TRANSPORTATION CORRIDOR AGENCY - SAN JOAQUIN CORRIDOR

Home Browse Search

join the San Diego Freeway (I -5) between Avery Parkway and Junipero Serra Road near the City of San Juan Capistrano (see Exhibit I). It will be designed to comport with scenic highway standards and provide approximately six to ten general purpose travel lanes, with a median of sufficient width to accommodate future high - occupancy vehicle (HOV) lanes and special transit facilities, if required in the future. The central segment of the corridor will carry the greatest amount of traffic because there are a limited number of alternative parallel highway facilities. Traffic volumes on the south end of the corridor are lowest along the route as a result of countywide traffic orientation, which is generally to the north. Access to the corridor will be limited to approximately 12 grade - separate interchanges with arterial highways as well as provisions for future additional interchanges with arterial highways plus provisions for future additional exclusive interchange ramps for HOV lanes. Additional bridges may be required as the corridors cross substantial canyons and water courses. The EASTERN TRANSPORTATION CORRIDOR is currently shown as a set of alternative preferred alignments and included in the Transportation Element of the Orange County General Plan. The preferred alternatives will be studied further as the environmental review process continues. The FOOTHILL TRANSPORTATION CORRIDOR is an established alignment between the Eastern Corridor and a point northerly of Ortega Highway and a conceptual alignment between that point and the San Diego Freeway (I -5). As depicted on Exhibit I, the Eastern Transportation Corridor will intersect the Riverside Freeway (Route 91) between Weir Canyon Road and Gypsum Canyon Road extending southeasterly approximately 13 miles to a point southerly of the Santa Ana Freeway (I -5) in the Cities of Tustin and Irvine. The Foothill Transportation Corridor will originate at the Eastern Corridor between Santiago Canyon Road and Irvine Boulevard and extend southeasterly approximately 32 miles to the San Diego Freeway (I -5) below San Clemente in San Diego County. It is anticipated the Eastern Corridor will be a landscaped, grade separated scenic corridor which includes approximately six general purpose travel lanes and the Foothill Corridor, a landscaped corridor which includes four to six general purpose travel lanes with medians or other areas wide enough to accommodate HOV /Special Transit requirements if necessary. Access to the corridor will be limited to grade - separated interchanges with arterial highways plus provisions for future exclusive interchange ramps for HOV lanes. III. CORRIDOR PLANNING The level of facility planned in this report will support currently adopted land use plans of the County and Cities surrounding the corridors. In the event the Cities and County subsequently amend their existing General Plan Land Uses Elements, particularly in areas serving the Foothill and Eastern Corridors, those facilities may require adjustments in lanes to accommodate that growth. It is intended that the fee adopted under this program will be reevaluated if an additional level facility is needed 223512_2.DOC
