Changing dangerous places to walk, into walkable surfaces.
Would you like to see ditches* like this

which forces pedestrians onto roadway shoulder, turned into a walkable swale like this

where one could walk or wait more safely for the bus, while at the same time allowing for drainage of the street?

In the near term the Bureau of Environmental Services(BES) Ditches to Swales program has identified and put SW Shattuck, SW Hamilton, and SW Dosch on the top of their project list. E.g. if the ditch along the west side of SW Shattuck were converted to a walkable swale, there would be a walkable surface 2-3 feet wide along most of the length of SW Shattuck!
BES is holding off on SW Hamilton in order to coordinate with the SW Hamilton Halo LID project.
• Friday November 9th, 2007 D2S is "still waiting on funding decisions on our CIP project, of which ditch-to-swales is one component. Second, we do not yet have a BES engineer/designer assigned to the ditch-to-swale project. Since our field visit would focus on site-specific and designed related points, we want to have the designer present to hear everyone's questions and comments. We will schedule a meeting/field visit as soon as we know more about funding and have an engineer assigned to the project."
• Tuesday November 13th, 2007 - "We expect to know more about funding and getting a BES engineer/designer assigned to ditch-to-swales within the next month. I will email everyone in early to mid December with another update." - Shannon Axtell, City of Portland Bureau of Environmental Services, Watershed Services Group - Fanno/Tryon Team

*Please note: Originally this concept was called Swales to Trails; but the current more correct terminology is now Ditches to Swales. In Greg's model/proposal pictured above the surface would be covered by some low growing "forbes" that would help filter the water even more, in the current BES implementation the top surface is consists of pedestrian friendly sized rock.
