RE: University Avenue and North Grandview Avenue Roundabout Intersection
Improvement Project
CIP No. 3002724, lowa DOT Project No. STP-A-2100 (689)--86-31
INTRODUCTION
The purpose of this memorandum is to provide the City Council with information related
to the University Avenue and North Grandview Avenue Roundabout Intersection
Improvement Project and request concurrence to initiate the public bidding procedure
and establish the date for the public hearing.
�AC KG Ftt�l�ND
In July of 2016, the City received bids for this intersection and the intersection at Loras
Boulevard and North Grandview Avenue to be signalized intersections.
These proposed signalized intersection improvements were recommended by the
East/West Corridor Study that was formally adopted by the City Council in February
2012.
Because of the positive feedback and the successful operational performance of the
new Grandview-Delhi-Grace Roundabout, Engineering staff considered the possibility of
modifying the proposed signalization project to include a roundabout at the University
Avenue and North Grandview Avenue Intersection. There were several issues that
needed to be overcome before a roundabout could be considered including potential
funding.
City staff discussed the potential revised roundabout concept with the lowa DOT first.
District 6 Local Systems Engineer was supportive of the potential project change and
consulted with the Office of Traffic and Safety, who also supported the concept.
To fund the proposed project, the City pursued grant funding from various sources
including an DMATS STBG Grant, lowa Clean Air Attainment Program (ICAAP) Grant
and Traffic Safety Funds Grant (TSF). The City was successful in acquiring funding for
this project from all three listed funding sources.

DISCUSSION
The project provides for construction of a roundabout at the intersection of University
Avenue and North Grandview Avenue. Engineering staff has been working with
MSA/Ourston on the design of the proposed roundabout. MSA/Ourston is a well-
respected roundabout design firm that has been involved in the design of hundreds of
roundabouts in the United States. MSA/Ourston is one of two consulting firms in lowa
that the DOT uses for peer reviews on roundabout designs. MSA/Ourston designed the
alignment and profile for the roundabout to make sure it properly addresses sight
distance and speed concerns at the roundabout. The roundabout is designed to operate
with vehicles traveling around 15 mph through the roundabout.
Engineering staff used the design model developed by MSA/Ourston to develop the rest
of the construction documents with specific attention to pedestrian access, including
ADA issues, lighting, construction phasing, utility impacts and business access in the
area. Some the physical elements of the roundabout include:
■ 9" doweled PCC pavement to facilitate larger vehicles and accommodate
construction phasing.
■ A colored concrete truck apron to allow oversized vehicles to get through the
roundabout when needed. Most vehicles (including buses) will not need to use
the surmountable truck apron. There is �n aprc�n across from Fire Station No. 4
for turning and backing into the driveway.
■ Four (4) LED street lights to provide lighting at street intersections and cross
walks for good visibility at night.
■ Directional signage to alert drivers to the operation of the roundabout and to alert
them to pedestrian crossing areas.
■ Deflecting splitter islands which divert the traffic so vehicles slow down and are
able to easily blend into the circular traffic pattern.
■ Recycled Purington brick accents along the edges of the project to pay respect to
the former brick streets in the area. There is existing brick under some of the
asphalt pavement in the area.
■ Pedestrian access ramps that are ADA compliant will be installed. There will not
be a cross-walk on the north leg of North Grandview due to sight distance and
ADA slope issues.
■ A Jule Bus pull off lane for the relocated Mid-Town Transfer Station and related
sidewalk and lighting improvements. The Jule Mid-Town Transfer Station is
relocated from North Grandview Avenue south of the intersection to North
Grandview Avenue north of the intersection adjacent to Allison-Henderson Park.
The project will also include some utility improvements. These include the replacement
of 6" and 12" watermain, replacement of 8" sanitary sewer, manholes, replacement of
storm sewer, replacement of two fire hydrants, and the installation of electrical and fiber
optic conduit.

with interested parties at an open house at Holy Trinity Lutheran Church near the
project site. The City and its consultant have prepared FAQ sheets, project fact sheets,
brochures, public information meeting displays, PowerPoint presentations, video
animations of the working intersection, and other information for media releases. The
City also is planning to provide information to business owners to give to their clients
before and during construction. The City also is planning to add information/brochures
to monthly utility billing mailings.
