RE: Lodging Incentive Program
REQUEST OF COUNCIL: Staff requests Council direction to move forward with code amendments
for a lodge incentive program. Staff believes the discussion has reached a point where it should move
into the public realm through public hearings. Staff will continue to refine the proposals and will
continue public outreach as the code amendments work their way through public hearings. If Council
gives the go-ahead, staff will present a Policy Resolution at the May 27th regular Council meeting.
BACKGROUND: One of City Council’s Top Ten Goals is to “Implement an incentive program for the
short-term bed base.” This goal came about partly because of the recognition that Aspen has lost a
significant amount of our bed base since the 1990s. Between 1995 and 2006, the city lost 27% of the
bed base – including both traditional hotels as well as condominium rentals.
Staff began working on this goal by gather existing conditions information and working extensively with
the lodging and condominium community. Through those efforts, the City learned that over 40% of our
bed base is in condominium rentals, that more families are visiting and they demand larger units, and
that the city process is unwieldy and unpredictable. We’ve also learned through the 2013 lodging
economics study by EPS, that basic free-market units that are not required to be in the rental pool
continue to be a critical economic engine for lodge upgrades and redevelopment.
Staff has met with City Council in a number of work sessions since the fall of 2013 and received
direction on key aspects of a potential lodge incentive program. Staff has also worked extensively with
the lodging and condominium community to ensure the incentives proposed will have a positive impact
on lodging in Aspen.
In preparation for this work session, staff has continued to meet with representatives from the lodging
and development communities to determine if the potential changes will, in their opinions, result in
investment and improvements to the bed base. Staff has also met with the Planning and Zoning
Commission and Historic Preservation Commission to gain feedback on the potential direction. Staff
will summarize these comments in the presentation at the work session.
GENERAL: As part of an incentive program, staff is proposing the following three (3) distinct use
categories:
• Lodge –A building or parcel with individual units that allows periodic overnight short-term
rental to the general public for a fee, can have multiple ownership structures, and includes guest
P1

amenities, such as a front desk, concierge services, pool/hot tub, gym facilities, meal service,
shuttle services, ski storage, etc. Occupancy by one person or entity is limited to 30 consecutive
days and 90 days in one calendar year. (This is an existing type of use.)
• Vacation Residences – An individual free-market residential dwelling unit within a multi-family
or lodge project that allows periodic overnight short-term rental to the general public for a fee. A
Vacation Rental Unit complex may include guest amenities typically found in a lodge.
Occupancy by one person or entity is limited to 6 months in one calendar year, and the unit must
be available for short-term rental the remainder of the year. (This is a new type of use.)
• Free-Market Residential Unit - An individual free-market residential dwelling unit within a
multi-family or lodge project that is not required to allow periodic overnight short-term rental to
the general public. Occupancy is not limited. (This is an existing type of use.)
In the past, staff has referred to the Vacation Residences as condominium units and hybrid units. The
intent is to encourage wholly-owned residential units that are available for rent throughout the year,
much like the units at the Viceroy Snowmass, or the Gant. Staff believes these are the types of free-
market residential units Council has expressed interest in promoting as part of a lodge incentive program
because they contribute to the bed base. Staff continues to believe some assurances that there units will
function as short-term rentals is needed.
DIMENSIONS: There are a number of dimensional changes staff proposes as part of a Lodge
Incentive Program. These are outlined briefly below and in the zone district sheets attached as Exhibit
A.
Height: Throughout the outreach, staff has heard that some additional height is needed to justify
investment in an existing lodge or to make a new lodge work. In general, feedback from Council and
from the community has indicated height for a fourth floor for properties closer to the mountain may be
appropriate, while lower heights in neighborhood lodges is most appropriate. Staff proposes high
increases in the Residential Multi-Family (RMF) zone and the Lodge (L) zone, and proposes height
limits in all other zone districts remain the same.
• For the RFM zone, staff proposes a height increase from the current 25-32 feet to 25-36 feet,
depending on the density of the project (higher heights if more units are provided).
• For the Lodge zone, staff proposes maintaining the current limits of 28-40 feet for two and three
story buildings, and allowing a fourth floor only through a Planned Development review. Staff
is suggesting no set height limit for the fourth story to allow applicants and City Council
flexibility in addressing unique site and project characteristics through the Planned Development
review.
Unit Size: When staff met with City Council in March, Council expressed a desire to include unit size
limitations for lodge units, vacation residencies, and free-market units. The proposed unit size
limitations, which would be the same across all zone districts, are based on outreach with the lodging
and condominium communities, as well as the city-commissioned studies related to unit demand.
P2

