Agenda Number:
DATE: November 25, 1998 for the City Council Meeting of November 30, 1998
TO: Dwight D. Johnson, City Manager
FROM: Fred G. Moore, Director of Public Works
SUBJECT: REVIEW OF PLYMOUTH WATER RESOURCES MANAGEMENT
PLAN
ACTION REQUESTED: After a review of the Water Resources Management Plan
gives staff direction on any changes or additional information requested by the City
Council.
BACKGROUND: In August 1995, the City began developing the Water Resources
Management Plan. The two main purposes of the plan are to update the 1980 Storm
Drainage Plan and to address water quality issues. As the plan evolved, the focus shifted
more towards City -wide water quality management. The City's plan must conform to
the requirements of the four water management organizations (WMO) and be in
conformance with regional plans of the Metropolitan Council.
The plan was prepared by the City's consultant, Short, Elliott, Hendrickson, Inc. (SEH)
with direction and input from City staff and the Water Quality Committee. Also, at the
very beginning of the plan, public meetings were held to which lake associations and
citizens were invited to provide input into the plan.
In February 1998, the City Council held a study meeting on the goals and policies for the
plan. The goals and policies provide the background for the development of the entire
plan. After review, the City Council approved the goals and policies with direction on
some modification.
The completed plan was presented to the Environmental Quality Committee (EQC) for
their review and recommendation. They made a recommendation on the plan to the
Planning Commission for approval with a few minor modifications. These modifications
have been incorporated in the Planning Commission recommendation. The Planning
Commission, after holding a public hearing on September 22, 1998, is recommending the
plan to the City Council for approval. Their recommendation includes the items added

by the EQC and two additional modifications. Attached are the minutes from the
November 10, 1998 Planning Commission meeting on their discussion and motions in
recommending approval of the plan by the City Council. Also attached are the seven
changes recommended to the plan. Staff concurs with these changes.
I am also attaching a copy of a memorandum dated November 5, which I prepared to the
Planning Commission addressing their questions from the September 22 public hearing.
Attached to that memorandum is the staff report which the Planning Commission
received for the September 22, 1998 public hearing.
The Planning Commission, City Councilmembers and Councilmembers elect (then
Council candidates) received a copy of the plan in mid- September. For that reason an
additional copy is not attached to this report.
One of the questions answered for the Planning Commission was on the cost for the
estimated implementation of the plan. It is estimated that the cost to implement this plan
over a ten year period is $7,799,000. Of this amount, we have identified that
3,654,000 are new expenditures that are not currently within the City's budget.
Attached is a summary by general category showing the new or additional expenditures
for the plan implementation. The report to the Planning Commission (November 5,
1998) gives a summary review of possible financing methods for the plan. Also attached
is the summary page from the plan indicating advantages and disadvantages of different
funding alternatives. More details on these funding alternatives are indicated on Pages
116 through 123 of the plan.
The City's consultant will make a brief presentation to the City Council on the plan at the
study meeting. Shane Missaghi, the City's Water Resources Engineer and I will also be
in attendance to address additional questions which the City Council may have.
The review and approval of our Water Resources Plan cannot move forward until the
City Council gives preliminary approval to the plan and authorizes its submittal to the
organizations. We estimate that it will require four to six months before we receive their
review comments, propose necessary changes or answer questions and present the final
plan to the City Council for adoption.
Although this is a proposed plan for a ten year period, both the Planning Commission
and City Council will need to review it within the next year as part of our
Comprehensive Plan Update. Also, beginning in 2002, the watersheds will begin to
update their plans which may mean additional review and updates to our local plan.

Staff believes that this is a very comprehensive water resources plan which will improve
water quality within the existing urbanized area of Plymouth and provide standards which
will reduce the likelihood of reduction in existing water quality in the non - urbanized
portions of the City.

Director Fred Moore gave an overview of the November 5, 1998 staff report. Director
Moore stated that $750,000 is spent on street related issues on an annual basis. He
presented new /additional expenditures to the implementation plan: Studies - $578,000;
DNR/Plant Management $150,000; Drainage /Pond Inspection Program - $196,000;
Alternative Landscape Monitoring - $60,000; Document Existing Treatment Capacity -
200,000; Pond Maintenance Access $200,000. Subtotal - $1,384,000 Construction -
2,270,000.
Commissioner Thompson asked if it is legally possible to retroactively require buffers
along shorelands. Director Hurlburt responded that she didn't think there is anything in
the plan that will address that. She said that staff determined through the process of
developing the wetland ordinance that you can't apply buffers retroactively. She stated
that she didn't know of any community that has tried to require retro buffering. Director
Moore said that it may be possible to establish some financial incentives for people to do
this.
Commissioner Berkowitz asked if the City has thought about providing buffer
monuments and technical assistance for voluntary buffering. Director Hurlburt replied
that staff is already providing technical assistance. Planning Supervisor Senness stated
that the materials for buffering should be professionally applied in order to work which
would raise the cost to homeowners. Director Hurlburt noted that one thing the staff uses
to encourage buffers is the problem with geese complaints. Water Resource Engineer
Missaghi commented that he also works with various homeowners associations.
Commissioner Stein asked if any have actually implemented restoration of a buffer.
Water Resource Engineer Missaghi replied affirmatively.
Commissioner Ribbe stated his concern for implementing the plan until funding sources
have been determined. He said that there may be a need for a commitment from the
taxpayers in order to make this realistic to achieve the goals of the plan. Director Moore
commented that there is a section in the plan that gives several financing sources, which
will have to be addressed after the plan is adopted. He said that when the plan is adopted,
staff will then know how aggressive it should be handled and can address the finance
issues over 10 years. Commissioner Ribbe noted that 40 percent of the projected cost is
for expert labor. Director Moore commented that a lot of it is studies and staff labor, but
until a detailed study is done on a watershed by watershed district basis, you don't know
how much needs to be done. He said that this is an on -going plan that will continue even
after 10 years. He added that the City is required by state law to address water quality
and water quantity.

Commissioner Stein asked if the plan would come back to the Commission periodically
for review. Director Moore replied that the plan would come back formally as part of the
Comprehensive Plan. He said that the plan will need to be updated as watershed plans
are updated.
MOTION by Commissioner Thompson, seconded by Commissioner Stoebner
recommending approval of a Comprehensive Plan Amendment for the City of Plymouth
for the Water Resources Management Plan.
MOTION to Amend by Commissioner Berkowitz, seconded by Commission Thompson
to remove the recommendation for the ban on city -wide phosphorus fertilizers.
Commissioner Berkowitz stated that the didn't think an overall ban is the way to go. He
said that banning the sale of phosphorus fertilizers in Plymouth would have a better
affect.
Commissioner Ribbe stated people can still drive to other cities for sources of fertilizer.
He said that the symbolism of a ban sends a forceful message that people should quit
using something that isn't necessary.
Commissioner Stein commented that the ban on the sale would at least start the learning
process.
Commissioner Stoebner suggested that the language is broad enough that it could mean
the use or sale, and that the City Council should grapple with that issue. He said as
worded it would be appropriate.
Commissioner Thompson suggested that the wording state ban sale or use of fertilizer.
Commissioner Berkowitz commented that with the items underway through the
legislature or the Metropolitan Council, maybe the City should just focus on educational
issues and see what happens.
Roll Call Vote on MOTION to Amend. 1 Aye. MOTION failed on a 1 -5 Vote.
Commissioners Ribbe, Stein, Thompson, Stoebner and Chairman Stulberg voted Nay.)
MOTION to Amend by Commissioner Thompson, seconded by Commissioner
Berkowitz to change the wording to the "ban on the sale or use of phosphorous base
fertilizers."
Commissioner Stoebner commented that the City Attorney said there would be a problem
with a ban on the sale. Commissioner Thompson said it would be the same problem as
DRAFT
Planning Commission Minutes
November 10, 1998

