Surface Water Comprehensive Plan

The City of Lynnwood has completed its’ Surface Water Management Comprehensive Plan. This plan was assembled with grant assistance from the Washington Department of Ecology, and funds from the City’s Surface Water Utility. Information contained in this document was primarily assembled by the City’s consultant (Herrera Environmental Consultants) and City staff. This Stormwater Management Comprehensive Plan (plan) guides the City of Lynnwood’s (City) stormwater management program.

Surface Water Comprehensive Plan

The purpose of this plan is to meet regulatory requirements and address drainage and water quality problems in a way that aligns with the vision for the City’s future, as described in the City’s 2020 Comprehensive Plan. The recommendations in this plan support the goals, objectives, and policies expressed in the 2020 Comprehensive Plan, especially those contained in the Capital Facilities and Utilities Element, Environmental Resources Element, and portions of the Energy and Sustainability Element.

This plan is a substantial update to the last stormwater management comprehensive plan, prepared by the City in 1998. The 1998 plan focused on identifying and implementing capital improvements projects for flood control and water quality improvements, in addition to maintenance of the stormwater system. Since 1998, the City has made progress by expanding stormwater program coverage and constructing several capital improvement projects. Since many of the recommendations in the 1998 plan have not been fully implemented, this 2009 update builds upon previous recommendations and takes a broader look at the components of the City’s stormwater program in light of two recent regulatory developments.

Recently, the City has been affected by increasing state and federal stormwater quality regulations. These include the federal Endangered Species Act, the Swamp Creek Total Maximum Daily Load (TMDL) allocation for fecal coliform bacteria imposed by the Washington State Department of Ecology, and the National Pollutant Discharge Elimination System (NPDES) Phase II municipal stormwater permit issued to the City by the Department of Ecology. These regulations require the City to “ramp up” its stormwater management program to achieve compliance. This plan focuses on regulatory compliance, especially compliance with the NPDES Phase II permit, while also addressing flood control and other stormwater issues unique to Lynnwood and its residents.