• Lodge Units – 1,000 square feet, which can be expanded to 2,000 square feet through the
landing of a TDR. This represents a new code limitation. Staff believes it is important to
include a size limit on lodge units that relates to the market demand analysis conducted in the
city studies.
• Vacation Residences – 1,500 square feet, which can be expanded to 2,500 square feet through
the landing of a TDR and Special Review approval. This represents a new code limitation
because it is a new use and is consistent with the existing free-market residential unit size limits.
• Free-market Residential units – 1,500 square feet, which can be expanded to 2,500 square feet
through the landing of a TDR. This is the same base limitation that is currently in the Lodge
and RMF zones, and the same maximum limitation in the commercial zones.
There has been discussion that allowing some increases to unit sizes and allowing the combination of
units might help some units be more rentable or enter the short-term rental pool. Staff has some
concerns that significantly increasing allowable unit sizes could have the opposite effect, and could
result in a unit functioning more like a single-family home than a short-term rental unit. This concern
has been echoed by some condo experts and by the Planning and Zoning Commission. As such, staff
proposes that lock-offs, which would allow flexible unit configurations, be permitted, but that the largest
combination of lock-offs associated with any one unit be limited by the unit size caps listed above.
In the proposal above, staff has included the landing of TDRs as a way to increase unit sizes. The use of
TDRs continues to be a high priority for staff. The program, which preserves historic resources by
removing development pressures from historic properties, relies on demand for TDRs. Staff
recommends incorporating TDRs to the extent possible in order to continue the success of this historic
preservation program.
Floor Area: Staff proposes to maintain the existing overall floor area caps in all the zone districts, with
some minor changes in use categories. For instance, increasing the allowed lodge floor area in all zone
districts to the same as the overall cap to make it easier for a property owner to build an entire lodge
project.
Free-Market Residential Uses: As mentioned above, staff’s outreach has indicated free-market
residential uses help fund lodge redevelopment. There have also been discussions on how much
residential space should be permitted within lodge projects. If the city’s goal is to encourage short-term
rentals in vacation rental units and lodge units, those uses should be prioritized in zoning.
Currently the amount of free-market residential space allowed is based on the size of the lodge units –
the smaller the average lodge unit the more free-market residential floor area is allowed. The following
table summarizes the current allowances in the Lodge Zone District:
Average net livable area of
individual lodge units on the
parcel
Free-market residential FAR as a
percentage of total lodge unit and
affordable housing net livable area
Greater than 600 square feet 5%
600 square feet 15%
P3

