COUNCIL AGENDA REPORT . ITEM NU R:
FROM:
Wayne A. Peterson, City
SUBJECT:
Jennifer St. Pedestrian Bridge - Specification No. 94-03A
CAO RECOMMENDATION:
Authorize Design of the Project to Include a Staircase
DISCUSSION:
On September 19, 1995 Council considered additional design services for
the Jennifer Street Pedestrian Bridge Project. During discussion of the
project, Council had questions regarding the staircase that the Cultural
Heritage Committee (CHC) and Architectural Review Committee (ARC) had
asked to be included in the project. During their review of the project,
CHC and ARC had indicated that they felt the project would better meet
pedestrian needs if a staircase could be provided. Neither body was
insistent that the staircase be built as a part of the project if cost
was an issue. They wanted to be sure that it could be added in the
future if desired. `
Attached to this report is an illustration showing what the bridge would
look like with and without a staircase. Staff agrees that the bridge
would be much more desirable to pedestrians if it could be used without
having to walk up the long ramps that are necessary for ADA and bicycle
accessibility.
ALTERNATIVES:
If cost is an issue, Council can direct that the stairs be bid as an
additive alternate, and that the design be flexible enough to allow the
bridge to be built with or without the stairs.
FISCAL IMPACT:
Design costs and construction estimates were considered at the September
19th City Council meeting. Approval of the CAO recommendation does not
require additional funds for design purposes.
If the Council chooses not to include the staircase, design costs should
be reduced by $3957.00. If the project is built with the staircase, the
architect estimates that it will add $40, 000.00 to the total construction
cost.

SUBJECT: Cost Information for the Jennifer Street Bridge Project
In response to our telephone conversation, I hope you find that the following table provides useful
information. A more detailed enclineers construction cost breakdown can be made available at the
Council meeting if need be.
Please note that the project's total construction cost ($960,000 including the cost of stairs) includes a
20% estimate for "contingencies." The table below also identifies secured funding sources (the first
two lines) and "potential" funding sources for the project. The City Council is scheduled to consider
approving a grant application (involving the potential funding sources) at its November 7th meeting.
Look for a full Council Agenda report and supporting materials in the upcoming weeks.

Re: Pedestrian Bridge
Dear Mr. Mayor,
It seems apparent that the design costs involved with the bridge over the railroad tracks
are getting a bit excessive.
As a tax-paying citizen of this city, may we suggest a prefabricated bridge?
