Juneau's skyline may become taller and denser as changes to area zoning codes could mean more densely-built neighborhoods.
   
The Juneau Empire says (http://is.gd/IbAKHW) that recently-approved changes are meant to increase the availability of affordable housing in Juneau. The new rules may also alter the look and feel of neighborhoods.
   
The code allows for a significant increase in residential density. It also allows developers to build about 10 feet taller in certain commercial zones, reaching up 65 feet high in some mixed use zones.
   
The Juneau Planning Commission is updating its plan to guide future development.
