The Mid-Reach Study
Objectives
Purpose
•Reduce storm damages to shorefront structures
•Maintain environmental integrity of beach and nearshore area
•Maintain recreational beach
• Hurricane and Storm Damage Reduction
Mid-Reach

Incremental Analysis
6 sub-Reaches
were identified
based on the acreage of
hardbottom
present
Acres of
Hardbottom

ALTERNATIVES CONSIDERED
• No Action (future without)
• Beach Fill (10, 20, 30-foot beach widths)
• Conventional Fill (20 to 160-foot beach widths)
• Dune and Vegetation
• Other Structural and Non-Structural Alternatives
were formulated but were screened out prior to the development of the final array

Formulation Strategy
• Initial Alternatives Screening
•6 reaches x 12 measures = 72
measures and over 4 million
alternatives
•Need a strategy!

Mitigation • Avoided and minimized impacts to
the nearshore rock habitat to maximum extent practicable
• Developed mitigation reef design for unavoidable impacts in Reaches 1 – 5 (approximately10% of total rock)
Mitigation Materials Testing
Consists of articulated concrete mats
embedded with coquina placed in a
water depth of 14 to 16 feet