banning the use, but it would have more of an affect on retailers. Commissioner Stoebner
said that anything that would have a chilling affect on the sale would be good.
Commissioner Berkowitz stated he would support the amendment. Roll Call Vote. 5
Ayes. MOTION approved on a 5 -1 Vote. (Chairman Stulberg voted Nay.)
MOTION to Amend by Commissioner Thompson to add further consideration of the
feasibility of the retroactive requirement of buffers on lake shore properties. MOTION
to Amend died for a lack of a second.
MOTION to Amend by Commissioner Stein, seconded by Commissioner Berkowitz to
offer incentive to homeowners to provide buffers.
Chairman Stulberg said that the plan already basically intends the incentive.
Commissioner Stein said that the cost of the incentive would reduce the overall cost in
the long run. Commissioner Thompson said that it is redundant to what is in the plan.
He said that he is afraid that if it is strictly voluntary homeowners would be just buffering
areas around swamps. Commissioner Berkowitz said that maybe assistance from the City
would've helped the dilemma that the Fosters' and Berglands' faced. Commissioner
Stoebner said that he would support the motion. Roll Call Vote. 6 Ayes. MOTION
approved unanimously.
MOTION to Amend by Commissioner Ribbe, seconded by Commissioner Thompson to
propose that additional wording be added "due to the scope of the plan and the
commitments that would be necessary to achieve the goals the Planning Commission
further recommends the determination of a reasonable estimate of the implementation
costs. Such costs should include the costs of land acquisition, controlling volume control
of natural waterways, and maintaining existing waterways."
Commissioner Ribbe said that before the City Council determines the final plan they
should have a handle on how to finance the plan and obtain the resources to meet those
costs.
Chairman Stulberg said he would vote against the motion as he believed the plan has to
happen anyhow and he didn't want to hold it up waiting to determine the financing
portion of the plan. He said that the plan will be a moving target that will continue to
change and will have to be monitored by staff. Chairman Stulberg stated that he would
support the recommendation, but not attached to the resolution. Commissioner
Thompson said that it is a good idea for a separate recommendation to the City Council.
Commissioner Stein asked if the financing portion could be decided before the plan is
adopted in August, 1999 and reported back to the Planning Commission. Director Moore
stated $8 million is a reasonable implementation of the plan. Commissioner Ribbe said
DRAFT
Planning Commission Minutes
November 10, 1998
Page #243
that there are portions of the $8 million that are too low that will disappear any time a
project comes along. He stated that the $120,000 for project acquisition seems low and
that it wouldn't go very far. Director Moore explained that most of the intended
acquisition is in the undeveloped part of the City and will be done in conjunction with
development. Commissioner Ribbe stated that the only significant dollar figures for
construction is related to Parkers Lake. There seem to be big gaps in the intent and how
it is going to get done. The City Council has to be willing to get their arms around the
entire project and be able to come up with the finances. Chairman Stulberg commented
that staff is saying that their estimates are realistic. Commissioner Ribbe said that there
are some items that could be big ticket items, but they don't seem to be dealt with in the
implementation.
Roll Call Vote on MOTION to Amend. 2 Ayes. MOTION failed on a 2 -4 Vote.
Commissioners Stein, Stoebner, Thompson and Chairman Stulberg voted Nay.)
Roll Call Vote on Main MOTION. 6 Ayes. MOTION approved unanimously.
Chairman Stulberg commended the Environmental Quality Committee and staff for their
work on the project. He said that he encourages the current City Council to deal with the
issue and not wait for the new Council as they have not been involved with the process to
date.
Commissioner Ribbe concurred, adding that the current City Council has the knowledge
to deal with the plan.

TO: Planning Commission
SUBJECT: Comprehensive Plan Amendment
Water Resources Management Plan (WRMP); (98114)
FROM: Fred G. Moore, Director of Public Works
On September 22, 1998, the Planning Commission held a public hearing on the Water Resources
Management Plan (WRMP). At the conclusion of the public hearing the Planning Commission had
several questions which they requested staff to provide answers before giving consideration on a
recommendation to the City Council on the adoption of the plan. Attached is a copy of the staff
report presented to the Planning Commission for the public hearing.
The proposed Management Plan is the first Comprehensive Water Resources Management Plan for
the City of Plymouth. The City has had a Storm Drainage Plan since 1972, which addressed the
flows and quantity of storm water runoff. This has been a very effective plan for the City. I am
unaware of any buildings which have been flooded from large rainfall events and the resulting
storm water runoff because of inadequate drainage systems.
The new plan not only continues the management of the quantity of storm water, but adds the very
essential element to deal with the quality of storm water. Although there has not been a
comprehensive plan, the City has implemented water quality requirements since 1995. Also in
accordance with state regulation, wetland protection has been implemented by the City since 1991.
The proposed Water Resources Management Plan combines all of the various elements into one
comprehensive plan. The Minnesota statutes require that each local government within the
metropolitan area develop a management plan which conforms to the plans adopted by the
watershed organizations. As a result of our natural drainage systems, Plymouth is part of four
watershed organizations (Bassett Creek, Shingle Creek, Minnehaha Creek, and Elm Creek). The
City's plan must implement the minimum requirements of each of the watershed organizations and
also conform and implement other mandates within state statutes, rules of the State Board of Water
and Soil Resources, Department of Natural Resources, Minnesota Pollution Control Agency, and
Metropolitan Council.

Comprehensive Plan Amenc nt (98114)
Page 2
Since this is our first comprehensive plan, I am sure that it will continue to require revisions over
the next several years as the plan is implemented. Although this will be the official plan of the
City, I believe it should be considered a work in progress as studies are completed and new
techniques evolve to preserve, protect, and improve water quality.
The plan does require the implementation of several goals and requirements as part of
development. Because of criteria in the Water Plan, I believe we can expect to see that continued
development, within northwest Plymouth, will be different than the development which has taken
place in Plymouth over the past 30 years.
Following are answers to the questions specifically requested by the Planning Commission:
1. Are there other cities that have a total ban on phosphorus fertilizer as recommended by
the EQC?
Plymouth, along with many other cities especially in the metropolitan area has an
ordinance that requires the use of phosphorus -free fertilizer for commercial businesses
or applicators. This ordinance does not cover individual property owners doing their
own work. A search through the Internet, by our consultant, by the City Attorney's
office and through the League of Minnesota Cities did not identify any cities which have
an ordinance for a citywide ban on fertilizer containing phosphorus. In discussing this
with the City Attorney's office, it is their opinion on a preliminary basis that it would be
legal for the City to adopt such an ordinance. There are currently proposals underway
either through the legislature or Metropolitan Council to have regulations which would
set an upper limit for phosphorus of one -half to one percent. Anything which Plymouth
does might need to be amended in the future to conform with action taken by the State.
The City Staff believes that the ordinance banning phosphorus fertilizer would be most
beneficial from an education standpoint. Most people when knowing the facts do not
intentionally violate a rule or law. We have also discussed with the City Attorney
whether we could make this apply to businesses which sell fertilizer within Plymouth.
His preliminary opinion after brief research is that this is probably unlikely. If it could
be accomplished it would probably be through some type of licensing requirements for
the sale of fertilizer within Plymouth. These licensing provisions would then contain
notification and education on the City of Plymouth's requirements. Just because
fertilizer is purchased within Plymouth does not mean that is where it's going to be used
and it may be acceptable in the community where the purchaser lives.
Staff still recommends the inclusion of this requirement in the plan as recommended by
the EQC because of its educational benefit.

Comprehensive Plan Amen nt (98114)

2. What is the percentage of the cost included in the plan associated with Northwest
Plymouth?
The plan includes an implementation/expenditure proposal for a ten -year period. This
expenditure includes the cost of many studies, water monitoring and investigation of
existing ponds, wetlands and drainage systems to determine their effectiveness for water
quality treatment. As a result of these studies we expect many additional capital
improvements to be identified which will continue beyond the ten -year implementation
period identified in the plan. As the plan is updated, the implementation expenditures
would also be updated and extended into future years.
Included within the plan is a projected expenditure for the ten -year period of
7,799,000. The portion of this cost which is associated with Northwest Plymouth is
1,128,000. As can be seen, this is approximately one - eighth of the expenditures. The
area of northwest Plymouth is approximately one - eighth the area of the City even though
the implementation plan was not proposed to be proportional within the different
portions of the City or watersheds. The majority of the cost indicated in the plan for
Northwest Plymouth, $900,000, is to purchase land for regional ponding facilities.
With current developments, each development is generally providing their own water
quality treatment facility. This can be done on a more effective basis if it is done
regionally within a watershed or subwatershed and not for an individual development.
The cost which the City would incur to develop the regional facilities would be
recovered from the developing areas either on a connection charge or by assessments.
We would not anticipate that the cost to develop regional treatment facilities for new
urbanization would be a cost paid for by the City at large but would be a development
cost.
3. Clarify the comment by the EQC of the water quality measurements in lakes between the
25' and 75' percentile for Ecoregion Lakes?
The WRMP includes lake atlases for eight major lakes in the City. For each of the
lakes, a qualitative comparison of the lakes current water quality is made to ranges of
representative minimally impacted lakes in the same ecoregion of the state. The
ecoregion ranges are based on the report entitled Minnesota Lake water Quality
Assessment Report, Second Edition, A Practical Guide for Lake Managers (Minnesota
Pollution Control Agency, 1990). The report presents statistical figures related to total
phosphorus, secchi disk and chlorophyll a. The report presents the complete data set
and expresses the typical data range as the lakes' concentration between the 25th and
75th percentile of the complete data set for representative - minimally impacted lakes.
In other words, the range is for higher quality lakes and does not include every single
lake in the ecoregion. This typical range is:

