RE: DEP Agreement CN331 - Humiston & Moore Engineers Honeymoon Island State Park Change Order #3 Interim Beach Nourishment Task Assignment Number – 21

Dear Mr. McCullum, Jr.

In reference to direction from DEP JCP staff relating to physical monitoring requirements for the 2024/5 interim beach restoration project under construction at this time, we are providing this Change Order #3 to include the required post construction monitoring beginning one year post construction which will be August 2025 to remain consistent with annual monitoring surveys for this project and to provide a post hurricanes Debby, Helene, and Milton impact assessment for filing for FEMA funding assistance.

The scope for the post construction monitoring and FEMA storm impact assessment is provided in the following breakdown of tasks and costs. These are the same rates and relative costs approved under the main contract for the 2021 project (Task 17).

As noted above, this Change Order includes evaluation of impacts from Hurricanes Debby, Helene, and Milton in 2024 utilizing pre-storm monitoring data and post storm pre-construction data. The evaluation will be conducted to determine eligibility for Category G FEMA Funding Assistance based on sand losses from an engineered beach.

Sincerely, HUMISTON & MOORE ENGINEERS

Brett D. Moore, P.E., BC.DE.
