This month Seattle lawmakers will start taking steps to rezone the University District. In a sign that City Council members want to get it right the first time, they plan to amend their proposal even before they introduce it.

The City Council announced a list of possible amendments to the U-District plan Friday.

The existing University District zoning proposal would allow for many more high-rise style buildings at about the height of the UW Tower. The plan would make the University District more dense, especially around the future light-rail station.

As part of the legislation, developers will need to build or pay for affordable housing units. That’s part of the "grand bargain" between the city of Seattle and developers.

Based on the new amendments, the City Council wants to require slightly more affordable units than they originally would have. For example, it would require 10 percent of units to be affordably priced, instead of 9 percent, as originally proposed.
