TRANSPORTATION ADVISORY BOARD
AGENDA ITEM
MEETING DATE: June14, 2004
AGENDA TITLE:
Public hearing and consideration of a recommendation to Planning
Board on the Twenty Ninth Street Site Review Amendment Plan (Crossroads Mall
Redevelopment requested amendments to the Boulder Valley Regional Center (BVRC)
Transportation Connections Plan.
PRESENTER:
SteveDurian, Transportation Engineer
Executive Summary:
The review of the Twenty Ninth Street project for the redevelopment of the Crossroads
Mall consists of several stages. Staff reviewed a pre-application submittal for initial issue
identification in April 2003. The second stage, Concept Plan review, is a non-binding
review and comment by the community, staff, the Boulder Urban Renewal Authority
(BURA), and Planning Board. The Concept Plan Review was completed in September
2003. The final stage of review is Site Review Amendment (and Use Review) which will
include a decision by Planning Board (currently scheduled for July 7 and 8)on a site plan,
applicable conditions of approval, and amendments to the Boulder Valley Regional
Center (BVRC) Transportation Connections Plan.
Westcor, the developer of the Twenty Ninth Street site, has submitted a plan that
proposes construction of many of the critical missing connections that are shown on the
th
BVRC Connections Plan. These include the 29 Street and Canyon Boulevard
alignments as well as pedestrian and bicycle upgrades. Due to the locations of the
existing and proposed buildings and physical restrictions on the site, the developer is
proposing to amend several of the connections shown on the BVRC Transportation
Connections Plan.
BVRC Transportation Connections Plan:
Elements of the BVRC Transportation Connections Plan (BVRC TCP) are required to be
constructed or areas reserved for future construction at the time of redevelopment. If a
proposed connection is located more than 150 feet from the location shown on the BVRC
Connections Plan or if an applicant proposes not to construct or reserve a connection, the
BVRC Connections Plan must be amended. The amendment procedure outlined in the
BVRC Connections Plan requires review and recommendation by both the TAB and the
AGENDA ITEM #________PAGE________
Boulder Urban Renewal Authority (BURA) Board.These recommendations are
provided to the Planning Board for a final decision on the amendment request. City
Council will have the opportunity to call-up the decisions of Planning Board regarding
amendments to the BVRC Connections Plan.
Concept Review Summary:
The Concept Plan for the Twenty Ninth Street development was presented to TAB on
September 8, 2003. BURA and the Planning Board also reviewed the Concept Plan.
Some consistent themes Board members related to the transportation connections were:
Assure that the connections are well designed for their intended mode of
transportation
Allow flexibility in the implementation of the transportation plan
Assure that the entire site is well connected consistent with the intent of the BVRC
Transportation Connections Plan
Site Review Proposal:
The Site Review plan has five significant changes related to the BVRC Connections Plan
compared to the Concept Plan previously presented to the board:
1.A connection for bicycles, pedestrians, and vehicles through the proposed new
th
30 Street parking structure has been added to better connect the north and south
ends of the site
th
2.An access drive for bicycles, pedestrians and vehicles to Arapahoe between 29
th
and 30 Street has been added to the plans.
th
3.29 Street on-street bike lanes and sidewalks have been added in lieu of a multi-
use path shown on the BVRC TCP
4.Several of the on-site multi-use paths have been changed to narrower sidewalks,
however these are landscaped and better distributed throughout the site.
5.On-street bike lanes along Arapahoe Avenue are specified to be removed
Westcor’s proposed Twenty Ninth Street Site Review plan would change or remove
several connections shown on the BVRC Connections Plan. These proposed changes are
different than those proposed on the concept plan due to the evolution and greater detail
included on the site review plan. Staff recommendations for each of these proposed
amendments are included under the Staff Analysis and Recommendation section below.
Specific requested amendments include:
A.Removal of On-Street Bike Facilities on Canyon (consistent with TMP)
B.Removal of On-Street Bike Facilities on Arapahoe
th
C.Replacement of multi-use path along 29 Street with sidewalk and on-street bike
lane
D.Removal of a portion of north-south Secondary Vehicular Connections between
thth
29 and 30 Streets south of Canyon
th
E.Removal of a portion of a north-south Secondary Connection between 28 and
th
29 Streets south of Canyon
AGENDA ITEM #________PAGE________
F.Alterations to alignments of Multi-Use Paths internal to the site and changes to
several multi-use paths to pedestrian sidewalk connections
The role of TAB is to address the merits of the proposed modifications to the
transportation connections only and not other aspects of the development proposal such
as parking lot configurations, architecture, building locations, etc. BURA and Planning
Board will consider TAB’s recommendations at meetings in June and July.
