Stormwater Standard Plans (SWSP)

Stormwater Standard Plans were prepared by the Salinas Permit Center, Community and Economic Development, and Public Works Departments, based on the Low Impact Development Initiative (LIDI) Standard Details, and City of Portland Stormwater Management Manual Typical Details. They are to be used in conjunction with the latest edition of the City of Salinas Stormwater Development Standards (SWDS) and the latest edition of the City of Salinas Standard Specifications, Design Standards, and Standard Plans.

Designers must consult with their project  geotechnical and civil engineer for review and use of these Standard Plans, clearances to structures, need for/extent of liners, subdrains, storm drain connections and similar appurtenances. Regardless of site infiltration rate, all projects will be required to filter stormwater on site using biofiltration methods (Post-Construction Best Management Practices or PCBMPs), with infiltration through underlying soils being the preferred method. Every effort shall be made, to the Maximum Extent Practicable (MEP), to infiltrate stormwater on site unless alternative means are approved in accordance with the City’s NPDES Permit requirements.

PDFs of signed SWSPs should be used for plan submittal. 

Note: All .dwg files are AutoCAD and need to be opened with AutoCAD to be accessible.
