MEMORANDUM
TO: Mayor and City Council
FROM: Todd Hoffman, Park & Recreation Director
DATE: November 26, 1997
SUBJ: December 1, 1997 Work Session; Community Trails
I look forward to joining the city council in a work session regarding trails on Monday night.
Walking, running and biking are the top ranking recreational pursuits in the nation. In urban and
suburban settings, trail systems are essential for these demands to be met.
The City's Comprehensive Plan identifies the construction of the Highway 101 north trail as a
Phase I goal (1990 -95). This designation ranks it above the other trail segments in the approved
referendum. Thus, the concern in seeing that the Highway 101 north trail was addressed in
referendum literature. However, as we all recognize, if it were simply a matter of ordering the
project, this trail would have completed years ago.
In 1993, the city council ordered a preliminary feasibility report for the TH 101 trail. A copy is
attached for your review. Due to the cost of the trail and questions over timing, the council never
ordered a complete feasibility study. The project was shelved, but has continued to be a topic of
discussion.
Mayor Mancino is very concerned that our residents are granted appropriate opportunities to
participate in the prioritization, design and construction of the referendum projects. I share in the
Mayor's concern. Review of project plans by the Park & Recreation Commission, attached contracts and correspondence document
Commission and City Council will occur. Th
the intent of this public process. The council's support is essential for these projects to be
successful. I am working hard to keep the lines of communication open.
See you Monday night.

professional services concerning the 1998 Bike Trail Improvements Project.
HRG Project Number 801380P
The CLIENT agrees to employ HRG to perform the following services:
■ Preliminary Surveying: As required to complete plans and specifications. The preliminary
survey will encompass areas that are not sufficiently covered with aerial topography
sufficient to develop a plan and profile for bike trail construction. Areas with sufficient aerial
topography coverage will not be surveyed in an effort to reduce costs on behalf of the
CLIENT.
■ Project Design: Design will include the preparation of plans and specifications for the
construction of six segments of bike trail. Plans will be prepared in stages to allow at least
two reviews by the public prior to final approval of the plans by the City of Chanhassen.

behalf for property required to complete the project. This shall include both permanent and
temporary easements as required for the project construction.
■ Project Management: HRG will assist in the coordination of public information meetings to
facilitate the project design. It is anticipated that these meetings will be held in November of
1997 and January of 1998. Additional project management responsibilities will include
coordination of the surveying, inspection, construction staking, wetland delineation,
permitting, and bidding.
■ Construction Staking: HRG will provide construction staking as required on the project.
Staking will be completed on an as needed basis in areas where construction from the plans
is not feasible as determined by the Engineer. Staking will include the establishment of line
and grade in such areas.

observation personnel will make reasonable efforts to guard CLIENT against defects and deficiencies in the work of the contractor(s), and to help determine
if the provisions of the Contract Documents are being fulfilled. Their day - to-day observation will not, however, cause HRG to be responsible for those
duties and responsibilities which belong to the construction contractor(s), including, but not limited to, full responsibility for the means, methods, techniques,
sequences, and progress of construction, and the safety precautions incidental thereto, and for performing the.construction work in accordance with the
Contract Documents.
13. SEVERABILITY. If any provision of this Agreement is declared invalid, illegal, or incapable of being enforced by any Court of competent jurisdiction, all
of the remaining provisions of this Agreement shall nevertheless continue in full force and effect, and no provision shall be deemed dependent upon any

