The Event (Date yet to be determined)
Handing off to the next generation a healthier planet
This event will consist of a committed group of citizens, such as experience environmental activists, athletes, High School and Community College students, who are concerned about the potential impact of what the sea level rise could be for the SF Bay Area. It was inspired by the NOAA's Digital Coast Sea Level Rise Viewer.(For more background on this viewer see SFBCDC)
As the title suggests, the event will serve to mark the boundaries of a possible high-tide flooding area of marsh (See Saving the Bay)) and developed land in the immediate surroundings of the SF Bay, should CO2 emissions continue (see EPA predictions on future) on their current trajectory. These boundaries will be marked either with street sidewalk chalk, by writing on street pavement or sidewalk concrete, or with small flaglets that are stuck in the grass or dirt. Since this is a relay, runners will be running sequentially in time, each passing a baton to the next runner when their segment of the run has been completed. These meeting points will be known ahead of time. But the path ran by each will be up to the runner. The choice of this path will be driven by the requirement that they mark geo data points where flooding will occur - each point having associated information of its GPS coordinates, the water depth(zero being a high tide flood waters
edge).To assist the runner in choosing their path and locating these points along his/her run that are of interest, the baton will provide a electronic signal(LCD display and audio tone) indicating the depth of water or elevation.
The runner will mark this point as described earlier and press a button on the baton. This button will generate a signal from the baton, pass through the users phone, and transmitted up to the server. This data point will be immediately available to other participants to view from their phones web browser or app. Some will find this activity to be similar to map and compass orienteering.

The end point of the run will be in Sausalito where participants will gather to tell about their challenges, discoveries, reasons in the choices and maybe their interactions with interested people along the way.
The starting point will be determined by the number of participants and interest. If there are enough runners, this starting point could be as far north as Hamilton Field in Novato. With a smaller participation this might necessitate the run be scaled back to a starting point in San Rafael, either Marin Civic Center or Bus Depot. Below is a rough estimate of walking distances for various distances ( I used Google Maps to approximate distances and time to travel). The column “#” gives number of participants required to start here.

Time shown assumes walking full distance. But part will be bicycled most likely and presumably participants will be running, not walking. So duration is more like 4.5 hours
Good dates to choose for this event might be during times when many people are on the streets and at various festivities. A large projection or plasma screen(shaded at the back of a booth) might be set-up at one of these locations showing the current baton location.
Map Server: GeoServer with PostGIS containing ported data from ArcGIS via FME.
For simpler implementation, using Google maps and SVG overlays manually constructed by applying contour calculations on the TIFF downloaded from the Digital Coast SLR viewer. This TIFF has floating point values which when properly scaled give the elevation relative to sea level(but more examination of this later).
(It may be possible to view SLR maps directly(perhaps used in conjunction with ArcGIS javascript) in phone web browser but there is the challenge of placing the runner position graphic and also showing progressively the flood plane. )
For Video Camera:
For purposes of safety, logistical backup and amateur media coverage of the event, runners might be accompanied by a cyclist (on bike or recumbent trike)equipped with a cellular 4G connected video camera. Trikes are more stable for managing camera - for recumbent trike, indirect or linkage steering is essential since one handed steering is then possible.

High School and College Students:
It was suggest by a contributing member of the 350 Marin community that High Schools could be involved. An idea, I believe, that should be explored.

Along with activists, athletes and students as participants, people from the creative arts, like those who enjoy the dramatic arts, might want to participate. Whatever contribution brings public attention to the event and can lead to public action on the matter of concern, is a contribution that'll be welcome.

Imagine this trike encased by the body of a small boat - rudder on the back included. What character would you have sitting inside? What would be printed on the side of the boat?
