ITEM NO. ~~
BACKGROUND:
In November 1999, the City Council directed staff to prepare three Specific Plans for various portions of
the downtown area of Dublin to guide the development and revitalization of the West Dublin BART,
Downtown Core and Village Parkway areas. The Specific Plans were adopted by the City Council on
December 19, 2000.
As a part of the implementation of the Specific Plans, streetscape improvements are necessary in the West
Dublin BART, Downtown Core and Village Parkway Specific Plan areas to provide continuity and
unifying elements to establish a positive image in the downtown area. Each Specific Plan contains
guidelines and concepts for the design of the streetscape improvements addressed within the Plan. Prior
to construction of these improvements, the basic designs for the streetscapes, plazas, gateways, and street
furnishings associated with the downtown planning area must be determined, cost estimates obtained, and
a phasing plan developed. During the public hearing process on the Specific Plans on November 21, 2000,
the City Council approved a contract agreement with the consulting firm, Freedman Tung and Bottomley,
to prepare the Downtown Streetscape Implementation Program.
Staff has been working with the Consultant over the last few months to develop some preliminary
concepts for various physical streetscape improvements for the downtown. The consultant has developed
some elements for entry features and gateways in three areas, and a hierarchy of streetscape monuments,
signage, bus shekers, benches, street furnishings and lighting, as well as a plaza design for the Downtown
Core Specific Plan area. Possible locations for these' features have also been identified by the consultant
in the Plan graphics.
The consultant' s plan follows the recommendations related to physical streetscape improvements in the
Specific Plans. The actual capital improvements to be completed in the three Plan areas and
implementation phasing will be determined after direction is given by the City Council on the options
presented tonight for streetscape improvements. In conjunction with the design portion of the program,
priorities for construction will be developed further, and specific cost and funding will be determined for
each of the improvements. The tasks undertaken by the consultant will provide a document to guide the
preparation of construction documents. Once the City Council has identified the preferred options, staff
will return at a later date with more detailed cost and design information.
Tonight the staff and David Evans of Freedman Tung and Bottomley will present specific options for
various elements of the Downtown Streetscape Plan. Mr. Evans will start with a discussion of the overall
opportunities for improvements in the Downtown Area (Attachment 1 ).
Gateways
Gateways are the locations that delineate major entryways to downtown, as well as locations along major
streets that define entryways to significant land uses, transportation elements (i.e. West Dublin BART
Station) or freeway access points. As primary locations for identification elements, these gateways serve
to inform the driver and pedestrian that they have arrived at a significant place. Priority gateway
entrances to Downtown are:
Primary
Dublin Boulevard at Village Parkway near the 1-680 overpass
· Dublin Boulevard at San Ramon Road
· St. Patrick Way at Amador Plaza Road near the new off-ramp from 1-680
Secondary
· Amador Valley Boulevard at the 1-680 overpass near Village Parkway
· Amador Valley Boulevard at San Ramon Road (Casa Orozco)
Other locations for entryways are also shown on Attachment 2. These locations, although important
entryways, are not major entrances to the downtown.
In Attachment 3, optional gateway monuments, signage and a custom designed gateway feature are
presented. These options are as follows:
Option 1 - Brick Monument: Brick clad monument structure with white open metalwork light
tower. Approximately 25' in height for primary gateways, with a 6'x 6' base measurement, can be
scaled down to a smaller/shorter monument for secondary gateways.
Pros: Brick could match other downtown buildings such as the Enea buildings, the Fire
Station and the existing library.
Cons: Matching brick may be difficult and look too "busy" at certain locations.
Option 2 - Masonry Monument: Masonry clad monument with white banding to match metalwork
on light tower, approximately 25' in height for primary gateways, with a 6'x 6' base measurement,
can be scaled down to smaller/shorter monument for secondary gateways.
Pros: The light colored masonry applied to the structure is more simple and modem
looking when compared to the brickwork in Option 1. It also reflects the masonry style of
the existing Civic Center building and new Dublin library (proposed) providing a unifying
element between the Civic Plaza area and the downtown.
Cons: The smaller brick element of Option 1 might provide a more unifying and historic
nature that blends well with some recent buildings in the downtown area.
Option 3 - Signage: Optional items that can be used in conjunction with the gateway monuments
described in Options 1 and 2 are half-cylindrical marquee-style signs or directional signage.
