CH 21 Study Findings and Recommendations
The Project Management Team (PMT) has developed recommendations for a
combination of concepts to be the Preferred Alternative for CH 21 through Prior Lake.
These recommendations were presented to the Citizens Advisory Committee (CAC) on
July 6, 2004 and are depicted on the recommended concept drawings (notes on the
drawings have been updated and are now dated September 2, 2004).

Expected growth in housing, population and jobs in Prior Lake and surrounding
communities will continue to increase traffic demands on CH 21 and on TH 13
through Prior Lake. 2025 forecasts suggest a doubling of traffic demands
compared to tOday's volumes (2002 ADT of about 11,700 growing to 23,400 vpd
in 2025).
CH 21 is a Minor Arterial within the regional system providing one of only a few
east-west travel opportunities around or past area lakes, parks and other
geographic constraints.
Expansion and improvement to alternative routes will contribute to serving traffic
growth but will not provide sufficient relief on CH 21 to allow consideration of
reducing the number of through-lanes.
Increasing traffic demands over time will exacerbate safety and operational issues
that are experienced on the roadway system today. The "do nothing" approach is
not a prudent course of action.
Access management has been proven to be one of the most effective ways to
improve safety and preserve capacity on arterial roadways.
Two through-lanes in each direction should be provided on CH 21 throughout the
study area.
A center median should be provided to separate eastbound and westbound
through lanes, enhance pedestrian crossing safety and to enhance left turn safety
by providing protected left turn lanes at locations that satisfy access spacing
guidelines or where alternative left turn access cannot otherwise be provided.
Provide right turn lanes on segments of the CH 21 corridor posted at 40 mph or
higher or where right turn traffic demands dictate on low speed segments.
Provide a continuous pedestrian walk on one side of CH21 and a continuous trail
on the other side.

Provide signalized intersection control where appropriate. Specifically, signals
should be planned for, and installed as justified in the future, on CH 21 to serve
full access to the downtown area north and south of CH 21 and with signals on
CH 21 at TH 13, at Franklin Trail, at Fish Point Road, and at CR 87/Revere Way.
11.
Providing capacity improvements at the intersection of CH 21 and TH 13 is
critical to safe and efficient operation of both roadways. Right turn lanes and
double left turn lanes and are needed on each approach to the intersection.
12.
Capacity improvements on TH 13 should be planned for. Forecast traffic demands
suggest that two through-lanes will be needed in each direction in the long term.
13.
Mn/DOT does not have financing for TH 13 in their long range plan but should be
encouraged to plan/program TH 13 improvements and support local efforts to
secure Federal funding resources.
14.
High traffic speeds are a concern that has been repeatedly raised by the
community. Land uses, density and development setback distance from the
roadway are factors that influence speed. CH 21 west of TH 13 should be planned
for low speed operation as compared to segments east of TH 13 where higher
speeds are appropriate.
15.
Pedestrian crossing safety will be enhanced by the proposed center median
throughout the length of the corridor. Crosswalks across CH 21 would be marked
at signalized locations. Pedestrian crossing treatments at other locations where
demand exists should be considered. However, recent pedestrian safety studies by
the FHWA have shown that signing and pavement markings alone do not improve
pedestrian safety on high volume or high speed roadways. The effectiveness of
new technologies and new warning systems for pedestrian crossings are being
evaluated by Mn/DOT. Selection of the appropriate crosswalk warning treatment
should be done when project is ready for implementation.
16.
Storm water control facilities and locations should be identified. Right of way
should be preserved within the corridor.

Corridor Issues Yet to be Resolved
General consensus has been achieved for the long term plan for most of the corridor.
However several very important issues remain. The project management team is working
to gain consensus or to develop information from which informed decisions can be made.
West End (Highland Avenue to Duluth Avenue)
· Access to peninsula properties immediately west of the Wagon Bridge
· Pedestrian crossing treatments and/or parking for anglers closer to the DNR
fishing pier
Downtown Area (Duluth Avenue to Franklin Trail)
· Main Avenue as primary access from CH 21 (Concept D 1) versus Arcadia
Avenue as primary access (Concept D4) to downtown in the long term
a. Concern for reduced downtown access at Main Avenue Access from CH
21
b. Concern for access from TH 13 to Dakota and Pleasant
Short term operational plans - are there any temporary improvements that should
be considered that would effectively serve needs until long term plan is
implemented (suggestions have included a temporary signal on CH 21 at Main
Avenue)
· Continuity of Local Collectors/Relievers to TH 13 and CH 21 (Duluth Avenue)
East End (Franklin Trail to CR 87)
· Possible implementation/staging of improvements
a. Left turn lanes and/or signal improvements at Franklin Trail would be
beneficial now. Consider improvements in advance of bigger project.
bo
Left turn lanes and a new traffic signal at Fish Point Road would be
beneficial in the short term. Consider improvements in advance of bigger
project.
Overall Corridor Issue
Storm water control and treatment - Need to identify storm water ponding
locations and water quality treatment measures. Ponding locations may require
right of way outside of the roadway corridor.
