Corona Subdivision Plat and Street Standards Checklist
In Corona, California, subdivision plats and street standards govern how land is divided and how new streets and improvements are built and accepted by the city. This checklist explains the key documents, engineering standards, approval steps, inspections, and where to get official forms and technical standards. It is intended for surveyors, developers, civil engineers, and property owners preparing tentative maps, parcel maps, improvement plans, or public right-of-way work.
Key requirements and standards
Typical municipal requirements include a tentative map, final map or parcel map, grading and improvement plans, bonding for public improvements, and compliance with the city engineering standards and the California Subdivision Map Act. The City of Corona Planning Division reviews land-use and map applications while the Engineering Division reviews improvement plans and inspects public works construction.[1][2]
Design & Standards
Design must follow the City of Corona standard construction specifications, improvement plan checklist, street cross-sections, drainage criteria, sidewalk and curb requirements, and utility trenching standards. Check whether proposed streets will be public or private and verify pavement, slope, and ADA ramp specifications with the Engineering Division during plan check.[2]
- Tentative map application and exhibits
- Final map or parcel map and legal descriptions
- Improvement plans showing streets, sewers, drainage, and grading
- Bonds or guarantees for completion of public improvements
- Traffic control and sequencing plans for construction within the public right-of-way
Permits, plan check and inspection process
Submit complete plan sets to Planning and Engineering for coordinated review. Engineering issues plan-check comments, requires approved plans and bonds, and schedules inspections for street subgrade, utilities, curb/gutter, paving, and final acceptance. Contact the Engineering Division for submittal requirements and to schedule inspections during construction.[2]
