As public service amenities, Urban Green Space (UGS) provides numerous benefits to inhabitants' daily lives and social activities. However, the coverage of UGS to urban residents is usually unequal, resulting in underutilized areas. This study assessed the UGS per inhabitant in Marka, Amman/Jordan in order to determine the categories of UGS that comprise the area's per capita value and to compare them to international standards. Gini coefficient and Lorenz curve were used to assess the spatial equity of public parks per capita in Marka area. This research also examined pedestrian accessibility to UGS in Marka according to the NRPA standards, employing the geographic information system network analysis approach (GIS). Furthermore, Location Allocation analysis was used to suggest a new public park locations and to assess the impact of this on improving accessibility for Marka's population. According to the study results, the actual per capita for the existing public parks in Marka is only .5 m2/capita, which is far below international standards, and the public parks are unevenly distributed according to Lorenz curve and Gini coefficient. However, the percentage of the served residential areas from the existing public parks is only 18.9 %, that should increase to 27.5 % after proposing three new public parks based on the location allocation analysis results. According to the findings of this study, GAM and municipalities should take a systematic approach to address the spatial distribution of UGS, in addition to a proactive engagement of planners, landscape architects, and designers in the planning process.
