1. The Permit (Part III.D.3.) requires that, within 12 months of the date permit coverage is extended, existing permittees revise
their current program as necessary, and continue to implement and enforce a program to detect and eliminate illicit
discharges into the small MS4. Describe your current program:
The City has Ordinance 854 - Storm Water Illicit Discharge and Illicit Connections, which prohibits illicit discharges or illicit
connections to the City storm sewer system. As part of this, 20% of outfalls are inspected annually for illicit discharges.
This IDDE program will be updated to meet new permit requirements of prioritizing areas and developing written
procedures for conducting IDDE inspections.
The City also maintains the sanitary sewer system by televising and jetting a certain portion of the system each year. The
televising process identifies any damage /defects the system may have, which are then repaired. The jetting of the sanitary
sewer system removes blockages which will prevent any overflows from occurring.
The City prohibits the dumping of trash or debris on any public or private property, and also coordinates with Washington
County on their Environmental Services Recycling Program. Both of these efforts help keep trash and debris from
entering the storm sewer system.

CITY OF COTTAGE GROVE - SURFACE WATER MANAGEMENT PLAN
Section 3 — Goals and Policies
3.1 PURPOSE
The primary purpose of the SWMP is to provide guidance on how the City of Cottage Grove intends to manage its
surface water. Over time, significant advancement has been made in our understanding of how natural and man
made systems function in the context of rainfall, infiltration and runoff. New regulations have been created that
reflect increased protection for water bodies and emphasize treatment of stormwater to protect downstream
resources and groundwater.
A number of the City's goals and policies are guided by federal, state, regional and local mandates, while others
arise out of the City's own desire to protect its natural resources in light of its unique character and circumstances.
A number of regulations, strategies and tools have emerged to manage the City's land and water resources
effectively.
Together these regulations, initiatives and programs provide the basis for the strategies and requirements set forth
by the City to guide the protection and management of the water resources within the City. This section of the
SWMP specifically outlines the City's goals and policies related to surface water management. The goals and policies
are consistent with the requirements of Minnesota Rules 8410 and Minnesota Statute 1036.235 (Local Water
Management Plans), and demonstrate a desire, willingness, and commitment by the City to reach and sustain a high
quality of life for its residents.
3.2 CITY OF COTTAGE GROVE
Surface water management is a strong component of the City's overall approach to protecting and preserving the
community's natural resources. The City of Cottage Grove recognizes both the value and impact that surface water
can have on the quality of life in the community. In this plan, the term surface water is used broadly to refer to:
• Wetlands
• Lakes and ponds, either natural or artificial
• The overland runoff resulting from rainfall or snow melt events
• Streams and other natural channels
• The Mississippi River
• Features constructed to temporarily or permanently store runoff such as infiltration areas
Surface water management also includes the infrastructure designed and constructed to convey, control and protect
surface water resources.
The goals and policies form the framework of the stormwater management strategies of the City of Cottage Grove.
A goal is a desired end toward which the City's policies, standards, criteria and rules are directed. A policy is a
governing principle, a means of achieving an established goal. Policies prescribe a general course of conduct that
leads toward goal achievement.
City of Cottage Grove Project No: 48 -05 -214
Surface Water Management Plan 996agim Page 12
Goal k Manage surface and groundwater resources using approaches that meet or exceed regulatory requirements.
Policy 1.1 — The City will meet, or if required, exceed the adopted surface and groundwater protection and
management (including karst- sensitive areas) standards and requirements of the jurisdictional WMO, as well as
those adopted by the Metropolitan Council and the State of Minnesota, including the Total Maximum Daily Load
(TMDL) program and the National Pollutant Discharge Elimination System (NPDES) Phase 2 requirements.
