Appendix C. Goals and Targets of the National Earthquake Loss Reduction
Program (NEP)
The National Earthquake Strategy Working Group recognized that NEHRP lacked
an effective means of coordinating non-NEHRP agencies' earthquake activities,
as well as efforts of non-governmental and state and local governmental
sectors dealing with earthquakes. A major difficulty in evaluating the success
of NEHRP and identifying future priorities has been the lack of specific
goals, targets, and products against which performance can be measured or
expectations revised. The new strategy establishes specific integrated and
coordinated research targets and associated products with timelines for
completion. Though these targets will undoubtedly be revised, modified,
and supplemented as more is learned about earthquake loss reduction, they
provide a framework for measuring progress.
The following sections set forth the primary goals that define the strategy.
Each goal has several targets which in some cases could be described as
projects, but generally are more broadly based. While the targets are prioritized
in order of decreasing importance, the goals are not. For most targets one
or more products have been identified. The aim of the strategy is to maintain
a focus on these products as the separate supporting projects are developed,
conducted, reviewed, and completed so that information and technology transfer
meets public expectations on national earthquake loss reduction. Consistent
with their mission, the Federal agencies planning allocation of limited
earthquake-designated resources will take into account the specific targets
and products identified as high priority issues by the user community in
both the public and private sectors. The dates suggested for meeting targets
or completing products are estimated guidelines, not commitments.
Funds for the attainment of these goals are presumed to be limited to those
currently in the budgets of agency programs involved in earthquake research
or loss mitigation technology development.
Goal 1: Provide leadership and coordination of federal earthquake research
Targets:
1. Work with the National Science and Technology Council to establish a
leadership mechanism to assure implementation of the Strategy. The mechanism
shall report every two years to the President and to the Congress on its
findings, progress, and recommendations relating to earthquake risk reduction.
Leadership mechanisms are needed for both national oversight and day-to-day
coordination functions.
2. Integrate federal earthquake-related program planning into the new mechanism
over a five year period beginning in Fiscal Year 1996. This shall include
a detailed analysis during FY 1996 of agency expenditures and planned expenditures
with the objective of identifying any redundancies and redirecting expenditures
toward high priority targets.
3. Develop a balanced national prioritized research and mitigation agenda,
confirmed or adjusted on a regular basis, incorporating a broad-based assessment
of user needs that includes the needs of agencies to support special or
unique missions.
4. Facilitate cooperation and leverage across all agencies and groups with
programmatic interests in earthquake loss reduction, including, but not
limited to federal, state, local, private, voluntary, and public utility
agencies and groups.
5. Develop an overall nationwide strategic plan to integrate and coordinate
existing but currently separate research and mitigation programs into a
unified, needs-driven, goal-oriented program consistent with the National
Earthquake Strategy goals.
6. Advocate policies and practices nationwide and recommend legislation
as appropriate.
7. Conduct a biennial performance assessment and report of coordination
and integration activities under the Program. This report shall include
accomplishments towards achieving the goals and recommendations for improving
the Strategy. As the Program matures the assessment and report can be conducted
at less frequent intervals.

in research on earthquake loss reduction and in technology transfer for
