on Improvements, NE Area Drainage Study
VOTE REQUIRED:
INTRODUCTION
3/5
Staff is requesting council authorization to retain WSB & Associates to prepare a feasibility
report for the proposed NE Area Drainage system.
BACKGROUND
The City Council authorized preparation of the NE 35E Area Drainage Study in November of 2012.
The purpose of the study was to evaluate options to address drainage for a 700 acre area lying NE of
the 35E interchange. The majority of this area drains to County Ditch 55, under 35E and ultimately
to Clearwater Creek. Land within this area is poorly drained with clay soils that have minimal
infiltration capacity. Additionally, the tile line (Ditch 55) that conveys water from this area was
constructed in the early 1900's for agricultural purposes. The size of the tile ranges from 10 to 15
inches and does not have the capacity to carry new runoff from developing properties.
The initial conceptual plan submitted to the Rice Creek Watershed District (RCWD) proposed the
construction of a new storm sewer line running south to Clearwater Creek. However, after further
review, a rd alternative was developed that would 1) address a surface water management over a
larger drainage area, and 2) avoid issues related to possible increased flow volumes to Clearwater
Creek. The proposal would provide a new outlet directly to Peltier Lake and provide an improved
drainage outlet for nearly 1,400 acres while creating a high value greenway system, as proposed in
the Comprehensive Plan, and improving water quality entering Peltier Lake.
In July of 2014 the City Council authorized the expanded scope of the drainage study to incorporate
the entire 1,400 acre drainage area and to prepare a Comprehensive Stormwater Management Plan
for review and approval of the RCWD. City staff submitted the draft NE Area Comprehensive
Surface Water Management Plan (CSMP) to the RCWD in June of 2015 for review and
comment.
A technical memorandum from the RCWD was received on July 9, 2015. The RCWD has
requested additional information as part of the approval process. These requests have been
incorporated into a proposal from WSB & Associates to complete a feasibility report for the
project. The purpose of the report is to:
L
• Confirm modeling results and parameters.
• Examine design alternatives and develop a preferred alternative.
• Prepare preliminary design and cost estimates.
• Develop and recommend proposed pipe alignments.
• Identify effected property owners and stakeholders.
• Identify all necessary permits.
• Identify potential funding options.
WSB & Associates have proposed to complete the report for a not to exceed amount of $69,076.
Funding for the study will be provided by the City's Surface Water Management Fund. This
fund was established in 1992 to pay for stormwater management planning and trunk
improvements. Fees are collected from property at the time of development.

Re: Proposal and Scope of Work to Finalize Stormwater Plan and Complete Feasibility Study
for Storm Sewer Outlet for Northeast Area of Lino Lakes
City of Lino Lakes, MN
Dear Mr. Grochala:
The City of Lino Lakes is requesting assistance with the development of a feasibility report
associated with providing a new storm sewer outlet for a 1,400 acre area in northeast Lino Lakes.
This proposal and scope of work is prepared in response to this request.
As part of this effort, WSB would perform the following tasks:
1. Finalize/Memorialize Design Parameters for Project
Based on discussions with City staff, RCWD staff, their consultants and DNR, due to
downstream impact concerns, the stormwater plan and model for the area will need to be
updated to reflect the feasibility level design developed. As part of this effort, we will
update and memorialize the storm water plan for the area, prepare and follow up on a no -
rise certification submittal to DNR, and prepare other necessary submittals to the RCWD.
Although there are no guarantees that approvals will be granted for the project until the
final design is completed and permits are issues, these submittals are needed at this stage
to increasingly verify to a reasonable extent the project is feasible. Upon completion of
this task, a blueprint for the amount of live storage, dead pool storage, water reuse, or
infiltration to be provided when the area is fully developed will be available, along with
an implementation plan.
Schedule and Cost
It is anticipated this work will take six weeks to develop the reports and submittals
outlined above, and additional time to receive the responses from those agencies. Some
of this work can and should be completed concurrently with other tasks. This work can
be completed at an estimated cost of $16,772.

