a Project management, PIMS system programmers, and testing/documentation staff would be budgeted at the GS13 salary range, about $125,000/year including benefits. The initial GS13 staff would be 4.5 in number (1 Project Lead at 0.5 FTE, 3 FTE system/software programmers, and 1 FTE testing/documentation staff). Administrative assistance and systems management would be budgeted at about $70,000/year including benefits, and would require 1 FTE (4.5 * $125,000/year + 1 * $70,000/year = 562,500 + 70,000 = 632,500).
b Each pilot project is estimated to have a development phase with 1 FTE at $90,000/year and an implementation phase with 1 to 2 FTEs at a cost of $140,000 to $420,000 per year, for a total cost of $230,000 to $510,000 per pilot project. For budgeting, an average of $370,000 per pilot project is assumed.
c Operation costs include project management, systems management, administrative assistance, user support, and maintenance programmers. It also includes data expansion and travel. All total, operation costs are estimated at $600,000 per year during Phase II, and $460,000 per year after Phase II.
TABLE E.3 Task Breakdown and Scheduling for Task 11: Observatory Network on Community Resilience and Vulnerability
Year | Annual Cost | Unit Cost | Cost Explanation |
Year 1 | $1.8 million | (a) new location nodes: $400k/yr (b) existing centers: $200k/yr | Annual cost assumes 6 nodes established in Phase I (3 at new locations, 3 at existing research centers). New nodes: personnel and infrastructure cost to establish node functions; initiate data collection. Existing centers: Less costly, as would build on existing personnel/ infrastructure. |
Year 2 | $2.2 million | (a) and (b): Same as Year 1 (c) network coordinating grant: $400k/yr | 6 nodes continue. Network coordinating funds (NCF) to facilitate and institutionalize coordination functions (e.g., measurement protocols, data archiving, network website, workshops, etc.). |
Year 3 | $3.8 million | (a), (b), (c): Same as above | 6 nodes and NCF continue. Add 4 new nodes, potentially including “living laboratory” nodes. |
Year 4 | $3.8 million | (a), (b), (c): Same as above | 10 nodes and NCF continue. |
Year 5 | $2.85 million | (a): $300k/yr (b): $150k/yr (c): $300k/yr | 10 nodes and NCF continue. Cost reductions as infrastructure now set up and most urgent network actions completed (e.g., common measurement protocols, data archiving, etc.). |
5-year TOTAL | $14.45 million | Sum of Years 1~5 costs. | |
Years 6~20 | $2.85 million/yr | Maintain Year 5 funding levels; some nodes may end and be replaced by others through competition. | |

a Task 18 Assumptions:
• Community component (ramping up and down)—The proposal is to identify early adoption communities to conduct pilot and demonstration programs in about 280 communities. The project would begin by selecting 10 pilot communities in years 3 and 4 to test and develop the program and materials. In years 5-16 the project would add 20 demonstration communities. Pilot and demonstration communities would receive an average of $750,000 per year for 4 years after which they would be expected to have the information, understanding, tools, organizations, motivation, and support needed to sustain resilience-improving efforts into the future.
• Data collection (data profiling) would occur during the first 2 years in coordination with development of the strategy, and then each year as new communities require individual hazard assessments, etc.
• Program management and support staff costs would be budgeted at the GS13 salary range, about $125,000/year including benefits. The initial staff would be 4 in number, 3 additional staff persons would be added in year 4, and 3 additional staff persons in year 10 for a total of 11. (4 × 125 = 500,000; 7 x .125 = .875; 11 x .125 = 1.375)
• Existing centers at Delaware (DRC), University of South Carolina, Texas A&M, UCLA, USC CREATES Center have the capability to do community assessments and evaluation of the program and individual communities.
• National outreach provides funds for providing information, engaging specialists, evaluating events that occur, etc.
• Consultation at the state level will be important in the selection and support of the communities.
• Leverage with the other components—National Seismic Hazard Maps, HAZUS, community-specific hazard maps, earthquake provisions in codes, training materials for professionals, learning from earthquakes presentations at annual workshops, NSF could sponsor research on the process.
• Must describe outcomes of more resilient communities in more meaningful terms such as codes adopted and enforced, community understanding, land-use plans that consider earthquake hazard, that measures taken before earthquakes will have a multihazard application
• Community strategy could “require” a comprehensive school earthquake safety element (awareness, curriculum, preparedness, building analysis and mitigation).
