Standard Plans & Specifications

The “City of Napa Standard Specifications and Standard Plans” (City Standards) is a document that provides a summary and guide to key elements of the regulations and policies governing the design and construction of public improvements within the City of Napa.

The City of Napa requires design engineers, developers, and contractors to comply with the City Standards for projects within the City right-of-way and for City maintained facilities within easements. City Standards are intended to create uniformity of constructed infrastructure. Standardization of constructed facilities provides the City with the best value by minimizing long-term maintenance and operational costs.

The City Standards are organized by the following categories: Streets, Electrical, Drainage, Stormwater, Water, Parks and Landscaping, Street Trees, and Fire.

If you would like to purchase a hard-copy set of the City Standards you can do so at the City of Napa Community Services Building, 1600 First Street.
