MINUTES OF THE LAKE ADVISORY COMMITTEE
September 21, 2004
I. CALL TO ORDER
The Lake Advisory Committee (LAC) Meeting was called to order at 6:00
P.M. Members present: Harry Alcorn, Dan O'Keefe, Brad Beneke, Donna
Mankowski and Marv Mirsch. Members absent: None
Others present: Jim Petersen; Council member, Jane Kansier; Planning
Director, Larry Poppler; Assistant City Engineer
II. CONSIDER APPROVAL MEETING MINUTES
Donna Mankowski made a motion to approve the January minutes seconded
by Marv Mirsch. The minutes were approved as written.
III. OLD BUSINESS
a. Update and Review of Dock Issues with Jane Kansier, Planning Director
Kansier distributed current ordinances on docks. This ordinance only
addresses the docks associated with associations. Kansier also
distributed the state rules on docks. The state rules address definitions
and commercial dock usage. The City's approach since the DNR has
relinquished it's dock authority is to use Minnesota Rules section
6115.0210 sub paragraph 4. The City-r~cently completed an ordinance
amendment for boat lifts and rail systems above the 904. When the City
receives phone calls on docks the City refers to the state rules. The City
receives around 50 phone calls on docks and they are typically received
early in the Spring. The DNR receives around the same number of phone
calls. The location of the docks comprise the majority of complaints or
questions. Around 1000 personal docks, 380 association slips, and 150
commercial slips are located on Prior Lake. Not all of the association
docks comply with the current ordinance as some associations were
created prior to the ordinance.
Mankowski asked about the regulation of a particular dock which does not
have an association.

Phone 952.447.4230 / Fax 952.447.4245
Kansier responded that this dock issue was not regulated as an
association dock.
Mirsch stated that the question is whether the City would like to establish
an ordinance to regulate the personal docks.
Alcorn asked whether 50 phone calls on 1000 docks warrant an
ordinance.
Petersen responded that the dock issue creates issues between
neighbors on small lake lots. Petersen stated that people have asked him
about some of these dock issues.
Kansier stated that a staffing commitment would be necessary if the City
were to draft an ordinance similar to the White Bear Lake ordinance.
O'Keefe stated that a permit wou~d be necessary for docks in order to
fund the staffing if we create an ordinance.
Beneke asked what if a homeowner were to dispute the dock location of
their neighbor today. What would happen?
Kansier answered that if the neighbor were in violation of a zoning
ordinance the City would act on it, if not the homeowner may have to take
the matter to a civil court.
Mankowski stated that when the water goes down they can expect to see
additional phone calls. She asked if it is possible to put some minimal
language in an ordinance to avoid some of these phone calls.
Kansier responded that the ordinance could be modified to include the
language from the state rule and clean it up with language about the
number of docks.
Mirsch added that language about placement of docks could be added to
the ordinance.
O'Keefe stated that common sense neecslO prevail in many of these
docks situations.
Mankowski added that there are so many different dock situations which
could occur.
Beneke stated that the recommendation from the LAC to the City Council
should be as follows:
The Lake Advisory Committee recommends that the City Council
consider the following in regards to docks:
a. There is not sufficient demand for an ordinance pertaining
to docks
2
b. The task of managing a dock ordinance is too complicated
based on the symmetry of the lake and lake lots.
c. The jurisdiction between. the below the 904 elevation is in
question.
Therefore the Lak.e Advisory Committee recommends that in
matters of dock di.sputes and questions the City should
continue to refer to Minnesota State Statutes and that no
ordinance be adopted pertaining to docks at this time.
The LAC approved the recommendation as stated by Beneke.
b. Boat Slip Policy
Pop pier stated that the City Council has asked the LAC to talk about and
give a recommendation regarding the 18 boat slips which are being
constructed at Watzl's Beach. The .issues include overnight policy,
reservations, hour limits on certain slips, and enforcement.
Mankowski stated that a reservation policy would be difficult to administer
and that the boat slips should be done on a first come first serve basis
and that the boats should be gone when the park closes. Mankowski also
stated that signage should be placed detailing the park hours and that no
overnight parking is allowed.
Alcorn stated that the sign should read that the City accepts no liability for
damage to the boat.
Mirsch stated that lighting should be placed near the dock area since the
park remains open when it is dark. Additional bouys may be needed
within the bay.
Alcorn asked if the dock does not have railings, is the City liable for
someone falling off the dock and drowning?
The Lake Advisory Committee recommends that the City Council
consider the following items when adopting the boat slip policy:
1. The boat slips should be utilized on a first come first
serve basis. No reservations should be taken for the
boat slips.
2. The boat slips should only be utilized during park
hours.
3. Signage should be placed outlining these policies as
well as stating that the City accepts no responsibility
for damaged or lost property during dock usage.
4. Lighting should be placed near the dock as the park
hours extend beyond daylight hours.
5. Additional buoys may be needed near the location of
the boat slips.

