Stormwater concerns

Proposed projects 5

What are “Projects”? (the lines on the map) • Stormwater infrastructure improvements • Green infrastructure • Additional inlet capacity • Pipe size upgrades where needed

What projects get built first? • Project prioritization reviewed at July Academy Meeting 7

Evaluation of prioritization criteria by stakeholders Score 0 10 20 30 40 50 60 Impact to structures Condition Number of people impacted Impact to water quality Impact to critical facilities Flood frequency Impact to major thoroughfare(s) Flooding of yards Depth of flooding Infrastructure ownership Impact to existing trees Impact to stream buffer Length of time its been a problem Green space protection Equity Multiple benefits Green infrastructure Capacity consciousness Maintenance 8

Prioritization tiers Impacted by the “critical design storm” • No downstream capacity issues • A Publicly owned system or proposed pipes in the right-of-way • Areas impacted by the “critical design storm” • Downstream capacity issues addressed in Priority A • B Publicly owned system or proposed pipes in the right-of-way • Areas impacted by the “25-year storm” • Publicly owned systems or proposed pipes in the right-of-way • C Remaining projects/private systems • D 9

How will projects be scheduled? • Prioritization scores will be developed based on: – Impact to major thoroughfares – Impact to critical facilities – Flood impacts to properties – Population impacted – Condition 10