May 20, 2014 Council Work Session – Lodging
Page 4 of 8
500 square feet 40%
400 square feet 50%
300 square feet or less 60%
Rather than tying free-market residential floor area to lodge unit size, staff proposes comparing lodge
net livable to free-market residential net livable so it’s more of an apples-to-apples comparison. Staff
proposes the following ratios:
Density of Hotel, Lodge, and
Vacation Units on the Parcel
Maximum free-market residential net
livable area as a percentage of the
total Hotel/Lodge/Vacation unit net
livable area
Total Hotel/Lodge/Vacation units
is less than one unit per seven-
hundred-and-fifty (750) square
feet of Net Lot Area.
25%
(can be increased by up to 15% through
Planned Development Review)
Total Hotel/Lodge/Vacation units
is one or more units per seven-
hundred-and-fifty (750) square
feet of Net Lot Area.
35%
(can be increased by up to 15% through
Planned Development Review)
It is important to note that staff continues to work on these percentage and they will likely be increased.
Staff is using a basic development proforma to test various levels. In addition, staff proposes allowing
free-market residential uses only be allowed in the Lodge Zone District if they are associated with a
lodge or vacation rental unit project.
GROWTH MANAGEMENT: Staff proposes a number of changes to the Growth Management Quota
System to help facilitate lodge and Vacation Residence development.
Multi-Family Replacement Program: As was indicated in the Barriers to Condominium Development
study, one of the main hurdles to condominium upgrades is the multi-family replacement program.
Currently, if a residential unit has ever housed a local working resident it cannot be demolished or
combined with another unit without providing mitigation in the form of built units on the project site.
This location requirement has prevented many multi-family complexes from redeveloping because the
density required by the location requirement exceeds what is allowed under zoning, or is deemed as
unworkable by the complex.
Staff proposes the following changes:
1. Place time limits on the effectiveness of the program such that mitigation under this program is
not required if the Multi-Family Housing Units have been used exclusively as tourist
accommodations or by non-working residents for the past ten (10) years for properties in the
Lodge (L) zone district, and twenty (20) years for properties in all other zone districts.
2. Allow the use of Certificates of Affordable Housing Credit and off-site units to be used to meet
the requirements, rather than requiring all replacement units all be built on-site.
Lodge Mitigation: One barrier existing lodge operators and potential lodge developers indicate as a
significant hurdle for a successful upgrade, remodel, or new development, is the amount of affordable
P4

Page 5 of 8
housing mitigation required. They feel the code requirements do not match with their operational needs.
The current lodge mitigation requirements are on a sliding scale based on lodge unit sizes. The smaller
the average unit size, the less mitigation is required.
Staff recommends simplifying the system by no longer basing it on unit size, and suggests establishing a
minimum number of affordable housing units required on-site based on lodge size. Priority could be
given to a lodge manager or other staff that need to be nearby or on-call to respond to emergencies and
guest needs. Staff proposes the following changes:
1. If the project contains a minimum of one (1) lodge unit per seven hundred and fifty (750) square
feet of net lot area and participates in the City’s Lodge Incentive Program, the following
affordable housing mitigation standards are recommended:
Number of
Lodge Units
Affordable Housing Unit
Requirement
current 60% mitigation rate
would be
1 – 10 Units No Requirement 1.08 FTEs – 3.6 FTEs
11 – 25 Units 1.75 FTEs 3.96 FTEs – 9 FTEs
26 – 50 Units 3.5 FTEs 9.36 FTEs – 18 FTEs
51+ Units 5.25 FTEs 18.36+ FTEs
2. If the project contains a minimum of one (1) lodge unit per seven hundred and fifty (750) square
feet of net lot area and does not participate in the City’s Lodge Incentive Program, the following
affordable housing mitigation standards are recommended:
Number of
Lodge Units
Affordable Housing Unit
Requirement
current 60% mitigation rate
would be
Up to 2 Units No Requirement No Requirement
3 – 10 Units 1.08 FTEs 1.08 FTEs – 3.6 FTEs
11 – 25 Units 3.96 FTEs 3.96 FTEs – 9 FTEs
26 - 50 Units 9.36 FTEs 9.36 FTEs – 18 FTEs
51+ Units 18.36 FTEs 18.36+ FTEs
Lodge Allotments: One barrier for potential lodge development is the number of allotments available
in any one year. There are currently 112 lodge pillows available in any one calendar year. Each lodge
bedroom is considered to have 2 lodge pillows, resulting in the ability to add 56 total lodge bedrooms in
any one year. This represents a 1.5% annual growth rate. City Council decided to rollover 2013 lodge
allotments into 2014, so this year there are 224 lodge pillow allotments available.
Staff proposes there be no limit on lodge allotments in 2014 and 2015 as an incentive to get lodge
projects to apply under the incentive program and that every subsequent year be limited to 202 pillows.
The latest pillow count shows 10,085 pillows in Aspen, for a 2% growth rate of 202 pillows per year.
Even with this increased number, there remain concerns about this being a barrier.
Free-Market Residential Allotments: Staff proposes continuing with the 0.5% growth rate established
for free-market residential, which would be 19 units.
P5

