MEMORANDUM
TO: Aspen Planning and Zoning Commission
FROM: Tom Baker, Planning Office
RE: Rio Grande Final SPA and GMQS Exemption for Parking
Facility and Library
DATE: December 13, 1988
PURPOSE: The purpose of this item is to begin Final SPA for the
south portion of the Rio Grande site. As the P&Z is aware the
entire Rio Grande site has received Conceptual SPA approval,
(attachment 1). Conceptual SPA approval for the Rio Grande was a
very extensive process and included addressing many issues
normally included in Final SPA. These issues, such as traffic
impacts of the overall plan, were dealt with at the Conceptual
stage because the Final stage was envisioned to occur in
increments. The timing of these increments depended on the
funding and construction needs of the various community
facilities to be located on the site.
The entire SPA process is a four step review process with two
public hearings. The community facilities which are currently
requesting Final SPA approval are the parking facility and the
Library. Final SPA is a ,two step process with P&Z and City
Council, the first step with P&Z is a public hearing.
APPLICANT'S REQUEST: Technically, the P&Z has two applications
to review, the City sponsored parking facility and the Library
Board sponsored Pitkin County Library. These applications were
submitted separately so as to avoid delay in processing one if
the other was submitted at a much later date. Both applications
were submitted at the same time, however, and staff agrees with
P&Z's desire for concurrent review of the parking and library so
that any problems can be resolved prior to construction.
Therefore, staff is combining review of both applications into
one review. Both applicant's are requesting Final Development
Plan approval and Exemption from the Growth Management Quota
System as an Essential Community Facility.
INTRODUCTION: The developments being proposed for this SPA area
are a parking facility and library. The parking facility
development includes a 420 space parking facility built into the
hillside on the south portion of the Rio Grande, a 4,000 sq ft
transportation center for early ticket and baggage check -in for
the airlines, and arrival and departure of regional bus service
(Greyhound); a Civic Plaza on top of the parking facility; a
transit shuttle route for either bus or trolley; improved surface
parking north of the parking facility; a new access road
connecting Mill and Spring Streets; and landscaping throughout
the area being developed. The Library development includes a
22,000 sq ft library structure with landscaping.
City Council granted Conceptual SPA approval with the adoption of
Resolution 37, Series of 1988, (attachment 2). This memorandum
will focus on the conditions identified in this resolution and
the review standards in the code for Specially Planned Areas and
GMQS Exemption. Please refer to your Conceptual SPA review
packet if general information regarding zoning, ownership or
conceptual description on the Rio Grande is needed. Staff will
bring a copy of the review packet for Conceptual SPA to the
meeting.
REFERRAL COMMENTS: The following referral comments are combined
as attachment 3.
Housing Authority - No issues with either application.
RFTA - General Manager, Bruce Abel is concerned that the shuttle
route along the east side of the parking facility is too steep
and has a turn radius which is too tight. Additionally, Bruce
feels there is inadequate distance between the Bleeker alley/new
access road intersection and the shuttle route/new access road
intersection. No issues with the Library.
Leisure Services - Director Bill Efting indicates that the
original employee generation of .5 full time equivalent (FTE) for
maintenance of the Plaza and surrounding area was understated.
After further review of maintenance requirements the Parks
Department will need 1 FTE employee. Bill also indicated that
the street trees between the new access road and the playing
field were unnecessary. No issues with the Library.
Fire Marshall - All fire issues are addressed for both projects.
Water Department - Water Superintendent, Jim Markalunas had the
following comments: y
Parking Facility -
Replace the 8" cast iron pipe with ductile iron pipe and relocate
it within the new Spring Street alignment so that if it ever
ruptures it is not under the new parking facility.
We assume that the sprinkler system will be supplied by a 4" or
6" fire line lateral into the parking facility.
A utility plan be submitted to the Water Department for review
and approval prior to approval of Final SPA.
2
Library -
It is assumed that a 4" or 6" fire line is being installed for
the sprinkler system.
It may be advantageous to tap into the 6" main on Mill Street at
a location other than at the alley.
Aspen Consolidated Sanitation District - District Manager, Bruce
Matherly had the following comments:
Parking Facility -
Need more information to approve the project to sanitation.
Need to see utility cut sheets to see how collection lines will
be raised or lowered.
All manholes must be raised and lowered according to district
specifications.
A five foot cover must be kept over collection lines.
We would not recommend connecting the inside floor drains to the
proposed storm water retention area due to potential impact on
the Roaring Fork River. If they are tied into District's system,
then approved oil and sand interceptors will be required. We
will need to know the total fire sprinkler flow rate and how
applicant will handle ice and snow pack within the parking
structure. If the floor drains within the structure are tied
into the District's system, then the openings for access to the
facility must be designed so that any form or source of surface
runoff or groundwater cannot enter.the facility.
Library
Roof downspouts, exterior foundation drains, areaway drains, or
any other source of surface runoff or groundwater cannot be
directly or indirectly connected to the sanitary sewer.
