Hmm, but why limit it to the City?

Keep it here.

Can anyone create/teach me how to maintain a spreadsheet or documentation process that is publicly accessible online?
A google doc, perhaps?

The Wiki would be a good spot for that…

other people probably know how to do this better than I do, but if you put them on a map they can be annotated and exported… like the crash map or ToR map.

Look into GD FusionTables, or similar, and see if you can feed one from a form.

Fusion Tables is googledocs’ term for a spreadsheet, specific columns of which are specifically marked as a certain kind of data to be made into a visualization—in this case, geographic data which can be automatically plotted on a map. If you can combine that with a gd form (which automatically feeds into a spreadsheet), you can get a form > ss > map workflow that lets you (or “anyone”) fill out a form and plot these suckers on a map. you could probably also either export the map or the s/s with geocoded locationdata, too.

(there are probably ways to do this in Excel, with MapQuest, etc, but this is the one I’m (semi) familiar with.)

Here’s another lawsuit for ya Stu:

Martin Willett, ?the chief deputy county administrator, was seriously injured in June when the front wheel of his bike got stuck in a “drainage gap” on the Dodge Boulevard Bridge.

Yale Cohen dug up some relevant info on this topic worth sharing here. The city published a document in 2005, “Bicycle Facilities Guidelines and Policies”, containing recommendations for storm grates, apparently from PennDOT. See Figure 9.

PDF of the whole document

From Page 19:


Drainage Inlet Grates

Drainage inlet grates should be replaced with bicycle-friendly types. Grates that have bars that are parallel to the direction of travel can trap the wheel of a bicycle. Even grates with diagonal bars can be hazardous to bicyclists. These types of grates can trap a bicycle wheel if, when located on the corner of an intersection, the bars are oriented so that the slots are parallel to the wheel of a turning bicycle. If bicycle-friendly grates cannot be installed in a timely fashion, then steel straps should be welded to the existing drainage inlet grates at 4-inch intervals, center-to-center, perpendicular to the parallel bars. Drainage inlets should also be flush with the pavement surface.

So it would appear this document has been gathering dust on a shelf for nine years. Both the city and PennDOT had the right idea that long ago. It doesn’t take an engineering degree to figure out that the county would similarly be on board.

This message board thread is over five years old, with some of these grates untouched. I continue to be amazed these don’t garner more headlines. What is it really going to take to get the right departments to actually get out there and change these? Do we need a formal inventory? I would sooner spend any taxpayer money to switch out the ones we already know about instead of a formal inventory, and I don’t want to just do the city, just do one of 130+ municipalities at a time.

[That image took maybe 20 minutes to put together in Paint, adapted from here.]

Article NSFW btw. OUCH! I’ve had a couple grate crashes, but that takes the cake.
