(Portland, OR)  --  A newly-issued report contends that Portland city leaders should begin fixing the city's streets now rather than later.  The City Club of Portland says the more street-repair projects are delayed, the higher the cost to taxpayers.  The committee that authored the report is recommending a five-cent gas tax and a commuter tax to help fund much-needed street-improvement projects.  Tomorrow's City Club Friday Forum will focus on the panel's report.