Comprehensive Plan Amen, nt (98114)
Page 4
Criteria 25th and 75th percentile for minimally impacted lakes
Total phosphorus 23 - 50 µg/1
Chlorophyl a (mean) 5 - 22 µg/1
Plymouth lakes may lie outside of the typical range listed above. The
Goal for Bass Lake is to reduce the phosphorus range to fall within
the typical range (above). The goal will be modified to reduce the
phosphorus value to at or below 50 µg/1
The goal for Bass Lake (Page 207) will change from: "Reduce total phosphorous and
chlorophyll a levels in Bass Lake to fall within Ecoregion range" to: "Reduce total
phosphorous level below 50 (ppb), and chlorophyll a below 22 (ppb)."
4. The EQC is recommending that the City identify all restorable wetlands. What are
restorable wetlands?
To be consistent with other publications, the water plan will define "restorable
wetlands" or "wetland restoration" the same as defined in the Minnesota Wetland
Conservation Act, which is as follows:
restoration" means reestablishment of an area that was historically wetlands but
currently provides no or minimal wetland functions due to manmade alteration such
as filling or drainage.
Once these areas, the restorable wetlands, are identified, they would be the most
logical /practical sites to establish new mitigated wetlands. A property owner would not
be required to restore the wetland.
5. What is the review /approval process and expected timeline and how will financing be
finalized? Does the plan commit the expenditure offunds?
This plan is the City's response to the Statute requiring surface water management
planning and requirements as part of our comprehensive plan for the Metropolitan
Council and watershed organizations. The various watersheds have review and approval
authority over our plan for its conformance with their water management plan which has
previously been adopted. The Metropolitan Council, DNR and the Pollution Control
Agency have review and comment authority. Their comments are made to the
watershed organizations and are considered by the watersheds as part of the watershed
approval process.
The following is a tentative timeline for this process which would bring the final plan
back to the City Council for adoption in August, 1999.

2. Review Comments submitted directly to the watersheds
The plan has an implementation schedule and financing plan but this does not allocate
funds. The City Council on an annual basis approves the City's operating budget and
the Capital Improvement Program which is the authorization for the expenditures of
funds. Once the expenditures are authorized by the Council, there are other City
Council approvals necessary for some of the expenditures such as approval of
construction contracts.
6. Provide more detail on the possible means of financing the $7,799, 000 included in the
ten-year implementation program for the plan.
As previously stated the plan does not specifically commit the dollars for the programs
upon adoption of the plan by the City Council. The spending will be committed during
the annual operating budget and Capital Improvements Program budget adoptions.
The City has always made expenditures for surface water drainage. Based upon a
conservative approach, we would estimate that there is an expenditure of $749,000 for
surface water drainage included within the proposed 1999 operating budget. Some of
these expenditures are for items that are proposed within the ten -year implementation
plan. The proposed 1999 budget under consideration by the City Council proposes an
additional expenditure of $100,400 in 1999 over and above expenditures being made in
1998 and previous years. These expenditures were proposed by the City Manager in
order to have funds as the first step in the implementation process of the water plan. Of
the $7,799,000 ten -year implementation plan, only $3,654,000 is identified as new or
additional expenditures beyond our current operating budgets and Capital Improvements
Program. If this is prorated over a ten -year period it is approximately $365,000 on an
annual basis.
N:\pw\Engineering\DEVLMNTS\98\98114\Memos\CompPlan—PinngRpLdoc
Comprehensive Plan Amenc nt (98114)
Page 6
The City Manager also identified as part of the 1999 budgeting process earmarking
portions of the Capital Improvement Levy for major water quality improvement projects
for the coming years. At the present time, this capital levy is $300,000 per year. As
was previously mentioned, $100,000 of additional funding was also included in the
operating budget for 1999. It may also be possible to include an additional like amount
within the 2000 and 2001 budgets to make a total of a $300,000 annual expenditure
above the 1998 budget devoted to implementation of the water plan.
The water plan includes discussion of several financing methods which are available.
These include:
Utility Fee
Growth and Tax Base
Bond Issue
Capital Levy
Special Assessments
The financing of the water plan will very likely involve a combination of the various
funding options. These options would be considered by the City Council as part of the
annual budget approval process. The additional funding necessary to implement the
plan as proposed would not require a substantial annual increase in existing
expenditures.
Mark Lobermeier, the consultant for the plan, Shane Missaghi, the City's Water Resources
Engineer and I will be in attendance at the Planning Commission meeting to discuss the water plan
and additional questions which the Planning Commission may have in their consideration of making
a recommendation to the City Council on the plan.
Attached is a resolution recommended for adoption by the Planning Commission. It is the same
resolution that was with the September 18' staff report except an Item 3 has been added. New
Item 3 is the recommendation that is included in Item Number 3 of this memo. The resolution now
addresses all items of the EQC.

REQUEST: Comprehensive Plan Amendment to add Water Resources Management
Plan
FILE NO.: 98114
1. PROPOSED MOTION:
Move to recommend approval of the Water Resources Management Plan.
2. DESCRIPTION OF REQUEST:
State law requires that the City prepare and adopt a surface water management plan as part of its
comprehensive plan. The plan that has been developed over the past three years would provide
the City with a comprehensive, pro- active approach for protecting water quality throughout
Plymouth.
Notice of this Public Hearing was published in the Official City Newspaper.
3. BACKGROUND:
In August of 1995, the City of Plymouth began developing the Water Resources Management
Plan. The main goals of the plan were to review the 1980 Storm Drainage Plan, to develop water
quality management provisions, and to meet the minimum standards of all agencies and
Watershed Management Organizations of the City with one city -wide uniform plan providing a
seamless coverage. Early on, the Plymouth Environmental Quality Committee (EQC) developed
and the City Council adopted the following Mission Statement as their guide in developing the
plan:
The Plymouth City Council envisions the community in which the quality of life is
enhanced by a natural and healthy environment and by infrastructure, designed and
maintained to protect property investment. Toward that end, the Plymouth Water
Resources Management Plan provides a single comprehensive strategy which addresses
the City's existing and future water resource needs in a proactive manner. The plan
Page 1 of 3
development promotes citizen and industry participation and education and provides clear
direction for properly managing quantity and quality of storm water runoff and surface
and groundwater resources. "
The plan has been regularly reviewed by the EQC members as well as presented at four public
information meetings to various neighborhood groups and lake associations. In February of this
year, the goals and policies of the plan was presented to the City Council. The Council reviewed
and approved the completion of the plan based on those goals and policies.
The main strategy of the plan has been to evaluate and rank the lakes and wetlands into high,
medium, and low priority. Eight lakes were evaluated and ranked based on various criteria in
three main categories of contributing watersheds, in -lake characteristics, and public use. The 38
sub - watersheds were rated based on the lakes' ranking, potential of land use changes, and the
extent of existing and potential storm water treatment in their existing ponds and wetlands.
These rankings were conducted as a general guide for future management decisions.
Ten city -wide goals such as finance, education, and erosion control and their corresponding
policies have been established which apply uniformly across the city. These goals are discussed
in depth in the Goals & Policies Chapter of the plan. In addition nine goals have been
established for each of the eight major lakes and Elm Creek, including an overall ranking and
intended use analysis which are discussed in the Watershed Assessment Chapter of the plan.
These goals are more site specific and respond closely to the needs and condition of each
watershed.
A unique feature of this plan has been the development of individual lake atlases for each of the
eight identified major lakes. Each atlas includes current and historical lake data, lake Trophic
State Index, water quality information, fish population, and an area map for quick references.
These lake atlases are located in the plan under each lake's corresponding watershed, such as
Parkers Lake in Basset Creek Watershed Chapter.
Environmental Quality Committee Comments
Attached to this report are comments on the draft plan that have been made by the Environmental
Quality Committee (EQC.) Many of these comments are technical corrections (such as
correction of spelling errors) and clarifications that are not considered substantive changes.
These changes will be made when the final draft of the plan is printed following Planning
Commission and City Council review.
The EQC has also recommended five substantive changes to the plan. Below staff has provided
listed each of these recommendations, along with a staff comment. New language is highlighted
in bold type.
Policy 1.1 (page 57)
The EQC is recommending an addition to Policy 1.1. The revised policy would state:
Constructed detention ponds should be relied upon to limit runoff to pre- development rates and
to control downstream flooding where feasible; natural basins and green corridors may also be
utilized." Staff concurs with this addition to the policy.
Page 2 of 3
Policy 1.1.15 (page 57)
The EQC is recommending a new policy for northwest Plymouth which states: "In NW
Plymouth, the Elm Creek stream flows will be limited to pre - development instream rates."
Staff understands that this means that the overall rate of flow within the stream will be
coordinated across the entire watershed. (The suggested numbering of the policy statement will
be verified in the final draft to make sure it is properly placed within the document.)
Policy 2.11 (page 65)
The EQC is recommending a new policy water quality policy which states: "The City shall
develop and adopt a City -wide ban on phosphorous base fertilizers."
The City has an existing ordinance that prevents commercial applicators from using phosphorous
base fertilizers. It will be very difficult for Plymouth to implement and police individual resident
applications until such time as there is a region -wide ban. However, staff does support the
addition of this language as a policy.
Policy 4.6 (page 75)
The EQC is recommending a new wetland policy which states: "The City will identify all
restorable wetlands." Staff concurs with adding this new policy to the plan.
Policy 7.4 (page 92)
The EQC is recommending a new maintenance and inspection policy which states: "The City
will develop a street sweeping plan." Staff concurs with adding this new policy to the plan.
4. RECOMMENDATION:
Staff recommends approval of the Water Resources Management Plan with the addition or
modification of the five policy statements as recommended by the EQC.