The City will comply with the Lower St. Croix Watershed Management Organization's current Plan (adopted
June, 2005) and with the current rules (adopted February 2008) for those areas of the City within the LSCWMO
jurisdiction. The LSCWMO rules are attached in Appendix F. The City will comply with the South Washington
Watershed District's updated Plan (adopted by the SWWD in November 2007) and the Standards Manual when
it is finalized. As per past discussion and agreement with the SWWD, however, the City will administer the
runoff volume control requirements and wetland impacts in regional stormwater conveyance corridors according
to Policies 6.1 -6.2 and 5.4, respectively, of this Plan.
Policy 1.2 — The City is committed to the goal of nondegradation to area water resources. Upon MPCA approval
of the City's Nondegradation Review, the City will implement the revisions to the City's Storm Water Pollution
Prevention Program (SWPPP) to address nondegradation - as approved.
Policy 1.3 — The City will adhere to the following policies relating to groundwater protection as contained in the
Washington County 2003 -2013 Groundwater Plan:
• Work to coordinate with other local government units for groundwater sensitive areas, wellhead protection
areas, water use contingency and allocation plans and other groundwater issue where the plans may affect
other jurisdictions.
• Adopt a wellhead protection plan; where necessary, create overlay districts and standards and incorporate
into zoning ordinances and other related land use regulations.
• Develop land use regulations to protect groundwater resources based on completed studies and rankings of
groundwater recharge areas.
• Consider requiring a groundwater monitoring plan or groundwater protection plan as part of a permit
application for businesses that store, use, or transport hazardous materials and for properties formerly used
as waste disposal sites or transfer facilities. Where available, use wellhead protection plans to support this
process.
The City will also take into account the recommendations of the completed Phase 1 and 2 efforts of the
Wellhead Protection Plan and the source water assessment completed by the Minnesota Department of Health
in its management of land use activities.
Goal2: Provide adequate flood protection for residents and structures and protect the integrity of conveyance
channels and stormwater detention areas.
Policy 2.1 — Adopt appropriate precipitation events for design of system components.
Storm sewers will be sized /designed using the intensity- duration - frequency curves presented in the MnDOT
Drainage Manual for the 5 -year 24 -hour precipitation event. Lake, natural pond /wetland, and detention pond
high water levels will be based on a 6.3 -inch 24 -hour type II distribution rainfall event.
City of Cottage Grove Project No: 48 -05 -214
Surface Water Management Plan 996agim Page 13
Policy 2.2 — Establish freeboard standards to minimize the potential for flooding of critical structures, such as
buildings.
High water levels shall be established as an area develops or when drainage facilities are constructed for an
area. For stormwater facilities with emergency overflows, the low entry elevation for all new structures must be
a minimum of 3 feet above both the peak surface water elevation for the 100 -year precipitation event and 2
feet above the emergency overflow elevation of any immediately adjacent new stormwater basin. The submitted
grading plan for this basin must identify the direction of overflow and provide adequate flowage easements for
the overflow. For backyard and side -yard conveyance and temporary ponding areas, there must be at least 1
foot between the overland overflow elevation and the low entry of the adjacent structure.
In land- locked areas with no practical emergency overflow, the low entry of new structures shall be a minimum
of 2 feet above the peak water level elevation of back -to -back 100 -year recurrence interval precipitation events,
and at least 5 feet above the peak water surface elevation generated by the critical 100 -year recurrence interval
precipitation event. New land- locked ponds constructed in the jurisdiction of the LSCWMO are subject to the
land locked basin requirements of the LSCWMO, as identified in Section 8.0 of the LSCWMO Rules included in
Appendix F.
Policy 2.3 — Establish peak flow limits to avoid increases in downstream rates caused by development and
protect channel integrity.
At a minimum, peak flow rates after development shall not exceed pre - development peak flow rates for the
critical 1 -year, 2 -year, 10 -year, and 100 -year recurrence interval precipitation events. More restrictive rate
control criteria may be required in order to protect the integrity of downstream conveyance channels. Both the
SWWD and LSCWMO provide guidance as to the acceptable runoff parameters for characterizing an existing
condition, particularly for agricultural runoff. The City adopts the defined parameters of the jurisdictional
Watershed Management Organization (WMO).
