FROM: Larry Zimmer, Capital Improvements Division Manager
SUBJECT: Presentation of Trestle Rehabilitation Project
RECOMMENDATION
This presentation is intended to inform City Council of the project status and provide an
opportunity for City Council input into the process. No action is requested at this time.
BACKGROUND
The Downtown Trestle begins at the terminus of Western Street, runs along the Water Street side
of the Great Petaluma Mill and the intersection of B and Second Streets, and ends near the Yacht
Club. The 90-year old structure is owned by the Sonoma Marin Area Rail Transit (SMART). In
recent years it has become unsafe for pedestrian use and is fenced off.
In 2002, as part of the River Enhancement Project, CSW/Stuber-Stroeh developed a "Preliminary
Study of the Water Street Trestle Evaluation and Replacement." The CSW report gives an
approximate age, description of the trestle, evaluation of the condition and recommendation to
prohibit pedestrian and vehicular traffic. The report also provides rehabilitation and replacement
schemes, with estimated costs.
Subsequently, City Council desired to establish the historic contributing potential of the trestle
through a formal Historic Structure Report (HSR) process. In 2007, a.PCDC funded Historic
Structure Report was completed to: research the origins of the trestle, create a chronology of
railroad ownership, and perform preliminary engineering and rehabilitation cost estimation for
both pedestrian and trolley loading. The "Treatment Recommendations" section stated that the
pedestrian load would retain more of the trestle's historic fabric and original construction by
wrapping the piles in newer material (polyethylene and/or concrete). Due to the heavier loading,
the trolley load would require a majority replacement of the trestle structure.
On April 20, 2009, the City Council authorized application to the Coastal Conservancy for
funding through the San Francisco Bay Area Conservancy Program. Staff was notified in May
2009 that the California Proposition 84 Bond funding was frozen and the Coastal Conservancy
was not encouraging applications. In late 2009, the Trolley Group provided financial assistance

to develop a detailed scope of work and cost estimate for the Trestle Rehabilitation Project. This
preliminary design work added a higher level of detail and accuracy to the Coastal Conservancy
grant application. By the beginning of 2010, it appeared that funding would be available in the
following months and staff was encouraged to submit the application.
In March 2010, the City submitted a grant application requesting $500,000 for planning and
design of the trestle rehabilitation, including bank stabilization measures, environmental
clearance and necessary permits, and an educational component. The final product for the work
funded by this grant will be construction drawings and specifications. In December 2010, City
Council accepted the Coastal Conservancy Grant.
On December 14, 2011, a public meeting was held to present the process to date, the results of
the preliminary analysis of the trestle structure and three alternative approaches to
rehabilitate/reconstruct the trestle.
To provide a more detailed background it may be helpful to understand the many components of
the trestle. Please see attachment labeled Trestle Existing Pile Bent Elevation, which provides a
graphic representation of the trestle structure.
DISCUSSION
The objective of this project has always been to retain as much of the original structure as
possible in order to maintain the historic integrity of the trestle. Within the consultant's scope of
work are several alternative designs and the associated costs. One of the alternatives, intended
primarily as a comparison, is the full replacement or reconstruction alternative. To create the
other alternatives, a full understanding of the permitting and environmental clearance
requirements, existing condition of the trestle components, geotechnical data, and stakeholder's
concerns were all needed.
Based on past reports it was expected that the cost of constructing the trestle for trolley loading
would be significantly more expensive than pedestrian only loading. However, after further
investigation, it was determined that pedestrian only loading does not change the design
significantly. Since the cost difference is expected to be minor(or non-existent), and rather than
limit future use, all alternatives will be adequate for either, trolley and pedestrian or pedestrian
only loading.
Staff and the consultants considered three general alternatives. Alternative 1 is intended to
maintain as much of the existing structure as possible. Alternative 3 is a full replacement, or
reconstruction of the trestle to appear similar to the original but with more modern materials and
construction methods which will provide for a longer expected life. Alternative 2 is intended to
be a compromise between the other two alternatives, constructing a new trestle support structure
while maintaining, or reusing existing components.
