SUBJ: Surface Water Management Plan (SWMP) Second Reading
There was a delay in the second reading for the S?VMP because City Attorney Roger Knutson
noticed some errors in the text. The text has etz corrected and the changes to the document
are noted below and on the attached pages In` the process, it came to staffs attention that the
font of the document was not compatible with'the Ci computer system. As a result, staff will
be requesting Bonestroo to reprint the 75 copies of tle SWMP in Times New Roman, the font
used by the City. The City will maintain ' °mailing listf those who have a SWMP so that they
can be informed of updates in the futurpa' 1'rz

3. The text and appendix G discussing the process in which the City determined the
recommended fees for the SWMP trunk rates was deleted. This information is available,
but it did not make sense to put it in the report. It is part of the research and work put
into the report and the report should just contain the conclusions, otherwise it becomes
' bulky.
B. Text Ermis
There were a number of places in Chapter IV - System Description that gave the wrong location
for some of the City's lakes. For example, they would say Hennepin County for lakes located
' in Carver County. Chanhassen Township was also used in many of the location descriptions.
The county locations were corrected and Chanhassen Township was deleted.
' C. Legal Descriptions
I 1. In a couple places, the state rules or regulations associated with the plan were better
defined (i.e. Chapter 8410 of the Minnesota Rules rather than Chapter 509).
2. The City is designated as the local government unit under the Wetland Conservation Act
by the legislature, not by the Board of Water and Soil Resources.
3. The text associated with permit programs in Section I - C Regulating Watershed
Organizations was removed in order to avoid confusion of the rules associated with
watershed districts. This City will pursue the process of having the plan approved by the
' governing watershed organizations and will then assume responsibilities associated with
it.
1 2. ORDINANCES IN SWMP
Ordinance 202 concerning wetland protection and Ordinance 217 adopting the new shoreland
' management regulations will be inserted into the SWMP.
' 3. AMENDMENTS TO CITY ORDINANCES
With the adoption of the SWMP, there will have to be a City Code Amendment to Chapters 18
' and 20. The amendment to Chapter 18 (Subdivision Ordinance) is attached and can be adopted
at the October 24, 1994 City Council meeting. The amendment to Chapter 20 (Zoning
Ordinance) will require a public hearing. The formal process to amend this ordinance will begin
' soon after the SWMP is adopted.

4. FEE RESOLUTIONS
Since the SWMP has documented the connection charges associated with stormwater quality and
quantity, a fee resolution is not necessary. In the future, when the fees are modified in
accordance with the SWMP, a fee resolution from the City Council will be necessary. The
following information will be used to determine connection charges for new plats.
Water Quality
The SWMP has established a connection charge for water quality systems. The cash dedication
will be equal to the cost of land and pond volume needed for treatment of the phosphorus load
leaving the site. The requirement for cash in lieu of land and pond construction shall be based
upon a schedule in accordance with the prescribed land use zoning. Values are calculated using
the market values of land in the City of Chanhassen plus a value of $2.50 per cubic yard for
excavation of the pond if the applicant constructs the pond or $4.00 per cubic yard for excavation
of the pond if the City constructs the pond. The market value for land is based on the following
table:
Land Use
Cost/Acm ($)
Single Family
18,000
Duplex
21,000
Town Home
24,000
Schools, Churches
23,000
Apartment
27,000
Industrial
43,560
Commercial
130,680
Fees are reduced based on the costs of the developers contribution to the SWMP design
parameters. The market value of land and the construction costs for the excavation of material
should be reviewed and updated annually by the City Council.
Water Quantity
The SWMP has established a connection charge for different land uses based on an average, city-
wide rate for the installation of water quantity systems. This cost includes all proposed SWMP
trunk systems, culverts, and open channels and stormwater ponding areas for temporary runoff

storage. The connection charge is based on the type of land use for the area. Fees will be based
on the total developable land. Undevelopable area (wetlands), public parks, and existing
development is exempt from the fees. The fees are negotiable based on the developers
contribution to the SWMP design parameters. The following table is the fee structure for water
quantity connection charges:

The trunk storm sewer system and the cost of constructing storm sewer should be reviewed and
updated annually by the City Council.
Cost for purchasing SWMP manual or individual maps
Staff recommends approval of the attached fee resolution establishing the cost of the SWMP and
associated maps for those groups interested in purchasing them. These figures were based on a
rough estimate for administration and duplicating the document or maps. Governmental agencies
and consultants working for the City will not be required to purchase the document.

