Generally, a parking lot is constructed using asphalt or concrete. Such materials are impermeable, which means that a
parking lot will directly release pollutants to any nearby water system during a rainfall event. An increased quantity of
nonpoint source pollutants harms the ecohydrological system and causes further environmental damage leading to
dysfunctional water circulation systems. Therefore, there is an urgent need for the design and application of Low Impact
Development (LID) systems that allow more effective prevention of water circulation problems and management of
nonpoint source pollution. This study aims to support such efforts by analyzing a permeable paver parking lot constructed
using one of the LID techniques and comparing it to a conventional one in terms of the concentration of pollutants,
nonpoint source pollution load and runoff rainfall lag effects during a rainfall event; it could serve as a reference for the
construction of permeable paver parking lots in the future.
