to serve increased intensities planned in adopted land use Elements of their General Plan. In the event that such intensities are decreased, and reduction in the level of facility then is still feasible in view of rights of way then acquired, planning, design, engineering and construction then completed and financing commitments made, such fee also will be re- evaluated. The majority of the length of corridor alignments fall within relatively undeveloped areas of the County. Exceptions to this are either end of the San Joaquin Hills Transportation Corridor and the central segments of the Foothill/Eastem Transportation Corridors. Each corridor traverses areas of hilly terrain. A majority of the areas traversed by the corridors is zoned Planned Community with tentative tracts in various stages of approval. An alignment was selected by the Board of Supervisors for the San Joaquin Hills Transportation Corridor on November 28, 1979 and the northwesterly segment of the Foothill Corridor on May 25, 1983. More detailed engineering work is currently underway on the San Joaquin Hills Transportation Corridor to refine the selected alignment and determine right -of -way requirements. Similar detailed engineering is also in progress for the northwesterly segment of the Foothill Transportation Corridor. Alignment selection studies also are underway on the Eastern Corridor and the southerly end of the Foothill Corridor between about Oso Parkway and 1 -5. It is proposed that all corridors will eventually be added to the State Highway System. State legislation (AB 86) has been signed into law which redescribes State Route 73 (Corona Del Mar Freeway) to include the San Joaquin Hills Transportation Corridor. Legislation (SB 2048 and SB 2049), Chapters 1363 and 1364, respectively, of the Statutes of 1988 also have been enacted which designates the Eastern and Foothill Transportation Corridors as State Routes 231 and 241, respectively. IV. ESTIMATED COSTS The construction costs include estimates for all corridor grading and general travel lane improvements including bridges, structural section, interchanges, partial landscaping, and arterial highway realignments dictated by the corridor alignments. The cost of grading general High- Occupancy Vehicle (HOV) lanes is included but not the cost of HOV structural section, bridges, median barriers or special access ramps. It is intended that implementation of any transit guideway or HOV facilities, if needed, would be provided from other funding sources. Other costs included for both Corridors include engineering design, administration, construction inspection, right -of -way acquisition and some financing costs. It is proposed that developers will dedicate the majority of right -of -way for the transportation corridors. The cost estimate includes a cost for the portion of the right - of -way which would exceed a standard major arterial highway constructed along the corridor alignment excluding slope easements. The portion of right -of -way 223512_2DOC