Executive Summary
This report presents the Comprehensive Surface Water Management Plan (SWMP) for the City
of Chanhassen that incorporates all three surface water elements: stormwater quantity, '
stormwater quality, and wetlands and lakes. The integration of the three distinct elements in the
overall plan is done in balance and harmony with each other and in conformation with the '
specific Agency requirements regulating each particular element.
The Chanhassen's SWMP puts special emphasis on preserving and enhancing DNR protected '
wetlands. All DNR protected wetlands have been classified as Natural Wetlands within the
City's classification system. '
The Chanhassen's SWMP satisfies the watershed requirements for local plans as stipulated ,
by hapter 8410 of the Minnesota Rules The Chanhassen's SWMP also satisfies the
Metropolitan ouncil's initiative to protect water quality in the Minnesota Basin, and it is
consistent with the 19% State of Minnesota Wetland Conservation Act. '
The general objectives of the Chanhassen's SWMP are summarized as follows: '
• To plan for future development and growth and reduce to the greatest practical
extent the public capital expenditures necessary to control excessive volumes
and rates of runoff.
• To minimize flooding, erosion and sedimentation from surface flows.
• To improve stormwater quality in all protected waterbodies and lakes.
• To preserve and enhance wetlands. '
• To protect and enhance fish and wildlife habitat. I
Executive Summary i
I. Introduction
I -A Background
1
The purpose of this report is to provide the City of Chanhassen with a Surface Water
Management Plan (SWMP). The City has been experiencing a significant amount of
development in the last five years and expects to continue and increase in the future. As areas
' develop from rural to urban, runoff increases and so does the need to convey it. Runoff carries
nutrients and pollutants associated with urban practices which impact the City's wetlands, creeks
and lakes. This SWMP will serve the City as a tool to protect, preserve and enhance its water
resources. The plan identifies from a regional perspective the stormwater quantity and quality
improvements necessary to allow future development to take place and minimize its impact to
' downstream waterbodies.
T"theState ocal Government Unit (LGU)�as designated under the Wetland Conservation
Ature with the authority to manage and regulate its water resources within the
mate and Federal law. The City's responsibilities as a LGU concentrat e on three
eQuantity ontrol, Water Quality Standards and Wetland Conservation. This
plan was developed around those three elements and is divided in two parts. Part I (Water
' Resources Management) deals with Water Resources Management issues while Part II (System
Analysis) deals with the technical issues associated with the protection of the City's water
' resources.
The City has assumed a proactive role by naming a SWMP Task Force which has served as a
guide of the plan's effort and also concentrated on implementing a Wetland Protection Ordinance
(adopted by the City Council in December, 1992), a Best Management Erosion Control Handbook
(adopted by the City Council in October, 1992) and a public education program. The City has
also proposed a first draft of the Shoreland Management Ordinances (December, 1993) currently
' being reviewed by the correspondent agencies. A copy of these ordinances can be found in
Appendix A. The task force, after receiving the first findings of the plan, requested the City
Council to approve some improvements to protect Lotus Lake which is showing the effects of
a highly urbanized watershed. This SWMP also includes an improvements financing section.
I
Introduction I -1
t
Proposed regional improvements associated with future development will be financed by future �
development. Cash contributions and in -kind contributions are two of the financing options
studied in this plan. ,
The City of Chanhassen is located in the southwestern portion of the Metropolitan area in Carver
County, as shown in Figure I -A 1. Chanhassen is bordered by: '
• Shorewood to the north; '
• Eden Prairie to the east;
• Shakopee to the south; '
• Chaska and Victoria to the west. I Loan r �, /in.e-3 r� rno✓2G� on VVJJ.�-SAJ GlrSfrlCf RGU1LJ
I -B Task Force Goals
The Chanhassen Surface Water Management Task Force was formed at the outset of the planning
process (August, 1991) and has closely followed the development of the plan through regularly
scheduled meetings. The Task Force is made up of members of the City Council, the Planning '
Commission, the City Staff, and representatives of the citizens of Chanhassen.
The purpose of the Task Force is to provide guidance to the City in formulating the goals and '
policies that will result in the successful implementation of the Surface Water Management Plan.

I -C Regulating Watershed Organizations
The City of Chanhassen is located within the boundaries of four watershed organizations.
' Minnehaha Creek Watershed District
• Riley - Purgatory - Bluff Creek Watershed District
• Lower Minnesota River Watershed District
' Hazeltine - Bavaria Watershed Management Organization
The Chanhassen SWMP is consistent with these Watershed Organization Plans and BWSR
requirements and serves as a guideline for the City to manage and regulate its water resources
as an LGU within the mandates of the State and Federal law.
I -C.1 Minnehaha Creek Watershed District
The Minnehaha Creek Watershed District (MCWD) has prepared a Water Resources Management
Plan dated June 1993 in accordance with the Metropolitan Surface Water Management Act,
' Minnesota Statutes Chapter 103B.201 -255, Laws of 1982, Chapter 509. The MCWD plan has
been approved by the Minnesota Board of Water and Soil Resources (BOWSR). The plan
encourages local units of government to develop Surface Water Management Plans within two
years of the MCWD plan approval. The City will submit the SWMP to the MWCD for approval
by the MCWD Board of Managers. E I i '1e s •- �•�.n��.]

