Maintenance Station Maintenance and Upgrades

Caltrans proposes routine maintenance at four (4) existing maintenance stations within San Diego County and Imperial County in State right-of-way. In addition, Caltrans proposes to decommission and dispose of existing aboveground double-walled storage tanks used for diesel fuel storage and replace them with new dual gasoline/diesel double-walled tanks.

Project Location

The proposed project is located at four existing California Caltrans maintenance stations within San Diego and Imperial Counties. Existing fuel tanks in the maintenance stations will be replaced and upgraded at the following locations:

San Diego County:

  • Station #5719 – 6050 Paseo Del Norte, Carlsbad
  • Station #5705 – 570 C Street, Chula Vista
  • Station #5713 – 40945 Old Highway 80, Boulevard

Imperial County:

  • Station #5725 – 200 South Palm Avenue, Brawley

Project Description

Caltrans proposes routine maintenance and fuel tank upgrades within each of the four (4) Maintenance Stations identified below in San Diego and Imperial Counties in State right-of-way. Specifically, the fuel tank upgrades include decommissioning and disposing existing aboveground double-walled storage tanks used for diesel fuel storage, and replace them with new dual gasoline/diesel double-walled tanks.

The routine maintenance at each of the four maintenance stations is typical maintenance activities and could include, but would not be limited to:

  • Pavement rehabilitation;
  • Rehabilitation, replacement, or upgrades to fencing;
  • Tree/vegetation trimming and/or removal;
  • Existing drainage ditch upgrades;
  • Painting or minor rehabilitation to appurtenant structures and utilities;
  • Maintenance and repair of maintenance station amenities such as buildings, wash out area, storage areas, and fuel tanks;
  • Security upgrades and preserving the integrity of buildings;
  • Material bunker upgrades/canopies for storm water compliance; and
  • Installation of solar canopies at the yards or on roofs.

Caltrans also proposes to decommission and dispose of existing double-walled aboveground storage tanks (ASTs) used for diesel fuel storage and replace them with new dual gasoline/diesel double-walled tanks (6,000 gallons diesel/4,000 gallons gasoline). Improvements may require the installation of new concrete foundations and/or pipe guard posts within the existing sites. As part of this work, minor excavation resulting in up to approximately 40 cubic yards of soil per site may occur. Surplus soil may be reused within the maintenance station facilities or disposed offsite if necessary. At the Carlsbad Maintenance Station additional work includes replacing asphalt concrete surfacing and installing concrete pads (6" thick). Work will occur in existing Caltrans right-of-way within developed, existing maintenance stations. No work will occur outside current maintenance station boundaries and construction work will comply with local, state, and/or federal regulations. Work at each site will consist of up to ten days for the four locations. Operations and maintenance post-project will be similar to current conditions.


  • This proposed Mitigated Negative Declaration (MND) gives notice to interested agencies and the public that Caltrans’ intends to adopt an MND for this project. This does not mean that Caltrans’ decision regarding the project is final. This MND is subject to change based on comments received by interested agencies and the public. Caltrans has prepared an Initial Study for this project and, pending public review, expects to determine from this study that the proposed project will not have a significant effect on the environment, because it will have no impact as described in the Initial Study with proposed Mitigated Negative Declaration.

The IS/MND is available for review and copying at the Caltrans District 11 Office at 4050 Taylor Street, San Diego, CA 92110 between December 29, 2021 to January 28, 2022 at Routine Maintenance for Four Maintenance Stations with Fuel Tank Upgrades Project.

Do you have any comments about processing the project with a IS/MND? Do you disagree with the findings of our study as set forth in the IS/MND? Would you care to make any other comments on the project? Would you like a public meeting? Please submit your comments or request for a public meeting in writing no later than January 28, 2022 to:

Caltrans District 11
