How About This Instead of a Car Wash?

Update: More on How to Help Glen Echo Ravine

To help us oppose the zoning request discussed in the previous blog post please contact your City Council Member as soon as possible indicating your opposition to the zoning change for 2725 North High St., the old White Castle location built on Glen Echo Ravine and Run.

The rezoning application is being heard by both the Clintonville Area Commission and the University Area Commission as the property in question crosses the boundary between the districts – it is literally on top of the Ravine and Run. The CAC and UAC will send their recommendation to the Development Commission which makes a final recommendation to City Council Members who will decide on the request for a zoning change.

If you are taking time to write to the Clintonville commissioners, copy all the councilmembers too; its never to soon to write them.

Updated Urban Arboretum Tree Walk Maps


We have updated our two Arboretum walk maps, and digital copies are available here at the blog (in this posting and at the Maps tab above). A new printing of the maps will happen in the future, but for now only old versions of the walk maps are available on paper at the Arboretum kiosk.

For the time being, you can print the new maps yourself – legal size or tabloid. The latter, in color, costs a few bucks at a copy shop.

We added a few species of trees, replaced a few markers, placed the markers in Glen Echo Park, removed a few (now dead) trees from the routes, and added some additional information to each map; the color of the tree symbol indicates if it is newly planted or mature, and the orientation of the symbol shows which direction the tree can be found from the walk.

Please contact John Krygier ( if you have any additional corrections or comments on the maps.

Until next time!
