FISCAL IMPACT
Capital costs are covered by currently committed/budgeted Federal Congestion
Management & Air Quality funds (CMAQ), Measure C funds, Redevelopment funds, and
transportation impact fees. The facility will require maintenance,which costs may be bome
by a variety of sources including the East Bay Regional Park District, County Road funds,
and precapitalized maintenance funds via the Redevelopment Agency. An element of the
final design program is to identify the maintenance costs of design alternatives, and the
appropriate source of funding.
BACKGROUND/REASONS FOR RECOMMENDATIONS
The 1998 Amendments to the Pleasant Hill BART Station Area Specific Plan included a
provision for a pedestrian and bicycle overcrossing at Treat Blvd, of the Iron Horse Trail(see
Exhibit A). The overcrossing is part of a larger set of improvements in the Pleasant Hill
BART Station Area to facilitate non-motorized vehicle circulation, i.e., pedestrian and bicycle
access among others. The Pleasant Hill BART Specific Plan also includes goals and policies
that further define the objectives of the overcrossing program (see Exhibit B).
In the Summer and Fall of 2000 the Redevelopment Agency undertook a Community Design
Program for the Pedestrian and Bicycle Overcrossing Program. The results of this
Community Design Program are summarized in Exhibit C. The community design process
suggests design directions, which will need to be refined in the final design phase. The
Pleasant Hill BART Steering Committee has reviewed arid recommends acceptance of the
Pedestrian/Bicycle Overcrossing Community Design Report.
The siting and appearance of the Iron Horse Trail Overcrossing was also a topic integrated
into the recently completed Pleasant Hill BART Design Charrette. The alternative design
programs under consideration were rendered using computer aided graphics(see Exhibits D-
1 and D-2).
The plan of finance for the Iron Horse Trail Overcrossing is a combination of Federal, local
Measure C funding, Agency funds, and transportation impact fees. Currently committed
funds are:
Congestion Management & Air Quality (Federal) funds $500,000
Measure C funds $1,000,000
Transportation Impact fees/ $1,000,000
Redevelopment funds $2,500,000
The continued availability of the Federal CMAQ funds are based on the County showing
progress in obligating the funds. A September 30, 2001 date for obligating funds and
showing significant progress in achieving final design and required environmental clearance
is approaching. The recommended actions will allow the County to show progress in
obligating these funds.

Pleasant Hill BART Specific Plan Goals and Policy for the Iron Horse Trail
Pedestrian/Bicycle Overcrossing Program (excerpts).
• Transportation and Circulation Objectives:
❖ Provide for safe and convenient pedestrian and bicycle movement
between the BART Station, Station Area parking, local transit
boarding areas, and major facilities in the Station Area and
between the Station Area and nearby residential and commercial
areas.
•:• Provide for the integration of proposed regional trail systems within
the former Southern Pacific Railroad right-of-way into and through
the Station Area.
• Pedestrian and Bicycle Circulation Policies:
•:• Bicycle and pedestrian circulation shall be provided through the
Station Area. Bicycle and pedestrian circulation shall be safe and
shall, to the extent possible, minimize conflicts with other
transportation modes. Adequate, convenient and safe bicycle
parking shall be provided. An interior circulation route will be
provided which accommodates pedestrians and, to the maximum
extent possible, bicycles. The alignment of the interior circulation
route shown will be determined in the review and approval of site
plans for each subarea.
•:• A pedestrian and bicycle overcrossing at Treat Blvd. in the vicinity
of Jones Road for Iron Horse Trail circulation is included as part of
this Specific Plan. The County, through its Redevelopment
Agency, will pursue proceeding with construction to address safety
concerns, and subject to funding availability. Redevelopment
funding shall be combined with other funding to achieve financial
leverage.
•:• A pedestrian and bicycle overpass should be provided at Jones
Road for the Iron Horse Trail, provided that the County Board of
Supervisors, in approving the project determine that, among other
requirements, the form, height, mass, and setback of the Iron
Horse Trail overpass is aesthetically and functionally consistent
with its proximity to the existing office building at 1400 Treat Blvd.
The convenience of pedestrian access to this building at the Treat
Blvd. frontage shall also be provided for in the design of the
overpass. Location and design of the bridge shall be reviewed and
approved by the County Planning Commission after a public
hearing.
