PROJECT GOALS Our goal for this section of the site is to mitigate flooding in vulnerable areas while making the route more friendly to multi-modal transportation. We hope to contribute positively to the existing sense of community in the Palo Verde neighborhood by cultivating opportunities for outdoor interaction. We especially hope our design encourages increased cyclist and pedestrian use in a safe environment.

SHADE STRUCTURE SEATING I think shade trees are very important
WATER FOUNTAIN
MURAL
DOG WASTE DISPOSAL BICYCLE RACK
Right now I tend to walk that route more than bike it, but if it felt safer for biking I would probably use that mode of transporation more
I think Iâ&#x20AC;&#x2122;d be more likely to bike even north of Grant if this part of the route were nicer
Any shade is welcome (trees along the route)
BICYCLE TIRE PUMP I've only walked this route (variations) when I've had bicycle flats. Those times seating was most important. The flats have always been at night. If they'd been on a summer day, shade would have been a priority
PICNIC TABLE

What is your first pick for an element in a community space?
mural seating bicycle rack tire pump dog waste disposal picnic table
We donâ&#x20AC;&#x2122;t ride bikes much, but have begun to ride more frequently. A bike path as you are envisioning would encourage us to bike more frequently.
