INTRODUCTION

All•Merin City
2007-2012.2013
2017*2019
The enclosed resolution provides for the acceptance of the Public Improvement
Construction Contract for the North Cascade Road Reconstruction Project, Phase 1
from the bridge over Catfish Creek to Edval Lane, Iowa DOT Project No. STBG-SWAP-
2100 (669)--SG-31.
BACKGROUND
With the completion of the Southwest Arterial (US 52) and the location of the Middle
Interchange at North Cascade / English Mill Road, traffic volumes are expected to
increase on North Cascade Road. The original roadway was narrow, substandard in
design and was inadequate to accommodate future traffic and development growth.
The Timber Hyrst residential subdivision connects Creekwood Drive to North Cascade
Road between Edval Lane and the Catfish Creek bridge. The original development
agreement for this subdivision between the City of Dubuque and North Cascade Road
Developers, LLC., in addition to a pre -annexation development agreement with Gary
Valentine stipulated that the City was responsible for completing safety related
improvement to North Cascade Road.
DISCUSSION
The North Cascade Road Reconstruction improvement included the reconstruction of
North Cascade Road from the bridge over Catfish Creek to Edval Lane. The previous
24-foot rural roadway was widened to a 35-foot urban "complete street" section with 5-
foot paved shoulders / bike lanes on each side of the road. The previous curves on
North Cascade Road were substandard and were realigned to improve safety and allow
for better sight distance. The project also included grading for future sidewalk and a 10-
foot-wide bike / pedestrian shared use path. The installation of the sidewalk and shared
use path is being deferred to a future date when development occurs along the corridor
and the trail network connects to the bike / pedestrian trail along the Southwest Arterial.
Additionally, the City does not have authority to require sidewalks for the segments of
North Cascade which are within Dubuque County jurisdiction.
WATER MAIN EXTENSION
As part of the North Cascade Road Reconstruction project, the city installed a new 12-
inch water main along North Cascade to Edval Lane. The water main was originally
planned to only be extended to Creekwood Drive; however, the City received very
favorable bid prices for the construction of new water main from the Catfish Creek to
Creekwood Drive. As a result, the City issued a change order (added $160,000) and
amended the construction contract to provide for the extension of the new water main
from Creekwood to Edval Lane with available funds.

The newly installed water main now provides a critical distribution loop connection to
serve the Creekwood Drive Timber Hyrst residential subdivision and is now in a position
to be extended from Edval Lane to the Southwest Arterial corridor to support future
expansion and growth. The additional cost to extend water main to Edval Lane is
summarized below.

NORTH CASCADE ROAD CONSTRUCTION
The North Cascade Road Reconstruction Project, Phase 1 from the bridge over Catfish
Creek to Edval Lane was completed by Top Grade Excavating, Inc. of Farley, Iowa in
the final contract amount of $1,617,366.68 which is an 8.9% increase from the amended
contract amount of $1,484,638.24. The added costs incurred were a result of additional
excavation needed to create a stable rock cut embankment near Miner's Lane
($159,682.96).
RECOMMENDATION
I recommend that the City Council accept the Public Improvements and authorize the
payment of the contract amount of $1,617,366.68 to Top Grade Excavating, Inc., for the
North Cascade Road Reconstruction Project, Phase 1 from the bridge over Catfish
Creek to Edval Lane.

The North Cascade Road Reconstruction Project was the City's first project to be
developed and constructed under the Federal Aid SWAP Policy which will use State
Primary Road funds to reimburse the City for 100% of eligible roadway construction and
property acquisition costs which eliminates the requirement for a 20% local match. All
other associated costs, such as engineering design, contract administration,
construction engineering and inspection are funded solely with City funding.

Improvement Construction Contract and to authorize the payment of the contract
