To: Honorable Mayor and City Council
From: Tom Montgomery
Date: July 16, 2007
Re: Add to Agenda -Change Order, Project 2007-1, 5th St. Area Retaining Walls
Council is requested to add to the agenda consideration of a change order to the 5th Street
Area street and utility reconstruction project for an older looking style of modular block
retaining wall in the Conservation District. This retaining wall question is coming forth
due to the Planning Department's recommendation for a less modern looking retaining
wall within the Conservation District as part of their review of the Deitner retaining wall
on 2nd Street.
The City's standard specifications call for the use of a modern modular concrete
block wall similar to the one proposed by Mr. Deitner. Retaining walls using this modern
modular block were constructed last year as part of the 3rd St. area reconstruction project
within the Conservation District and in 2000 as part of the 4th St. project. This year, as
part of the 5th St. project, the Public Works Department worked with the HPC to review
options for installation of a large retaining wall on Ashland Street, south of 5th St.,
around the Specht house and stairs, which are identified as historically significant. Based
on recommendations from the HPC and the Specht family, the contractor will be
installing a tumbled block wall.
The tumbled block walls are $1.00 per square foot more expensive than the
modern modular block walls, and we estimate that the additional total cost to switch to
these walls for the rest of the project within the Conservation District would cost about
$3,600. If the City wishes to change the type of block walls, the manufacturer will need
authorization to begin making the block by next week in order to keep the project on
schedule.
COUNCIL ACTION REQUESTED
Council is requested to approve a change order to the 5th St. Area Improvement
Project to install tumbled modular block retaining walls in the Conservation District.
