The Strategy’s recommendations, based primarily on the needs of salmon, provide an integrated approach to City activities to assure compliance not only with the Endangered Species Act but also with other federal and state environmental laws, including the Clean Water Act, the Growth Management Act and the Shoreline Management Act. The recommendations are based on data best available science, including data collected specifically for this purpose, and have been developed in coordination with staff from the National Marine Fisheries Service. Thus, they can be used to guide the City’s future activities and protect fish and wildlife habitat within its Urban Growth Area. City of Snohomish officials, at their discretion, can use the Strategy to update critical area regulations and the city’s shoreline management plan, establish a stormwater management program for its NPDES Phase II municipal permit, and develop best management practices for maintenance of public works, parks and riverfront property. The Strategy also identifies and prioritizes habitat restoration projects, which could be implemented through grants and other partnerships, mitigation requirements for public and private projects, and a variety of City programs meant to further conservation goals. One of the original goals of the ESA Strategy in 2001-02 was to provide the City the potential basis for an exemption from “take” prohibitions for Puget Sound chinook salmon, which was listed as a threatened “Evolutionarily Significant Unit” under the ESA in March 1999 (64 FR 14308). Municipalities such as Snohomish face the risk of federal agency enforcement and citizen lawsuits when listed species are adversely affected by their actions or inactions. To reduce its liability, the City intended to seek approval for certain activities subsumed under one or more “limits” or exceptions to take prohibitions specified under Section 4(d) of the ESA. A 4(d) rule limit provides qualifying governments or individuals with a safe harbor from federal enforcement under the ESA, and greatly reduces the threat of litigation. As originally conceived, the Snohomish ESA Strategy was to be patterned after a similar effort then underway at the regional level. The “Tri-County” Salmon Conservation Coalition, which represented public and private interests across Snohomish, King and Pierce Counties, was seeking 4(d) rule exemptions for several county programs, including public water systems, road construction and maintenance, and stormwater management. By applying lessons learned in the Tri-County experience to the City of Snohomish’s specific needs, the ESA Strategy sought to provide protection for chinook salmon sufficient for NMFS approval, at a reduced cost to the City and its citizens. vi City of Snohomish ESA Response Strategy ______________________________________________________________________________________ The Tri-County coalition ultimately decided not to pursue 4(d) rule exemptions and, for now, it appears prudent for the City to do the same. The legal risks of liability for take appear relatively small due to the difficulty of proving that a program or suite of actions causes the take of individual fish.

  • Narrative and Graphic Source Material
    Source descriptions for features in a geodatabase of Puget Sound’s pre-settlement river valley, estuary and nearshore habitats (September 14, 2008 version) Introduction This is a supplement to a Geographic Information System (GIS) geodatabase of the Puget Sound area’s riverine and nearshore environments as reconstructed for the pre- settlement (mid-19th century) era. It consists of descriptions of mapped features. The descriptions include source materials that were used, and discussion on how they were used. Features are primarily wetlands, channels, and landforms. Features are indexed by an identifying code that is linked to the geodatabase. The code consists of three letters that identify the river or oceanographic basin, followed by the township and range (all townships are North, and ranges are identified as East or West, by “E” or “W”) and a number given to features sequentially within each township. Some nearshore features are identified by a separate coding system consisting of a WRIA (Washington Water Resource Inventory Area) number and a unique number within the WRIA. Numerous excerpts from Public Land Survey (PLS) field notes are included; generally the notes’ idiosyncratic usage, grammar, and punctuation are preserved. At present this document contains source descriptions for aquatic habitats. With time descriptions will be added of additional features, or more information will be added for features already in the narrative (e.g., on the seasonal inundation characteristics of wetlands). Source descriptions will also be added for different types of features not included at this time (e.g., forest composition). How to cite this document: Collins, B. D. 2008. Source descriptions for features in a geodatabase of Puget Sound’s pre-settlement river valley, estuary and nearshore habitats (September 14, 2008 version).

In 2015, the Skykomish-Snohomish Rivers Coalition (the Coalition) formed to address the growing recreational pressure on these rivers. A working group composed of “over 25 entities representing federal, tribal, state, and local governments and agencies, businesses, civic groups, non-profit organizations and residents” met regularly to develop a “shared vision and plan for coordinated, well-managed, sustainable recreation on the river system.” One result of the discussions that have been ongoing since 2015 is the Skykomish-Snohomish Rivers Recreation Concept Plan, with a working draft released in August of 2018. The concept plan included a series of visions and goals as well as key considerations for coordinated recreation management. The plan also provided general recommendations and proposed public river access sites accompanied by a detailed inventory of current landowner management. Among the major concerns expressed in the plan were safety on the rivers and protection of fish and habitat as recreational use increased. As part of ongoing efforts to address these issues, Snohomish County Parks, Recreation, and Tourism funded a project in 2018-2019 to develop and recommend a Wayfinding and Interpretive Signage Program for up to 11 access sites designated along the Skykomish-Snohomish River system.
