Submission Requirements

POSEIDONOnline electronic submissions must contain all required information and attachments for a review. If any information or required attachements are missing the submission will be rejected. No partial applications will be accepted.

Construction Drawing (CD) Checklists - CD Checklists are required by Water Resources in order to commence the application review process.

  • The E-CD must be submitted first, before a CD Checklist can be submitted.
  • A CD identification number (CDID) is assigned when an E-CD is submitted via VISTA.
  • The CDID is required to submit the CD Checklist via POSEIDONOnline. Once the CDID has been received by the applicant, proceed with the submission of the CD Checklists.

Stormwater Management Reports (E-Stormwater) – All E-Stormwater submissions must contain the full report with all required checklists, information, and stamps.

  • E-Stormwater reports are submitted directly via POSEIDONOnline.
  • If an applicant is submitting both the E-CD and E-SWMR concurrently, the E-CD must be submitted first.
  • If the E-CD is in circulation and the E-SWMR is being submitted at a later date, there is the ability to synchronize the E-CD to E- SWMR submission. The same applies if the Subdivision Stormwater Management Report is already in circulation and an E-CD is being submitted at a later date.

Amendments to Subdivision Stormwater Management Reports and Private Site Stormwater Management Reports.

  • Amendments to Subdivision and Private Site Stormwater Management Reports can be submitted to Water Resources via POSEIDONOnline using the Revised Final E-Stormwater Report process.
