LA Metro Foothill Gold Line Light Rail: Glendora to Pomona Segment

The Los Angeles County Metropolitan Transportation Authority’s (LA Metro) Foothill Gold Line will be a 9.1-mile, four-station light rail line spanning Glendora to Pomona, one of the most heavily used transit corridors in Eastern Los Angeles County. Dudek is working with the construction contractor to facilitate the protection of environmental resources including sensitive wildlife and water quality throughout the project’s construction.

Project Facts

Agency: LA Metro

Client: Foothill Kiewit-Parsons JV

Location: Glendora to Pomona, CA

9.1-mile light rail

4 stations

The Challenge

LA Metro has prioritized connecting the San Gabriel Valley to key destinations to increase public transportation connectivity along one of the most heavily used transit corridors in Eastern Los Angeles County. State agency permit requirements include seasonal restrictions on work activities that may affect environmental resources. Additionally, the project must be completed before the 2028 Summer Olympics, which will take place throughout Los Angeles County.

The Solution

Dudek is providing construction compliance environmental monitoring within the most environmentally sensitive areas of the first nine-mile segment. Our biological and compliance monitoring teams are supporting the practical implementation of best practices to reduce environmental impacts during construction. Dudek experts are surveying for present sensitive resources, identifying site-specific appropriate mitigation practices, and monitoring to prevent impacts according to state agency permit requirements.

The Impact

Once completed, this project will add new stations to the Metro Gold Line system (currently referred to as the L Line) in the cities of Glendora, San Dimas, La Verne, and Pomona increasing ridership on the LA Metro system by an estimated 11,600 daily weekday boardings. It will connect important regional destinations like the LA County Fairplex, colleges and universities, historic downtowns, museums, regional parks, open space areas, and more. The extension will also provide a direct link between the L.A. Metro and Metrolink systems in Pomona, allowing riders to transfer easily from each system.

Next Project

Caltrain Peninsula Corridor Electrification Project

Caltrain’s Peninsula Corridor Electrification Project (PCEP) consists of electrifying a 51-mile stretch of existing track from San Francisco to San Jose by installing an overhead contact system (OCS) and associated power supply infrastructure. The goal is to improve Caltrain system performance and curtail long-term environmental impacts by reducing noise, improving air quality and lowering greenhouse gas emissions.
