the City) is requesting sealed proposals
from interested Civil Engineering Consulting firms for the
Hunter/Smuggler Surface Drainage Master Plan Project
(Project) . The objective of the Project is to compile a
document which provides a clear and concise explanation of the
City' s existing stormwater system, establishes stormwater
management goals for the future, presents tools to meet or
exceed established goals and provides a foundation for future
policy and/or project decisions .
2 . BACKGROUND
Aspen is a resort community located at 7, 900 feet in elevation
within the Elk Mountain Range and is approximately 200 miles
southwest of Denver, Colorado. Aspen receives about 25 inches
of rain each year, as well as 300 inches of snow, and is in a
relatively flat valley floor surrounded on three sides by
Aspen, Smuggler, and Red Mountains . The Roaring Fork River
flows through the middle of Aspen and is considered a Gold
Medal Trout Stream upstream and downstream of Aspen' s City
limits . Development within Aspen typically consists of
upscale residential and commercial redevelopment, often on
less than 1 acre and rarely on parcels larger than 3 acres .
Aspen attracts world-class athletes, musicians, political and
religious leaders, and outdoor enthusiasts . Because of
Aspen' s long time commitment to protection of the environment,
recognition as a world leader in innovative and progressive
movements, and because Aspen discharges into pristine Colorado
waters, rigorous stormwater standards are necessary and
supported.
Currently the City has a Surface Drainage Master Plan, which
includes the area within the City limits south of the Roaring
Fork River, with a western boundary of Castle Creek and an
eastern boundary of the Ute Cemetery. This plan was completed
in November of 2001 by WRC Engineering, Inc. and copies are
held in the City of Aspen' s Engineering Department . The
Surface Drainage Master Plan analyzes the given area and
estimates the amount of surface runoff expected and the
direction this runoff will flow. It analyzes the existing
drainage facilities and determines which facilities cannot
convey this flow without flooding. The plan evaluates upgrades
and capital improvement alternatives, along with cost
estimates for these alternatives .
Agreement Professional Services Page 11
In April of 2010 the City adopted an Urban Runoff Management
Plan in order to provide minimum standards and technical
guidance that address stormwater runoff in the development and
redevelopment of the City of Aspen. This plan is intended to
assist homeowners, developers and their consultants with the
design of their development as it relates to stormwater
management .
As the City continues to improve its stormwater management
standards the Hunter/Smuggler Surface Drainage Master Plan
Project will expand on the coverage of the current Surface
Drainage Master Plan and employ the standards outlined within
the Urban Runoff Management Plan. With the development of this
Project the majority of the City, east of Castle Creek, will
be encompassed in a Surface Drainage Master Plan allowing for
continued progressive management of the City of Aspen' s
stormwater.
3 . WORK DESCRIPTION
The purpose of this Project will be to develop a Surface
Drainage Master Plan (the Plan) for the Smuggler and Hunter
Creek drainage areas within the City of Aspen; the area north-
east of the Roaring Fork River and south-east of Hunter Creek,
as seen in "Figure 1" . The Plan will inventory the existing
stormwater conveyance system, evaluate the capacity of the
existing infrastructure, evaluate improvement alternatives,
and prepare a comprehensive plan for improving identified
stormwater system deficiencies, including both quantity and
quality perspectives . Ultimately, existing and future problem
areas will be identified and prioritized and recommended
design concepts will be presented.
3 . 1 . Scope of Work
The selected Consultant will provide professional services
that include, but are not limited to:
3 . 1 . 1 . Define Existing Stormwater Management
Infrastructure:
The Consultant shall collect and review existing
drainage facility data for all stormwater conveyances
and structures, inlets, pipes, culverts, swales, and
tributaries to the Roaring Fork River and Hunter Creek.
The Consultant should collect existing curb and gutter
information from the City' s GIS and Engineering
Departments . Additionally the Consultant shall collect
and review information related to the network of
Agreement Professional Services Page 12
irrigation ditches and structures . The inventory efforts
will involve the location, attribution, verification or
correction of the existing data as necessary, creation
of new data as necessary, and GIS mapping of the system.
