Re: Receive Information: BWSR Clean Water Fund Grant Submittals
Background /Discussion
The Clean Water Fund was established to implement part of Article XI, Section 15, of the
Minnesota Constitution, with the purpose of protection, enhancing, and restoring water quality
in lakes, rivers, and streams in addition to protecting groundwater and drinking water sources
from degradation. The primary purpose of activities funded with grants associated with the
Clean Water Fund is the control or prevention of chemical or nutrient runoff, soil erosion,
sedimentation, runoff volume or materials that affect human or aquatic system health. Eligible
projects can consist of structural practices, technical assistance or non - structural measures
and best management practices. Local units of government are eligible to receive grant funds
if they are working under an approved watershed management plan. An eligible activity must
comply with the following three requirements: 1) all structural practices must be designed and
maintained for a minimum effective life of ten years, 2) operation and maintenance for the life
of the practice is included with the design standards, 3) an inspection schedule and procedure
shall be included as a component of maintaining the effectiveness of the practice.
The South Washington Watershed District (SWWD) submitted three projects to BWSR for the
FY 2010 Clean Water Grant Fund on behalf of the City, because cities were not eligible to
submit based on the classification of projects, but watershed districts were eligible.
Project #1: C -P6 located south of Pine Tree Valley Park in the valley between Irvin Avenue
and Irish Avenue. The total project cost is $423,800 (Grant request of $339,040 with a match
of $84,760)
The proposed project includes the excavation and construction of 3 water quality cells at all
three of the discharges into Pond C -P6 and an infiltration Swale running the length of the
ravine. The first cell at the far north end of the existing Pond C -P6 will be sized to
accommodate a roughly 200 acre watershed. The cell will be designed to dissipate the energy
of discharge from the 48 -inch inlet currently causing erosion and a skimmer outlet will be
provided.
Discharge from the northern pond will begin a meandering infiltration Swale, through the
bottom of the existing ravine. The Swale will include grade control structures to slow flow
velocities and promote infiltration. The Swale will be planted with native vegetation, including
shrubs, to protect the channel from erosion.
A second wet pond cell will be sized to accommodate a roughly 3 acre watershed. The
proposed feature acts as a pre- treatment sediment trap, prior to overflowing into the adjacent
infiltration swale. The final cell is proposed at the downstream end of an approximately 80
acre watershed. Due to the steep slopes in this area, the size of this feature is limited. The
proposed feature will include a skimmer outlet.
Project #2: ED -P5 located in the open ravine space south of Kingston Park and north of 80
Street with a total project cost of $800,000 (Grant request of $640,000 with a match of
$160,000)
The proposed ED -P5 Pond Improvements Project includes the excavation of two water quality
features within the vicinity of the existing ED -P5. These two features will intercept certain inlets
into pond ED -P5 for treatment prior to discharging back into ED -P5.
The north feature will include a two -cell design providing water quality treatment for a 90 acre
drainage area. The first cell will be a wet pond providing pre- treatment for storm water runoff
discharging into the second cell, an infiltration basin. The wet pond will have an approximate
surface area of 0.8 acres and a wet volume of approximately 3.3 acre -feet. The infiltration
basin will have an approximate surface area of 0.5 acres. Sized to infiltrate 1 -inch of runoff
from the existing impervious area (approximately 15.9 acres) draining to the pond, the
infiltration basin will have a volume of approximately 1.3 acre feet and assuming a reasonable
existing infiltration rate (based on HSG B soils) the basin will drain down in less than 48 hours.
The infiltration basin will be restored with native vegetation to provide a deep root structure to
maximize infiltration rates. This native vegetation will have the ability to withstand prolonged
inundation times. A skimmer structure will also be provided.
Project #3: SPP -A10 located at Wheels of Travel with a total project cost of $807,200 (Grant
request of $645,760 with a match of $161,440)
Drainage from the northerly agricultural areas drains south via a ravine, crossing under 70th
Street, into drainage area SPP -A10. Flows then drain overland via a ravine across the Wheels
of Travel Incorporated property (PID 07- 027 -21 -22 -0001) prior to discharging to the TH 61
Right -Of -Way (ROW).
This project proposes to purchase the Wheels of Travel Incorporated property, remove the
existing buildings, and excavate a regional storm water pond on site. The proposed design will
divert the low flows from the existing ravine into a two cell pond to provide water quality
treatment. The first cell of the proposed two cell pond will be a wet pond having an
approximate surface area of 0.4 acres and a wet volume of approximately 1.5 acre -feet. This
cell will provide pre- treatment for storm water runoff prior to discharging into the second cell,
an infiltration basin that will be sized to maximize surface area within the parcel. Both cells will
be constructed following guidance provided in the MN Stormwater Manual. Excessive flows
will bypass the pond and continue toward the TH 61 ROW.