Located at strategic high traffic volume intersections, the gateway monuments can potentially
incorporate marquee-style signs to establish a location or directional signage to assist both drivers
and pedestrian in finding specific locations in the downtown area. For instance, a monument at
the comer of Golden Gate Drive and Dublin Boulevard could contain signage to direct people to
the West Dublin BART Station or the proposed hotel adjacent to the station. A monument at the
intersection of Village Parkway and Dublin Boulevard may incorporate a marquee-style sign to
announce that the visitor has reached Village Parkway, and also include directional signage for the
services on Village Parkway and those in the Downtown Core area. The monument structure at St.
Patrick Way and Amador Plaza Road may provide an opportunity to include signage directing
travelers to Dublin Boulevard, the BART station, and to new large-scale office developments.
Pros: Signage would assist both pedestrians and motorists in locating services and
facilities.
Cons: Too many signs on a monument might create confusion or be distracting to
motorists.
Option 4 - Custom Designed Gateway Feature: This option is a variation of the gateway
monument options, with a bridge-style framework. Omamental light colored metal work is used as
a cross-street decorative arch attached to monument columns spanning St. Patrick Way at Amador
Plaza Road and the 1-680 off-ramp. A gateway feature such as this was also considered for
location on Dublin Boulevard near the intersection of Amador Plaza Road. However, the City
Council will be considering the possibility of adding artwork and other fagade improvements to
the 1-680 overpass near this location, and a bridge-style gateway feature could interfere with the
visual enhancements. Additionally, although also a major entrance to the downtown area, the
width of the roadway at the intersection of Dublin Boulevard and San Ramon Road would
preclude the potential for such a feature at that location. Therefore, it was determined that
installing the gateway feature at another entryway (St. Patrick Way and Amador Plaza Road) to
the downtown area would be more suitable and cost effective. The estimated cost for this gateway
feature is $287,000 (includes landscaping, demolition and trenching). Since the City does not own
enough right-of-way at this intersection for the structure and enhancements, an approximately 200
square foot area needs to be acquired from the property owner. The cost of the acquisition is
estimated at $16,000. With a 20% contingency added, the project total is estimated at $364,200.
Pros: Provides main entrance to the downtown area near the intersection of the two
interstate freeways. Directional signage, as described under Option 3, to the new BART
Station can be included on the monument feature. Would be easily seen from the freeways
which are elevated above the area.
Cons: Cost is more than twice that of the basic monument feature, as two monuments and
the metal arch are included in the structure.
Suitable for major gateways, either of the first two options could be located at one or more comers of
major entryways to the downtown. Smaller height versions, with one gateway monument and associated
signage can be built at the secondary locations. Priorities for near-term construction could be:
4
· St. Patrick Way at Amador Plaza Road (Primary)
· Dublin Boulevard at San Ramon Road (Primary)
· Village Parkway at Dublin Boulevard (Primary)
At the northwest comer of Village Parkway and Dublin Boulevard, there exists the opportunity to install a
gateway monument within the City-owned right-of-way. The cost of the monument alone is estimated at
$115,000. The addition of a marquee-style sign, directional signage, landscaping enhancement,
demolition and trenching, and a 20% contingency, the cost is estimated at $159,000.
Although the secondary gateway at Amador Valley Boulevard and San Ramon Road is not within the
boundaries of one of the recently adopted Specific Plan areas, it is included in the area covered by the
Downtown Specific Plan adopted in 1987. It is also a logical point of entry, or gateway, into Dublin's
Downtown. Additionally, the business at the noaheast comer of that intersection, the Casa Orozco
restaurant, recently expanded and has been working with staff to improve the adjacent parking area,
giving rise to an opportunity to provide an entry feature and new landscaping at that comer. On April 17,
2001, the City Council approved the modification of the easement at that comer to set aside a sufficient
amount of area for a future entry feature. The entry feature could be a gateway monument design as
shown on Attachment 3, or a variation of the design, with enhanced landscaping, and could also be
reflected at the other three comers of the intersection. The existing signage at the comer in front of the
restaurant, logos for various service groups in Dublin, could be incorporated into the monument, if
desired.
