Approve Design - Lake Street Bridge Replacement, Project 99-03; and Approve
Engineering Services Contract Change Order
Proposed Action.
Staff recommends adoption of the following motion: Move that Council approve the final
desian for the Lake Street bridae replacement. as presented. and approve an
enaineerina services fee chanae order for an amount not to exceed $7.000.
Overview.
In May, 1997 City Council adopted a resolution which committed the city to replacing
the Lake Street bridge in the year 2000. The resolution was required in order to secure
State Transportation Bond funds. In April, 1999 Council authorized a design services
agreement in the amount qf $84,500 with SRF Consulting Group, Inc. Design work has
been completed and staff is requesting approval in order to proceed with advertisement.
SRF has requested an additional $7,000 in fees to cover the costs of additional design
work beyond the bridge approaches, namely roadway edge and sidewalk layouUdesign,
and additional hydraulic analysis effort required by Minnehaha Creek Watershed
District.

Analvsis of Issues.
Primary Design Elements. The new bridge will include a 36' wide roadway with 6'
wide sidewalk on both sides adjacent to 8" high curbing. At the outside edge of the
sidewalk there will be a 2 % foot high concrete base topped with a 2 % foot
ornamental metal railing. The four concrete end sections will each include a
decorative street light. New sidewalk is proposed on both sides of lake Street, both
east and west of the new bridge. The new walk west of the bridge will run to Slake
Road; east of the new bridge it will run to Murphy Avenue on the north side of lake
Street and to the existing sidewalk on the south side of lake Street. Curb, gutter
and a raised boulevard area will be used to define the roadway and pedestrian way
from the bridge to Slake Road. Water and sewer utilities will also be upgraded as a
part of the project. There will be new creek crossings for both utilities in carrier pipes
under the new bridge.
. Neighborhood and business input. Staff held a neighborhood meeting on
October 6, 1999 - four residents living along the north side of lake Street near the
bridge attended. The residents were generally pleased with the bridge design. The
residents stressed the need for improved pedestrian access from the neighborhood
to Slake Road. In addition, staff met with Kathy Forester, CSI General Manager
regarding the roadway changes between the bridge and Slake Road. She agreed
with the design to better define the roadway and the access to their building.
Project budget. The CIP shows a project budget of $405,000. The actual project
cost, including engineering will probably be closer to $500,000. The city's
contribution from the general fund PIR account will increase from $75,000 to
$100,000.

Hopkins, Minnesota 55343
SUBJECT: LAKE STREET OVER MINNEHAHA CREEK
BRIDGE NUMBER 27 A57
SP No. 132-080-01
Dear Steve:
Based on your request, we have developed a fee to perform additional work to prepare sidewalk
plans from the Lake Street Bridge to Murphy Avenue. The fee to perform this task is $3,000.00.
We are also requesting additional fees to perform additional hydrologic analysis requested by the
Watershed District. The Watershed District is requiring an analysis of the impacts upstream and
downstream based on modifications in the bridge hydraulics. This analysis will provide
documentation comparing the existing and proposed bridge for District approval for permits.
Although we did indicate in our proposal that such work may be required, it was identified as
Task 8, Optional Services - $3,000.00.
The Watershed District has given us more detail requirements of what they are requiring and,
based on this, we are requesting an additional fee of $4,000.00 for this work.
Therefore, the total requested fee is $7,000.00. If you have any questions or need additional
information, please call.
Sincerely,
?;;~~~
Larry A. Erickson, P .E.
