This study aims to improve the effectiveness of the Environmental Impact AssessmentOrdinance in Incheon Metropolitan City by proposing an expanded scope of target projects based oninstitutional limitations and local development conditions. Focusing on large buildings and urbanredevelopment projects, the analysis reviewed relevant legislation, Incheon’s current EIA system (SEA,EIA, SEIA, and ordinance-based EIA), and records of building permits and redevelopment activities. The results show that approximately 2.7 new annual assessments would arise from buildings with atotal floor area of 100,000 m2 or more, and about 1.8 cases from redevelopment projects of 150,000-300,000 m2. Major local governments such as Seoul and Busan already include these projects in theirordinance-based EIAs, conducting around ten assessments each year; applying similar criteria to Incheon would generate roughly 4.5 additional cases. To address assessment blind spots and establisha regionally tailored framework, Incheon must amend its ordinance and strengthen institutionalcapacity through specialized agency delegation and additional personnel. The study providesempirical evidence that incorporating buildings and redevelopment projects into ordinance-basedEIAs can enhance environmental governance and support sustainable urban development.

This study empirically examined the operational characteristics and spatial distribution ofthe Mini Environmental Impact Assessment (EIA) system by comprehensively analyzing cases in thepower facility sector conducted between 2012 and 2024. The analysis was based on project data registered in the Environmental Impact Assessment Information Support System (EIASS), categorizedby business type, annual trends, regional concentration, and location regulation characteristics. Theanalysis identified a total of 9,476 consultations, with solar power projects accounting for more than95% of the total. The number of consultations increased sharply between 2017 and 2018, driven byrenewable energy expansion policies and Renewable Energy Certificate (REC) weighting incentives,but later declined as regulations were strengthened. Regionally, consultations were concentrated inthe southwestern plains—particularly in Jeollanam-do and Jeonbuk State—reflecting the combinedeffects of site suitability and local government policies. In terms of location regulations, over 86% ofconsultations occurred in management and agricultural zones, while a limited number were alsoconducted in certain protected areas. These findings underscore the importance of cumulative impactmanagement and the establishment of region-specific strategies, as Mini EIAs are highly responsiveto policy shifts and the regulatory environment. Accordingly, this study provides baseline informationthat can inform policy discussions on enhancing coherence between renewable energy expansion andenvironmental sustainability.

This study analyzed plant species composition and vegetation changes over time acrossnine wildlife crossing structures (WCSs). A total of 166 taxa were identified, comprising 56 families,128 genera, 155 species, 3 subspecies, 6 varieties, 1 forma and 1 hybrid, with Asteraceae, Poaceae, andFabaceae showing high occurrence frequency. Analysis of dormancy form revealed a higherproportion of perennial plants, particularly hemicryptophytes and woody species. A total of 24naturalized plant species were recorded, and species such as Erigeron annuus (L.) Pers., Oenotherabiennis L., and Robinia pseudoacacia L. were frequently observed. When comparing early-, middle-, andlate-stage WCSs, early and middle stages were dominated by herbaceous species adapted to dry anddisturbed habitats, while late stage WCSs showed an increased presence of forest edge species. A stabilization trend dominated by native species was observed along natural succession. Actualurbanization index decreased after 10 years of corridor establishment, indicating gradual stabilizationof habitat conditions.
