The purpose of the Aquatic Development Zone is to provide for navigation and other identified needs for public, commercial, and industrial water-dependent uses in the Columbia River Estuary. The objective of the Aquatic Development Zone is to ensure optimum utilization of appropriate aquatic areas by providing for intensive development. Such areas include deep water adjacent to or near the shoreline, navigation channels, subtidal areas for in-water disposal of dredged material, areas of minimal biological significance needed for uses requiring alteration of the estuary, areas that are not in Aquatic Conservation or Aquatic Natural Zones, and areas for which an exception to Statewide Planning Goal 16, Estuarine Resources, has been adopted.
The following uses and activities and their accessory uses and activities are permitted in the A-1 zone if the Community Development Director determines that the uses conform to the standards in Section 16.72.040, applicable Development Code standards, and other City laws:
A. 
Water-dependent commercial or industrial uses, including in-water log storage and industrial piers and wharves.
B. 
Navigational structures.
C. 
Water-dependent public recreational facilities, including boat ramps, docks, moorages and marinas for commercial and recreational marine craft.
D. 
Shoreline stabilization.
E. 
Flow lane disposal of dredged material.
F. 
Pipelines, cables, and utility crossings.
G. 
Stormwater and treated wastewater outfalls.
H. 
Temporary dike for emergency flood protection limited to 60 days subject to state and federal requirements.
I. 
New dike construction.
J. 
Maintenance and repair of existing structures or facilities.
K. 
Dredging and filling, pursuant to the applicable standards in Section 16.160.040 for any of the permitted uses.
L. 
The following water-related commercial and industrial uses:
1. 
Boat and/or marine equipment sales.
2. 
Fish or shellfish retail or wholesale outlet.
3. 
Charter fishing offices.
4. 
Sports fish cleaning, smoking, or canning establishment.
5. 
Retail trade facilities for the sale of products such as ice, bait, tackle, gasoline or other products incidental to or used in conjunction with a water-dependent use.
6. 
Restaurants which provide a view of the waterfront, and which are in conjunction with a water-dependent use such as a marina or seafood processing plant.
7. 
Cold storage and/or ice-processing facilities independent of seafood processing facilities.
M. 
Navigation aids.
N. 
Piling as necessary for any of the permitted uses listed above.
O. 
Bridge Crossings. Temporary encroachments in the floodway for the purposes of bridge construction and repair:
1. 
This use shall comply with Chapter 16.88 (Flood Hazard Overlay (FHO) District) prior to issuance of any permits.
2. 
The temporary permit shall state the number of days the structure or other development will be on the site. If a longer period is required, a new permit shall be issued.
3. 
A flood warning system for the project should be in place to allow equipment to be evacuated from the site and placed outside the floodplain.
4. 
Placement of equipment in the floodway should be restricted to only equipment which is absolutely necessary for the purposes of the project. All other accessory equipment and temporary structures (i.e., construction trailers) should be restricted from the floodway. Structures should be placed on site so that flood damages are minimized. Anchoring the construction trailers in case, evacuation is not practical.
P. 
Similar uses as those listed in this section.
The following uses and activities and their accessory uses and activities may be permitted in the A-1 zone when approved under Chapter 16.220, Conditional Use Permits. These uses and activities are also subject to the provisions of Section 16.72.040, Development Standards. These uses and activities may be permitted if found consistent with the purpose of this zone and with the purpose of adjacent shoreland zones.
A. 
Mining and mineral extraction.
B. 
Active restoration.
C. 
Bridge Crossing Support Structures. Temporary encroachments in the floodway for the purposes of bridge construction and repair:
1. 
This use shall comply with Chapter 16.88 (Flood Hazard Overlay (FHO) District) prior to issuance of any permits.
2. 
The temporary permit shall state the number of days the structure or other development will be on the site. If a longer period is required, a new permit shall be issued.
3. 
A flood warning system for the project should be in place to allow equipment to be evacuated from the site and placed outside the floodplain.
4. 
Placement of equipment in the floodway should be restricted to only equipment which is absolutely necessary for the purposes of the project. All other accessory equipment and temporary structures (i.e., construction trailers) should be restricted from the floodway. Structures should be placed on site so that flood damages are minimized. Anchoring the construction trailers in case evacuation is not practical.
