INTRODUCTION
The enclosed resolutions authorize the public bidding procedure for the Northwest
Arterial / Chavenelle Intersection Left Turn Lane Improvements Project.
BACKGROUND
Based on the determination to not incorporate a temporary traffic signal at the US20 -
Seippel intersection as part of the Southwest Arterial Menards Frontage Road (37) and
the Southwest Arterial US20 Interchange Grading (38), the selection of an alternate
detour route was required.
In order to facilitate the upcoming Southwest Arterial Menards Frontage Road (37) and
the Southwest Arterial US20 Interchange Grading (38) construction projects, both Iowa
DOT and City staff evaluated detour route options, and it was collectively determined
that a local road detour using the Seippel Road to Chavenelle to the NW Arterial route
was the preferred alternative.
EXISTING CONDITIONS
In further evaluating the proposed detour route, current operational issues were raised
at the existing Chavenelle - NW Arterial intersection. The existing northbound NW
Arterial dedicated left turn lane onto Chavenelle is approximately 120' in length and is
currently under capacity with left turn traffic movements regularly backing up into the
inside northbound thru-lane. Based on existing conditions, the left turn lane onto
Chavenelle does not have adequate que storage length to support the additional traffic
volumes generated from the proposed detour. See the attached photos which document
the current left turn traffic movements backing up into the inside northbound thru-lane.
The City also reviewed and identified capacity issues with the existing Chavenelle
shared right turn lane onto the NW Arterial. With the outside eastbound lane on
Chavenelle at NW Arterial being a shared thru and right turn lane, when vehicles are
stopped and occupy the straight thru lane, vehicles are unable to make the free right
turn movement. With the right turn being a heavy traffic movement with the proposed
detour, the shared thru and right turn lane will experience backup and congestion
issues. See the attached photos which document the current capacity issue with the
shared thru and right turn lane.
PROPOSED TURN LANE IMPROVEMENTS
Based on the current operational and capacity challenges the City is experiencing at the
Chavenelle and NW Arterial intersection, the proposed left turn lane improvements
include extending the existing northbound NW Arterial left turn lane onto Chavenelle to
an approximate 400' storage length, while also adding a new Chavenelle left turn lane
onto the NW Arterial, providing an approximate 210' storage length. The new left turn
lane would allow for a dedicated straight thru lane as well as a dedicated right turn lane
which would allow right turn overlap phasing which would improve the efficiency of the
detour route. Attached is an aerial exhibit which shows the existing conditions and the
proposed turn lane improvements.
PROJECT SCHEDULE
The schedule for the project is as follows:
Initiate Public Bidding Process September 6, 2016
Publish Notice to Bidders, Advertise for Bids September 9, 2016
Notice of Public Hearing on Plans & Specifications September 9, 2016
Public Hearing on Plans & Specifications September 19, 2016
Receipt of Bid Proposals (Bid-Letting) September 22, 2016
Award Construction Contract October 3, 2016
Project Completion Date November 18, 2016
RECOMMENDATION
I recommend that the City Council establish a date for the public hearing and authorize
the City Clerk to advertise for proposals.
BUDGETIMPACT
The estimate of probable cost for the recommended turn lane improvements are
summarized in the following table:
Description Cost Estimate
Construct - NW Arterial (NB) Left Turn Lane Extension $ 105,000
Construct - Chavenelle New Left Turn Lane 126,000
Contingency (10%) 23,000
Engineering Design and Administration (15%) 38,000
Total Construction Cost Estimate $ 293,000
Based on collaborative discussions with Iowa DOT District 6 staff, it was recommended
that the City request U-STEP funding to cover a portion of the estimated costs for the
left turn lane improvements. Based on the U-STEP funding requirements, the Iowa DOT
would cover 55% of eligible construction costs, up to a maximum of $200,000. The City
would be responsible for 45% as local match. The City will also be responsible for the
engineering design and construction administration related costs.
The proposed project funding is summarized as follows:
CIP No. Fund Description Fund Amount
3002695 U-STEP Funds $ 140,000.00
3002695 NW Arterial Left Turn Lane 153,000.00
Total Project Funding $ 293,000.00
The NW Arterial Left Turn Lane (CIP 3002695) funding is a reallocation of funds from
the Heeb Street - street construction project (CIP 3002612). The section of Heeb Street
(near Kaufman Ave.) was budgeted and scheduled to be reconstructed in conjunction
with planned underground water and sanitary sewer projects. However, funding for the
respective water and sanitary sewer projects has been delayed while staff evaluates
SRF funding alternatives. New funding will be re-budgeted to cover the Heeb Street
construction portion to align with future water and sanitary sewer SRF funding.
ACTION TO BE TAKEN
The City Council is requested to establish the date of the public hearing and to
authorize the City Clerk to advertise for proposals through adoption of the enclosed
resolutions for the Chavenelle / NW Arterial Turn Lane Improvements Project.