The current design capacity of all structures and
natural channels shall be analyzed, under existing
conditions .
A comprehensive hydrologic and hydraulic analysis should
be conducted utilizing GIS-based platform. The
Consultant shall utilize CUHP and SWMM modeling systems .
Hydraulic modeling shall be completed with consideration
of both surface runoff and snowmelt, running the model
for the two year, five year, ten year, twenty-five year,
and one-hundred year flow conditions . The Consultant
shall develop a stormwater model with linked results .
The existing open channels and closed systems are to be
modeled in order to estimate the water surface
elevations for each of the peak flows determined in the
hydrologic model . The hydraulic model (s) should be
capable of accurately modeling both open and closed
stormwater conveyance systems . The Consultant shall
utilize CUHP and SWMM modeling systems . The basis of
standards for this project shall be the current Urban
Runoff Management Plan.
Potential problem areas or areas of conflict should be
noted and explained in the Plan. Examples of potential
problem areas include deficiencies in the existing
systems, poor water quality or contamination issues,
areas of excessive erosion due to poor stormwater
management, and identification of existing facilities
that are not able to function within the requirements of
current local, regional, state and federal codes and
regulations under peak flow conditions .
3 . 1 . 2 . Water Quantity:
The Consultant shall utilize CUHP, SWMM, and HEC modeling
systems to identify Flood Hazard Zones if not identified by
FEMA. FEMA and the Colorado Water Conservation Board are
currently updating the floodplain maps within the study
area. The draft floodplain maps from 2011 should be used in
the development of the master plan. Areas with a history of
flooding shall be analyzed in detail in order to determine
the adequacy of the existing drainage facilities and
Agreement Professional Services Page 13
requirements for future development within the area.
Specific areas that have been identified are:
✓ Spruce Street
✓ McSkimming Rd
The Consultant shall prepare a Regional Drainage Areas
coverage map.
The Consultant shall prepare a Drainage Basin Areas
coverage map.
3 . 1 . 3 . Water Quality:
The Consultant shall identify potential locations for
regional water quality improvements . Based on system
review the Consultant shall help staff develop, refine
and prioritize a list of future water quality projects .
Existing wetland and riparian areas should be identified
and mapped.
3 . 1 . 4 . Debris and Mud Flows :
The Consultant shall identify any areas of potential
debris and/or mud flow hazards . The hazard potentials
shall be modeled using the FLO-2D modeling system. The
Consultant shall model the two year, ten year, fifty
year, and one-hundred year flow conditions . The node
spacing used in the model should be 50 feet or less . All
input conditions and outputs shall be provided to the
City, both as a report and in plan form.
3 . 1 . 5 . Mine flows :
The Consultant shall identify any areas of potential
mine water outflow. The Smuggler Superfund Site is
located within the study area boundaries and any water
coming from the superfund or mining site should be
documented in the master plan.
3 . 1 . 6. Irrigation:
The Consultant shall compile existing information on

5. WORK DESCRIPTION
5.1. Scope of Work
Aspen has grown across the Roaring Fork River into the Hunter- .,, ,
Smuggler Basin (Basin)over the past decade and now needs a _ •. "•Surface Drainage Master Plan for the area to understand the • '' ` fi6.`� t k
existing stormwater conveyance system and associated
stormwater issues. This project will produce document to ti
complement the existing 2001 Surface Drainage Master Plan - _ -
(Plan) and provide guidance for stormwater management in the = ,.�.':'�.
area that is compliant with Aspen's recently adopted Urban . .
