NARRATIVE
Existing Conditions
The project includes improvements to the intersection of Hickman Road (U.S. Highway 6) and
Berkshire Parkway/SE Waco Place in the cities of Clive and Waukee. The limits of the project
extend just past the existing turn lanes of the intersection.
The current U.S. 6-Hickman Road (east and west approaches) is a U.S. Highway consisting of two
through lanes with a center median and right and left turn lanes at each approach. On the westbound
approach of U.S. 6-Hickman Road the left and right turn lanes include approximately 200 feet and
150 feet of storage, respectively. The eastbound approach of U.S. 6-Hickman Road includes a left
turn lane of approximately 160 feet and a right turn lane of approximately 110 feet. The speed
limit on U.S. 6-Hickman Road is 50 MPH.
Berkshire Parkway (north approach) is a neighborhood collector in the City of Clive. At the
intersection it is a two lane facility with a center median. There are right and left turn lanes in the
southbound direction of approximately 110 feet. The next closest intersection is located
approximately 360 feet north of the study intersection. The speed limit on Berkshire Parkway is
25 MPH.
SE Waco Place (south approach) is a major collector in the City of Waukee. It is a two lane divided
street with left and right turn lanes in the northbound direction at the intersection. The right turn
lane at the intersection with U.S. 6-Hickman Road is approximately 140 feet. The left turn lane on
SE Waco Place is approximately 290 feet. The next closest intersection is located approximately
440 feet south of the study intersection. The speed limit on SE Waco Place is 35 MPH.
The Raccoon River Valley Trail (RRVT) travels parallel to U.S. 6-Hickman Road through the
cities of Clive and Waukee. The RRVT crosses the north approach of the intersection at a
designated trail crossing located south of the median. Trail “Yield” signs are located at each trail
approach of the crossing. A City of Waukee trail is located west of SE Waco Place and has a curb
cut leading to a non-designated crossing U.S. 6-Hickman Road. The north-south trail crossing
location traverses the center raised median on U.S. 6-Hickman Road, but no pedestrian refuge is
currently accessible.
Refer to the 2020 Traffic Signal Warrant Study for additional detail on existing conditions of the
corridor.
Traffic Data
Turning movement counts were collected by Snyder & Associates between June 3, 2020 and June
5, 2020. Due to the on-going Covid-19 pandemic, the turning movement counts were adjusted
using Iowa DOT traffic count factors to determine appropriate traffic volumes at the study
intersection. Collected turning movement counts and adjusted traffic volumes are attached. Based
on these counts the average daily traffic on Hickman Road is approximately 31,000 vehicles per
day. SE Waco Place carries approximately 2,100 vehicles per day and Berkshire Parkway carries
approximately 1,800 vehicles per day.

Crash History
Crash data for the most recent five-year period (2015- May 22, 2020) was collected for the study
intersection from the Iowa DOT – Iowa Crash Analysis Tool (https://icat.iowadot.gov/). During
that time period, 29 crashes were reported, including 1 serious injury crash, 9 minor injury crashes
and 6 possible/unknown crashes. The injury crashes included 1 serious injury, 10 minor injuries,
9 possible injuries, and 2 unknown injuries.
The predominant crash types along the corridor were broadside (15 crashes); angle, oncoming left
turn (5 crashes); non-collision, single vehicle (4 crashes); and rear-end (3 crashes). In general, the
most common crash types were as a result of running a stop sign, failing to yield the right of way,
or other driver errors.
MUTCD Analysis
The 2020 Traffic Signal Warrant Study analyzed the potential for the intersection to meet the
criteria for traffic signalization. As concluded in the study, the intersection currently meets Warrant
1 (8 hour volumes), Warrant 2 (4 hour volumes), and Warrant 3 (peak hour volumes). Warrant 7
(crash experience) was also examined, but was determined to not be met by current conditions at
the intersection.
Proposed Improvements
The proposed improvements include installing a traffic signalization at the intersection to improve
safety for vehicles turning from the minor approaches as well as pedestrians and bicyclists crossing
U.S. 6-Hickman Road. The traffic signals would be interconnected and coordinated wth the
existing traffic signal system along U.S. 6-Hickman Road. Improvements would also include the
extension of left and right turn lanes on U.S. 6-Hickman Road to accommodate additional storage
capacity and safe deceleration at the intersection. Pedestrian and bicycle crossing treatments would
be addressed to improve safety for the Raccoon River Valley Trail users as well as pedestrians and
bicyclists travelling between Clive and Waukee.
The 2020 Traffic Signal Warrant Study examined the potential to convert the intersection from
two-way stop control to traffic signalization. In addition to the 2020 Warrant Study, the Iowa DOT
2018 US Highway 6 Corridor Study identified this intersection as a potential future traffic signal
location. A Cooperative Agreement between the Iowa DOT, the Cities of Waukee and Adel, and
Dallas County for access management for U.S. 6-Hickman Road identified the intersection as
“Future Full Access – May Be Signalized.”
The improvements to the traffic signal system will also provide new opportunities for traffic signal
coordination between the cities of Clive and Waukee along U.S. Highway 6.