Streetscape Plans
Along the major streets (Dublin Boulevard, Village Parkway, San Ramon Road eastern side and Amador
Valley Boulevard) a streetscape plan is proposed. This phase of the consultant' s work focuses on
streetscape plans for Dublin Boulevard and Village Parkway because they represent two high priorities for
improvements in the Specific Plans. Once a specific design for major streets is complete, it can be
translated to other streets identified on Attachment 2 (Golden Gate Avenue, Regional Street, Amador
Plaza Road, and St. Patrick Way).
The proposed streetscape plan includes several elements such as wider sidewalks, an increase in the
number of street trees located adjacent to lhe streets, and new decorative streetlights located along the
street to impart character to the street environment. Associated street furniture, benches, trash enclosures
and a bus shelter option (Attachment 4) have been proposed. It is important to mention that the City
Council has already instructed staff to create three special bus shelters along Dublin Boulevard that would
be designed by artists. The shelters proposed within the scope of this project could be used elsewhere in
Downtown to complement other elements of the streetscape and could accommodate poster art or other
such elements as advertising, as well.
Street Lighting (Attachment 4)
Two different "boulevard-style" streetlights are suggested in Attachment 4. Each has a pair of lights near
the top of the pole which is proportionate to the scale of the street. Lower light fixtures are located below
the main light fixtures on the pole to provide pedestrian-scale lighting. Large banner or metal cutouts can
be used on either style fixture to advertise events or other information. The light fixtures would be
located next to the sidewalk adjacent to the roadway and the cobra-head lights in the center median would
remain.
Both of the proposed styles would have "anti-graffiti" coating to prevent tagging, and a variety of color
coatings could be used. Attachment 4 shows the poles painted white, similar to those used along "Auto
Row" on Broadway in Oakland. These poles have not been subjected to "tagging." However, because of
the light color, more frequent maintenance and cleaning may be necessary if the poles are painted white.
Option 1: Transit Series (Lumec) Design - These streetlights are designed typically for areas when
transit facilities are located (i.e., near BART Stations or bus shelters).
Pros: A functional style light fixture that is reminiscent of those used in waterfront areas or
corridors where there is a transit hub.
Cons: Plain, simple style may not provide interest to pedestrians and variety to streetscape.
Option 2: Custom Designed Luminaire (Lumec) - A custom designed streetlight typical 0fthe
type used on main streets and in downtown areas.
Pros: Style is reflective of a traditional downtown boulevard lighting fixture yet with
modern lines. The upper lantern is similar in style to the tower and lighting feature of
Gateway Monument Option 2.
Cons: This streetlight fixture is slightly more ornate and detailed when compared to the
transit series design. It may require slightly more maintenance time because of this.
In unique situations, such as under the overpass of the 1-680 freeway on Dublin, a specially designed light
fixture may be needed to illuminate the walkway area and compliment the proposed artwork. The fixture
could be designed to incorporate some of the elements of the streetlight design to provide continuity, but
would be either attached to the interior concrete wall or the ceiling.
According to the Public Works Department, after the initial capital cost of the 92 additional streetlights
proposed for Dublin Boulevard, the operating and maintenance cost of the new lighting per year is
estimated at $35,200. Since 44 additional streetlights are proposed for Village Parkway, the operating and
maintenance cost of the new lighting on that street per year is estimated at $16,835. Amador Valley
Boulevard would require approximately 76 streetlights for the streetscape improvements, and the
operational and maintenance cost per year is estimated at $29,070. Amador.Plaza Road would require
approximately 46 streetlights for the streetscape improvements, and the operational and maintenance cost
per year is estimated at $17,595.
Benches (Attachment 4)
Street benches would be added to the streetscape under the Implementation Plan as recommended in the
Specific Plan. The benches would be installed in the downtown area and on Village Parkway to provide
6
seating for pedestrians. Typically, the benches would be placed in the rear portion of the sidewalk near
storefronts or on concrete pads adjacent to the sidewalk at street intersections. Three different bench
designs are provided. in Attachment 4:
Option 1: Hess America, Corvus Bench - A basic bench style with straight back and fiat seat.
Pros: Simple design fits any streetscape theme. Easy to maintain either to clean or paint.
Associate cost may be less than other designs.
Cons: Design provides little interest or style to streetscape.
Option 2: Landscape forms, Presidio Collection - Backless bench with wave style seat.
Pros: Width is wide due to backless style of seat. Provides seating surfaces on both sides.