II -A Summary and Recommendations
ILA -1 Summary
The main purpose of the stormwater quantity portion of the Chanhassen Surface Water
' Management Plan is to serve as a guide for the expansion of the storm drainage system. The
storm drainage system map is shown on Figures 3 and 4, at the back of Part II - System
Analysis. The following issues have been incorporated into the stormwater quantity element of
this plan:
' Division of the City into major drainage districts and subdistricts based on contour maps,
grading plans and natural topography.
• Determination of stormwater runoff under ultimate anticipated land use conditions.
' General layout and sizing of trunk storm sewers and open channels.
i • Tributary areas, storage volumes, high water levels and peak outflows of all required
ponding areas.
• Incorporation of existing wetlands into the storm drainage system.
• Estimation of construction and implementation costs of the proposed storm drainage
system.
• Estimation of per - district and City -wide connection charges to . y for the construction
' and implementation of the proposed st rm *ainage- system.
The primary function of an urban storm drainage system is to minimize economic loss and
inconvenience due to periodic flooding of streets and other low -lying areas. Adequately designed

report to ensure the successful operation of the storm drainage system.
• An equitable financing program for construction of storm drainage facilities be ,

established. This will insure that all areas in the City contributing to runoff pay their '
share of the cost of the stormwater system.
More specific recommendations dealing with existing flooding problems or priority improvements
for each watershed are proposed in the "Surface Water System Descriptions" Chapter in Part II - '
System Analysis.
II -B Goals and Policies
1
The SWMP's goal with regard to flood protection in the City of Chanhassen is listed below:
Goal: To provide 100 -year flood protection for all persons and property
The specific set of policies used in this report that served as the basis to achieve flood protection
are presented in Appendix F of Part I - Water Resources Management. '
II -C Cost Analysis I
Two of the main goals of the Chanhassen's SWMP are the determination of the total cost of the '
trunk system and the establishment of equitable trunk F — onnection charges ased on this total cost.
Cost estimates presented in this report are based on 1993 construction costs and can be related '
to the value of the ENR Index for Construction Costs of 5,230 (August, 1993). Future changes
in this index are expected and will result in future cost changes in the proposed facilities. During '
interim periods between evaluation of projected costs, capital recovery procedures can be related
to this index. The general locations shown on Figures 3 and 4 of the storm drainage facilities I
served as a basis for the cost estimate.
H4 Stormwater Quantity
' A summary of trunk costs estimates and excavation costs are presented in Table II -C1. Total
costs include construction costs and engineering, interest, administration and contingency costs.
' More detailed cost estimates are presented in Appendices B and C. Easement and land
acquisition costs are not included.
All lateral sewers will be installed as development occurs and paid f66 connection charge
to the developing property. All pipes which serve as connections between ponds or as outfall
sewers from ponding areas and all sewers greater than or equal to 24 inches are considered trunk
storm sewer facilities.
The SWMP recommends that all future developments be charged with .a connection c4or the
trunk area to pay for the overall trunk sewer costs. The charge would be based on the total cost
of the trunk system in the City and will be different for different land uses. The rates used for
connection charges on benefited land each year are adjusted each succeeding year to reflect
' current construction costs.
When development occurs in an area, it is anticipated that all ponding area easements for the
trunk system required within the area will be dedicated as part of the development. Occasionally,
early acquisition of various upstream and downstream ponding areas in undeveloped land is
necessary to accommodate the particular development. This acquisition must be carried out if
the system is to function effectively and prevent future flooding. The responsibility for the
acquisition must be addressed during consideration of the developments approval process.
In some cases, development will occur in areas where the trunk storm sewer system has not yet
been constructed. In these cases, the portion of the trunk system necessary in the development
should be constructed at the time of development. In all cases, the full trunk storm sewer area
Eonnection feeshould be charged to the developer through the development agreement, which
will enable the City to install the trunk storm sewer improvements shown in this plan to serve
this development without creating a need for charging future property owners within the
development.
I The trunk storm sewers stem and the cost of constructing storm sewer should be reviewed each
Y g
year. New rates should be established to reflect the change in cost of the storm sewer
construction each year and the Trunk Storm Sewer Fund should be examined to determine its
balance available for future construction. At intervals no greater than five to seven years, the
Stormwater uanti 11 -5
Q tY
storm sewer system that remains to be built should be re- evaluated and the cost of the system ,
re- estimated and compared against the amount of area still available for .
Storm drainage system total costs per acre are presented in Table II - C1. s '
per acre vary for each land use type as a function of the total volume of runoff generated at each
land use and the peak runoff flow. In this manner, developments that contribute the most runoff ,
will pay the highest rate as shown in Table II -C1. The6nnection chargearea in the drainage
districts in this report excludes all lakes, proposed ponds, floodplains and any other '
undevelopable land like wetlands or natural parks.

II -D Financing I
H -D.1 LConnection Rate Alternatives on New Plat I
The total storm drainage cost shown in Table H -Cl represents the cost of the water quantity '
element of the SWMP. This cost includes all culverts and open channels as proposed in the
System Layout Map (Figure 3), and stormwater ponding areas for temporary runoff storage. The
proposed system could be financed through a new trunk fund managed by the City. For each
new development, the City would collect the rates shown in Table H -Cl. That money would go
to the trunk fund and the city would be ultimately responsible for the construction of the storm ,
sewer system using trunk fund money. Developers are still responsible for the construction of
the lateral pipes to be connected to the trunk system. Also, developers that would up -size their ,
laterals to help the City's trunk system, or would build part of the system inside the development,
would be credited by the city against the trunkrconnection charge owed by the development.
Similar credits could be applied when stormwater ponding work consistent with the SWMP, is
performed by the developer within the development itself or in some other area of the city.
The City of Chanhassen can finance the storm drainage systems in four different ways as shown
in Table II-Cl: '
a) Using different & charges for different land uses and for each one of the
stormwater districts in the City.
b) Using an average, city-wide connection charge for each different land use.
c) Using a flat, per- acre[Connection charg]for each stormwater district.
d) Using a flat, per -acrCc nnection charge for the whole city.
It is our recommendation to use alternative b) as the financing option for the trunk fund. ,
Alternative a) would potentially involve 56 different rates and rates for the same land use would
vary a lot with district development. This would make it unfair for developers trying to develop
inside fairly developed districts who would have to pay a higher trunk rate than developers
building in less development districts. Alternative d), on the other hand, uses only one single
H -8 Stormwater Quantity
flat rate for the whole city and oversimplifies the problem by not accounting for the differences
in peak flows and runoff volumes generated by different land uses. Alternative c) emphasizes
development against land use and penalizes the residential areas of districts with a higher
percentage of CommercialAndustrial or high density development. Alternative b) provides an
equitable way to charge a connection fee for new plats under a city -wide approach.

