Northwest Florida Water Management District

Monday, August 22, 2011

DiscoveryDiscovery process requires data mining, collection, and analysis for initiating risk discussions within the watershed and determination of Risk MAP projectsRequired for any potential Risk MAP projectWhen:

After an area/watershed has been prioritized and sequenced

Why: Increases visibility of flood risk information, education, involvementPromotes the idea of watershed conceptHelps inform whether a Risk MAP project will occur in

the watershedDiscovery is flexible and scalable to the watershed

Watershed Stakeholder Coordination

Coordinate With Communities And Other Watershed Stakeholders

Data Analysis

Data analysis allows focused discussions on the goals and objectives of Risk MAP.

Discovery Map

Appendix I guidelines covers all the details of what we should include on the Discovery Map.

The Discovery Map will be finalized after the meeting and will be provided to the communities.

Discovery ReportA draft Discovery Report will be created using the data and information collected during Discovery and will be updated to include any new information obtained at the Discovery Meeting.

A final Discovery Report will be provided to the communities after the Discovery Meeting.

Project Determination

Project needs are identified by the water shed stakeholders. Once it is determined a flood risk project is appropriate, the final Discovery Report will be updated to reflect that decision.

At the time the decision is made whether to move forward with a flood risk project in the watershed, the project team must update FEMA databases.

Post-Meeting Coordination

The post-Discovery meeting coordination and communication must occur prior to initiating a flood risk project.

Coordination will be flexible and may occur in a number of ways.

Scope Refinement

Coordination with watershed stakeholders to Refine scope including a decision about:

What regulatory and/or non-regulatory products may we provide? What mitigation planning technical assistance that may we offer? What communication and outreach assistance may we provide?

Finalize and deliver Discovery products (Discovery Map, Discovery Report)

Coordinate with communities with the objective to execute the project charter/MOU
