Challenges

Training contractors: RainWise has 54 contractors and

needs 154

Creating capital LID investment strategies for small

jurisdictions

Coordinating LID rebate strategies among jurisdictions

Recognizing and creating opportunities for LID

partnerships

Support to Phase II jurisdictions in the run up to 2016

permits

Next Steps

Expand health regulations allowing rain water harvesting (RWH) and treatment to potable as incentive to manage stormwater

Continue to identify support needs of jurisdictions in municipal permit implementation

Continue to leverage successful LID partnership models