This project is a collaborative effort between the City of Cottage Grove and the South
Washington Watershed District (SWWD). Water quality pond improvements in the vicinity of
SPP -A10 are specifically identified as a future implementation item in Cottage Grove's
2
approved Local Surface Water Management Plan. Further, this project will adress inter -
community flow issues between Cottage Grove and St. Paul Park as identified in SWWD's
watershed management plan and bring the watershed into compliance with SWWD's total
phosphorus loading standard of 0.22 Ibs /acre /year that is applicable to all watersheds' tributary
to the Mississippi River.
FY 2010 Clean Water Fund
Water Quality Comprehensive Project Narrative
The entire narrative portion of the application should be no more than 3
pages in length and should include the following topics as section
headings
Title: (10 words or less):
C -P6 Pond Improvments
Project Abstract (30 words or less):
The proposed project will provide protection of wetlands and the Mississippi
River by improving an existing stormwater basin to increase infiltration and
reduce stormwater runoff and associated nutrients and sediment.
Overall Project Narrative (500 words or less): This section of the narrative
should describe the level of project partners' coordination, cooperation
and community support for the project, projects that have proven to be
successful in similar circumstances or prior successful projects and the
level of project partners' project management expertise and experience and
any habitat benefits that may result from this project.
Pond C -P6 is located in the north central part of Cottage Grove and currently
provides stormwater rate control for a 285 acre watershed consisting primarily of
residential land uses. The existing pond C -P6 reduces discharge rates to
downstream basins, but does not provide water quality treatment. The existing
basin is within a ravine, surrounded on three sides by steep slopes, with an
earthen embankment at the downstream end forming the ponding area. Pond C-
P6 discharges via storm sewer to the south through a series of City ponds and
DNR Public Waters wetlands, eventually reaching the Mississippi River.
The proposed project includes the excavation and construction of 3 water quality
cells at all three of the discharges into Pond C -P6 and an infiltration Swale
running the length of the ravine. The first cell at the far north end of the existing
Pond C -P6 will be sized to accommodate a roughly 200 acre watershed. The
cell will be designed to dissipate the energy of discharge from the 48 -inch inlet
currently causing erosion and a skimmer outlet will be provided.
Discharge from the northern pond will begin a meandering infiltration Swale,
through the bottom of the existing ravine. The Swale will include grade control
structures to slow flow velocities and promote infiltration. The Swale will be
planted with native vegetation, including shrubs, to protect the channel from
erosion.
Form FY10 -1: Project Narrative
A second wet pond cell will be sized to accommodate a roughly 3 acre
watershed. The proposed feature acts as a pre- treatment sediment trap, prior to
overflowing into the adjacent infiltration Swale. The final cell is proposed at the
downstream end of an approximately 80 acre watershed. Due to the steep
slopes in this area, the size of this feature is limited. The proposed feature will
include a skimmer outlet.
The City of Cottage Grove and the South Washington Watershed District
(SWWD) are committed to this project. Proposed improvements are specifically
identified in Cottage Grove's approved Local Surface Water Management Plan.
Further, SWWD's Watershed Management Plan sets of a goal of maintaining, or
where practical improving, the water quality of wetlands and water bodies within
the District. The proposed improvements will help SWWD reach its goal.
Cottage Grove and SWWD have a long history of working together to manage
Water resources in the District. Recently, the City and District partnered to
complete the ED -P6 water quality improvements project that corrected an
ongoing erosion issue, removed deposited material from a downstream wetland,
and excavated a pretreatment cell upstream of this existing wetland. The
construction costs for this project were paid for by the South Washington
Watershed District, with the City performing the engineering and administration
for the project. A similar arangement will be used for this proposed project
utilizing CWF grant funding.
Cottage Grove has years of project management experience on projects
involving water resource management. In addition to the ED -P6 project, the City
has successfully completed a $1.4 million pond improvement/expansion project
in Hamlet Park.
Explain how this project will mitigate or prevent current or future water
quality impairments.
The City's existing PonclNET model was used to generate pollutant load
reduction estimates associated with the proposed water quality features. The
PondNET model was originally developed for the City's Nondegradation Review
and includes a high level of detail regarding the land use inputs and individually
models water quality treatment features. Once the project moves forward,
additional hydraulic and water quality modeling will be necessary to design the
dimensions of the ponds and infiltration swale and better estimate pollutant load
reductions of the improvements. The current model shows annual reductions of
15 acre -ft (10 %) of runoff, 76 Ibs (43 %) of total phosphorus, and 40,695 Ibs
(67 %) of total suspended solids. Water quality improvements as a result of this
project will help prevent degradation of downgradient wetlands and further
impairment of the Mississippi River.

