• Established through JPA

• 10 member communities

• 19 square miles

• Flows to Lake St. Croix

Collectively protect, manage and improve the quality of water resources in an efficient and effective manner.

Middle St. Croix WMO

3rd Generation Plan Update Stakeholder Feedback • Consider review triggers, rules, and goals of neighboring

watershed districts when appropriate to ease permitting difficulty for member communities.

• Consider wider range performance standards such as Minimal Impact Design Standards and implement when appropriate.

• Protect natural resources from development pressures.

• More clearly define reconstruction vs. new construction.

• Revise process for reviews for small projects

Middle St. Croix WMO

Integrating MIDS Into Local Ordinance

Advantages • Consistent with other communities

• When in ordinance, standards and credits are more transparent for developers (reduces confusion)

• Opportunity to review all ordinances to identify and consider conflicting ordinances and requirements

Challenge • Requires technical expertise and community staff time.

• Requires educating multiple groups (in each community) about MIDS

Integrating MIDS Into Local Ordinance

MIDS Accelerated Implementation Grant App • Build off lessons learned during the development of the MIDS

Community Assistance Package

• Work with up to 13 communities to integrate MIDS into local ordinance

• When in ordinance, standards and credits are more transparent for developers (reduces confusion)

• Opportunity to review all ordinances to identify areas where more flexibility could save time and money

• Opportunity to review

Integrating MIDS into Local Ordinance

“Algae Explosion in Lower River Inspires New Calls for Runoff Reduction”

Small storms (0.5 to 1.5 inches) are responsible for 75% of stormwater pollutants.

“Stormwater practices that

harvest, infiltrate, and

evaportranspire

stormwater are critical to

reducing the volume and

pollutant loading of small

storms”

0.5 to 1.5 inch storms are responsible for 75% of stormwater pollutants.

“Past practices…

have been

ineffective at

protecting water

quality in receiving

waters”

Stormwater 101

“…develop performance standards, design standards or other tools to enable and promote the implementation of low impact development and other stormwater management techniques….” (MN Statutes 115.03 subd. 5c)

MIDS Legislation, 2009

Stormwater 101

is a consistent, flexible and achievable stormwater management. The emphasis is on keeping the raindrop where it falls in order to minimize stormwater runoff and pollution* and preserve natural resources.

Minimal Impact Design Standards

What is MIDS?

*0.5 to 1.5 inch storms are responsible for 75% of stormwater pollutants.

Stormwater 101

What is MIDS?

Four basic components:

1. State-wide stormwater volume performance goal

2. User-friendly calculator to standardize (“credit”) for stormwater practices

3. Easy to follow “Flexible Treatment Options” for sites with restrictions

4. A model MIDS ordinance package

What is MIDS and how it is different

• Legislature gave funding to MPCA to create MIDS

• Work guided the process

• Met for 3 years

• Reviewed the science

• Moved decisions forward by consensus

Who Is In the Process of Adopting MIDS

• Metro Watersheds (highlighted orange)

• City of Owatonna

• City of Woodbury

• Chisago City, Lindstrom and Centre City in Chisago County

• Deerwood, Crosby and Irondale Township in the Crow River SWCD

• Stearns County, Watab Township

Currently Evaluating MIDS

• Brown’s Creek WD

• Forest Lake Comfort Lake WD

• Vermillion River Joint Powers Organization

How is MIDS Different Than Existing Req.?

• Consistent with other metro watersheds (level playing field) and achievable

• More flexibile than existing requirements

• Consistent credits for stormwater practices • Because:

• The Right people and organizations were at the table

• Complies with stormwater permits

• Based on science, analysis AND implementatoin experience

• MIDS will improve water quality


Why stakeholders are supporting MIDS

• Consistent stormwater design rules & standards

• Easier to implement at the local level

• Increased flexibility

• MIDS Calculator provides consistent credits for stormwater practices

• Right people and organizations were at the table–a meaningful stakeholder process

• Complies with stormwater permits

• MIDS is supported by science, analysis, experience, and input from many people and organizations

• Implementation will improve water quality

What is MIDS?


1. Stormwater volume performance goals

2. Calculator to standardize and quantify (“credit”) the benefits of LID BMPs

3. Design specifications for a variety of LID BMPs (continuing in Stormwater Manual update)


What are the Performance Goals?

Most Sites

• Retain on site 1.1” of runoff from new and/or fully reconstructed impervious surfaces

Linear Sites



Why are there different Performance Goals? Site restrictions might require flexible treatment options (FTO)

• Different performance goal if site has “restrictions” (including, but not limited to):

• zoning/land use requirements

• karst

• shallow bedrock

• slow-draining soils

• high groundwater

• contamination


What are the Performance Goals?

Most Sites

FTO 1: Clay,

etc.

FTO 2: Contam-ination

FTO 3


• Retain 0.55” of runoff from the new and/or fully reconstructed impervious surfaces AND

• Remove 75% of the annual TP load

• Achieve as much volume reduction as practicable AND • Remove 60% of the annual TP load

• Off-site mitigation

10% of New and Fully

Redeveloped Sites

Process: 1. Consultant Reviews and Redlines Ordinances

2. Meet with City Staff to Review and Adjust

3. Planning Commission Review and Adjust

4. City Council Review and Adjust

5. City Adoption of Final Ordinances

Outline the benefits and commitments of modifying local ordinances.


Next Steps

• Develop a timeline with City Staff

• Designate a City Representative

• Send City Attorney to Attorney Training on December 16. (City will be reimbursed $300 for billed time.)

• Develop a draft Workplan

• Formally Commit To Participate in the Process and Adopt MIDS into Ordinance

Outline the benefits and commitments of modifying local ordinances.


Process 1. Initial Meeting with City Staff and/or Local Officials 2. Invitation Letter to Participate in the Grant Project 3. Attorney Workshop Lead by MPCA Attorney 4. Planning Commission MIDS Overview Presentation 5. Council Presentation 6. Consultant Ordinance Review and “Redlines” 7. Ordinance Revision Review Meeting with City Staff

(modifications made based on staff feedback) 8. Ordinance Revision Review Meeting with Planning

Commission and Council

Why not just adopt by MIDS by reference?

Does the MIDS calculator replace stormwater modeling?

Will this be a barrier to redevelopment?

Will adoption of MIDS be more work for community staff/consultants?

How is this different from current requirements?
