ALTERNATIVE ANALYSIS
PURPOSE OF�STUDY
The purpose of this Alternative Analysis is to select a preferred alignment for 'CSAH J 18
(82nd Street /Lyman Boulevard) between CSAH 13 (Bavaria Road) and TH 41. The existing
"connection" is a gravel roadway with signif icant number,of low speed curves, poor intersections
and no pedestrian or bike facilities. This project would provide a two -lane paved roadway
providing an extension of CSAH 18 to accommodate vehicle, pedestrian, bicycle and school bus
movements while maintaining natural ,features.
PFOJ,ECT NEED,.,
The project need is based on the following factors:
1) CSAH 18 is an important east -west corridor through Carver County, The County is
staging the upgrade., of CSAH:. j8, .from' CSAH 13 (Bavaria Road) over to CSAH 17
(Powers Boulevard:, Po. We : rs, Boulevard provides easy access from CSAH 18 to a TH 212
. _.
interchange.
2) Traffic volumes are expected to increase over the next 20 years. The 2007/2008 daily traffic
Volume ` is approximately 690 vehicles per day. This volume is expected to increase to 2,400
vehicles per day in 20 years without any improvements. An improved.roadway would result.

PREVIOUS WORK
A previous planning study was completed to discuss design principles for CSAH 18 in ilia
project area including vehicles, pedestrians, bikes and horses. The following is a brief summary
of the Chaska Conservancy Ow - retie from Mareh'2007:
Roadway Design
* Design a Scenic Parkway to slow and calm traffic.
Connect 82nd Street to CSA14 18 (Lyman Boulevard).
Include a center median to enhance the natural, look and provide better drainage.
Rural section %rith. vegetative swales adjacent roadkvay.
Roadway alignment and section should not impact significant treed areas.
• Roundabouts to control CSAH 18 at CSAH 13 (Bavaria Road) and McKnight Road
intersections.
Pedestrian and bike trail should be provided on the south side to connect kvith
Chaska Conservancy and Arboretum systems,
• Allow limited direct access to the proposed roadway from existing propellies.
• Prevent traffic from short cutting north on the existing 82nd Street to TH 41.
Pedestrian, Bike and Horse and Cross-Country Trail Design
• Separate each mode, as required
# Maximize the recreational and education experience for trail users
CSAH 18 currently exists cast of TH 41 and' vest of CSAH 13 (Bavaria Road). CSAH 18 does
not exist between TH 41 and CSA111 13, which is slightly less than. two miles in. length.
An. existing gravel roadway proNddes a curvy connection between - these two road% although
the eastern connection is offset one-half mile north of the existing CSAH 18 intersection with
TFI 41 (see Appendix A. for the Project Location Map).
Mr- Lyndon Robjent, PE, County Erigiineer
Carver (' ounly

Page 3 of 10
The existing roadway is unpaved It has sharp curves and uncontrolled intersection, which
makes drivers feel uncornfortable, The roadway does - not provide any pedestrian or bike
facilities. It does not provide a suitable route for school buses, which currently must use TI-I 5.
Much of the proposed roadway is aqjacent the University of Minnesota Landscape Arboretum.
The remaining land use is mainly rural residential.
TRAFFIC ANALYSIS
A traffic analysis wus completed for this project. It is shown in Appendix B and dated July 13,
2010. The - following is a brief summary of the findings:
CSAH 18 Traffic Volumes (Project Area)
# Year 2007/2008 traffic volumes (before New TI.-I 212): 690 vehicles per day
• Year 2009/2010 traffic volumes (after New TH 212): 395 vehicles per day
• 20-Year traffic forecasts with an unimproved roadway: 2,400 vehicles per day
* 20 -Year traffic forecasts with an improved roadway: 8,000 vehicles per day
Actual Impact of TH 212 Opening on TH 5 and CSAH 18:
The opening of TH 212 has resulted in lower traffic volumes on'rH S. The actual. counted
volume reduced Erom 19,100 to 12,200 vehicles per day {wrest. of C.SAI-I *13) and 42,500
to 29,200 vehicles per day (east of Powers Boulevard).
Is The opening of TH 212 has resulted in lower traffic volumes on CSAI-'l 18, The actual
counted volume reduced from 4,000 to 4,000 vehicles per day (west of CSAII 13) to
15,300 to 11,500 vehicles per day (east of CSAH 17).
Forecasted TH 5 Traffic Volumies impacted by CSAI-118 improve ment
Construction of CSAH 18 (betx'veen CSAH 13 to TH 41) is forecast to reduce TH 5 traffic
volumes by 1,400 to 2,800 vehicles per day. The reduction is, at most,. 10 percent of the
daily vehicles. It is anticipated that TH 5 - would be at capacity again shortly after. CSAH 18
opens. with traffic from other routes "backfilling" the void.