Cons: Without back, seat may be uncomfortable, particularly for the elderly. Untraditional
design works better in park areas than in urban streetscape.
Option 3: Landscape Forms, Presidio Collection - Stylized, contoured metal bench with curved
back.
Pros: More traditional streetscape bench design, with curved back and contoured seat,
provides more comfortable sitting area. Easily fits in with other elements added to
streetscape (lighting, landscaping etc.).
Cons: Cost may be higher than 'Option 1 because of the stylized design. Due to the curved
surface, maintenance may be slightly more time consuming depending on the color chosen
for the bench.
Bus Shelter Concept (Attachment 4)
The City Council has several options for bus shelter design in the downtown area. The consultant has
developed one design concept that is reflective of Option 2 of the gateway monument designs which could
be used throughout the area. This design concept is shown in Attachment 4. Another bus shelter option is
to have all shelters specially designed for each particular location. The City Council has directed staff to
investigate artist designed bus shelters for three locations on Dublin Boulevard. These will be presented
to the Council at a later date. Additionally, the Council may determine that the present policy of LAVTA
("Wheels") of supplying and maintaining the basic metal bus shelters is more cost effective and
preferable. These various options are discussed below.
Option 1 - Uniform Design: The bus shelter design incorporates a light colored pre-clad masonry
material on exterior columns, similar to Option 2 of the gateway monument designs, with white
metal work reflective of the monument tower feature. Open side windows allow panels to be
inserted at the ends, which may contain artwork or posters for events. An alternative to this would
be to completely enclose the sides so no side window is included in the design for art or posters.
7
These could be used throughout the downtown area except where specially designed shelters are to
be located.
Pros: A more substantial structure than most bus shelters, the option would offer better
protection to bus riders in inclement weather. The design would compliment streetlight
and gateway monument design, providing a unifying element to the streetscape.
Cons: This bus shelter design would be more expensive to purchase and maintain than a
standard metal shelter as the City would be responsible for it,'but less expensive than a
shelter specially designed by an artist.
Option 2 - Artist Designed: The Council has directed Parks and Community Services staff to
contract for designs for three artist designed bus shelters to be used on Dublin Boulevard to
replace existing shelters. Additional shelters could be specially designed for other locations in the
downtown area to enhance a particular location.
Pros: Each bus shelter would be of a unique design and might incorporate elements of the
surrounding streetscape, particular historical period or event, or theme. The shelter could
serve as public art in the streetscape of the downtown.
Cons: The initial cost of each bus shelter would be greater than that of the other two
options since it would an artist designed structure. Additionally, maintenance costs could
be greater if various textures, materials and colors are incorporated into the design.
Option 3 - Standard Metal: This is the standard metal bus shelter used throughout the area served
by LAVTA. It features black metal poles and benches, with acrylic side, back and roof panels.
Pros: The bus shelter is provided by and maintained by LAVTA at no cost to the City.
Cons: The design is very basic and boxy, and does not add an artistic or quality element to
the overall streetscape. If other elements are added to the streetscape or changed, the
existing bus shelters may be inconsistent with the design and materials of other
improvements.
Street Trees Concept
As discussed in the Downtown Specific Plans, the location of trees along the front of the sidewalk nearest
the roadway creates a boulevard style streetscape. It also provides a visual barrier between the pedestrian
and motor vehicles/motorist. The Specific Plans contain a preferred plant matrix listing the trees, shrubs
and ground covers to be installed in the downtown area. Possible street trees for the streetscape as
proposed by the Specific Plans are: Raywood Ash, Chinese Pistache, and Chinese Hackberry.
Under the guidelines in the Specific Plans, street trees are recommended to be located approximately 30
feet apart along the streetscape. The existing trees on Dublin Boulevard are spaced at intervals of 40 feet,
and those on Village Parkway are spaced 30 to 35 feet apart.
8
Village Parkway Specific Streetscape Design (Attachment 6 & 7)
Special attention has been given to determine some possible streetscape improvements for this area.
Existing conditions include a six-foot sidewalk with tree located at the back of the sidewalk area
approximately five feet from face of curb. Ornamental pear trees are planted along Village Parkway at 30
to 35 foot intervals. The street pedestrian crossings at Amador Valley Boulevard, Lewis Avenue and
Dublin Boulevard are long, and no pedestrian amenities exist along the sidewalk. Attachment 7 illustrates
two concepts for Village Parkway improvements and design elements which are discussed below. A third
concept, a modification of the other two, is also discussed below.
