The purpose of this program is to engage community groups for the installation of community accessible rain gardens and other water quality best management practices in Ramsey County. The goal is to install 6-12 storm water best management projects that will help protect and improve water quality of surrounding lakes. The installed practices will reduce an estimated 10 acre-feet of storm water runoff, 9 pounds of phosphorous, and 3 tons of sediment annually. Significant measurable outputs, with development of long-term partnerships, are primary objectives for this program.
Ramsey County SWCD is applying to continue the implementation of its popular and successful well sealing cost-share program to help protect the groundwater, especially in highly vulnerable drinking water supply management areas, by permanently and professionally sealing between 115 and 140 abandoned wells in the county.
At 410 acres, Lake Owasso is the largest lake in the Grass Lake Water Management Organization (GLWMO) and one of the most pristine. Maintaining the lakes water quality is a priority for the GLWMO. A long urbanized area along Aladdin Street in Roseville currently lacks stormwater features to remove pollutants and reduce water volume. The rainwater from this area drains directly to a wetland which is hydrologically connected to Lake Owasso. Adjacent to the residential area is a 0.5 acre parking lot which drains into a ditch which eventually enters the same wetland.
A direct appropriation of $400,000 in FY 2010 for the Anoka Conservation District (ACD) is for the metropolitan landscape restoration program for water quality and improvement projects in the seven-county metro area (the law also provides $600,000 for this purpose in FY2011).

The Rice Creek Watershed District (RCWD) is proposing to improve the water quality of stormwater runoff to Bald Eagle Lake through installation of a new wet pond and iron-enhanced sand filter (IESF) on Ramsey County Ditch #11. In partnership with White Bear Township, this project will remove approximately 43 pounds of phosphorus from runoff annually and builds upon the extensive work undertaken by the RCWD to improve water quality in Bald Eagle Lake.
Ramsey-Washington Metro Watershed District (RWMWD) will improve water quality in Casey Lake and ultimately Kohlman Lake through the installation of approximately 25 rain gardens on priority properties identified as part of the Casey Lake Urban Stormwater Retrofit Assessment completed by Ramsey Conservation District (RCD) in 2011.
Lambert Creek discharges into Vadnais Lake, the final impoundment reservoir containing the potable water supply for the city of St. Paul and eight nearby suburbs. Monitoring data indicates high nutrient levels and the creek is listed by the State as having high bacterial levels. In-stream work along Lambert Creek has been maximized with restoration improvements achieving nutrient load reduction. The next step to further improve water quality is to concentrate on restoration efforts on a subwatershed level.
The Ramsey-Washington Metro Watershed District (District) has determined that large impervious sites (like churches, commercial sites, and schools) are more economical for stormwater management retrofit projects than distributed small projects along roadways. The District began assessing church sites for retrofit opportunities in 2013 and will continue this effort in 2014. Church congregations have been receptive to partnering with the watershed district.
Lambert Creek is wholly within the Vadnais Lake Area Water Management Area. Vadnais Lake is the drinking water reservoir for the City of St. Paul and surrounding communities. Lambert Creek has elevated bacteria and nutrient levels and water quality in Vadnais Lake will not improve unless there is a reduction in the phosphorus loading from Lambert Creek.
The Ramsey-Washington Metro Watershed District (RWMWD) is responsible for the protection and restoration of the water quality of 20 lakes and 5 creeks within its boundary. Permit and voluntary cost share programs serve to slowly redevelop the watershed to the benefit of these water bodies. However, additional projects are needed- not only to implement green infrastructure in areas that need extra restoration and protection, but also to foster new relationships between citizens and the RWMWD to rally together in a common goal to the benefit of their water resources.
The Fairview Avenue storm sewer system is under capacity and stormwater runoff reaches the pipe faster than the pipes can convey the water downstream. This causes the system to surcharge, causing arterial street flooding, local street flooding, inundation of open spaces, as well as private property damage. This storm sewer system is directly connected to several significant regional water bodies.
From 2011 to 2013, the full reconstruction of University Avenue in Saint Paul for the Central Corridor Light Rail Transit (CCLRT) presents a unique opportunity to improve the quality of stormwater runoff from the Corridor that will not be seen again. Assistance from the Clean Water funds will augment large investments being made by Capitol Region Watershed District, Saint Paul, Ramsey County, and Metropolitan Council implementing highly visible, green infrastructure practices in this transportation corridor to achieve significant stormwater volume reduction and water quality improvements.
