Transportation System Plan 2018-2038

system , constraints that exist in the built and/or natural environm ent can be evaluated and incorporated into roadway planning and design without necessarily having to vary from adopted standards. However, in some locations due to historic developm ent pattern s, topographic features or other factors, deviations from the City ’s street standards should be accom modated. Figure 5-2 illustrates the functional classification sy stem within the Medford UGB. Changes from the City’s existing standard cross-section for functionally classified streets are shown in Table 5-6. This table includes the addition of standard cross-sections for the new m inor arterial and m inor collector street classifications. The following paragraphs describe the four m ost significant street classification categories: m ajor arterial, m inor arterial, m ajor collector and m inor collector. Major arterial streets carry heavy traffic volum es, most of it being traffic traveling through the urban area. Typically , they are equivalent to the Oregon Depa rtment of Transportation (ODOT) classification of principal arterial. For purposes of this TSP, it is assum ed that all existing designated arterial streets within the Medford UGB are m ajor arterials with the exceptions discussed in Appendix H under the “Minor Arterial” heading. Exam ples of major arterial streets under City jurisdiction include Biddle Road, Crater Lake Avenue south of Delta Waters Road, and McAndrews Road west of Crater Lake Avenue. Minor arterial streets also carry heavy traffic volum es, most of it traveling within the urban area, and they often connect two m ajor arterials. Minor arterials would differ from major arterials in that they are proposed to have a three-lane cross-section with a 48 -foot paved width and a total ROW of 78 feet. These dimensions would accom modate two 12-foot travel lanes, a 14-foot center left turn lane or median, two 5-foot bicycle lanes, two 5-foot sidewalks, and two 10-foot planter strips (see Table 5-6). No on-street parking would ty pically be perm itted along a m inor arterial street. Major Arterial Street design standards proposed for m ajor arterials are outlined in Table 5-6 and include a 70-foot paved width with four 11-foot travel lanes (two in each direction), a 14-foot raised center median (with left turn channelization where appropriate), and two 6-foot s houlder bikeway s (one in each direction). Five-foot sidewalks with a 10-foot planter strip would be require d, consistent with existing City code for arterial designations. No on-street parking would be perm itted or provided along a m ajor arterial street. Total required right-of- way (ROW) would be 100 feet. In Downtown and TOD areas the 10-foot planter strip would likely be paved with space designated for tree wells, providing for a 10 to 12-foot pedestrian facility in com mercial areas to create a “Main Street-like” environm ent. The newly constructed section of Garfield Avenue between Highway 99 and Holly Street is representativ e of the design standards for a Major Arterial as depicted in Table 5-6. Minor Arterial Alternative cross-sections for the m inor arterial c ould be provided through deve lopm ent and adoption of neighborhood plans, neighborhood circulation plans or Transit-Oriented District (TOD) plans where street speeds are expected to be lower. These plans would reflect the unique nature that a m inor arterial street could assum e as it passes through a pedestrian-friendly , mixed use developm ent area. The m inor arterial street cross-section in these unique areas could include different lane or sidewa lk configurations, and could potentially include on-street parking.
