Selection Criteria For LWP Area
Contain anticipated quantity / types of mitigation projects
Consider willingness of local RPs (and other stakeholders) to work with EEP
Consider scale and potential to evaluate water quality or habitat improvements
Local Watershed PlanningLocal Watershed Planning
Purpose
identify major causes/sources of impacts to water quality, habitat and hydrology and develop strategies for addressing these watershed stressors.
Goal
ensure that projects are selected and located to achieve maximum long-term improvement to local watershed functions.
Local Watershed Planning: Phase ILocal Watershed Planning: Phase I
Preliminary Watershed Characterization
Preliminary characterization of watershed conditions & functional needs based on best available data/GISProducts:
• Collection and evaluation of existing data
• Identification of critical data gaps
• Convene Local Advisory Team
• Develop Outreach Strategy
• Preliminary Findings & Recommendations report
