RE: Proposal for the Lake Marion Shoreline Natural Resource Management Plan –
Casperson Park and Juno Trail
Dear Mr. Cafferty:
As requested, Wenck Associates, Inc. (Wenck) submits this proposal to assist the City of
Lakeville (City) in developing the Lake Marion Shoreline Natural Resources Management Plan.
This plan will cover the areas along the Lake Marion shoreline in Casperson Park and along
Juno Trail. Casperson Park is City park located along the shoreline of Lake Marion that
includes a variety of outdoor recreation facilities for park users including a boat launch, picnic
areas, playground, and lake access points. Juno Trail is a multi-use paved trail and an
important recreational resource to the residents of Lakeville and greater Dakota County. The
trail is approximately 1.25 miles from the boat launch in Casperson Park to the Juno Trailhead
located at 205th Street. Approximately 0.75 miles of the trail is located on City property within
Casperson Park, West Lake Marion Park, and the Juno Trail head. Juno Trail is connected to
other trails in Lakeville and is part of the regional trail system within Dakota County. The trail
receives significant use from people enjoying the aesthetic setting as the trail travels along
the west and south side of Lake Marion.
The focus will be to develop a natural resource
management plan for the portions of the Lake
Marion shoreline that are located on City
controlled property in Casperson Park and along
Juno Trail. Wenck will partner with the City to
develop a natural resources management plan for
these areas of Lake Marion shoreline identifying
features to manage and improve habitat
conditions along the trail corridor, enhance the
aesthetic experience for trail users, address
shoreline erosion concerns, and guide public
access and usage of park resources along the
trail.
The plan will be used to guide City management activities for natural resources associated
with Lake Marion shoreline in Casperson Park and along Juno Trail over a multi-year period.
The plan will be used to help secure potential natural resource improvement funding and
grants. Based on City input, we identified three tasks to be completed to develop the natural

resources management plan: 1) data collection and field assessment; 2) development of draft
management plan; and 3) project team meeting and final plan development. A description of
the scope and budget for each task is provided.
Task 1 – Data Gathering and Field Assessment
Approximately 0.75 miles of Juno Trail that is located on City property between the Casperson
Park boat launch and the Juno Trail head at 205th Street. Trail use include pedestrians, pet
owners, bicyclists, roller bladers, fishermen, bird watchers, and kayakers that access and
utilize the trail at various locations. The trail is adjacent to Lake Marion, ranging from five to
15 feet from the shoreline. Between the trail and the shoreline, natural resources are a mix of
wetland and upland vegetation communities
including trees, shrubs, grasses, and flowers.
Access to the lake shoreline is influenced by the
existing vegetation community. Grasses, flowers,
and native plants are trampled and impacted by
trail users accessing the lake shoreline. In other
places dense tree and shrub cover prevents
shoreline access. Areas of invasive or low-quality
plant species, in terms of habitat value or ability
to stabilize the shoreline exists. Uncontrolled
access to the lake shoreline is exacerbating
degradation and erosion.
One goal of the natural resource management
plan is to quantify the existing natural resources
along Lake Marion shoreline and the trail to
determine areas where management activities are
beneficial. Wenck will conduct a field assessment of the existing habitat conditions for the
0.75 miles of trail located on City property. The assessment will include a two-person field
survey team for one field day to collect the data needed for plan development. The field
assessment will:
• Document vegetation communities, identify species including invasive, and assess
quality of the current habitat conditions along the trail and adjacent lake shoreline;
• Identify areas where invasive or undesirable species require management;
• Identify and assess terrestrial and aquatic habitat along the trail and within five feet of
the lake shoreline;
• Identify areas of shoreline erosion or where habitat has been negatively impacted; and
• Determine potential access points between the trail and lake shoreline.
Wenck will review where trail users are currently accessing the lake in the context of how
access is potentially impacting habitat conditions or contributing to shoreline erosion.
Parameters quantifying the level of shoreline impacts will be collected during the field
assessment including bank height, slope, and length of eroded areas. Photo documentation of
all relevant habitat, vegetation, access points, and shoreline conditions will be collected during
the field assessment. The goal of the assessment is to develop proposed management
activities that complement the existing designated access points and management activities
that have been completed by the City.
Wenck will coordinate the field assessment with the City staff from the Environmental
Resources and Parks departments. The on-site meeting with City staff at the start of the field
Area of Lake Marion shoreline where the
vegetation and habitat conditions have been
impacted by trail users accessing the lake.