To: Members of the Planning Commission
From: David Shea, Environmental Quality Committee Member -Ward 2
On behalf of the Plymouth Environmental Quality Committee, I wish to recommend
your endorsement of the Water Resources Management Plan (Draft No. 5) with
the accompanying comments /corrections. Many years of effort have been invested
in this Plan and our Committee is anxious to see it adopted and implemented.
The Environmental Quality Committee Comments include corrections, clarifications
and five policy recommendations. We feel these policy recommendations are critical
to the Plan's success, establishing a comprehensive and progressive basis for decisions
on water quality and quality of life issues facing Plymouth residents. The five policy
reccomendations are:
1. Page 57, Policy 1.1
natural basins and green corridors may also be utilized.
2. Page 57, Policy 1.1.15
In NW Plymouth, the Elm Creek stream flows will be limited
to pre - development instream rates.
3. Page 65, Policy 2.11
The City shall develop and adopt a City -wide ban on phosphorous
base fertilizers.
4. Page 75, Policy 4.6
The City will identify all restorable wetlands.
5. Page 92, Policy 7.4
The City will develop a street sweeping plan.
The Environmental Quality Committee Comments did not reflect an important clarification
of water quality measurement in lakes we requested, namely that:
Transparency, phosphorous and chlorophyll a levels will be between
the 25th and 75th percentile for Ecoregion lakes.
We strongly urge your adoption of the amended/corrected Plan. A strong partnership
between the City, other governmental units, stakeholder organizations and all citizens
is needed to successfully address the issues, challenges and opportunities it presents.
Thank you for your consideration.

TO: Shane Missaghi, City of Plymouth
FROM: Mark Lobermeier
DATE: September 16, 1998
RE: Response to EQC Comments
651490-2000 800 325 -2055 651 -490 -2150 FAX
The following are my responses to the written questions provided by the Environmental Quality
Committee (EQC) at the August 11, 1998, meeting. The questions are numbered and bold. The
responses follow each question. These and other responses will be addressed in the next plan revision.
It should be noted that in the case of the policies, many hours of staff review have resulted in the
current language, culminating in a Council presentation on February 11, 1998. Each policy change
should be discussed further.
1. Page 15. Do not miss the opportunity to do the right thing in Plymouth.
The plan represents means and methods to do the right thing in Plymouth. No plan changes required.
2. Page 19. Can we organize Lake Data Summary by name or ranking?
The Lake Ranking Summary table will be re- ordered in order of appearance in the plan. Currently the
table is ordered by Watershed.
3. Page 20. Correct spelling of the word "exceptional" in the Wetland Types and Acreage
table.
Spelling correction noted.
4. Page 21. Please add: This file was used in determining hydric soils and other analysis which
has helped in developing this plan.
This file was not used in the manner suggested. The analysis sections of the plan provide a more
complete description as to how the wetland designations were used. See Watershed Assessment. No
changes required.
5. Figure 3. Soils. Can we have definitions for the soils data legend. ?
A better legend for the soils mapping will be provided.
6. Figure 6. Existing Land Use. Please define legends. 'A
Abetter legend for the existing land use mapping will be provided. rf

7. Pages 44 and 45. Expand on items 7,11,14,15 and 24.
This listing was developed during discussions with the EQC, brainstorming on general water
resources issues. The list is a direct replication of the issues identified. For clarification, the following
amendments are suggested.
7. Balance [between development and environmental protection.]
11. Benefits [of water resources management strategies]
14. Enhance and protect [the environment]
15. Distribute information [about water quality and environmental protection issues]
24. Identify and establish natural environmental corridors through integrated resource management
see page 48]
8. Page 54. Please reword paragraph under Documentation Still needed.
The reworded paragraph:
The typical urban drainage system rarely has a complete physical inventory. Our 1980 Storm Drainage
Plan included the existing basic trunk drainage system information and suggested a planned
configuration for the future drainage system. Today, a storm sewer base map provides a detailed
index to construction as -built drawings. However, the Engineering Data tables in Appendix F are
missing considerabie amounts of pond data for many of the City's 900 water bodies. Before accurate
budgeting and meaningful decision - making can occur, the basic drainage system information must
be obtained. The GIS is a perfect tool for managing the data.
9. Page 57. Policy 1.1. Add green corridors to this text.
Green corridors do not necessarily fall under the Water Quantity Goal or Policy 1.1. Clarification with
the EQC, as well as with the staff and Council who have both given preliminary approval to the goals
and policies, will be needed to amend the plan as suggested.
10. Page 57. Policy 1.1.15. Add this Policy: In northwest Plymouth, the Elm Creek stream flows
will be limited to pre - development rates.
Clarification with the EQC, as well as with the staff and Council who have both given preliminary
approval to the goals and policies, will be needed to amend the plan as suggested. Also see page 159 —
Table 49 — Elm Creek Action Plan; the goal is to maintain the existing (1997) quality and rate of
runoff in Elm Creek.
11. Page 60. Simply. Remove this sentence: It is so tightly bound to soil particles that it is
unavailable to leaching. Under Regulatory Controls: change word "against" to "for."
The sentence will be deleted. "Against" will be changed to "for."
12. Page 65. Policy 2.11. Add this policy. The City shall develop and adapt a City -wide ban on
phosphorus based fertilizers.
Clarification with the EQC, as well as with the staff and Council who have both given preliminary
approval to the goals and policies, will be needed to amend the plan as suggested.

The changes will be made as noted. The measurement in each task is discussed in Table 21.
Measurement may be nothing more than reporting on the status of the task.
24. Page 81. Sixth bullet should read: Emphasize public health and safety. Use the word
monitor" rather than "manage" in bullet nine and ten. Add another bullet reading
Promote land use designation that preserves wildlife.
Public health and safety and wildlife are not issues related to the monitoring goal of the plan. Bullet 9
will be amended.
25. Page 82. ??
Comment not clear
26. Page 83. Remove last sentence under macrophytes. Remove "sample twice in June and
twice in August" under algae. Remove "sample mid to late May and late August" under
phosphorus. Remove remaining text after the word hydrology.
It is not clear as to why these changes are being made. However, since the discussion is "indicators
of wetland dynamics," the deletions will be made as suggested.
27. Page 86. Change "no" to "yes" under more than 5 years of data for Medicine Lake.
The table will be so amended.
20. rage 9 "v. Remove bolid from third bullet. Ad J "as a last resort" to bullet four.
Bold was added for emphasis, but will be deleted as requested. The "last resort" comment is
inconsistent with the recommendation. No change is recommended.
29. Page 92. Add Policy 7.4: Develop a street sweeping plan.
Clarification with the EQC, as well as with the staff and Council who have both given preliminary
approval to the goals and policies, will be needed to amend the plan as suggested. This change fits
well with Table 28.
30. Page 103. Change word "from" to "form' ' in first sentence.
The changes will be made as suggested.
31. Page 109. Add No. 4 — Work with Park and Rec. to identify wildlife?
Clarification with the EQC, as well as with the staff and Council who have both given preliminary
approval to the goals and policies, will be needed to amend the plan as suggested.
32. Page 112. Reword Policy 9.6.
Clarification with the EQC, as well as with the staff and Council who have both given preliminary
approval to the goals and policies, will be needed to amend the plan as suggested.
33. Page 113. Remove the words "and monitoring" from No. 6 under Activity Steps. Add No. 8
Work with park and rec. To use alternative landscapes on all City projects.
No. 6. has no recommended change.

