This creative project produced a Development Plan for the 60-year-old 200+ acre Cascades Park in Bloomington, Indiana. Combining principles of historic preservation with passive forms of unfacilitized recreation provided the framework for the final design concepts. The final product was the actual master development plan and 11 other 30" x 40" sheets that illustrated a thorough inventory and analysis of the park and its context, suitabilities of the park for specific forms of recreation, concepts, and graphic illustrations. The inventory and analysis sheets have sought to identify the unique character of the park that came about from two distinct sources: 1) The natural environment that spawned the interest for the area to become a park in 1924 and, 2) The park amenities in the forms of shelters, retaining walls, play equipment, water wells, drives, etc. that were added in the past 60 years indicating man's impact upon the area. The design concepts for the park emphasized and protected this unique character. The extent of information, both written and graphic, on the 12 sheets was intended to provide the information without needing an accompanying booklet or oral explanation from the designer. In addition to the site-specific information that was illustrated in the maps, general information was also required. To understand the social framework that was responsible for the creation of Cascades Park and other parks of the time, park planning principles of the 1920's were researched. These were then compared and applied where possible to the historic development of Cascades Park. Also, developmental criteria were established for forms of recreation that were found to be in demand in Bloomington and had the potential of being accommodated in the park with a minimal disruption of its natural beauty. / Department of Landscape Architecture

An important requirement of a rational policy for provision of outdoor recreation opportunities is some understanding of natural processes and public concern and /or preferences. Computerized land use suitability mapping is a technique which can help find the best location for a variety of developmental actions given a set of goals and other criteria. Over the past two decades, the methods and techniques of land use planning have been engaged in a revolution on at least two fronts as to shift the basic theories and attitudes of which land use decisions are based. The first of these fronts is the inclusion of environmental concerns, and the second is the application of more systematic methods or models. While these automated capabilities have shed new light on environmental issues, they, unfortunately, have failed to develop sufficient intelligence and adaptation to accurately model the dynamics of ecosystems.The work reported proceeds on the belief that neural network models can be used to assess and develop resource management strategies for Mounds State Park, Anderson, Indiana. The study combines a photographic survey technique with a geographic information system (GIS) and artificial neural networks (NN) to investigate the perceived impact of park management activities on recreation opportunities and experiences. It is unique in that it incorporates both survey data with spatial data and an optimizing technique to develop a model for predicting perceived management values for short and long term recreation management.According to Jeannette Stanley and Evan Bak (1988) a neural network is a massively parallel, dynamic systems of highly interconnected interacting parts based on neurobiological models. The behavior of the network depends heavily on the connection details. The state of the network evolves continually with time. Networks are considered clever and intuitive because they learn by example rather than following simple programming rules. They are defined by a set of rules or patterns based on expertise or perception for better decision making. With experience networks become sensitive to subtle relationships in the environment which are not obvious to humans.The model was developed as a counter-propagation network with a four layer learning network consisting of an input layer, a normalized layer, a kohonen layer, and an output layer. The counter-propagation network is a feed-forward network which combines Kohonen and Widrow-Hoff learning rules for a new type of mapping neural network. The network was trained with patterns derived by mapping five variables (slope, aspect, vegetation, soil, site features) and survey responses from three groups. The responses included, for each viewshed, the preference and management values, and three recreational activities each group associated with a given landscape. Overall the model behaves properly in learning the different rules and generalizing in cases where inputs had not been shown to the network apriori. Maps are provided to illustrate the different responses obtained from each group and simulated by the model. The study is not conclusive as to the capabilities of the combination of GIS techniques and neural networks, but it gives a good flavor of what can be achieved when accurate mapping information is used by an intelligent system for decision making. / Department of Landscape Architecture

During this creative project rationale, developed from scientific fact, community needs and the values inherent to the student was utilized as the foundation for decisions associated with the development of a campground facility for Prairie Creek Reservoir. Comprehensive and site specific problem-solving methods were used to form a broad overview of the park and recreation planning and design procedures available to landscape architects.At the comprehensive scale, a survey was conducted to assess the community need for the camping experience. An inventory of existing camping opportunities available to the residents of Delaware County was used, in conjunction with the survey results and recreation standards, in a supply/demand equation to determine the number and the type of camping facilities needed to meet present and future demand for the camping experience. The concept of camping at Prairie Creek Reservoir Park was viewed in this light.Site scale investigations began with the establishment of user and resource criteria. Natural, cultural and economic data were collected from the landscape contained within, and immediately surrounding, the property leased by the Muncie Park Board at the Prairie Creek Reservoir site. This information was analyzed in accordance with the design criteria to produce a series of computer generated maps. The student identified alternative campground sites within the site with the help of these visual aids. The campground site, best meeting the user needs and resource capabilities, was selected and a series of development proposals for the campground facility was prepared. / Department of Landscape Architecture
