• Assigned weighting factors for functions and

measures

•Determined output data categories and

distribution

• Summarized results by analysis area/function

Considerations for Category Break

Determination

• Based on relative function scores

•Need enough categories to be meaningful and

useful in prioritizationuseful in prioritization

•Need outliers (extreme high and low values) to be

within similar groups

•Needs to be statistically-based

Page 29: City of Bellingham Habitat Restoration Master Plan - COB … · City of Bellingham Habitat Restoration Master Plan TAG Meeting February 26, 2013 ... Conceptual Model Memo Contents

Category Break Options Explored

• Based on various standard deviations from the

mean

• Based on quartiles (four equal categories)• Based on quartiles (four equal categories)

• Based on quintiles (five equal categories)

Nearshore/ Estuarine Habitat Group

• Analysis used methodology in WRIA 1 nearshore

assessment (CGS/Anchor 2013)

• Same methods as WRIA 1 analysis, but scaled to

project area project area

•Methodology rated stressors, analogous to

function ratings for other habitat groups

• EVC (Ecological Value Criteria) scores scaled to

project area.

• Existing conditions and results presented in

memorandum