Staff Analysis and Recommendation:
The plans that are being presented to TAB are from the Site Review package submitted to
staff, BURA, and Planning Board. Westcor’s site plans and the BVRC Connections Plan
are attached to this document with notes showing the proposed amendments.
A) Removal of On-Street Bike Facilities on Canyon
Currently there are no bike lanes on Canyon west of the Twenty Ninth Street site.
Proposed bike lanes on Canyon have been removed from the Transportation Master Plan
(TMP) with the recent update of that plan. Removal of bike lanes on Canyon within the
Crossroads site would be consistent with the TMP recommendation.
Advantages:The most significant advantage to removing bike lanes along Canyon is that
they would not function well with proposed head-in angled parking. Head-in angled
parking along a street frontage increases the high-turnover parking in front of retail
buildings which makes the retail more viable. However, head-in parking creates more
potential conflicts for bikers along this street.
Disadvantages:The removal of bike lanes along Canyon would eliminate an exclusive
bicycle facility along Canyon. This disadvantage should be considered in the context that
the bike lanes would only extend two blocks through this site and not beyond the site.
Staff recommendation: Due to the marginal value that a bike lane would have on this
portion of Canyon without bike lanes elsewhere on this street, staff recommends that
these be removed from the BVRC Connections Plan, consistent with the Transportation
Master Plan.
B) Removal of On-Street Bike Facilities on Arapahoe
Bike lanes along Arapahoe east of Folsom are shown on the BVRC Transportation
Connections Plan and on the Transportation Master Plan. However, it is unlikely that
bike lanes will be constructed along other portions of Arapahoe due to the locations of
bridges, existing privately-owned buildings and improvements, mature trees, and other
obstructions. With the elimination of bike lanes from the BVRC Connections Plan, there
would still be a multi-use path on both sides of Arapahoe in the vicinity of the Twenty
Ninth Street development and elsewhere along Arapahoe.
th
Advantages:The primary advantage to the 29 Street development’s property is that it
allows flood wall and grading to be located 5 feet further to the south than it would with
AGENDA ITEM #________PAGE________
bike lanes. This would, in turn, result in less steep grading on the south end of the site.
Removing the requirement for an on-street bike facility along Arapahoe would have
specific benefits in locations outside of the Twenty Ninth Street site. As examples, by
not having 5 foot bike lanes on both sides of Arapahoe, a 10 foot narrower street width
for pedestrian crossings at all intersections along Arapahoe can be achieved and there
would be less impact to wetlands and prairie dog habitat in the vicinity of Arapahoe and
Foothills intersection.
Disadvantages:The disadvantage to eliminating the on-street bike facility on Arapahoe is
that this would eliminate a dedicated bike-only facility, thereby requiring bikers to use
the multi-use path along either side of Arapahoe or mix with vehicular traffic as they do
today.
Staff recommendation: Because there are planned and/or existing multi-use paths on both
sides of Arapahoe and also a parallel multi-use path facility nearby in the Boulder Creek
Path, staff believes that the additional road width and its negative impacts outweigh the
benefits of adding an on-street bike facility that may not be completed for many years.
Thereforestaff recommends that the Arapahoe on-street bicycle facility be removed from
the BVRC Connections Plan.
th
C) Replacement of multi-use path along 29 Street with sidewalk and on-street bike lane
th
The BVRC Transportation Connections Plan shows a multi-use path along 29 Street
th
from the Boulder Creek Path, north through the 29 Street development area and Target
and then continuing north beyond Pearl Street. The multi-use path currently exists south
of Arapahoe and is under construction by Target along the front of the store. The Twenty
Ninth Street development plans show 8 foot wide detached sidewalks along both sides of
th
29 Street with on-street bike lanes consistent with city standards. These on-street bike
lanes would occur along the back of head-in parking spaces.