RE: 1998 BIKE TRAIL IMPROVEMENTS
CITY OF CHANHASSEN
Dear Mr. Hoffman:
CONSIMIC ENGINEERS
Formerly MSA
Consulting Engineers
As requested by the City Council, we have prepared the following written summary of revisions
to our original cost estimate as proposed on September 11, 1997. The estimate to complete the
work increased by approximately $14,700 as a result of concerns identified by staff both at the
interview, and after your preliminary selection was made; and, as a result of the clarification and
addition of several items pertaining to the project scope. Those items are as follows:
Mailing list preparation and coordination — It was requested that HR Green take the
lead in the public relations and notification process as there was concern that City Staff
may not have all of the necessary resources to meet the project's schedule. As such,
we estimated the additional cost of $3,860 for researching property ownership, preparing
mailing lists, and sorting /coordinating by trail segment. These efforts will be undertaken
in order to produce an organized and well- thought -out public involvement process.
Contractor Meetings — In an effort to promote the most competitive bidding available
and to invite the City's most desired Contractors to bid, we anticipate the coordination of
a Pre -bid contractor meeting. In addition, we would anticipate a post -bid meeting with
the low bidder and several on -site Contractor meetings through the duration of
construction to promote a "win -win" relationship between all parties involved in the
project. As such, it was estimated that up to six meetings at approximately $200 would
yield an additional cost of approximately $1,200.
Additional Public Meetings — We had previously anticipated costs of $2,400 for follow
up public meetings on a trail- segment specific basis. As was discussed at the interview
and in subsequent conversations, she need for an additional round of public meetings
was suggested for consideration. As this might result in six additional meetings at up to
$400 each, this item was increased to $4,800.

Construction Inspection — The City anticipates a considerable demand upon its staff
with the amount of construction proposed in 1998. As such, it appears that there may be
an increased reliance on inspection for the trailway projects. We discussed the potential
need for more than one inspector on the job at times when the Contractor is working in
more that one area at any given time. Given these assumptions, we increased the
estimated inspection budget from one full time inspector by a factor of 1.25 to allow a
second inspector on -site during peak construction times. This increased the estimated
inspection budget by $7,200.
The resulting proposed contract amount is estimated at $129,700, or approximately 12'/% over
the original estimate. Please be assured that the engineering portion of the Contract has been
prepared based upon an hourly- not -to- exceed amount based on our best understanding of the
project scope. This scope was fairly well understood at the selection point in this process;
however, subsequent conversations with Staff have clarified areas which we felt were important
to address early in the project rather than approaching the City with extra costs at a later date.
Please be assured that all invoices will detail hourly costs incurred and that Howard R. Green
Company will strive to complete the project as competitively as possible. We stress this point
as our ultimate goal, beyond the success of the 1998 Bike Trail Improvements, is to develop a
long- standing relationship with the City of Chanhassen. I intend to be present at Monday
evening's Council work session to meet your City Council and to address any questions or
concerns they may have regarding our organization in person.
Sincerely,
Howard R. Green Company

I. INTRODUCTION
A preliminary scoping study was completed on February 1, 1993, as requested by
City staff, to examine the proposed construction of a trail along the west side of
Trunk Highway 101 (TH 101) from the south entrance to South Shore Drive to
Pleasant View Road. The trail is proposed to be 8 feet wide and to extend
approximately 9,200 linear feet (1.74 miles). Exhibit 1 in Appendix A illustrates the
project location.
Based upon the results of the study, it was determined that the construction of the
trail segment was possible; however, a number of problem areas were identified.
These problem areas included potential wetland impacts, topographic /grade
problems, conflicts with existing vegetation and private improvements, and
significant right -of -way limitations.
Two neighborhood meetings were held upon the completion of the scoping study to
present the project to the area residents. These neighborhood meetings were held on
March 31, 1993, and April 20, 1993. Based upon input received at these meetings, it
appeared that there was general support for the project; however, some strong
opposition was expressed by residents whose property directly abuts TH 101.
Residents supporting the project stated that existing curves and hills in the roadway
alignment along with traffic speeds and volumes currently limit or prohibit safe use
of TH 101 for pedestrians and cyclists. Another supporting reason given was that the
trail would provide an important pedestrian /bicycle access to downtown Chanhassen
for residents living along the TH 101 corridor.
Property owners along TH 101 expressed concern that the proposed trail would
significantly impact their properties and would reduce property values, require
removal of mature trees, and create even greater safety problems with private
driveway accesses to TH 101. They also expressed the need for landscaping buffers,
fences or other improvements to limit impacts to their properties if the trail
construction were to proceed.
On May 24, 1993, the City Council ordered the preparation of a feasibility study for
the TH 101 Trail Project based upon the results of the neighborhood meetings and
recommendations from staff. This feasibility study further studies the concerns
identified by the scoping study and the neighborhood residents, and presents
possible design solutions, estimated costs and preliminary project plans.