Against" will be changed to "for."
16. Page 71. Bad language. Spell out BWSR under Current Wetland Plan.
Acronyms are used throughout the plan. An index is provided in the plan. The bad language comment
is too indirect to respond to. BWSR can be spelled out to make the plan more readable,
17. Page 72. Bad language. Correct punctuation in the first sentence under: Wetlands Selected
for Management.
The bad language comment is too indirect to respond to. The period at the end of the first sentence
will be deleted.
18. Page 75. Reword the sentence under "Purpose."
Clarification with the EQC, as well as with the staff and Council who have both given preliminary
approval to the goals and policies, will be needed to amend the plan as suggested. The concern may
be over the word utilize. The word simply recognized how wetlands are currently integrated into the
City's storm water system.
19. Page 75. Policy 4.4. Where do we say the different bounces on different types.
The plan assumes that this will be one of several issues developed in the City's comprehensive
wetland plan.
20. Page 75. Policy 4.6. Add this policy: The City will identify all reasonable wetlands.
Clarification with the EQC, as well as with the staff and Council who have both given preliminary
approval to the goals and policies, will be needed to amend the plan as suggested.

Wu --r Resource Management Plan mments
SEH No. A- PLYMO9504.02
Based on my review of comments forwarded to me in your letter dated August 4, 1998,
the following are my general responses. Specific responses will be documented as part
of the plan revision process which would include a legislative style edit as previously
discussed.
Mark Lobermeier, SHE Inc.
Association of Medicine Lake Area Citizens
If available, the notation of the Bassett Creek Watershed Management Commission ?s
1998 goal for phosphorus will be included in the goal statement, both on page 6
and in the Lake Management Plan section under Bassett Creek.
2. Additional clarification as to the in -lake ranking of Medicine Lake can be provided
with more direct reference to Appendix A.
In general, the schedule for and the scope of the Water Resource Management Plan
were to result in a comprehensive plan to be carried out over the next 10 years. The
plan was not intended to provide a specific detailed research and study and /or
feasibility level analysis of specific improvements.
Friends of Parkers Lake
1. Discussion of planned improvements to be constructed in 1999 may require
amendment based on the approval process for this plan and prioritization of other
improvements. The dates in Table 104 on page 276 must be considered preliminary
at this stage.
2. No feasibility studies were completed in 1998 as referred to on page 276. The dates
in Table 104 were originally generated over a year ago. The likely completion date
for the feasibility study will be 1999. It is possible that both feasibility and
construction could occur in calendar year 1999 depending on City budget.
3. The power boating policy is a familiar theme throughout all the lake action plans.
The issue is a controversial one but is not a "do nothing" task. It is anticipated that
lake homeowner associations and the public would participate in policy
development.
4. The activity steps support Eurasian water milfoil. The program is intended to
illustrate continued financial support of DNR efforts to control Eurasian water
milfoil on the lake.
5. During the preparation of the plan, no specific problems related to curly leaf pond
weed were identified. However, additional discussion could be added at the
direction of staff.

PLY_NT\ntdiskl \pw\ Engineering \WTRRESRC\WPLAN\1998 \Water Resource Management Plan Comments.doc
6. In -lake dredging is typically not a permitted activity by the Department of
Natural Resources. While dredging would remove sediments and the associated
pollutants, the improvement would do nothing to reduce the amount of pollutants
entering the lake. The intent of the BMP study listed as Activity Step 3 in Table 104
would be to study the issue further and come up with the most feasible
recommendation(s).
7. Page 266 under Completed Studies and Problem Assessment - the last sentence will
be changed to read "Additionally, Eurasian water milfoil continues to be present in
the lake, but has been controlled through past efforts of MNDNR."
8. Page 268, Table 100 - the table has been corrected in the column under the
heading "Current" with reference to the Lake Atlas the total phosphorus
concentration should be 48 ppb rather than 44 ppb, chlorophyl a should be 37 ppb
instead of 16 ppb and the Secchi disc transparency should be 2.1 meters rather
than 3.28 meters. This change was based on a change made to the Lake Atlases
during plan development. The current numbers on the Lake Atlas, which appears
on page 273 are based on 1993 to 1995 data.
9. Page 268 - sections of the paragraph will be modified to indicate "While each of the
options resulted in improvement in water quality, the analysis concluded that the
lake goals cannot be met." This change deletes reference to combinations of
options in the current text. The analysis completed by Barr in 1993 did not
indicate in -lake concentrations of phosphorus for the combinations of BMP
options. Therefore, no judgement can be made related to the effectiveness on
lake water quality by combining any of the options. The results of the options are
not additive. Page 269, last sentence, should read "therefore the 2, 3, 5
combination is recommended for further study" This is a typographical error.
Mooney Lake Association
1. Information included in the July 28, 1998 letter received from the Mooney Lake
Association could be incorporated into page 370 under the subheading of
Completed Studies." 2. The Lake Management Plan recommended an Activity
Step 1, Table 153, page 376 would address the water quality and cost problems in
the July 28, 1998 letter.
2. Septic systems are intended to be addressed by Activity Step 4, Table 153, page
376.
1. 4. The water level study and the need to construct an outlet for the lake are
recommended on the basis of a study completed by the Minnehaha Creek
Watershed District in 1995. To develop a proper solution, up -to -date information
will need to be used.
Bass Lake Improvement Association
1. The solution of further study is in keeping with the original intent and scope of the
Comprehensive Water Resources Management Plan.
Page 2 of 5
PLY_NT\ntdiskl \pw \Engineering \WTRRESRC\WPLAN\1998 \Water Resource Management Plan Comments.doc
2. The efforts of the Bass Lake Improvement Association will be added to the text.
3. Addressing the comment on page 2 regarding purpose and the need to add
repair /reconstruction of old marginal storm sewers is properly addressed via Goal
10 - Establish Funding Sources to Finance Water Resources Activities. Staff
continues to depend on the 1980 Comprehensive Storm Drainage Plan and the
existing storm drainage system with updates periodically to handle the quantity of
storm water. No specific problems regarding old or under capacity storm sewer
systems were defined during the planning process.
4. Table 1 on page 3 "Lake Ranking Summary" could be reordered as suggested.
The original intent in ordering in the table was to write the ranking in the order of
discussion in the plan. While the lakes are ranked in the order of the watersheds as
they appear in the plan, the lakes in the Shingle Creek Watershed appear in the
plan in the following order; Pomerleau, Schmidt, Bass, and last Pike.
5. The lake ranking process included three main categories - watershed, in -lake, and
public use elements. Across these three categories, a total of 12 different factors
were utilized for determining lake rankings. Based on the lake ranking process
described in Appendix A, Bass Lake ranks high in terms of watershed category,
medium in terms of in -lake ranking, medium in terms of public use rank, and
medium in the overall composite rank. In reviewing the public use ranking in
specific, Bass Lake was given credit for carry -in access, full service City Park
facilities, and full body contact as a current use, the composite public use rank is
third behind Medicine Lake and Parker's Lake. The lake ranking was done by
SEH and reviewed by City staff. The DNR did not participate. The ranking builds
on similar lake ranking projects in other communities, including Maple Grove.
6. Page 6, Goal 14 for Bass Lake - the goal statement evolved over several months
and meetings among City staff. The current goal, to reduce total phosphorus and
chlorophyl a levels in Bass Lake to fall within ecoregion range, encompasses the
comment to address retrofit of storm sewers with more efficient detention ponds
and reducing phosphorus loadings at storm water inlet points. No change is
anticipated. However, specific studies recommended in the plan would address
the specific issues as noted in the letter from the Bass Lake Association
7. City staff reports that the 1980 plan continues to serve the City well in terms of
overall conveyance of storm water. The Bass Lake Association comments relative to
the 1980 plan seem to be more water quality oriented. Staff does not feel that the
1980 plan needs to be revised. However, Staff does believe that the water quality
improvements identified in this plan need to be implemented. The 1980 plan
addresses only one element of water resource management, that is water quantity.
The current plan is intended to fill in the gap related to water quality and address
issues such as grit chambers, storm sewer outfalls and so forth. New
development standards suggested by the Bass Lake Association fall under planning
and zoning within the City. Many similar requirements already exist for
developments.