II -D.3 Financing of Improvements on Existing Property
Stormwater quantity improvements in developed areas in Chanhassen could be financed through
any combination of the following financial sources:
• The existing stormwater utility fund
• A new storm sewer improvement district tax
Stormwater Quantity 11 -9
• A new storm sewer improvement district tax I
• Special assessments
•Connection Charges
The City of Chanhassen adopted a stormwater utility fund in the year 1990 that could be partially
used for water quantity improvements in existing developments. '
Financing stormwater improvements in developed areas through special assessments could
potentially be very difficult to accomplish. Under MN Statute Chapter 429 on assessment
procedures, any assessment amount on a property is limited to the increase in market value of
the assessed property. In other words, the local government has to demonstrate to the property
owner that as a direct result of the proposed improvements, the property market value will be
increased by the assessed amount. This may be difficult to prove for storm sewer improvements, 1
especially for runoff contributing property far from the problem area. The existing stormwater
utility fund, on the other hand, may be used to fund stormwater improvements throughout the I
City without the need to prove specific benefit.
An alternative method of financing stormwater quantity related projects on existing developments ,
may be the creation of a storm sewer improvement District tax. Under MN Statute Chapter
103B.245, local governments are allowed special taxing authority within a City area for storm '
sewer improvements. This could be used in combination with special assessments as long as all
of the rules under Chapter 429 are met. I

III -F Financing Alternatives
The total cost shown on Table III -El represents the cost of the water quality element of the SWMP.
The cost of stormwater quality improvements in future developments would be financed by the
developers through enforcing the water uality r uirements contained in this Management Plan
(Chapter IV of Part I "Requirements for New Plats "). The City will be in charge of enforcing these
requirements for each new plat.
Proposed water quality improvements in already developed areas or inside undevelopable land would
require additional funding assistance as suggested in Table VII-A1. The City of Chanhassen should
explore available sources of funding, like the stormwater utility fund, general fund, or special
assessments, when constructing those improvements.
The following is a discussion of some State and local programs which are available to assist in water
quality management efforts.
State
Clean Water Partnership Program (CWP): This program is administered by the Minnesota
Pollution Control Agency. Its primary focus is to mitigate the impacts of nonpoint pollution on water
quality. Fifty percent matching funds are available for diagnostic /feasibility studies and watershed
management projects. This program should be used when the causes of substandard quality in a
given waterbody are unknown. Funds from this program can be used to improve or construct nutrient
1 detention basins when these basins will improve the quality of recreational waterbodies.
Shoreline, Lakeshore and Roadside (SLR) Erosion Control Program: This program is
administered by the Minnesota Board of Water and Soil Resources. It provides fifty percent funding
for projects which control the erosion of lake shorelines or drainage systems leading into waterbodies.
t
Stormwater Quality III -9
Federal
Clean Lakes Program: This is a federal program administered by the Environmental Protection
Agency. The main focus of this program is to improve the water quality of lakes through in -lake
management practices (aeration systems, sediment treatments, dredging, etc.) or watershed
practices. Funds are available for both diagnostic /feasibility studies and the implementation of
improvement programs.
State
Clean Water Partnership Program (CWP): This program is administered by the Minnesota

when the causes of substandard quality in a given waterbody are unknown. Funds from this
program can be used to improve or construct nutrient detention basins when these basins will
improve the quality of Chanhassen lakes.
Cooperative Opportunities for Resource Enhancement: This program is administered by the
Minnesota Department of Natural Resources. The main focus of the program is to improve
fishery in lakes and improve access to lakes. This program can be valuable for obtaining
financial assistance for aeration systems, fish reclamation projects, fishing piers, and boat
launches. In instances where nutrient reductions are not economically feasible, water quality can
be improved to meet Secchi Disc criteria by biomanipulation (fish reclamation).
Shoreline, Lakeshore and Roadside (SLR) Erosion Control Program: This program is
administered by the Minnesota Board of Water and Soil Resources. This program provides 50%
funding for projects which control the erosion of lake shorelines or drainage systems leading into
waterbodies.