May 20, 2014 Council Work Session – Lodging
Page 6 of 8
Vacation Residences Allotments: Staff proposes allowing a 1% growth rate for new vacation
residences, which would be 38 units.
DEVELOPMENT FEE CHANGES: The main incentives for major reinvestment will continue to be
height, affordable housing, and free-market residential use. A predictable process and lower fees are
still important and can make a big difference for projects. In previous discussions Council asked staff to
aim for a 50% reduction in “city fees.”
In order to get to 50%, larger reductions for general fund services are being proposed. This will allow
enterprise programs such as the water department to remain unaffected. Staff is recommending fee
reductions based on the level of program a lodge or vacation residence is pursuing (basic, standard,
standard plus) and whether the project contains free-market residences. Below are the suggested
reductions.
Program level w/o Residential w/Residential
Basic 50% waiver 25% waiver
Standard 75% rebate 50% rebate
Standard Plus 100% rebate 75% rebate
Staff recommends the basic projects receive fee waivers. This allows a project to simply pay less for the
permit. Standard and Standard Plus projects would be eligible for fee rebates. This would require full
payment upon permit with a payment back to the applicant over 5 years. These advanced projects would
involve a development agreement with some ongoing performance and reporting requirements. The
City would need to budget for these annual rebates.
Staff suggests a significant reduction for right-of-way encroachment and construction parking fees. This
current fee offsets service needs but is also established to encourage minimal impacts to public property,
both in physical footprint and duration. The fees can be sizeable. The reductions may be a combination
of outright fee reductions and/or a no charge period such as a season or two for free. Staff still
recommends applicants be required to make reasonable efforts to minimize footprint and duration.
NON-DEVELOPMENT INCENTIVES: While development incentives are an important part of any
incentive program, there are existing lodges that are not interested in adding rooms or doing a
redevelopment. Instead, they are interested in maintaining and improving their existing product. Staff
has worked with a number of these properties to determine different incentives that may assist them.
Staff has not evaluated the financial impact these would have to the City, but will if City Council is
interested in exploring any of these incentives.
Grants: Some small lodges have a difficult time with basic maintenance and upgrades. Grants and
loans were identified by at least four lodges as one of the main ways the city could assist them. While
there is interest from small lodges in a grant program, others in the community are not in favor of
outright grants. The concern is twofold – 1) an outright grant does not require any “investment” by the
property owner and may not be based on wise business principals. And, 2) a grant may simply postpone
a difficult business decision.

A possible better use of City funds may be to purchase a deed restriction, insuring that a lodge will
remain a lodge in perpetuity. This may require more funds up front, but may have a greater long-term
value to the community. If the Council is interested in a grant program, staff suggests matching grants
and requesting lodges show some financial argument for the investment and possibly their financial
need. The amount of grant money available would need to be budgeted each year.
Loans: A low or zero interest loan program was also identified as desirable by several lodges. The City
could establish a program for zero interest loans to assist these properties. There is much less resistance
in the community for a loan program, likely because it still requires a business-based decision. Staff
recommends this be included in the lodging incentive program. The amount of loan money available
will also need to be budgeted annually.
Amenity Evaluation Program: A number of lodges thought an evaluation by Stay Aspen Snowmass
on what amenities or services the lodge could add that would attract increased visits would be a benefit.
Others indicated they know what they need to upgrade, but funding is the primary reason they have not
done so. The City likely has a minimal role in this, but lodges implementing amenities identified in an
evaluation could get priority in any loan or grant program.
Parking Passes: Every small lodge we talked with indicated free street parking passes for their guests
would be a significant help for them. The very small lodges (15 or so units) indicated about 20 passes
per unit would help them, while the larger small lodges (50 or so units) indicated 75 passes per unit
would help them. The lodges also indicated that having parking passes that are good for smaller
increments of days (2-day passes or 4-day passes, for instance) would be helpful.
Parking in the Right-of-Way: A number of lodges felt having a few dedicated parking spaces adjacent
to the lodge would help accommodate check-ins as well as longer term parking for their guests. Many
of the small lodges have parking in front of the lodge that could be licensed to the lodge for a period of
time through an encroachment license.
Transportation: A number of lodges located in the neighborhoods as well as further down on Main
Street expressed interest in increased transit service that drops visitors closer to their doors. One idea
was to expand the cross-town shuttle service to go into the Shadow Mountain neighborhood, or to
coordinate with RFTA to have more stops on Main Street.
Pull-outs: One lodge expressed interest in adding a pull-out that would enable cars to stop at their lodge
and go in to check availability and rates. This is likely infeasible along Main Street, but could be
possible along some side streets.
Marketing: Another area of interest from the small lodges is a coordinated marketing campaign that
highlights their properties as options for travelers. Again, the City likely has little role in this, but it has
been raised a number of times so staff wanted to include it here.
QUESTION FOR COUNCIL: Does City Council support moving into public hearings to discuss
policy changes for a Lodge Incentive Program? Staff suggests this program is ready for public
vetting. Many of the policies need refinement and this is natural and desirable to happen in the context
of public hearings.