Runoff Management Plan(URMP) (AMEC Earth and ' ; `:
Environmental, et. al., 2010). The URS Team will implement the process
To help understand the geographical extent of the study area, we have used to successfully deliver
we prepared Figure 2, a study area map, shown on the following master planning projects for several small
communities within the last 5 years,
page. There is a need to address storm drain system capacity, including Delta,CO,5-2-1 Drainage
debris and mud flow potential from the upper Basin on Smuggler Authority in Mesa County,CO;Gillette,WY,
Mountain, mine and irrigation flows, and stormwater quality. and Casper,WY
Potential infrastructure improvements for the 20-year planning
period, including upgrading the system to a 10-year event capacity, will be evaluated. Additionally,
potential solutions will be evaluated for Aspen's current problem areas along Spruce Street and
McSkimming Road. Ultimately,the URS Team will prepare a comprehensive plan documenting,the
analyses completed and the recommended plan of improvements.
Generally,this project requires:
• Inventorying existing drainage facility data, including surface conveyance and irrigation ditches
and structures
• Building and executing existing and future conditions hydrologic and hydraulic models
• Identifying problem areas and/or areas of conflict
• Identifying potential locations for stormwater quality facilities
• Evaluating potential debris and mud flow area
• Identifying mine water outflows and evaluate impacts on the storm water system
• Evaluating and documenting the capacity of irrigation facilities
• Conceptually designing infrastructure improvements to evaluate the relative merit and financial
and physical feasibility
A coordinated effort between the URS Team and Aspen staff is essential to a successful project.
Working with GIS and asset data provided by Aspen and additional asset information obtained by
survey,the URS Team will efficiently build hydrologic and hydraulic models and perform the evaluation
of existing drainage infrastructure. With Aspen providing criteria for proposed projects,the URS Team
will develop and evaluate projects and recommend improvements. Successful public relations and
presentations will rely on a solid working relationship between the URS Team and Aspen staff.
Our approach to accomplishing the project requirements in a timely and cost-effective manner includes
parallel efforts by the URS Team. Our approach is described according to the tasks laid out by Aspen in
the RFP in the following paragraphs. The proposed project schedule is shown in Figure 5.

Task 1-Define Existing Stormwater Management Infrastructure
Data Collection
For a new master plan, data collection is an essential first step in developing the project analyses. The
URS Team wif begin by collecting the resource information available from Aspen. Our Team has already
reviewed and is familiar with much of the resource information provided in the RFP. Other key
resources that are relevant and need to be incorporated into the project include:
• Aspen's GIS information and aerial photo data:these items will provide the initial basis for
modeling. Our Team is well versed with utilizing GIS to develop drainage master plans.
• The 2012 Aspen Area Community Plan and the Aspen's zoning information. These items will
assist in planning the future growth areas and determining future land uses that will be
incorporated into the hydrologic analysis.
• As-built, record drawings of stormwater conveyances and structures, including;inlets, pipes,
culverts, and swales.This information will be incorporated into the GIS database and used for
hydrologic modeling.
• The Salvation Ditch and Canal traverse the study area. Available information from the ditch
owner will be obtained and used in the evaluation of ditch capacity.
• The draft FEMA Flood Insurance Study and Flood Insurance Rate Maps for Pitkin County will
provide valuable information regarding flood plain areas and for calibrating and establishing the
hydrologic analysis.
• Anecdotal information from Aspen and area residents regarding flooding,drainage,
maintenance, and erosion problems.
A field survey of the stormwater conveyance system will be completed. Survey will include the spatial
location,dimensions, materials,inverts,and condition of all hard storm features such as curbs,gutters,
inlets,manholes, storm sewer pipes,culverts,and bridges. All field survey work for the project will tie in
to Aspen's existing control and will be captured in survey feet in the Stateplane Colorado Central, FIPS
Zone 0502 coordinate system, referenced to the North American Datum of 1983(NAD83)and the
National Geodetic Vertical Datum of 1929(NGVD29).
A site visit to understand key drainage features and flow patterns and to photograph the site will be
completed. Field observations will be documented and used for project modeling and
recommendations. The site visit will be augmented by specific site inspections that can be made before
and after coordination meetings. Site visits will be aided by preparation of field map books showing the
GIS data with an aerial photograph and ground surface elevation contours,which will be included in the
Technical Appendix of the Master Plan.