Engineering Department - Elyse Elliott made the following
comments:
Parking Facility -
New street should be called Hallam.
Sidewalks or improvements on the right-of-way must comply with
Streetscape Guidelines.
All utilities should have a sign off block on the utility plat.
3
Alley width should be 201, the steep grade should be removed and
the alley should remain open for two-way traffic.
Informational and directional signage will be needed for the
parking facility.
If possible parking and circulation should be maintained during
construction. Perhaps the playing field can be used for
temporary parking.
A drainage plan, survey and utility plan will be needed.
Library -
A utilities plat and sign off blocks for all utilities will be
required.
The alley would be more appropriate for service vehicles than
combining service vehicle access with access to the parking
facility.
The size of the dumpster area should be determined by the
Engineering Department and BFI. Access to this area should be
through the alley.
The Library should provide its own parking on site, perhaps 30
spaces.
The Engineering Department must approve the drainage plan.
Environmental Health - Director Tom Dunlop made the following
comments:
Parking Facility -
A fugitive dust control plan will be required for the parking
facility and the library.
The applicant must apply for an Air Pollutant Emission Notice.
Information should be provided which illustrates that any parking
facility ticket booth attendant will work in a healthy air
quality environment. Tom recommends that information be provided
which demonstrates that potential attendants will be exposed to a
maximum of 31 ppm of carbon monoxide or lower, if possible. The
31 ppm carbon monoxide figure is an adjusted figure based on the
facility's location at 8,000 feet above sea level.
The designers of both structures should be aware of where exhaust
vents and fresh air intake vents are located so that fresh air
contamination does not occur. Additionally, vents may be the
source of noise and vibration which may adversely effect adjacent
4
non parking spaces.
The Environmental Health Office should be contacted if
contaminated soils are encountered during excavation.
Library -
The applicant shall provide a fugitive dust control plan.
The Environmental Health Office should be contacted if
contaminated soils are encountered during excavation.
STAFF COMMEEWS: Staff comments will be based first on the
conditions of Conceptual SPA approval listed in Resolution 37,
Series of 1988 (attachment 2) and then on review standards in
Sec. 7-804 (B) of the Municipal Code.
Conditions to be addressed as part of conceptual approval.
1. The City and County should agree to amend the 1982. Land
Exchange Agreement in order to avoid future confusion
regarding uses on the Rio Grande site. If the library is
not located on the Oden area of the site, then the Arts
group requests that the site be retained for a Performing
Arts Center.
Response - Negotiations are in progress. The City will meet on
this issue prior to the P&Z's meeting. Staff will summarize
Council's comments.
Conditions to be addressed at precise plan stage.
Condition
1. The applicant(s) shall submit a site plan, landscaping plan,
building design plan and building design techniques which
illustrate how the development compliments or enhances the
neighborhood. Plans for mitigation of impacts caused by the
Spring Street extension on the surrounding neighborhood
(ie., Oklahoma Flats) should also be presented. All plans
submitted shall comply with the requirements of Article 7.,
Division 8, Specially Planned Area, of the Aspen Land Use
Regulations and shall be consistent with the representations
of the approved Conceptual Plan.
Response for Parking Facility - The site plan is generally
acceptable, however, there are several areas of concern.
One of the advantages of moving Spring Street to the north
was to create a building site north of the Jail, perhaps for
a courthouse annex. The combination of the Bleeker alley,
shuttle corridor and surface parking lot have compromised
this potential. The architects have indicated that these
5
are all moveable elements and therefore the building site
potential still exists. The P&Z should consider removing
the Bleeker alley.
The turning radius and the grade of the shuttle route on the
east side of the parking structure seems inappropriate for
buses or trolleys.
The shuttle bus turnaround at the north end of Galena Street
is unnecessary.
The application fails to mention that the shuttle route will
function for both buses and trolleys.
The delivery vehicle circulation does not work for Caps, it
will be necessary to redesign the surface parking and curb
location in this area.
The width of the shuttle corridor along the east side of the
parking facility is 121. This width is not adequate for
shuttle traffic, as well as bicycle and pedestrian traffic.
Staff suggests that the corridor be widened or that a
bicycle/pedestrian path be located adjacent to the shuttle
corridor.
The Oklahoma Flats area will be impacted by traffic noise on
the new access road. The applicant indicates that this road
will be bermed and landscaped to buffer Oklahoma Flats.
Staff suggests more information is needed to determine how
effective this landscaping will be.
In terms of the landscape plan,
neighborhood will benefit.
maintenance associated with the
road and recommends that they be

it is staff's opinion that the
Staff is concerned about the
plantings along the new access
low maintenance or automatica4ly
In terms of building design plan and building design techniques,
the staff finds that the parking facility is a very unobtrusive
structure, hidden on three sides either by topography or the
library. The critical facade, the north facade, is stepped back
into the hillside so that the one story, pedestrian scale
transportation center effectively masks the parking facility.
