Level of Development or Alteration

Intentionally left blank —Ed.(a)
Natural estuaries shall be managed to preserve the natural resources and the dynamic natural processes. Those uses which would change, alter, or destroy the natural resources and natural processes are not permitted. Natural estuaries shall only be used for undeveloped, low intensity, water-dependent recreation; and navigation aids such as beacons and buoys; protection of habitat, nutrient, fish, wildlife, and aesthetic resources; passive restoration measures, and where consistent with the resource capabilities of the area and the purposes of maintaining natural estuaries, aquaculture; communication facilities; placement of low water bridges and active restoration measures. Existing man-made features may be retained, maintained, and protected where they occur in a natural estuary. Activities and uses, such as waste discharge and structural changes, are prohibited. Riprap is not an allowable use, except that it may be allowed to a very limited extent where necessary for erosion control to protect:(A)
Uses existing as of October 7, 1977;(B)
Unique natural resource and historical and archeological values; or(C)
Public facilities; and where consistent with the natural management unit description in Goal #16 (and as deemed appropriate by the permitting agency).(b)
Natural estuaries shall contain only natural management units, as provided in the Estuarine Resource Goal.(2)
Conservation estuaries shall be managed for long-term uses of renewable resources that do not require major alterations of the estuary. Permissible uses in conservation management units shall be those allowed in section (1) of this rule; active restoration measures; aquaculture; and communication facilities. Where consistent with resource capabilities of the management unit and the purposes of maintaining conservation management units, high-intensity water-dependent recreation; maintenance dredging of existing facilities; minor navigational improvements; mining and mineral extraction; water dependent uses requiring occupation of water surface area by means other than fill; bridge crossings; and riprap shall also be appropriate. Conservation estuaries may have shorelines within urban or developed areas. Dredged marinas and boat basins without jetties or channels are appropriate in conservation estuaries. Waste discharge meeting state and federal water quality standards would be acceptable. Maintained jetties and channels shall not be allowed. Conservation estuaries shall have both conservation and natural management units, as provided in the Estuarine Resource Goal.(3)
Intentionally left blank —Ed.(a)
Both shallow and deep draft development estuaries shall be managed to provide for navigation and other identified needs for public, commercial, and industrial water-dependent uses consistent with overall Estuarine Resources Goal requirements. Where consistent with the development management unit requirements of the Estuarine Resources Goal, other appropriate uses include riprap and those uses listed as permissible uses in development management units in the Estuarine Resources Goal. Minor and major navigational improvements are allowed in both shallow-draft and deep-draft estuaries, consistent with the requirements of the Goal. However, in shallow-draft estuaries, extension or improvements in main channels shall not be designed to exceed 22 feet in depth. Information about the location, extent, and depth of channels and jetties including planned extensions, shall be developed during the local planning process and described in the comprehensive plan;(b)
Shallow and deep-draft development estuaries shall have natural, conservation, and development management units as provided in the Estuarine Resources Goal.