Concept A: Trees and sidewalks to be maintained as exist with trees located five feet from face of
curb and six foot sidewalk. Enhanced median landscaping, pedestrian nubs or bulb-outs, with
benches and small plazas added at the bulb-out locations. The consultant' s cost estimate in
Attachment 9 for this concept includes all of the streetlights along Village Parkway and is
$1,765,440. For the first phase of the streetscape improvement program, the staff recommendation
is to install only the improvements and streetlights at Village Parkway and Lewis Avenue
($510,320) and the gateway monument at Village Parkway and Dublin Boulevard ($159,000) for
an estimated cost of $669,360 for both projects.
Pros: Upfront cost is less because existing trees and walkway remain, less disruption for
businesses; allows some initial investment and time to measure return before more
expenditures.
Cons: If at a later date, the City wants to go ahead with expanding sidewalks and
moving/replacing trees and installing streetlights along the entire stretch of Village
Parkway, as shown in Specific Plan, cost at that time may be higher. The use of the
existing sidewalk without expansion doesn't create the boulevard-style streetscape
envisioned in Plan. Small concrete pads to the rear of the sidewalk would be needed for
street furniture such as benches and trash receptacles.
Concept B: Sidewalks would be widened to 10 feet, and existing trees removed and new street
trees planted. Streetlights, pedestrian nubs or bulb-out, two plazas, enhanced median landscaping
and benches added with a gateway monument at two intersections. This option is estimated to cost
$2,688,360 at completion (see Attachment 9), including right-of-way acquisition.
Pros: Would conform to streetscape improvements shown in Specific Plan and provide
boulevard-style streetscape.
Cons: Would be more disruptive to businesses and cost would be greater. Could require
additional purchase by City of two feet of fight-of-way for sidewalk expansion (eight foot
right-of-way currently exists).
Concept C: This option is a modification of Concept A and B with phased improvements.
Sidewalks would be widened to eight feet within the existing fight-of-way as planned under the
current CIP. Additional streetlights and street furniture would be installed, and bulb-out would be
installed at all intersections. As the existing trees are located at intervals in general conformance
with the adopted Specific Plan (30 to 35 feet apart), the trees would remain as long as they survive
the sidewalk widening.
Pros: Would allow completion of the sidewalk widening improvements as planned in the
CIP, and also include additional improvements such as streetlights and benches called for
in the Specific Plan. It would also create a more pedestrian-oriented environment with the
wider sidewalk and street furnishings. With the existing trees remaining at their present
location, less disruption of the sidewalk would occur during the construction phase and the
appearance of the streetscape would not be altered as much as with all the trees removed
and new trees planted closer to the curb.
Cons: It is possible that with the widening 0fthe sidewalk and the undercutting of the
roots, the trees may die. If this occurs, replacement will be necessary. The City could
either replace the trees at the same location or develop a phased replacement program to
move the trees adjacent to the curb, as recommended in the Specific Plan.
Given the stable present development along this street, a specific project either at the intersection of
Amador Valley Boulevard/Village Parkway or LewisAvenue/Village Parkway could be accomplished in
the short-term and other improvements along Village Parkway completed as time and money permii.
Dublin Boulevard Specific Design (Attachment 5)
Dublin Boulevard is the primary central street in downtown. The roadway is six lanes with median from
San Ramon Road to Village Parkway. Cobra-head lights are located in the median and street trees are
spaced approximately 40 feet apart. The present streetscape is dwarfed by the road and pedestrian usage
is minimal due to the fact that most buildings are set back far from the street behind large parking areas.
Major development is contemplated for areas west of the Golden Gate Avenue area (Safeway, Dublin
Place, possible Crown Chevrolet site) and the design suggested here can be partially be implemented by
private interests as well as the City. A gateway monument project could be incorporated within the
landscaped area in conjunction with the upcoming Safeway project at Amador Plaza Road or west of the
Golden Gate intersection. An improved pedestrian atmosphere, including more street trees next to the
curb, decorative lighting and street furniture as proposed will go a long way in improving the streetscape.