The wood consultant reports that 70% of the piles are in fair to poor condition with significant
section loss due to microbial decay and dry rot. The majority of the piles cannot withstand full
loads. There are several methods for strengthening the existing piles such as steel or reinforced
2
concrete encasement, or sleeves, or a polymer wrap. One of these methods would be used for the
majority, or all of the piles in Alternative 1. Alternative 2, as proposed, would build a new
support structure between the existing bents to bear the weight. This would allowthe existing
piles to remain in place and in their existing condition. In Alternatives 2 and 3, steel piles have
been selected to replace the timber piles for structural integrity, longevity, case of maintenance
and installation. This would be less disturbing to the adjacent businesses rather than pile driving.
Any treated wood utilized in the river is currently required to be coated with polyurethane.
Untreated wood is subject to tide cycles resulting in a shorter lifespan as wood not having the
opportunity to dry completely will rot. Since neither material will appear "historic" staff
recommends the use of steel since it will last significantly longer than polyurethane coated wood.
In all three approaches the existing track would be replaced in its current alignment with as many
ties as are in reusable condition (estimated around 50%) and the deck boards and-joists will be
completely replaced. In Alternative 1, the stringers and.bent caps would be assessed for extent
of deterioration and reinforced or replaced as needed. In Alternatives 2 and 3, the stringers
would be replaced with wood or colored and textured concrete. At this time, the condition of all
the wood components have been assessed by visual means, "sounding" (striking with a hammer)
and some limited resistance testing. All three methods have an objective and scientific approach,
but since all of the components are not accessible to be tested from all angles, and some are not
reachable such as the stringers, reasonable assumptions must be made about their condition. The
actual condition would not be known until the time that the Trestle is dismantled.
City staff, SMART staff, and the design consultants met to discuss the alternatives. The concern
with either of the rehabilitation alternatives (Alts. 1 or 2) is that the modifications necessary to
make the trestle structurally adequate and safe for pedestrians would require such alterations that
its appearance would be drastically and negatively impacted. The consensus opinion was a
replacement(Alt. 3) would provide a far more attractive structure and would appear more similar
to the original design of the trestle. Additionally, replacement would provide a longer life and
virtually eliminate maintenance.
At the December 14, 2011, public meeting staff and the consultant team presented the project
process to date, the three alternative approaches and solicited comments from the attendees. In
summary, all of the attendees were in favor of restoring the trestle in sonic fashion as opposed to
its eventual removal. Opinions differed between the project alternatives and the specific details.
• Alternative 1 was favored by some, since it maintained more of the original materials.
Some were of the opinion this alternative made the structure "ugly" by wrapping the piles
and adding additional structural members. Based on a citizen's comments, this
alternative would be modified from the schematic in the presentation to uniformly treat
the piles to create a consistent appearance. Any added structural members would be
hidden as much as possible behind existing materials. Pile repairs would be done to
minimize the adding additional diameter to the piles.
• Alternative 2 appeared to be the least popular since it added new bents between the
existing ones and as the original structure continued to decay, disappearing over time, a
completelynew trestle differing in appearance from the original would be left in its place.
3
• Alternative 3 was well supported, provided the new materials are made to look as much
like the original wooden structure as possible. Opponents to this alternative wanted to
make it clear that this alternative builds a "replica" with no authenticity, and does not
maintain any of the historical integrity.
The discussion about loss of the original materials led to a discussion about possibly maintaining
some components of original structure. Some suggestions were to keep, or reconstruct one bent
of the new structure out of the original material, use some of the original material as a facade on
the exposed face of a new trestle, rebuild a bent as a monument(separate from the trestle), or use
exiting materials to construct an additional pedestrian connection to the trestle (discussed below).
There appeared to be unanimous agreement at the public meeting that some portion of the
existing structure be saved in some way.