The roof of the parking facility has been designed as a civic
plaza which also functions as a future office building site.
Staff does, however, have a number of design related concerns.
The Transportation Center roof has a north slope which will shed
snow and ice onto people using the facility, this must be
resolved. The Transportation Center roof needs to be punctuated
with architectural elements (perhaps dormers) to break-up the
stark horizontal aspect of the design. The open area behind the
9
Transportation Center roof exposes a portion of the fourth
parking level. In staff's opinion this area should be partially
protected from the elements so that snow removal is not a
problem. Parts of the ventilation system are adjacent to the
Library, in staff's opinion these should be moved away from the
Library and hidden in the landscaping. Pedestrian access across
the Plaza should attract use of the library entrance on the
Plaza.
Response for the Library - In terms of site planning, the Library
is generally located on the Oden parcel. The designers have
attempted to leave 33 percent of the site in open space. It is
staff's opinion that providing this amount of on -site open space
is unnecessary given the fact that the Library is part of the Rio
Grande Plan and this Plan has significant open space areas along
the river and playing field areas. It is staff's opinion that
the Library should use the entire Oden parcel as effectively as
possible to produce an attractive community building. Further,
by utilizing the entire parcel, the designers can better site the
Library on Mill Street. This will help achieve one of the
Councils goals, that is an active and interesting pedestrian
environment along the east side of Mill Street.
In terms of the landscape plan the staff finds that the
streetscape of Mill Street will be enhanced.
In terms of building design plan and building design techniques,
the staff has several concerns. First, staff is concerned that
the Library's orientation will not help attract people to the
Civic Plaza. The Library should be designed to have attractive
and equal entries both on Mill Street and the Plaza. Staff is
also concerned that the portion of the library which is adjacent
to Mill Street is also the most imposing in terms of height. In
staff's opinion if the library's proposed open space is used as
part of the building site, then not only will the entire
structure be sited along .Mill Street, creating potential
pedestrian interest, but the entire facade may be kept more
pedestrian. Additionally, use of the library's open space will
allow the library's designers to step back the north facade of
the structure. In staff's opinion the north facade is too
imposing and may have a negative effect on the stepped back
design of the parking facility. In discussing this point with
the designers they argued that Caps effectively provided the step
back to the library. This is going to be a discussion point at
the meeting, but it is staff's opinion that the visual impact of
north facade and the buildings northwest corner should be
reduced.
Condition
2. The following environmental studies and mitigation plans
shall be prepared to the satisfaction of the Environmental
Health Department:
7
a. Air pollution resulting from the starting of
automobiles in and mechanical ventilation of the
parking facility.
b. Water pollution hazards as a result of runoff from
impervious surfaces and the use of chemical snow
melting substances.
C. The loss of any storm water detention areas.
Response - Environmental Health has requested additional air
quality information for people working in the parking facility,
see referral comments. The parking facility will use the
existing storm drainage system and will size the ponds and
provide the necessary baffles to ensure that pollutants in the
runoff do not enter the river. There will be no loss of storm
water detention areas.
It is not clear how runoff from the library site will be handled.
An approved drainage plan is required by the Engineering
Department.
Condition
3. The City shall maintain the alley for fire protection
purposes.
Response - The alley -will be maintained for fire protection.
Condition
4. The parking structure shall be sprinklered.
Response - The parking facility has been designed to be
sprinkled.
Condition
5. Any downtown shuttle should service the Rio Grande site,
Post Office, pedestrian access points to the parking
facility and Rio Grande recreational and cultural areas, as
well as important activity centers in the downtown.
Response - RFTA has agreed to this condition.
Condition
6. The applicants shall provide to the satisfaction of the
Engineering Department the following:
a. A drainage plan.
b. A full survey with title blocks, a list of easements
and encumbrances.
C. An overlay of the survey showing utilities (this should
be signed by each utility).
Response - This must be completed prior to final approval.
Condition
7. The applicants shall work with the City and private
utilities to develop an acceptable utilities plan.
Response - This must be completed prior to final approval.
Condition
8. The following actions are encouraged as part of the
development of the Rio Grande site:
a. Increased enforcement of on -street parking requirements
in the downtown.
b. Review the existing time zone requirements for parking
in the downtown.
C. Implement the Roaring Fork Greenway Plan and the
Parks/Recreation/Open Space/Trails Plan.
d. Relocate the snowdump.
e. Relocate impound lot.
Response - The City will pursue these actions over time, however,
actions a and b are important to the success of the City's
parking program. Council has scheduled a meeting on January 16th
to discuss pedestrian improvements/auto free zones in the
downtown. The P&Z is invited.
Condition
9. The City shall develop a fee structure for the Rio Grande
parking facility which is inexpensive for the user and also
discourages use of the automobile.
Response - The City Council will deal with this condition when
the operation plan is complete. The Council has stated that a
free structure is their desire.
Condition
10. The applicants shall indicate how many employees will be
generated by the proposal and how employee housing
requirements will be addressed.