Advantages:The most important advantage of this proposed amendment is that this
alternative design would separate bicycles and pedestrians in the vicinity of the plaza area
central to the development where pedestrian activity is expected to be most intense.
Another advantage is that bikers will be able to move more freely along a dedicated
facility than one where they must compete with pedestrians and shoppers. A third
th
advantage is that with head-in parking along the sides of 29 Street, bikers would not be
expected to freely move between the street and the multi-use path, and the path might not
be effectively used by bikers even if designed to accommodate them.
Disadvantages:The disadvantage to this alternate design is that there would be that a
transition from paths on the north and south ends of the on-street bike lanes may be
th
awkward especially in the location of Walnut and 29 Street. Details of this transition
area will need special consideration when staff reviews the more detailed final plans at
Technical Document review.
Staff recommendation: Staff has reviewed the design alternatives and also met with
Boulder Bicycle Commuters (BBC) to discuss the plan. Staff and most members of the
AGENDA ITEM #________PAGE________
BBC agree that a multi-use path along a busy pedestrian area is not a good design. There
th
were mixed feelings about having a bike lane due to the additional width of 29 Street
th
and higher potential vehicular speeds along 29 Street. However, a designated bike lane
would provide additional space for bicyclists in the area where head-in parking is used
within the plaza area. Based on staff’s assessment of the issue and input from the BBC,
th
staff recommends that the multi-use path shown along 29 Street between Arapahoe and
Walnut on the BVRC Connections Plan be replaced with sidewalk and on-street bike
lanes.
th
D) Removal of a portion of north-south Secondary Vehicular Connections between 29
th
and 30 Streets south of Canyon
The BVRC Connections Plan shows this connection extending through the site from
Arapahoe north to Canyon and beyond. The Twenty Ninth Street development plan
shows removal of a portion of this planned connection where it would conflict with a
proposed large retail building. This connection would still exist as a landscaped sidewalk
connection from Arapahoe to the front of the building and would include an access for
bikes, pedestrians and vehicles to and from Arapahoe.
Advantages:The advantage of removing this portion of this connection is that a building
and parking lot configuration can be accommodated on this portion of the site. This
configuration would include a well landscaped pedestrian corridor connecting Arapahoe
to the front door of the retail building at this location.
Disadvantages:One disadvantage of removing this portion of the connection is that the
th
internal circulation for the site depends more on 29 Street for north-south circulation.
Another disadvantage of removing this connection would be that pedestrians wishing to
move north through the site in this alignment would need to walk an additional 250 feet
th
west to 29 Street to continue to their destinations. It is not expected that this pedestrian
route will be a high demand one for pedestrians moving through the site, so this
disadvantage may not be significant for most users.
Staff recommendation: Staff considered this connection in terms of the overall plan and
feasibility of a large anchor retailer in this location. The value of a direct pedestrian link
from Arapahoe transit to the front door of the anchor store is believed to be a significant
benefit to the site, particularly for employees working at this location. Therefore, staff
recommends the proposed removal of a portion of this Secondary Vehicular Connection
thth
between 29 and 30 Streets.
th
E) Removal of a portion of north-south Secondary Vehicular Connections between 28
th
and 29 Streets south of Canyon
By eliminating a portion of this connection, a vehicular/bike/pedestrian access point to
Arapahoe shown on the BVRC TCP would not be constructed. Internal circulation would
still be available within parking aisles. The BVRC Connections Plan shows this
connection to Arapahoe at a right-in/right-out access for vehicles. The connection as
shown on the Twenty Ninth Street plan achieves internal circulation but does not
intersect Arapahoe as envisioned by the BVRC Connections Plan.
AGENDA ITEM #________PAGE________
Advantages:This proposal would allow for a large retail building with a well landscaped
parking lot. Alternatives with this connection to Arapahoe would require more pavement
dedicated to parking. Also, an additional connection to Arapahoe in this location would
create impacts from the regulatory 100-year flood plain that would severely limit the
development potential of the southwest portion of the site.
Disadvantages:Without direct connectivity to Arapahoe along this alignment, some
th
additional traffic be routed to the 29 and Arapahoe intersection. This additional traffic
would cause more delay for vehicles at this intersection but would not cause significant
congestion. Access to and from Arapahoe for bikes and pedestrians would be available
th
approximately 250 feet south of this alignment at the corner of 28 and Arapahoe. This
corner of the site will feature wide sidewalks, a future transit superstop, signage and
significant landscaping.
