THE USE OF MJTIOATION IN ENVIRONMENTAL PLANNING FOR PORT DEVELOPMENT Donald R. Deis and R. Steve Dial Continental Shelf Associates 759Parkway Street Jupiter, FL 33477 Millicent L. Quammen NCROUSWFS 1010 Gause Blvd. Slidcll, LA 70458 Thio study conducted under contract from USFWS consisted of four tasks: 1) Review and evaluate past aitigation projects in the Tampa Bay area; 2) prepare a list of feasibility options; 3) identify and rank potential mitigation sites; and 4) develop management and/or restoration recommendations. Auble et al. (1985), in a report on a workshop in which mitigation options to port development in Tampa Bay were suggested, discussed two classes of mitigation options: those designed to avoid, minimize, rectify, or reduce the adverse impacts of development, and those designed to compensate for unavoidable impacts. This document discusses the second class of mitigation options—-those involving compensation for impacts whore there is loss of habitat* However, implementation of management practices designed to reduce or avoid further impacts on Tampa Bay by port and othor typos of development are recommended before allowing development requiring compensation. These management practices are also an important part of any program developed to improve water quality and wetlands habitat within Tampa Bay. Evaluation of Past Mitigation Projects Ten sites where restoration was to have occurred were evaluated. These included filling of a subtldal area and plantings of black needlerush (Juncus roemerlanus), mangroves (Rhitophora mangle. Avicennia germinans, and Laguncularia racemose), and smooth cordgrass (Soartina alterniflora). Two of tho sites were plantings on dredge-spoil islands. Specific goals were not stated for most of 707

There is a growing needto precisely delineate offshore fish andshellfishhabitat.<br />

Current fishery management practice is dependent upon delineation of key nursery<br />

spawning and feeding areas. .Plans foroffshore oil andgasdevelopment alsorequire<br />

accurate habitat mapping. A geographic information system is designedto process large<br />

volumes of spatial data, presenting results in graphic form forinteractive use by resource<br />

managers. While a large body of specialized hardware and software exists, use of<br />

geographic information systemsin marine resource management is limitedby <strong>the</strong> type and<br />

an experimental geographic information system wascreated. Stadstical andcartographic<br />

manipulation of <strong>the</strong> data indicate thatmapping of environmental variables thateffect fish<br />
