택지개발사업에 의한 근린공원의 개발비용분석

택지개발사업으로 조성되는 근린공원의 개발 특성과 비용을 분석했다.

In general, neighborhood parks resulting from housing estate development project are preserved natural forests within parks created on a new ground that is artificially laid through earth works. How a park has been developed influences the characteristics of the park such as land use, park facilities, planted trees and construction costs. Thus the present study attempted to compare and analyze these characteristics and propose rational and efficient directions and ideal options for park planning and development in the future.

In addition, it was focused on defining reasonable processes of introducing preserved neighborhood parks and created ones and suggesting methods for proper construction cost estimation, optimal land use planning, right facility deployment, etc. Subjects of the research were eight created neighborhood parks and seven preserved ones, which were within sites in Daegu or Gyeongsangbuk-do where housing estate development had been completed or was in progress. These parks were analyzed in terms of the reality of development by type, construction cost, and unit construction cost efficiency chronically before and after the work. Conclusions drawn from the analysis are as follows. 1.

When comparing the number of changes in design for the whole landscaping in sites with that for the neighborhood park, the ratios are between 50-87 % except Daegu Dongho Site and Daegu Seongseo the 3rd Neighborhood as well as Gyeongsan Sadong Site, Andong Jeongsang Site and Kimcheon Bugok Site, in which the number of changes in design was three or less. 2. According to the result of calculating the construction cost per ㎡ by dividing the park construction cost into the area of the park and comparing cost efficiency, the cost per unit area in created parks is 4.1 times higher than that of preserved parks. 3.

As for construction cost per ㎡ in individual sites in Daegu and Gyeongsang buk-do, created parks cost between 21,000-50,000 won per ㎡ except that in Daegu Chilgok the 2nd Site, the unit cost of which is beyond the deviation range, and preserved parks cost between 1,300-3,800 won per ㎡ except those in Daegu Seongseo 4 and 5 neighborhood, the unit cost of which is beyond the deviation range. Thus the unit construction cost of created parks was 13-15 times higher than that of preserved parks.

In comparison between the two types of parks in the whole country as well, the unit construction costs of created parks ranges between 24,100-31,800 won while that of preserved parks between 3,600-9,300 won. Thus the former is 3.4-6.75 times higher than the latter. The results of this study have been presented above as basic materials for planning and creating neighborhood parks in housing estate development site and forecasting proper construction cost by the work item, and by the unit work cost of parks as well as key indexes for optimal land use planning and facility deployment.

Considering the results, it is considered desirable to build preserved neighborhood parks than created ones, and to include plans to build sustainable parks using natural forests in planning land use for housing estate development.
