The second decisional milestone during the feasibility study is the Tentatively Selected Plan Milestone, which occurs after the District has selected a Tentatively Selected Plan and when it is preparing to release the draft report and draft NEPA documentation for concurrent public, technical, legal and policy review and independent external peer review (if applicable). At the TSP Milestone, the decisionmaker (the Major Subordinate Command (MSC) Planning Chief for studies where approval has been delegated to MSCs or the Headquarters Chief of the Planning and Policy Division if approval resides at HQ) determines if the analyses and findings to date are sufficient to approve release of a draft integrated feasibility study report for review.
Between the Alternatives Milestone and Tentatively Selected Plan Milestone, the Project Delivery Team (PDT) is using a reasonable level of detail to collect data and model alternatives to analyze and evaluate effectiveness with the intent of identifying a Tentatively Selected Plan (TSP). The PDT has completed the evaluation and comparison of a focused array of distinctly different strategies for achieving the water resources objectives in the study area; identified a TSP and possibly a LPP to carry forward; and prepared a proposed way forward to develop sufficient cost and design information for the final feasibility-level analysis and feasibility report.
The Tentatively Selected Plan (TSP) Milestone meeting ensures the Vertical Team’s concurrence on the TSP that will be released as part of the draft integrated feasibility study report for public and agency review. Ongoing Quality Control and Quality Assurance, complemented by formal and informal Vertical Team interactions, are expected to facilitate reviews that will occur when the draft report is released no later than 60 days after a successful milestone.
At the milestone meeting, the PDT will produce an updated decision log and draft Memorandum for Record (MFR) of the meeting documenting decisions and agreements.
The District will use the TSP milestone discussion, along with any action items and decisions, to inform the completion of the draft feasibility report. Draft report documentation should follow ER 1105-2-100, Appendix G, general evaluation guidelines (Exhibit G-1) and PB 2018-01(S), and be compliant with NEPA and other applicable laws, policies and regulations (Exhibit G-8). The draft report package will undergo DQC prior to concurrent public, ATR, IEPR (if applicable) and policy and legal compliance review.
The PDT will be required to provide a level of detail of documentation on the TSP that is commensurate with other alternatives analyzed. It is expected that limited additional TSP detail will be included for this public draft report. Details related to the recommended plan will be developed and evaluated as part of the next phase of the study.