Response - The parking facility will generate either 6 or 8.6
full-time equivalent employees depending on whether the parking
facility is free or pay. The library will generate 1 additional
9
employee. Both applicants will address this issue through cash -
in -lieu payments to the Housing Authority.
Condition
11. Each applicant shall submit information for the Growth
Management Quota Exemption for essential public facilities.
Response - The applicant's have done this and it will be
discussed in a later section of this memorandum.
Condition
12. The City shall develop plans for improving the pedestrian
access between the Mall and the Rio Grande using Galena
Street. A Galena Street pedestrian corridor should be
compatible with the Mall and compatible with the Rio Grande
pedestrian system which extends through the Rio Grande to
the river.
Response - The Transportation Element has developed a plan for
the Galena Street corridor and the City Council is conducting
work sessions on pedestrian improvements and mall expansions.
Condition
13. The Library shall have the ability to expand to the east 44
feet on top of the parking facility, if their program needs
in. the long-term future justify this expansion.
Response The approved Conceptual SPA Plan identifies this
expansion potential.
Condition
14. The City and Teen Center
develop a Teen Center in
facility plaza.
group shall work together to
conjunction with the parking -
Response - The Teen Center has been located at the northeast
corner of the parking facility. This location must be approved
by the BOCC since it is partially on County land.
Condition
15. The architectural element on top of the parking facility
roof which covers- the stairwell and elevator shaft should be
relocated to an area off of the Galena Street access. This
will allow for an uninterrupted pedestrian corridor between
the downtown and the river.
Response - This element has been modified significantly, but
remains in the Galena Street corridor adjacent to the teen center
location.
10
Condition
16. The extension of Spring Street shall be 'designed so as not
to preclude the possibility of a service/gas station in
conjunction with Cap's auto.
Response - This has been accomplished.
Condition
17. The City and Library should agree on who is responsible for
what percent of general site improvements, these include,
but are not limited to utility improvements, transportation
improvements and landscaping improvements.
Response - This still needs to be clarified.
Conditions
18. The City shall experiment with a snowmelt machine as a way
of reducing the impact of the snowdump on the property.
19. The City shall reserve the area known as the Snowdump for
future Arts Usage; however, if the Library does not use the
Oden parcel, then the Arts Groups retain the right to use
the Oden site instead of the Snowdump area.
Response - Conditions 18 and 19 do not apply to these
applications.
SPA REVIEW STANDARDS: In addition to the conditions developed
during Conceptual SPA the Commission has SPA review standards -in
the code. Most of these standards have been addressed
previously and staff will only repeat significant points or
elaborate where necessary. Otherwise the text will refer to the
conditions above. Staff will again review both applications
together.
In the review of a development application for a Conceptual
Development Plan and a Final Development Plan the Commission and
City Council shall consider the following.
Standard
1. Whether the proposed development is compatible with or
enhances the mix of development in the immediate vicinity of
the parcel in terms of land use, density, height, bulk,
architecture, landscaping and open space.
Response - This standard was addressed in Conceptual SPA (land
use) and in the response to Condition 1. The important point
that staff would like to repeat is that the library's open space
area is not a significant contribution to the overall plan.
Utilizing that open space for the library structure will allow
the structure to be brought out to Mill Street which will bring
life to the street if handled properly. Further, using the open
space will allow the designers to step back the north facade and
the northwest corner of the structure so that the perceived
height and bulk are reduced.
Standard
2. Whether sufficient public facilities and roads exist to
service the proposed development.
Response - Existing and proposed public facilities and roads
exist to service the development. As part of Conceptual SPA
Leigh, Scott and Cleary conducted a traffic study and determined
that with the new access road the street system was adequate to
handle the uses proposed for Conceptual SPA.
Standard
3. Whether the parcel proposed for development is generally
suitable for development, considering the slope, ground
instability and the possibility of mud flow, rock falls,
avalanche dangers and flood hazards.
Response - The parcel is an urban parcel and suitable for
development.
Standard
4. Whether the proposed development creatively employs land
planning techniques to preserve significant view planes,
avoid adverse environmental impacts and provide open space,
trails and similar amenities for the users of the project
and the public at large.
Response - This standard was thoroughly addressed during
Conceptual review.
Standard
5. Whether the proposed development is in compliance with the
Aspen Area Comprehensive Plan.
Response - This development implements the Aspen Area
Comprehensive Plan: Transportation Element, in part.
Standard
6. Whether the proposed development will require the
expenditure of excessive public funds to provide public
facilities for the parcel, or the surrounding neighborhood.
Response - These are public projects using public funds.
Standard
7. Whether proposed development on slopes in excess of twenty
percent ( 2 0 % ) meet the slope reduction and density
requirements of Sec. 7-903 (B) (2) (b).
12
Response - This standard does not apply to this urban site.
Standard
8. Whether there are sufficient GMQS allotments for the
proposed development.