VI. Requirements for New Plats
VI -A General
VI -A.1 Premise
The land use change from undeveloped or agricultural to urban causes an increase in
nutrient load to Chanhassen's waterbodies. In addition, the expansion of the storm
sewer system delivers pollutants from increasing impervious surfaces and
housekeeping practices associated with the land use changes. Inappropriate erosion
control practices and construction waste management accelerates sedimentation and
pollution of wetlands, streams, and lakes.
To minimize the expenditure of public funds used to correct damages and deficiencies,
the City has published an Erosion and Sediment Control Handbook. (Copies of the
handbook are available by calling 937 - 1900.)
l
VI -A.2 Goal and Position
The City of Chanhassen recognizes it is essential to promote, preserve, and enhance
the quality of the city's water resources, and to protect those resources from adverse
effects caused by changes in land use. To promote water quality in the city, the
' requirements of Few plats re intended to promote the reduction of phosphorus loading
to the city's water bodies and minimize the need for future lake, wetland, and creek
restoration programs.
To minimize the impacts of pollution on Chanhassen's water bodies, those who
propose future developments will be responsible for reducing or maintaining
phosphorus export to undeveloped conditions resulting from a change in land use. On-
site treatment of pollutants will be the primary measure to treat storm water. This
position is supported by Minnesota Statutes 462.358.
Requirements for New Developments VI -1
t
This section establishes the procedures by which development and subdivisions will
be reviewed, and thereby minimize environmental damage, and protect the residents
and the City of Chanhassen from incurring high maintenance and capital costs '
resulting from the need to correct water quality problems.
Three activities central to achieving this goal are; '
• erosion and sediment control, I
• post - development phosphorus control, and
• where appropriate, pre- existing conditions will be remediated. '
VI -B Erosion and Sediment Control
Every development whose subdivision and /or site plan is referred to the City Council
for review, is required to submit an erosion and sediment control plan.
The erosion and sediment control plan should include, but not be limited to, the
following information:
• The property boundary and lot lines
• Two foot contours extending 200 feet beyond the property lines. I
• A drainage plan of the site delineating the direction and rate storm water is ,
conveyed from the site. The drainage plan shall contain contour lines and
design specs showing drainage patterns, identifying the location of water
quality treatment ponds and locating areas in which storm water is expected to
collect.
• A delineation of all wetlands, waterbodies and water courses located on and
within 200 feet of the development noting the bottom normal and high water
levels.

VI -D Dedication Requirements
In accordance with Minnesota Statute 462.358, all new plats may be required to
dedicate land and construct a permanent detention facility for the purpose of treating
increased pollutants in the runoff as proposed in the SWMP. The size of the proposed
treatment facilities and their removal efficiency will depend on the required degree of
protection for the down stream wetlands and waterbodies.
An agreement to construct the required treatment basins or ponding areas and the
declaration of such property or easements shall be executed concurrent with the site
plan or plat approval.
Because of the regional character of the water quality improvements proposed in this
report, it is possible that no water quality ponding is shown inside a given
development. In this case, the City will request a cash contribution from the developer
to help the construction of the downstream pond that eventually will treat the
increased pollutants in the runoff from the development. The methodology to calculate
this cash dedication is explained in Section VI -D.2.
VI -D.1 Ponding and Land Dedication
Based on the regional water quality improvements proposed in this report, and the
specific circumstances of the development, the City may or may not require ponding
and land dedication in the development. If based on the results of the SWMP, the City
requires dedication of land, or easement for ponds and treatment basins, the surface
size of the pond, and other pond dimensions should be calculated using the Walker
design criteria. The necessary pond area will determine the land to be dedicated for
water quality ponding by the developer.
Any decision made by the City concerning ponding inkFnew plats will have to be
oriented towards keeping the desired level of protection in lakes and wetlands under
fully developed conditions. Interim phosphorus loads into potential lakes and wetlands
shall not exceed, under any circumstances, ultimate conditions levels.

VI -D.2 Cash Dedication `-
If on -site water quality treatment is not provided by the developer because it is not
feasible or it is not desired by the City, cash dedication may be required. Cash
dedication may also be required if the proposed water quality pond is not big enough
to satisfy phosphorus removal requirements.
The cash dedication, if utilized, will be equal to the cost of land and cost of building '
the wet volume needed for phosphorus removal at the site. The requirement, for cash
in lieu of land and pond construction, shall be based upon a schedule in accordance ,
with the prescribed land use zoning. Values are calculated using the market values of
land in the City of Chanhassen, plus a value of $2.50 per cubic yard for excavation of
the pond LNote: The fee for excavation may be changed from time to time by
resolution from the City Council)
J
Land values for cash equivalent contributions will be consistent with the following
rate schedule: I
1993 Rate Schedule For Cash Dedication *
Per Acre
Single Family $18,000
Duplex $21,000
Town Home $24,000
Schools, Churches $23,000 '
Apartment $27,000
Industrial $43,560 '
Commercial $130,680
These fees may be changed from time to time by resolution from the City
Council.
The cash dedication chart shown in Figure VI -D1 is intended to help estimate the
t
excavation cost and the land cost for typical types of development. Figure VI -D1
shows ranges for wet volume and pond area by using the curve number (CN) value and
size of the development. The CN value correlates to impervious areas as described in

The City may require cash even if it is determined by the City that there is additional
treatment capacity in an existing downstream treatment basin. To make it fair for all
developers in the City, no developer should be entitled to use an existing oversized
downstream treatment basin without contributing to the City's water quality fund.
VI -D.3 Mitigative Measures
In addition to the options of additional treatment basin construction, and cash
dedication, new plats may also be required to provide other mitigative measures if the
development results in an increase in the phosphorus export to downstream
waterbodies classified in the Chanhassen Stormwater Management Plan as lakes or
"Pristine" or "Natural" wetlands.
Other mitigative measures may include but not be limited to: reducing impervious
area, flow diversion, first flush treatment, or treatment of storm water discharge
through other means.