NEXT STEPS: If City Council gives the go ahead to move into code amendments, staff will present a
Policy Resolution on May 27th and if that is approved proceed directly into 1st and 2nd readings on code
language.

RE: Castle Creek/Hallam Street Connectivity Study: Project Kickoff
Worksession
SUMMARY: Staff seeks Council input and guidance regarding pedestrian, bicyclist, and traffic
safety on the Castle Creek/Hallam Street Connectivity Study.
BACKGROUND: Open Space and Trails Board members along with Engineering, Parks, and
Transportation staff have identified the Castle Creek Bridge and Hallam Street corridor as
deficient link in Aspen’s bicycle and pedestrian network. Due to topographic, property, and
geometric constraints safe travel options are limited throughout this area.
The Castle Creek/Hallam Street Connectivity Study follows the ideals of The City of Aspen Civic
Master Plan (CMPAG) adopted by City Council in December 2006. The Plan states “Aspen’s
future should be one in which the automobile plays a smaller role in people’s everyday lives.
Other modes of travel should be made as safe and convenient as possible to facilitate that
goal…the level of investment in…more and better bikeways and walkways should increase.”
During the January 7th 2014 worksession, staff and Open Space and Trails Board
members presented the Castle Creek/Hallam Street Connectivity project as a priority to
City Council. Council members directed staff to return to Council with a design contract
addressing feasibility options for this corridor. Council approved the staff recommended
professional services contract with Loris and Associates during the April 7th 2014 regular
Council meeting.
This project is currently in the data collection phase. Staff has utilized Loris and Associates
professional engineering services to gather Right of Way, property and topographic data as well
as study the constraints of the existing Castle Creek Bridge structure. Loris and Associates have
outlined their initial findings in the Hallam corridor Study – Castle Creek Bridge Draft Design
Memo (Attachment A). Due to the complexity of the structure and adjacent topography the
Castle Creek Bridge was identified as a controlling factor in the design of the corridor.

Within the context of this project there are opportunities for the City to:
Improve pedestrian safety through better pedestrian/traffic interactions, including
treatments for both vehicular and pedestrian traffic.
Improve Aspen’s East-West pedestrian and bike connectivity
Update and enhance Castle Creek Bridge connections to adjacent roadway, pedestrian,
bicyclist infrastructure.
Improve the existing bus stop location
Enhance pedestrian safety by examining existing crossings and pedestrian patterns
Improve the crossing infrastructure including ADA accessibility upgrades.
Engage the Trail and Open Space Board Members and other stakeholders during the
design process
Engage the Colorado Department of Transportation Staff and other stakeholders during
the design process
Engage the community and other stakeholders during the design process
Re-evaluate past corridor study, planning, bridge analysis and cost estimation
Provide alternatives that don’t exclude any future “Entrance to Aspen” design
NEXT STEPS: After City Council and Trails and Open Space Board input, staff will work with
the Loris and Associates team to refine graphics for the public outreach portion of the project.
The team will extend its outreach to other primary stakeholders during this period. The group
will incorporate data collected and input received during this phase into an Alternative Analysis
Report. This report will be shared with City Council in a future work session.

