MEMORANDUM
August 10,2005
TO:
Michael C. Van Milligen, City Manager
Gus Psihoyos, City Engineer ~
SUBJECT: Rosedale Avenue Reconstruction Project
FROM:
INTRODUCTION
The enclosed resolutions authorize the award of the construction contract for the
Rosedale Avenue Reconstruction Project.
BACKGROUND
The Rosedale Avenue Reconstruction Project will include the complete reconstruction
of the roadway sub-base and pavement, which provides for a 37-foot wide concrete
roadway between West Locust and North Grandview.
The project will be constructed in two phases. Phase I of the project will include the
complete reconstruction of all underground utilities and mainline roadway construction
from West Locust to Glen Oak. The Phase I section of work is anticipated to be
completed by November 23, 2005 and open to local residents and vehicular traffic for
the winter season.
Phase II of the project will include the remainder of the underground utility work and the
concrete roadway construction from the Glen Oak intersection to North Grandview. The
completion for the entire project is scheduled for July 28, 2006.
The existing storm sewer system between West Locust and Glen Oak is aging with
capacity deficiencies and will be completely reconstructed with dual 48-inch diameter
pipes. The remaining storm sewer between Glen Oak and North Grandview will be
upgraded to improve the storm water conveyance in the area.
The existing sanitary sewer system will be completely upgraded to include a new 12-
inch mainline sewer; the reconstruction of deteriorated brick manholes; and the
replacement of all private sanitary sewer laterals. The cost for the individual sanitary
sewer lateral replacements will be assessed to each respective private prop~rty owner.
The watermain system is scheduled for complete reconstruction which will include new
main line water service, valves and fire hydrants. Records indicate there are currently
four (4) lead residential water services to be replaced. The cost for the individual lead
residential water service replacements will be assessed to each respective private
property owner.
The project will also provide for the installation of fiber optics and telecommunications
conduit infrastructure and the complete reconstruction of the existing pedestrian
sidewalks along both sides of Rosedale Avenue between West Locust and North
Grandview.

The Rosedale Avenue Reconstruction Project will be funded through the annual capital
improvement project appropriation of City funds as noted above in the amount of
$686,847.32. Due to overage in the sanitary sewer portion of the bid, additional funding
is necessary to construct the sanitary sewer on the project. This will be financed from
the General Sanitary Sewer Repair Fund in the amount of $13,256.04. The project, as
outlined, will require Special Assessments in the amount of $191,795.27 and
expenditure from the Annual Street Construction Program (Funded through Local
Option Sales Tax) in the amount of $1,011,192.81.
ACTION TO BE TAKEN
I recommend that the City Council adopt the attached resolution awarding the Rosedale
Avenue Reconstruction Project to Portzen Construction, Inc. in the amount of
$1,468,984.70.
