2. Stumbling Blocks
“For years we have been moving away from LID without even knowing it…we’ve moved to wider streets for better fire truck access and gone away from roadside ditches in favor of curb and gutter with storm sewers. “ Bill Robison, City of Tulsa

3. Getting in Our Own Way…
“Rain gardens could be considered a violation of our mowing ordinance if plants are more than 12” high.”

4. Getting in Our Own Way…
“Certain people in management are afraid pervious pavement will clog and become ineffective over time… “

5. Getting in Our Own Way…
“We don’t even allow bar ditch subdivisions anymore. Its curb and gutter by rule. And within the last few years we’ve had to add concrete bottoms to any channel, even roadside ditches.”

6. Motivating the Community
“It has been pretty surprising to me that not any of the businesses want some practically free green marketing….“ Jeff Bigby, City of Broken Arrow

7. Get Out of the Way Get Out in Front

8. Stepping Stones
“Good implementation of LID practices will require some modification to our ordinances and education on the part of citizen awareness as well as public officials.”
Bill Robison, City of Tulsa
Tools for Self Evaluation
EPA Water Quality Scorecard

10. Overview of Score Card Protect Natural Resources
Promote Efficient, Compact Development Patterns
Design Complete Smart Streets
Encourage Efficient Parking
Adopt Green Infrastructure Stormwater Management
Adopt Plans
Educate
Remove Barriers
Adopt Incentives
Enact Regulations

11. Getting Started
Review the scorecard to identify which agencies, depts, or personnel will be required for each section.
Convene appropriate staff to review their section
Collect existing ordinance and policies that will be necessary references for the scorecard.
Coordinate between appropriate agencies or departments.
Identify sections or questions to be prioritized for revision or update if needed.
Identify short-, medium-, and long-term goals and strategies for revising local policies to better support green infrastructure.

12. Example of
Scoring System

13. Protect Natural Resources/Open Space
Adopt Plans/Educate:
Identify and map critical natural resources
Steep slopes, high quality forest, drinking water watersheds
Remove barriers
Protection of natural resources qualifies for credit towards set- aside requirements
Adopt Incentives
Collaborate with land trusts to acquire critical resource areas
Adopt a transferable developments right program to provide incentive for preservation
Enact Regulations
To protect steep slopes and other sensitive lands
Create ag/resource zoning districts to preserve resources

14. Adopt Green Infrastructure SW Mgmt
Adopt Plans/Educate
Inform the public through education and outreach programs that green infrastructure can manage their stormwater
Create a training program for reviewers to ensure green infrastructure is applied effectively.
Remove barriers
Change or allow alternatives to building codes or other regulations to ensure that green infrastructure is legal, for example remove restrictions on downspout disconnection.
Adopt Incentives
Establish a “Green Tape” expedited review
Reduce stormwater utility rates for LID use

15. Open Space Protection Adopt Plans/Educate Remove barriers
Have a community-wide parks or open space plan
Remove barriers
Green infrastructure counts towards up to 50% of required set-aside/open space requirements
Adopt Incentives
Additional open space/set-aside credits provided for green infrastructure that is available for public/recreation
Enact Regulations
Adopt an open space impact fee to purchase passive open space that can assist in stormwater management

16. Promote Efficient, Compact Development
Question:
Are policy incentives in place to direct development to previously developed areas?
Goal:
Municipalities implement a range of policies and tools to direct development to specific areas
Why?
Municipalities realize a significant reduction in regional runoff and runoff management costs if they take advantage of previously developed sites rather than paving greenfield sites.

17. Street Design Question: Goal: Why?
Do locate street design standards and engineering practices encourage streets to be no wider than necessary? Are major streets required to integrate green infrastructure?
Goal:
Appropriate street widths allow narrower lanes for certain types of streets, reducing overall imperviousness. Formally integrate green infrastructure into standard construction.
Why?
Consistent project to improve or repair street provide opportunities to include green infrastructure retrofits.
