•Third Generation Plan, 2013-2022: focus on implementation and achieving outcomes

Overview of Past 10 Years: Successes• 13 lake nutrient TMDLs• Shingle Creek chloride

TMDL• Shingle and Bass Creeks

Biotic and Dissolved Oxygen TMDL

TMDLs evaluating

water quality

• Amount of pollutant load reduction necessary

• List of potential actions that cities can take

Implementation Plans for each TMDL

Overview of Past 10 Years: Successes

• Expansion of education and outreach programEducation

• Obtained $2.2 million in grants for projects and studies

Grants

• Calibrated hydrologic, hydraulic, and water quality models

Modeling

Overview of Past 10 Years: Areas Falling Short

•Minimal wetland management efforts beyond statutory requirements

•Minimal groundwater management

•Need to increase awareness by elected officials, advisory commission members

•Sustained citizen participation

•Reliance on volunteers to obtain lake water quality data

Problems and Issues

Maintaining & Improving Water Resources

13 lakes do not meet water quality goals

Shingle Creek and Bass Creek have low

dissolved oxygen and poor biotic integrity

Shingle Creek and Bass Creek are impaired by high levels of chloride

from road salt

Need to increase groundwater recharge

TMDLs

Regulations, Rules, and Standards

Upcoming state and regional

TMDLs

New water quality standards

Managing redevelopment

Impact of climate change

Unknowns

Evaluation and Communication

What is adequate progress toward improving water

quality

How do we influence behaviors that impact water

quality

How do we measure our

success

How should we provide information

to and get input from the public

Other Issues

Financial Stability

City budget limitations

More competition for grants

Unfunded regulatory obligations

How to fund financial

incentives for private property

Watershed Consolidation

•Historical basis for individual Commissions▫Level of development▫Difference in water resources

•Funding inequities if combined•Changes since Second Generation Plan

▫Distribution of tax capacity▫Increased activity in West Mississippi

•Now more equitable•County interest in consolidating WMOs

Goals andActions

Water Quantity Goals

•Continue to prevent flooding

•Increase summer flows in Shingle and Bass Creeks

Shingle Creek in Brooklyn Park

Increased Infiltration Requirement• Currently must

infiltrate ½ inch of runoff within 48 hours

• Proposed new standard is one inch of runoff in 48 hours

• Exceptions for clay soils, areas with soil contamination, or wellhead protection areas Bioinfiltration swale, Brooklyn Center

Proposed New Infiltration Credit•Get credit towards infiltration requirement•Provide soil management in turfed areas on

site•Decompact soil to 12” in depth•Amend top 8” with compost

All Land Uses Except Detached Single-Family Residential City Project Review Commission Project Review

cities

Implementation Plans

Next Steps

Revised Plan sent to Board of Water and Soil Resources for review and approval (early 2013)