Policy 2.4 — Follow watershed authority rules and guidelines in siting detention ponds and other stormwater
management features in karst- sensitive areas.
Guidance from the watershed authorities will be used to determine karst- sensitive areas. Watershed authority
technical guidance and rules as well as the Minnesota Stormwater Manual and guidance from the Minnesota
Department of Health will be followed in determining the suitability of specific sites for certain stormwater
management features and only those features for which the site is suitable will be approved for installation by
the City.
Policy 2.5 — The City will preserve flood storage.
The City shall maintain a policy of "no net loss of storage capacity" in designated stormwater ponding areas.
City of Cottage Grove Project No: 48 -05 -214
Surface Water Management Plan 996agim Page 14
Goal3: Pursue the reduction of Total Phosphorus (TP) and Total Suspended Solids (TSS) loading to water bodies by
compliance, municipal management activities, and public education.
Policy 3.1 — Encourage the incorporation of acceptable Low Impact Development (LID) techniques.
The City recognizes the water quantity and quality benefits provided by incorporating LID techniques into
development within the City. The City is committed to working with developers to incorporate suitable LID
techniques into future development.
Policy 3.2 — Minimum Best Management Practices (BMPs) performance criteria.
The City requires that new development projects include BMPs that at a minimum achieve post - development
reductions in TP and TSS by 50% and 80 %, respectively.
Policy 3.3 — Comply with the NPDES Phase II program administered by the Minnesota Pollution Control Agency
(MPCA).
This program is focused on regulating stormwater runoff. The City of Cottage Grove will comply with this
program by developing and submitting appropriate documentation as required by the program and performing
related tasks as appropriate.
Policy 3.4 — Promote compliance with zero - phosphorus content fertilizer legislation.
Effective January 1, 2004, Minnesota state law bans application of fertilizer containing phosphate to lawns with
some exceptions, such as, where a recent soil test has shown the lawn soil is deficient in phosphorus. State law
also requires clean -up of any fertilizer spread or spilled on paved surfaces. The City will promote awareness of
this law in public education efforts.
Policy 3.5 — Reduce the use of sand in street de -icing procedures.
The City strives to tailor applications of sand for ice control in a way which balances public safety with
environmental quality. The City recognizes that excessive application of sand on impervious surfaces results in
significant sedimentation of downstream ponds and basins.
Policy 3.6 — Street sweeping to protect water quality will, at a minimum, be carried out in the spring and fall.
The City undertakes two seasonal street sweeping efforts. Streets are swept once in the spring as soon as
practical. Streets are swept once in the autumn, generally after most leaves have fallen and targeting mature
tree areas. Sweeping operations are conducted as necessary throughout the year.
The City intends to keep informed of street sweeping technologies and evaluate replacing obsolete equipment
with more efficient updated equipment, subject to available funding and according to capital improvement
priorities.
City of Cottage Grove Project No: 48 -05 -214
Surface Water Management Plan 996agim Page 15
Policy 3.7 — Implement a storm system maintenance program based on objective standards.
The City will continue to be actively engaged in stormwater inspection, operation and maintenance, and repair
of the stormwater system on a day -to -day basis. The City will follow a formal inspection, cleaning, and repair
schedule. As required under the City's NPDES Municipal Separate Storm Sewer System (MS4) permit, at least
20% of the system will be inspected annually. Frequency of maintenance is event -based and driven by
experience and inspection results.
Policy 3.8 — Dumping of wastes into the storm drainage system is illegal.
The City prohibits, through ordinance, the discharge of foreign material into the stormwater system, including
refuse, yard wastes, sewage, industrial waste or other substances. Examples of other substances include
materials such as oil, gasoline, antifreeze, paint, solvent, herbicides /pesticides, pet waste and other ecological
harmful chemicals.
Policy 3.9 — The City will have spill response capability.
