Stormwater Site Plan Review Checklist:

Detailed Review

This checklist describes the requirements associated with each of the 10 minimum requirements

outlined in the Stormwater Management Manual for Western Washington, February 2005. All

projects meeting the thresholds in Volume I, Chapter 2, Figures 2.2 and 2.3 are required to

prepare one or more stormwater site planning documents for Municipality review. The applicant

must demonstrate and document compliance with each applicable requirement through the

appropriate stormwater site plan (see Minimum Requirement #1, and the applicable submittals

checklist associated with a given project type).

Minimum Requirement #1: Preparation of Stormwater Site Plans. (Volume I, 2.5.1)

Confirm the project has submitted each of the following documents where required:

Permanent Stormwater Control Plan

Construction Stormwater Pollution Prevention Plan (SWPPP) (aka Erosion and

Sediment Control Plan)

Off-site Analysis

Construction Plans and Specifications for stormwater facilities.

Minimum Requirement #2: Construction Stormwater Pollution Prevention

The Construction SWPPP addresses the 12 Elements of Construction Stormwater Pollution

Prevention as detailed in Volume II, Section 3.2. Each of the 12 elements must be considered

and included in the Construction SWPPP unless site conditions render the element unnecessary

and the exemption from that element is clearly justified in the narrative of the SWPPP. Project

requirements. The 12 elements are:

1. Mark clearing limits