No options have been proposed for this street but the design includes:
· Street trees approximately 30 feet on center (species as identified in the Specific Plan) wherever
possible, otherwise, at existing 40 foot intervals
· Decorative streetlighting at the curb
· Three artist-designed bus shelters at various locations and/or shelters as discussed in previous
sections of this report
· Intersection gateway monumentation at the following intersections with identification signage:
Amador Plaza Road, Golden Gate Drive, Regional Street and the main entryways at Village
Parkway and San Ramon Road
10
Plazas (Attachment 8)
The Downtown Specific Plans have identified potential plaza sites in conjunction with the Dublin Place
shopping center (north of Dublin Boulevard), near the new West Dublin BART Station, along Village
Parkway and at the future location of Regional Boulevard and an extended St. Patrick Way. Most of these
sites will be dependent on future development possibilities or as a direct result of streetscape
improvements that may occur on the various streets. A prototypical.design has been developed by the
consultant (Public Plaza at Amador Plaza Road, Attachment 8) which shows features or elements which
might be included in the design of a plaza on Areadot Plaza Road in the Dublin Place Shopping Center.
The prototypical design developed by the consultant is conceptual only and was prepared to illustrate
important features to include in the design of a plaza to make it function as an attractive gathering place
for pedestrians. It is also anticipated that this will generate a discussion by the Council of ideas and
preferred features. Typical plaza features, as shown in the consultant' s conceptual design, include a paved
plaza area with seatwell, trees, landscaping, irrigation and grassy areas located adjacent to walkways.
Prime locations for possible plazas in the near future include:
A Plaza at Amador Plaza Road and the driveway leading out of the Dublin Place shopping center.
This could be built in conjunction with proposed new Dublin Place Shopping Center
improvements now being contemplated. Features could directly relate to pedestrian seatwalls,
planters, benches and grassy areas for relief from the street and traffic at this location.
Plaza opportunities along Village Parkway in conjunction with streetscape improvements
(Attachment 6). These may be smaller plaza areas with minimal landscaping, seating, and special
paving or scored concrete.
If right-of-way must be acquired and the plaza is not developed in conjunction with a private project, the
estimated cost for a plaza such as that shown in Attachment 8 is $60,840 (see Attachment 9, item 6).
Establishing Priorities
Several factors will impact the timing of implementing Downtown Street Improvements. The highest
priority, given the timing of proposed new development downtown on the horizon, should be to initiate
improvements along Village Parkway and Dublin Boulevard, west of the Dublin Place Shopping Center.
Other areas of Dublin Boulevard, Amador Valley Boulevard and various secondary streets have major
projects (BART, Safeway, potential Crown Chevrolet Property, Dublin Place Shopping Center
improvements) pending which could soon be underway. Priorities should be established based on the
following considerations:
Timing of adjacent development - each street downtown is going to be impacted by new adjacent
development that may be proposed;the establishment of the new BART Station, etc. Special
attention should be given to timing improvements in conjunction with anticipated new projects.
11
· Particular development responsibilities for some or a portion of these improvements (particularly
sidewalks and plazas) need to be defined so that costs can be assigned.
· Final construction design of gateway, plaza and streetscape standards will take six months to
complete.
· This program will take many years to be completely implemented due to budget and capital
improvement considerations.
Financial Considerations of the Downtown Streetscape Implementation Plan
The Conceptual Cost Summary, Attachment 9 (following design concept plans in Attachments 1 through
8), outlines the estimated costs to complete the streetscape improvement implementation included in the
Specific Plans for various street segments. These are only preliminary estimates and a more specific
analysis of actual costs will be required as a part of the Capital Improvement Plan. Some of the costs
associated with specific improvements and designs have been discussed in previous sections of this report.
The cost estimates for the two concept plans for Village Parkway are contained in Items 1 and 2 of the
Conceptual Cost Stunmary, and include the estimated costs of the gateway monuments, plazas, pedestrian
nubs or bulb-outs, lighting, additional landscaping, street furnishings, and demolition and trenching.
Items 3 and 4 detail estimates for the gateway monuments, landscaping with irrigation, and demolition
and trenching to install the gateway features at the intersections of San Ramon Road at Dublin Boulevard
and St. Patrick Way at the 1-680 off-ramp. Item 5 pertains to the estimated costs associated with basic bus
shelters, streetlights, signage, additional street trees with irrigation, a plaza, pedestrian nubs or bulb-outs,
street fumishings, and demolition and trenching.
