I. CALL MEETING TO ORDER—MAYOR JEAN HARRIS
Mayor Harris called the meeting to order at 5:50 p.m.
H. APPROVAL OF AGENDA
M. LAKE WATER QUALITY DISCUSSION
Perry Forster, Chair of the Riley-Purgatory-Bluff Creek Watershed District, presented a
report on the District. The RPBCWD covers approximately 65 square miles, with 11
lakes and 3 creek basins.
Funding sources are:
• Administrative Levy: $200,000/year(fixed)
• Basic Water Management Levy: approximately $500,000/year (changes based on
assessed valuation)
• 509 Levy: $300,000 (can vary depending on tasks to be undertaken)
• Stream Water Maintenance and Repair Levy: $15,000/year(fined)
The administrative budget does not contain any contingency money. The controversy
over damage to the cranberry bog in the Bearpath community has been very costly for the
Watershed District. However, the buffer will soon be put in place, and the District hopes
to recover some of its costs.

The programs undertaken by the Watershed District are:
(1) To issue permits for any projects having more than one acre. Projects are
reviewed for minimizing impacts on water resources, flood protection and water
quality.
(2) To collect data on water quality. They have collected data on an annual basis for
both streams and lakes since 1971. The data are summarized on reports sent
yearly to the city.
The Watershed District's Water Management Plan was summarized. It focused on water
resource integrity and beneficial uses. Use Attainability Analyses (UAAs) for lakes and
streams seek ways to obtain/maintain optimal water-quality conditions and to achieve
beneficial uses. UAAs will result in cooperative projects involving the Watershed
District and its constituent cities and/or other agencies to resolve water quality problems.
District rules and regulations pertaining to storm runoff management may change to
prevent stream channel degradation, and to protect habitat structure for aquatic biota
(e.g., detention basin design criteria and "rainwater gardens"). The Plan anticipates the
requirements of U.S. EPA/MPCA Phase 2 NPDES stormwater permitting program.
Mr. Forster explained that "rainwater gardens" hold pollution at the source. They are
placed in a swale adjacent to a road, with prairie plantings to hold the water. Rainwater
gardens are controversial because cities wonder if their physical integrity will stand up
over a long period of time. They are used in combination with detention ponds.
The second generation Water Management Plan was also explained. It builds upon
historical flood-control efforts, places new emphasis on the ecological integrity of lakes
and streams and sets beneficial-use goals for all water bodies.
Lake UAAs determine the current and historic water quality conditions, set beneficial use
goals, assess attainment or nonattainment for current watershed land-use conditions, and
if nonattainment is predicted for ultimate development conditions, recommend feasible
alternative remedial measures. Stream UAAs considers current and potential future
conditions and physical conditions described according to Rosgen Stream Classification
and habitat evaluated according to the Wisconsin Classification of Physical Integrity for
Streams rating procedure. Barringer said Purgatory Creek was a trout stream at one time
but the rise in water temperature caused by pollutants eliminated trout.
The work schedule for monitoring and use attainability analyses of lakes was reviewed.
A report is expected by mid-summer, Forster said. A meeting was held with City Staff a
month ago to go over the proposed rules and to hear objections, questions and comments.
The goal is to try to stop what is happening in terms of erosion and degradation of lakes
and streams and take them back to where they used to be 30-40 years ago.
Lambert said he encouraged Bob Obermeyer to set up this meeting to discuss the
different roles of the Watershed District and the City with regard to the study on Round
Lake, and where they are in their separate processes. A method has been suggested for
continuing the use of Round Lake as a swimming beach while addressing the various
issues, including goose management, etc.

Dietz said everyone there had the same agenda. The Watershed District has finished its
Water Management Plan and has a process to implement that plan. Up to this time, the
City has not had a chance to be included. The next step is a two-year process to do Eden
Prairie's Water Management Plan with the help of a consultant. To make sure the City's
goals are consistent with those of the Watershed District's, the City's plan has to be
brought to the Board of Water and Soil Resources (BOWSR) and the Watershed District
for approval. The City needs to know what the choices may be in order for that to be
accomplished.
Forster said the City first has to get BOWSR's approval of its Water Management Plan.
The Watershed District's plan had to be redone after BOWSR saw it, requiring them to
change the way they thought about some things. Forster suggested getting people from
the RPBCWD citizen advisory committee involved. He invited the City to look at water-
quality data the District has collected. Leslie Stovring replied that City Staff has been
actively involved with the citizen advisory committee and she has talked to Bob
Obermeyer. Dietz said the City does utilize the data the Watershed District has on water
quality.
Forster said the lakes in the Watershed District are interconnected all the way to
Chanhassen. That means it is necessary to work from where the pollution starts all the
way to the end. The idea of retention ponds and rainwater gardens came from the desire
to contain pollution where it starts.
Butcher asked if there is any urgency to completing the Water Management Plan. Forster
responded that federal and state agencies say they have to be in place within two years.
There are also certain mandates coming from the EPA in 2003, which will change the
way water is managed. The Watershed District has been taking a pro-active approach.
The objective is to present various options and alternatives as to what can be done to
improve water quality in the District. To maintain the integrity of Riley Lake and Round
Lake, decisions will have to be made, such as whether citizens want to spend money to
improve the lakes. The purpose of the Use Attainability Analysis is to lay out what it will
take to improve those lakes.
Butcher asked if funding is available at the state level for lake improvement. Bob
Obermeyer replied that the Use Attainability Analysis gives an opportunity for cities to
petition the Watershed District for money to undertake these improvement projects.
Money is available to fluid its portion of a project through the taxes it receives from the
cities. If the City wanted to petition the District for work on Round Lake,the District can
fund it for 16 consecutive years. However, other cities are also petitioning for funds.
Butcher asked where other cities are in completing UAAs, and was told they are at about
the same point as Eden Prairie. Bob Obermeyer has that information. Butcher said all
cities in the RPBC Watershed District benefit when improvements are made, because of
the way the lakes are interconnected.
Dietz said he didn't know if there are any federal funds available to cities, but Eden
Prairie has money in the stormwater utility fund. The first thing to do is determine a
priority of actions to take and think through the process for protecting against the access

of pollution, and then decide how to improve the water quality of the lakes. When citizen
surveys were done, water quality was near the top of the list. The City was waiting for
the Watershed District's 509 plan to get through the Bowser process, so did not start on
its Water Management Plan.
Forster said Eden Prairie has to get agreement with the other cities in terms of increasing
the number of retention ponds and rain gardens. That will make it easier later on. He
also recommended charging for field inspections and finding other sources for funding
lake improvement.
Mayor Harris asked what is the status of Riley Lake. Forster replied he believed the lake
quality to be much improved. There are a lot of fish living in it, mainly walleye and
northern pike. He recommended alternative ways of doing shoreline management, such
as not having lawn running all the way to the shore. It is a high-use lake with a lot of
water skiing.
Enger said ten years ago when the MUSA line was extended around Riley Lake the Met
Council thought the lake was ruined. Forster said the development of Bearpath and the
golf course helped stop pollution on the lake. Otherwise the development would have
been denser than it is, causing more pollution.
Enger said the crux of the land-use issue is that lower-density, single-family houses are
better because not as much impervious surface is created. Forster said with either high-
density or low-density housing, the goal should be to limit the amount of impervious
surface. The City needs to be vigilant and monitor what is happening.
Mayor Harris thanked the representatives of the Watershed District for coming, and
Forster thanked Council and Staff for inviting them.
