3. The Green Renaissance
It’s what the public wants
Cost of the Program: $32 Million Per Year
Benefits:
Stream Restoration, Urban Best Management
Practices, Community Greening, In-line Debris
Collection, Infrastructure Cleaning and Inspection,
Development Greening

4. Harder to implement without CSOs

5. River Valley Watersheds

6. Vacant Lands = SWM opportunities

7. How do we develop a
watershed
restoration plan with
active community
leadership for an
area of enclosed Watershed Community Collaboration
streams where the
environmental quality
and social fabric of
the watershed are
both impaired?

8. Restoration
projects should
be selected
with an
understanding
of their
interactions and
how they will
perform in
synergy to
impact the
watershed.

10. Neighborhood Assessment
• Neighborhood Source Assessment (NSA)
• Hotspot Site Investigation (HSI)
• Pervious Area Assessment (PAA)
• Streets and Storm Drains (SSD)
Two levels of BMP screening needed

11. Project Selection
• The presence of trees,
utilities (i.e., gas, electric,
water, sanitary sewer,
etc.), very compacted
urban soils, and a general
lack of space ruled out a
lot of projects and BMP
types…
– Only 35 sites were
investigated in detail
– The list of potential BMP
types was trimmed down to
about 5
Don’t forget public out-reach at
program and project scales
