EVALUATION
QUANTIFY AND JUDGE CONTRIBUTIONS OF PLANS
ASSESSMENT: Measure/ quantify differences
APPRAISAL: Judge/ weight differences
FIND VALUE OR WORTH OF PLANS
IDENTIFY PLANS to carry through to COMPARISON
RE-FORMULATE & RE-EVALUATE as necessary

EVALUATION AND COMPARISON
EVALUATION - LOOK AT PLAN ON ITS OWN MERITS (With project vs. Without project conditions)
COMPARISON - CONTRAST THE MERITS AMONG PLANS (Plan vs. Plan)

BUILDING STRONG®
INSTITUTIONAL SIGNIFICANCE
The importance of an impact (effect) is recognized in laws, programs and policies:
Federal: ► Principles and Guidelines – NED & EQ impacts► ER 1105-2-100 – primary, secondary, incidental benefits► Endangered Species Act; Clean Water Act► Annual Budget EC 11-2-xxx (ex: for 2010 -193): provides ranking criteria
(scarcity, connectivity, special status species, plan recognition, self-sustaining, cost/acre)
State/Regional: ► Laws creating non-Federal entities (Port Authorities, Flood Control
Districts, etc.)► Ex: Chesapeake Bay Agreement
Local/Tribal: ► Budgets allocated for funds to restore, preserve, etc.

CRITERIA TO DEFINE STANDARDS:► Planning objectives & constraints► Federal objective► Environmental compliance, consultation and
coordination requirements► P&G criteria► Requirements specific to authorization
• e.g., “Savings Clause” in WRDA 2000 ► Key stakeholders’ concerns

PLANNING OBJECTIVES
Objective - Reduce current risk of damage due to flooding.► Does the plan achieve the objective?► To what extent is the objective met?
Constraint – Maintain at least existing level of flood protection► Does the plan avoid/meet the constraint?

► COMPLETENESS► EFFECTIVENESS► EFFICIENCY► ACCEPTABILITY

A Note Regarding Iteration…
Will re-formulation & re-evaluation occur? ► Most likely!
Why?► PDT learns from evaluations► More information becomes available► Our understanding improves
Ex:► Initial science indicates correcting salinity levels will restore
estuarine biota (PROBLEMS & OPPORTUNITIES)► So… alternatives are FORMULATED to deliver appropriate
freshwater flows to estuary► Subsequent modeling (EVALUATION) indicates that correcting
salinity & flows are insufficient to restore estuarine biota► So… alternatives are RE-FORMULATED to include measures to
address additional WQ nutrient requirements► Subsequent modeling (RE-EVALUATION) quantifies improvements
to biota resulting from re-formulated alternatives► And so on…

Review
Evaluation comprises objective Assessment & subjective Appraisal
Effects measured as the difference between with & without project conditions
Many procedures developed to quantify NED, NER, EQ, & physical effects of alternative plans
4 accounts provide flexible framework for identifying & summarizing plan effects
Plans qualified for further consideration Re-evaluation (& re-formulation) often part of iterative
planning process