Form FY10 -1: Project Narrative 2
The South Washington Watershed District is generally characterized by soils with
high infiltration capacity. Thus, BMPs that increase contact time between
stormwater runoff and the land are typically highly effective. The existing basin
provides stormwater runoff rate control for a 285 acre watershed. The proposed
improvements will provide stormwater runoff volume control, increased
infiltration, and water quality treatment. Ultimately, by increasing contact time to
keep water on the land, the proposed improvements will result in an annual
reduction of 15 acre -ft of stormwater runoff mostly due to increased infiltration.
Identify long -term inspections and maintenance needs of the project
and how these activities will be accomplished.
Inspection and maintenance of the C -P6 Pond improvements is the responsibility
of Cottage Grove, being part of the City's overall storm water system
maintenance program. This maintenance program is identified in the City's Storm
Water Pollution Prevention Plan (SWPPP), which is part of Cottage Grove's
Municipal Separate Storm Sewer System (MS4) permit responsibility. The City
funds this program through their Storm Water Utility. Regular pond inspection
and maintenance occurs a minimum of once every 5- years, or more frequently as
needed.
Describe the coordination of this project with local groundwater plans.
The project area is located within a drinking water supply management area
(DWSMA) identified in the City of Cottage Grove Wellhead Protection Plan (WPP),
Part 2 (2006). Infiltration improvements completed as part of this project will be
designed in accordance with guidance provided in the WPP and the 2003
Washington County Groundwater Plan.
Please indicate any permits this project will require. Identify the current
stage of the permitting process.
This project will be carried out under the NPDES general construction permit and
will require SWWD review. City of Cottage Grove staff will be responsible for all
necessary permit and review processes. Permitting and review processes will be
initiated when funding is secured.

Water Quality Comprehensive Project Narrative
The entire narrative portion of the application should be no more than 3
pages in length and should include the following topics as section
headings
Title: (10 words or less):
ED -P5 Pond Improvements
Project Abstract (30 words or less):
The proposed project will provide protection of wetlands and the Mississippi
River by improving an existing dry stormwater basin to increase infiltration,
reducing stormwater runoff and associated nutrients and sediment.
Overall Project Narrative (500 words or less): This section of the narrative
should describe the level of project partners' coordination, cooperation
and community support for the project, projects that have proven to be
successful in similar circumstances or prior successful projects and the
level of project partners' project management expertise and experience and
any habitat benefits that may result from this project.
The existing pond ED -P5 provides stormwater rate control for a 540 acre
tributary area, which includes a mixture of land uses including single family
residential, school property, and City park. Currently pond ED -P5 provides
essentially no storm water quality treatment for the tributary area.
The proposed ED -P5 Pond Improvements Project includes the excavation of two
water quality features within the vicinity of the existing ED -P5. These two
features will intercept certain inlets into pond ED -P5 for treatment prior to
discharging back into ED -P5.
The north feature will include a two -cell design providing water quality treatment
for a 90 acre drainage area. The first cell will be a wet pond providing pre-
treatment for storm water runoff discharging into the second cell, an infiltration

FY 2010 Clean Water Fund
Water Quality Comprehensive Project Narrative
The entire narrative portion of the application should be no more than 3
pages in length and should include the following topics as section
headings
Title: (10 words or less):
SPP -A 10 Pond Improvements
Project Abstract (30 words or less):
The proposed project will address inter - community flow issues identified in
SWWD's watershed management plan and protect the Mississippi River from
excess nutrient loading.
Overall Project Narrative (500 words or less): This section of the narrative
should describe the level of project partners' coordination, cooperation
and community support for the project, projects that have proven to be
successful in similar circumstances or prior successful projects and the
level of project partners' project management expertise and experience and
any habitat benefits that may result from this project.
Drainage area SPP -A10 is located along the border of Cottage Grove and St.
Paul Park, in the vicinity of 70th Street and Trunk Highway 61 (TH 61).
Approximately 125 acres drain south through SPP -A10 and under TH 61 via a
number of culverts. Flows then travel into St. Paul Park and ultimately the
Mississippi River. Land cover tributary to SPP -A10 includes a mix of primarily
rural residential and agricultural land. Future development in this area will
transition the agricultural land uses to low density residential.
