The City of San Juan adopted an official Subdivision Standard Design Manual that sets minimum engineering, design and construction standards for new public‑infrastructure projects (streets, drainage, water, wastewater, parking, traffic control, etc.) within the city and its extraterritorial jurisdiction. The manual‑ordinance, approved by the City Council in 2024, defines terms, outlines the development, submittal and plan requirements, and provides detailed tables and appendices for each type of improvement. It does not remove legal liability from engineers, developers or contractors; they must still follow all applicable laws and obtain the most current version.
