Rules Governing the Design and Construction of Private Sewers or Private Drains
Title 15 of the Rules of the City of New York Chapter 23 applies to Drainage Proposals to address the hydraulic adequacy of proposed private drains, construction plans for private sewers and private drains and permit applications to construct private sewers and private drains.
Local Law 96 amends the New York City Administrative Code to establish the North American Vertical Datum of 1988 (NAVD 88) as the city datum.
