Walkability is an important factor in fostering a sustainable and livable community that affects physical activity, social interaction, and general well-being. By evaluating the perception of walkability, on street greenery, and examining pedestrians' preferences for a walkable street setting design, this study examines street greenery as a factor of the built environment's design affecting how pedestrians in Lopez Avenue, Los Baños, perceive walkability. A quantitative survey was conducted with 262 pedestrians who were randomly picked along the stretch of the study area to gather information on the perceived walkability, encompassing comfort, attractiveness, safety, and accessibility. To determine desire for a walkable neighborhood in particular, a stated preference survey with manipulated street scenarios was utilized. Perception and preferences were analyzed using descriptive and inferential statistics. The findings indicate a positive correlation between street greenery and the perceived walkability, albeit its weak association. Particularly, the respondents expressed greater satisfaction and enhanced comfort with the presence of street greenery. Additionally, the presence of street trees at pits along the avenue was found to be favorable to make the area more walkable. The results of this study have implications for urban planning and design, highlighting the significance of integrating street greenery to enhance walkability.