assessment will be the “kick-off” meeting for the project. Prior to the field assessment Wenck
will contact the City to acquire existing conditions information related to the trail and park
resources. Information provided by the City includes existing topo data, edge of pavement for
trail, known utilities, and park amenities.
All field data collected by Wenck will be provided to the City as GIS shapefiles, CAD files,
and/or spreadsheet format as needed. The total estimated cost for Task 1 Data Gathering
and Field Assessment is $4,100
Task 2 – Development of Draft Natural Resources Management Plan
Wenck will utilize the data collected under Task 1
to develop the draft natural resource
management plan. The plan will include
recommendations for vegetation management,
habitat enhancement, invasive species or low-
quality vegetation removal and control, shoreline
stabilization techniques, and integration of trail
use with designated access points to the lake
shore and other park amenities. The City
conducted past vegetation management and
shoreline improvement projects along sections of
the trail that will be included in the management
plan. Wenck will identify these areas within the
plan and ensure recommended management activities fit with the approach and aesthetic look
of previous projects completed by the City. The shoreline information collected during the
Task 1 assessment will be used to propose improvement projects. Based on the initial field
meeting between City staff and Wenck to review Juno Trail, the shoreline areas to be
addressed are not as steep as the fishing access that was constructed along Juno Trail in Fall
2017. Wenck will explore shoreline stabilization techniques including natural shoreline
vegetation enhancement, coir log toe, riprap toe, and/or riprap armoring. Wenck will also
review previous management activities completed by the City to direct or exclude access from
the trail to the shoreline and other park amenities including the use of split rail fences and
hard scape pathway such as gravel or flagstone. This information will be incorporated into the
plan as needed to meet City goals for natural resource management along Juno Trail.
The management plan will be developed as a
graphical plan set. The plan set will include
narrative regarding the methods and findings of
the field assessment to document existing
conditions as well as discussion of proposed
management activities. Folded into the plan
narrative will be photos documenting existing
conditions, figures identifying areas for
management activities, and conceptual renderings
of proposed habitat improvement and shoreline
stabilization features. The plan will also include a
phased schedule for planned management
activities over a multi-year period. Potential
reoccurring maintenance activities will also be
identified. A cost estimate for the proposed
management and shoreline stabilization activities

will also be included. The draft natural resources management plan will the be provided to the
City for review and comment.
The estimated cost for the Task 2 Development of Trail Natural Resources Management
Plan is $9,500.
Task 3 – Project Meeting and Final Management Plan
Wenck will submit the draft plan to the City for review and then schedule a project team
meeting to review the plan approximately two weeks after the plan is submitted to ensure
adequate time for the City to review and provide comments. After reviewing the initial draft
management plan, Wenck will address one round of comments. Incorporation of comments
will be used to develop the final management plan. Wenck will update the proposed
management activities, schedule, and cost estimates as directed by the comments to ensure
the City’s goals for the overall management plan are achieved. Wenck will provide two hard
copies of the final management plan as well as electronic copies of the project documents
including field photos, GIS information, word documents, and final PDF document.
The total estimated cost for the Task 3 Project Meeting and Final Management Plan is
$4,600.
The plan will not include detailed engineering plan sets or specifications suitable for bidding or
construction. When the City is ready to implement a specific management activity or set of
activities, Wenck will develop a scope and budget to assist the City with necessary tasks as
requested. Additional future project tasks that may be needed to implement natural resource
management actions could include permitting, development of engineering plan set and
specification packages, or providing quote/bidding assistance to the City.
Project Schedule and Budget
Based on discussions with the City, Wenck is assumes the project would be authorized to start
by September 17th and work would need to begin immediately. Wenck would target
conducting the field assessment before September 30th to ensure that the analysis of habitat
and natural resource conditions along the trail is completed during the summer growing
season. The actual date of the field assessment will be coordinated with the City to ensure
appropriate City staff (from environmental resources, parks, etc.) are available for this initial
meeting. Wenck would begin development of the draft management plan after the field
assessment has been completed. Wenck would have the initial draft management plan
submitted to the City for review by October 31st. Allowing, two weeks for City review of the
draft management plan, the project team meeting with City staff to review comments on the
draft plan would be mid-November. After Wenck received comments from the City on the draft
management plan, the final plan would be provided to the City by December 15th. This will
allow the plan to be used to implement management activities along Juno Trail in 2019.
Wenck proposes to complete the tasks outlined above following the terms and conditions of
the current Master Services Agreement. The work would be completed under our time and
materials rates for a not to exceed amount of $18,400 as outlined in the table below. We
would not exceed this budget amount without prior authorization from the City. If additional
services are requested or out-of-scope tasks are identified, Wenck would provide the City with
a scope and budget for authorization before proceeding.
