The design guidance described here does not supersede any existing federal, state, or local laws, rules, or regulations. All projects remain subject to relevant statutes, such as the Americans with Disability Act and rules promulgated thereunder, the Zoning Resolution of the City of New York, the City Environmental Quality Review(CEQR), and appropriate reviews and approvals of oversight agencies. To best serve the public, designers should consider materials that are as universally accessible as possible when designing the public right-of-way.