Staff recommendation: Due to the limited benefit of extending the alignment of this
secondary connection through to Arapahoe for vehicular traffic and the relatively short
additional walking distance for pedestrians, staff supports amending the BVRC
Connections Plan to be consistent with the Twenty Ninth Street plan.
F) Alterations to alignments of Multi-Use Paths internal to the site and changes of several
multi-use paths to pedestrian sidewalk connections
The BVRC Transportation Connections Plan identifies multi-use paths on portion of the
th
29 Street development parcel south of Canyon as “conceptual alignments”. The
alignments of connections south of Canyon are proposed on the Twenty Ninth Street
development site review plans. These proposed alignments connect the exterior of the
th
site to uses within the interior of the site and 29 Street and Canyon. The connections
both south and north of Canyon have been designed as 5 foot sidewalks with significant
landscape buffers. The BVRC Transportation Connections Plan defines multi-use paths
as 10 feet wide, therefore the 5 foot width would be an amendment changing multi-use
paths to Pedestrian Connections. The proposed pedestrian connections are more
numerous and provide improved connections throughout the site than the number of
multi-use path connections envisioned in the BVRC Transportation Connections Plan..
Advantages: The sidewalks’ narrower widths allow them to be better incorporated into
parking lots and allows a more fine-grain of connections than could otherwise be
achieved with wider multi-use paths. The landscaping associated with the sidewalks
helps not only to buffer the sidewalks from parked vehicles but also provides a shaded
and more pleasant pedestrian experience and increases the feasibility of the site as a
pedestrian and transit accessible development. This pedestrian environment would best
serve pedestrians and transit riders as they walk from the exterior to the interior of the site
and also provide better quality connections between buildings. This is likely to reduce
short vehicle trips within the site.
Disadvantages:The disadvantage to this proposal is that the connections themselves
would not effectively serve bikers along those alignments. The BVRC Connections Plan
AGENDA ITEM #________PAGE________
envisioned multi-use paths at one-block spacing. This proposal would create bike
connections at approximately two-block spacing in the east-west direction, which means
that bikers would need to travel an extra 250 to 300 feet to reach an east-west bike lane or
multi-use path.
Staff recommendation: Staff assessed this issue by evaluating the costs and benefits of a
well landscaped and closely spaced pedestrian environment versus the improved bicycle
accessibility achieved with multi-use path facilities. The landscaped sidewalks proposed
achieve a goal of a closely-spaced network for the pedestrians who would benefit the
most from this configuration. Bicyclists would have facilities around the perimeter of the
th
site as well as along Canyon, Walnut and 29 Streets. The bike facilities would be
spaced at two-blocks apart in the east-west direction with the option to use parking lot
aisles between those two-block spacings. In most areas pedestrians would have facilities
spaced at one-block separations in both the north-south and east-west directions. If a
multi-use path network were to be implemented at one-block spacing in the east-west
direction as envisioned with the BVRC Transportation Connections Plan, the quality of
these connections and the site plan would be reduced due to the decrease in landscaping
or a decrease in the developable density of the site due to parking impacts. Due to the
higher quality and increased connectivity proposed, staff recommends the proposed
alterations to the alignments of Multi-Use Paths internal to the site and the proposed
changes of several multi-use paths to pedestrian sidewalk connections.
Other Board and Commission feedback:
At the time of the TAB hearing on June 14, 2004, BURA and Planning Board have not
th
yet reviewed the BVRC Connections Plan amendment requests or the 29 Street site
review proposal. Concept review comments from both Planning Board emphasized
th
additional landscaping, particularly along the 29 and Canyon corridors and achieving
good connections throughout the site. All three reviewing boards requested that
reasonable flexibility be used in the design and review of the BVRC TRC and that a
rigid, uncompromising application of this plan be avoided.
Public feedback:
As part of the January 14 agenda item, an opportunity for public comment will be
provided. Additionally, the following comments were received by staff:
After the initial submittal, staff presented the plan to the Boulder Bicycle
Commuters at their March 1, 2004 meeting. A summary of comments collected
at that meeting has been included as an attachment to this memo.