Relevant data from the survey and reference resources will be tabulated and compared with the existing
GIS data. Where the existing GIS data is lacking or determined to be inaccurate,it will be updated using
the references and/or survey data. All pertinent system data will be compiled and populated in the GIS
database for use in the modeling.
Deliverable:
• Stormwater conveyance system inventory in ARCINFO shapefile format
Assumptions:
• Aspen will provide the GIS information identified above and will assist in determining relevance
of information

Task 2 - Design Capacity Evaluation
2.1 Hydrologic& Hydraulic Analysis
The major basin for the Hunter-Smuggler watershed is shown on the study area map, Figure 2. The
watershed will be subdivided to capture design points on the existing drainage systems, including the
storm sewers, drainageways, and irrigation ditches. GIS metnods will be used to delineate the sub-
basins on Aspen's 1-foo: contours in and just outside Aspen's limits, and Pitkin County's 10-foot
contours will be used for sub-basin delineation within the upland areas. The URS—earn will provide the
basin de ineations in GIS format to Aspen for review and approval prior to beginning hydrologic
ca culations.
Rainfall-runoff and rainfall-snowmelt runoff hydrographs for the 2-, 5-, 10-, 25-, 50-, and 100-year
recur-ence intervals for existing and future basir conditions will be calculated. The Colorado Urban
Hydrograph Procedure 2005, version 1.3.3,will be used for modeling the rainfall events. InfoSWMM,
which is a GIS-based platform for the construction and implemertat on of SWMM models,will be used to
develop snowrrelt data to combine with the CUHP hydrographs. Evaluation of the 50-year event is included
to inform the mud flow analysis that is described in Task 3. Basin parameters for each method will be
developed using GIS methods along with the reference data provided in the Urban Runoff Management
Plan (URMP),the Urban Storm Drainage Criteria Manual (Urban Drainage and Flood Control District,
2001), and the CUHP and InfoSWMM manuals. The future conditions analyses will be based on future
land use data developed using Aspen and Pitkin County's zoning and planning data. The resulting
hydrographs will be reviewed with the Aspen Project Manager prior to rcuting the flows,
A combine probability analysis will be performed to determine the equivalent recurrence interval for the
combination of rainfall-snowmelt events for later use in determining which events are most restrictive.
The LRS Team proposes routing flows usirg InfoSWMM. InfoSWMM uses the same math engine that is
used In EPA SWMM 5 and it provides results linked to the features created in G S. The URS Team has
successfully implemented InfcSWMM on several recert master plans and has found that it s a stable,
reliable platform with the capability of analyzing both open and closed conveyance systems and works
well in evaluating the hydraulic capacity of closed systems. Additicnally,the hydrologic output of
InfoSWMM is easily combined with HEC-RAS to complete step-backwater analyses to develop water-
surface elevations and flood hazard information along open conveyance`acilities.
Routing elements for surface and underground conveyances to be modeled will be created using GIS
methods from the inventory data gathered from suvey and -eferences. Modeling nodes will be placed
at junctions and locations of interest, including tie design points identified in the subbasin delineation.
The HEC-GeoRAS extension for A-cGIS will he used to develop geospatially-referenced input data for the
HEC-RAS models and, subsegi.ently,to develop geospatially-referenced flood hazard zone delineations
using the HEC-RAS model output.
The Salvation Canal and Ditch,which crosses through the study area as shown on Figure 2,will be
evaluated along with its relationship to the stormwater conveyance system. Special consideration must
be given to routing of stormwater flows to determine whether the canal is removing or contributing
flows to the basin.
The effects of possib e crainageway,outfall system,detention, and irrigation system projects will be
incorporated to estimate the changes in stormwater routing. Results of the final hydrologic and
URSPage I 15
poSUt? #20-2-41i

hydraulic calculations will be presented to Aspen in the progress meeting. Final results can be provided
in EPA SWMM or InfoSWMM format.
