RE: DEP Agreement CN331 - Humiston & Moore Engineers Conceptual Alternatives Analysis for Coastal Resiliency Enhancements Gasparilla Island State Park Change Order #1 Interim Beach Nourishment Task Assignment Number 22

Dear Mr. Sandel, In reference to recent conversations regarding the use of ARPA funds toward an interim Beach Nourishment, we are preparing this Change Order to address the necessary tasks needed to develop the plans and technical specifications to support bidding and selection of a contractor in 2024. We intend to use existing data which we have collected as part of Task Assignment 22, in conjunction with existing monitoring data from previous restoration efforts on Gasparilla Island. In addition, we have included relative costs for support through the bidding phase. The scope for the construction phase and post construction certification and as-builts is provided and costs will be determined once the design is completed and accepted by your Department.

Sincerely, HUMISTON & MOORE ENGINEERS
