Traffic and Transportation
T-1a Prepare Traffic Control Plans. Prior to the start of construction, SCE shall submit Traffic Control Plans (TCPs) to all agencies with jurisdiction over public roads that will be affected by overhead construction activities as part of the required traffic encroachment permits. TCPs shall define the locations of all roads that will need to be temporarily closed due to construction activities, including aerial hauling by helicopter and conductor stringing activities. The TCPs shall define the use of flag persons, warning signs, lights, barricades, cones, etc. to provide safe work areas and to warn, control, protect, and expedite vehicular and pedestrian traffic. The measures included in the TCP shall be consistent with the standard guidelines outlined in the Caltrans Traffic Manual, the Standard Specifications for Public Works Construction, and the Work Area Traffic Control Handbook (WATCH). Copies of the TCPs shall be sent to the responsible agencies for review, including Los Angeles County and the cities of Lancaster and Santa Clarita and Los Angeles County.
TCPs shall also include measures to avoid disruptions or delays in access for emergency service vehicles and to keep emergency service agencies fully informed of road closures, detours, and delays. Police departments, fire departments, ambulance services, and paramedic services shall be notified at least one month in advance by SCE of the proposed locations, nature, timing, and duration of any construction activities and advised of any access restrictions that could impact their effectiveness. Provisions shall be ready at all times to accommodate emergency vehicles, such as immediately stopping work for emergency vehicle passage, short detours, and alternate routes developed in conjunction with local agencies. TCPs shall also identify all emergency service agencies, include contact information for those agencies, assign responsibility for notifying the service providers, and specify coordination procedures. Copies of the TCPs shall be provided to all affected police departments, fire departments, ambulance and paramedic services. Documentation of coordination with service providers shall be provided to the CPUC prior to the start of construction.
T-1b Restrict Lane Closures. To mitigate traffic congestion and delays during construction, SCE shall restrict all necessary lane closures or obstructions on major roadways, as designated by applicable County or City General Plans, associated with overhead construction activities to off-peak periods only. Lane closures must not occur between the peak hours of 6:00 and 9:30 a.m. and between the peak hours of 3:30 and 6:30 p.m., or as directed in writing by the affected public agency in the encroachment permit.
T-2 Prepare Construction Transportation Plan. To reduce the number of Project-related vehicles traveling on roads within the Project area, site construction workers shall be staged off site at marshalling yards or near paved intersections and workers will be shuttled to construction sites in groups in crew vehicles.
T-4 Avoid Disruption of Bus Service. SCE will coordinate with Santa Clarita Transit at least one month prior to construction to reduce potential interruption of bus transit services. SCE will also consult with the Saugus Union School District at least one month prior to construction to ensure construction activities are scheduled such that they will not disrupt school bus routes.
T-5 Provide Temporary Pedestrian and Bicycle Access. Where construction will result in temporary closures of sidewalks and other pedestrian facilities, SCE will provide temporary pedestrian access through detours or safe areas along the construction zone. Any affected pedestrian facilities and the alternative facilities or detours that will be provided will be identified in the Traffic Control Plan required pursuant to Mitigation Measure T-1a. Where construction activity results in bike lane closures, appropriate detours and signs will be provided.
T-6 Coordinate with Caltrans and the City of Santa Clarita to Avoid Conflicts with the Santa Clarita Cross-Valley Connector. SCE shall coordinate project design with Caltrans and the City of Santa Clarita to ensure that structures associated with the transmission line are not placed in locations that could block further widening or development of the Santa Clarita Cross-Valley Connector.
T-7 Repair Damaged Road ROWs. If damage to roads, sidewalks, and/or medians (including irrigation systems for landscaped medians) occurs, SCE will be responsible for ensuring repairs are implemented within two months of completion of construction activities at the affected location. Roads disturbed by construction activities or construction vehicles shall be properly restored to ensure long-term protection of road surfaces.