Design Memo -- DRAFT
Date: May 15, 2014
To: Tyler Christoff (City of Aspen)
From: Pete Loris (Loris and Associates)
Subject: Hallam Corridor Study – Castle Creek Bridge
BACKGROUND
Loris and Associates (Pete Loris and Max Condiotti) held a teleconference with CDOT Staff Bridge
(Behrooz Far and Ali Harajli) on April 30, 2014. The purpose of the meeting was to discuss how the
Castle Creek Bridge (Structure No. H-9-B) cross section could be altered to more safely
accommodate bicycle and pedestrian traffic. The bridge is currently configured with two 12 foot
lanes, two 2 foot shoulders and two 5 foot raised sidewalks (see the upper left cross section depicted
on Attachment 1). According to the AASHTO Guide for the Development of Bicycle Facilities, in order to
accommodate both bikes and pedestrians, there should be at least one 10 foot wide minimum (12 to
14 foot preferred) multi-use path crossing the bridge.
The existing Castle Creek Bridge is 423 feet long and was constructed in approximately 1963
(Attachment 2). The structure has a recent history of abutment and pier issues. It currently has a
Sufficiency Rating of 62 based on the 9/5/2012 Structure Inspection and Inventory report.
Our discussions essentially resulted in the following concerns for the project:
1. The existing bridge is over 50 years old and is nearing the end of its useful life. A new
structure added to the existing structure would run the risk of becoming obsolete if and
when the Castle Creek Bridge is replaced, although the bridge is not currently scheduled for
replacement.
2. The existing bridge has a recent history of abutment and pier rotation problems as
referred to by Messrs. Far and Haraji. Any bridge modifications should not increase the
forces on these elements. This would steer the project to options that do not add or at least
minimize the addition of loads to abutments and piers. There was not as much concern in
the teleconference over the capacity of superstructure elements.
3. The addition of new foundation elements for the widened structure could cause potential
issues with differential settlement between the new and existing structures. This would
steer the widening to a completely independent structure.
4. The addition of pier columns could require additional right-of-way because the existing
right-of-way is only 60 feet wide at the bridge.
5. The bridge widening should not preclude future Entrance to Aspen options. This is
difficult to assess because an ETA alternative has not been selected. Previously presented
alternatives will be evaluated, including the Cut and Cover Preferred Alternative Alignment
of the August 1998 Record of Decision State Highway 82 Entrance to Aspen (CDOT Project STA
082A-008.

6. Aesthetics of widened structure should be considered.
7. Although this was not specifically discussed in the meeting, the bridge is now over 50 years
old and is considered historic. Modifications to the structure will need to be approved by
the State Historic Preservation Officer (SHPO).
OPTIONS
We discussed three options for the bridge widening:
1. Add a short cantilevered section to the pier cap to accommodate the multi-use path. This
would not require additional columns and is similar to the lower middle concept depicted on
Attachment 1.
2. Extend the abutment and pier caps and add columns to the outside of the existing
bridge. This would be similar to the upper right concept depicted on Attachment 1. This is
an Entrance to Aspen (ETA) concept presented by SGM.
3. Provide a separate, independent bridge for the multi-use path.
Option 1 (Cantilevered Section) LORIS previously presented an option to widen
the bridge (lower center cross section of Attachment 1) that includes a portion of the pier cap to be
removed and a new structural system to be installed to support the multi-use path. Steel beams and
decking could be designed to accommodate the path; however, the pier cap has inadequate shear
capacity to carry the new outboard beam. The cap would need to be strengthened with a new
concrete cap that would likely need to be post-tensioned to attach it to the existing structure.
ADVANTAGES
Does not widen the bridge footprint.
Keeps multi-use path traffic close to the road and general direction of traffic.
DISADVANTAGES
May not be supported by CDOT.
Could add long-term financial responsibilities to the city depending on the terms of an IGA with
CDOT.
May have a short life based on the life of the existing bridge.
Adds stress to existing pier caps, columns and foundations.
Complicated analysis and design of an old bridge with a potentially significant number of
unknowns to be discovered during construction.
Would not work for the Reversible Lane options of ETA.
The bridge cross section is likely to not be symmetric so aesthetics could be a concern.
Bridge modifications could require historic clearances.
Option 2 (Extend Cap & Add Column) This option provides a pier cap extension
that is supported at its end by a new pier column. The new pier cap would be connected to the
existing cap as a continuous or simply-supported structure which simplifies the new load path on the
existing structure (as opposed to Option 1), although additional load will be added to the existing
structure.