Past and current monitoring data has shown Ramsey County's Lambert Creek has high levels of total phosphorus (TP), anywhere from 0.14 mg/L to 0.30 mg/L, which is above the proposed State standard of 0.10 mg/L for streams in the Central Region.
Lambert Creek is wholly within the Vadnais Lake Area Water Management Organization (VLAWMO) and is located in northeastern Ramsey County. Lambert Creek is surrounded by mainly residential land use and flows through three communities before discharging into East Vadnais Lake, which is the final impoundment reservoir containing the water supply that the Saint Paul Regional Water Services (SPRWS) treats and then distributes to thirteen municipalities including the city of St. Paul.
Capitol Region Watershed District and the City of Lauderdale seek to improve water quality and flood control functions of Seminary Pond in Lauderdale. The project partners propose improvements to the pond including: 1) expansion of the pond?s storage area and 2) construction of an iron-enhanced sand filter. These improvements were identified as being the most cost-effective and will remove an estimated additional 2 tons of sediment and 9 pounds of phosphorus annually.
The Rice Creek Watershed District is proposing to improve water quality and habitat in Locke Lake and Lower Rice Creek by stabilizing stream banks and bluffs on Lower Rice Creek, reducing in-stream erosion and sediment delivery to Locke Lake, and improving in-stream habitat complexity for fish and invertebrates. Eleven bank stabilization practices would be installed over a continuous 5,400-foot reach in Lower Rice Creek. The anticipated outcome of this project is the prevention of 2,874 tons per year of sediment, which is 58% of the sediment reduction goals for Lower Rice Creek.
The Kohlman Lake TMDL calls for the reduction of nutrients from watershed and in-lake loading. A major source of phosphorus loading is from the impervious areas in the District (roads, interstates, roofs, and parking lots). In the analysis of the Kohlman Lake watershed, one major land use feature stands out - Maplewood Mall. The District identified that retrofitting the Mall parking areas to infiltrate at least one inch of runoff would result in a large reduction in phosphorus to Kohlman Creek and the lake.

Within this area, one major land use feature stands out - Maplewood Mall. Retrofitting the Mall parking areas to infiltrate at least one inch of stormwater runoff will result in a large reduction in phosphorus to Kohlman Creek and the lake.
Through a long standing partnership, this project will continue to implement a process formalized with a 2010 Clean Water Fund Grant to conduct stormwater sub-watershed assessments. The goal of the sub-watershed assessments is to accelerate water quality improvements by focusing efforts in high priority areas. Specifically, subwatershed assessments are a tool used to identify the most effective urban stormwater conservation practice by location.
It is critical to train new staff, create modeling protocols for new BMPs, refine and calibrate models, and test ever-advancing modeling applications. The Metro Conservation District?s (MCD) Sub-Watershed Analysis (SWA) program provides these capacity-building services and unites efforts across 11 SWCDs. MCD proposes to analyze an additional 15 subwatersheds. The analyses will identify the location and estimated cost/benefit relationship for BMPs, evolve with new technology, and share discoveries metro-wide.
This project will replace a conventional 32 foot wide neighborhood street with a narrowed 22 -24 foot wide street that will include rain gardens, sidewalk, and boulevard trees. North St. Paul is using the term Living Streets to describe a new type of street that will eventually replace most of the city's existing streets. Living streets are narrower and have less pavement than existing streets. Reducing the width of existing streets reduces construction costs and assessments to residents. It allows room for the installation of rainwater gardens to treat stormwater.
Little Lake Johanna is not meeting state water quality standards due to excessive phosphorus. The Rice Creek Watershed District, in partnership with the City of Roseville, will improve the water quality of stormwater runoff into Little Lake Johanna through installation of an iron-enhanced sand filter. The Oasis Pond Iron-Enhanced Sand Filter Project will annually remove approximately 34 pounds of phosphorus from runoff to Little Lake Johanna annually. This is equal to nearly 20% of the needed load reduction as established by the Southwest Urban Lakes Total Maximum Daily Load Study.
The glacial geology of Ramsey County includes many layers of impermeable and semi-permeable material that can protect aquifers from contaminated waters. Many municipal public supply wells exist to draw water from these aquifers to supply thousands of consumers on a daily basis. Unfortunately, abandoned/unused wells also penetrate the protective layers of glacial material and can "short-circuit" the natural protection our glacial geology can provide allowing unfettered movement of contamination to even deeper aquifers below the ground.