There are several components of the trestle that are mutually exclusive of which alternative is
selected, which were also discussed at the public meeting.
• The railing is not an original component of the structure and since there was no railing
during the active original use of the Trestle, there is no historic material to save and no
design to copy. Current building codes set certain requirements of the railing design
upon the project. At this time, staff is intending continuation of the edge railing installed
a few years ago during the Water Street Plaza project, or something similar to maintain
consistency.
• Some comments suggested the addition of a mid-span pedestrian bridge. Historically, a
spur railroad line split off the Trestle, heading south, approximately between First and
Second Streets, paralleling both. A mid-span bridge could be built in the same historical
configuration or as a new amenity. This addition would allow more pedestrian access,
another safety zone for safe trolley passage and an elevated platform to view the storm
drain outfall. The mid-span pedestrian crossing will be further investigated to determine
feasibility and estimated cost.
• The fender piles are a line of solid timber piles, spaced approximately four feet apart, and
approximately four feet from the Trestle structure. They are not attached to the TreStIO
and most of the connections between each fender pile has deteriorated and disappeared.
The original purpose was to act as a fender to the Trestle, in the same manner as a fender
on a car, when barges and boats docked for goods loading/unloading. Many of these
piles have been tied back to the bank or Trestle as they deteriorate and lean onto the
floating docks. This line of fender piles is visible from across the Turning Basin,
however, they are not required for any structural purpose. These original piles could be
left in place and removed as they become a nuisance. This is not recommended however,
as working around any original materials will impact the construction process. It is
stalls intention to include construction of replacement fender piles, possibly of the same
material as whatever becomes the recommended alternative of the trestle, as an
alternative bid in the construction documents. This will allow City Council to decide on
inclusion of the fender piles at the time of contract award.
4
Staff will use the comments from the public meeting along with City Council comments to
further define the three alternatives. These alternatives, with the additional detail, will be
assessed from an environmental and permitting standpoint prior to completing the environmental
document. Staff will then return to City Council with a recommendation and resolution to
approve a specific alternative and approve the environmental document.
Unless the consensus of Council differs, following is how staff intends to proceed with this
project.
I. Alternative 3 is expected to be recommended along with sonic inclusion of existing
materials in the trestle or in the area. Following are a few possible reuse ideas which will
be investigated:
a. Leave an existing trestle bent in place. It will not be load bearing and will
continue to deteriorate, and will likely require sonic maintenance and will
eventually leave a visual gap in the bent spacing.
b. Save the best of the existing timber stringers and install on the exposed sides of
the trestle.
c. Rebuild a bent apart from the trestle as a monument to the original trestle.
d. Useexisting and new materials to construct a pedestrian crossing at trestle mid-
span.
e. Reuse of existing materials as part of the educational component of the project.
2. Railing will be designed to best match the railing along the river adjacent to the project.
3. Fender piles will be added as an alternate bid.
4. The replacement trestle will be designed with similar spacing of piles and bents to the
original. While the materials used will be per modern construction standards, textures
and colors will modified to appear as close to the original materials as is possible.
FINANCIAL IMPACTS
The project is within the prior approved budget for this phase of the work. The
rehabilitation/reconstruction phase has no funding currently. The Coastal Conservancy may
contribute up to another $500,000 toward the construction phase if they have funding available
and find a subsequent grant application worthy. Staff is constantly seeking grant opportunities
for the future project and identifying.smaller projects within the overall project that could be
grant funded in advance.
It should also be noted that one public comment suggested that Alternative 3 (replacement)
would limit grant funding possibilities since it would make the project ineligible for"historic
restoration" type grants. Staff investigation has yet to reveal any viable funding opportunities
that would be precluded by selecting any specific Alternative.
The Alternatives have estimated construction costs from $3.5 Million to $4.5 Million. In general
Alternative #1 is the lowest cost and Alternative#3 is the highest. 'Ihe estimates will change
significantly as the scope of the construction project is further defined.
