Minor Site Minimum Stormwater RequirementsAPPJL2010
EDMONDS STORM WATER CODE SUPPLEMENT
6.0 Minor Site Requirements
Minor Site Projects must comply with Minor Site Construction Stormwater Pollution Prevention
Practices.
6.1 Minor Site Minimum Requirement - Construction Stormwater
Pollution Prevention Plan
All new development, redevelopment, and construction projects are responsible for preventing erosion
and discharge of sediment and other pollutants into the City's municipal storm drainage system and
receiving waters. For Minor Site Projects, a shorter Minor Site Construction Stormwater Pollution
Prevention Plan can be prepared.
The following BMPs must be applied:
For Sites with Clearing and Grading:
• Plan and implement proper clearing and grading of the site. It is most important to clear
only the areas needed, preserve vegetation, protect soils, and keep exposed areas to a
minimum.
• Re -vegetate, cover with straw, or otherwise stabilize all exposed soil as soon as possible.
• Locate any soil piles away from drainage systems. Temporary stabilization or covering of
soil piles must occur at the end of each work day or other best management practices
must be implemented to prevent discharges of soil or sediment to the City's storm
drainage system or surface waters or adjacent properties.
• Provide storm drain inlet protection within the project area and downstream as required
to prevent sediment and pollutants from entering the City's storm drainage system. Inlet
protection must be maintained throughout the life of the project and not cause any
discharge of sediment or localized flooding issues. All inlet protection must be removed
and properly disposed of immediately after project completion.
Additional Requirements for Underground Utility Projects
• Areas within the paved City right-of-way that have soil or sediment deposited during
construction must be swept or otherwise removed and properly managed at the end of
each work day, unless other arrangements have been made with the City's Engineering
Division.
• Water -tight trucks must be used to transport any saturated soils from the site.
• All contractors must a have a spill containment and clean up kit onsite at all times that is
compatible with the applicable pollutants
• All utility workers must exercise proper pollution prevention techniques during all
construction activities including the proper storage of any hazardous materials.

EDMONDS STORM WATER CODE SUPPLEMENT
De -watering shall be controlled per Element #10, Section 3.2.3, Volume II, of the Stormwater Manual.
All discharges into the City -owned storm system or water of the state shall be in compliance with ECC
7.200, Illicit Discharges. Sanitary sewer discharges must have the approval from the Edmonds Treatment
Plant and Engineering Division.
See Volume II of the Stormwater Manual for additional guidance on the selection and design of
construction -phase best management practices designed to prevent erosion and sedimentation.
