Black Mountain Road CPA

Black Mountain Road CPA

A request for a GENERAL PLAN AMENDMENT to Figure LU-2, Land Use and Street System Map in the Land Use and Community Planning Element of the General Plan to change the street system classification of a segment of Black Mountain Road from Prime Arterial to Major Arterial; a COMMUNITY PLAN AMENDMENT to the Rancho Pefiasquitos Community Plan Circulation Element to reclassify the same segment from a 6-lane Primary Arterial to a 4-lane Major; and a COMMUNITY PLAN AMENDMENT to the Black Mountain Ranch Subarea Plan amending the Transportation Phasing Plan to remove the requirement to widen Black Mountain Road to a 6-lane Primary Arterial and add the project design feature and three traffic mitigation measures, identified below. The approximate 1.3-mile segment of Black Mountain Road to be reclassified would occur between Twin Trails Drive on the north to the southern community boundary adjacent to the Los Penasquitos Canyon Preserve. The project also includes a design feature to restripe the segment of Black Mountain Road between the SR-56 westbound ramps and SR-56 eastbound ramps to increase the northbound to westbound left-turn pocket storage and improve the flow of northbound traffic. To accommodate this restriping on the overpass, the roadway north of the overpass bridge would need to be widened for northbound traffic. The widening would extend approximately 0.15 mile from the SR-56 westbound off-ramp to the first commercial driveway to the north of the overpass. In addition, the following three mitigation roadway improvement measures are included as part of the project and analyzed in full detail through the Environmental Impact Report: MM-TRA-1 would require the installation of a traffic signal at the intersection of Sundance Avenue and Twin Trails Drive; MM-TRA-2 would require construction of a continuous auxiliary lane on eastbound SR-56 between Camino Del Sur and Black Mountain Road; and MM-TRA-3 would construct an additional on-ramp lane at the Rancho Pefiasquitos Boulevard/SR-56 westbound on-ramp. Implementation of the project would subsequently require amending the Rancho Penasquitos, Black Mountain Ranch, and Pacific Highlands Ranch Public Facilities Financing Plans (PFFPs) to remove the requirement to widen the project roadway to a 6-lane Primary Arterial and to add the project design feature and three traffic mitigation measures. At such tJme the Public Facilities Financing Plans are updated for the Rancho Penasquitos, Black Mountain Ranch, and Pacific Highlands Ranch communities, any changes to reflect the project and mitigation measures adopted by the action, would be incorporated, The Pacific Highlands Ranch requirement to widen the project roadway to a 6-lane Primary Arterial is outlined in Table4B-14, which is included in the Pacific Highlands Ranch Subarea Plan Master Environmental Impact Report. Upon certification of this Environmental Impact Report and approval of the General Plan Amendment, Community Plan Amendments, and the Black Mountain Ranch Transportation Phasing Plan amendment, MM-TRA-1 through MM-TRA-3 would supersede and replace widening the Black Mountain Road to a 6-lane Primary Arterial previously Identified in the Pacific Highlands Ranch Subarea Plan Master Environmental Impact Report. This Environmental Impact Report, which analyzes the removal of the existing Black Mountain Road 6-lane Primary Arterial designation for the project roadway from the Rancho Penasquitos Community Plan, the addition of the project design feature, along with the future implementation of three mitigation measures, could be relied upon for this future update to the Public Facilities Financing Plans. The site is not included on any Government Code listing of hazardous waste sites.