Response - Both projects are public facilities and are requesting
Growth Management Quota System Exemptions.
GROWTH MANAGEMENT QUOTA SYSTEM EXEMPTION FOR THE CONSTRUCTION OF
ESSENTIAL PUBLIC FACILITIES: Section 8-101 (C) (1) (b) states
that
"...Development shall be considered an essential public
facility if it serves an essential public purpose,
provides facilities in response to the demands of
growth, is not itself a growth generator, is available
for use by the general public, and serves the needs of
the City. It shall also be taken into consideration
whether the development is a not for profit venture.
This exemption shall not be applied to commercial or
lodge development.
The applicant shall demonstrate that the impacts of the
essential public facility will be mitigated, including
those associated with the generation of additional
employees, the demand for parking, road and transit
services, and the need for basic services including but
not limited to water supply, sewage treatment, drainage
control, fire and police protection, and solid waste
disposal. It shall also be demonstrated that the
proposed development has a negligible adverse impact on
the City's air, water, land and energy resources, and
is visually compatible with the surrounding area."
Staff Response - Staff will not address all of the points of this
section of the code because it would be redundant. The
applications and this review indicates that these developments
are essential public facilities which will be required to
mitigate the development's impacts. There are, however, two
areas of concern; the Transportation Center and parking for the
library.
Transportation Center: The question is whether the
Transportation Center should be exempt from GMQS even though
it can be viewed as a commercial entity. In staff's opinion
the Transportation Center should be exempt from GMQS because
it is an asset to the community's transportation system,
particularly the Airport. The function of the
Transportation Center is to provide the community's
residents and visitors with a place for advanced ticket and
baggage check -in, thereby helping to relieve one of the
Airlines most serious problems; that is passengers who
13
arrive at their destination prior to their baggage.
Additionally, late arriving baggage will have an in -town
facility so residents and visitors do not need to travel to
the Airport to pick up late luggage. The other function of
the Transportation Center is to provide Greyhound with an
in -town location which connects to the RFTA system.
While these functions can be viewed as commercial, the end
product is essentially better service for the air traveller
and the bus traveller. It is not likely that this facility
will increase air travel, but it may increase bus travel.
Employee generation for this facility is unknown because the
airlines may only be moving employees from the airport to
the Transportation Center. Therefore, staff recommends that
as a condition of approval the City mitigate employee
impacts at a rate of 1.5 employees per 1,000 square feet and
require the Housing Authority to do an employee audit two
years after operations begin.
LIBRARY PARKING: This issue revolves around how and where the
library will mitigate its parking impact. It is staff's opinion
that because of the unique circumstances surrounding this
development, the Library Board should concentrate its funding
resources on developing a library design which meets the
standards of the P&Z and City Council, even if that means
significant redesign, and allow the Community parking facility
to mitigate the library's parking demand. Staff supports this
opinion with the following points:
o Both the library and parking facility are public projects
using public funds.
o Staff assumes that a library in an urban location such. as
the Rio Grande will generate a significant amount of
walking, transit and multi -destination automobile trips
during the work day. During the weekend and especially the
evening, the library may generate primarily destination
trips, however, the weekends and evenings are off-peak times
when the parking facility has excess capacity.
o Library (public) funds used for parking may compete directly
with funding for other valuable community services offered
by the library or may compete directly with desired design
changes suggested by the P&Z or Council.
o The Transportation Plan found that restricted parking
spaces, i.e., "Library Parking Only", reduced the effective
utilization rate of that space by 25 percent. A condition
of approval would be that the Library Board not request
exclusive parking for library patrons in the parking
facility.
14
o The Library Board is required to fully mitigate all other
impacts.
o The Library Board can offer free bus passes or other
incentives to induce employees to walk, bike or ride
transit.
It is the staff's opinion that the Community's interests can best
be served by allowing the Library Board to focus its funding
resources on the library and for the City to focus its resources
on the parking facility. Staff would like to make it very clear
that this opinion is based on this very unique situation and
should not be construed as a policy releasing other public uses
from mitigating impacts.
RECOMMENDATION: Staff recommends Final SPA approval and Growth
Management Quota System Exemption for the Construction of
Essential Public Facilities for both the City's Parking Facility
application and the Library Board's Pitkin County Library
application with the following conditions:
Conditions for the Library
1. Prior to Council review the Applicant shall provide to the
satisfaction of the Engineering Department the following:
a. An amended drainage plan with adequate detail to

RESOLUTION NO. 37
(Series of 1988)
A RESOLUTION OF THE CITY COUNCIL OF ASPEN, COLORADO
APPROVING THE CONCEPTUAL SPA PLAN FOR THE RIO GRANDE PARCEL
WHEREAS, the City Council of Aspen, Colorado (hereinafter
"Council") has reviewed the Conceptual SPA Plan for the Rio
Grande (hereinafter "Plan") at public hearings held on September
26, October 10 and October 17, 1988; and
WHEREAS, the Aspen Planning and Zoning Commission
recommended approval of the Conceptual SPA Plan for the Rio
Grande through its Resolution No. 88-6; and
WHEREAS, in September of 1987, the Council endorsed and the
Planning and Zoning Commission adopted the Aspen Area
Comprehensive Plan: Transportation Element (hereinafter
"Transportation Plan") which identified appropriate concepts for
the Rio Grande property; and
WHEREAS, in the Spring of 1988, RFTA and the Council
retained the services of a consulting team headed by RNL Design
of Denver to develop appropriate physical and financial
alternatives for a parking facility on the Rio Grande property;
and
WHEREAS, based on their review of the Conceptual SPA Plan
for the Rio Grande property, the Council makes the following
findings:
Parking - The City Council concurs with P&Z that the
parking facility should be hidden from view and allow the
potential for other transportation related uses.
