Stormwater Management Action Plan
The City of Lakewood owns and operates a stormwater conveyance system that discharges collected stormwater into bodies of surface water under the terms of the National Pollutant Discharge Elimination System (NPDES) Western Washington Phase II Municipal Stormwater Permit. The current iteration of the NPDES permit, issued August 19, 2019, stipulates in special condition S5.C.1.d that each permittee must complete a Stormwater Management Action Plan (SMAP). The SMAP is a planning process that has resulted in the identification of specific actions to address water quality concerns in high-priority watershed within the permittee’s jurisdiction. The SMAP is currently made up of three documents as follows:
- Receiving Water Conditions Assessment
- Receiving Water Prioritization
- Stormwater Management Action Plan
- Stormwater Management Program
Receiving Water Conditions Assessment
This report comprises a complete Receiving Water Conditions Assessment (RWCA) for the City of Lakewood developed using the following steps:
- Delineate Basins and Identify Receiving Waters
- Assess Receiving Water Conditions
- Assess Stormwater Management Influence
- Assess Relative Conditions and Contributions

- Explanation of the prioritization criteria that are used to rank the receiving waters
- Discussion and scoring of the candidate receiving waters
- Conclusions and recommendations
