The D.C. Council next week is expected to adopt legislation that could dramatically increase the number of parking spaces for bicyclists, a bill praised by the cycling community but criticized by property owners as oppressive overkill.

The measure mandates that all apartment buildings with more than eight units provide one bicycle parking space for every four residential units, demands that commercial landlords deliver enough bicycle parking to match at least 10 percent of the number of available automobile spaces, and requires the installation of bicycle racks at the Wilson Building for no less than 16 riders.