Forecasted CSAH 18 Traffic Volumes with T11 5 as our Lanes
• 16whenTH '_5 expands to a four-lane road 20-year traffic forecast volumes are expected
to decrease from 8,000 vehicles per day to 5,700 vehicles per day.
With the 20-year projected traffic volumes of 8,000 vehicles per day, a two-lane roadway would
provide acceptable traffic operations and capacity. If T1`1 5 is expanded from a two-lane to a
four-lane roadway, a two-June facility would still be required for the CSAH 18 connection.
.Based on the forecast traffic volumes, a single-lane roundabout would likely provide acceptable
levels o I' service and capacity at the it of CSAH 18 and McKnight Road.
Originally. three alternatives were developed. The main differences between them were urban
versus rural sections, design speed (40 MPH vs, 45 MPH),, horizontal alignment and typical
sections. The design objectives included providing system. connectivity for vehicles, pedestrians,
bikes and school buses, minimizing environmental impacts, minimizing property impacts and
developing a unique scenic parkway.
Three alteinatives - were developed based on the above desire criteria, Project Management Team
(1 and Policy Advisory Committee (PAC) input and elements discussed at the Chaska
Conservancy Charrette. From group discussions on the original. three alternatives, a fourth
alternative was developed. These Alternatives Alignment Sketches are showm in Appendix C
and the Typical Sections are shown in AppenclN.D.
Alternative I (Red)
Alternative I was developed as a basic urban roadway minimiZing right-of-way requirements
and costs. This alternative provided a standard urban undivided two-lane roadNvay with
shoulders and a 40 MPH design speed. A 10-foot trail is provided on one-side of the roadway.
This type of roadway yields the least amount of'required right-of-way, 90 feet...
Alternative 2 (Orange)
Alternative 2 was developed to provide a combination urban and rural section. This alternative
provided a hybrid urbarL/rural divided two-lane roadway Aith landscaped median. and a 40.M1
design speed. A 10-foot trail is provided on one-side of the roadway. This type of roadway
requires a 120-foot right-of-way.

Carver County
I Page 5 of 10
Alternative 3 (Blue)
.Alternative 3 developed a more typical County design. with. a fitill rural section and higher design
speed. This alternative provided a rural divided t roadAay with a 45 NIP H design speed,
A I 0-foot trail is proposed on one-side of the roadway. This type of roadway requires the most
right-of-way, 140 feet,
Alternative 4 (Green)
This alternative was developed to reduce impacts on residential or Section 6(f) properties while
.maintaining a nattval. rnedian area. 17his alteniative provided mi. urban divided two-lane roadway
with a 40 MPH design speed. A I 0-foot trai is provided on one-side of the roadway, This type
Y.1
of roadway requires a 1 00 -fort right-of-way.
The alternatives were cvaluated during PMT and PAC mectings. The results. were. documented
through the use of an Alternatives Evaluation Matrix (Shown in. Appendix E). Th.e Matrix.
includes estimated project costs, design features shown in the alternative alignments and typical
sections, environmental impacts (broad overview), property impacts and constructability.
Project Mleetings
'1 alternative analysis included four PMT (P ject Management Team) and one PAC (Policy
ro)
Advisory Committee) meetings. The following is a summary of the meetings:
PNIT #1 - January 5, 201
A Project Management Team (PMT) meeting was held on January 5, 2010 at the Minnesota
Landscape Arboretum, The following agencies were in attendance: Carver County,, Cities
ofChanbassen, Chaska and Victoria, Minnesota Landscape Arboretum. and SRF Consulting
Group, Inc.
The following was discussed at the meeting: Project description. and schedule, review layout and
typical sections of the three alternatives, overview of environmental and right-of-way issues.,
and development of a Policy Advisory Committee (PAC). See the Meeting Minutes dated
January 17, 2010 for more details.

