  • Information to support

    watershed-based land use

    decisions

    Puget Sound Watershed Characterization Project

    1

  • Concerns that have been expressed regarding PS Characterization

    From meetings with EPA, letters, Habitat Advisory Committee comments we have heard:

    Concern that PS Watershed Characterization is

    inconsistent with and should not supplant Salmon Recovery Plans

    Tribes need to be engaged in PS Watershed Characterization - bring in local data to improve results

    Concerns with Habitat Assessments done by WDFW

  • Focus of this meeting

    Discuss Tribal concerns regarding the Puget Sound Watershed Characterization

    How PS Watershed Characterization might support Salmon Recovery efforts.

    Discuss the roles and potential applications of watershed characterization and salmon recovery plans in land use planning and policy.

    Initiate conversations of how WCTAT should work with tribal staff to incorporate finer scale data and assessments into local plans being developed in conjunction with the WCTAT.

    Overview of PS Characterization and initial applications of assessments to local planning efforts

    Who is using currently PS Characterization. Who will?

    Integrating assessments and other data to provide guidance in local planning: current application Kitsap County Nisqually integration work initial analysis

    Discussion on how to bring finer-scale tribal and local data into assessment framework efficient and effective.

  • PUGET SOUND WATERSHED CHARACTERIZATION

    Brief Overview

  • The Puget Sound Watershed Characterization Project

    A multi-agency effort to provide land use planners with a watershed context for decision making Comprehensive Plan updates Shoreline Master Program Sub-area plans

    A resource for conservation planners and restoration practitioners across Puget Sound. Inform mitigation or restoration design at coarse scale TDR programs Conservation easements

  • Identify Important Areas for Supporting Processes

    Infiltration & Recharge

    Storage

    Groundwater discharge

    Delivery of water

    Longshore drift

    Objectives of Characterization

  • Purpose of the Characterization

    Where on the landscape should planning and management efforts be focused first

    What general types of activities and actions are most appropriate at that place

    Why are those places relatively more or less important than other places

    Does not model rates or quantities for: instream flows Mid & Finer Scale Modeling done by sediment Salmon Recovery Plans wood

  • Helps protect/restore processes that maintain healthy stream systems

    Ecosystem Services:

    ..such as water and sediment movement at the watershed scale

    ..such as a stream channel or estuary delta

    Mid Scale

    ..such as habitat for birds

    Fine Scale

    Broad Scale

    8

    Broad scale water flow assessment

    Mid & fine scale - In stream flows modeled by Salmon recovery plan

    Water Flow model establishes overall land-use recommendations

  • Complements Salmon Recovery Efforts Broad scale water flow assessment

    Mid & fine scale - Salmon recovery plan, using finer scale data, identifies specific location & design of stream restoration

    Water Flow assessment deals with upland land use that controls the delivery & movement of water to streams

    Yellow colors tell planners that land-use practices should support restoration of watershed processes Green colors indicate that land-use practices should continue protecting watershed processes

  • Complements Salmon Recovery Efforts Broad scale water flow assessment

    Mid & fine scale - Salmon recovery plan, using finer scale data, identifies specific location & design of stream restoration

    Water Flow assessment deals with upland land use that controls the delivery & movement of water to streams

    Yellow colors tell planners that land use practices need to be changed. Green colors indicate that current practices are OK

  • Water Quality Models

    Source Sink Models for: Sediment Phosphorus Metals Nitrogen Pathogens

    Export Potential how readily a given AU can deliver sediment (or N, Metals, etc.) based on landscape features.

    Degradation - N-SPECT model that characterizes the degree of existing degradation to processes (sediment, N, Metals, etc.) based on land-use type.

    Can combine the two models to provide guidance on which areas to prioritize
