Feedback on Permeable paving

Overview section - You may want to add to the list of bullet points: Composite plastic/recycled rubber permeable unit pavers Under the 'fundamental' heading - 3rd Bullet 'cast in place' should be changed to 'cast-in-place" Under the 'Uses' section...Overview section - You may want to add to the list of bullet points: Composite plastic/recycled rubber permeable unit pavers Under the 'fundamental' heading - 3rd Bullet 'cast in place' should be changed to 'cast-in-place" Under the 'Uses' section- Add to the list of additional components ' Impervious liner for installations where infiltration is not desirable including well-head, protection areas, high water table sites and sites where installations are proximate to building faces/foundations'. Pretreatment section - Last sentence - Change the word 'element' to 'method' Risk of Groundwater Contamination section - 2nd bullet - Add a comma after 'such as' This section would benefit from some discussion related to the use of an impervious liner and an underdrain to provide a barrier to protect groundwater. The system functions as a 'filtration/attenuation' installation. Private Systems section - Last sentence - Change 'existing practices' to 'existing permeable pavement installations'. Design section - Finish course - 1st sentence - chage 'of' to 'for and add 'specific' ('for their specific product'). Performance section - This section would benefit from some discussion related to attenuation/filtration (non-infiltration type installations). On urban sites where underground parking garages are lot-line to lot-line, we commonly use permeable pavement with a liner and a stone reservoir as a tool to achieve SWM targets. This technique is one of the few means available to assist on very tight sites or within projects that are located on Brownfield sites that have been remediated through capping to encapsulate contaminated subsoils.More

ASCE standard for permeable pavers should be referenced. Base depths and layering specifications are provided in this document. Consider referencing these depths here for easy reference.

Under title "Heavy vehicle traffic" suggest we provide some examples of products suitable for heavy vehicle traffic and a link to where the reader can learn more about case studies or sites implemented.