Library/Other Public Buildings - The City Council supports
the conceptual location of the library. The idea of hiding
development or minimizing the visual impact of development
may not be an appropriate concept for important public
buildings, such as the Library or the Arts buildings. These
buildings should be attractive and designed in a manner
which indicates the buildings' importance to the community.
Additionally, setting back the Library from Mill Street to
avoid the "canyon effect" which could occur because of the
location and height of the Jerome is an idea which may be
overstated. The Council finds that creating activity on the
Mill Street streetscape by setting the library close to the
sidewalk is important.
The Council finds that Galena Street will become an
important pedestrian connection between the Rio Grande
(Library, Arts, River) and the Mall/downtown area.
Therefore, pedestrian access should be improved between the
downtown and the river using Galena Street and continuing
the pedestrian treatment through the Rio Grande to the
river. In order to ensure this pedestrian flow the
architectural element on top of the parking facility roof
which covers the stairwell and elevator shaft should be
located off the Galena Street corridor.
K
Plaza - The roof of the parking facility should be a people
place with landscaping and not considered for parking. It
is important that this area be designed so that it does not
become a dead space.
Teen Center - The City Council finds that the Teen Center is
an important community function and directs staff to develop
building designs associated with the parking facility plaza.
Transit Shuttle - The Council believes that a shuttle
corridor which continues north on Galena Street along the
east side of the .parking facility can avoid some of the
traffic congestion associated with Mill Street.
Circulation - The Council finds that, if possible, Spring
Street should be located to allow for the possibility of a
gas station associates with the caps property. The
location of Spring Street should not negatively effect Cap's
business.
Snowdump/Snowmelt - The Council finds the land use impact of
a snowdump unacceptable and in an effort to reduce that
impact will install a snowmelt machine(s) in the northwest
embankment of the impound lot area.
3
Impound Lot - The Council finds that the impound lot is an
unacceptable use of the Rio Grande property and will
relocate it as soon as possible.
Revegetation - The snowdump and impound lot areas should be
revegetated to enhance the park aspects of the Rio Grande
site. This should be done as soon as the snowdump and
impound lot uses are eliminated.
NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE
CITY OF ASPEN, COLORADO:
That the Council does hereby approve the Conceptual SPA Plan
for the Rio Grande with the following conditions:
Conditions to be addressed as part of conceptual approval
1. The City and County should agree to amend the 1982 Land
Exchange Agreement in order to avoid future confusion
regarding uses on the Rio Grande site. If the library is

group requests that the site be retained for a Performing
Arts Center.
Conditions to be addressed at precise plan stage
1. The applicant(s) shall submit a site plan, landscaping plan,
building design plan and building design techniques which
illustrate how the development compliments or enhances the
neighborhood. Plans for mitigation of impacts caused by the
Spring Street extension on the surrounding neighborhood

6. The applicants shall provide to the satisfaction of the
Engineering Department the following:
a. A drainage plan.
b. A full survey with title blocks, a list of easements
and encumbrances.
C. An overlay of the survey showing utilities (this should
be signed by each utility).
7. The applicants shall work with the City and private
utilities to develop an acceptable utilities plan.
8. The following actions are encouraged as part of the
development of the Rio Grande site:
a. Increased enforcement of on -street parking requirements
in the downtown.
b. Review the existing time zone requirements for parking
in the downtown.
C. Implement the Roaring Fork Greenway Plan and the
Parks/Recreation/Open Space/Trails Plan.
d. Relocate the snowdump.
e. Relocate impound lot.
9. The City shall develop a fee structure for the Rio Grande

generated by the proposal and how employee housing
requirements will be addressed.
11. Each applicant shall submit information for the Growth
Management Quota Exemption for essential public facilities.
12. The City shall develop plans for improving the pedestrian
access between the Mall and the Rio Grande using Galena
Street. A Galena Street pedestrian corridor should be
compatible with the Mall and compatible with the Rio Grande
pedestrian system which extends through the Rio Grande to
the river.
13. The Library shall have the ability to expand to the east 44
feet on top of the parking facility, if their program needs
in the long-term future justify this expansion.
