Land Use and Zoning California 3 Minutes Read · published February 20, 2026 Flag of California

Overview

The City of Santa Clarita, California regulates subdivision street layouts through its municipal code and engineering design standards to ensure safe, connected, and constructible streets for new tracts and parcels. Developers must follow local design criteria, public improvement requirements, and the California Subdivision Map Act while obtaining tract or parcel map approvals from the Planning Division and Public Works. For the controlling municipal provisions and standards, consult the city code and the public works engineering documents listed below.[1]

Carefully review both the municipal code and the Engineering Design Standards before preparing map submittals.

Design & Approval Process

Street layout review occurs during tentative map and improvement plan review. Review topics include street classification, cross-section, right-of-way width, curvature, sight distance, utilities, drainage, sidewalks, and bicycle/pedestrian facilities. The City requires street improvements to meet its standard plans and specifications and to coordinate with regional circulation plans.

  • Submit tentative map and improvement plans to the Planning Division and Public Works for concurrent review.
  • Conform to required submittal timelines and revision cycles noted in the public review checklist.
  • Follow the City of Santa Clarita Engineering Design Standards and Standard Drawings for pavement, curb, gutter, driveways, and ADA ramps.[2]

Right-of-Way, Dedications & Improvement Agreements

The city may require dedication of right-of-way, utility easements, widening, turn lanes, or off-site improvements as conditions of map approval. Improvements are typically secured by an improvement agreement and a performance bond or other security instrument acceptable to the City.

  • Improvement agreements specify construction timing, bonding, and inspection responsibilities.
  • Bonds and security amounts are set per the City Engineer and project valuation.
  • Inspections by Public Works are required during construction to verify compliance with approved plans.

Enforcement of street layout and improvement requirements is administered by the City of Santa Clarita Public Works and Planning Divisions; code enforcement or the City Attorney may also pursue violations. Specific monetary fines, escalation, and administrative penalties referenced for subdivisions are not specified on the cited municipal pages and standards; see the cited code and contact the City for exact penalty schedules.[1]
