2012 Inventory Analysis
Data that meet or partially meet 3DEP specifications are available or in progress for 26.4% of the nation (includes AK, HI, PR & VI)
Bar chart depicts the amount of new data coverage that meets or partially meets 3DEP specifications by year since 2005

Of the data collected in 2012, 7% was repeat coverage; this equates to 0.4% of the nation’s area
Repeat coverage may include replacement of lower quality or older data, pre- and post-disaster coverage, collection for change detection, etc.

3DEP Acquisition Planning
Revise the acquisition approach with input from the 3DEP Executive Forum and NDEP
Establish a Broad Agency Announcement or other contract mechanism to streamline partnership development
Work with state and local partners to facilitate move to new planning strategy
Trial run of some steps (compiling agency requirements and plans against criteria) in FY14
Initiate 3 year planning in FY14
Implement new approach for FY15 (beginning in April, 2014)

3DEP Acquisition Planning
Areas with the highest net benefits as identified through the NEEA requirements study
Areas included in a federal, state or regional partner acquisition plan
Areas of no existing coverage
Areas with existing coverage that do not meet Quality Level 3 specification
Areas with coverage greater than 8-years old
Areas with significant topographic change
Areas subject to serious and significant hazards (earthquakes, landslides, volcanic activity, coastal flooding, sea level rise)
Striving toward economies of scale: fewer but larger collections
23
Prioritization Criteria
+Next Steps for California
Identify lead state agency and interagency working group
Continue to build inventory, repository, infrastructure
Refine state-agency requirements, add program costs and determine real $$ benefits to program
Roll that up to reflect needs and benefits across state agencies
Consider adding business needs from county/regional requirements (potential huge source of funding!)
Identify and align state sources of funding
Prioritize acquisition in a cost-effective fashion
All of this = An Elevation Plan for California