Additional costs which the City Council may need to consider at this stage in the implementation process
are those related to the operation and maintenance of the new streetlights. The lighting proposed with
streetscape improvements would be in addition to those already installed on Dublin Boulevard and
Village Parkway. These costs are discussed in the section on Streetlights.
Conclusion
Staff supports the premise of the Downtown Streetscape Implementation Plan. The City Council is being
asked to review the design concepts presented for the specific improvements. Staff recommends that the
City Council approve the following concept designs:
· Gateways - Option 2 (Masonry Clad)
· Streetlighting.- Boulevard light - Lumec custom design
Benches - Bench Option 3
· Bus Shelter - Uniform DeSign as presented for areas not specifically designated for Artist
designed shelters along Dublin Boulevard
· Street trees - Installed .along the curb at 30 feet on center where possible
· Plazas - First concept to be implemented at Amador Plaza Road in Dublin Place shopping center
· Village Parkway Streetscape Concept C - Widen existing sidewalks in accordance with CIP
· Dublin Boulevard Streetscape - As presented in Attachment 5
12
In addition, staff recommends that the City Council authorize three projects, including preparation of
more detailed cost estimates, to be considered in the 2001-2002 Capital Improvement Program.
· Final design and construction of the first gateway monument at the northwest corner of Dublin
Boulevard and Village Parkway.
· Final design and construction of the custom-designed gateway feature project at the intersection of
St. Patrick Way and Amador Plaza Road (I-680 off-ramp) as shown in Attachment 3.
· Final design and construction of a streetscape improvement at the intersection of Village Parkway
at Lewis Avenue as shown in Attachment 6.

SAN RAMCN BOULEVARD APPROACHING DUBLIN BOULEVARD
CUSTOM DESIGNED GATEWAY FEATURE
Gateway Concept
The dlverse "gateway' conditions of Dublln's Downtown
might otherwise appear to require completely different
]i
designs. However, Downtown Dub n is not chdrocterized
by strong historic architecture or consistent street 'room"
spaces formed by buiidlngs I~ke some other cities. These
gateway concepts represent o "system" approach that
creates a unlfylng civic image used flexTbly to
accommodate very different site conditions at proposed
entry IocaUons. The masonry cladding and white
metalwork is used as o storklng point, applied to the
towers but adjusted for their 'stand-alone" situations.
Towers would be clod with precost concrete or gloss fiber
reinforced concrete (GFRC). Alternatively, they could be
clad with tan brick to reinforce the brickwork of downtown
buildings such as the Enea Shopping Center Buildings, the
Fire Station, and public Library. Each tower would be
topped by an open ornamental metal "cupola~ with on
I effect at night
up]ight to create o welcoming antera
(shaft uplighting may also be provided). Ornamental
metalwork is used as a cross-street decorative arch
(~-680 off-romp at Saint Potrick's Way) or as a
cylindrical ornamental sign frame at "flanking* locations.

CUSTOM DESIGNED BUS SHELTER
Bus Shelter Concept
A shallow barrel-vaulted metal roof is
supported by a four-posted masonry
strdcture (probably plgmented precast
concrete). The front and sides of the
ctrdcture are open, whlie the rear is
covered By o thick perforated sheet
metal screen which provides some wind
and rain protection while allowing a
degree of visib~llty through, Horizontal
metal bands cross the metal screen
panels to link with the bonds of the
masonry posts, The open side
'windows" may be lnfilled with poster
panels (illuminated) if desired,
Masonry colors would match the
Gateway Monuments; the roof would be
white painted sheet metal (silver would
be an alternative); the perforated metal
screen panels ore o dor~ s3lver,
Boulevard-Scale Streetlight Concept
The existing cobrohead-styie streetllghts within ddwnthwn -
particularly on DuNin Boulevard, arguably its "main street"
spine - are a missed opportunity to project a strong
downtown streetscape image (especially when most buildings
are deeply set back from the street). Use of o decorct;ve
and sites do not. The designs shown use twin roadway
heeds for strong architectural effect, and also provide
pedestrian height heads to indicate that pedestrians are
welcome even though the street space use is primarily
vehicular, In this way, they reinforce both o public
character at roadway and pedestrian scales, Though they
are contemporary In styllstic character, they have detail in
their luminalre heads and bases that "reward" the viewer
upon closer approach.
