Description:
Abstract: This coverage provides information about the location and extent of different management units in the Chetco estuary, as defined in the Oregon Estuary Plan Book.
Purpose:
Each management unit is a discrete geographic area defined by biological and physical characteristics and features, within which particular uses and activities are promoted, encouraged, protected, or enhanced, and others are discouraged, restricted, or prohibited. Goal 16 defines three types of estuary management units: natural, conservation, and development. They are described in detail below. The type of management units-and therefore the uses-allowed in an estuary depend on its classification. Natural estuaries may only include natural management units. Conservation estuaries may include both conservation and natural management units, while development estuaries may include all three types of management units. Goal 16 requires that estuary plans list the uses permitted within each management unit. The Goal also prescribes the overall purposes of each type of management unit and limits the types of uses that are or can be allowed. The management
objective provides an overall standard for planning and for review of proposed uses. Permissible uses are uses which are generally considered consistent with achieving the state management objective. Consequently, permissible uses are routinely approved, provided they meet other standards in the Goal for impact minimization. Resource capability uses may or may not be consistent with the management objective, depending on the size and location of the use and the resources affected.
Supplemental Information:
Management unit boundaries are determined by the types of resources present in the estuary and the extent of past
alterations. Local planners relied on published inventories and other state and federal agency studies and, when necessary, also made onsite visits to determine the precise extent of various types of habitat. Most planners based their judgments on the Oregon Department of Fish and Wildlife's estuary habitat maps Decisions about what constitutes a "major tract," "less biological significance," or "minimal biological significance" are judgments made by local governments which must be based on several factors. The major factor is the relative abundance of the particular habitat in the estuary. Existing
development and past alterations were also important factors if they affect habitat quality. In either case, judgments about habitat significance were usually made with the assistance of state and federal resource agencies.
Disagreements were resolved by LCDC at the time of plan acknowledgment. Changes after acknowledgment are subject to
review against both the Goals and the policies in the adopted estuary plan.

Original Base maps were prepared by the Division of State Lands in 1972 and 1973 using aerial photographs from the U.S. Geological Survey USGS EROS Data Center, NASA). These base maps were used in 1978 and 1979 by the Oregon Department of Fish and Wildlife in its mapping of estuarine habitats as part of DLCD's estuary inventory project. ODFW used aerial photography, published studies, and some onsite investigation to prepare its maps of estuarine habitats.
Estuary and shoreland planning designations were compiled from local plans in 1986-87 by DLCD. Neither the DSL base nor ODFW study cover the Columbia River estuary. The base map for this area is a 1" = 1000' map prepared by the Columbia River Estuary Data Development Project (CREDDP) in 1983. Habitat information for the Columbia River was prepared by staff of the Columbia River Estuary Study Task Force (CREST) in 1985. CREST compiled various CREDDP studies, converted data to the ODFW habitat classification, and prepared the habitat map provided here.
Comprehensive plan and habitat maps were digitized by the Oregon Department of Energy in 1986 and 1987 using an ARC/INFO Geographic Information System. Full scale maps (usually at 1" = 1000') were photographically reduced to fit the format of the Plan Book document, and are produced at varying scales.
Digitized maps were reviewed by DOE and DLCD staff to identify inconsistencies and digitizing errors. The most common inconsistency was disagreement between the ODFW Habitat Map and the local plan maps in establishing the location of the estuary shoreline. DLCD staff reviewed aerial photographs. plan documents, and consulted with local planners to resolve inconsistencies.

NATURAL MANAGEMENT UNITS
Areas Included: Major tracts of salt marsh, tideflats, and
seagrass and algae beds. Management
Objective: To assure the protection of significant fish and
wildlife habitats, continued biological productivity in the
estuary, and scientific research and educational needs.
These areas are to be managed to preserve the natural
resources in recognition of dynamic natural, geological and
evolutionary processes.
Permissible Uses: Undeveloped
low-intensity, water-dependent recreation; Research
and educational observation; Navigation
aids, such as beacons and buoys; Protection
of habitat, nutrient, fish, wildlife and aesthetic
resources; Passive
restoration measures;
Dredging necessary for on-site maintenance of existing
functional tidegates and associated drainage channels, and
bridge crossing support structures; Riprap
for protection of uses existing as of October 7, 1977;
unique natural resources; historical and archeological
values; and public facilities; and Bridge
crossings. Resource
Capability Uses: Aquaculture
which does not involve dredge or fill or other estuarine
alteration, other than incidental dredging for harvest of
benthic species or removable in-water structures such as
stakes or racks; Communication
facilities; Active
restoration of fish and wildlife habitat or water quality
and estuarine enhancement;
Boat ramps for public use, where no dredging, fill, or
navigational access is needed; Pipelines,
cables and utility crossings, including incidental dredging
necessary for their installation; Installation
of tidegates in existing functional dikes; Temporary
alterations; and Bridge
crossing support structures and dredging necessary for
their installation. CONSERVATION
MANAGEMENT UNITS
Areas Included: Tracts of significant habitat smaller or of
less biological importance than those included in natural
management units, and recreational or commercial oyster and
clam beds not included in natural management units. Areas
that are partially altered and adjacent to existing
development of moderate intensity which do not possess the
resource characteristics of natural or development units
are also included in this classification. Management
Objective: To provide for long-term uses of renewable
resources which do not require major alterations to the
estuary, except for the purpose of restoration. These areas
are to be managed to conserve natural resources and
benefits. Permissible
Uses: Permitted
and """"conditional"""" uses allowed in natural management units
(except temporary alterations). Resource
Capability Uses: High-intensity
water-dependent recreation, including boat ramps, marinas
and new dredging for boat ramps and marinas; Minor
navigational improvements; Mining
and mineral extraction, including dredging necessary for
mineral extraction; Other
water-dependent uses requiring occupation of water surface
area by means other than dredge or fill; Aquaculture
requiring dredge or fill or other alteration of the
estuary; Active
restoration for purposes other than protection of habitat,
nutrient, fish, wildlife and aesthetic resources; and
Temporary
alterations. DEVELOPMENT
MANAGEMENT UNIT REQUIREMENTS
Areas Included: Deep-water areas adjacent or in proximity
to the shoreline, navigation channels, subtidal areas for
in-water disposal of dredged material, and areas of minimal
biological significance needed for uses requiring
alteration of the estuary. Management
Objective: To provide for navigation and public,
commercial, and industrial water-dependent uses consistent
with the level of alteration allowed by the overall estuary
classification. Permissible
Uses: Dredge
or fill, as allowed elsewhere in the goal; Navigation
and water-dependent commercial enterprises and activities;
Water
transport channels where dredging may be necessary;
Flow-lane
disposal of dredged material, monitored to assure that
estuarine sedimentation is consistent with the resource
capabilities and purposes of affected natural and
conservation management units; Water
storage areas where needed for products used in or
resulting from industry, commerce, and recreation; Marinas;
Aquaculture;
Extraction
of aggregate resources; and Restoration.
Resource
Capability Uses: Water-related
and nondependent, nonrelated uses not requiring dredge or
fill; Mining
or mineral extraction; and Other
uses and activities allowed in natural and conservation
management units.