Deliverables:
• Basin delineations in ARCINFO shapefile format
• Existing and Future Conditions CUHP rainfall-runoff hydrographs
• Existing and Future Conditions SWMM rainfall-snowmelt runoff hydrographs
• Initial InfoSWMM and HEC-RAS calculations
• Drainage Basin Areas Map
• Regional Basin Areas Map
• InfoSWMM Model Schematic
• Analysis discussion for Master Plan
2.2 Problem Area Identification
Using the results of the Hydrologic and Hydraulic analysis, problem areas and area of conflicts will be
identified. In identifying these areas, consideration will be given to the following factors:
• Capacity deficiencies
• Issues with water quality or contamination
• Excessive erosion
• Functional deficiencies based on the requirements of local, regional, state and federal rules and
regulations
Problem areas will be identified on a map for review with Aspen and for inclusion in the Master Plan.
Detailed descriptions of the identified issue(s) in each location will be included in the Master Plan.
Deliverables:
• Problems Areas location data in ARCINFO shapefile format
• Problem and Deficiencies Areas Map
• Problem Areas discussion for Master Plan
2.3 Water Quantity
The URS Team will use the Draft FEMA FIRMs, Aspen's GIS data, and anecdotal evidence to identify
surface conveyances where Flood Hazard Zones are needed but have not been identified by FEMA,
particularly in those areas that have a history of flooding. For example, the URS Team has learned that
Spruce Street often floods because there is no existing stormwater conveyance system along the road
and that many high-value homes along McSkimming Road often experience flooding from the upland
trail systems above Smuggler Mountain Road. These areas along with others that may be identified will
be analyzed using the InfoSWMM and HEC-RAS models to estimate the capacity of the existing systems
and identify requirements for future development.
The URS Team considered using FLO-2D to evaluate flood hazards. However, use of FLO-2D for that
purpose requires the independent analysis of hydraulic structures such as bridges and culverts using a 1-
dimensional method such as HEC-RAS or Flowmaster. The results of the independent analysis are then
incorporated into FLO-2D as rating tables for the 2-dimensional analysis. The URS Team believes that
the level of effort over and above what would be required for a HEC-RAS model is not warranted for
potential flood hazards in this drainage basin. HEC-RAS will sufficiently provide flood hazard zones and
is consistent with methods currently in use in Aspen.

Deliverables:
• Flood Hazard Zone data in ARCINFO shapefile format
• Flood Hazard Zone Maps
• Flood Hazards discussion for Master Flan
Assumptions:
• Draft FEMA FIRMs and documented anecdotal reports for flooding w II be made available by
Aspen
2.4 Water Quality
The UR5 Team will perform field investigations to identify existing wetlands and r parian corridors,
including near bank areas along the Rearing Fork River and Hunter Creek. This field investiga:ion will
occur durirg the growing season when these features are most readily inventoried. Using the
wetland/riparian corridor delireations and the results of the analyses described in previous sections,the
URS Team will perform a system review and identify potential locations for regional water quality
improvements. When considering locations,tie potential for multi-use facilities will be evaluated along
with the potential water-quality functionality.
Deliverables:
• Prioritized list of future water quality projects for inclusion in Master Plan
• Wetlands and riparian corridor delineations in ARCINFO shapefile format
• Wetlands and Riparian Corridor Maps
Task 3 - Debris and Mud Flows
The URS Team will conduct a field reconnaissance,study the feld soil condition and s ope stability, and
identify areas of potential debris aid/or mud flow hazards. We will then apply the FLO-2D modeling
sys:em to model the mud/debris hazard potentials in the watershed for the 2-, 10-, 50-, and 100-year
flow conditions, assuming:wo flow co-dit ons—mud flood (with sediment concentration less than 50%
by volume),and mudflow(with sediment concentration greater than 50%in volume). To provide
sufficient resolution to mud/debris hazard delineation, UPS will use node spacing of 50-feet or less for
the FLO-2D modeling. Streets will be specified in the model, as well as the buildirgs along the flow path.
Bridges/culverts may be assumed to be blocked depending on the dimensions of:he openings.
