New Enhanced Stormwater Agreement and Manual

The Pierce County Planning and Public Works (PPW) Department has been notified that the Auditor will no longer accept stormwater agreements that do not strictly comply with their recording standards.

What is the issue?

In many cases the Maintenance and Source Control Manual (MSCM, Refer to Volume 1, 3.3.6 of the Pierce County Stormwater Management and Site Development Manual) created for the project includes elements like graphics, pictures, shading, hatching, and grayscale, that do not meet the monochromatic recording standards. Additionally, text height and recording margins are outside of compliance. Often to meet the requirement to provide a map in the MSCM, engineers reduce full-size plans to letter-size, making the plans illegible.

What is the solution?

PPW has created a downloadable PDF version of a Maintenance and Source Control Manual that meets the Auditor’s standards. Engineers complete the form fields, select the appropriate checklists and source control measures from this document, and can have confidence that they meet the Auditor’s standards.

Included in the document are examples and instructions for preparing the required stormwater system maps. Full-size site plans reduced to letter size will not meet the MSCM map requirement. Engineers will need to prepare a separate schematic map that meets the Auditor’s standards when printed on 8.5x11. The map is not intended to provide a high level of detail. The purpose of the map is to show the project area subject to the agreement and show the stormwater features requiring maintenance. 

How do I comply?

Prepare the MSCM using the new PDF. Use the correct stormwater agreement based on project type and ownership type (links in the PDF document and available on the Drainage Control Plan webpage.) 

Who can I contact if I have questions?

If you have any questions about this change, please contact L. Brandon Smith, PE, Engineering Manager, [email protected] or (253) 798-3716.
