***Lessons Learned:***
**Hurricane Katrina Supplemental:**
* **process takes 1-2 years for 30 + libraries; *
* **benefits of taking existing Hydraulic Models where LIDAR and Cross Section exists ~90% Cost Savings;*
* **local support from RFCs, WFOs, and Partners.*
**Lower Colorado River Authority:**
* **Local H&H expertise; *
* **HEC-RAS Unsteady Analysis*
* **Quality Control;*
* **File Management;*
* **Learning Curve,*

***Partnerships:***
**Hurricane Katrina Supplemental:**
* **90% Cost Savings when partnered with NFIP community*
*   **- Detailed FEMA Flood Insurance Studies*
*   **- Existing Lidar and Hydraulic Models *
* **Local Hydrologic Knowledge of WFO’, RFCs, and Community **	**Stakeholders*
* **Seed Monies to demonstrate capabilities*
**Lower Colorado River Authority:**
*  **Strong working relationship *
*  **Current FIS hydraulic models*
*  **Sufficient topographic data and resolution*
*  **GIS capability is a big plus*
*  **$$$$$*

***RFC and WFO Roles:***
**Hurricane Katrina Supplemental:**
*  **Assist in site selection  *
*  **Solicit input/feedback from local partners/shareholders*
*  **Review  libraries for completeness, accuracy*
**Lower Colorado River Authority:**
*  **Act as liason between partner contractor, and headquarters *
*  **Identify roadblocks, oversights, problems*
*  **Keep the ball rolling*
