The measure requires that marina siting and design allow for maximum flushing of the water supply for the site. Adequate flushing reduces the potential for the stagnation of water in a marina and helps to maintain the biological productivity and reduce the potential for toxic accumulation in bottom sediment. This measure specifies that water quality be considered in the siting and design of both new and expanding marinas. Marinas should be designed and located so as to protect against adverse impacts on shellfish resources, wetlands, submerged aquatic vegetation, and other important habitat areas as designated by local, state, or federal governments. Where shoreline erosion is a nonpoint source pollution problem, shorelines should be stabilized.
Vegetative methods are strongly preferred unless structural methods are cost-effective.
This measure, which applies to runoff from the marina site only, specifies implementation of runoff control strategies which include the use of pollution prevention activities and the proper design of hull maintenance areas. This measure specifies that fueling stations should be located and designed so that, in the case of an accident, spill contaminants can be contained in a limited area. This measure specifies that solid wastes produced by the operation, cleaning, maintenance, and repair of boats should be properly disposed of to limit their entry to surface waters. In sufficient quantity, fish wastes can result in the depletion of dissolved oxygen and odor problems. To address this concern, the measure requires that sound fish waste management be promoted through a combination of fish cleaning restrictions, public education, and proper disposal.