VII -A Summary of Financing Sources
The City of Chanhassen Surface Water System is a large and complex system. The SWMP
divides the City's surface water system into four elements: Water Quantity, Water Quality,
Wetlands and Lakes. Studies, improvements and specific action plans for each one of these
elements have been recommended throughout this report. A summary of the available sources
to finance improvements for the different elements of the plan is presented in Table VIE[-Al.

Water quantity improvements in already developed areas recommended in this plan may be
financed through the City's Storm Utility Fund, a new storm sewer improvement district tax, or
special assessments. All new water quantity facilities will be financed through the City's Trunk
Fund.
New water quality ponding will be financed through few plat connection charges.. Any water
quality improvements in already developed or undeve opa le areas may be financed through the
City's Stormwater Utility, General Funds, and Special Assessments, or through the State
Programs mentioned in Table VII -Al.
Wetland restoration and enhancement projects recommended in this report may be performed by
the developer as a requirement for final approval of the development plans by the City. The City
may also want to use the General Fund for specific wetland restoration and enhancement projects
with a City -wide impact.
Because of the potential use of Chanhassen lakes by all residents ofAe City, lake studies and
improvement programs could be financed through the General Fundipj other Federal and State
possible financial sources for lakes such as those listed in Table VII -A1.�
VII -B Water Quality Short -Term Strategy
The amount of solutions and actions that can be implemented to improve surface water quality
and enhance wetlands in Chanhassen are numerous. The short-term capital improvement plan
proposed in this chapter reflects the priorities defined in the SWMP for water quality, wetlands,
and lakes. This short-term plan also presents achievable goals based on an annual capital
improvements cost that can be easily financed once the SWMP is fully implemented. The
following is the list of proposed water quality improvements for the next five years:
• Initiate a monitoring and sampling program for lakes: Lotus, Minnewashta, Lucy, Ann,
Susan, Rice Marsh, Riley and St. Joe.
• Perform the first 10 highest priority lake management projects listed in Table V -D1.
• Construct 20 nutrient detention basins in existing and new developments using the City-
wide Sediment and Nutrient Trap Prioritization list of Table III -D1 as a guide for the
decision making process.
• Perform monitoring and sampling of wetlands along the fringe of Lotus Lake and Lake
Minnewashta to determine the phosphorus input to the lakes. Also, a monitoring and
sampling program should be implemented at key waterbodies in the Lotus and
Minnewashta districts to allow for water quality model calibration.
• Implement a public education program, as defined in Chapter IX, that will initially target
VII -2 Capital Improvement Program
to enter at this location. A high percentage of open water ponds in the District probably support
fish and invertebrate life.
IV -B.5 Lotus Lake
Lotus Lake is locatedu&er County, Minnesota, about 20 miles southwest of Minneapolis in
portions of sections 1 and 12 of Township 116N, Range 23 JV Within Chanhassen, the lake is
located on the northeast corner between Kerber Boulevard and State Highway 101.
Lotus Lake is approximately 240 acres in surface area and has a direct drainage area of 1062
acres. Lotus lake and its drainage area are shown in Figure IV -B 1. The watershed to lake ratio
is 4 to 1. The maximum and mean depths of the lake are 8.8 and 3.0 m, respectively. The
littoral zone (shoreline fringe area with depths of 0 to 10 feet which has the potential for lake
weed growth) covers about 74% of the lake area. The Lake has a 4.6 mile long shoreline. A
bathymetric map, furnished by the Minnesota Department of Natural Resources (MDNR) is
presented in Figure IV-B1 along with general characteristics of the lake.
The 1984 Lake Survey done by the MDNR indicates there are two inlets to Lotus Lake, one on
the south side and the other on the southwest side. Purgatory Creek is the principle outlet. All
three streams, including Purgatory Creek, have intermittent flows. The lake is considered a
"Priority Lake" in the Metropolitan Area due to its multiple recreational uses. The public access '
is located on the south end of the lake and is owned by the city. It is also accessible on the west
side of the northwest arm of the Lake where Township Road runs along the waters edge.

-� resulting in cooler temperatures, more protection from wind resulting in more humid conditions
and less evaporation and a shorter growing season due to later snowmelt and ice -out.
The wooded shorelines rovide an environment which is far different than cleared agricultural
P gn
fields. If the seed bank present has species best suited for wooded rather than open areas, it is
Rely that invasive species such as reed canary grass would have an advantage over the native
species in revegetating disturbed or stressed areas, especially when drainage is involved. In other
words, the plant species that were present originally may not be able to survive in the new
conditions. For the above mentioned reasons, along with the current seedbed being dominated
by reed canary grass, it may be necessary to establish a new seed bank in Agricultural/Urban
wetlands.
It is surprising that sedges were not observed as the dominant vegetation in Agricultural/Urban
wetlands since that is the species which is best suited to fill that niche.
Comprehensive restoration of these wetlands would require reforestation throughout the upland
areas. Given that this is not realistic in most cases, another option would be to revegetate the
wetlands with species that are best suited for the current conditions. Where possible it would
be desirable, to set aside buffer areas surrounding high quality wetlands and reforest the buffer
areas with native tree species.
This District has a high number of Natural wetlands which have a great diversity of plant species.
It is recommended that buffer zones and minimum setbacks be established around these Natural
wetlands as described in the City's ordinance.
I IV -C.5 Lake Minnewashta
Lake Minnewashta is located about three miles southwest of Excelsior in portions of sections 4,
5, and 8 of Lownship 116N, Range 239Within Chanhassen it is located in the northwestern
corner of the City, between Galpin Boulevard and State Highway 7.