The City has access to spill clean -up kits in selected locations. The City will review its current program for spill
response capability within one year of the date of adoption of this plan by the City Council, and if warranted,
develop improvements in its spill response capability. Karst - sensitive areas as identified by the Minnesota
Department of Health and the appropriate watershed management organization will have spill response plans.
Policy 3.10 — Carry out public education.
The City will actively implement an ongoing public education program. The program is directed primarily at City
residents. Its objectives are to reduce phosphorus and sediment loadings to water bodies. Newsletter mailings
and brochures are primary vehicles for the program. The City also seeks out educational institutions within its
community to implement programs and /or activities. The City is participating in the Washington County shared
water resources educator program.
Goal 4. Classify and effectively manage water bodies in the community to achieve watershed management
organization, state, and federal regulatory agency standards.
Policy 4.1 — The City adopts the classification and water quality protection standards for significant water bodies
within the City of Cottage Grove as specified in each of the current watershed management organization plans.
The classification and standards of the South Washington Watershed District Plan, adopted in November 2007,
will be applied to Gables Lake, Ravine Lake and the Mississippi River and the classification and standards of the
Lower St. Croix Watershed Plan, adopted in June 2005, will be applied to O'Conners Creek.
Policy 4.2 — Develop guidelines for managing ponds with no developed public access.
The City will implement adequate maintenance for all ponds that are part of the City's stormwater management
system to minimize as much as reasonably possible blockages of inlets to- and outlets from- ponds, to maintain
the original flood storage capacity, and to insure that each pond functions adequately as part of the City's flood
management system.
City of Cottage Grove Project No: 48 -05 -214
Surface Water Management Plan 996agim Page 16
Water quality or habitat improvement efforts for ponds without a developed public access must be balanced
against overall public benefits. Property owners abutting a pond may desire that pond to provide or improve
functions beyond what the City intends through this plan, such as improvement of aesthetics. In such cases, the
City will work with affected residents in an advisory capacity to improve the pond environment. Where a city-
wide benefit and city -wide knowledge can be gained, however, the City may elect to either assist with or
implement itself, management measures on a specific pond.
Policy 4.3 — The City requires adequate pretreatment of stormwater runoff from development and
redevelopment activities prior to discharge into all waterbodies.
Goal 5. Classify and manage wetlands in the community.
Policy 5.1 — The City will assess the function and value of wetlands.
Approximately 2/3 of the wetlands within the City were assessed as part of an effort by the South Washington
Watershed District in 1998. The inventory data associated with that assessment will be used by the City to guide
management of those wetlands. The City shall establish a schedule for completing a function and value
assessment for the remaining wetland complexes in the City (approximately 40, located in the eastern third of
the City). That schedule will be phased so that the assessments are completed before subdivision of the affected
areas occurs.
Policy 5.2 — The City will develop and apply wetland buffer standards.
Wetland buffer zones are required on all public and private property which abuts water body. The City will adopt
the applicable wetland buffer standards of the jurisdictional WMO, or where no standards exist, will establish
minimum buffer widths and types based on wetland size, function, and value (see Chapter 4). The buffer
standards will be applied to wetlands within parcels that are the subject of new development activity that must
be approved by the City, or in accordance with the rules of the jurisdictional WMO.
Policy 5.3 — The City will administer the overall wetland protection and preservation programs.
The City will act as the Local Government Unit (LGU) for administration of the Wetland Conservation Act (WCA)
of 1991 and all subsequent amendments in all portions of the City. This will include the application of officially
adopted wetland protection standards promulgated through the WCA, NPDES MS4 permit, and the watershed
management organizations covering the City as they relate to:
• wetland impact sequencing
• pre- treatment of stormwater prior to discharge to wetlands
• wetland replacement
The City will uphold the objective of no net loss in wetland functions and values within the City and comply with
the most current WCA regulations for mitigation and acreage requirements for any filling, draining, or
excavation of a wetland.
