2. INTRODUCTION

2.1.1 PROJECT DESCRIPTION

The 7th Avenue Pier is located in the City of St. Pete Beach, Pinellas County, Florida on the Pass-a-Grille

Channel, at the east end of 7th Avenue. Originally built in 1980, the 7th Ave. Pier is a T-shaped pier, last repaired in 2021, that extends 76 FT into Pass-a-Grille Channel providing a fishing pier and recreational amenity of approximately 2,844 SF. The pier is constructed of pressure treated (PT) wood piles, PT wood beams, cross-bracing, joists, composite decking, trash receptacles and benches.

The pier was damaged due to the storms between 09/23/2024 and 10/07/2024. On September 26, 2024, Hurricane Helene hit the Gulf Coast with a Category 4 hurricane and on October 5, 2024, the Gulf Coast was hit again by Hurricane Milton. Both storms caused widespread damage to the area and to the Pier.

2.1.2 LOCATION

The structure is located at 700 Pass-a-Grille Way, St. Pete Beach, Florida, 33706 (27° 41’ 14” N; 82° 44’

10.7” W.). Furthermore, it is in Section 19, (No Township or Range), in Pinellas County, on the Pass-a-

Grille Channel. The structure is accessed directly at the east end of 7th Avenue, just east of Pass-a-Grille

Way.

2.1.3 INSPECTION PROCEDURES

This inspection consisted of a submerged structure review of the integrity of the piles and their associated jackets and bents from below the decking to the dredge line (mudline) of the piles. Divers from Dive Tech

International, Inc. performed a submerged visual inspection with video and still images, have been provided with this report.

Divers visually inspected and videoed 60 piles, associated bents and cross members.

2.1.4 INSPECTION CHECKLIST

Divers are to identify and document observable conditions such as marine growth, scour, corrosion, spalling, cracking, section loss, misalignment, or impact damage. The Underwater Inspection of the 7th

Avenue Pier was performed by Dive-Tech International, Inc. (DTI) with a team of three divers. Overall, the sub-structure was in fair condition with multiple deficiencies and damages noted. Appendix A contains the

Transcribed Underwater Field Report and Deficiencies Notes produced by Northstar from the DTI Field

Report. Appendix B contains the original DTI Field Report and pictures as well as additional pictures of the damaged super-structure and deck.

Definitions:

TLW: Typical Loose Wrap/Jacket. A typical condition of a pile wrap where the wrap is disconnected from the pile and moves.

TMGP: Typical Marine Growth Penetration. A typical condition where marine growth has penetrated the pile wrap/jacket.

EMBA: Evidence of Marine Bore Attack.

JNTB: Jacket Not Touching Bottom. A typical condition where the jacket/wrap does not penetrate the dredge line/mudline at the pile.

2.1.5 GENERAL CONDITION DESCRIPTION

Overall, the sub-structure is in fair condition. Due to every pile having a wrap of some type on them, a visual inspection of the pile itself was not possible in the areas of the wrap/jacket. There are several types of wraps/jackets installed on the piles:

1. PVC Wrap filled with concrete.

2. PVC/HDPE wrap connected directly to the pile.

3. Fiberglass wrap connected directly to the pile.

No piles exhibited any evidence of breakage or loose foundation.

More specific information regarding each deficiencies noted, including location maps, and photographs of the deficiency are provided in the report below.