II. PROPOSED IMPROVEMENTS
A. GENERAL DESIGN CONSIDERATIONS
The primary design consideration for the TH 101 Trail is that it is a safe route
for its users with respect to the vehicular traffic on adjacent TH 101 and to
other trail users. The primary means of providing safety between vehicles and
trail users is by physical separation. Minnesota Department of Transportation
(Mn /DOT) bikeway design guidelines call for a minimum separation distance
of 20 feet between pathway and edge of road when there is no curb and 4 feet
when the roadway has a curb. When these distances cannot be provided,
safety measures such as guardrails may be required to reduce safety concerns
associated with the trail location.
Because of the existing right -of -way constraints, the required minimum
separation distance is achievable along only approximately 33 percent of the
project area. Discussions with Mn /DOT personnel indicated that flexibility in
separation distance criteria may be allowed; however, each condition will be
reviewed independently based on site conditions. Based on this input, the trail
was designed within existing right -of -way with the expectation that Mn /DOT
will approve the alignment if measures are included to protect areas where
separation distances are small. Where the maximum feasible separation
distance fell below 10 feet, additional measures including the installation of
guardrails and /or bituminous curb along TH 101 were incorporated to achieve
the desired level of safety. These areas are discussed later in this section on a
case by case basis.
Safety between trail users is achieved by means similar to those used for
vehicular roads. Mn /DOT generally requires a minimum width of 8 feet for
two -way multi -use trails. Consideration is also given to transverse and
longitudinal grades and to proper visibility for travelling over hills, around
curves, and for stopping safely. In most cases, meeting these requirements
was not a difficulty since the trail alignment generally follows the existing
roadway which meets these criteria.
Secondary considerations were given to maintaining existing trees, shrubs,
utility structures, and existing private improvements where possible. In most
cases these conflicts were minimized by shifting the proposed trail alignment
closer to TH 101 and including bituminous curb and /or guardrails in the
design.
The proposed trail would be designed to meet existing grades at the inter-
sections of local streets and private driveways to minimize removal of existing
bituminous pavement. Existing unpaved driveways would be paved where
the proposed trail crosses, again meeting existing grades.
.:1: -4 2
The proposed trail would be constructed with the City standard pavement
section of 3 inches of bituminous wear course and 6 inches of aggregate base
course. Restoration work would include sodding along the edge of the trail
and in residential lawn areas, with seeding of the remaining areas.
Exhibits 2 through 6 in Appendix A illustrate preliminary plans and cross -
sections for the proposed trail construction.
A majority of the storm water runoff in the project area is currently collected
by ditches along TH 101 which discharge the runoff to the various wetlands
along the roadway. In general, the proposed trail construction allows the
existing ditch alignment and flow directions to be maintained as much as
possible. Several culverts will, however, need to be relocated or replaced to
allow the trail construction.
Where bituminous curb is proposed, existing ditches and culverts will be
eliminated and runoff will flow along the curb line of TH 101. Storm water
flowing along proposed curb will be routed back into the ditch at the ends of
curb sections.
The existing ditch alignment and grades should be evaluated further as a part
of the final trail design to determine any additional storm drainage
improvements.
C. LTITLTITES
Numerous above ground and underground utilities are present in the project
area. Natural gas, telephone, and cable television lines run parallel to TH 101
between the edge of pavement and the westerly right -of -way line. Several
control boxes for cable TV and telephone must be relocated for the proposed
trail construction. Numerous power poles along the proposed trail alignment
also must be relocated.
D. SPECIFIC AREAS OF CONCERN
The proposed trail alignment includes a number of specific areas of concern as
detailed below. The locations of these areas are identified by stationing
provided on the preliminary trail plans included in Appendix A.
1. Station 10 +70 to Station 12 +40: Existing shrubs will need to be removed
back to the right -of -way line. These shrubs currently extend 0 -10 feet
into the right -of -way.
.isms 3
2. Station 13 +50 to Station 26 +50: This area includes a steep slope 250 feet
long protected by a guardrail and thirteen residential properties with
direct access to TH 101. Many of these properties have fences and
retaining walls within the right -of -way. Numerous utility poles and
boxes are located throughout this area.
The most feasible alignment in this area is offset approximately 5 feet
from TH 101. The existing guardrail will provide a safety barrier for a
250 foot portion of this area, while the addition of bituminous curb to
TH 101 is proposed for the remaining areas. In -addition, approximately
300 linear feet of 6 to 8 feet high retaining wall will be required along
existing right -of -way adjacent to the steep slope.
We recommend that the existing guardrail be extended approximately 50
feet to the south requiring the driveway access for #7510 Chanhassen
Road to be relocated from TH 101 to Hill Street. The trail design would
include the removal of the planter at Hill Street and TH 101 and the
restoration of the ditch in this area. Permanent barricades or
landscaping would be required to prevent access to Hill Street from
TH 101.
3. Station 43 +25 to Station 50 +00: Only 7 feet of right -of -way is available
in this area adjacent to the right -turn lane currently being constructed
north of Cheyenne Drive. The right -of -way along this section of the trail
also includes approximately 125 feet of wetland area and 150 feet of
wooded land.
The trail is proposed to be constructed along the right -of -way line
throughout this section. The installation of bituminous curb and 300 feet
of guardrail north of Cheyenne Drive is proposed due to the limited
separation distance between the trail and TH 101 in this area.
In order to minimize wetland impacts north of Cheyenne Drive, the
preliminary trail design includes a short retaining wall in this area. The
wall will reduce the area required for embankment fill and consequently
reduce encroachment into the wetland.
A temporary construction easement will be required in the area of the
wetland and several trees will be required to be removed in the last
150 feet of this trail section.
4. Station 52 +75 to Station 55 +50: Only 7 feet of right -of -way is available
in this area at the right -turn lane north of Sandy Hook Drive. In
addition, an existing modular block retaining wall is located
approximately 3 feet inside of the right -of -way line in this area. To
avoid the removal /relocation of the retaining wall and the removal of
large trees which provide screening for the resident at 20 Sandy Hook
013W4 4
Road, it is proposed that a guardrail be installed along TH 101 and the
trail be limited to a width of 4 to 5 feet at this location.
5. Station 55 +50 to Station 58 +50: Purgatory Creek is located in this area,
with an inlet control structure for the Creek located approximately
30 feet west of the right -of -way line. Construction difficulties associated
with the Creek should be limited; however, relatively steep trail grades
(+ 8 percent) and numerous tree removals will be required in this area.
6. Station 68 +50 to Station 72 +00: The region between the edge of TH 101
and the right -of -way line is wetland in this area. Approximately 2,400
square feet of this existing wetland will be required to be filled for the
trail construction. In order to minimize wetland impacts, the trail
alignment was shifted to run within 5 feet of TH 101 and 300 feet of
retaining wall is proposed to be constructed along the west side of the
trail.
7. Station 86 +25 to Station 87 +75: Only 7 feet of right -of -way is available
adjacent to the right -turn lane north of Fox Hollow Drive. The proposed
trail alignment would include 150 feet of guardrail and bituminous curb
from Fox Hollow Drive north until safe separation is achievable between
the trail and TH 101. The trail construction may require slight
modifications to the existing monument sign; however, no impacts on
the storm water detention pond are expected.
8. Station 63 +00 to Station 69 +00: Temporary construction easements will
be required in this area for tree removal, retaining wall construction, and
grading. Approximately seven properties are abutting the right -of -way
in this area.
9. Station 75 +50 to Station 77 +50: Temporary construction easements will
be required in this area for tree removal, grading and culvert
installation. One private property owner abuts the right -of -way in this
area.

