Adding Bicycle Lanes <br />The city's policy is to require bicycle lanes on all <br />arterial streets and on all major collectors. Gener- <br />ally, the highest priority is placed on adding bicycle <br />lanes to arterials because of the need to provide a <br />safe means of bicycling on these streets. Bicycle <br />lanes are only infrequently provided on neighbor- <br />hood collectors, and almost never on local streets. <br />Because of the lower traffic volumes and slower <br />speeds of auto traffic on these kinds of streets, <br />bicyclists are able to share the space with cars <br />safely. Occasionally, particular conditions on a <br />neighborhood collector or local street might call for <br />striping bicycle lanes, for example to designate a <br />safe area for cyclists in locations where a great deal <br />of transition is occurring due to turn movements or <br />cross streets, or on streets that feature sharp curves <br />and turns. <br />Process: <br />Bicycle lanes are normally included in any new <br />construction or reconstruction of major streets <br />(major collectors or higher types) to urban stan- <br />dards. This process is described below. The city's <br />priorities for adding bike lanes on stn,ets that <br />already have curb and gutter is determined by <br />TransPlan and/or the city's Bikeway Master Plan. <br />Upgrading Streets to <br />Urban Standards <br />The city's policy is that all public streets have <br />minimal paved travel width, curbs, gutters, and <br />sidewalks. In practice, the highest priority is placed <br />on retrofitting arterials and major collectors to <br />urban standards, for reasons of safety and provision <br />of facilities for alternative modes of travel. <br />Neighborhood collectors generally have a lower <br />priority for upgrading, although each street is <br />evaluated on a case-by-case basis when the city's <br />Capital Improvement Program (CIP) is updated. <br />Process: <br />New streets, whether locals or major streets, are <br />required to be built to urban standards. Existing <br />local streets are normally improved only when the <br />property owners submit a petition indicating a <br />desire for the improvement and willingness to pay an <br />assessment. The priorities for upgrading existing <br />collectors and arterials to urban standards are set <br />in TransPlan (general phasing and priority) and <br />further determined by the city's Capital Improvement <br />Program, updated every two years. <br />Major Corridor Improvements <br />The. number of street segments that are likely to <br />undergo major improvements is a small proportion of <br />total street mileage. Generally, widening projects and <br />other major improvements are more likely to occur on <br />arterials, with a few examples on major col lectors. <br />Process: <br />Similar to upgrading to urban standards, decisions <br />about other major improvements are made initially in <br />the adoption of TransPlan. and subsequently in the <br />adoption of the city CIR Many of these projects will <br />require further "corridor studies" to determine the <br />scope of the improvements.. <br />New Street Mileage <br />A very small number of new arterial street segments <br />is planned, along with a larger mileage of major <br />collectors. Most new street mileage is built by private <br />developers, and is generally local. street mileage. <br />Some neighborhood and major collectors are also <br />expected to be built as part of new developments. <br />39 <br />