An individual comment from a member of the Boulder Bicycle Commuters group
th
requesting that the proposed 29 Street bike lane not be constructed and instead
create a narrower street width to help slow traffic. This e-mailed comment is
included as an attachment to this memo.
A statement from Walk Boulder, a pedestrian advocacy group, is also included as
an attachment. This statement includes requests for adequately wide multi-use
paths and wider and more frequent sidewalk connections than are shown on the
site plan. This e-mailed statement is included as an attachment to this memo.

Boulder Bicycle Commuters Meeting, March 1, 2004
Summary of the Twenty Ninth Street redevelopment discussion
As a general note, the meeting was informative and the group was well educated
regarding the issues and also the history behind the BVRC plan. Many of the members
understood the challenges of trying to create a large retail center that would be
welcoming to bicyclists. Some specific issues that were highlighted included:
-Center line striping of the multi-use paths similar to that used along the Boulder
Creek Path should be considered if appropriate.
-Consideration of whether bikes would be allowed on the internal sidewalks
-Concern about how enforcement would occur if the internal streets, sidewalks,
and paths are privately owned and maintained
th
-A 29 Street center bike lane would have difficulty in transitioning from the M.U.
path to the center lane at both ends.
-There should be diagonal connectivity from the corners of major intersections,
even if the diagonal connection only leads to parking lot drive aisles
-Where M.U. paths and sidewalks cross parking lots, parking spaces need to be
removed where the paths and sidewalks cross drive aisles
th
-Crossings of 30 Street need to connect to paths and sidewalks internal to the
Crossroads site
-Covered bike parking including bike trailer accommodations need to be
distributed around the site. These need to be well connected to bike routes. The
Sunrise Center’s parking lot path was called out as being poorly designed and
inadequate.
-Crossroads would be an excellent location for a bike station for tune-ups.
-The internal paths not only need landscaping buffers but need to be wider to
accommodate bikes
th
-The connection from the corner of 28 and Arapahoe should accommodate bikes.
If it cannot continue through the parking lot, this area should have good covered
bike parking.
-Generally, Westcor’s plan is an auto-centered plan and needs to better account for
bikes.
th
-There is no significant auto-free zone along 29 Street.
-Retail along the exterior of the site needs to face the streets, not the parking lots.

WALK BOULDER
Statement on the redevelopment plans for
Crossroads Mall
As Boulder’s voice for pedestrians, Walk Boulder is primarily concerned that the
redevelopment of Crossroads Mall will provide adequate facilities to ensure the
safety and comfort of pedestrians.
Accordingly, we offer the following observations and suggestions about the plans
that have been submitted for the mall’s redevelopment:
From the point of view of the pedestrian, the redevelopment of Crossroads
th
Mall, proposed to be renamed 29 Street, should not be oriented inward
but should instead be integrated into the fabric of Boulder. That means
th
having attractive streetscapes along its outer boundaries, including 28
th
Street, 30 Street and Arapahoe Avenue. Such design features should
th
offer convenient pedestrian access to the tenants and facilities of 29
Street.
th
We are particularly concerned that the current plans for 29 Street call for
an uninviting large parking lot in front of the “big box” retailer at Arapahoe
th
Avenue and 30 Street, a curb/sidewalk cut in Arapahoe Avenue between
thth
29 and 30 streets for that retailer, blank walls with no pedestrian access
th
to the cinemas along 30 Street and a blank wall along Arapahoe Avenue
th
at 28 Street for the smaller anchor tenant, likely to be a supermarket.
In addition, the plans for the “big box” retailer turn the back of the building
to the Canyon Boulevard extension, offering pedestrians a view of truck
loading docks and blank walls. From a design perspective, it is important
for pedestrians to have a sense of “transparency” (provided by windows,
doorways, passageways, etc.) when walking next to buildings.
In short, we believe that the developer’s plan shows particularly poor
th
attention to how the 29 Street project will relate to Arapahoe Avenue and
th
30 Street, both major Boulder thoroughfares and pedestrian corridors.
The City of Boulder should require the developer to provide more, wider
and better-placed sidewalks within surface parking areas so that
pedestrian interaction with automobiles is limited. Also, any driveways
leading into the project from the adjacent boundary streets should have
sidewalks on both sides.
th
In a project as large as 29 Street it is important that sidewalks and public
spaces be designed as welcoming places. That means sidewalks should
be at least ten feet wide (so two couples can pass comfortably), have
AGENDA ITEM #________PAGE________
planting buffers (with shade trees) between the sidewalks and the curb
and provide amenities along the sidewalks such as benches, drinking
fountains and information kiosks.
