DRERIP will implement adaptive management by incorporating scientific evaluation of
restoration actions in light of the current state of knowledge and restoration projects
implemented to date. The DRERIP science input process is divided into four phases; (1) process
design; (2) the development of species life history models and ecosystem element conceptual
models; (3) the development and evaluation of proposed ERP actions; and (4) an
analysis of the feasibility and prioritization of the actions.
Science Input Process provides a detailed discussion of the process.
Please note: Science Input Process Map
documents are draft. Discussions regarding the science input
process are ongoing and process map documents may be revised at the discretion of the AMPT.

Phase 1: Process Design
Phase 1 involved establishing the overall process, including this Process Map, and defining the product
development groups, including membership and leaders. This phase involved activities primarily by the Working Group
with input from the ERP Science Board and Adaptive Management
Staff support, including GIS support, web-based support, and electronic library
support for the DRERIP was marshaled during this phase. The GIS and other support tools will be engaged throughout
the plan development process and used specifically to facilitate communication and science input. Species Experts
have been identified and Action Team Co-leaders
were also recruited in Phase 1.
The phase ended with approval of the
Process Map by the ERP Implementing Agency Managers (as denoted by a decision diamond on the Process Map) and briefings to public/stakeholder
groups. Specific tasks and products produced in this phase included:
- A Process Map detailing the teams, subsequent phases and interactions;
- Membership and commitments for each of the product development groups;
- Development of draft species life cycle models;
- Instructions for the Species Experts, including a template for the development of species life history models;
- Initiation of the scientific evaluation process development;
- Definition of a Peer Review Strategy; and
- GIS, web, and electronic library support structure.
Phase 2: Conceptual Models
Phase 2 represents the first technical step in the process and is aimed at describing the
scientific state of knowledge about key Delta species and key ecosystem elements through development of conceptual
models. This will involve the engagement of approximately 30 Species Experts over a four to five month period to
develop species life history models as well as engagement of the Action Team in the development of ecosystem element
As the species and ecosystem element models are completed they will be used to
develop and evaluate ERPP
actions and develop Chapter 5: Delta ERP Actions in an Adaptive Management Context. The completed models will also
be posted on this website as a resource for ecosystem restoration project proponents.

The process for evaluating ERP actions (Phase 3) will also be finalized in Phase 2, including a
review by the CBDA Independent Science Board (ISB) as described in the Peer Review Strategy
(Attachment 3 (31k) Adobe PDF ).
Phase 3: Evaluation of ERP Actions
Phase 3 will involve an effort to develop new and evaluate all previously identified Delta actions
(including those from the ERPP Volumes I and II, Strategic Plan, Water Quality Program Plan, Draft Stage 1
Implementation Plan and Record of Decision (ROD; ERP-MSCS Milestones), Delta
Smelt Action Plan) in terms of the issues identified in the
species life history and ecosystem element models. This evaluation will be conducted largely by the Action Team
using the scientific evaluation process as reviewed by the CBDA ISB and will address why each of the actions and targets is relevant
for restoring the Delta.

Phase 4: Feasibility and Priority Setting
The final phase of the process will focus on identifying how actions evaluated in Phase 3
could be implemented, including the feasibility of various actions and establishment of priorities for implementation.
The feasibility assessment and priority setting will include consideration of physical, financial, social-political
issues, and relationship to the actions of other Bay-Delta program elements and will be based on the prioritization
process developed during Phase 3. The feasibility assessment will be conducted by the Action Team supplemented with
additional members as needed to incorporate adequate consideration of engineering and other feasibility factors. The
AMPT will then prioritize the actions that have been vetted from a scientific and feasibility standpoint in
coordination with the Working Group and ERPIAMs.
During Phase 4 the AMPT will revise their initial priority setting based on review by the ERPSB and ERPIAMS.
The draft DRERIP will be reviewed by the Technical Review Panel. The phase will end with approval for release of the
draft plan by the ERPIAMs, a public review period with briefings to the ERPSB, Agency Coordination Team and the
Ecosystem Restoration Subcommittee, and approval of a final plan by the ERPIAMs and the CBD Authority.