PLY_N \ntdiskl \pw\ Engineering \WTRRESRC\WPLAM1998 \Water Resource Management Plan Comments.doc
8. Bass Lake Mal. It is unclear as to which Bass Lake m '.s being referred to in
the comments. Figure 42 depicts the depicts the contributing subwatershed to
Bass Lake and includes a map of the lake itself as well as adjacent wetlands. The
Lake Atlas on page 205 illustrates Bass Lake proper and may or may not show the
lagoon area as indicated in the Bass Lake Association letter. The vegetative
data shown in the Lake Atlas was based on the best available data at the time the
plan was completed. The information in the Lake Atlas is not based on a separate
vegetative survey of the lake. If additional documentation is available, the Lake
Atlases can be updated as suggested.
9. If a DNR Fish Management Plan was competed in 1996, it can be included in
the plan. The analysis and research for the Lake Atlases was completed in late
1995 and early 1996.
10. The status of winter kills on Bass Lake will be noted in the plan. The Lake Atlas
already indicates that winter kill status is occasional, prevented through aeration.
11. The back page of the Lake Atlas explains the thought behind a fishery being an
indicator of water quality. The Lake Atlas may appear to have a contradictory
element with the fish populations of 1991 showing very good levels of Northern
Pike as opposed to the statewide fish abundance versus trophic state index chart on
the second page showing Group 1, which includes Northern Pike, to be low in terms
of relative fish abundance. This discrepancy will be reviewed prior to completing
the plan.
12. No specific data has been previously provided from the Bass Lake Improvement
Association related to trophic state and water quality monitoring. Acknowledgment
of the Association's existing efforts will be made based on information provided.
13. Page 202 will be revised to give credit to the Bass Lake Improvement Association
for stocking of fish, based on information provided by the Association relative to the
stocking programs.
14. 14. The in -lake ranking of Bass Lake is based on five factors; fisheries profile, water
clarity, lake depth, lake area, and total phosphorus concentration. In terms of
fishery profile, Bass Lake ranks third behind Parker's and Medicine Lakes,
from a water clarity prospective, Bass Lake ranks second behind Parker's Lake
and tied with Schmidt and Pomerlau Lake, the lake depth category shows Bass lake
tied for first with Schmidt Lake, Pomerlau Lake, Parker's Lake and Medicine Lake.
The lake area factor shows Bass Lake tied for second behind Medicine and tied
with Gleason Lake and Mooney Lake, and from a total phosphorus concentration
standpoint Bass Lake is tied for second behind Schmidt, Pomerlau, Harpers and
Medicine all tied for first with Bass being tied with Pike Lake.
15. The overall in -lake composite rank shows Bass Lake to be fifth in the ranking
behind, in order, Parker's Lake, Medicine Lake, and Schmidt and Pomerlau
Lakes (tied). Bass Lake's overall in -lake composite rank places it ahead of Pike
Lake and Gleason and Mooney Lake.
Page 4 of 5
PLY_NT\ntdiskl\pw\ Engineering \WTRRESRC\WPLAN\1998 \Water Resource Management Plan Comments.doc
16. The statement . . the bottom of page 202 may be dece a in that Schmidt and
Pomerlau Lakes though ranked ahead in terms of in -lake conditions, are ahead by
only 2 percent in the overall scoring. In fairness, this statement could be removed
from the plan. What is more important than the in -lake composite rank is the
overall ranking of Bass Lake as medium. It is the City ranking that is used to
prioritize future City activities. In this case, the actual numbers will not be
used, but the overall City ranking classification (high, medium, low will be used).
17. A statement regarding the applicability of treatment within SC 27 will be added to
page 203.
18. Page 207 regarding City ranking. See response Nos. 5 and 14 above. 17. Activity
Step 1, Complete Study of Internal Lake Loading" and Activity Step 2, "Prepare
Feasibility Study Regarding Storm Water Treatment Options" would address the
point site monitoring study referred to in the Bass Lake Association letter.
There is information regarding aquatic plant management (harvesting being one
method) beginning on page 101 of the plan. A specific harvesting plan could be
developed for Bass Lake. Harvesting is much like lawn care. Harvesting activity
merely controls the degree of vegetation on a temporary basis. Approximately 5
to 15 percent of total cuttings cannot be cleaned up because of wind and wave
action that wash vegetation away. Another approach as opposed to using a weed
harvester is to use a cutter which does not stack the plants on the back of the
mechanical unit like they are with a harvesting unit. 18. Page 207 additional
fishery information beyond the 1991 data utilized in the plan will be utilized to
make plan revisions if available. The statement appears to be accurate based on the
1991 data. Any additional information will be utilized in the plan. It is
recommended that the Association meet specifically regarding new information
related to fisheries or water quality that they may have on record.
19. Table 28 "Maintenance and Inspection Implementation Plan" on page 93 of the
Water Resource Management Plan addresses street sweeping. Activity Step 4
developed a prioritized plan for street sweeping areas directly contributing to
sensitive water bodies would appear to address the Bass Lake Association "s
concerns related to street sweeping.
20. Table 21, Public Participation, Information and Education Implementation Plan
on page 80 addresses the Bass Lake Association ?s concern over an education
campaign. 21. Related to Activity Step 2 in Table 72 on page 208, prepare
Feasibility Study......, the Bass Lake Association will be shown as a resource to be
utilized during plan preparation.

Plymouth Water Resources Management Plan
Sh
We are pleased that the Water Resources Management Plan (the Plan) is in the final
st es. For those of us awaiting help for Parkers Lake, it has seemed like a very drawn out
Process. We are particularly amazed at the lack of original research over the several years
it I as taken to complete the Plan.
In he same vein, many of the recommendations are for further studies. After all this tinge,
it E eems like everything is studied ad infinitum, with little recommendation for action. That
sal J, we are pleased to see that some improvements are to be constructed in 1999. We
w uld like to know more specifics about what those improvements are. Are they on track
an will the funding be in place? To be consistent, in Table 104 on page 276, under #2,
vity Steps, it should say "construct improvements" since constructed improvements
is ne ofthe measurements.
WJ need access to the conclusions of the feasibility studies that are to be completed in
19087 Mere I refer to the studies shown under #2 and #4.
w 06 as a kind of a "nothing" statement. I sincerely believe that the DNR will not
ate from their "one -size fits all" mentality regarding lake usage. I hope someone
es me wrong! Some states designate a couple weekends a month for no motorboat
ic. Something like that would be a stan .
n number 5 is probably not a very actionable statement. Due to the circular shape of
kers Lake, the milfoil has again invaded virtually the whole circumference of the lake.
y the. two bays and the swimming area can really be isolated enough to treat. Due to
limited percentage of littoral area (— 15 %) that can be treated at a time, any
mingffil control would be unlikely. Harvesting may make some sense, just to reduce the
E)'7/31/1998 12:56 6129358956 CARTER &SHIELDS PAGE 03
Aca,f pond weed should probably have been mentioned as a problem on page 275. I
recently ;read some articles about harvesting the curly -leaf, again to reduce the
ass at the time of the die -back and to thereby improve water quality.
Aoin4 as part of the solution to problem number 3, the 96" storm newer, dredging
J, ready accumulated settlement should be considered. Due to the run -off directly
unty Road 6, the city should seek partial funding from the county to correct this
degradation of the lake.
On page 266, in the first paragraph under Completed Studies and I!rob)em Assessment, the
last sentence should be modified to more clearly reflect that the milfail was controlled by
the Sonar treatment, but is presently again widespread in the lake.
On Ipage 268 in Table 144, why is the Secchi goal lower (2.2 meters) than the current
S hi (3.28) meters? Did these numbers get transposed?
on page 268, Z was surprised that 33% of the watershed drains through wet detention.
study quotes ,Barr, but I didn't think there was that much filtration.
T fo ind the last complete paragraph on page 268 confusing. In the second sentence it says
W i9e each of the options and combinations of options (my italics) resulted in
iml overaent in water quality, the analysis concluded that lake goals cannot be met." Then
in t te last sentence it states "Therefore, a combination of options appears necessary to
ac Ev+e the Parkers Lake water quality goal." Somehow these statements seem
ja ctory to me. Why would a combination of options be necessary when above it says
ev= with a combination of options the lake goals cannot be met?
Air her confusing statement, beginning with the last sentence on page 268: "However, the
2,3 ,4 combination has a significant annual cost in comparison to 2,3,5. Therefore, the
2,3 ,4 combination is recommended for further study." Why would the City do further
stu#y on the more expensive combination?
In Conclusion, we do hope the City will fund the necdad improvements for Parkers Lake.
Th Board was encouraged by the plan for some constructed improvements in 1999.