IV -38 System Description
t
This pond possessed high water quality, including rooted submergent vegetation, tadpoles,
minnows, and a variety of aquatic insects. Dragonflies were abundant, including less common
species. A large diversity of plant species and wildlife was observed throughout this basin.
This District is along the southwestern fringe of the purple loosestrife invasion into the City.
Wetlands such as A2 -11(1) in the eastern part of the District are becoming dominated by this
invader. Control along the leading edge of the invasion will slow its spread. We recommend
control methods in accordance with the State's noxious weed control guidelines.
The Lake Lucy District is the headwaters for the Riley Creek watershed. Since this is a
relatively sizable drainage area, improvements made to wetlands in this District can benefit the
waters further downstream.
IV -D.5 Lake Lucy I
Lake Lucy is located in �xver County, Minnesota about 20 miles southwest of Minneapolis in
portions of sections 2, 3, 10 and 11 of — Ownship 116N, Range 23W. Within Chanhassen, the
lake is located in the north central area of the City, between Powers Boulevard and Galpin
Boulevard, north of Lake Ann.
Lake Lucy is approximately 86 acres in surface area and has a direct drainage area of 888 acres.
The Lake Lucy drainage area is shown in Figure IV-D1 along with other data on the lake. The
watershed to lake ratio is 10 to 1. It has a maximum and mean depth of 6.4 and 2.3 meters
respectively. The littoral zone (shoreline fringe area with water depth of 0 to 10 feet where
macrophytes grow) covers about 92 percent of the lake surface area. The Lake has a 2.6 mile
long shoreline. A bathymetric map, furnished by the Minnesota Department of Natural Resources
(MnDNR), is presented in Figure IV -D1. I
IV -60 System Description I
i
Since the Natural wetlands in this district are in wooded areas (other than those along the Lake
Ann shoreline), it is probable that A11 -6(1) has become Agricultural/Urban due to a change in
land usage from wooded banks to cleared farmland and possibly drainage. Much of the adjacent
upland is grassy old agricultural fields.
Impacts to these wetlands such as erosional sedimentation, nutrient enrichment, and changes in
the local environment (i.e. temperature and air moisture content), would be due to the clearing
of wooded areas and conversion to agricultural uses.
Observations and Comments: There are three small wetlands in the wooded area north and
northwest of the lake. One of these, A10 -4(5), is a high quality forested wetland vegetated by
green ash, mosses and sedge. Although not Pristine, this wetland is worth noting for future
protection.
In the eastern part of the District is a moderately large Agricultural/Urban reed canary grass
wetland (All- 6(1)). This would be a potentially good wetland for restoration since it has
degraded into a monotypic stand of reed canary grass. The recommendation for management of
this area would be to re- establish the hydrology and introduce a more diverse seed bank if
necessary.
The best wetlands in the district are along Lake Ann; A10 -4(2) on the north shore and A10 -12(1)
on the southwest end of the lake, at the outlet. It is recommended that these wetlands be
protected by following the buffer zone and minimum setback provisions of the City's Ordinance.
IV -E.5 Lake Ann
Lake Ann is located within a county park 1/2 mile west of downtown Chanhassen in portions of
sections 10 and 11 of�ownship 116N, Range 233W�. Within Chanhassen, the lake is located in
the north central section of the City, between State Highway 5 and Lake Lucy.
Lake Ann is approximately 120 acres in surface area and has a direct drainage area of 135 acres.
Lake Ann's drainage area along with general characteristics of the lake is shown in Figure IV-E1.
The watershed to lake ratio is approximately 1 to 1. The lake has a

