Goals for Tonight’s Meeting
•Hear and discuss member city issues and suggestions
•Answer questions
•Get input on your priorities
Member Cities• Brooklyn Center (WM)• Brooklyn Park (WM)• Crystal• Maple Grove (WM)• Minneapolis• New Hope• Osseo (WM)• Plymouth• Robbinsdale• Champlin (WM only)
Management Planning
•First Generation Plan, 1990-2002: focus on water quantity, preventing flooding
•Second Generation Plan, 2003-2012: focus on water quality, education and outreach
•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
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
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

Water Quality Goals
•Improve water quality to meet state standards in these lakes:▫Schmidt▫Bass▫Eagle▫Crystal▫Middle Twin▫Ryan
Meadow Lake, New Hope
Water Quality Goals
•Improve water clarity in other lakes by 10%
•Complete stream improvements on 30% of the length of Shingle Creek
Shingle Creek, Brooklyn Park
Groundwater and Wetlands Goals
•Increase infiltration to restore groundwater
•Protect existing wetlands
•Improve functions and values of wetlands where possible
Cherokee Drive wetland, Brooklyn Park
Operations and Programming Goals
•Operate within sustainable funding level•Continue to share in the cost of
implementation projects•Continue to seek out grants and other
funding sources•Operate a public education and outreach
program•Operate a monitoring program and
publish an annual Water Quality Report

cities
Next Steps
Revised Plan sent to Board of Water and Soil Resources for review and approval (early 2013)
Comments and responses considered at a Public Hearing (late 2012)
Cities and review agencies have 60 days to submit comments to Commissions