Deliverables:
• FLO-2D Model Report
• Mudflood/Mudflow hazard data in ArcINFO shapefile format
• Mudflood/Mudflow Hazard map
• Mud and Debris Flow discussion for Master Plan

Task 4-Mine and Irrigation Flows
The Smuggler Superfund Site sits squarely in the middle of r
the study area It was placed on the National Priories List
(NPL) in 1985 for high levels of lead and cadmium in the 'e--
soil, but it was deleted from the NPL in 1999 after study _ - - 4
and reclamation activities. Aspen has adopted institutional . r.{ '
controls including permittirg of the movement of any , l'- jai,
volume of soil greater than one cubic yard from the permit :
rte- .-
area. Areas requiring special permitting are shown on
Figure 3. Smuggler Mine is still in operation.
Although the most recent available documents for the C _ _, ,7 GI
Smuggler Mine indicate no surface water problems,dry "' `- `y`
4 war Y".�,..rr..... �. y�W... M.mL
weather flows will be noted during the survey,and care " �r, N
will be taken to follow them to a source. Also, if the URS is aware hat the U.S.Forest Service has sonic
presence of yellow bcy,or ferric oxide precipitation, is involvement with Smuggler Mountain Road LRS wit
noted In the drainageways,then it will be mapped along coordinate wth them regarding stormwater issues
with the structures. For this proposal,we do not expect to along the road as applicable to this Master Plan
find any dry weather flows except for irrigation flows,
Hunter Creek and the Roaring Fork River, and we do not expect to find any yellow boy.
The Salvation Ditch (a.k.a. as the Salvation Canal),visible in Figure 2, cuts across dra•nage paths through
the study area and attracts the focus for diversion and conveyance of stormwater. The Salvation Ditch
has senior rights cn the Roaring Fo-k River dating to 1902 and 1929, according to the Colorado Decision
Support System data.There is a conflict between some Aspen citizens and the ditch users because the
ditch diverts water from the Roaring Fork River right above Aspen and can, in dry years,severely reduce
the flow in the river as it runs through Aspen. Some Aspen citizens would like to see the flow in the river
for aesthetic and envircnmertal reasons.
From a stormwater perspective, ditches often divert some stormwater but ofter only minor flows.
During large sto-ms the flow can split into two or more directions. Most ditches are not large enough to
carry major storm flows. In most stormwater master planning projects,the oper channel flow water is
assumed to cross the ditch at the point of attack, as though the ditch berms
do not exist at the drainageway.The Salvation ditch is decreed for at least 25 • �'..a
cfs, which is enough to divert significant storm flow,and this may not be a 'f• •
safe assumption. The URS Team will assess the ditch from this perspective �I`
and evaluate its potential for stormwater diversion.We will also assess any .-.

Task 5-Improvement Recommendations
5.1 Alternatives Analysis
The URS Team will prepare a list of needed stormwater conveyance and detention improvements. The
URS Team will work closely with Aspen to identify potential prcjects that address the improvement
needs. Cost est mates for the potential improvement projects will be prepared and documented in the
master plan.
Proposed improvements will be tailored to the problem locations and be evaluated in accordance with
the URMP. Proposed improvements will likely include regional and/or sub-regional detention, channel
improvements, storm drain improvements, irrigation ditch imp-ovements,floodpla n management, anc
other options suggested by Aspen and identified during analysis and evaluation. For areas needing
stormwater conveyance improvements where none currently exist, preference will be given to open
conveyance systems versus closed systems, in accordance with Aspen's goals of reducing runoff and
increasing infiltration. Recommended projects will be identified and conceptual designs prepared. For
dentention or water-quality pond facilities,the most current version of Autodesk's Civil 3D CADD
software will be used to prepare conceptual layouts. Conceptual profiles for recommended storm
sewer system improvements will also be prepared in CADD. Conceptual layouts for proposed facilities
will be converted to GIS format and shown on an overall map.
