12 STONES CONSTRUCTION, LLC is a small business specializing in civil infrastructure construction, with core capabilities centered on heavy and highway construction under NAICS 237130. The firm delivers turnkey solutions for public works projects including roadways, bridges, drainage systems, and earthwork grading, utilizing heavy equipment operations, pavement placement, and subsurface utility installation. Their technical expertise includes adherence to DOT specifications, stormwater management compliance, and construction quality assurance protocols. While no award history is available to confirm specific project types, the company’s primary NAICS classification indicates a focus on federally funded transportation and water resource infrastructure, suggesting proficiency in bid preparation, project scheduling, and regulatory coordination for public-sector civil works. No agency relationships can be inferred due to the absence of award data, and there is no evidence of prior engagement with federal, state, or local government entities. Similarly, no industry vertical specializations beyond general civil construction can be identified from the provided information. The company operates as a limited liability corporation (2L) headquartered in Kennesaw, Georgia, with no government-issued certifications on record. Its geographic footprint appears localized to the southeastern United States, with no indication of nationwide contracting presence. Positioned as a small, independently owned contractor, 12 STONES CONSTRUCTION, LLC likely competes for local and regional infrastructure contracts requiring skilled labor, equipment mobilization, and compliance with state transportation standards. Without certifications or documented past performance, the firm’s market positioning is grounded in operational capacity rather than specialized credentials or federal program participation.

Pastoria Solar Project by Pastoria Solar Energy, LLCThe Pastoria Solar Project by Pastoria Solar Energy, LLC involves the construction and operation of a solar generation tie line connecting the proposed solar facility to the existing Pastoria Energy Facility Lebec switchyard east of the project site. The project is anticipated to result in incidental take of the blunt-nosed leopard lizard, a fully protected and state-endangered species under California law, with permanent impacts to 0.14 acres and temporary impacts to 1.49 acres of its habitat. All impacts are confined to previously disturbed areas such as established dirt roads, minimizing new disturbances. To comply with state conservation requirements, the permittee will purchase 1.91 acres of Covered Species credits from a California Department of Fish and Wildlife–approved mitigation or conservation bank, ensuring full compensation for habitat loss in accordance with Fish and Game Code section 2081.15. A Minor Amendment No. 1 has been issued to adjust key conditions of approval, including extending the term of the Incidental Take Permit, delaying the deadline for purchasing mitigation credits, and providing additional clarity regarding the procurement and use of bank credits. The project is administered by Kern County as the lead agency, with oversight coordinated through the California Department of Fish and Wildlife, and all environmental compliance measures are designed to align with the California Endangered Species Act and applicable state statutes. The project remains on track to proceed under these adjusted timelines and enhanced mitigation assurances.
