Section 3: Benefit-Cost AnalysisThis section attempts to estimate in financial terms the costs and benefits associated with carrying out the critical habitat hazard analysis. We consider the primary users of the end product to be policy makers, land-use planners and environmental/conservation groups promoting effective habitat conservation and management. Thus, we are making some key assumptions regarding the access of these groups and individuals to existing GIS technology. Those organizations from whom we have obtained data and with whom we have discussed this project are actively using GIS, though not necessarily for the kind of analysis we've developed here.
Technology Environment:
Based on discussions with representatives of these groups and reviews of the literature on hazard evaluation of critical habitat areas, this analysis complements and enhances existing methods and systems for quantifying and qualifying the nature of threats influencing these regions. It goes beyond what is commonly done to evaluate hazard factors by:
Antenucci Benefit Typology:Geographic Scale: This project addresses critical habitats over a larger geographic region, the Puget Sound basin. The majority of conservation groups operate on a local scale and larger efforts have regional focuses. With the data automation and processing capacity offered by GIS, this project is capable of considering all identified critical habitats in the region of analysis. Data Sources: Data sets that encompass the entire Puget Sound and contain sufficient detail to support critical habitat analysis are rare. This analysis utilizes detailed elevation and habitat coverages commonly utilized for conservation management along with land cover classifications from satellite imagery. Habitat influence processes: Typical habitat analyses have focused on factors inherent in the habitat: species diversity and habitat quality. This analysis considers habitats' relationships with external influences associated with flow, adjacency and change. It accounts for habitats’ area/edge and relationship to uphill flow zones as predisposing characteristics. Slope and distance to habitat are used as aggravating factors in consideration of uphill and adjacent influences respectively. Data Analysis: Each habitat region is considered independently of other habitats. This unusual approach to habitat analysis permits examination of each habitat in relationship to influencing land cover. GIS operations commonly available in standard software do not offer this ‘isolated object’ perspective and may underestimate the multiple effects of negative land cover impacts. Type One Benefits: Increased Efficiency. Focuses on how users may more efficiently carry out an assessment of the nature and magnitude of hazardous influence on habitat areas.
Cost Analysis in Three Categories: Capital, Operating and Opportunity/Hidden:
Cost Assumptions and Explanations:
Below is a more detailed delineation of the capital requirements and
labor tasks associated with the project. These have been aggregated for
the cost comparison chart which estimates the difference between attempting
to carry out this kind of analyses manually (a task we feel is virtually
impossible at this scale) and in the automated environment. Several decisions
warrant some explanation in interpreting the chart.

Operations Related ExpendituresThe following information is presented in aggregate in the included graphs and charts. The graph provides the decision maker with some image of the break-even point over project duration and the cost loading of the project. The chart provides a more nuanced understanding of what categories dominate expenses at which project stage and may be a better tool for cash flow management requirements.
- Labor.
- Three analysts working .75 time for 10 weeks at $20.00 per hour.
- Data preparation activity.
- Procuring satellite/remote sensing imagery.
- Interpretation time and remote sensing equipment.
- DEM conversion/pre processing.
- Landcover interpretation and ground truth.
- Field surveys for habitat confirmation.
- Promotion of and training in system use.
- Staff to promote new system and educate various end users on its applications and products.
- Systems Maintenance and Development.
- Network manager – meet part of payment on widely used network manager.
- Data management and upkeep.
- Systems management and upkeep.
- Researching survey control of integrated data.
- Depreciation of Hardware (20% per annum).
- Opportunity and Hidden Costs:
- Management staff time away from other activities .
- Key resources which undeveloped as money/time are put into the longer term payback of GIS development.
- Transition period entails training and new procedure development which may result in a temporary reduction of services to the public and to other users.

The graph illustrates an unusual pattern which differs markedly from the examples offered by Antenucci. This can be explained by the assumptions made during this analysis. Huge initial start up cost are often associated with the implementation of a GIS in a policy or other institutional environment. These frequently outweigh the costs associated with manual operations which may not exceed the automated model until well into the implementation of the system when efficiency benefits are realized.
However in this project, we assumed the existence of key equipment and data. The availability of both lowered important costs associated with the automated route and made the project cost-effective from the start. As the project proceeds toward final map production, the manual option which has required greater personnel costs throughout, becomes exceedingly expensive. This reflects our conviction that the types of maps and information products to come from this project would not be financially feasible without the support of a GIS.
In addition the GIS option may be more preferable based on benefits which may not be well captured here. Surveys of other staff members in the organization who have benefited from the project's products may better quantify some of the intangible benefits which may arise. An outside evaluation of efficiency in decision making before and after the project may also identify some measurable benefits derived from the project's implementation.
