810 Mission Avenue Project

The 810 Mission Avenue Project in Oceanside, California, involves the demolition of the existing NCTD Headquarters office building and surface parking lot to facilitate the construction of a seven-story mixed-use development. The proposed building will encompass approximately 326,647 square feet and feature 206 multi-family residential units, including five live-work units and 31 affordable units for low- and moderate-income households, along with 255 parking spaces. The project is managed by the City of Oceanside and is currently classified as a forecast under NAICS code 541360. The development has been granted a Class 32 Categorical Exemption under the California Environmental Quality Act (CEQA), as documented in a Notice of Exemption filed on November 20, 2025. Comprehensive technical assessments have been conducted to ensure environmental compliance, including studies on air quality, noise and vibration, biological resources, and cultural and paleontological resources. Infrastructure analysis confirms that existing offsite water and sewer pipelines are sufficient for the development. The scope of work includes extensive site preparation, remedial grading, and foundation work, with specific requirements for geotechnical testing and hydrology management. Final project acceptance is contingent upon meeting Section 3047(A) requirements and obtaining a Certificate of Occupancy.
