Original concernWe are “always” asked for comments after the planting fails to meet the original design intent.

When should we try to intercede?

Some university constraints

LEEDOhio State will be carbon neutral by 2050

Let’s consolidate academic programs

Campus should be pedestrian

Columbus mandated to deal with

stormwater and water quality

No net gain in academic space

We have an inventory….

When should we intercede ?

Results• Report now appended to development plans

• OSU will try to move plants smaller than 8 inch

• Will consider trees greater than 22 inch when siting buildings

Will it be easier to find such sites?
