What was discussed about the variances?

The architects reworked the plans to meet the 70% glazing requirement. Units along Blount would have stoops to foster a more interactive feel.

There seemed to be expectation from the audience that there would be more commercial but the zoning code does not require a commercial element. The developers plan to modify the structure so the SW corner of the large buildings could be rented commercially.

The lot size and permeable paving* variances don't seem to be controversial, So it's down to the requirement of having 50% of the building abut the sidewalk. Personally, I prefer more variation on the setbacks. And on the corner you would need the space to accommodate ramps for a commercial tenant.

* the permeable paving variance is needed because the parking is in structures.

The plan is to use the existing driveway that runs behind the hospital as a riverwalk. It already goes under the Henley bridge, a feature I found very useful when biking to downtown.

As proposed, it appears the riverwalk will indeed be on top of the hill behind the development and not at water level. (Update here.)

The proposed elevated riverwalk appears to be a more practical, pedestrian/bicycle friendly alternative than the proposed riverwalk.

I would have expected the developer to follow the model of the Reedy River Riverwalk in Greenville, SC with retail along the riverwalk and residential above.

I believe the riverwalks could be connected to the west via ramps.

My prediction is that a connection to the east would involve an elevator. Bikes would need to be accommodated with a detour alongside the street system.
