For the Lever Homes we chose to go with 100% site permeability. To achieve this we are using Turf Stone for the driveway that allows pockets of grass to grow between the pavers. For the open spaces we are using a product called eco-priora that allows water to penetrate into the ground between the pavers. By making the site permeable we are able to mitigate water from being carried into the storm water system. Below are a few pictures showing the finished look.