No-Build
This alternative does not meet future transportation needs. It does not improve adequate vehicle,
pedestrian or bike connectivity. The existing gravel :road has triany undesirable curves and poor
intersection design,, - which makes it a poor in safely accommodating the expected level of traffic.
Currently, school bus traffic must use TH 5 to access schools. If CSAI-1 18 were completed,
this would become the new bus route,
Alternative I (Red)
This alternative meets rnost needs with minimal impacts, It requires the smallest right-of-way.
least permanent right-of-way acquisition and is marginally more expensive than Alternative
I-lowever,. it does not provide a median and would have 40 feet of continuous width pavement.
This alternative does not lit well into the natural surroundings of the area.
Altetitative 2 (Orange)
This alternative meets most needs of the project. flo-wever, tilis alternative requires the most
per. artent right-of-way, residential building acquisitions and wetland impacts.
.Alternative 3 (Blue)
This alternative meets most of the needs of the project, except it impacts the University of
Minnesota Landscape Arboretum, Section. 6(f) property. This could be considered a fatal flaw,
since other feasible alternatives exist It is also the most expensive,
Alternative 4 (Green)
This alternative meets most of the needs for the prq Ject. It incorporates many of the positive
attributes of the other alternatives, while removing the negative attributes. TWs alternative is
expected to be marginally more expensive than Allerriative 1, but does not require any
acquisition of residential buildings or impact the Section. 6(f) lands.
The preferred alternative is Alternative 4 (Green.). This alternative provides an urban tWo4ane
divided roadway with a separated 10-foot trail and design speed of 40 MPH. This alternative is
marginally less expensive than Alternative 1, and does not impact any residential buildings or
Section 6(f) property. The inverted center median would provide for a more natural look which
is desired for the area.
W Lyndon Robjent, PE.. County Engineer January 12,2011
Carver County Page 1.0} of 10
Alternative 4 was created by addressing positive and neg
,ative elements of the three other
alternatives during discussions with the PMT, PAC and MrL/D0T State Aid Office.
The alignment developed does not require any residential buildings to be taken, as shown in the
three other alternatives, and it also avoids the Section 6(f.) property. This was one of the main
goals when developing Alternative 4. However, in doing so, the alignment does impact other
features., such as wetlands and private property. Another key element was the typical section,
, provides a 20-foot natural median area. 1"he project t earn feels this fits in well with the
natural surroundings of the prqject. The median. provides a linear location for providing storm
water treatment and infiltration. The trail is located on south side of the roadway because it
would provide coimections to future development.
TIMELINE OF NEXT STEPS
A potential timeline was completed for the project process for CSAH 18 between TH 41 and
CS W-1 13. Construction. of this project is planned for 20113, I the preferred alternative for
this segment of CSAH 18 is accepted and funding available, the following would be the next

way acquisition
Meets most needs, but impacts
6(f) property which could be a
fatal flaw, design speed higher
than preferred by local interests,
superelevation of roadway
undesirable
Meets most needs. It avoids
residential impacts and 6(f) property
while fitting well into natural
surroundings, preferred by the PMT.