Ramsey County, the most densely populated county in Minnesota, generates high levels of contaminated runoff from its impervious surfaces, which can have damaging effects on both surface water and groundwater. Concerns arise when these contaminants drain into abandoned and unused wells, threatening the quality of groundwater, especially in drinking water supply areas, wellhead protection areas, or groundwater recharge zones.
Ramsey County has 3,500+ acres tied to 358 faith organizations and 304 schools. On average, these properties contribute 1 billion gallons of stormwater runoff, 3,000 lbs of phosphorus, and 1,000 tons of sediment to our local water bodies. The Ramsey Conservation District (RCD), working with community partners and Watershed Districts/Water Management Organizations, will install 6-12 stormwater best management projects that will help protect and improve water quality of surrounding lakes.

Capitol Region Watershed District (CRWD), in partnership with the City of Roseville, will construct a volume reduction/capture-reuse irrigation facility below the Upper Villa Park Softball field in the City of Roseville. This project will protect Lake McCarrons and the Villa Park Wetland System (VPWS) by reducing runoff volumes and the pollutants associated with urban stormwater such as Total Phosphorus (TP), Total Suspended Solids (TSS), heavy metals, and petroleum products among others.
Capitol Region Watershed District is partnering with St. Paul Public Schools to implement a variety of highly visible Best Management Practices at Central High School that will improve the quality of stormwater discharged to the Mississippi River. A tremendous amount of sediment is discharged from the school annually due to the large impervious areas and lack of vegetation. Implementing the projects will reduce sediment by 86% and phosphorus by 90% over the target area annually.
The Rice Creek Watershed District (RCWD) will create a web-based, mobile-compatible public drainage system inspection and maintenance database. This database system will enable District staff to create and track maintenance requests and inspections from the field, including Geo-referencing locations requiring repair via a mobile device. The system will greatly reduce the time required to identify and log each maintenance request, enabling staff to inventory more miles of public drainage system yearly thereby identifying erosion problems more efficiently and thoroughly.
The Ramsey-Washington Metro Watershed District (District) has determined that large impervious sites (like churches, commercial sites, and schools) are more economical for stormwater management retrofit projects than distributed small projects along roadways. Analysis of the watershed land use indicates that large impervious sites are typically commercial properties (primarily retail), churches, and schools. The District began assessing church sites for retrofit opportunities in 2013 and will continue this effort in 2014.
This project will reduce phosphorus loading from the watershed tributary to Silver Lake. The project includes a combination of structural water quality improvements in the SLV-10 subwatershed north of the lake, retrofits (including iron enhanced sand filtration) to the Silver Lake bioretention basin, small scale best management practices (BMPs) throughout the watershed, and educational signage in Joy Park. The elements of this project will reduce phosphorus loading to Silver Lake by a combined 15 pounds per year or 40% of the current watershed load.
Wakefield Lake is in the Ramsey-Washington Metro Watershed District (RWMWD) and is impaired for excess phosphorus. Through the Wakefield Lake TMDL process, implementation activities have been identified which include partnerships with the City of Maplewood to install BMPs in the watershed to directly benefit Wakefield Lake. RWMWD has researched, monitored and field tested the use of spent lime for stormwater quality treatment.
The Highland Ravine is a large bluff area in central St. Paul that has become highly eroded due to hydrologic changes associated with urban development. During rain and snow melt events, water and sediment moves down slope onto private residential properties causing significant flooding and sedimentation. In addition, sediment-laden water from the gullies goes into the St. Paul storm sewer system which discharges, untreated, directly to the Mississippi River.
Bald Eagle Lake is a popular recreational lake known for its fishery on the Metropolitan Council's Priority Lakes List. The lake is negatively impacted by excess nutrients and restoring its water quality is a local priority.
This project will collect stormwater runoff from an approximately 900 acre area and re-use it to irrigate an existing golf course. This innovative project will provide a multitude of environmental benefits for Bald Eagle Lake including significant runoff volume reduction, groundwater recharge and phosphorus load reduction.
Capitol Region Watershed District will partner with local organizations and private landowners to implement a variety of cost-effective Best Management Practices in the East Kittsondale subwatershed. The urbanized condition of the 1,860 acre subwatershed results in an estimated 1,500 pounds of phosphorus, over 470,000 pounds of sediment, and significant concentrations of bacteria associated with that sediment being sent untreated to the Mississippi River each year. Those pollutants have contributed to several impairments within the river.