City of Cottage Grove Project No: 48 -05 -214
Surface Water Management Plan 996agim Page 17
Policy 5.4 — Where it is infeasible to meet watershed authority standards for wetland protection within the
regional stormwater conveyance corridors identified on Map 3 in Appendix A and also discussed in Section 4.3,
the City will work with the appropriate watershed authority to allow the corridor to serve a regional stormwater
conveyance function.
The regional stormwater conveyance corridors identified on Map 3 in Appendix A of this plan are essential
components of the natural and man -made stormwater conveyance system that carries runoff from the
communities of Lake Elmo, Woodbury, and Cottage Grove to the Mississippi River. In addition, these
conveyance routes have been identified as regionally important stormwater management features in past City
and SWWD plans. The corridors are particularly important for conveyance of flood flows that could otherwise
cause significant property damage. The City will work with the SWWD to manage wetland impacts and still
allow use of the regional conveyance corridor.
Goats.. Regulate new development and redevelopment activities.
Policy 6.1 — The City will comply with watershed authority and NPDES Construction Permit standards for
management of stormwater runoff for all development activity disturbing 1 acre or more of land or according to
the rules /regulations of the appropriate watershed authority within which the project is located, which ever is
more restrictive. For projects within the jurisdiction of the LSCWMO, specific thresholds that trigger LSCWMO
rules are included in Section 1.2 of the LSCWMO rules.
For areas of the City within the Lower St. Croix Watershed Management Organization (LSCWMO), the City will
comply with LSCWMO standards for runoff volume reduction and stormwater treatment as presented in their
Rules and Regulations adopted February 13, 2008 and effective June 1, 2008. For areas of the City within the
South Washington Watershed District (SWWD), the City will comply with runoff volume reduction and
stormwater treatment as presented in SWWD Plan adopted November 2007, except that in place of the variable
area - specific volume control requirements, the City shall apply a uniform volume control requirement equal to
infiltrating 1 " of runoff from new impervious areas of a development. Where meeting the standards referred to
above is not adequate to meet the nondegradation requirements of the City's MS4 permit, the City will require
additional controls in order to meet those MS4 permit requirements.
For re- development projects, the volume control standard will apply to new impervious area, which is the
difference between the total impervious area of the site before the re- development activity and total impervious
area for the post -re- development condition.
Where regional facilities are used to manage stormwater from development activity, the regional facilities will be
constructed and operational prior to development.
Policy 6.2 — Where infiltration to fully meet the volume control measure is not desirable or is impossible, an
Alternative Sequencing procedure will be applied to achieve compliance.
Based on guidance from the watershed authorities, the MN Department of Health, and the State of Minnesota
Stormwater Manual, the City will not allow infiltration practices:
• For runoff from fueling and vehicle maintenance facilities
• Within HSG D type soils
City of Cottage Grove Project No: 48 -05 -214
Surface Water Management Plan 996agim Page 18
• Within 100 feet of a private well, within the emergency response zone for a wellhead protection area
• Within 50 feet of a septic tank of drain field
• On areas with less than 3 feet of vertical separation from the bottom of the infiltration system to the
elevation of the seasonal high groundwater elevation or top of non -karst bedrock
• Within 300 feet of an identified sinkhole or other karst feature
At the discretion of the City Engineer, infiltration practices may not be allowed:
• Within a vulnerable (very high, high, or moderate vulnerability) Drinking Water Supply Area
For runoff from a Potential Stormwater Hotspot (PSH) as defined in the State of Minnesota Stormwater
Manual (2005)
• In a known or suspected karst- sensitive area
For areas within the jurisdiction of the Lower St. Croix Watershed Management Organization, the Alternative
Compliance Sequencing procedure outlined in the LSCWMO rules adopted in February 2008 will be followed.
For areas outside of the LSCWMO, the following Alternative Compliance Sequencing will be followed:
• The applicant will provide documentation for why infiltration is not feasible or allowable
The applicant will reduce impervious surface associated with the proposed action to the maximum extent
practical
The applicant will use to the maximum extent practical filtration and biofiltration practices, using an
underdrain and an impermeable liner, that are sized to meet the volume control requirement for the site.
