Public Improvement Standards

The Public Improvement Standards are necessary in order to clearly define the minimum construction standard for new development in Watsonville. Staff has carefully examined all of the standards and has  simplified them. The revision’s focus is on designing construction standards which are economical to build, and eliminate redundancy and over-designed material specifications. 

New construction plans for public and private infrastructure improvements are reviewed by Community Development Department Engineering for consistency with these standards.
