Compare Dock Styles

Although totals shown in the indicators report only two types of docks (e.g., individual or shared), there are several differences within those categories worth noting. For instance, each individual or shared dock may vary in: structure size, number of boats slips allowed, general shape, and length. While this additional information will not change the total number of docks reported by type, it does change the relative impact each dock has on the water body.

Dock Styles by Scenario Dock Style Characteristics
Boat Slips Per Dock Maximum Size Maximum Float Size Maximum Length
Current Individual Dock 1 490 sq ft 100 sq ft 100 ft
Shared Dock        
Build-Out Individual Dock 1 490 sq ft 100 sq ft 100 ft
Shared Dock        
Scenario A Individual Dinghy Dock 1 140 sq ft 50 sq ft 30 ft or 2 ft water depth whichever is least
Shared Dinghy Dock up to 3
Scenario B Shared Dinghy Dock up to 3 140 sq ft 50 30 ft or 2 ft water depth whichever is least
Shared Dock up to 3 420 sq ft 200 100 ft or 3 ft water depth whichever is least
Shared H-Dock up to 6 848 sq ft 592 100 ft

Maximum Size

Maximum size was obtained by using the maximum length, width, and float sizes for this dock style as listed in the regulations or hypothetical regulations. These were combined using a formula to get the average size in square feet.

Maximum Length

All maximum length requirements are measured from the landward edge of the marsh, or if no marsh grasses exist measurements are taken from the mean high tide line.