Every effort should also be made to separate pedestrian facilities from
bicycle traffic and other wheeled traffic, such as scooters and electric
bikes. Ideally, bicycle lanes should be provided on all streets within the
project as well as bicycle racks and signs indicating dismount zones.
If a sidewalk is designated as a multi-use path, federal guidelines should
be followed (recommended width of twelve feet with a minimum of ten
feet). If there is no physical separation of pedestrians and bicycles on a
mutli-use path lines should be painted to indicate proper use. For the
safety of pedestrians, no motorized vehicles (such as electric bicycles or
th
Segways) should be permitted on sidewalks or multi-use paths within 29
Street.
In addition to the items listed above, Walk Boulder also agrees with the issues
raised by David Beik, Richard Epstein and others regarding the overall
development concept for the Crossroads redevelopment. In particular, we believe
that the following issues should be thoroughly addressed before final approvals
are given for the redevelopment of Crossroads Mall:
th
In the current plan 29 Street has no central public space, such as a park
or plaza. From the pedestrian point of view, this should be an essential
th
part of the development in order to provide 29 Street with spaces for
enjoyable human interactions and to foster a sense of community. For the
person on foot a central park or plaza would give character and identity to
the project. It would also provide a destination, a meeting spot and a place
to relax. Additional public facilities, such as water features or public art,
could be incorporated in the central park or plaza.
th
Nothing in the plan suggests that 29 Street is located in Boulder. As
th
currently proposed, 29 Street is simply a shopping center with a design
that could just as easily be located in Phoenix, Charlotte or Indianapolis as
in Boulder. Some distinctive signature Boulder features should be included
in the plan, similar, for example, to the stunning rock and water features
on the Pearl Street Mall.
Crossroads should be redeveloped as a mixed-use project, incorporating
retail, residential and office uses. Development of a single-story complex
is more appropriate to a suburban site than an urban setting such as
central Boulder. At the very least the developer should be required to
th
include multi-story buildings along 29 Street in the center of the project
between Canyon Boulevard and Walnut Street, with upper floors providing
office and residential uses. In conjunction with a central plaza, these
AGENDA ITEM #________PAGE________
buildings, probably two to four stories in height, would help create a more
urban environment comparable to Pearl Street, which is a national model
for pedestrian-friendly development.
Walk Boulder appreciates the opportunity to offer these observations and
suggestions to the City of Boulder staff, Transportation Advisory Board, Planning
Board and City Council.

Public Comment Received Related to BVRC Transportation Connections Plan
Received March 3, 2004 via e-mail:
Steve, thanks for visiting Boulder Bicycle Commuters on Monday to get
our input on the proposed Crossroads redevelopment. My biggest
remaining concern for bikes in the plan is the consideration of putting
bike lanes next to diagonal parking, specifically on 29th St. This
sounds like a bad idea. I don't believe it's safe to ride on the right
side of the lane next to diagonal parking, because a bike is much less
visible there to cars backing out. Most experienced cyclists know this
and would ignore bike lanes. Inexperienced cyclists might not know
this, and shouldn't be encouraged to ride on the right where they are
in jeopardy.
Instead, I think the best solution is to engineer the street for very
slow traffic speed, so bikes feel safe using the general purpose lane.
The street already has some curves, which is a good start towards
breaking up the line of sight and keeping auto speeds down. The next
step would be to make the street cross-section as narrow as possible.
I would prefer to see the street narrower than west Walnut St. between
9th and 11th, which similarly has diagonal parking on both sides.
Marked pedestrian crossings, center bollards, etc. would also help to
make sure the street feels very slow to cars.
For added encouragement, it would also be desirable to post "Cyclists
use full lane" signs as are currently used around Boulder on some
downhill lanes.
It's always difficult to engineer a single feature to accommodate all
types of cyclists: fast, slow, experienced, inexperienced. But in this
case I think bike lanes would be a disservice to all of them.
Thanks.