14. The City and Teen Center group shall work together to
develop a Teen Center in conjunction with the parking
facility plaza.
15. The architectural element on top of the parking facility
roof which covers the stairwell and elevator.shaft should be
relocated to an area off of the Galena Street access. This
will allow for an uninterrupted pedestrian corridor between
the downtown and the river.
16. The extension of Spring Street shall be designed so as not
to preclude the possibility. of a service/gas station in
conjunction with Cap's auto.
17. The City and Library should agree on who is responsible for
what percent of general site improvements, these include,
but are not limited to utility improvements, transportation
improvements and landscaping improvements.
18. The City shall experiment with a snowmelt machine as a way
of reducing the impact of the snowdump on the property.
19. The City shall reserve the area known as the Snowdump for
future Arts Usage; however, if the Library does not use the
Oden parcel, then the Arts Groups retain the right to use
the Oden site instead of the Snowdump area.

<:f � -
We have reviewed the application for the library SPA, as submitted as it
relates to water supply, and we have noted the applicants reference on
page 5 to an existing tap. We will check our construction records to
determine if this tap exists, and can be located. However, it might be more
advantageous to tap the 6 main on Mill St. at an new location, particularly
if the existing tap cannot be located. Reference is made to a fire sprinkler
system. Therefore, it is assumed a 4" or 6" fire line will be needed. There
is sufficient capacity in the existing distribution system to provide water
service for this proposed use. The Water Dept. will work with the
applicant in locating any existing utilities, and in developing an acceptable
utility plan for the property to be served.
ASPEN WATER DEPARTMENT
TO: Tom Baker
FROM: Jim Markalunas, Water Superintendent
SUBJECT: Rio Grande: Final SPA, Parking Facility
DATE: 11-30-88
--------------------------- ----------------------------------
The Water Dept. reviewed the application as it pertains to water
service, ref. pg. 24, 31, 35a, & 37. Due to the smallness of the drawing
submitted by the applicant, it is difficult to determine what, if any, water
improvements are involved in the SPA plan.
We wish to note, there is an existing water line of 8 cast iron pipe, as
,shown on the utility plan. In view of the fact that there will be extensive
development in the area of the existing water line for the outdoor parking,
it is the recommendation of the Water Dept. that this cast iron water main
be replaced with ductile iron pipe, and relocated within the new Spring
Street alignment, so as to remove the possibility of having this main
rupture under expensive new parking facilities.
It is the recommendation of the Water Dept. concurrent with this
development, that a new fire hydrant be installed in a designated spot as
deemed appropriate by the Fire Marshall's office.
Reference is' made in the application to a fire sprinkler system. We assume
that the sprinkler system will be supplied by either a 4 or 6" fire line
lateral into the interior parking structure.
In respect to the domestic water supply, there is sufficient existing
capacity to provide service. The Water Dept. recommends, prior to any
final development plans, that the applicant submit a utility plan for our
review and approval as suggested under item 7, page 31.

The District has sufficient line and treatment capacity to service this
project at this time. We will need more information from the applicant in
order to approve the project to sanitation. We will need to see utility
cut sheets to see how our collection lines will be raised or lowered.
All manholes must be raised and lowered according to District specifications
(ie.less than 1 foot by risers and greater than 1 foot by barrel sections).
A five foot cover must be maintained over our collection lines or the
lines we need to be relayed. This could effect our lines in Galena St.,
the alley behind Central Bank, Mill St., the parking area south of the
project, and lines in the Spring St./Eagles club area.
We would not recommend connecting the inside floor drains to the proposed
storm water retention area due to the potential impact on the Roaring Fork
River. If the applicant decides to tie these into the Districts system,
then District approved oil and sand interceptors will be required. We
will also need to know the total_. fire sprinkler flow rate and information
describing how the applicant will control ice and snowpack within the
parking structure. Finally,.if the floor drains within the structure are
tied into the Districts system, then the openings for access to the facility
must be designed so that any form or source of surface runoff or groundwater,
cannot enter into the facility.

From: Elyse Elliott, Engineering Department ,
Date: December 1, 1988
Re: Rio Grande Parking Facility
After reviewing the above application, the Engineering Department
has the following comments:
Spring Street extension - Will the street and sidewalk be built
with the 1/4% tax available for the parking facility? Can there
be parallel parking along both sides of Spring Street, especially -
in front of the Obermeyer Building? If this were being proposed
by a private developer, we would require that all right-of-way
improvements be bonded, should we consider this.? This street
should probably be renamed Hallam.
Sidewalks - Any new sidewalks or improvements on the right-of-way
must comply with our Streetscape Guidelines. It would'be nice to
have a sidewalk along the transit route from Spring Street to
Galena Street.
Utilities - It appears that all necessary utilities are close to
this project. We would like to see a sign off block by all the
utilities on the utility plat to verify the location of their
utilities.
Transit route - Presently, this is to accommodate RFTA buses or
trolleys only, but should we construct this with a greater width
to accommodate cars in the future if the congestion becomes too
great at Spring and Mill streets? Will this route be one-way?
