Editing Permeable paving (section)

=== Cost ===
It can be difficult to compare cost impacts between conventional impervious surfaces and permeable surfaces given the variables such as lifespan, geographic location, type of permeable paving system and site specific factors. Some estimates put the cost of permeable paving at about one third more expensive than that of conventional impervious paving.<ref>{{Citation |last=Wright |first=G.B. |year=2011 |title=Urban creep in Scotland: stakeholder perceptions, quantification and cost implications of permeable solutions |journal=Water and Environment Journal |volume=25 |issue=4 |pages=513–521 |doi=10.1111/j.1747-6593.2010.00247.x |location=Edinburgh |bibcode=2011WaEnJ..25..513W |s2cid=109698597 |url=https://onlinelibrary.wiley.com/doi/full/10.1111/j.1747-6593.2010.00247.x |access-date=2020-12-13}}</ref> Using permeable paving, however, can reduce the cost of providing larger or more stormwater [[Best management practice for water pollution|BMPs]] on site, and these savings should be factored into any cost analysis. In addition, the off-site environmental impact costs of not reducing on-site stormwater volumes and pollution have historically been ignored or assigned to other groups (local government parks, public works and environmental restoration budgets, fisheries losses, etc.). Permeable paving systems, specifically pervious concrete pavers, have shown significant cost benefits after a [[Life Cycle Assessment]] was performed, as the reduction in total weight of material needed for each unit is reduced by nature of the porous design.<ref>{{Citation |last=Yuan |first=Xueliang |year=2018 |title=Environmental and economic impacts assessment of concrete pavement brick and permeable brick production process - A case study in China |journal=Journal of Cleaner Production |volume=171 |publisher=Journal of Cleaner Production Vol. 171 |pages= 198–208 |doi=10.1016/j.jclepro.2017.10.037 |bibcode=2018JCPro.171..198Y |url=https://www.sciencedirect.com/science/article/pii/S0959652617323284 |access-date=2020-12-13}}</ref>