Drainage from the northerly agricultural areas drains south via a ravine, crossing
under 70th Street, into drainage area SPP -A10. Flows then drain overland via a
ravine across the Wheels of Travel Incorporated property (PID 07- 027- 21 -22-
0001) prior to discharging to the TH 61 Right -Of -Way (ROW).
This project proposes to purchase the Wheels of Travel Incorporated property,
remove the existing buildings, and excavate a regional storm water pond on site.
The proposed design will divert the low flows from the existing ravine into a two
cell pond to provide water quality treatment. The first cell of the proposed two
cell pond will be a wet pond having an approximate surface area of 0.4 acres and
a wet volume of approximately 1.5 acre -feet. This cell will provide pre- treatment
for storm water runoff prior to discharging into the second cell, an infiltration
basin that will be sized to maximize surface area within the parcel. Both cells will
Form FY10 -1: Project Narrative
be constructed following guidance provided in the MN Stormwater Manual.
Excessive flows will bypass the pond and continue toward the TH 61 ROW.
This project is a collaborative effort between the City of Cottage Grove and the
South Washington Watershed District (SWWD). Water quality pond
improvements in the vicinity of SPP -A10 are specifically identified as a future
implementation item in Cottage Grove's approved Local Surface Water
Management Plan. Further, this project will adress inter - community flow issues
between Cottage Grove and St. Paul Park as identified in SWWD's watershed
management plan and bring the watershed into compliance with SWWD's total
phosphorus loading standard of 0.22 Ibs /acre /year that is applicable to all
watersheds tributary to the Mississippi River.
Cottage Grove and SWWD have a long history of working together to manage
Water resources in the District. Most recently, the City and District partnered to
complete the ED -P6 water quality improvements project in the summer of 2009
that corrected an ongoing erosion issue, removed deposited material from a
downstream wetland, and excavated a pretreatment cell upstream of the existing
wetland. The construction costs for the project were paid for by the South
Washington Watershed District, with the City performing the engineering and
administration for the project. A similar arangement will be used for this
proposed project utilizing CWF grant funding.
Cottage Grove has years of project management experience and expertise on
water resource management projects. In addition to the ED -P6 project, the City
has successfully completed a $1.4 million pond improvement/expansion project
in Hamlet Park.
Explain how this project will mitigate or prevent current or future water
quality impairments.
The City of Cottage Grove's existing PondNET model was used to estimate
pollutant load reductions associated with the proposed project. The PoncINET
model was originally developed for the City's Nondegradation Review and
includes a high level of detail regarding the land use inputs and individually
models water quality treatment features. The results of the PoncINET model are
presented in the following table. The model shows annual reductions of 14 acre -
ft (32 %) of stormwater runoff, 25 Ibs (51%) of total phosphorus, and 12,839 Ibs
(58 %) of total suspended solids. Water quality improvements as a result of this
project will help mitigate excessive nutrient loading to the Mississippi River.
How will this project address the hydrologic function of the immediate
affected watershed and keep water on the land?
The South Washington Watershed District is generally characterized by soils with
high infiltration capacity. Thus, BMPs that increase contact time between
stormwater runoff and the land are typically highly effective. The proposed
improvements will provide stormwater runoff rate and volume control, increased
Form FY10 -1: Project Narrative
infiltration, and water quality treatment. Ultimately, by increasing contact time to
keep water on the land, the proposed improvements will result in an annual
reduction of 14 acre -ft of stormwater runoff mostly due to increased infiltration.
Identify long -term inspections and maintenance needs of the project
and how these activities will be accomplished.
Inspection and maintenance of the SPP -A10 Pond improvements is the
responsibility of Cottage Grove, being part of the City's overall storm water
system maintenance program. This maintenance program is identified in the
City's Storm Water Pollution Prevention Plan (SWPPP), which is part of Cottage
Grove's Municipal Separate Storm Sewer System (MS4) permit responsibility.
The City funds this program through their Storm Water Utility. Regular pond
inspection and maintenance occurs a minimum of once every 5- years, or more
frequently as needed.
Describe the coordination of this project with local groundwater plans.
The project area is located outside of municipal wellhead protection areas. The
South Washington Watershed District watershed management plan identifies area
soils as having high to very high infiltration potential and area groundwater as
having moderate -high to high sensitivity to pollution. By utilizing a two -cell design
that incorporates pre- treatment prior to infiltration, this project takes appropriate
steps to limit the risk of groundwater contamination.
Please indicate any permits this project will require. Identify the current
stage of the permitting process.
This project will be carried out under the NPDES general construction permit and
will require SWWD review. City of Cottage Grove staff will be responsible for all
necessary permit and review processes. Permitting and review processes will be
initiated when funding is secured.
Form FY10 -1: Project Narrative
