Minimum requirements shall be as follows:

Maximum regulations shall be as follows:

Additional regulations shall be as follows:

The site of a marina should require minimal dredging, both initially and for maintenance, and shall have a total flushing time of less than four days. Other guidelines regarding the siting of a marina include the following:

Unless a natural protective harbor configuration exists or the marina basin is primarily landlocked, breakwaters must be designed to reduce the velocity of waves entering a marina. These breakwaters, whether fixed or floating, absorb and reflect wave action and should be perpendicular to the normal wave approach. Solid rock or fill breakwaters are not permitted. Three-inch spacing between vertical slats and 18 inches off the bottom shall be provided to allow for circulation and migration of fish. Floating breakwaters are preferred in low-energy areas where wave lengths are less than twice the width of the breakwater.

Sloping riprap bulkheads are preferred over solid vertical structures as they better dissipate wave energy and provide a more diverse habitat for marine organisms.

For safety and comfort and to avoid interference with commercial boating activity, marinas shall be designed so that wave heights do not exceed two to four feet in the entrance channel and one to 1.5 feet in the berthing area.

The water area of the marina must be designed to accommodate boat slips of the appropriate sizes (as determined by the needs of assessment). Access to the slips via the channel and the fairways from the marina entrance must be safe and convenient.

The entrance channel of the marina must be constructed to facilitate the safe passage of boats in all weather conditions and must be located in a position to avoid direct wave action if possible. The width of the marina entrance channel should be at least four times the beam of the widest expected vessel to meet minimum safety requirements. The depth should be equal to the draft of the deepest draft boat likely to use the marina, plus half the expected wave height, as well as one or two feet of extra clearance. Entrance channels should not be located on corners.

In the marina design, the channel that connects the marina entrance to the boat slips or docking areas should be twice as wide as the entrance to the marina. The fairways, or areas between rows of boat slips, shall be 1.5 times wider than the length of the longest slip to allow for maneuverability. The layout of the channel and fairways shall take into consideration the prevailing winds and the currents in the area and entrance channels shall be oriented in the direction of the prevailing winds to promote wind-driven circulation. Additionally, turning areas shall be provided that are at least 2.25 times the length of the longest boat likely to use the marina in order that transient boaters may utilize the fuel dock and other facilities.

The depth of the basin shall not exceed the depths of the access channel or the open water to which the basin is connected, and enclosed basins shall include openings at opposite ends to promote circulation. The arrangement of the boat slips is parallel to currents as this promotes circulation and reduces the load on the pier structure. Whether a fixed pier or a floating pier is utilized, slips shall be at right angles to the direction of short wave length waves in the basin and to their adjacent walkway and shall be grouped according to their size. The deeper draft boats shall be near the channel to minimize dredging and smaller boats closer to the shore where the water is shallower. Boat slip width depends on both the length of boats and type of pier system utilized.

The walkways to the boat slips or piers can be either fixed or floating and shall be at least six feet wide to function safely and adequately. They shall also have utility hookups for each slip.

To minimize the impact on the photic zone, dock and pier widths should be minimized. The structures shall stand as high above mean high water as possible and shall be oriented north-south when possible.

Finger piers three feet wide are recommended for marina design in most cases because of their ease in allowing bow-to-mooring and because of their safety consideration. The most effective finger pier arrangement is in double wide slips [except for boats longer than 35 feet]. User acceptance indicates that floating piers are preferable to fixed piers.

Marinas should provide rest rooms according to the following schedule:

Rest rooms should provide both hot and cold water and should be maintained in a sanitary, warm, dry, brightly lit and well-ventilated condition.

Land-side or on-shore facilities and services must also be designed to accommodate the safety and pleasure of the boating public. Water-related activities such as swimming areas, beaches, playgrounds or fishing piers should be designed in conjunction with the marina. When developed as part of a municipal park, a marina enjoys wider public acceptance.

The dockmaster's office is the administrative center of the marina and as such should be easily accessible by both water and land.

The planning of the location of the fuel dock should give priority to safety considerations and should be designed to accommodate four of the largest expected vessels. The best location for the fuel dock is near the entrance to the marina and the dockmaster's office. It must be accessible to the fuel delivery trucks. At least 200 feet of unobstructed pier is recommended for fuel docks, and fuel pumps should include back pressure cutoff valves. Main cutoff valves should be available both at the dock and the upland area of the marina. "No-discharge" signs shall be posted throughout the marina fuel dock and basin area.

Boat storage racks offer flexibility in site utilization because smaller boats can be stacked until the owners decide to use them. They can then be retrieved and lowered into the water.

Other off-season boat storage must also be provided for a marina site as most boats are hoisted out of the water during the winter (unless a bubbler system is utilized).

Convenient and adequate parking must be provided. Ample parking facilities should be provided with a minimum of 0.6 spaces per slip with up to 2.5 spaces per slip depending upon the nature of the marinas. Parking areas should be properly screened and landscaped and must be accessible to marina equipment since these parking areas can also be used for off-season boat storage. The distance from a parked car to a slip should not exceed 600 feet. Parking space for cars and trailers should be designed at forty-five-degree-angles and should be reasonably close to the launch ramps.

Marinas should provide, as a minimum, one pumpout station (fixed or portable) for every twenty-boat slips.

Marinas which allow occupation of berth vessels for a period of 72 hours or more should provide slipside pumpout facilities. Pumpout facilities should be designed with holding tanks in order to prevent inputs into both septic and sanitary waste systems as MSD disinfectants disrupt the functioning of these systems.

Marinas shall provide abundant trash receptacles along with adequate fish cleaning areas, including separate and well-marked dispensers for organic refuse. The dumping of porta-potties, pumpout effluents or holding tanks into septic systems shall be prohibited. A recycling plan for solid waste, including receptacles for aluminum, brown, green and clear glass and newspapers, shall be provided.

Marinas shall incorporate an aesthetically pleasing and easy to maintain landscaping plan in their design in order to enhance the natural environment. In addition, landscaping can be utilized to properly screen maintenance areas which should be located as far from the water as possible.

During construction of the marina, standards to protect the environment include the following:

The site of the marina and the needs of the population of the service area will dictate the nature of ancillary marina services. The services can range from a simple rest room/vending machine/ice and bait house concession area to an elaborate complex including waterfront restaurants and other recreation activities, such as pools and tennis courts.

Create some variety in the public access experience by providing pedestrian spaces or nodes, especially in marina projects which are often linear in nature. Provide public access for fishing on piers and breakwaters.

Provide public boat launching ramps.

Set uses that do not relate to the waterfront, including offices and parking well back from the shoreline. Provide maximum access along the shoreline and screen the shoreline from incompatible uses.

Provide improvements, including landscaping, benches and paving, that are appropriate for the anticipated demand, size and location of the project.