Dear Mr. Missaghi;
We in the Mooney Lake Association (50 out of 53 lakeshore owners)
appreciate receiving your tentative plans for Mooney Lake. In general they
are in keeping with our desires; however some of the assessments of
conditions on Mooney Lake need updating. In 1960 Mooney Lake was over
6 feet shallower than it is today (about 982 feet above sea level). With
the development of the Mooney Lake Watershed area, run -off has greatly
increased. The DNR established a high water mark in 1976 of 988 feet
above sea level. This has been used in establishing building codes etc..
Since that time the Lake has risen at times exceeding 990 feet above sea
level and shows no signs of stabilizing out. With the increased depth the
character of the Lake has changed. Mature hardwood trees have been
drowned out; aquatic growth has been curtailed by the very abrupt
shoreline resulting in fish kill; and during the past three years the water
clarity has varied from 13 feet to 2 feet. At times the clarity exceeded
that of Lake Minnetonka.
In regard to the five problems and solutions listed for Mooney Lake, we
present the following comments:
Problem 1) - water quality - It appears that the water fed into the Lake
through the storm sewer on the North side of the Lake is loaded with
phosphorus causing extensive weed growth in it's vicinity. Mooney Lake
was definitely swimable in the 1960's and sustained a rather large bass
population.
Problem 2) - cost- The problem for the most part is generated by those in
the Mooney Lake Watershed, and as a result all should partake in any
solution.
Problem 3) - septic systems The septic systems in the south and west
sides of the Lake have been checked from time to time. All property
owners have relatively large land tracks and septic systems have been
well maintained. However, there is concern about the pumping system in
Imperial Hills when electric power is lost. Effluents have been seen
running into the Lake due to overflow.
Problem 4) high water - hopefully updated information will be used in
the study - AND - if the study supports our concerns, action to alleviate
the situation should be taken before loosing several homes.
Problem 5) - power boating - This has been resolved with all three
communities: Plymouth, Orono, and Medina agreeing to limit all use of
motors to Shp or less.
Again we want to thank you for solicitating our thoughts on the
Plymouth Water Resources Management Plan. We look forward to working
with you to resolve the various Mooney Lake problems.

Water Resources Engineer
City of Plymouth
3400 Plymouth Blvd.
Plymouth, MN 55447 -1482
Dear Shane:
Thanks very much for your letter of July 10 and the Water Resources Management Plan
draft material. The points regarding Schmidt Lake are similar to earlier draft pages you
provided us that were discussed at the annual meeting of the Schmidt Lake Improvement
Association in March of this year. As the current volunteer President of the Association,
I am submitting this letter to comment on the Plan draft based on discussion at the March
meeting and ongoing dialogue within the Association since we learned of the Plan via
public meetings in summer of 1996.
The comments in this letter focus on five potential action items related to points
mentioned in the Plan draft. The Association encourages the EQC to consider these
action items. Subsequent paragraphs of the letter provide background on the current
situation of Schmidt Lake and discuss the five potential action items. The five items are:
1. "Install a modular Storm water treatment system at discharge points to the lake
Schmidt Lake]...." (p. 189)
2. As one "treatment option" (p. 189) provide alum treatment to reduce phosphorous
content in Schmidt Lake.
3. Regarding "treatment ... costs and impacts on homeowners," (p. 189) provide support
for ongoing Association activities such as the current treatment program, lake
monitoring, and distributing water quality information.
4. Continue and expand support for phosphorous -free fertilizer. (p. 189)
5. Fish stocking. (p. 185)
Background on Schmidt Lake and the Association
The Schmidt Lake Improvement Association's purpose is to take long -term and short -
term action to preserve and enhance the quality of Schmidt Lake as a resource for
recreation, wild life, and esthetic enjoyment, and to maintain neighborhood property
values.
Regular Association activities include monitoring lake water clarity and temperature.
Samples are taken to test for levels of chemicals such as phosphorous. Association
volunteers annually distribute information to all Schmidt Lake watershed residents on
water quality issues such as lawn care and runoff. The Association also undertakes some
all watershed residents on water quality issues and the City's efforts to reduce or
eliminate use of fertilizer with phosphorous.
The draft Plan states "Numerous (eight) inlets feed Storm water directly into Schmidt
Lake without the benefit of pretreatment. Few areas exist ... where NURP ponds could
be developed without costly property acquisition." (p. 189) Only one settling pond was
established in the course of developing the area around Schmidt Lake. The Plan draft
states existing settling pond area is 0.37 acres (p. 183) with a deficiency in settling pond
area of 2.3 acres. (p. 186)
1. Storm Water Treatment System
Based on conversations with you, it is our understanding that a "great room" can be
added to an existing storm sewer in many situations where a settling pond is impractical
due to development having occurred without appropriate pond space. Based on our talks
with you, we understand the approximate cost per great room is $15,000, including the
cost to acquire a small right of way to install the great room. At this cost per module,
total cost to retrofit Schmidt Lake would be roughly $100,000.
The deficiency of settling ponds occurred in the course of the development of Plymouth
over the last three decades. The current work of the EQC offers an excellent opportunity
to focus appropriate City resources to remedy the situation. Either great rooms or some
other modular treatment solution would appear to be much more feasible than attempting
to acquire real estate for settling ponds.
2. Alum Treatments
Estimated cost of a lake -wide alum treatment for Schmidt Lake is $15,000. Per our
contacts with various water resource and treatment professionals, alum treatments
remove phosphorous to a degree that could improve Schmidt Lake quality in the near
term and possibly reduce the need for other treatment for a three to ten year period after a
given alum treatment. Improvements such as a modular storm water treatment system
and ongoing reduction or elimination of undesired nutrients in fertilizer could then work
to decrease major sources of undesired nutrients in lake water. In turn, these measures
could reduce the future need for lake treatment or result in improved quality without
increased treatment.
Of course, alum is not the only treatment alternative. The Association has also obtained
estimates on mowing aquatic weeds. This option was dismissed as both costly and a very
short-term measure. However, treatment or improvement options which act to eliminate
underlying problems such as phosphorous levels rather than merely dealing with
symptoms or effects on a short-tern basis would be of interest to consider.
5. Fish Stocking
The summer of 1997 saw a conspicuous absence of bass and sunfish in Schmidt Lake and
a glut of bullhead minnows. DNR contacts informed us that 1996 -97 was the worst
winterkill in 20 years. This spring, the Association restocked the lake with over 200
sunfish and 200 bass of varying sizes at a total cost of $600. The bullheads have
practically disappeared this year, which is probably related to restocking the bass
population.
Other species such as northern pike seemed relatively unaffected by the winter of 1996-
97. However, City activity to investigate and implement appropriate further stocking of
desirable species would be welcome.
In summary, while we are confident that the Association has and will continue to have a
positive effect on the lake, we believe that City involvement in issues beyond the scope
of the Association can make a crucial difference in maintaining Schmidt Lake as a
valuable resource for Plymouth going forward. Thanks for your help over the last two
years in providing maps and documents, coordinating water sample testing, and taking
time to talk with us both on the phone and in person. We look forward to working further
with you and the EQC to help realize the goals of the Water Resources Management
Plan.
Sincerely,

SUBJECT: PLYMOUTH WATER RESOURCES MANAGEMENT PLAN
Dear Shane Massaghi:
The officers of the Bass Lake Improvement Association (BLIA) were pleased that you solicited our
comments on the City Plan. As secretary, I duplicated everything that you sent to me and sent out copies to
each of our officers and to the H2O Quality Committee, as well. The report that accompanies this letter is a
composite of the comments made by each of the concerned Bass Lake homeowners.
Collectively, we felt that the Plan does a good technical job of characterizing Bass Lake, its role in the
watershed and the outline (organization) of the plan is very well done. We agree with most of the priorities
set forth in the action plan, but the solutions noted are only to study the problems -no real (reduction to
practice) actions are noted. Our lake is unique in its problems and solutions because the DNR has no
access and maintains controls over problems and solutions but offers little or nothing in monetary help. As
homeowners, we wish to be able to consult the state, the county and the city but we like the grass -roots
level ability to control. Sometimes this causes us monetary problems such as having to re -stock the Bass
fish population in 1996 due to excessive outside winter ice fishing with no policing from the DNR. We
also maintain a winter aeration system to avoid winter fish kill. We realize this is the price we must pay
and we applaud the City of Plymouth in trying to help us maintain the quality of Bass Lake.
We feel that the report we have prepared is complete however, we would like to present questions and
statements at the August 11, 1998 meeting as well. We are looking forward to meeting with the EQC.
Together, we can save our precious water resources.
Thank you for sending us this draft.
Truly yours, -

PLYMOUTH WATER RESOURCES MANAGEMENT PLAN: Comments from Bass Lake
Representatives
Executive Summary" pages 114
Page 2 — under "Purpose" add: repair /reconstruction of old, marginal storm sewer
systems to protect and improve surface water resources. May be added as follows:
Storm water treatment requirements for new /old development and reserve
funding to repair /reconstruct old, marginal storm sewer systems to protect and
improve surface water resources.
Page 3 — perhaps the lakes on the Lake Ranking Summary should be in alphabetical order
or in order from low to medium to high ranking. There seems to be little reason for its
current order of appearance.
We question the ranking of Bass Lake. Why were we ranked at Medium? Is the
large boat access the only thing that keeps us from the High rank? We DO have park
access, small boat and motor access, and canoe /small sailboat access. How heavily does
this count in the ranking ?. Was this "Lake Ranking Summary" done by the City of
Plymouth or the DNR? What weights did each criteria carry? Can we see a ranking?
Page 6 — Bass Lake add the following: Retrofit storm sewers with MORE EFFICIENT
detention ponds where feasible. Reduce phosphorus loadings at storm water inlet points.
I have been informed by a city engineer that a culvert (on a holding pond owned
by DeCoursin and abutting the Darth property on the western edge of Bass Lake) was
placed facing a direction that causes pond shore erosion, the death of valuable old oak
trees, and the inability of aquascaping plants to take hold. What can be done to remedy
or reconstruct this holding pond area? A huge hill to the west of the pond empties into
the pond. During heavy rain storms the pond overflows and has actually overflowed into
the abutting road and directly into Bass Lake.

