Better Site Design <br />• The Portland fire chief was amenable to streets as narrow as 18 feet with parking on one side in grid <br />pattern streets or on short cul -de -sacs. <br />• No citizen has charged that fire rescue time was impeded by skinny streets since the inception of this <br />program in 1991 (Bray, 1997) <br />One exception was noted with respect to long roads Leading to cul -de -sacs (e.g., 1500 feet); these streets <br />require two travel lanes for adequate fire vehicle access. The fire bureau therefore retained the right to <br />veto narrow streets on long cul -de -sacs. <br />In the City of Portland, the cost savings realized from narrow streets allowed the city to improve less - <br />developed portions of the roadway which, in turn, encouraged infill development. Infill development refers <br />to development or enhancement within existing urban areas as an alternative to developing surrounding <br />rural areas. <br />Figure 1.2: A Comparison of Queuing Streets vs. Traditional Streets [Source: Portland (0R) Office of <br />Transportation, 1994] <br />32 ' Roadway (2 Parking Lanes) <br />7' 1 9' <br />parking <br />lane I <br />9' <br />a <br />lanes <br />parking <br />I lane <br />0 <br />26 ' Roadway (2 Queuing Lanes) <br />7' I 12' I <br />7' <br />Queuing' <br />lane <br />4 <br />Moving <br />lane <br />Queuing <br />I lane <br />28 • Roadway (1 Parking Lane) <br />10' • 10' 8' <br />moving <br />1 <br />i <br />t <br />lanes <br />TIE <br />-I <br />parking <br />1 lane <br />20 • Roadway (1 Queuing Lane) <br />13' I 7' <br />4 <br />Moving <br />ane <br />Queuing <br />I lane <br />- 34 - <br />