Conceptual level cost estimates will be prepared for each project and the impacted population, being
current customers or future development areas, will be assessed along with any regulatory permitting
needs, right-of-way acquisiticn, and operational requirements. The system deficiencies and proposed
projects will be prioritized based on a ranking system that includes ris< of personal injury or property
damage,cost/benefit analysis, and level of flood protection deficiency at a minimum. Additional factors,
such as long-term maintenance needs, positive effects on water quality, opportunities for multi-use and
community use,and wetlands/wildlife habitat enhancement may also be considered, at Aspen's
discretion. The financial and physical feasibility of each improvement will be determined and the
benefits of the different alternatives compared. The recommended capital improvement projects will
be identified on a map, and a detailed description of the project, costs, and impacted population will he
provided in the text of the final report. The recommended improvements w II be incorporated into an
overall capital improvement plan for the Aspen's 20-year future planning period. Cost estimates will
include costs associated with property or right-of-way acquisition, design, environmental and
geotechnical evaluations, survey needs, administration, -egulatory agency permitting, construction
management, and construction.
5.2 Upgrade to 10-Year Event
As part o=the Improvement Recommendations task, the URS Team will evaluate what upgrades are
needed to improve the existing stormwater conveyance system to a 10-year event capacity. Each
facility improvement will be evaluated and mapped as described above. Separate cost estimates will be
prepared for the upgrades.
Deliverables:
• List of facility needs for review with Aspen
• Prioritization matrix
• Lists of Recommended Projects
• Maps of Recommended Projects and Storm Sewer System Upgrades
Agreement Professional Services Page 27

Assumptions:
• Aspen will make available assessor's data cr other property valuation data
• Aspen will make available recent project cost data
Task 6-Master Plan
Report Document
The URS Team proposes 50%,90%,and Final submissions of the Surface Drainage Master Plan. The 50%
submittal will follow completion of the Design Capacity Evaluation, Debris and Mud Flow and Mine Flow
analyses. The 90%submittal will follow completion of the Improvement Recommendations. The Final
submittal will incorporate the final project results,the executive summary, and Aspen's final review
comments.
In addition to these formal submittals,the URS Team anticipates a series of informal reviews and interim
deliveries to Aspen as shown on the proposed project schedule in Figure 5. Pr or to progress meetings,
URS will submit GIS datasets and preliminary calculation results for review by Aspen. These interim,
informal reviews will provide opportunit es for the URS Team to col aborate with Aspen to validate
project progress, aid wi I inform the Surface Drainage Master Plan. Per Aspen's preferences,these
informal and interim deliveries will be made via email.
The Surface Drainage Master Plan will be a comprehensive plan describing, in detail.the project process,
including details of analyses performed; alternatives considered, including the benefit/cost analysis;and
a f nal list of recommended capital improvement projects. Figures,summary tables, and comparison
tables will also be included. CUHP,SWMM, HEC-RAS, and FLO-2D modeling inputs and outputs will be
provided both in report text and map form. Tie project will also be conc sely summarized into a
comprehensive Executive Summary'within the plan.
The Master P an will be prepared in both paper and electronic formats. Up to 20 copies of the draft and
final plan will be provided. Web-ready PDFs of the final plan text and appendices w II also be provided.
Foe ease of download, it is anticipated that the plan will be divided into separate PDFs by section. The
URS Team anticipates preparing the plan text in a two-column landscape format on tabloid paper to
maintain consistency with Aspen's existing 2001 Storm Drainage Master Plan, although the format can
be changed at Aspen's discretion. Additionally, for ease of use by Aspen,the Master Plan will be
organized similar to the existing 2001 plan. Appendices will include the figures,tables, project
correspondence, and tabular input and output for the CUHP, SWMM, HEC-RAS, and FLO-2D models.
Mapping
Base sheets will be developed for the project area for mapping project data. The final sheets will include
the watershed hydrologic mapping, hydrologic model schematic and existing drainage facility inventory,
flood hazard zones, mudflow zones, and the final recommended master-planned facilities. The URS
Team proposes preparing these maps in ArcGIS format, with supporting data developed in Civi 3D as
needed.
