Chili/Chippendale Intersection, Project #179
Our Consulting Engineering firm has made a few revisions in the original
feasibility report based on past discussion with Council. In addition, our
Consulting Engineers traffic engineer, Glen Van Wormer will be present to provide
a brief overview of the feasibility study and answer questions that Council may
have regarding this project.
I met with Mr. Tom Nelson, Director of Support Services, of the School District
regarding this matter. Mr. Nelson indicated that he did not feel the School
District could provide any financial assistance in this project. After hearing
what our Consultant has to say regarding this project, Council might wish to
direct Staff or a Council representative to contact the next level of decision
makers at the School District, that being either the Superintendent or the School
Board, to see if there are any possibilities of the School District providing any
funding assistance for this project and what options we may have to pursue should
this decision making level decide not to authorize any funding for this project.
If Council has any questions or concerns regarding this matter, please feel free
to contact me at Councils convenience.

AUTHORIZATION
The City Engineer/Public Works Director in a letter dated
December 2, 1987 requested the preparation of a feasibility study
for revising the intersections of 145th Street at Chili Avenue
and Chippendale Avenue into a single, four-way intersection. A
work program was submitted to the City on December 21, 1987 and,
following a January 11 meeting, was revised and resubmitted to
the City on January 19, 1988. The report was authorized to
provide information relating to the cost, potential property
impacts and operational considerations associated with the final
improvement to the intersection.
SCOPE
This report is based primarily on a single alternate considera-
tion which is to realign Chippendale Avenue and Chili Avenue to a
single intersection at 145th Street. The intersection of Dodd
Boulevard and Chippendale Avenue would also be realigned to
provide maximum distance between the 145th Street intersection
and the Dodd Boulevard intersection. This study is a follow up
to previous studies, meetings and deliberations by the City staff
and SEH staff relative to operational problems at the existing
intersections. Some conceptual designs have been prepared for
revising the two separate intersections to provide for better
turning radii, providing turn lanes on 145th Street and
relocating the Dodd Boulevard and Chippendale Avenue inter-
section. Operational studies included the potential for
signalization of the two intersections, evaluation of different
methods of stop sign control and a combination of flashers and
warning signs.
After review of the many alternates which are available, it was
felt that a final study of the realignment of the streets to
provide a single intersection would provide the best permanent
solution.
DESI N
GN CONSIDERATIONS
Chili Avenue was constructed in early 1970 as a typical
residential street 32 feet wide. It provides a connection to the
west entrance to Rosemount Senior High School and also provides
access to a residential area. All adjacent residential
properties face the cross streets, such as 143rd Street, but
several have driveways which access onto Chili Avenue.
Chippendale Avenue was formerly County Road 39 and was rebuilt by
Dakota County approximately 10 years ago. In conjunction with
the reconstruction, the intersection of 145th Avenue, Chippen-
dale Avenue and Dodd Boulevard was reconstructed to provide a
single T intersection on 145th Street and a second T inter-
section immediately south with Dodd Boulevard.
145th Street is approximately 40 feet in width east of Chili
Avenue. Through the intersection area, it becomes wider before
ultimately returning to a 24 foot width west of Cimarron Avenue.
The area in the northwest corner of the intersection is largely
an open field and was part of an older farm type development from
which some trees remain. The area in the southeast corner
1 consists of a single family residential unit with a significant
side yard between the building and Chippendale Avenue. There is
a rather large triangle of old right-of-way from Dodd Boulevard
which still remains in the southeast corner.
Traffic volumes on 145th Street east of Chippendale Avenue are
6,200 vehicles per day and west of Chippendale, 5,500 vehicles
per day. In the evening rush hour, volumes are 600 east and 500
west of Chippendale. Morning rush hour volumes are 400 on either
side.