III. PERMITS
The construction of the TH 101 Trail Project would require the acquisition of the
following permits:
A. Mn /DOT Limited Use Permit
A Mn /DOT limited use permit would be required for the trail since it is
proposed to be constructed within Mn /DOT owned right -of -way along
TH 101. The limited use permit would grant the City the right to construct
and maintain the trail.
The limited use permit will require Mn /DOT review and approval of the plans
for the trail construction. If this project proceeds to final design, it will be
important to involve Mn /DOT in the design process to minimize difficulties in
obtaining this permit.
B. Army Corps of Engineers Permit
A Corps of Engineers Nationwide Permit will be required for work in the
existing wetlands. The anticipated wetland impact is less than 0.1 acre over
the entire trail alignment. Based on the limited wetland impacts, it is not
expected that any difficulties will be encountered in obtaining this permit. The
Corps of Engineers reserves the right to require mitigation of lost wetlands;
however, it is likely that mitigation would be waived for this project.
C. City of Chanhassen Wetland Alteration Permit
A City of Chanhassen Wetland Alteration Permit will be required for work in
the existing wetlands. Similar to the Army Corps of Engineers permit, it is not
anticipated that difficulties will be encountered in obtaining this permit due to
the limited wetland impacts.
D. Riley Purgatory Bluff Creek Watershed District Permit
A permit from the Riley Purgatory Bluff Creek Watershed District will be
required for the construction of the trail. The Watershed District will review
the project with regard to temporary erosion control measures and wetland
impacts. It is not anticipated that any difficulties would be encountered in
obtaining this permit.