Mapping data for the project will tie in to Aspen's existing control and will be in the Stateplane Colorado
Central,FIPS Zone 0502 coordinate system,referenced to the North American Datum of 1983 (NAD83)and
the National Geodetic Vertical Datum of 1929(NGVD29). All data layers provided in ARCINFC shapefile
format will include metacata in accordance with Federal Geographic Data Committee standards.

Task 7-Project Management
Generally,our philosophy on each project is to provide deliverables that are valuable and useful, and
considered "right for the community." We have significant experience completing projects such as this,
and will approach this Surface Drainage Master Plan project with an impartial, open mind. We will listen
to Aspen and various stakeholders and their ideas for meeting project objectives.
Strong project management is crucial to meeting Aspen's goals and objectives of this project, and our
project management approach consists of:
• Assigning experienced technical personnel to key positions and maintaining that continuity
• Developing a project execution plan and communications procedures
• Maintaining regular communications (PXP) Aspen's Project Manager and the project team on
directives, schedule, and budget
• Monitoring the project throughout all phases for value engineering opportunities
URS has assigned an experienced Project Manager to this project. David Merritt has successfully
completed major water resources projects with a similar level of required multi-discipline coordination,
and will be assisted by senior managers at URS. Our basic approach to managing and completing
projects is to prepare the project execution plan (PXP)to meet the client's expectations and
requirements for the project, work the plan, and measure performance.

participation facilitates understanding and
improves decisions by bringing all issues and perspectives to the table. Sustainable decisions are those
that are technically feasible, economically viable, environmentally compatible, and publicly acceptable.
The intent of a good communication plan is to proactively conduct an extensive and broad program to
involve Aspen officials and the public in the development of the Surface Drainage Master Plan. Applied
effectively, this plan can form a bridge between the community and governmental agencies.
Working with Aspen,the URS Team will develop the communication plan and assist in its execution.
Aspen will direct the internal and public communication plan, and will review and approve all plan
activities. Steps to developing the communications plan are:
• Identify Stakeholders-During the course of the project,the list may be reviewed for
recommendations for additional organizations that should be included
• Establish roles and responsibilities -Essentially all Aspen and URS project personnel have
responsibilities for fostering relationships internally,with agencies,and with the public.
• Develop the Communication Plan-This Plan will be developed during the kick-off meeting with
Aspen. Specific elements of the plan would include:
Communications protocols between the URS Team and Aspen
Aspen internal presentations and workshops
Aspen public communications, e.g. newsletters, website, public meetings
The plan is intended to provide the strategies and tools necessary to adapt to the needs of Aspen for
various forms of communication or collaboration throughout the planning process.
• Execute the plan—The plan will be reviewed and updated as needed throughout the project to
evaluate its effectiveness and to plan the ensuing work.

Meetings&Workshops
The URS Team will attend monthly progress meetings with Aspen. Because this project well be managed
from our Glenwood Springs office,we anticipate these monthly progress meetings will de held at
Aspen's offices,with some Team members attending by teleconference. In addition to meet ngs with
Aspen staff.the URS Team will prepare for and execute a public involvement program that includes two
public meetings prior to the finalization of the Draft Plan and one work session with Aspen Counc l prior
to the finalization of the Fina Plan, as shown in the Project Flowchart. Additionally,the URS Team is
prepared to meet and present draft and final reports to stakeholders such as the public, adv sory
boards, other City departments and Aspen Council.
Project Schedule
The proposed schedule is presented on the Project Flowchart in Figure 5 has been developed to
establ sh a general time frame for completion of each task. It includes monthly progress meetings, and
the council presentat ons,and workshops. The schedule however, is quite flexible. The project would
be completed sequentially(some analysis tasks will run in parallel),and the Plan built a step at a time.
Information and deliverables developed as part of each task effort will be provided to Aspen at progress
meetings for review. Draft deliverables would be submitted at the conc usion of eacn task, and review
time could be established by Aspen based on the size and complexity of the product.