IV. NEW BUSINESS
a. LAC Meeting Frequency and Time
Pop pier stated many times this past year it has been difficult to f ill an
agenda for the LAC me~tings. The City is looking for feedback from the
LAC about how often this body should meet. The City is also looking for
feedback on the meeting time. Is 6:00 pm work for everyone?
The LAC agreed that the 6:00 pm time works well.
Alcorn suggested meeting quarterly.
O'Keefe stated that quarterly would be too drastic a change. The
meetings could be filled with educational items when no specific City
Council issues need to be addressed.
Mirsch mentioned that the Comprehensive Lake Management Plan
should be looked at for guidance on the meeting items.
O'Keefe stating that we need to get structured but need to continue to
meet monthly.
Poppler suggested that each meeting could focus on specific lake items
such as: Surface Water Regulations, Water Quality, Shoreline
Restoration, Other Groups 0 n the Lake, Capital Improvement Program,
Boat Tour and Development Standards.
O'Keefe stated that history and knowledge of the watershed of Prior Lake
should be part of the LAC's knowledge base.
Alcorn suggested that each member of the LAC should generate a list of
the people or organizations associated with the lake so that we can
contact them to invite them to the meetings.
O'Keefe stated that using the list of organizations associated with the
lake, the October meeting could focus Em setting up an agenda for the
year. Members should brainstorm ideasror meeting topics even if it is
knowledge based.
V. ANNOUNCEMENTS
a. E-Coli Year End Results - Poppler circulated the memo regarding the e-
coli for the summer of 2004.
b. Chloride Monitoring Results - Poppler included a memo created to
determine how the chloride levels relate to usage.
4
c. Shoreline Grant Application - Poppler stated that the Watershed District
and the City a re working together to receive a g rant from the D NR for
shoreline restoration.

or by all purchasers of non-riparian lots in the subdivision who are
provided riparian access rights on the access lots; and
d. Covenants or other equally effective legal instruments must be
developed and recorded that specify which lot owners have authority
to use the access lot and what activities are allowed. The activities
may include watercraft launching, loading, storing, beaching, mooring,
or docking. The covenants must also include other outdoor
recreational activities that do not significantly conflict with general
public use of the public water or the enjoyment of normal property
rights by adjacent property owners. Examples of the non-significant
conflict activities include swimming, sunbathing, or picnicking. The
covenants must limit the total number of watercraft allowed to be
securely moored, docked, or stored over water, and must require
centralization of all common facilities and activities in the most suitable
locations on the lot to minimize topographic and vegetation alteration.
The covenants must also require all parking areas, storage buildings,
and other facilities to be screened by vegetation or topography as
much as practical, from view from public water, assuming summer,
leaf-on conditions.

RE: Beach Testing Results
Watzl's Beach and Sand Point Beach were tested for E. Coli during the summer of2004.
E. Coli is generated from animal waste; so all water will have some level of bacteria. The
results of the tests showed low levels ofE. Coli. The results are as follows:

RE: Chloride Sampling Update
~ The sampling results including the mean chloride content are attached on the
following page.
Minnesota State Rule 7050.0222 assigns a quality standard for Class 2A
waters, which would include Prior Lake. The chronic standard for chloride in
Class 2A waters is 230 milligrams per liter. The "chronic standard" is the
highest water concentration of a toxicant to which organisms can be exposed
indefinitely without causing chronic toxicity. If the standard is exceeded, it is
considered indicative of a polluted condition which is actually or potentially
deleterious, harmful, detrimental, or injurious with respect to the designated
use.
A study done by MnDOT in 1994 lists an MPCA chloride standard for surface
waters as such:
High quality recreational waters (2A) = 50 mgll chloride
High quality industrial waters (3A) = 50 mg'l chloride
Good quality industrial waters (3B) = 100 mgll chloride
A five-year study conducted my MnDOT, which began in 1982, on 13 metro
area lakes that receive highway runoff resulted in a mean average of 88.3
ppm chloride content.

The Minnesota Pollution Control Agency prepared a report entitled
"Minnesota Lake Water Quality Assessment Data: 2000", published October
1999. Prior Lake is located in the North Central Hardwood Forests eco-
region. The summer average Chloride (mgll) content for non-urban lakes in
this region is 4-10 ppm.
CONCLUSION
,-
Reviewing the various standards and concentrations that have been
established, the mean for Prior Lake is a good level for a highly used metro
lake.