Alley - We're pleased that the alley will remain two-way. We
would not support one-waying of this alley, as there will
continue to be alot of truck and banking traffic in the alley.
The steep grade in the alley should be leveled and the width
should be 201.
Signage - The application should address the signage needs that
this project will need. We will have to direct vehicles down
Mill and Main streets to the garage and instruct them on ingress
and egress. The "loop" in the alley should be signed to minimize
the confusion.
Downtown Parking - The application states that it will be
necessary to review existing time zone requirements for downtown
parking. The Engineering. Department will work with the Police
Department to re -assess the downtown needs in light of the new
parking garage. However, we must bear in mind that this parking
garage will not be the panacea to all of Aspen's parking
problems. I'm sure that downtown parking will still be congested
at times.
Snowdump - A snowmelter is already being constructed in the
northwest embankment of the impound lot area that should be
functional this winter. This is in agreement with the
requirements of the application.
Galena Street pedestrian corridor - Will this plan also receive
funding from the tax increase? Any plans across Main Street must
be approved by the Department of Highways.
Drainage - The plans for this look good so far. We must maintain
the historic flows in the area and make sure that no water seeps
into or stays in the garage.
Municipal Structure - The parking facility should be constructed
to accept this structure in the future. Heavy supports -should be
put in place at this stage.
Funding - We should be clear on what aspects of this project will
be paid for by the tax increase.
Construction Logistics - We would like to see parking and
circulation maintained while the garage is being built. Would it
be possible to use the ballfield for parking during this time?
Engineering Requirements - We concur with the application that we
will need a drainage plan, survey, and utility plan. The
Engineering Department would also like to offer our services on
any pertinent issues such as utilities, lighting, road work,
bidding and construction coordination.

Re: Pitkin County Library, Rio Grande Final SPA
The Engineering Department has the following comments on the
above application:
Utilities - All utilities needed to serve this project appear to
be in close proximity to this project. The Library should work
with the Parking Garage to coordinate the extension of utilities
and share the costs. As noted in the application, the
Engineering Department will require a plat of all utilities, with
a sign off block for each.
Service Vehicles - Why does the Library have a separate entrance
and exit for service vehicles? This conflicts with other
vehicles entering the Parking Garage. It seems that the service
vehicles for the Library could use the adjacent alley, since this
is the function of 'alleys. The alley in back of the Library .
should be regraded.
Solid Waste - The size of the dumpster area should be determined*
and approved by the Engineering Department and BFI. Access to
this area should be through the alley.
Parking - We don't believe that the parking need for the Library
should be provided by the Parking Garage. It has not yet been
determined whether the Parking Garage will charge for parking or
not, and parking for the Library should be free. We don't see
why the Library couldn't provide at least half, thirty, of their
required , spaces on site. At their present site, parking for the
Library. is very tight and it is in a area that has low parking
demand. We feel that the Parking Garage will be heavily used,
and therefore, the Library should provide it's own parking.
Drainage - The application states that the drainage system will_.
be design to meet historic runoff levels, and that the -
Engineering Department will be provided with an approved drainage
plan. This meets our requirements for this category.
Survey - As the application states, the Engineering Department
will be provided with a full survey of this project.

MEMORANDUM
DATE: December 9, 1988
TO: Tom Baker, City/County Planning Office
FROM: Bruce A. Abel, General Manage
RE: Rio Grande Parking Facility
Rio Grande Pitkin County Library
We have reviewed the above -referenced development applications
which have been submitted as part of the Final SPA process for the
Rio Grande property. ,Our comments tend to -pertain primarily to
the proposed parking structure as the proposed library has very
little, if any, impact on RFTA's operation.
The areas of RFTA concern regarding the proposed development ap-
plications are as follows:
1. We are concerned..that the grade of the proposed shuttle/ped-
estrian/bike path be manageable given winter street/driving
conditions. We would hope that the grade would be no more
than 7% maximum and would prefer no more than 5%. In ad-
dition, the issue of maintenance, i.e..: snowplowing of this
shuttle path, is not addressed in the application. This path
needs to be wide enough to be easily and adequately maintain-
ed as well as wide enough to operate an eight (8) foot wide
vehicle with a 6-8 inch wide ski rack in a safe fashion given
the other proposed uses of this path. We would prefer a
dedicated right-of-way.;
2. The turning radius of the traffic circle at the end of Galena
and the intersection of this circle and the shuttle path
needs to be sufficient to insure maneuverability of RFTA
shuttle vehicles. 'The turning radius should be no less than
thirty-five (35) feet for design purposes;
3. The distance between the intersection of the Spring Street
extension and Bleeker alley and the Spring Street extension
and the shuttle path needs to be sufficient to avoid con-
flicts;
4. The application makes reference in several places to the
opinion that if there are no parking fees charged at the Rio
Grande facility then it would not be necessary to undertake a