The MN Stormwater Manual will be used as the definitive guide in designing and installing the
filtration /biofiltration feature. If the applicant can show that the full volume of runoff for the appropriate
volume control standard is filtered, the volume control requirement will be deemed to have been met. Other
alternative BMPs will also be considered by the City if the applicant can demonstrate equivalency with the
City's requirement.
If the applicant has followed the Alternative Sequencing procedure above and the full runoff volume control
standard is still not met, the applicant will pay a cash dedication as a last resort. The procedure for calculating
the appropriate cash dedication amount is presented in Section 5.4 of this Plan and the revenue from cash
dedications will be ear - marked exclusively for water quality or runoff volume reduction improvements in the City.
Policy 6.3 — Pursue infiltration of stormwater runoff as appropriate primarily for water quality protection, stream
baseflow preservation, and channel protection.
Infiltration of stormwater should be applied as a technique to limit peak flows and runoff volumes for
precipitation events greater than a 1 -year event (2.4 inches of rainfall in 24 hours) only when reviewed and
approved by the City Engineer. Even when approved, outlets /emergency overflows need to be provided for the
infiltration areas to assure that freeboard requirements in Policy 2.2 are met for adjacent low structures
Policy 6.4 — Soil decompaction
The City encourages the practice of re- establishing the native infiltrative capacity of soils upon completion of
mass grading activities. During the development review process, the City will recommend that soil
City of Cottage Grove Project No: 48 -05 -214
Surface Water Management Plan 996agim Page 19
decompaction, by means of deep ripping to a depth of at least 18 inches, be incorporated into site restoration
activities. The volume control benefit provided by the deep ripping activity can be applied toward the City's
volume control requirement, per the methodology outlined in the SWWD Standards Manual.
Policy 6.5 — Detention basin design standards.
When new ponds are constructed for stormwater management purposes, they will be constructed to meet the
City's standards for detention basin design (see Section 6.1.4), as well as those of the jurisdictional WMO. The
sizing of the wet volume of the pond can be adjusted to account for runoff volume reduction features in the
pond's watershed.
Policy 6.6 — Development pays for itself.
Storm drainage system financing shall be by trunk area assessments against benefiting properties and storm
sewer facilities. All new developments shall be required to pay the prorated cost to dedicate land and construct
a stormwater treatment facility meeting City requirements.
Policy 6.7 — Additional treatment can be required to protect downstream priority water bodies and /or meet
jurisdictional WMO requirements.
The City may require, as a condition of approval to develop vacant land or redevelop existing sites, the
construction by the developer of additional treatment features (to include ponds) or installation of appropriate
best management practices over and above that required under Policy 6.1 -6.2. This may be required even when
existing improvements or ponds already are in place. The City can require these practices when it is necessary to
protect the water quality of downstream priority water bodies. The City shall apply these requirements if
necessary in order to meet the phosphorus load targets for Gables Lake, Ravine Park Lake and the Mississippi
River as outlined in the South Washington Watershed District Plan (2007) and for O'Conner's Creek and Lake as
outlined in the Lower St. Croix Watershed management organization Plan (2005).
Policy 6.8 — Control erosion at construction sites.
The City requires that applications for new or redevelopment activity include in their applications for City review,
a SWPPP as required under the NPDES construction permit in effect at the time of review. Construction sites will
be inspected to ensure compliance with the existing erosion and sediment control ordinance, jurisdictional WMO
requirements, and with the construction site permit under NPDES Phase II rules administered by the MPCA.
Inspections are performed weekly during the construction period. A plan review process and a financial security
instrument are the primary instruments used to establish a basis for compliance.
Erosion and sediment control best management practices as outlined in "Protecting Water Quality in Urban
Areas — Best Management Practices for Minnesota" by the MPCA (2000) will be required and must be shown
on required submittals to the City for approval. Any street sweeping conducted by the City to remove erosional
debris from streets will be charged to the owner of the property.
