Transportation System Plan 2018-2038

spacing were the prim ary factors used to evaluate st reet classifications, tem pered by the constraints of existing developm ent patterns. Recommended Street Functional Classifi cation System and Street Standards Figure 5-2 in the body of the TSP illustrates the recom mended functional classification sy stem within the Medford UGB. Also included in this section are propo sed standard cross-sections the new minor arterial and m inor collector street classifications, as well as industrial streets and com mercial streets (see Table H- 3). For reference purposes, the recently adopted st reet designations and streetscape standards for the downtown core are of Medford are also incl uded in this Appendix in Table H-4. Major Arterial 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 below under the “Minor Arterial” heading. Exam ples of m ajor arterial streets under City jurisdiction include Biddle Road, Crater Lake Avenue south of Delta Wate rs Road, and McAndrews Road west of Crater Lake Avenue. Street design standards proposed for m ajor arterials ar e outlined in Table H-3 and include a 70-foot paved width with four 11-foot travel lanes (two in each direction), a 14-foot raised center m edian (with left turn channelization where appropriate), and two 6-foot shoulder 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. Table H-5 sum marizes all proposed changes to the City’s existing functional classification sy stem . As indicated in this table, the alignm ent of Highway 238 has been redesignated from McAndrews Road to a newly constructed highway segm ent between Highw ay 99 and Sage Road, and then westerly along Rossanley Road to the western edge of the UGB. Wh ile designated as a state highway , this street should function as a m ajor arterial within the Medford UGB. In addition, the proposed new ramp system between Biddle Road and Highway 62 that are part of the North Medford Interchange project should also be designated as m ajor arterials. Other changes to m ajor arterial status include d esignation of the newly cons tructed connection between Highway 99 and Central Avenue (constructed as part of the Big “X” project), Center Avenue from Stewart Avenue to a point just south of Garfield Avenue, and Delta Waters Road from Highway 62 to Crater Lake Avenue. Center Avenue in this segment currently serves as a m ajor access route into the South Gate shopping center and will eventually connect with Garfield Avenue and is expected to serve major traffic volum es around the new South Medford in terchange. Delta Waters Road has a widened cross-section approaching Highway 62 to accom modate turning m ovem ents and through traffic heading for the com mercial developm ent on the west side of Highway 62. Minor Arterial 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 m edian, two 5- foot bicy cle lanes, two 5-foot sidewalks, and two 10-f oot planter strips. No on-street parking would be perm itted along a m inor arterial street. H-7
