Environmental Design for Small Boat Basins


Quiz Questions

1.Small boats are classified as recreational craft, fishing boats, or other small commercial craft with lengths less than 100 ft (31 m). A small boat basin is a place to obtain essential supplies such as food, fuel, and drinking water. Small boat basins provide direct access to each boat, adequate depth of water, parking, toilet facilities, technical services, shops, and other amenities. Small boat basins are found on coastlines, estuaries, lakes, and riverbanks.
True
False
2. The U.S. Army Corps of Engineers permitting process is represented in _________________.

3.Saltwater harbors supporting deep-sea fishing are generally located within 15 miles (24 km) of open water. A 5-ft (1.5-m) minimum channel depth is usually maintained.
True
False
4. Freshwater recreational fishing is supported by marinas, harbors, and access facilities on natural lakes, reservoirs, and inland waterways. Facilities for lake and reservoir fishing are often on the shoreline. Waterway harbors are located within 5 miles of fishing waters. Minimum depth for channels is 4 ft, with easy navigation resulting from readily identifiable landmarks and numerous guides to navigation.
True
False
5. A small boat basin should have the following site characteristics: Easy access to open water, Accessibility from roads and waterways, Location in protected waters, Location near navigable water, Access to areas suitable for dredged material disposal, High tides and flushing rates, Compatibility with existing land and water uses, Good water quality, Absence of commercial shellfish beds, Low value as a fish and wildlife habitat & Absence of rare, threatened, or endangered species.
True
False
6.Figure 3-3 represents the typical cross section of a rubble-mound jetty.
True
False
7. The table that represents the maximum number of boats per acre is __________________.

8.Mooring piles at the outmost end of the slip allow stern-to-bow mooring (Figure 3-5). For slips longer than about 25 ft (7.6 m), an additional mooring pile should be placed about halfway down the length of the slip. This additional pile, called a spring pile, helps restrain the fore and aft motion and provides protection between boats of adjacent slips.
True
False
9.Mechanical harvesting of aquatic plants should be considered when areas are small, or when biological techniques are not appropriate. A mechanical harvester moves through the water, and cuts and processes the plants, which can be placed back in the water or loaded on a barge and shipped to shore for disposal.
True
False
10.Figure 4-1 represents the Erosion and accretion patterns in association with detached and attached breakwaters.
True
False
