44 Have you thought about FREQUENTLY ASKED QUESTIONS

45 What about water quality? Water quality is a multi-faceted problem requiring range of solutions. Water Trails is an important component. Water trails complement the plans and projects of Watershed Management Authorities Water trails projects include water-quality improvements Proposed: Real-time water quality monitoring and reporting

46 What about water quality? Water quality is a multi-faceted problem requiring range of solutions. Water Trails is an important component. By inviting more people to the river, build generations of stewardship of the water. By tying economic development to water quality, increase pressure to improve water quality.

47 When will construction start? Like the paved trail network, this is something that will be built out over many years. Some regional projects are starting as early as this year Once funded, downtown projects are multi-year projects Estimated 2 years of regulatory permitting and compliance

48 How will we pay for it? This will have to a public-private partnership with many sources of revenue. Study is identifying state, federal, private grant opportunities Local governments capital improvement plans Private fundraising
