Engineering > NPDES Permit Code Amendment (2016)

Adopting the Deparment of Ecology 2012 Stormwater Management Manual for Western Washington as amended in December 2014 (the 2014 Manual)

Proposing amendments to various sections of the Poulsbo Municipal Code in order to incorporate Low Impace Development (LID) principles and best managment practices and to address additional NPDES Permit and programmatic revisions


The Washington State Department of Ecology (DOE) National Pollution Discharge Elimination System (NPDES) Stormwater Permit issued to the City of Poulsbo requires the City to adopt the 2012 Stormwater Management Manual for Western Washington (as amended in December 2014) and amend appropriate sections of the Poulsbo Municipal Code to require Low Impact Development principles and best management practices to be the preferred and commonly-used approach to site development. The adoption of the 2014 Manual and amendments to the PMC regarding LID must be completed by December 31, 2016.

The 2014 Manual represents a shift in the development process which puts an emphasis on protecting areas which are well suited to handling stormwater. The 2014 Manual requires that all projects shall complete LID feasibility analysis and implement LID best management practices to the extent feasible. The primary LID principles and BMPs to be incorporated are: (1) Measures to minimize impervious surfaces; (2) Measures to minimize loss of native vegetation; and (3) Other measures to minimize stormwater runoff. Conventional stormwater management has led to large storm facilities in one location; the 2014 Manual will result in more numerous but smaller facilities which may look more natural. Installation of rain gardens on individual lots, bioretention areas near parking lot islands, pervious driveways, and infiltration areas will take precedence over the use of conventional systems. The purpose of the code updates is to remove barriers to LID implementation within City codes and standards. Some LID features and facilities are not supported by staff, for example pervious public roadways, due to a number of reasons including maintenance and safety issues.

In preparation for the amendment package, the City completed the following:

  • Attended trainings offered by DOE and Herrera Environmental Consultants
  • Retained the services of Sealaska Environmental to assist the City with the LID Code Amendments
  • Assembled internal team and met periodically over the past 14 months
  • Reviewed extensively “Integrating LID into Local Codes: A Guidebook for Local Governments.”
  • Utilized “Low Impact Development Code Update and Integration Toolkit” prepared by Department of Ecology
  • Completed recommended DOE LID Review Form/checklist to identify gaps



Six municipal code sections and portions of the City construction standards were identified as part of the LID code review process. In general these amendments and revisions serve to allow LID and clarify where and what type of facility is acceptable. In addition, some non-LID stormwater code revisions to PMC 13.16 and 13.17 are included which provide clarifications, procedural revisions, and compatibility with the current NPDES Permit.

A summary of all amendments is in the following table. The full package should be reviewed for specific revision and amendment language.
