Abstract:
This coverage provides information about the location and extent of mitigation sites in the Salmon estuary, as defined in the Oregon Estuary Plan Book.

Purpose:
One of the major objectives of estuary planning is to identify ways to repair the damage done to estuaries by past alterations. Mitigation and restoration planning identify shoreland sites that can be added to the estuary to increase estuarine values or offset effects of new development. The number and type of mitigation sites designated in plans must generally correspond to areas designated for development in the plan which would require mitigation. Mitigation and restoration involve the same types of activities but are done for slightly different reasons. Both involve actions which either restore an area to the estuary, create a new estuarine area, or enhance an existing estuarine area. However, mitigation is done to compensate for damage done by new development, while restoration is done to offset historical losses and reestablish past values.
Mitigation is required whenever intertidal dredge or fill is permitted. The type and amount of mitigation generally must replace the habitats and values lost at the development site. There is no specific Goal requirement to carry out restoration. Consequently, restoration projects are usually undertaken by resource or land management agencies to provide for overall enhancement of estuarine values.

Supplemental Information:
It is important to note that the term "mitigation" has different meanings under state and federal law. In Oregon, mitigation only includes compensating for unavoidable losses through habitat creation, restoration, or enhancement. Federal Agencies define mitigation much more broadly. They consider any method of reducing impacts of a proposed development project to be mitigation. Mitigation measures under federal law include redesign or relocation, as well as "compensation" for unavoidable habitat losses through creation or restoration of new areas. In terms of the federal definition of mitigation, Oregon's mitigation requirement is considered a compensation requirement.

Other Citation Details:
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.