onions of sections 13 and 14 of th Townshi 116N, Range 23W. Within Chanhassen the lake is
P � P
located in the central portion of the City, between State Highway 5 and County Road 18.
Lake Susan is approximately 88 acres in surface area and has a direct drainage area of 1178 acres.
The watershed to lake ratio is 13 to 1. It has a maximum and mean depth of 4.9 and 3.4 meters,
respectively. The littoral zone (shoreline fringe area with depths of 0 to 10 feet and where
macrophtes grow) covers about 1 percent of the lakes surface area. The lake has a 1.5 mile long
shoreline. A bathmetric map, furnished by the Minnesota Department of Natural Resources, is
presented in Figure IV -Fl along with general characteristics of the lake.
The 1983 lake survey done by the MnDNR indicates there are two streams which flow into Lake
Susan. The first flows from Lake Ann through the southern portion of Lake Susan Park. The other
flows from wetland A23 -3(1) on the southwest shore of the lake. There is one principle outlet which
flows to Rice Marsh Lake.
Its small size and limited public access reduces the use of the lake for boating. The lake is primarily
used by the residents for canoeing and aesthetic purposes. r
Lake Chemistry and Biology
Water Quality Indicators: The water clarity, total phosphorus, and chlorophyll-a trends for August
of 1971, 1975, 1978, 1981, 1984, 1988, 1990 can be seen in Figure IV -F2. Data indicate the water
quality has severe limitations for recreational uses.
According to the Metropolitan Council's rating of water quality for recreational use of lakes in the
Metropolitan area, Lake Susan has no significant recreational potential. The data shows that 1971
was the last time the lake was severely impaired, but usable for recreation. The Metropolitan
Council's ranking of water clarity indicates Lake Susan has very poor water clarity for most of the
years observed. The readings (total phosphorus, chlorophyll-a, secchi disc) do not meet the ecoregion
value standards for all the years studied except for 1971 and 1990.
System Description IV -99
-� Observations and Comments: Rice Lake Marsh appears to be important for waterfowl both
during migration (spring and fall) and during nesting season. Waterfowl were observed either
flying or swimming throughout the open -water season.
Protection of wetland A13-8(l) during the waterfowl courting and nesting season is
recommended. Persons walking on paths would not pose a problem. The appropriate restriction
would be for dogs and cats to be either confined or leashed during this period. A restriction on
dog training in the field at this location during this same period would also be recommended.
�. Since reed canary grass dominated wetlands are not common to this District, restoration potential
of this type of wetland is not as high as it is in other Districts. Improvements to
Agricultural/Urban wetlands within the District would be to establish upland buffer zones and
establish wetland vegetation best suited for the area as needed.

IV -G.5 Rice Marsh Lake
Rice Marsh Lake is located in Carver and Hennepin County, Minnesota, about 20 miles
To
sou est of Minneapolis, and is located predominately in Section 13 o wnship 116N, Range
23W. A portion of Rice Marsh Lake is located in Eden Prairie. Within Chanhassen, the lake
is located in the central eastern section of the City, between West 70th Street, Great Plains
Boulevard and Lake Riley.
Rice Marsh Lake is approximately 79 acres in surface area and has a direct drainage area of 813
acres. The watershed to lake ratio is 10 to 1. It has a maximum and mean depth of 3.0 and 1.5
meters, respectively. A bathymetric map, furnished by the Minnesota Department of Natural
Resources, is presented in Figure IV -G1 along with general characteristics of the lake.
Rice Marsh Lake receives flows from Lake Susan via Riley Creek which flows through wetland
A13 -8(1), and drains into Lake Riley by the same creek. The lake is used mainly

Chanhassen. In Chanhassen the lake is located between proposed State Highway 212 and Pioneer
Trail (County Road 14).
Lake Riley is approximately 295 acres in surface area and has a direct drainage area of 1,391
acres. Lake Riley's drainage area and general lake characteristics are shown in Figure IV -H1.
The watershed to lake ratio is 5 to 1. It has a maximum and mean depth of 15.2 and 7.6 meters
respectively. The littoral zone (shoreline fringe area with water depths of 0 to 10 feet where
macrophytes grow) covers about 3.7% of the lake area. The Lake has a 3.2 mile long shoreline.
A bathymetric map, furnished by the Minnesota Department of Natural Resources, is also
presented in Figure IV -H1.
The principle stream to Lake Riley is Riley Creek which enters in the northwest corner of the
lake and outlets in the southwest corner of the lake. The lake is considered a "Priority Lake" in
the area because of its multiple recreational uses. The dominant recreational uses are fishing,
boating, swimming, and waterskiing. In fact, heavy recreational use on the lake limits fishing
to early morning and late evening hours. A public boat access is located on the east central shore
of the lake and maintained by the City of Eden prairie. I

OF THE CHANHASSEN CITY CODE CONCERNING
SURFACE WATER MANAGEMENT
THE CITY COUNCIL OF THE CITY OF CHANHASSEN ORDAINS: I
SECTION 1 . Section 18 -63 of the Chanhassen City Code is amended to read:
18 -63. Surface Water Management.
(a) All subdivisions shall comply with the City's surface water management
plan dated February 1994, which is incorporated herein by this reference. '
(b) In accordance with the City's surface water management plan as a condition
of subdivision approval subdividers shall pay a water quality and water quantity
connection charge. The charge shall be based upon the gross area of the subdivision less
the area to be dedicated to the City for ponding, parks and wetland, and right -of -way for
state highways, county roads, and local arterial roadways. The subdivision will be given
a credit for any on -site storm water improvement which has been oversized to serve
property outside the subdivision. The charge for lots oversized due to individual on -site
sewage disposal and water systems will be reduced to the charge that would be imposed
on a one -half acre lot. An additional charge will then be imposed if the lot is further
subdivided less a credit for the charge previously paid. The charge shall be paid in cash
before the subdivision is approved by the City unless the City and subdivider agree that
the charge may be assessed against the property. Property being subdivided shall be
exempt from the water quality and water quantity connection charges imposed by this
section if the charges were paid or assessed in conjunction with a previous subdivision
of the property and if the property is not being zoned to a classification with a higher
charge.
