SCOPE OF WORK

702 South Ridgewood Avenue – Flood Mitigation Improvements Daytona Beach, Florida | Volusia County, Florida

1. Project Overview On September 28, 2022, the outpatient services facility located at 702 South Ridgewood Avenue, Daytona Beach, sustained significant flood damage as a result of Hurricane Ian. The structure is a brick-on-concrete-masonry-unit (CMU) building with a first-floor elevation of 5.14 feet above sea level (NAVD 88), as established by the recorded Elevation Certificate.

The objective of this project is to implement passive flood mitigation improvements that will protect the building to a flood elevation of 8.0 feet above sea level without requiring human intervention prior to a storm event. The design strategy achieves this protection level by adding three (3) feet of waterproofing and flood-resistant construction above the existing first-floor elevation, replacing existing openings with flood-rated assemblies, and elevating mechanical and electrical equipment above the 8.0-foot flood protection datum.

The improvements are consistent with the Transform 386 Ridgewood Flood Mitigation Application and have been developed through site assessment and pre-construction coordination. All work shall be performed in accordance with applicable provisions of the Florida Building Code (FBC), local Volusia County building requirements, and the floodplain management standards of the National Flood Insurance Program (NFIP).

2. Existing Conditions The Contractor shall be responsible for independently verifying existing site and building conditions prior to submission of a bid. The following conditions are provided for informational purposes based on pre-design assessment:

1. First-Floor Elevation: 5.14 feet above sea level (NAVD 88) per the recorded Elevation Certificate.

1. Existing Openings: Multiple storefront doors and windows currently extend to or near finished grade, providing no flood resistance below the 8.0-foot flood protection datum.

1. Existing Doors: A combination of hollow metal (HM) and glass storefront doors are present on the north and south elevations. See Section 4.6 for a complete listing of openings.

1. Existing Windows: Windows on the south elevation currently extend to near grade level and are not flood-rated.
