LOSSAN Rail Corridor Improvement Projects, Environmental and GIS Services

Project Overview:

The LOSSAN Rail Corridor is the second busiest intercity rail corridor in the nation supporting commuter, intercity, and freight rail services. This 351-mile rail corridor stretches from San Luis Obispo to San Diego, connecting major metropolitan areas of Southern California and the Central Coast. Train operations on the line include Amtrak’s Pacific Surfliner; the Southern California Regional Rail Authority’s Metrolink and the North County Transit District’s COASTER and SPRINTER passenger rail services; and Union Pacific and BNSF Railway freight rail services. Each year, more than 2.7 million intercity passengers and 4.9 million commuter rail passengers (Metrolink and COASTER) travel the LOSSAN corridor. One in every nine Amtrak riders uses the corridor.

Scope of Work:

PanGIS staff have extensive experience working on rail projects providing both cultural resources and GIS services. PanGIS provided archaeological construction monitoring services for rail upgrade projects for NCTD and SANDAG (MCTC).  PanGIS staff perform archaeological construction monitoring and spot checks for three separate rail projects for SANDAG: San Diego River Bridge Double Track, Elvira to Morena Double Track, and Mid Coast Light Rail Transit. Staff completed extensive safety and project training. Monitoring logs and mapping with ArcCollector were completed on iPads. These projects require constant awareness of surroundings and movement between many different construction locations.

PanGIS provided ESRI based GIS mapping for the following LOSSAN rail projects: Sorrento to Miramar Curve Realignment, Second Track Project Phase 1 & 2, Elvira to Morena, Carlsbad Village double tracks, San Ysidro rail yard improvement, San Dieguito Bridge Replacement, and Del Mar Tunnel Alternatives Analysis projects. GIS services included collecting and processing data with high-precision GPS units, integrating aerial photos and engineering drawings from AutoCAD into a GIS geodatabase, and using them to produce high-quality report graphics.