Page 7 — Regarding the statement: Developing parts of the City will still be addressed by
existing rate control and storm water treatment requirements that are in place today, and
by the 1980 storm drainage plan." The following comments are relevant to Page
13 ... "Future Needs of the City" "Developing Plymouth" "Developed Plymouth"
The 1980 plan is almost 20 years old. Perhaps it should be redone considering
we are moving into the 21' century and there are new methods based on new research
and knowledge concerning lakes, wetlands and prairie potholes. Is it time to redo the
1980 Plan? How can we facilitate this?
Our concern is that the Bass Lake watershed is approximately 50%
undeveloped at this point. By using a 1980 plan for storm water sewers we are asking for
the death of our lake. Let's use new methods as they present themselves, such as grit
chambers on lakes such as Pomerleu. We must also answer the question presented on
Page 11 — "Should development be controlled to preserve significant nature features ?"
Perhaps new development could be legislated to use prairie or aquascaping in 20 to 50%
of the yard acreage just as developers demand cedar shingle roofs, no vehicles in
driveways etc.
Page 8 — Change word in paragraph "these watershed" to `watersheds"
Page 14 - Bass Lake Improvement Association wholly concurs with the strategy that the
City must first focus on pollution prevention followed by water quality treatment. As a
group we have used treatment since 1970 and the water quality only becomes worse due
to increased development, focus, by an uneducated public, on perfect lawns acquired
through the use of chemicals advertised through expensive marketing moguls. WE
MUST EDUCATE OUR NEWEST CITIZENS. THE CITY MUST USE SOME OF ITS
FUNDS FOR CITIZEN EDUCATION. We must use the State of Minnesota Dept. of
Agriculture to rework old rulings with the blessing of our legislature. WATER IS OUR
MOST PRECIOUS RESOURCE. It is taken for granted by our populace.
BASS LAKE MAP (This reproduction of an old map by the DNR/Montgomery Watson
Metropolitan Council Report is unacceptable. The Montgomery Watson Report merely
used old DNR maps /and information for its report. It does not recognize the largest and
deepest lagoon and channel on the lake. This lagoon and channel has existed since 1969.
Chip Welling says that the DNR now recognizes the lagoon as a body of water and not
just a wetland or lower elevation storm water drainage area. This large acreage lagoon
needs to be recognized. On this map it looks like a road or extended property. No water
appears to be present. If this is a CITY OF PLYMOUTH REPORT, do not just coy old
DNR maps. Create your own with current accuracy. Our taxes indicate that we are on
water or at least wetland area.

Abundant Aquatic Plants (add the following)
Wild Celery
Northern Milfoil
Coontail
Exotic Aquatic Plants
Eurasian Milfoil
DNR Fish Management Plan (Should have been done again in 1996. This is very old
information. There were five hundred 3 1/2 Bass fingerlings, paid for and added by,
Bass Lake Improvement Association in 1997. We stocked heavily at least one other
time in the last 15 years.
Winter Kill Status
Twice. (Now prevented through aeration by Bass Lake Improvement Association
volunteers and funding. Please give us the credit due to us for our support of Bass
Lake since 1970.)
Why is Bass Lake's Fishery an Indicator of Water Quality?
The statement: "The low percentage of Northern Pike (Group 1) and high proportion
of Group 3 (black Bullhead and Black Crappie) species reflect both the lake's
marginal spawning habitat and moderate water quality."
This statement is a contradiction to the "Fish Population — 1991" chart on the
other side of the page, that says that Northern Pike are `very good ". Indeed, in 1996,
the word, concerning the huge numbers of pike and bass, spread to NON -LAKE
residents during the winter and we had huge numbers of non - residents accessing the
lake via City owned Timber Shores Park. The fishermen set up fish houses and
fished all night. Many were observed coming in at 4:00 am and staying though -out
the day. There were never any DNR checks and controls. We believe that the lake
might have been fished out so we restocked Bass fingerlings in 1997. Bass Lake
Improvement Association would like to hire someone to do a new fish survey but the
DNR has implied that no one can do a survey except the state.
Trophic State and Water Quality
Bass Lake Improvement Association has trained volunteers taking weekly
readings. Please consult us and give us credit in any City reports.
Page 202 — Bass Lake Improvement Association (BLIA)would like the City of
Plymouth to note its increased efforts to submit monitoring data. We have many
records as trained volunteers and Montgomery Watson did not access our records.
They used only old DNR data. Also, BLIA is considering Alum treatment in the
near future. We have harvested and treated this lake chemically at our expense since
1970. We agree with the "Treatment Potential" statements wholeheartedly.

Page 202 — "Lake Atlas" We no longer have the large populations of Bullhead etc.
We have stocked Pike and Bass. Give credit to Bass Lake Improvement Association
for the stocking. Bass Lake needs to be surveyed by the state or professional
surveyors. The DNR told us that what we catch is indicative of what is in the lake. If
that is the case, pike, bass, crappie, sunfish are in high quantities.
Page 202 — Please explain why the in -lake ranking, though high in comparison to all
Plymouth lakes, is considered poorer than four of the City's eight major lakes. Is it
based only on the fact that we have no DNR access? Be careful which analysis you
are using and beware the criteria. The data used is several years old. The
Montgomery Watson report used old DNR data. Now the City of Plymouth is using
old data. Some of this information is 20 years old according to the records kept by
Bass Lake Improvement Association. WHERE IS FIGURE 44 LAKE ATLAS?
Page 203 "Prioritization of Improvements " - BLIA is in agreement that SC22 needs
storm water treatment, perhaps a catch basin after the water runs down from the hill
areas and before it enters the cattail wetland labeled as high priority. We should not
ruin this wetland with direct runoff. SC35 and SC36 need catch basins at some point
to clear the water before it reaches Bass Lake. It looks like SC27 would be a good
candidate for a grit chamber at the lake's edge.
Page 207 — We question the City Ranking ... Is DNR large boat access part of the
equation? What about over -all aesthetics? How are the individual categories (page 3)
ranked and weighted? Who ranked and weighted the categories? Can these Rankings
be discussed? We have a large acreage City of Plymouth Park that Bass Lake
Association was instrumental in developing. Why isn't this park/lake considered as
important as Medicine and Parkers Lake. Is it because the State and County are not
involved? Who created the Rankings?
Page 207 BLIA would like to help get in -lake component nutrient loading
information. BLIA would like to study HARVESTING to reduce internal nutrient
loading. We also want to have a point site monitoring study done.
Page 207 — Fishery is NOT out of balance. BLIA has been stocking Bass and
Northern Pike for several years. DNR data is old. A new study should have been
done in 1996 but was not done due to financial/manpower constraints in the DNR
according to one DNR officer. BLIA would like to have our activities on record as
much as the DNR, Hennepin Parks, and City of Plymouth activities are on record.
Page 207 - Add: Implement a City -Wide plan to sweep the streets before the spring
rains wash the winter sand, automobile chemicals and trash into the area wetlands and
lakes... specifically Bass Lake. Perhaps the lake areas could be swept in February or
early March rather than waiting for the very last snowstorm in March or April.

Page 207 — Add: Implement an EDUCATION CAMPAIGN in the watershed area to
educate Shingle Creek Watershed homeowners.
Page 208 - Point 2 Prepare feasibility study regarding storm water treatment options:
Under Resources: ADD: Lake Association. We would like to be involved in the
planning of grit chambers, changes to pond areas and the addition of lengths of pipe
which might eliminate natural means of nutrient cleansing of storm water.
Page 208 BLIA totally agrees that a new fish survey needs to be done to add to the
existing OLD data. We would invite the City to help us find someone to do the
survey. BLIA already has incorporated a fishery plan and has regularly stocked Bass
Lake with Northern Pike and Bass fingerlings. The latest Bass fingerling stock was
added in 1996. Our long time volunteer, Walter Richards has kept complete records.
