Sealed bids were received by the Iowa Department of Transportation for the Phase 1 of
the Southwest Arterial Project, North Cascade Road Reconstruction Project. City
Engineer Gus Psihoyos recommends award of the contract to the low bidder, C.J.
Moyna & Sons, Inc., in the amount of $1,591,521.32, subject to Iowa DOT approval.
This amount is 21.5% below the estimate of probable cost.
The preliminary engineering design phase was completed in March 2008, and the
Southwest Arterial Project is now proceeding with the final engineering design phase,
right -of -way property acquisition and archaeological and cultural resource phase III
mitigation work.
Due to project funding constraints, the design team has been preparing cost scenarios
and evaluating construction alternatives for completing components of the project with
currently available federal, state and local funding. To maximize available funding, the
City is moving forward with a phased approach that would allow for Southwest Arterial
improvements to be made that would provide immediate public benefit and would
provide significant efficiencies for the future grading and paving of four -lanes between
Highway 151/61 to Highway 20.
The North Cascade Road Reconstruction Project is the first project bid as part of the
Southwest Arterial Project. The project will provide for the reconstruction (grading and
paving) and realignment of North Cascade Road from about 0.6 miles south of the
Storybook Hill Children's Zoo to 0.1 miles north of the zoo. Since North Cascade Road
will be over the top of the future Southwest Arterial, excavation is needed for the future
bridge approach sections. The excavated material will be used to grade a portion of the
future Southwest Arterial Project to the east of North Cascade Road. The project will be
constructed while allowing through traffic at all times.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

The enclosed resolution authorizes the award of the North Cascade Road Reconstruction
Project (Phase I of the Southwest Arterial project), Iowa DOT Project No. HDP -2100 (655)-
-71-31.
BACKGROUND
The preliminary engineering design phase was completed in March, 2008 and the
Southwest Arterial project is now proceeding with the final engineering design phase, right -
of -way property acquisition and archaeological and cultural resource phase III mitigation
work.
Due to project funding constraints, the design team has been preparing cost scenarios and
evaluating construction alternatives for completing components of the project with currently
available federal, state and local funding. To maximize available funding, the City is
moving forward with a phased approach that would allow for Southwest Arterial
improvements to be made that would provide immediate public benefit and would provide
significant efficiencies for the future grading and paving of four -lanes between Highway
151/61 to Highway 20.
DISCUSSION
The North Cascade Road Reconstruction Project is the first project bid as part of the
Southwest Arterial project. The project will provide for the reconstruction (grading &
paving) and realignment of North Cascade Road from about 0.6 miles south of the
Storybook Hill Children's Zoo to 0.1 miles north of the zoo. Since North Cascade Road will
be over the top of the future Southwest Arterial, excavation is needed for the future bridge
approach sections. The excavated material will be used to grade a portion of the future
Southwest Arterial project to the east of North Cascade Road. The project will be
constructed while allowing through traffic at all times.
SIDEWALK & PUBLIC ACCESS
Roadway Classification
Sidewalk/Walkwav
Future Phasing
Requirement
Rural Highway
400 -2000 ADT
5 ft shoulder preferred,
4 ft minimum shoulder
required
Secure /preserve right -of-
way for future sidewalks
Rural /Suburban Highway
ADT > 2000 and less
than 1 dwelling unit per
acre
Sidewalks or side paths
preferred. Minimum of 6 ft
shoulders required.
Secure /preserve right -of-
way for future sidewalks
The U.S. Department of Transportation, Federal Highway Administration (FHWA)
guidelines and priorities for new sidewalks and walkways was reviewed prior to making
this recommendation. The guidelines were commissioned by the FHWA using the input
and expertise of the American Association of State Highway and Transportation Officials
(AASHTO) and the Institute for Traffic Engineers (ITE). The FHWA, AASHTO, and ITE
created a chart for determining when new sidewalks /walkways should be installed. The
considerations for new sidewalk/walkway installation include the type of roadway, the
location, traffic levels, density, connectivity, and accessibility. North Cascade Road is a
rural and /or suburban roadway. A traffic count taken last year resulted in 1,840 average
daily trips (ADT). The area has Tess than one dwelling unit per acre and the nearest
sidewalk is in excess of 1.5 miles from this project. Based on the FHWA, AASHTO, and
ITE chart North Cascade Road would be classified as either:
1) A Rural Highway with 400 -2000 ADT, or
2) A Rural /Suburban Highway with more than 2000 ADT and less than 1 dwelling unit
per acre.
The guidelines for sidewalks /walkways which fall within these classifications are as follows:
In addition to the FHWA guidelines, the Iowa DOT design standards were reviewed. The
Iowa DOT Design Manual addresses sidewalks on rural roadway cross section as follows:
"Sidewalks generally should not be constructed in areas with rural cross sections, that
is, cross sections without curbs. In rare instances when sidewalks are constructed in
these areas, the sidewalk will be constructed at the top of the foreslope, as close to the
right -of -way line as practical."
The realigned section of North Cascade Road, which will cross over the future Southwest
Arterial will be constructed to Iowa DOT rural roadway design standards which will include:
24 -foot roadway; 6 -foot paved shoulders with 4 -foot granular stone shoulders; and 3:1
graded roadside foreslopes. Additional right -of -way outside of the roadway has been
retained.
Any future development and annexation of property into the City of Dubuque along North
Cascade Road which results in a transition of the roadway from rural and /or suburban to
urban would be considered at such time as North Cascade Road is upgraded to meet city
standards and specifications. Federal and state guidelines would be revisited at that time
for the placement of sidewalks.
The design team systematically reviewed each bridge structure on the Southwest Arterial
Project and those on crossing side roads. Each bridge location was evaluated for present
and the potential for future bicycle and pedestrian use.
It was concluded that the future North Cascade Road bridge (over the Southwest Arterial)
would include a 10 -foot wide paved shoulder which would accommodate bicycle and
pedestrian use. Other bridges will include a dedicated separated sidewalk due to the
location of the future bicycle and pedestrian trail that will be constructed as part of the four -
lane phase of the Southwest Arterial.