V. ESTIMATED COSTS
The estimated project costs for TH 101 Trail Project are shown below. The costs
assume that the trail would be constructed in accordance with the preliminary plans
shown in Exhibits 2 through 6. Modifications as a part of the final trail design could
result in an increase or decrease in the project costs.
Please note that a 40 percent allowance has been included in determining the total
project cost to allow for indirect items such as engineering, administration, legal and
contingency items. Costs have not been included for any land or easement
acquisition required for the trail construction.

The estimated construction . cost includes a $25,000 allowance for landscaping
improvements. It is anticipated that these landscaping improvements would include
trees, shrubs and other improvements to enhance the aesthetics of the project area. A
detailed cost estimate for these improvements cannot be determined at this time since
the scope of the landscaping improvements will be somewhat dependent upon
discussions/ negotiations with property owners along the trail alignment.
VI. SUMMARY AND RECOMMENDATIONS
The TH 101 Trail would be a valuable addition to the City's current trail system
serving as an important pedestrian /bicycle access to downtown Chanhassen for
residents living along TH 101. Based upon the results of this feasibility study, it
appears that the trail construction is possible; however, it would be relatively difficult
and expensive considering the numerous constraints of the project area.
The benefits of the proposed trail improvements should be considered along with the
construction difficulties and costs and the opposition of residents living along TH 101
to determine whether the project should proceed to final design. If the project does
proceed, it is recommended that residents along TH 101 be allowed to play an active
part in the design of the trail to help address some of their concerns.
The involvement of Mn /DOT throughout the final design process would also be
important to the success of the project. Where Mn /DOT concerns conflict with the
concerns of the City and the residents along TH 101, compromises must be made to
achieve a design acceptable to all parties. While it appears that Mn /DOT would
allow the construction of the trail, it is likely that numerous meetings and
negotiations would be required to determine the final design for the trail
construction. Some of the Mn /DOT final design requirements may have an impact
on the project costs.
The decision to proceed with the final design and construction of the TH 101 Trail
Project should also consider any potential improvements to TH 101 in the near
future. It may be desirable to delay the decision to proceed with the project until a
more definitive decision is made by Mn /DOT regarding the future of TH 101 and
possible upgrading and reconstruction of the roadway.