•:• Pedestrian and bicycle access shall be provided to the Iron Horse
Trail along a 20 foot wide easement in the former Southern Pacific
Railroad right-of-way to Monument Blvd. with connections provided
to the BART Station, and to Area 11/12. Separate trail rights-of-
way shall be used to the maximum extent possible, but only until
the trail is located within the boundaries of the former SP right-of-
way, which shall occur as soon as feasible. Sidewalks may be
used for temporary connecting segments of the trail on a temporary
basis. The trail should provide for connections to adjacent
development areas and to the Del Hombre Respite Area.
•:• Undertake a Community Design Program for both pedestrian and
bicycle overcrossings as soon as feasible given the availability of
funding and reasonably defined site geometrics. The Community
Design Program would result in preliminary design(s) for the
overcrossing sufficient to secure competitive funding.

Contra Costa County Redevelopment Agency Pleasant Hill BART Pedestrian/Bicycle Overcrossing Community Design
Program
1 EXECUTIVE SUMMARY
Two sites for pedestrian/bicycle over-crossings on Treat Boulevard were identified in the
Pleasant Hill BART Station Area Specific Plan: at Oak Road and at.Jones Road. The Oak Road
crossing would provide a pedestrian link between the fully developed parcels within the block
bounded by Treat Boulevard,Jones Road and Oak Street to the south and the planned
development on the existing BART parking lot to the north. At Jones Road the crossing will
separate Iron Horse Trail cyclists and pedestrians from the Treat Boulevard corridor.
Contra Costa County's Redevelopment Agency appointed the design team of Ove Arup&
Partners, MacDonald Architects and Moore, lacofano and Goltsman, Inc. to undertake a
community design program aimed at gaining a consensus for the aesthetics and amenities of the
overcrossing facilities. Three public meetings were held between June and October of 2000.
The meetings progressed from soliciting the public's goals and general preferences to their
commenting on specific designs and voting to establish a ranking of the final schemes. Meeting
notes, comments cards, and wall graphics were converted into summary reports.
As the developers formulate their plans on each side of Treat Boulevard, the environs around
the proposed Oak Street crossing will undergo unknown but significant changes. These
developers are expected to fund the design and construction of the Oak Road Bridge. With the
arch itectural'unknowrts and the eventual direct involvement of the developers, the design team
created an indicative scheme for the public and devoted the bulk of the design effort towards the
Jones Road crossing. The indicative design at Oak is a steel vierendeel truss that spans from
stair and elevator towers at each end to a center support in the Treat Boulevard median. The
rough construction cost of the structure is S 1.09 million.
The Iron Horse Trail over Treat Boulevard requires ramps for cyclists and the disabled to reach
the bridge deck. Long linear ramps were selected over corkscrew or switchback ramps due to
the many utilities, easements, and space constraints in the area. The trail alignment was also
moved west to provide greater separation from the John Muir Mount Diablo Health Systems
Systems facility and to preserve a stand of mature trees along Jones Road. This shift will take
the right turn lane on Jones Road accessing eastbound Treat Boulevard. As an alternative to
taking the lane,the road could shift to the west by taking advantage of on easement on the
property fronting the south side of Jones Road.
Three designs were presented to the public; a two span concrete girder bridge known as
"Rolling Hills", a single span steel bowstring truss referred to as the "Railroad Arch"and a
single tower steel Cable-stayed bridge.. Two votes were held with the audience in the final
public meeting. The first vote was immediately after a presentation of the three designs; the
second was after an open discussion of the designs amongst the audience and with the design
team. The Railroad Arch won the first round of voting by a considerable margin over the
second place Rolling Hills and third place Cable-stayed schemes. In the second vote the Rail
option was still the leader but the margin of victory shrank with the Cable-stayed coming in a
close second and the Rolling Hills option sinking to a distant third. The Cable-stayed scheme
attracted support as the public gained more information and comfort with the design.
Rough design and construction costs were generated for the Railroad Arch and the Cable-stayed
schemes. The rail bridge is estimated to cost $2.26 million and the cable-stayed is $2.43 .
million. There is some urgency to advancing the design as certain funding sources have sunsets.
Recommendations for work that can start without selecting the final scheme include site survey
with utility locations, geotechnical exploration, right-of-way investigations, and some civil
engineering tasks.