2. Complete Feasibility Level Design Work
As part of this task, background information for the project area that is needed for this
feasibility report will be gathered, reviewed, and analyzed along with other information
gathered during previous studies. This effort will be focused on development of an outlet
design for the trunk system that reflects the most cost effective feasible way for the outlet
to be constructed. As part of this effort, an updated evaluation of the cost to provide
more storm water storage and a smaller capacity pipe versus less storm water storage and
larger capacity pipe will be undertaken along with the impact of these options on Peltier
Lake.
This analysis will be focused on only the outlet alternative that was selected as part of the
previous sequencing analysis effort. Although, the feasibility report may discuss other
options in a more general way, it is anticipated that only one alignment and design option
will be formally evaluated as part of this work. Upon completion of this task, the
recommended conveyance type (ie. open channel, or pipe), alignment, outlet pipe size,
slope, and capacity, inlet locations and other appropriate design features will be
developed for the trunk system that will serve the project area.
A project memorandum will be provided at the completion of this task summarizing the
results and justifying the design recommendation provided.
Schedule and Cost
It is anticipated that this work will take four weeks to complete at a cost of $13,352.
Some of this work can be completed concurrently with the work outlined in Task 1.
3. Develop Preliminary Plan and Cost Estimate for Outlet
A preliminary plan and profile for the outlet will be developed as part of this task to the
extent necessary to verify the feasibility of the system, allow for quantity take offs to be
undertaken, and develop an estimate of cost to complete the project.
Schedule and Cost
It is anticipated this work can be completed in three weeks, with some of it undertaken
concurrently with the work completed on the previous tasks. The cost for this work is
estimated at $5,864.
4. Meet with Stakeholders, Review Preliminary Plan and Cost Estimate
As part of this task, it is anticipated that up to three meetings will be held to review the
preliminary plan with stakeholders to obtain input into the design and cost estimate.
Because the project will need to be acceptable to developers and property owners in the
area, this communication effort will be extremely important and it's anticipated some
changes to the plan may be necessary to address their concerns.
Schedule and Cost
It is estimated that this task will take three weeks to complete at a cost of $5,572.

5. Update Preliminary Plan / Cost Estimate
Information gathered during Task 4 will be incorporated into the design for the outlet and
an updated preliminary plan and cost estimate will be developed.
Schedule and Cost
It is anticipated this work can be completed in three weeks at a cost of $2,580.
6. Update RCWD Hydrologic Model for Improvements
The RCWD has indicated that when the preliminary design is complete, the RCWD's
Hydrologic model must be updated to reflect this outlet project being installed. In order
to verify the feasibility of the project, development and submittal of this information has
been incorporated into this work plan. Modifications to the model following this
submittal would be an extra to this scope of work.
Schedule and Cost
It is anticipated this work can be completed in three weeks at a cost of $12,312.
7. Prepare Feasibility Report
As part of this task, the feasibility report will be prepared that outlines need for the
project, options considered, description of recommended design option and cost, a
discussion of financing options, and other standard information that is required for
inclusion in a feasibility report.
Schedule and Cost
It is anticipated that this work can be completed in three weeks at a cost of $7,604.
8. Review Plan and Feasibility Report with City Staff and Stakeholders
This task includes reviewing the draft feasibility report with stakeholders and, based on
input received, make appropriate additions, deletions, or corrections. Please note that
only general approaches to funding and financing this project will be discussed within
this report, and no defined assessment role is anticipated to be prepared at this time.
Schedule and cost
It is anticipated this work will be completed within three weeks at an estimated cost of
$2,716.
9. Submit and Review Results of Feasibility Study with City Council
It is anticipated this report will be submitted and reviewed with the City Council at a
Council meeting or workshop. Preparation for and attendance at two meetings are
anticipated to facilitate this task.
Schedule and Cost
It is anticipated this work can be completed in three weeks at a cost of $3,304.
