Parking lot grass paver design refers to the use of grass pavers, which are permeable interlocking concrete pavers, in the construction of parking lots. These pavers are designed to allow grass to grow through the gaps between them, providing a green, permeable alternative to traditional asphalt or concrete surfaces. They are often used in areas with strict stormwater management regulations and are beneficial for reducing urban heat island effect and improving water infiltration. The design of grass pavers includes considerations such as size, spacing, and the choice of grass species to ensure proper drainage and grass growth.
