Notice of Intent to adopt a Mitigated Negative Declaration
Public Review Period July 13 - August 13, 2021


NAME OF PROJECT:  Central San Solar Panel Array

LOCATION: 4451 Blum Road, Unincorporated Martinez, Contra Costa County, CA

ENTITY OR PERSON UNDERTAKING PROJECT:  Central Contra Costa Sanitary District (Central San)

PROJECT DESCRIPTION: Central San proposes construction and operation a 1.75 megawatt solar panel array on approximately 8.2 acres of a 48-acre parcel (APN 159-140-042-7), which is already owned by Central San, and is referred to as the “Lagiss parcel.” 

The proposed solar panel array would be accessed from the northern end of Blum Road via extension of an existing private driveway. The proposed solar panel array would be encircled by a service road and perimeter fence. The existing surface area to be covered by the proposed ground-mounted solar panel modules is approximately 2.5 acres.  Combined, solar panel modules together with the service road and driveway, the area covered is approximately 4.0 acres of the 8.2 acres. The remainder (4.2 acres) is generally retention basins or aisle space between rows of panels, with only minor area being used for inverters; panelboards; main photovoltaic (PV) switchboard; step-down, pad-mounted transformer; and, intertie switchgear.

NOTICE IS HEREBY GIVEN THAT the Central Contra Costa Sanitary District, Contra Costa County, California, intends to adopt a Mitigated Negative Declaration for this project. This Mitigated Negative Declaration would be based upon a finding that there is no substantial evidence before Central San that the project will have a significant effect upon the environment. The reasons to support such a finding are documented by an Initial Study prepared by Central San. The Initial Study describes the impacts of constructing, operating, and eventually decommissioning the site sometime in the future.

The public review period for this Mitigated Negative Declaration is July 13 to August 13, 2021. A public hearing on this project are expected to be held before the Central San Board of Directors on September 2, 2021 at 1:30 p.m., at the Central San offices, 5019 Imhoff Place, Martinez CA. Following the public hearing, the Board will consider approval of the Mitigated Negative Declaration and the proposed project.

To obtain copies of the proposed Mitigated Negative Declaration with the Initial Study, go to: To review information used to prepare the Initial Study or to submit any written comments by 4:30 p.m., Friday, August 13, 2021, contact Central San’s Environmental Coordinator Russell Leavitt, at (925) 768-3430 or