ADVANTAGES
Keeps multi-use path traffic close to the road and general direction of traffic.
Provides an easier to analyze and design pier and abutment construction with potentially less
additional force on the existing substructure elements (less than Option 1).
Would work for the Reversible Lane options of ETA.
DISADVANTAGES
May not be supported by CDOT.
Could add long-term financial responsibilities to the city depending on the terms of an IGA with
CDOT.
Widens the bridge footprint possibly requiring right-of-way.
May have a short life based on the life of the existing bridge.
Adds stress to existing pier caps, columns and foundations.
Analysis and design of an old bridge with a potentially significant number of unknowns to be
discovered during construction.
Differential settlement between existing and proposed foundations could take place.
The bridge cross section is likely to not be symmetric so aesthetics could be a concern, although
potentially less of a concern than for Option 1.
Bridge modifications could require historic clearances.
Option 3 (Separate Bridge Structure) This option would construct a new multi-
use path bridge adjacent to the existing structure. The new bridge could be any reasonable structure
type, including steel truss, steel or concrete girder, arch or cable.
ADVANTAGES
The addition will have a life independent of the existing bridge.
Does not increase load and stress to the existing structure.
Eliminates the unknowns of modifying an existing old structure.
Differential settlement is not an issue because the new and existing structures are independent.
Could work for any existing or proposed ETA option if sufficient space is provided between the
existing and proposed structures.
Could have any aesthetic.
Would not require historic clearances.
DISADVANTAGES
Separates the multi-use path from the road.
Depending on what side of the existing bridge the new bridge is built, right-of-way may be
required.
RECOMMENDATIONS
Based on the above factors, the teleconference attendees agreed that the most desirable structural
alternative to provide additional multi-use capacity along the Hallam Avenue corridor is to
construct a new, independent bridge adjacent to the existing Castle Creek Bridge. This is based
on the above factors and does not consider how the separated bridge affects bicycle and pedestrian
connectivity.

Our discussion did not include costs. Costs should be considered in future analyses; however, it
is likely that modifying the existing structure would have a cost comparable to (if not greater than)
constructing a new bridge. This is because of the higher inherent cost and contingencies associated
with structural removals and construction on an old bridge. The cost advantage of a new,
independent bridge could become more apparent when life cycle costs are considered because the
new bridge would have a life expectancy of at least 50 years; whereas, the life of adding onto the
existing structure is dependent on the life expectancy of the existing bridge, which can be assumed to
be less than 20 years.
A major cost item of the separate bridge will be construction of piers that can be up to 68 feet tall.
Constructing a two or three span structure instead of copying the five span arrangement of the
existing Castle Creek Bridge would save substructure costs. If a three span bridge is considered,
spans would be approximately 140 feet long, which are within reason for girder or truss bridges.
ADDITIONAL COMM ENTS
The Hallam Connectivity Study will evaluate options that include a separate bicycle and pedestrian
structure. Once bicycle and pedestrian connectivity are evaluated and if it is deemed necessary to
have the additional bicycle and pedestrian capacity on the Castle Creek Bridge itself or immediately
adjacent to the bridge, the bridge widening would be revisited and justified using a rigorous
structural, cost and life cycle analysis. In addition, other options that include reducing existing
vehicular lane width to increase sidewalk width would be evaluated more thoroughly.