Most traffic on Chili Avenue is associated with the school or the
adjacent residential complex. At times, there is a significant
amount of school bus traffic and school related volumes become
quite high. Chippendale Avenue to the south also carries a
significant volume of traffic as it is a major connector between
145th Street and County Road 42. The importance of Dodd
Boulevard has significantly diminished because of its cul-de-sac
near the County Road 33 and County Road 42 intersections. The
connection of Shannon Parkway between 145th Street and County
Road 42 will further diminish the importance of Dodd Boulevard as
a carrier of traffic.
The close proximity of two major intersections along 145th Street
creates a number of operational problems. The most noticeable
problem is the weave made by traffic which utilizes both
Chippendale Avenue and Chili Avenue. The weaving movement
requires traffic to pull out into 145th Street, accelerate and
then quickly decelerate to make a left turn to the other street.
This start and stop maneuver in heavy traffic can lead to some
driver confusion and potential accidents.
There is also potential, and sometimes realized, congestion which
reaches from one intersection to the other. In the morning rush
hour, left turning traffic to go north on Chili Avenue forces
some backup of traffic to and sometimes through the Chippendale
Avenue intersection. The reverse is true for evening rush hour,
left turning traffic to go south on Chippendale can back up to
the Chili intersection.
A third concern with the split in the intersections is the
pedestrian paths. Some pedestrians utilize the south side of
145th Street to eventually cross at the east side of Chili
Avenue. Other pedestrians cross on either the east or west side
of Chippendale Avenue. Occasionally, pedestrians will cross
between the intersections taking advantage of either a gap in
traffic or stopped traffic.
There is also backup on both Chili Avenue and Chippendale Avenue
caused by either the offset or the heavy traffic movements. it
is
very difficult to make a southbound left turn in the morning
rush hour. Any left turn will significantly backup traffic
because of the lack of gaps in both eastbound and westbound
traffic on 145th Street. Similarly, northbound traffic on Dodd
' Road has a difficult time making a left turn because of the
backup of eastbound traffic from Chili Avenue and the restricted
sight distance this backup creates. The backup on Chippendale
Avenue will occasionally completely block the Dodd Road inter-
section. Similarly, the lines of traffic on Chili Avenue in the
evening rush hour can extend back and block 144th Street.
The City recently installed stop signs on 145th Street stopping
westbound traffic on Chili Avenue and eastbound traffic on
Chippendale Avenue. This temporary measure has reduced some of
the congestion which has occurred on 145th Street, primarily as a
result of backups associated with left turns from 145th Street.
However, this measure also creates some driver confusion because
of the unusual arrangements of stop signs. Motorists who
approach an intersection see a stop sign for one conflicting
movement and assume that the opposite conflicting movement also
has a stop sign. This obviously is not true for southbound Chili
Avenue traffic since the westbound traffic stops but the east-
bound does not. A supplementary sign beneath the stop sign has
attempted to alert motorists to this abnormal situation. This
temporary stop sign measure also does not reduce the weaving
problems, only slightly reduces some of the accelerate/decelerate
concerns and problems, and has no impact or possibly even a
negative impact on pedestrian movements by leading pedestrians
into a false sense of security.
s
PROPOSED IMPROVEMENTS
It is, proposed to revise the intersections to a single four-way
intersection on 145th Street. A conceptual alignment is shown in
Drawing No. 3. Chippendale Avenue is slightly relocated to the
east and a single curve south of Dodd Boulevard will permit the
relocation of the centerline of the intersection approximately 50
4 -
feet to the east. The angle of the intersection of 145th Street
and Chippendale Avenue would be approximately 70 degrees. The
relocation to the east will require some additional right-of-way
in the corner of the property.
By creating a single intersection, a 4 -way stop sign control can
be installed. This would eliminate the existing potential driver
confusion with the current split stop sign controls. It will
also eliminate a portion of the turning movements now being made
and all of the weaving movements between Chile Avenue and
Chippendale Avenue.
Dodd Boulevard would also be relocated further south to a new
intersection on Chippendale Avenue. A single curve on Dodd
Boulevard would result in Dodd Boulevard being realigned to an
east/west alignment at the new intersection with Chippendale
Avenue. The angle of intersection would also be 70 degrees.
A reverse curve would be constructed for Chili Avenue between
144th Street and 145th Street. This would permit the realignment
to match the relocated centerline of Chippendale Avenue. A
tangent section would be provided at both the 145th Street and
144th Street intersections.
The width of revised Chippendale and Chili Avenues would be
increased to provide for two lanes of approach to 145th Street
from both northbound and southbound directions. The additional
width would be necessary to provide for turning movements and, in
the case of Chippendale Avenue and Dodd Boulevard, would provide
for a bypass of left turning traffic.
The trails system on the west side of Chili Avenue would have to
be relocated along with the roadway. The trail would remain on
the west side of Chili Avenue between 144th Street and 145th
Street. A marked crossing should be placed on the west side of
the intersection crossing 145th Street. The east/west trail on
the south side could be extended across the south approach.
RIGHT OF WAY AND EASEMENTS
Right-of-way will be required from three separate parcels for the
proposed improvement. A small triangular area of the property in
the southeast corner will be required for the realignment of
Chippendale Avenue. A triangle of property will also be required
from the side yard of the single family residence in the
southeast corner of the intersection of Chippendale Avenue and
Dodd Boulevard. This also will be a relatively small area.
A major acquisition of right-of-way will be required for the
relocation of Chili Avenue. This taking will remove a signifi-
cant portion of the buildable area which is now vacant. As part
of the right-of-way acquisition, the existing driveway from the
inplace residence should also be relocated to Chili Avenue.
In conjunction with the acquisition of right-of-way, some
additional right-of-way could be available for return to private
ownership. However, in addition to storm sewer, there are
several other public and private utilities which exist under
Chili Avenue, Chippendale Avenue and Dodd Boulevard. The return
of property to private ownership would therefore be subject to
easements for utilities and it is doubtful that any buildable
1 lots or additional buildings on existing lots could be provided.

The project
area is presently served by
an inplace storm sewer
system which
collects storm runoff along
Chili Avenue north of
145th Street and transmits the flows
to the south along
iChippendale
Avenue as shown on Drawing
No. 3. The proposed
improvements
would require the removal
of the inplace catch
basins and
leads at 145th Street and
Chili Avenue and the
construction
of new catch basins and
leads which would be
connected to
the inplace system. The new
facilities are shown on
Drawing No. 3.
RIGHT OF WAY AND EASEMENTS
Right-of-way will be required from three separate parcels for the
proposed improvement. A small triangular area of the property in
the southeast corner will be required for the realignment of
Chippendale Avenue. A triangle of property will also be required
from the side yard of the single family residence in the
southeast corner of the intersection of Chippendale Avenue and
Dodd Boulevard. This also will be a relatively small area.
A major acquisition of right-of-way will be required for the
relocation of Chili Avenue. This taking will remove a signifi-
cant portion of the buildable area which is now vacant. As part
of the right-of-way acquisition, the existing driveway from the
inplace residence should also be relocated to Chili Avenue.
In conjunction with the acquisition of right-of-way, some
additional right-of-way could be available for return to private
ownership. However, in addition to storm sewer, there are
several other public and private utilities which exist under
Chili Avenue, Chippendale Avenue and Dodd Boulevard. The return
of property to private ownership would therefore be subject to
easements for utilities and it is doubtful that any buildable
1 lots or additional buildings on existing lots could be provided.

The driveways for the two residences on the east side of Chili
Avenue will need to be extended. The driveway for the property
on the southeast corner of Chili Avenue and 144th Street would
need to be extended a short amount because of the curve in Chili
' Avenue. The driveway extension for the residence on the
northeast corner of Chili Avenue and 145th Street would be
' increased by approximately 60 feet.
COST ESTIMATE
The construction cost of the relocation of Chili Avenue,
Chippendale Avenue and Dodd Boulevard is estimated to cost
approximately $90,000. This does not include easement
acquisition costs or costs for any relocation of utilities,
' assuming that all would be left inplace except those which must
be moved for construction.
